Letters to Friend and Foe

Baruch Spinoza

Edited and with a preface by

Dagobert D. Runes


The letters that appear in this volume cover only the last two decades of Spinoza’s life and represent a mere fraction of the immense correspondence he carried on during his lifetime.

The story of Spinoza’s expulsion from the synagogue of the small Jewish community in seventeenth-century Amsterdam is well known by now. Christianized Holland held the slight, dark-complexioned, sickly Jewish philosopher in equal disdain. Only the presence of such important friends as the Dutch statesman Jan de Witt and the powerful merchant Simon de Vries saved the outspoken Spinoza from prosecution by the Dutch authorities. As it was, during his lifetime and for a hundred years thereafter, practically all of Europe considered Spinoza a “dangerous” atheist. It was not until the latter part of the eighteenth century that the new era of enlightenment delivered Spinoza to his rightful place among the truly great philosophers of the world.

Indeed, the first edition of Spinoza’s correspondence, which appeared in the year of his death, 1677, carried the notation: “Letters of some learned men to B.d.S. and the author’s replies, which should contribute no little to the understanding of his other works.” We see that even after his death it was still necessary to omit his name so that the distribution of his works might not be hampered.

One can readily understand, then, why so little of Spinoza’s correspondence was saved for posterity. To retain an epistle signed by Spinoza was tantamount to foolhardiness because, although the Protestant Church of Holland had liberated itself from the rigidity and the brutal inquisition tactics practiced by the Spanish Catholics, it still used the most severe measures to deal with dissidents and heretics.

Spinoza spent the first half of his life in the intimacy of Amsterdam’s Jewish community. His name appeared as late as 1655 among the donors for the celebration of Jewish religious holid; ays. He was one of the most diligent students of the rabbinical school in the city and became steeped in the teachings and literature of Judaism. He had obtained much knowledge and developed a profound grasp of rabbinics. Nevertheless, his restless spirit did not permit him to serve as a cleric.

Among the people of Jewish Amsterdam there were great numbers of Marranos—Jews from Spain and Portugal who had managed to remain alive by the pretense of accepting Christianity. Arriving in Amsterdam, they desired to return to the faith of their fathers under the protection of the Dutch government. It is in this light that we must understand the anxiety of the local Jewish community concerning the religious well-being of these prodigal Jews, especially those of the young generation, whose adherence to Judaism was of very recent origin.

Judaism has always permitted dissidents and heretics to carry on what it considered a meaningless preoccupation. But here was a most unusual and difficult situation—one that called for action. The remnants of Spanish and Portuguese Jewry had been compelled to raise their children—at least officially—in a different faith. The Elders and the family fathers were desperate to bring their offspring back to the Covenant.

Then there came that rebellious youth, Spinoza, preaching a gospel of reform: Religion Without Ritualism; Faith Without Providence; A Universe Without a Personal God.

The Rabbis and the Elders pleaded with the adamant twenty-four-year-old student, whose father had died a little more than a year earlier, to desist. But he refused. The resultant expulsion from the synagogue was unavoidable. To Spinoza, it was a meaningless gesture (he offered, humorously, to explain to the Elders how to proceed with it). But it accomplished one thing: it cut Spinoza completely off from his Jewish friends and acquaintances in Amsterdam. He had to move to Ouderkerk, a suburb of the city, but within four years of his expulsion he went on to two little towns near The Hague and, finally, to The Hague itself.

During the years that he resided in the suburb of Amsterdam, he made his living as a teacher of the philosophy of Descartes—and as a teacher of Hebrew. In fact, he prepared textbooks on each of these subjects, Cartesianism as well as Hebrew grammar. In the year of his expulsion he wrote an Apologia in his mother tongue, Spanish, a pamphlet which has unfortunately been lost to history. While traces of this Apologia may be found in his Theological-Political Tractate, this book is somewhat marred by a chagrin against his people, who he felt had been unkind to him.

While such sentiment is understandable, one must also appreciate that the Jewish community of Amsterdam consisted of harassed refugees whose small number comprised one of the few remaining settlements in Western Europe that had escaped relentless Christian assault and persecution. At the time of Spinoza’s expulsion from the synagogue, no Jew was permitted to live in England, Spain or Portugal. In other countries of Western Europe, such as Germany, France and what is today Italy, only a scattering of Jews survived—these in ghettos or by special local acts of “tolerance.” In the east, especially in Poland during those very decades, 100,000 Jews were massacred in the most brutal manner by Russian Cossacks.

In such an era of tribulation the Jews had no time or patience with philosophical subtleties that might tend to undermine the cruelly tested faith of Jewish youth. The Jews expelled Spinoza not because they wanted to but, rather, because they had to. And yet, much of what appeared rebellious and heretical in that century is acceptable theology today—the then radical religious principles of Baruch Spinoza, for example, can today be considered cornerstones of Reform Judaism.

Most of the personal references and some of the letters containing such were omitted by the editors of the very first Latin edition of Spinoza’s correspondence in order to avoid “differences” with the Protestant Church of Holland. Yet, through the pages of these theoretical and academic writings one can detect the brightness and be made aware of the dignity of Spinoza’s thinking.

I felt it would be presumptuous on my part—nor did I think this little book the place—to burden it with annotations, explanations and interpretations concerning the recipients of the letters and their background.

I do hope these pages will inspire the readers to seek out the major works of the philosopher, the Ethics and the Theological-Political Tractate.

Spinoza to Oldenburg.

[Spinoza defines “God,” and “attribute,” and sends definitions, axioms, and first four propositions of Book I. of Ethics. Some errors of Bacon and Descartes discussed.]

Illustrious Sir,—How pleasant your friendship is to me, you may yourself judge, if your modesty will allow you to reflect on the abundance of your own excellences. Indeed the thought of these makes me seem not a little bold in entering into such a compact, the more so when I consider that between friends all things, and especially things spiritual, ought to be in common. However, this must lie at the charge of your modesty and kindness rather than of myself. You have been willing to lower yourself through the former and to fill me with the abundance of the latter, till I am no longer afraid to accept the close friendship, which you hold out to me, and which you deign to ask of me in return; no effort on my part shall be spared to render it lasting.

As for my mental endowments, such as they are, I would willingly allow you to share them, even though I knew it would be to my own great hindrance. But this is not meant as an excuse for denying to you what you ask by the rights of friendship. I will therefore endeavor to explain my opinions on the topics you touched on; though I scarcely hope, unless your kindness intervene, that I shall thus draw the bonds of our friendship closer.

I will then begin by speaking briefly of God, whom I define as a Being consisting in infinite attributes, whereof each is infinite or supremely perfect, after its kind. You must observe that by attribute I mean everything, which is conceived through itself and in itself, so that the conception of it does not involve the conception of anything else. For instance, extension is conceived through itself and in itself, but motion is not. The latter is conceived through something else, for the conception of it implies extension.

That the definition above given of God is true appears from the fact, that by God we mean a Being supremely perfect and absolutely infinite. That such a Being exists may easily be proved from the definition; but as this is not the place for such proof, I will pass it over. What I am bound here to prove, in order to satisfy the first inquiry of my distinguished questioner, are the following consequences: FIRST, that in the universe there cannot exist two substances without their differing utterly in essence; SECONDLY, that substance cannot be produced or created—existence pertains to its actual essence; THIRDLY, that all substance must be infinite or supremely perfect after its kind.

When these points have been demonstrated, my distinguished questioner will readily perceive my drift, if he reflects at the same time on the definition of God. In order to prove them clearly and briefly, I can think of nothing better than to submit them to the bar of your judgment proved in the geometrical method.* I therefore enclose them separately and await your verdict upon them.

Again, you ask me what errors I detect in the Cartesian and Baconian philosophies. It is not my custom to expose the errors of others, nevertheless I will yield to your request. The first and the greatest error is, that these philosophers have strayed so far from the knowledge of the first cause and origin of all things; the second is, that they did not know the true nature of the human mind; the third, that they never grasped the true cause of error. The necessity for correct knowledge on these three points can only be ignored by persons completely devoid of learning and training.

That they have wandered astray from the knowledge of the first cause, and of the human mind, may easily be gathered from the truth of the three propositions given above; I therefore devote myself entirely to the demonstration of the third error. Of Bacon I shall say very little, for he speaks very confusedly on the point, and works out scarcely any proofs: he simply narrates. In the first place he assumes that the human intellect is liable to err, not only through the fallibility of the senses, but also solely through its own nature, and that it frames its conceptions in accordance with the analogy of its own nature, not with the analogy of the universe, so that it is like a mirror receiving rays from external objects unequally, and mingling its own nature with the nature of things, etc.

Secondly, that the human intellect is, by reason of its own nature, prone to abstractions; such things as are in flux it feigns to be constant, etc.

Thirdly, that the human intellect continually augments, and is unable to come to a stand or to rest content. The other causes which he assigns may all be reduced to the one Cartesian principle, that the human will is free and more extensive than the intellect, or, as Verulam himself more confusedly puts it, that “the understanding is not a dry light, but receives infusion from the will.” (We may here observe that Verulam often employs “intellect” as synonymous with mind, differing in this respect from Descartes.) This cause, then, leaving aside the others as unimportant, I shall show to be false; indeed its falsity would be evident to its supporters, if they would consider, that will in general differs from this or that particular volition in the same way as whiteness differs from this or that white object, or humanity from this or that man. It is, therefore, as impossible to conceive, that will is the cause of a given volition, as to conceive that humanity is the cause of Peter and Paul.

Hence, as will is merely an entity of the reason, and cannot be called the cause of particular volitions, and as some cause is needed for the existence of such volitions, these latter cannot be called free, but are necessarily such as they are determined by their causes; lastly, according to Descartes, errors are themselves particular volitions; hence it necessarily follows that errors, or, in other words, particular volitions, are not free, but are determined by external causes, and in nowise by the will. This is what I undertook to prove.

Spinoza to Oldenburg.

[Spinoza answers some of Oldenburg’s questions and doubts, but has not time to reply to all, as he is just setting out for Amsterdam.]

Illustrious Sir:—As I was starting for Amsterdam, where I intend staying for a week or two, I received your most welcome letter, and noted the objections you raise to the three propositions I sent you. Not having time to reply fully, I will confine myself to these three.

To the first I answer, that not from every definition does the existence of the thing defined follow, but only (as I showed in a note appended to the three propositions) from the definition or idea of an attribute, that is (as I explained fully in the definition given of God) of a thing conceived through and in itself. The reason for this distinction was pointed out, if I mistake not, in the above-mentioned note sufficiently clear at any rate for a philosopher, who is assumed to be aware of the difference between a fiction and a clear and distinct idea, and also of the truth of the axiom that every definition or clear and distinct idea is true. When this has been duly noted, I do not see what more is required for the solution of your first question.

I therefore proceed to the solution of the second, wherein you seem to admit that, if thought does not belong to the nature of extension, then extension will not be limited by thought; your doubt only involves the example given. But observe, I beg, if we say that extension is not limited by extension but by thought, is not this the same as saying that extension is not infinite absolutely, but only as far as extension is concerned, in other words, infinite after its kind? But you say: perhaps thought is a corporeal action: be it so, though I by no means grant it: you, at any rate, will not deny that extension, in so far as it is extension, is not thought, and this is all that is required for explaining my definition and proving the third proposition.

Thirdly. You proceed to object, that my axioms ought not to be ranked as universal notions. I will not dispute this point with you; but you further hesitate as to their truth, seeming to desire to show that their contrary is more probable. Consider, I beg, the definition which I gave of substance and attribute, for on that they all depend. When I say that I mean by substance that which is conceived through and in itself; and that I mean by modification or accident that, which is in something else, and is conceived through that wherein it is, evidently it follows that substance is by nature prior to its accidents. For without the former the latter can neither be nor be conceived. Secondly, it follows that, besides substances and accidents, nothing exists really or externally to the intellect. For everything is conceived either through itself or through something else, and the conception of it either involves or does not involve the conception of something else. Thirdly, it follows that things which possess different attributes have nothing in common. For by attribute I have explained that I mean something, of which the conception does not involve the conception of anything else. Fourthly, and lastly, it follows that, if two things have nothing in common, one cannot be the cause of the other. For, as there would be nothing in common between the effect and the cause, the whole effect would spring from nothing. As for your contention that God has nothing actually in common with created things, I have maintained the exact opposite in my definition. I said that God is a being consisting of infinite attributes, whereof each one is infinite or supremely perfect after its kind. With regard to what you say concerning my first proposition, I beg you, my friend, to bear in mind, that men are not created, but born, and that their bodies already exist before birth, though under different forms. You draw the conclusion, wherein I fully concur, that, if one particle of matter be annihilated, the whole of extension would forthwith vanish. My second proposition does not make many gods but only one, to wit, a Being consisting of infinite attributes, etc.

Spinoza to Oldenburg.

[Spinoza informs Oldenburg that he has removed to Rhijnsburg, and has spent some time at Amsterdam for the purpose of publishing the “Principles of Cartesian Philosophy.” He then replies to Boyle’s objections.]

Distinguished Sir,—I have at length received your long wished for letter, and am at liberty to answer it. But, before I do so, I will briefly tell you, what has prevented my replying before. When I removed my household goods here in April, I set out for Amsterdam. While there certain friends asked me to impart to them a treatise containing, in brief, the second part of the principles of Descartes treated geometrically, together with some of the chief points treated of in metaphysics, which I had formerly dictated to a youth, to whom I did not wish to teach my own opinions openly. They further requested me, at the first opportunity, to compose a similar treatise on the first part. Wishing to oblige my friends, I at once set myself to the task, which I finished in a fortnight, and handed over to them. They then asked for leave to print it, which I readily granted on the condition that one of them should, under my supervision, clothe it in more elegant phraseology, and add a little preface warning readers that I do not acknowledge all the opinions there set forth as my own, inasmuch as I hold the exact contrary to much that is there written, illustrating the fact by one or two examples. All this the friend who took charge of the treatise promised to do, and this is the cause for my prolonged stay in Amsterdam. Since I returned to this village, I have hardly been able to call my time my own, because of the friends who have been kind enough to visit me. At last, my dear friend, a moment has come, when I can relate these occurrences to you, and inform you why I allow this treatise to see the light. It may be that on this occasion some of those, who hold the foremost positions in my country, will be found desirous of seeing the rest of my writings, which I acknowledge as my own; they will thus take care that I am enabled to publish them without any danger of infringing the laws of the land. If this be as I think, I shall doubtless publish at once; if things fall out otherwise, I would rather be silent than obtrude my opinions on men, in defiance of my country, and thus render them hostile to me. I therefore hope, my friend, that you will not chafe at having to wait a short time longer; you shall then receive from me either the treatise printed, or the summary of it which you ask for. If meanwhile you would like to have one or two copies of the work now in the press, I will satisfy your wish, as soon as I know of it and of means to send the book conveniently.

[The rest of the letter is taken up with criticisms on Boyle’s book.]

Spinoza to Oldenburg.

[Spinoza writes to his friend concerning the reasons which lead us to believe, that “every part of nature agrees with the whole, and is associated with all other parts.” He also makes a few remarks about Huyghens.]

Distinguished Sir,—For the encouragement to pursue my speculations given me by yourself and the distinguished R. Boyle, I return you my best thanks. I proceed as far as my slender abilities will allow me, with full confidence in your aid and kindness. When you ask me my opinion on the question raised concerning our knowledge of the means, whereby each part of nature agrees with its whole, and the manner in which it is associated with the remaining parts, I presume you are asking for the reasons which induce us to believe, that each part of nature agrees with its whole, and is associated with the remaining parts. For as to the means whereby the parts are really associated, and each part agrees with its whole, I told you in my former letter that I am in ignorance. To answer such a question, we should have to know the whole of nature and its several parts. I will therefore endeavor to show the reason, which led me to make the statement; but I will premise that I do not attribute to nature either beauty or deformity, order or confusion. Only in relation to our imagination can things be called beautiful or deformed, ordered or confused.

By the association of parts, then, I merely mean that the laws or nature of one part adapt themselves to the laws or nature of another part, so as to cause the least possible inconsistency. As to the whole and the parts, I mean that a given number of things are parts of a whole, in so far as the nature of each of them is adapted to the nature of the rest, so that they all, as far as possible, agree together. On the other hand, in so far as they do not agree, each of them forms, in our mind, a separate idea, and is to that extent considered as a whole, not as a part. For instance, when the parts of lymph, chyle, etc., combine, according to the proportion of the figure and size of each, so as to evidently unite, and form one fluid, the chyle, lymph, etc., considered under this aspect, are part of the blood; but, in so far as we consider the particles of lymph as differing in figure and size from the particles of chyle, we shall consider each of the two as a whole, not as a part.

Let us imagine, with your permission, a little worm, living in the blood, able to distinguish by sight the particles of blood, lymph, etc., and to reflect on the manner in which each particle, on meeting with another particle, either is repulsed or communicates a portion of its own motion. This little worm would live in the blood, in the same way as we live in a part of the universe, and would consider each particle of blood, not as a part, but as a whole. He would be unable to determine how all the parts are modified by the general nature of blood, and are compelled by it to adapt themselves, so as to stand in a fixed relation to one another. For, if we imagine that there are no causes external to the blood, which could communicate fresh movements to it, nor any space beyond the blood, nor any bodies whereto the particles of blood could communicate their motion, it is certain that the blood would always remain in the same state, and its particles would undergo no modifications, save those which may be conceived as arising from the relations of motion existing between the lymph, the chyle, etc. The blood would then always have to be considered as a whole, not as a part. But, as there exist, as a matter of fact, very many causes which modify, in a given manner, the nature of the blood, and are, in turn, modified thereby, it follows that other motions and other relations arise in the blood, springing not from the mutual relations of its parts only, but from the mutual relations between the blood as a whole and external causes. Thus the blood comes to be regarded as a part, not as a whole. So much for the whole and the part.

All natural bodies can and ought to be considered in the same way as we have here considered the blood, for all bodies are surrounded by others, and are mutually determined to exist and operate in a fixed and definite proportion, while the relations between motion and rest in the sum total of them, that is, in the whole universe, remain unchanged. Hence it follows that each body, in so far as it exists as modified in a particular manner, must be considered as a part of the whole universe, as agreeing with the whole, and associated with the remaining parts. As the nature of the universe is not limited, like the nature of blood, but is absolutely infinite, its parts are by this nature of infinite power infinitely modified, and compelled to undergo infinite variations. But, in respect to substance, I conceive that each part has a more close union with its whole. For, as I said in my first letter (addressed to you while I was still at Rhijnsburg), substance being infinite in its nature,† it follows, as I endeavored to show that each part belongs to the nature of substance, and without it, can neither be nor be conceived.

You see, therefore, how and why I think that the human body is a part of nature. As regards the human mind, I believe that it also is a part of nature; for I maintain that there exists in nature an infinite power of thinking, which, in so far as it is infinite, contains subjectively the whole of nature, and its thoughts proceed in the same manner as nature—that is, in the sphere of ideas. Further, I take the human mind to be identical with this said power, not in so far as it is infinite and perceives the whole nature, but in so far as it is finite, and perceives only the human body; in this manner, I maintain that the human mind is a part of an infinite understanding.

But to explain, and accurately prove, all these and kindred questions, would take too long; and I do not think you expect as much of me at present. I am afraid that I may have mistaken your meaning, and given an answer to a different question from that which you asked. Please inform me on this point.

You write in your last letter, that I hinted that nearly all the Cartesian laws of motion are false. What I said was, if I remember rightly, that Huyghens think so; I myself do not impeach any of the laws except the sixth, concerning which I think Huyghens is also in error. I ask you at the same time to communicate to me the experiment made according to that hypothesis in your Royal Society; as you have not replied, I infer that you are not at liberty to do so. The above-mentioned Huyghens is entirely occupied in polishing lenses. He has fitted up for the purpose a handsome workshop, in which he can also construct molds. What will be the result I know not, nor, to speak the truth, do I greatly care. Experience has sufficiently taught me, that the free hand is better and more sure than any machine for polishing spherical molds. I can tell you nothing certain as yet about the success of the clocks or the date of Huyghens’s journey to France.

Spinoza to Oldenburg.

[Spinoza relates his journey to Amsterdam for the purpose of publishing his “Ethics”; he was deterred by the dissuasions of theologians and Cartesians. He hopes that Oldenburg will inform him of some of the objections to the “Tractatus Theologico-Politicus,” made by learned men, so that they may be answered in notes.]

Distinguished and Illustrious Sir,—When I received your letter of the 22nd July, I had set out to Amsterdam for the purpose of publishing the book I had mentioned to you. While I was negotiating, a rumor gained currency that I had in the press a book concerning God, wherein I endeavored to show that there is no God. This report was believed by many. Hence certain theologians, perhaps the authors of the rumor, took occasion to complain of me before the prince and the magistrates; moreover, the stupid Cartesians, being suspected of favoring me, endeavored to remove the aspersion by abusing everywhere my opinions and writings, a course which they still pursue. When I became aware of this through trustworthy men, who also assured me that the theologians were everywhere lying in wait for me, I determined to put off publishing till I saw how things were going, and I proposed to inform you of my intentions. But matters seem to get worse and worse, and I am still uncertain what to do. Meanwhile I do not like to delay any longer answering your letter. I will first thank you heartily for your friendly warning, which I should be glad to have further explained, so that I may know, which are the doctrines which seem to you to be aimed against the practice of religion and virtue. If principles agree with reason, they are, I take it, also most serviceable to virtue. Further, if it be not troubling you too much I beg you to point out the passages in the “Tractatus Theologico-Politicus” which are objected to by the learned, for I want to illustrate that treatise with notes, and to remove if possible the prejudices conceived against it. Farewell.

Spinoza to Oldenburg.

Distinguished Sir,—I received on Saturday last your very short letter dated 15th Nov. In it you merely indicate the points in the theological treatise, which have given pain to readers, whereas I had hoped to learn from it, what were the opinions which militated against the practice of religious virtue, and which you formerly mentioned. However, I will speak on the three subjects on which you desire me to disclose my sentiments, and tell you, first, that my opinion concerning God differs widely from that which is ordinarily defended by modern Christians. For I hold that God is of all things the cause immanent, as the phrase is, not transient. I say that all things are in God and move in God, thus agreeing with Paul, and, perhaps, with all the ancient philosophers, though the phraseology may be different; I will even venture to affirm that I agree with all the ancient Hebrews, in so far as one may judge from their traditions, though these are in many ways corrupted. The supposition of some, that I endeavor to prove in the “Tractatus Theologico-Politicus” the unity of God and Nature (meaning by the latter a certain mass or corporeal matter), is wholly erroneous.

As regards miracles, I am of opinion that the revelation of God can only be established by the wisdom of the doctrine, not by miracles, or in other words, by ignorance. This I have shown at sufficient length in Chapter VI. concerning miracles. I will here only add, that I make this chief distinction between religion and superstition, that the latter is founded on ignorance, the former on knowledge; this, I take it, is the reason why Christians are distinguished from the rest of the world, not by faith, nor by charity, nor by the other fruits of the Holy Spirit, but solely by their opinions, inasmuch as they defend their cause, like everyone else, by miracles, that is, by ignorance, which is the source of all malice; thus they turn a faith, which may be true, into superstition. Lastly, in order to disclose my opinions on the third point, I will tell you that I do not think it necessary for salvation to know Christ according to the flesh: but with regard to the Eternal Son of God, that is, the Eternal Wisdom of God, which has manifested itself in all things and especially in the human mind, and above all in Christ Jesus, the case is far otherwise. For without this no one can come to a state of blessedness, inasmuch as it alone teaches, what is true or false, good or evil. And, inasmuch as this wisdom was made especially manifest through Jesus Christ, as I have said, his disciples preached it, in so far as it was revealed to them through him, and thus showed that they could rejoice in that spirit of Christ more than the rest of mankind. The doctrines added by certain churches, such as that God took upon himself human nature, I have expressly said that I do not understand; in fact, to speak the truth, they seem to me no less absurd than would a statement, that a circle had taken upon itself the nature of a square. This I think will be sufficient explanation of my opinions concerning the three points mentioned. Whether it will be satisfactory to Christians you will know better than I. Farewell.

Spinoza to Oldenburg.

[Spinoza expounds to Oldenburg his views on fate and necessity, discriminates between miracles and ignorance, takes the resurrection of Christ as spiritual, and deprecates attributing to the sacred writers western modes of speech.]

Distinguished Sir:—At last I see what it was that you begged me not to publish. However; as it forms the chief foundation of everything in the treatise which I intended to bring out, I should like briefly to explain here in what sense I assert that a fatal necessity presides over all things and actions. God I in no wise subject to fate: I conceive that all things follow with inevitable necessity from the nature of God, in the same way as every one conceives that it follows from God’s nature that God understands himself. This latter consequence all admit to follow necessarily from the divine nature, yet no one conceives that God is under the compulsion of any fate, but that he understands himself quite freely, though necessarily.

Further, this inevitable necessity in things does away neither with divine nor human laws. The principles of morality, whether they receive from God himself the form of laws or institutions, or whether they do not, are still divine and salutary; whether we receive the good, which flows from virtue and the divine love, as from God in the capacity of a judge, or as from the necessity of the divine nature, it will in either case be equally desirable; on the other hand, the evils following from wicked actions and passions are not less to be feared because they are necessary consequences. Lastly, in our actions, whether they be necessary or contingent, we are led by hope and fear.

Men are only without excuse before God, because they are in God’s power, as clay is in the hands of the potter, who from the same lump makes vessels, some to honor, some to dishonor. If you will reflect a little on this, you will, I doubt not, easily be able to reply to any objections which may be urged against my opinion, as many of my friends have already done.

I have taken miracles and ignorance as equivalent terms, because those, who endeavor to establish God’s existence and the truth of religion by means of miracles, seek to prove the obscure by what is more obscure and completely unknown, thus introducing a new sort of argument, the reduction, not to the impossible, as the phrase is, but to ignorance. But, if I mistake not, I have sufficiently explained my opinion on miracles in the “Theologico-Political” treatise. I will only add here, that if you will reflect on the facts; that Christ did not appear to the council, nor to Pilate, nor to any unbeliever, but only to the faithful; also that God has neither right hand nor left, but is by his essence not in a particular spot, but everywhere; that matter is everywhere the same; that God does not manifest himself in the imaginary space supposed to be outside the world; and lastly, that the frame of the human body is kept within due limits solely by the weight of the air; you will readily see that this apparition of Christ is not unlike that wherewith God appeared to Abraham, when the latter saw men whom he invited to dine with him. But, you will say, all the Apostles thoroughly believed, that Christ rose from the dead and really ascended to heaven: I do not deny it. Abraham, too, believed that God had dined with him, and all the Israelites believed that God descended, surrounded with fire, from heaven to Mount Sinai, and there spoke directly with them; whereas, these apparitions or revelations, and many others like them, were adapted to the understanding and opinions of those men, to whom God wished thereby to reveal his will. I therefore conclude, that the resurrection of Christ from the dead was in reality spiritual, and that to the faithful alone, according to their understanding, it was revealed that Christ was endowed with eternity, and had risen from the dead (using DEAD in the sense in which Christ said, “let the dead bury their dead”*), giving by his life and death a matchless example of holiness. Moreover, he to this extent raises his disciples from the dead, in so far as they follow the example of his own life and death. It would not be difficult to explain the whole Gospel doctrine on this hypothesis. Nay, 1 Cor. ch. xv. cannot be explained on any other, nor can Paul’s arguments be understood: if we follow the common interpretation, they appear weak and can easily be refuted: not to mention the fact, that Christians interpret spiritually all those doctrines which the Jews accepted literally. I join with you in acknowledging human weakness. But on the other hand, I venture to ask you whether we “human pigmies” possess sufficient knowledge of nature to be able to lay down the limits of its force and power, or to say that a given thing surpasses that power? No one could go so far without arrogance. We may, therefore, without presumption explain miracles as far as possible by natural causes. When we cannot explain them, nor even prove their impossibility, we may well suspend our judgment about them, and establish religion, as I have said, solely by the wisdom of its doctrines. You think that the texts in John’s Gospel and in Hebrews are inconsistent with what I advance, because you measure oriental phrases by the standards of European speech; though John wrote his gospel in Greek, he wrote it as a Hebrew. However this may be, do you believe, when Scripture says that God manifested himself in a cloud, or that he dwelt in the tabernacle, or the temple, that God actually assumed the nature of a cloud, a tabernacle, or a temple? Yet the utmost that Christ says of himself, that he is the Temple of God,* because, as I said before, God had specially manifested himself in Christ. John, wishing to express the same truth more forcibly, said that “the Word was made flesh.” But I have said enough on the subject.

Spinoza to Oldenburg.

[Spinoza again treats of fatalism. He repeats that he accepts Christ’s passion, death, and burial literally, but his resurrection spiritually.]

Distinguished Sir,—When I said in my former letter that we are inexcusable; because we are in the power of God, like clay in the hands of the potter, I meant to be understood in the sense that no one can bring a complaint against God for having given him a weak nature, or infirm spirit. A circle might as well complain to God of not being endowed with the properties of a sphere, or a child who is tortured, say, with stone, for not being given a healthy body, as a man of feeble spirit, because God has denied to him fortitude, and the true knowledge and love of the Deity, or because he is endowed with so weak a nature that he cannot check or moderate his desires. For the nature of each thing is only competent to do that which follows necessarily from its given cause. That every man cannot be brave, and that we can no more command for ourselves a healthy body than a healthy mind, nobody can deny, without giving the lie to experience, as well as to reason. “But,” you urge, “if men sin by nature, they are excusable”; but you do not state the conclusion you draw, whether that God cannot be angry with them or that they are worthy of blessedness—that is, of the knowledge and love of God. If you say the former, I fully admit that God cannot be angry, and that all things are done in accordance with his will; but I deny that all men ought, therefore, to be blessed—men may be excusable, and, nevertheless, be without blessedness and afflicted in many ways. A horse is excusable for being a horse and not a man; but, nevertheless, he must needs be a horse and not a man. He who goes mad from the bite of a dog is excusable, yet he is rightly suffocated. Lastly, he who cannot govern his desires, and keep them in check with the fear of the laws, though his weakness may be excusable, yet he cannot enjoy with contentment the knowledge and love of God, but necessarily perishes. I do not think it necessary here to remind you, that Scripture, when it says that God is angry with sinners, and that he is a Judge who takes cognizance of human actions, passes sentence on them, and judges them, is speaking humanely, and in a way adapted to the received opinion of the masses, inasmuch as its purpose is not to teach philosophy, nor to render men wise, but to make them obedient.

How, by taking miracles and ignorance as equivalent terms, I reduce God’s power and man’s knowledge within the same limits, I am unable to discern.

For the rest, I accept Christ’s passion, death and burial literally, as you do, but his resurrection I understand allegorically. I admit, that it is related by the Evangelists in such detail, that we cannot deny that they themselves believed Christ’s body to have risen from the dead and ascended to heaven, in order to sit at the right hand of God, or that they believed that Christ might have been seen by unbelievers, if they had happened to be at hand, in the places where he appeared to his Disciples; but in these matters they might, without injury to Gospel teaching, have been deceived, as was the case with other prophets mentioned in my last letter. But Paul, to whom Christ afterward appeared, rejoices that he knew Christ not after the flesh, but after the spirit.* Farewell, honorable Sir, and believe me yours in all affection and zeal.

Spinoza to Simon De Vries.

[Spinoza deprecates his correspondent’s jealousy of Albert Burgh; and answers that distinction must be made between different kinds of definitions. He explains his opinions more precisely.]

Respected Friend,—I have received your long wished-for letter, for which, and for your affection toward me, I heartily thank you. Your long absence has been no less grievous to me than to you; yet in the meantime I rejoice that my trifling studies are of profit to you and our friends. For thus while you are away, I in my absence speak to you. You need not envy my fellow-lodger. There is no one who is more displeasing to me, nor against whom I have been more anxiously on my guard; and therefore I would have you and all my acquaintance warned not to communicate my opinions to him, except when he has come to maturer years. So far he is too childish and inconstant, and is fonder of novelty than of truth. But I hope, that in a few years he will amend these childish faults. Indeed I am almost sure of it, as far as I can judge from his nature. And so his temperament bids me like him.

As for the questions propounded in your club, which is wisely enough ordered, I see that your difficulties arise from not distinguishing between kinds of definition: that is, between a definition serving to explain a thing, of which the essence only is sought and in question, and a definition which is put forward only for purposes of inquiry. The former having a definite object ought to be true, the latter need not. For instance, if some one asks me for a description of Solomon’s temple, I am bound to give him a true description, unless I want to talk nonsense with him. But if I have constructed, in my mind, a temple which I desire to build, and infer from the description of it that I must buy such and such a site and so many thousand stones and other materials, will any sane person tell me that I have drawn a wrong conclusion because my definition is possibly untrue? or will anyone ask me to prove my definition? Such a person would simply be telling me, that I had not conceived that which I had conceived, or be requiring me to prove, that I had conceived that which I had conceived; in fact, evidently trifling. Hence a definition either explains a thing, in so far as it is external to the intellect, in which case it ought to be true and only to differ from a proposition or an axiom in being concerned merely with the essences of things, or the modifications of things, whereas the latter has a wider scope and extends also to eternal truths. Or else it explains a thing, as it is conceived or can be conceived by us; and then it differs from an axiom or proposition, inasmuch as it only requires to be conceived absolutely, and not like an axiom as true. Hence a bad definition is one which is not conceived. To explain my meaning, I will take Borel’s example—a man saying that two straight lines enclosing a space shall be called “figurals.” If the man means by a straight line the same as the rest of the world means by a curved line, his definition is good (for by the definition would be meant some such figure as (), or the like); so long as he does not afterward mean a square or other kind of figure. But, if he attaches the ordinary meaning to the words straight line, the thing is evidently inconceivable, and therefore there is no definition. These considerations are plainly confused by Borel, to whose opinion you incline. I give another example, the one you cite at the end of your letter. If I say that each substance has only one attribute, this is an unsupported statement and needs proof. But, if I say that I mean by substance that which consists in only one attribute, the definition will be good, so long as entities consisting of several attributes are afterward styled by some name other than substance. When you say that I do not prove, that substance (or being) may have several attributes, you do not perhaps pay attention to the proofs given. I adduced two: First, “that nothing is plainer to us, than that every being may be conceived by us under some attribute, and that the more reality or essence a given being has, the more attributes may be attributed to it. Hence a being absolutely infinite must be defined, etc.” Secondly, and I think this is the stronger proof of the two, “the more attributes I assign to any being, the more am I compelled to assign to it existence;” in other words, the more I conceive it as true. The contrary would evidently result if I were feigning a chimera or some such being.

Your remark that you cannot conceive thought except as consisting in ideas, because, when ideas are removed, thought is annihilated, springs, I think, from the fact that while you a thinking thing, do as you say, you abstract all your thoughts and conceptions. It is no marvel that, when you have abstracted all your thoughts and conceptions, you have nothing left for thinking with. On the general subject, I think I have shown sufficiently clearly and plainly, that the intellect, although infinite, belongs to nature regarded as passive rather than nature regarded as active (ad naturam naturatam, non vero ad naturam naturantem).

However, I do not see how this helps toward understanding the third definition, nor what difficulty the latter presents. It runs, if I mistake not, as follows: “By substance I mean that, which is in itself and is conceived through itself; that is, of which the conception does not involve the conception of anything else. By attribute I mean the same thing; except that it is called attribute with respect to the understanding, which attributes to substance the particular nature aforesaid.” This definition, I repeat, explains with sufficient clearness what I wish to signify by substance or attribute. You desire, though there is no need, that I should illustrate by an example, how one and the same thing can be stamped with two names. In order not to seem miserly, I will give you two. First, I say that by Israel is meant the third patriarch; I mean the same by Jacob, the name Jacob being given, because the patriarch in question had caught hold of the heel of his brother. Secondly, by a colorless surface I mean a surface, which reflects all rays of light without altering them. I mean the same by a white surface, with this difference, that a surface is called white in reference to a man looking at it, etc.

Spinoza to Simon De Vries.

[Spinoza, in answer to a letter from De Vries now lost, speaks of the experience necessary for proving a definition, and also of eternal truths.]

Respected Friend,—You ask me if we have need of experience, in order to know whether the definition of a given attribute is true. To this I answer that we never need experience, except in cases when the existence of the thing cannot be inferred from its definition, as, for instance, the existence of modes (which cannot be inferred from their definition); experience is not needed, when the existence of the things in question is not distinguished from their essence, and is therefore inferred from their definition. This can never be taught us by any experience, for experience does not teach us any essences of things; the utmost it can do is to set our mind thinking about definite essences only. Wherefore, when the existence of attributes does not differ from their essence, no experience is capable of attaining it for us.

To your further question, whether things and their modifications are eternal truths, I answer; Certainly. If you ask me, why I do not call them eternal truths, I answer, in order to distinguish them, in accordance with general usage, from those propositions, which do not make manifest any particular thing or modification of a thing; for example, NOTHING COMES FROM NOTHING. These and such like propositions are, I repeat, called eternal truths simply, the meaning merely being, that they have no standpoint external to the mind, etc.

Spinoza to Lewis Meyer

Dearest Friend,—I have received two letters from you, one dated Jan. 11, delivered to me by our friend, N. N., the other dated March 26, sent by some unknown friend to Leyden. They were both most welcome to me, especially as I gathered from them, that all goes well with you, and that you are often mindful of me. I also owe and repay you the warmest thanks for the courtesy and consideration, with which you have always been kind enough to treat me: I hope you will believe, that I am in no less degree devoted to you, as, when occasion offers, I will always endeavor to prove, as far as my poor powers will admit. As a first proof, I will do my best to answer the questions you ask in your letters. You request me to tell you, what I think about the Infinite; I will most readily do so.

Everyone regards the question of the Infinite as most difficult, if not insoluble, through not making a distinction between that which must be infinite from its very nature, or in virtue of its definition, and that which has no limits, not in virtue of its essence, but in virtue of its cause; and also through not distinguishing between that which is called infinite, because it has no limits, and that, of which the parts cannot be equalled or expressed by any number, though the greatest and least magnitude of the whole may be known; and, lastly, through not distinguishing between that, which can be understood but not imagined, and that which can also be imagined. If these distinctions, I repeat, had been attended to, inquirers would not have been overwhelmed with such a vast crowd of difficulties. They would then clearly have understood, what kind of infinite is indivisible and possesses no parts; and what kind, on the other hand, may be divided without involving a contradiction in terms. They would further have understood, what kind of infinite may, without solecism, be conceived greater than another infinite, and what kind cannot be so conceived. All this will plainly appear from what I am about to say.

However, I will first briefly explain the terms SUBSTANCE, MODE, ETERNITY, and DURATION.

The points to be noted concerning substance are these: First, that existence appertains to its essence; in other words, that solely from its essence and definition its existence follows. This, if I remember rightly, I have already proved to you by word of mouth, without the aid of any other propositions. Secondly, as a consequence of the above, that substance is not manifold, but single: there cannot be two of the same nature. Thirdly, every substance must be conceived as infinite.

The modifications of substance I call MODES. Their definition, in so far as it is not identical with that of substance, cannot involve any existence. Hence, though they exist, we can conceive them as non-existent. From this it follows, that, when we are regarding only the essence of modes, and not the order of the whole of nature, we cannot conclude from their present existence, that they will exist or not exist in the future, or that they have existed or not existed in the past; whence it is abundantly clear, that we conceive the existence of substance as entirely different from the existence of modes. From this difference arises the distinction between ETERNITY and DURATION. DURATION is only applicable to the existence of modes; ETERNITY is applicable to the existence of substance, that is, the infinite faculty of existence or being (infinitum existendi sive—invitâ Latinitate—essendi fruitionem).

From what has been said it is quite clear that when, as is most often the case, we are regarding only the essence of modes and not the order of nature, we may freely limit the existence and duration of modes without destroying the conception we have formed of them; we may conceive them as greater or less, or may divide them into parts. Eternity and substance, being only conceivable as infinite, cannot be thus treated without our conception of them being destroyed. Wherefore it is mere foolishness, or even insanity, to say that extended substance is made up of parts or bodies really distinct from one another. It is as though one should attempt by the aggregation and addition of many circles to make up a square, or a triangle, or something of totally different essence. Wherefore the whole heap of arguments, by which philosophers commonly endeavor to show that extended substance is finite, falls to the ground by its own weight. For all such persons suppose, that corporeal substance is made up of parts. In the same way, others who have persuaded themselves that a line is made up of points, have been able to discover many arguments to show that a line is not infinitely divisible. If you ask, why we are by nature so prone to attempt to divide extended substance, I answer, that quantity is conceived by us in two ways, namely, by abstraction or superficially, as we imagine it by the aid of the senses, or as substance, which can only be accomplished through the understanding. So that, if we regard quantity as it exists in the imagination (and this is the more frequent and easy method), it will be found to be divisible, finite, composed of parts, and manifold. But, if we regard it as it is in the understanding, and the thing be conceived as it is in itself (which is very difficult), it will then, as I have sufficiently shown you before, be found to be infinite, indivisible, and single.

Again, from the fact that we can limit duration and quantity at our pleasure, when we conceive the latter abstractedly as apart from substance, and separate the former from the manner whereby it flows from things eternal, there arise TIME and MEASURE; TIME for the purpose of limiting duration, MEASURE for the purpose of limiting quantity, so that we may, as far as is possible, the more readily imagine them. Further, inasmuch as we separate the modifications of substance from substance itself, and reduce them to classes, so that we may, as far as is possible, the more readily imagine them, there arises NUMBER, whereby we limit them. Whence it is clearly to be seen, that measure, time, and number, are merely modes of thinking, or, rather, of imagining. It is not to be wondered at, therefore, that all who have endeavored to understand the course of nature, by means of such notions, and without fully understanding even them, have entangled themselves so wondrously, that they have at last only been able to extricate themselves by breaking through every rule and admitting absurdities even of the grossest kind. For there are many things which cannot be conceived through the imagination but only through the understanding, for instance, substance, eternity, and the like; thus, if any one tries to explain such things by means of conceptions which are mere aids to the imagination, he is simply assisting his imagination to run away with him. Nor can even the modes of substance, ever be rightly understood, if we confuse them with entities of the kind mentioned, mere aids of the reason or imagination. In so doing we separate them from substance, and the mode of their derivation from eternity, without which they can never be rightly understood. To make the matter yet more clear, take the following example: when a man conceives of duration abstractedly, and, confusing it with time, begins to divide it into parts, he will never be able to understand how an hour, for instance, can elapse. For in order that an hour should elapse, it is necessary that its half should elapse first, and afterward half of the remainder, and again half of the half of the remainder, and if you go on thus to infinity, subtracting the half of the residue, you will never be able to arrive at the end of the hour. Wherefore many, who are not accustomed to distinguish abstractions from realities, have ventured to assert that duration is made up of instants, and so in wishing to avoid Charybdis have fallen into Scylla. It is the same thing to make up duration out of instants, as it is to make number simply by adding up naughts.

Further, as it is evident from what has been said, that neither number, nor measure, nor time, being mere aids to the imagination, can be infinite (for, otherwise, number would not be number, nor measure measure, nor time time); it is hence abundantly evident, why many who confuse these three abstractions with realities, through being ignorant of the true nature of things, have actually denied the Infinite.

The wretchedness of their reasoning may be judged by mathematicians, who have never allowed themselves to be delayed a moment by arguments of this sort, in the case of things which they clearly and distinctly perceive. For not only have they come across many things, which cannot be expressed by number (thus showing the inadequacy of number for determining all things); but also they have found many things, which cannot be equalled by any number, but surpass every possible number. But they infer hence, that such things surpass enumeration, not because of the multitude of their component parts, but because their nature cannot, without manifest contradiction, be expressed in terms of number. As, for instance, in the case of two circles, non-concentric, whereof one incloses the other, no number can express the inequalities of distance which exist between the two circles, nor all the variations which matter in motion in the intervening space may undergo. This conclusion is not based on the excessive size of the intervening space. However small a portion of it we take, the inequalities of this small portion will surpass all numerical expression. Nor, again, is the conclusion based on the fact, as in other cases, that we do not know the maximum and the minimum of the said space. It springs simply from the fact, that the nature of the space between two non-concentric circles cannot be expressed in number. Therefore, he who would assign a numerical equivalent for the inequalities in question, would be bound, at the same time, to bring about that a circle should not be a circle.

The same result would take place—to return to my subject—if one were to wish to determine all the motions undergone by matter up to the present, by reducing them and their duration to a certain number and time. This would be the same as an attempt to deprive corporeal substance, which we cannot conceive except as existent, of its modifications, and to bring about that it should not possess the nature which it does possess. All this I could clearly demonstrate here, together with many other points touched on in this latter, but I deem it superfluous.

From all that has been said, it is abundantly evident that certain things are in their nature infinite, and can by no means be conceived as finite; whereas there are other things, infinite in virtue of the cause from which they are derived, which can, when conceived abstractedly, be divided into parts, and regarded as finite. Lastly, there are some which are called infinite or, if you prefer, indefinite, because they cannot be expressed in number, which may yet be conceived as greater or less. It does not follow that such are equal, because they are alike incapable of numerical expression. This is plain enough, from the example given, and many others.

Lastly, I have put briefly before you the causes of error and confusion, which have arisen concerning the question of the infinite. I have, if I mistake not, so explained them that no question concerning the infinite remains untreated, or cannot readily be solved from what I have said; wherefore, I do not think it worth while to detain you longer on the matter.

But I should like it first to be observed here, that the later Peripatetics have, I think, misunderstood the proof given by the Ancients who sought to demonstrate the existence of God. This, as I find it in a certain Jew named Rabbi Ghasdai, runs as follows: “If there be an infinite series of causes, all things which are, are caused. But nothing which is caused can exist necessarily in virtue of its own nature. Therefore, there is nothing in nature, to whose essence existence necessarily belongs. But this is absurd. Therefore, the premise is absurd also.” Hence the force of the argument lies not in the impossibility of an actual infinite or an infinite series of causes; but only in the absurdity of the assumption that things, which do not necessarily exist by nature, are not conditioned for existence by a thing, which does by its own nature necessarily exist.

I would now pass on, for time presses, to your second letter: but I shall be able more conveniently to reply to its contents, when you are kind enough to pay me a visit. I therefore beg that you will come as soon as possible; the time for traveling is at hand. Enough. Farewell, and keep in remembrance,

Yours, etc.

Rhijinsburg, 20 April, 1663.

Spinoza to Lewis Meyer.

Dear Friend,—The preface you sent me by our friend De Vries, I now send back to you by the same hand. Some few things, as you will see, I have marked in the margin; but yet a few remain, which I have judged it better to mention to you by letter. First, where on page 4 you give the reader to know on what occasion I composed the first part; I would have you likewise explain there, or where you please, that I composed it within a fortnight. For when this is explained none will suppose the exposition to be so clear as that it cannot be bettered, and so they will not stick at obscurities in this and that phrase on which they may chance to stumble. Secondly, I would have you explain, that when I prove many points otherwise than they be proved by Descartes, ’tis not to amend Descartes, but the better to preserve my order, and not to multiply axioms overmuch: and that for this same reason I prove many things which by Descartes are barely alleged without any proof, and must needs add other matters which Descartes let alone. Lastly, I will earnestly beseech you, as my especial friend, to let be everything you have written toward the end against that creature, and wholly strike it out. And though many reasons determine me to this request, I will give but one. I would fain have all men readily believe that these matters are published for the common profit of the world, and that your sole motive in bringing out the book is the love of spreading the truth; and that it is accordingly all your study to make the work acceptable to all, to bid men, with all courtesy to the pursuit of genuine philosophy, and to consult their common advantage. Which every man will be ready to think when he sees that no one is attacked, nor anything advanced where any man can find the least offense. Notwithstanding, if afterward the person you know of, or any other, be minded to display his ill-will, then you may portray his life and character, and gain applause by it. So I ask that you will not refuse to be patient thus far, and suffer yourself to be entreated, and believe me wholly bounden to you, and

Yours with all affection

B. de Spinoza.

Voorburg, Aug. 3, 1663.

Our friend De Vries had promised to take this with him; but seeing he knows not when he will return to you, I send it by another hand.

Along with this I send you part of the scholium to Prop. xxvii. Part II. where page 75 begins, that you may hand it to the printer to be reprinted. The matter I send you must of necessity be reprinted, and fourteen or fifteen lines added, which may easily be inserted.

Spinoza to Peter Balling.

[Concerning omens and phantoms. The mind may have a confused presentiment of the future.]

Beloved Friend,—Your last letter, written, if I mistake not, on the 26th of last month, has duly reached me. It caused me no small sorrow and solicitude, though the feeling sensibly diminished when I reflected on the good sense and fortitude, with which you have known how to despise the evils of fortune, or rather of opinion, at a time when they most bitterly assailed you. Yet my anxiety increases daily; I therefore beg and implore you by the claims of our friendship, that you will rouse yourself to write me a long letter. With regard to OMENS, of which you make mention in telling me that, while your child was still healthy and strong, you heard groans like those he uttered when he was ill and shortly afterward died, I should judge that these were not real groans, but only the effect of your imagination; for you say that, when you got up and composed yourself to listen, you did not hear them so clearly either as before or as afterward, when you had fallen asleep again. This, I think, shows that the groans were purely due to the imagination, which, when it was unfettered and free, could imagine groans more forcibly and vividly than when you sat up in order to listen in a particular direction. I think I can both illustrate and confirm what I say by another occurrence, which befell me at Rhijnsburg last winter. When one morning, after the day had dawned, I woke up from a very unpleasant dream, the images, which had presented themselves to me in sleep, remained before my eyes just as vividly as though the things had been real, especially the image of a certain black and leprous Brazilian whom I had never seen before. This image disappeared for the most part when, in order to divert my thoughts, I cast my eyes on a book, or something else. But, as soon as I lifted my eyes again without fixing my attention on any particular object, the same image of this same negro appeared with the same vividness again and again, until the head of it gradually vanished. I say that the same thing which occurred with regard to my inward sense of sight, occurred with your hearing; but as the causes were very different, your case was an omen and mine was not. The matter may be clearly grasped by means of what I am about to say. The effects of the imagination arise either from bodily or mental causes. I will proceed to prove this, in order not to be too long, solely from experience. We know that fevers and other bodily ailments are the causes of delirium, and that persons of stubborn disposition imagine nothing but quarrels, brawls, slaughterings, and the like. We also see that the imagination is to a certain extent determined by the character of the disposition, for, as we know by experience, it follows in the tracks of the understanding in every respect, and arranges its images and words, just as the understanding arranges its demonstrations and connects one with another; so that we are hardly at all able to say what will not serve the imagination as a basis for some image or other. This being so, I say that no effects of imagination springing from physical causes can ever be omens of future events; inasmuch as their causes do not involve any future events. But the effects of imagination, or images originating in the mental disposition, may be omens of some future event; inasmuch as the mind may have a confused presentiment of the future. It may, therefore, imagine a future event as forcibly and vividly, as though it were present; for instance a father (to take an example resembling your own) loves his child so much that he and the beloved child are, as it were, one and the same. And since (like that which I demonstrated on another occasion) there must necessarily exist in thought the idea of the essence of the child’s states and their results, and since the father, through his union with his child, is a part of the said child, the soul of the father must necessarily participate in the ideal essence of the child and his states, and in their results, as I have shown at greater length elsewhere.

Again, as the soul of the father participates ideally in the consequences of his child’s essence, he may (as I have said) sometimes imagine some of the said consequences as vividly as if they were present with him, provided that the following conditions are fulfilled: I. If the occurrence in his son’s career be remarkable. II. If it be capable of being readily imagined. III. If the time of its happening be not too remote. IV. If his body be sound, in respect not only of health but of freedom from every care or business which could outwardly trouble the senses. It may also assist the result, if we think of something which generally stimulates similar ideas. For instance, if while we are talking with this or that man we hear groans, it will generally happen that, when we think of the man again, the groans heard when we spoke with him will recur to our mind. This, dear friend, is my opinion on the question you ask me. I have, I confess, been very brief, but I have furnished you with material for writing to me on the first opportunity, etc.

Voorburg, 20 July, 1664.

Spinoza to Blyenbergh.

[Spinoza answers with his usual courtesy the question propounded by Blyenbergh.]

Unknown Friend,—I received, at Schiedam, on the 26th of December, your letter dated the 12th of December, inclosed in another written on the 24th of the same month. I gather from it your fervent love of truth, and your making it the aim of all your studies. This compelled me, though by no means otherwise unwilling, not only to grant your petition by answering all the questions you have sent, or may in future send, to the best of my ability, but also to impart to you everything in my power, which can conduce to further knowledge and sincere friendship. So far as in me lies, I value, above all other things out of my own control, the joining hands of friendship with men who are sincere lovers of truth. I believe that nothing in the world, of things outside our own control, brings more peace than the possibility of affectionate intercourse with such men; it is just as impossible that the love we bear them can be disturbed (inasmuch as it is founded on the desire each feels for the knowledge of truth), as that truth once perceived should not be assented to. It is, moreover, the highest and most pleasing source of happiness derivable from things not under our own control. Nothing save truth has power closely to unite different feelings and dispositions. I say nothing of the very great advantages which it brings, lest I should detain you too long on a subject which, doubtless, you know already. I have said thus much, in order to show you better how gladly I shall embrace this and any future opportunity of serving you.

In order to make the best of the present opportunity, I will at once proceed to answer your question. This seems to turn on the point “that it seems to be clear, not only from God’s providence, which is identical with his will, but also from God’s co-operation and continuous creation of things, either that there are no such things as sin or evil, or that God directly brings sin and evil to pass.” You do not, however, explain what you mean by evil. As far as one may judge from the example you give in the predetermined act of volition of Adam, you seem to mean by evil the actual exercise of volition, in so far as it is conceived as predetermined in a particular way, or in so far as it is repugnant to the command of God. Hence you conclude (and I agree with you if this be what you mean) that it is absurd to adopt either alternative, either that God brings to pass anything contrary to his own will, or that what is contrary to God’s will can be good.

For my own part, I cannot admit that sin and evil have any positive existence, far less that anything can exist, or come to pass, contrary to the will of God. On the contrary, not only do I assert that sin has no positive existence, I also maintain that only in speaking improperly, or humanly, can we say that we sin against God, as in the expression that men offend God.

As to the first point, we know that whatsoever is, when considered in itself without regard to anything else, possesses perfection, extending in each thing as far as the limits of that thing’s essence: for essence is nothing else. I take for an illustration the design or determined will of Adam to eat the forbidden fruit. This design or determined will, considered in itself alone, includes perfection in so far as it expresses reality; hence it may be inferred that we can only conceive imperfection in things, when they are viewed in relation to other things possessing more reality: thus in Adam’s decision, so long as we view it by itself and do not compare it with other things more perfect or exhibiting a more perfect state, we can find no imperfection: nay, it may be compared with an infinity of other things far less perfect in this respect than itself, such as stones, stocks, etc. This, as a matter of fact, everyone grants. For we all admire in animals qualities which we regard with dislike and aversion in men, such as the pugnacity of bees, the jealousy of doves, etc.; these in human beings are despised but are nevertheless considered to enhance the value of animals. This being so, it follows that sin, which indicates nothing save imperfection, cannot consist in anything that expresses reality, as we see in the case of Adam’s decision and its execution.

Again, we cannot say that Adam’s will is at variance with the law of God, and that it is evil because it is displeasing to God; for besides the fact that grave imperfection would be imputed to God, if we say that anything happens contrary to his will, or that he desires anything which he does not obtain, or that his nature resembled that of his creatures in having sympathy with some things more than others; such an occurrence would be at complete variance with the nature of the divine will.

The will of God is identical with his intellect; hence the former can no more be contravened than the latter, in other words, anything which should come to pass against his will must be of a nature to be contrary to his intellect, such, for instance, as a round square. Hence the will or decision of Adam regarded in itself was neither evil nor, properly speaking, against the will of God: it follows that God may—or rather, for the reason you call attention to, must—be its cause; not in so far as it was evil, for the evil in it consisted in the loss of the previous state of being which it entailed on Adam, and it is certain that loss has no positive existence, and is only so spoken of in respect to our and not God’s understanding. The difficulty arises from the fact that we give one and the same definition to all the individuals of a genus, as for instance, all who have the outward appearance of men: we accordingly assume all things which are expressed by the same definition to be equally capable of attaining the highest perfection possible for the genus; when we find an individual whose actions are at variance with such perfection, we suppose him to be deprived of it, and to fall short of his nature. We should hardly act in this way, if we did not hark back to the definition and ascribe to the individual a nature in accordance with it. But as God does not know things through abstraction, or form general definitions of the kind above mentioned, and as things have no more reality than the divine understanding and power have put into them and actually endowed them with, it clearly follows that a state of privation can only be spoken of in relation to our intellect, not in relation to God.

Thus, as it seems to me, the difficulty is completely solved. However, in order to make the way still plainer, and remove every doubt, I deem it necessary to answer the two following difficulties: First, why Holy Scripture says that God wishes for the conversion of the wicked, and also why God forbade Adam to eat of the fruit when he had ordained the contrary? Secondly, that it seems to follow from what I have said, that the wicked, by their pride, avarice, and deeds of desperation, worship God in no less degree than the good do by their nobleness, patience, love, etc., inasmuch as both execute God’s will.

In answer to the first question, I observe that Scripture, being chiefly fitted for and beneficial to the multitude, speaks popularly after the fashion of men. For the multitude are incapable of grasping sublime conceptions. Hence I am persuaded that all matters, which God revealed to the prophets as necessary to salvation, are set down in the form of laws. With this understanding, the prophets invented whole parables, and represented God as a king and a lawgiver, because he had revealed the means of salvation and perdition, and was their cause; the means which were simply causes they styled laws and wrote them down as such; salvation and perdition, which are simply effects necessarily resulting from the aforesaid means, they described as reward and punishment; framing their doctrines more in accordance with such parables than with actual truth. They constantly speak of God as resembling a man, as sometimes angry, sometimes merciful, now desiring what is future, now jealous and suspicious, even as deceived by the devil; so that philosophers and all who are above the law, that is, who follow after virtue, not in obedience to law, but through love, because it is the most excellent of all things, must not be hindered by such expressions.

Thus the command given to Adam consisted solely in this, that God revealed to Adam, that eating of the fruit brought about death; as he reveals to us, through our natural faculties, that poison is deadly. If you ask, for what object did he make this revelation, I answer in order to render Adam to that extent more perfect in knowledge. Hence, to ask God why he had not bestowed on Adam a more perfect will, is just as absurd as to ask, why the circle has not been endowed with all the properties of a sphere. This follows clearly from what has been said, and I have also proved it in my “Principles of Cartesian Philosophy,” I. 15.

As to the second difficulty, it is true that the wicked execute after their manner the will of God: but they cannot, therefore, be in any respect compared with the good. The more perfection a thing has, the more does it participate in the Deity, and the more does it express perfection. Thus, as the good have incomparably more perfection than the bad, their virtue cannot be likened to the virtue of the wicked, inasmuch as the wicked lack the love of God, which proceeds from the knowledge of God, and by which alone we are, according to our human understanding, called the servants of God. The wicked, knowing not God, are but as instruments in the hand of the workman, serving unconsciously, and perishing in the using; the good, on the other hand, serve consciously, and in serving become more perfect.

This, Sir, is all I can now contribute to answering your question, and I have no higher wish than that it may satisfy you. But in case you still find any difficulty, I beg you to let me know of that also, to see if I may be able to remove it. You have nothing to fear on your side, but so long as you are not satisfied, I like nothing better than to be informed of your reasons, so that finally the truth may appear. I could have wished to write in the tongue in which I have been brought up. I should, perhaps, have been able to express my thoughts better. But be pleased to take it as it is, amend the mistakes yourself, and believe me,

Your sincere friend and servant.

Spinoza to Blyenbergh.

[Spinoza complains that Blyenbergh has misunderstood him: he sets forth his true meaning.]

Voorburg, 28 Jan., 1665.

Friend and Sir:—When I read your first letter, I thought that our opinions almost coincided. But from the second, which was delivered to me on the 21st of this month, I see that the matter stands far otherwise, for I perceive that we disagree, not only in remote inferences from first principles, but also in first principles themselves; so that I can hardly think that we can derive any mutual instruction from further correspondence. I see that no proof, though it be by the laws of proof most sound, has any weight with you, unless it agrees with the explanation, which either you yourself, or other theologians known to you, attribute to Holy Scripture. However, if you are convinced that God speaks more clearly and effectually through Holy Scripture than through the natural understanding, which he also has bestowed upon us, and with his divine wisdom keeps continually stable and uncorrupted, you have valid reasons for making your understanding bow before the opinions which you attribute to Holy Scripture; I myself could adopt no different course. For my own part, as I confess plainly, and without circumlocution, that I do not understand the Scriptures, though I have spent some years upon them, and also as I feel that when I have obtained a firm proof, I cannot fall into a state of doubt concerning it, I acquiesce entirely in what is commended to me by my understanding, without any suspicion that I am being deceived in the matter, or that Holy Scripture, though I do not search, could gainsay it: for “truth is not at variance with truth,” as I have already clearly shown in my appendix to “The Principles of Cartesian Philosophy” (I cannot give the precise reference, for I have not the book with me here in the country). But if in any instance I found that a result obtained through my natural understanding was false, I should reckon myself fortunate, for I enjoy life, and try to spend it not in sorrow and sighing, but in peace, joy, and cheerfulness, ascending from time to time a step higher. Meanwhile I know (and this knowledge gives me the highest contentment and peace of mind), that all things come to pass by the power and unchangeable decree of a Being supremely perfect.

To return to your letter, I owe you many and sincere thanks for having confided to me your philosophical opinions; but for the doctrines, which you attribute to me, and seek to infer from my letter, I return you no thanks at all. What ground, I should like to know, has my letter afforded you for ascribing to me the opinions: that men are like beasts, that they die and perish after the manner of beasts, that our actions are displeasing to God, etc.? Perhaps we are most of all at variance on this third point. You think, as far as I can judge, that God takes pleasure in our actions, as though he were a man, who has attained his object, when things fall out as he desired. For my part, have I not said plainly enough, that the good worship God, that in continually serving him they become more perfect, and that they love God? Is this, I ask, likening them to beasts, or saying that they perish like beasts, or that their actions are displeasing to God? If you had read my letter with more attention, you would have clearly perceived, that our whole dissension lies in the following alternative: Either the perfections which the good receive are imparted to them by God in his capacity of God, that is absolutely without any human qualities being ascribed to him—this is what I believe; or else such perfections are imparted by God as a judge, which is what you maintain. For this reason you defend the wicked, saying that they carry out God’s decrees as far as in them lies, and therefore serve God no less than the good. But if my doctrine be accepted, this consequence by no means follows; I do not bring in the idea of God as a judge, and, therefore I estimate an action by its intrinsic merits, not by the powers of its performer; the recompense which follows the action follows from it as necessarily as from the nature of a triangle it follows, that the three angles are equal to two right angles. This may be understood by every one who reflects on the fact, that our highest blessedness consists in love toward God, and that such love flows naturally from the knowledge of God, which is so strenuously enjoined on us. The question may very easily be proved in general terms, if we take notice of the nature of God’s decrees, as explained in my appendix. However, I confess that all those, who confuse the divine nature with human nature, are gravely hindered from understanding it.

I had intended to end my letter at this point, lest I should prove troublesome to you in these questions, the discussion of which (as I discover from the extremely pious postscript added to your letter) serves you as a pastime and a jest, but for no serious use. However, that I may not summarily deny your request, I will proceed to explain further the words privation and negation, and briefly point out what is necessary for the elucidation of my former letter.

I say then, first, that PRIVATION is not the act of depriving, but simply and merely a state of want, which is in itself nothing: it is a mere entity of the reason, a mode of thought framed in comparing one thing with another. We say, for example, that a blind man is deprived of sight, because we readily imagine him as seeing, or else because we compare him with others who can see, or compare his present condition with his past condition when he could see; when we regard the man in this way, comparing his nature either with the nature of others or with his own past nature, we affirm that sight belongs to his nature, and therefore assert that he has been deprived of it. But when we are considering the nature and decree of God, we cannot affirm privation of sight in the case of the aforesaid man any more than in the case of a stone; for at the actual time sight lies no more within the scope of the man than of the stone; SINCE THERE BELONGS TO MAN AND FORMS PART OF HIS NATURE ONLY THAT WHICH IS GRANTED TO HIM BY THE UNDERSTANDING AND WILL OF GOD. Hence it follows that God is no more the cause of a blind man not seeing, than he is of a stone not seeing. Not seeing is a pure negation. SO ALSO, WHEN WE CONSIDER THE CASE OF A MAN WHO IS LED BY LUSTFUL DESIRES, WE COMPARE HIS PRESENT DESIRES WITH THOSE WHICH EXIST IN THE GOOD, OR WHICH EXISTED IN HIMSELF AT SOME OTHER TIME; WE THEN ASSERT THAT HE IS DEPRIVED OF THE BETTER DESIRES, BECAUSE WE CONCEIVE THAT VIRTUOUS DESIRES LIE WITHIN THE SCOPE OF HIS NATURE. THIS WE CANNOT DO, IF WE CONSIDER THE NATURE AND DECREE OF GOD. FOR, FROM THIS POINT OF VIEW, VIRTUOUS DESIRES LIE AT THAT TIME NO MORE WITHIN THE SCOPE OF THE NATURE OF THE LUSTFUL MAN, THAN WITHIN THE SCOPE OF THE NATURE OF THE DEVIL OR A STONE. Hence, from the latter standpoint the virtuous desire is not a privation but a negation.

Thus PRIVATION is nothing else than denying of a thing something, which we think belongs to its nature; NEGATION is denying of a thing something, which we do not think belongs to its nature.

We may now see, how Adam’s desire for earthly things was evil from our standpoint, but not from God’s. Although God knew both the present and the past state OF ADAM, HE DID NOT, THEREFORE, REGARD ADAM AS DEPRIVED OF HIS PAST STATE, THAT IS, HE DID NOT REGARD ADAM’S PAST STATE AS WITHIN THE SCOPE OF ADAM’S PRESENT NATURE. Otherwise God would have apprehended something contrary to his own will, that is, contrary to his own understanding. If you quite grasp my meaning here and at the same time remember, that I do not grant to the mind the same freedom as Descartes does—L[ewis] M[eyer] bears witness to this in his preface to my book—you will preceive that there is not the smallest contradiction in what I have said. But I see that I should have done far better to have answered you in my first letter with the words of Descartes, to the effect that we cannot know how our freedom and its consequences agree with the foreknowledge and freedom of God (see several passages in my appendix), that, therefore, we can discover no contradiction between creation by God and our freedom, because we cannot understand how God created the universe, nor (what is the same thing) how he preserves it. I thought that you had read the preface, and that by not giving you my real opinions in reply, I should sin against those duties of friendship which I cordially offered you. But this is of no consequence.

Still, as I see that you have not hitherto thoroughly grasped Descartes’s meaning, I will call your attention to the two following points: First, that neither Descartes nor I have ever said, that it appertains to our nature to confine the will within the limits of the understanding; we have only said, that God has endowed us with a determined understanding and an undetermined will, so that we know not the object for which he has created us. Further, that an undetermined or perfect will of this kind not only makes us more perfect, but also, as I will presently show you, is extremely necessary for us.

Secondly: that our freedom is not placed in a certain contingency nor in a certain indifference, but in the method of affirmation or denial; so that, in proportion as we are less indifferent in affirmation or denial, so are we more free. For instance, if the nature of God be known to us, it follows as necessarily from our nature to affirm that God exists, as from the nature of a triangle it follows, that the three angles are equal to two right angles; we are never more free than when we affirm a thing in this way. As this necessity is nothing else but the decree of God (as I have clearly shown in my appendix), we may hence, after a fashion, understand how we act freely and are the cause of our action, though all the time we are acting necessarily and according to the decree of God. This, I repeat, we may, after a fashion, understand, whenever we affirm something, which we clearly and distinctly perceive, but when we assert something which we do not clearly and distinctly understand, in other words, when we allow our will to pass beyond the limits of our understanding, we no longer perceive the necessity nor the decree of God, we can only see our freedom which is always involved in our will; in which respect only our actions are called good or evil. If we then try to reconcile our freedom with God’s decree and continuous creation, we confuse that which we clearly and distinctly understand with that which we do not perceive, and therefore, our attempt is vain. It is, therefore, sufficient for us to know that we are free, and that we can be so notwithstanding God’s decree, and further that we are the cause of evil, because an act can only be called evil in relation to our freedom. I have said thus much for Descartes in order to show that, in the question we are considering, his words exhibit no contradiction.

I will now turn to what concerns myself, and will first briefly call attention to the advantage arising from my opinion, inasmuch as, according to it, our understanding offers our mind and body to God freed from all superstition. Nor do I deny that prayer is extremely useful to us. For my understanding is too small to determine all the means whereby God leads men to the love of himself, that is, to salvation. So far is my opinion from being hurtful, that it offers to those who are not taken up with prejudices and childish superstitions, the only means for arriving at the highest stage of blessedness.

When you say that, by making men so dependent on God, I reduce them to the likeness of the elements, plants or stones, you sufficiently show that you have thoroughly misunderstood my meaning, and have confused things which regard the understanding with things which regard the imagination. If by your intellect only you had perceived what dependence on God means, you certainly would not think that things, in so far as they depend on God are dead, corporeal, and imperfect (who ever dared to speak so meanly of the Supremely Perfect Being?); on the contrary, you would understand that for the very reason that they depend on God they are perfect; so that this dependence and necessary operation may best be understood as God’s decree, by considering, not stocks and plants, but the most reasonable and perfect creatures. This sufficiently appears from my second observation on the meaning of Descartes, which you ought to have looked to.

I cannot refrain from expressing my extreme astonishment at your remarking, that if God does not punish wrong-doing (that is, as a judge does, with a punishment not intrinsically connected with the offense, for our whole difference lies in this), what reason prevents me from rushing headlong into every kind of wickedness? Assuredly he, who is only kept from vice by the fear of punishment (which I do not think of you), is in no wise acted on by love, and by no means embraces virtue. For my own part, I avoid or endeavor to avoid vice, because it is at direct variance with my proper nature and would lead me astray from the knowledge and love of God.

Again, if you had reflected a little on human nature and the nature of God’s decree (as explained in my appendix), and perceived, and known by this time, how a consequence should be deduced from its premises, before a conclusion is arrived at; you would not so rashly have stated that my opinion makes us like stocks, etc.: nor would you have ascribed to me the many absurdities you conjure up.

As to the two points which you say, before passing on to your second rule, that you cannot understand; I answer, that the first may be solved through Descartes, who says that in observing your own nature you feel that you can suspend your judgment. If you say that you do not feel that you have at present sufficient force to keep your judgment suspended, this would appear to Descartes to be the same as saying that we cannot at present see, that so long as we exist we shall always be thinking things, or retain the nature of thinking things; in fact it would imply a contradiction.

As to your second difficulty, I say with Descartes, that if we cannot extend our will beyond the bounds of our extremely limited understanding, we shall be most wretched—it will not be in our power to eat even a crust of bread, or to walk a step, or to go on living, for all things are uncertain and full of peril.

I now pass on to your second rule, and assert that I believe, though I do not ascribe to Scripture that sort of truth which you think you find in it, I nevertheless assign to it as great if not greater authority than you do. I am far more careful than others not to ascribe to Scripture any childish and absurd doctrines, a precaution which demands either a thorough acquaintance with philosophy or the possession of divine revelations. Hence I pay very little attention to the glosses put upon Scripture by ordinary theologians, especially those of the kind who always interpret Scripture according to the literal and outward meaning: I have never, except among the Socinians, found any theologian stupid enough to ignore that Holy Scripture very often speaks in human fashion of God and expresses its meaning in parables; as for the contradiction which you vainly (in my opinion) endeavor to show, I think you attach to the word parable a meaning different from that usually given. For who ever heard, that a man, who expressed his opinions in parables, had therefore taken leave of his senses? When Micaiah said to King Ahab, that he had seen God sitting on a throne, with the armies of heaven standing on the right hand and the left, and that God asked his angels which of them would deceive Ahab, this was assuredly a parable employed by the prophet on that occasion (which was not fitted for the inculcation of sublime theological doctrines), as sufficiently setting forth the message he had to deliver in the name of God. We cannot say that he had in anywise taken leave of his senses. So also the other prophets of God made manifest God’s commands to the people in this fashion as being the best adapted, though not expressly enjoined by God, for leading the people to the primary object of Scripture, which, as Christ himself says, is to bid men love God above all things, and their neighbor as themselves. Sublime speculations have, in my opinion, no bearing on Scripture. As far as I am concerned I have never learned or been able to learn any of God’s eternal attributes from Holy Scripture.

As to your fifth argument (that the prophets thus made manifest the word of God, since truth is not at variance with truth), it merely amounts, for those who understand the method of proof, to asking me to prove, that Scripture, as it is, is the true revealed word of God. The mathematical proof of this proposition could only be attained by divine revelation. I, therefore, expressed myself as follows: “I BELIEVE, BUT I DO NOT MATHEMATICALLY KNOW, THAT ALL THINGS REVEALED BY GOD TO THE PROPHETS,” etc. Inasmuch as I firmly believe but do not mathematically know, that the prophets were the most trusted counsellors and faithful ambassadors of God. So that in all I have written there is no contradiction, though several such may be found among holders of the opposite opinion.

The rest of your letter (to wit the passage where you say, “Lastly, the supremely perfect Being knew before-hand,” etc; and again, your objections to the illustration from poison, and lastly, the whole of what you say of the appendix and what follows) seems to me beside the question.

As regards Lewis Meyer’s preface, the points which were still left to be proved by Descartes before establishing his demonstration of free will, are certainly there set forth; it is added that I hold a contrary opinion, my reasons for doing so being given. I shall, perhaps, in due time, give further explanations. For the present I have no such intention.

I have never thought about the work on Descartes, nor given any further heed to it, since it has been translated into Dutch. I have my reasons, though it would be tedious to enumerate them here. So nothing remains for me but to subscribe myself, etc.

Spinoza to Blyenbergh.

[Spinoza replies, that there is a difference between the theological and the philosophical way of speaking of God and things divine. He proceeds to discuss Blyenbergh’s questions.]

Voorburg, 13th March, 1665.

Friend and Sir,—I have received two letters from you this week; the second, dated 9th March, only served to inform me of the first written on February 19th, and sent to me at Schiedam. In the former I see that you complain of my saying, that “demonstration carried no weight with you,” as though I had spoken of my own arguments, which had failed to convince you. Such was far from my intention. I was referring to your own words, which ran as follows:—“And if after long investigation it comes to pass, that my natural knowledge appears either to be at variance with the word (of Scripture), or not sufficiently well, etc.; the word has so great authority with me, that I would rather doubt of the conceptions, which I think I clearly perceive,” etc. You see I merely repeat in brief your own phrase, so that I cannot think you have any cause for anger against me, especially as I merely quoted in order to show the great difference between our standpoints.

Again, as you wrote at the end of your letter that your only hope and wish is to continue in faith and hope, and that all else, which we may become convinced of through our natural faculties, is indifferent to you; I reflected, as I still continue to do, that my letters could be of no use to you, and that I should best consult my own interests by ceasing to neglect my pursuits (which I am compelled while writing to you to interrupt) for the sake of things which could bring no possible benefit. Nor is this contrary to the spirit of my former letter, for in that I looked upon you as simply a philosopher, who (like not a few who call themselves Christians) possesses no touchstone of truth save his natural understanding, and not as a theologian. However, you have taught me to know better, and have also shown me that the foundation, on which I was minded to build up our friendship, has not, as I imagined, been laid.

As for the rest, such are the general accompan
