“Letter to the Community of Marseille” (“Letter on Astrology”)

 

Maimonides


 

 

I perceive in this inquiry that although its boughs are many, they are all branches of a single tree, which is their common root: namely, all the statements of “the astrologers, the stargazers” (Is. 47:13). It is evident that the compilation we have made of the statutes of the Torah, which we entitled Mishneh Torah, has not reached you. If it had, you would have known directly my opinion regarding all those things of which you have inquired; for we have made this entire matter clear in (the section of that work called) Laws Concerning Idolatry and the Ordinances of the Nations. It seems to me that it will come to you before this reply, since it is already widespread on the island of Sicily, as well as in the West and in the East and in the South. In any case, I myself need to make this clear to you.

Know, my masters, that it is not proper for a man to accept as trustworthy anything other than one of these three things. The first is a thing for which there is a clear proof deriving from man’s reasoning—such as arithmetic’ geometry, and astronomy. The second is a thing that a man perceives through one of the five senses—such as when he knows with certainty that this is red and this is black and the like through the sight of his eye; or as when he tastes that this is bitter and this is sweet; or as when he feels that this is hot and this is cold; or as when he hears that this sound is clear and this sound is indistinct; or as when he smells that this is a pleasing smell and this is a displeasing smell and the like. The third is a thing that a man receives from the prophets or from the righteous. Every reasonable man ought to distinguish in his mind and thought all the things that he accepts as trustworthy, and say: “This I accept as trustworthy because of tradition, and this because of sense-perception, and this on grounds of reason.” Anyone who accepts as trustworthy anything that is not of these three species, of him it is said: “The simple believes everything” (Prov. 14:15).

Thus you ought to know that fools have composed thousands of books of nothingness and emptiness. Any number of men, great in years but not in wisdom, wasted all their days in studying these books and imagined that these follies are science. They came to think of themselves as wise men because they knew that science. The thing about which most of the world errs, or all of it—save for a few individuals, “the remnant of whom the Lord shall call” (Joel 3:5)—is that thing of which I am apprising you. The great sickness and the “grievous evil” (Eccles. 5:12, 15) consist in this: that all the things that man finds written in books, he presumes to think of as true—and all the more so if the books are old. And since many individuals have busied themselves with those books and have engaged in discussions concerning them, the rash fellow’s mind at once leaps to the conclusion that these are words of wisdom, and he says to himself: “Has the pen of the scribes written in vain” (Jer. 8:8), and have they vainly engaged in these things? This is why our kingdom was lost and our Temple was destroyed and why we were brought to this; for our fathers sinned and are no more because they found many books dealing with these themes of the star gazers, these things being the root of idolatry, as we have made clear in Laws Concerning Idolatry. They erred and were drawn after them, imagining them to be glorious science and to be of great utility. They did not busy themselves with the art of war or with the conquest of lands, but imagined that those studies would help them. Therefore the prophets called them “fools and dolts” (Jer. 4:22). And truly fools they were, “for they walked after confused things that do not profit” (I Sam. 12:21 and Jer. 2:8).

Know, my masters, that I myself have investigated much into these matters. The first thing I studied is that science which is called judicial astrology—that is, (the science) by which man may know what will come to pass in the world or in this or that city or kingdom and what will happen to a particular individual all the days of his life. I also have read in all matters concerning all of idolatry, so that it seems to me there does not remain in the world a composition on this subject, having been translated into Arabic from other languages, but that I have read it and have understood its subject matter and have plumbed the depth of its thought. From those books it became clear to me what the reason is for all those commandments that everyone comes to think of as having no reason at all other than the decree of Scripture. I already have a great composition on this subject in the Arabic language (namely, the Guide of the Perplexed) with lucid proofs for every single commandment but this is not required of us now. I now return to the subject of your inquiry.

Know, my masters, that every one of those things concerning judicial astrology that (its adherents) maintain—namely, that something will happen one way and not another, and that the constellation under which one is born will draw him on so that he will be of such and such a kind and so that something will happen to him one way and not another—all those assertions are far from being scientific; they are stupidity. There are lucid, faultless proofs refuting all the roots of those assertions. Never did one of those genuinely wise men of the nations busy himself with this matter or write on it, no (nation) wrote such compositions or committed the error of calling it a science, other than the Chasdeans, Chaldeans, Canaanites, and Egyptians, for that was their religion in those days. But the wise men of Greece—and they are the philosophers who wrote on science and busied themselves with all the species of science—mock and scorn and ridicule these four nations that I have mentioned to you, and they rally proofs to refute their entire position “root and branch” (Mal. 3:19). The wise men of Persia also recognized and understood that all that science which the Chasdeans, Chaldeans, Egyptians, and Canaanites produced is a falsehood and a lie. Do not imagine that those refutations are mere assertions and that we therefore should not put our trust in them; rather there are lucid and correct, faultless proofs to refute that entire position, and the only one who would cling to it would be “a simple one who believes everything”(Prov. 14:15), or one who wishes to deceive others.

And know, my masters, that the science of the stars that is genuine science is knowledge of the form of the spheres, their number, their measure, the course they follow, each one’s period of revolution, their declination to the north or to the south, their revolving to the east or to the west, and the orbit of every star and what its course is. On all this and the like, the wise men of Greece, Persia, and India wrote compositions. This is an exceedingly glorious science. By means of it the onset of the eclipses of luminaries may be known and when they will be eclipsed at any given place; by means of it there may be known the cause for the moon’s (yareah) appearing just like a bow, then waxing great until it is full, and then gradually waning; by means of it there may be known when the moon (levanah) will or will not be seen; and the reason why one day will be long and another day short; and the reason why two stars will rise as one, but not set together; and the reason why a given day at a given place is thirteen hours long and in another place fifteen or sixteen or twenty hours long, yet being a single day. (In one place the day and the night will be of equal duration; in another place the day will be like a month or two months or three—so that a place may be found where the entire year is a single day, six months daytime and six months nighttime.) How many amazing conditions are made intelligible by this science, all of which is undoubtedly true. It is this calculation of astronomical cycles of which the (Talmudic) sages said that it is wisdom and understanding in the sight of the (Gentile) peoples (Shabbat 75a). But as for these assertions of the stupid astrologers, they are nothing. I am now making clear to you the main points of those matters that are the mystery of the world.

Know, that all the wise men of the Gentile nations—and they are the great philosophers, men of intellect and science—were all in accord that the world has a Governor; He makes a sphere revolve, the sphere not revolving of itself. They have many books advancing a lucid proof for this; on this point there is no controversy among men of science. There is, however, a great controversy among them regarding this entire world, namely, the sphere and what is beneath it.

(1) Most of them say that it is not subject to generation and corruption, but that as it is now, it was and it will be forever and ever. Just as the Holy One, blessed be He, who was always the same as He is now, is making it revolve, so was He always making it revolve, and it was always being revolved; the two of them were always together, never was one without the other.

(2) Among them there are those who maintain that this sphere has come into being and that the Deity has created it, but that there is a single thing that exists together with the Creator, “like the clay in the potter’s hand” (Jer. 18:6). From that thing which exists together with Him, He makes whatever He pleases. Sometimes He will use some of that clay, as it were, to make heaven and some of it to make earth; and sometimes, if He pleases, He takes some of that out of which He has made heaven and makes something else out of it. But to bring forth something out of nothing is impossible.

(3) Among the philosophers there are those who maintain—just as the prophets maintained—that the Holy One, blessed be He, created all created things out of nothing and that there is no other thing with the Creator aside from the creation that He has brought forth.

Now the great controversy is over this point, and this is the very point that Abraham our Father discerned. A thousand books have already been written on this, with proofs that each and every one of them rallies to support its position. It is the root of the Torah that the Deity alone is primordial and that He has created the whole out of nothing; whoever does not acknowledge this is guilty of radical unbelief and is guilty of heresy. I myself have already written a great composition in Arabic (Guide of the Perplexed) on these matters. I have explained the lucid proofs of the existence of the Creator and that He is one and that He is not a body or corporeal in any respect. I have shattered all those proofs that the philosophers advance as proving that the world was not created. In addition, I have resolved all the great difficulties that they have raised against us on account of our maintaining that the Deity has created everything that exists out of nothing.... All these, then, are the three sects into which the wise men of the world fall, from the earliest antiquity down to now.

(l ) Those who maintain that the sphere is not a created thing, but that it eternally has been and will be just as it is.

( 2 ) Those who maintain that the Deity has created it out of that matter which always exists by Him.

( 3 ) Those who maintain—just as all the prophets did—that there is no other thing that is with the Deity, just He Himself, and that when He wished, He brought forth this world out of nothing, in conformity with His will.

All of these three sects are in accord on the following point. Everything that comes into being in this lower world—namely, every “living soul” (Gen. 1:30) and every tree and every species of grass and every one of the species of minerals—the whole has the Deity as its maker, through a power coming from the spheres and the stars. And they are in accord that the power of the Creator flows first upon the spheres and the stars; from the spheres and the stars it flows and spreads through this (lower) world—everything that is, thereby coming into being. Just as we maintain that the Holy One, blessed be He, performs signs and wonders through the angels, so do these philosophers maintain that all these occurrences in the nature of the world come through the spheres and the stars. They maintain that the spheres and the stars possess souls and knowledge. All these things are true. I myself have already made it clear, with proofs, that all these things involve no damage to religion. And not only this, but what is more I have understood from the sayings of the sages in all of the Midrashim that they maintain as the philosophers maintained. There is no controversy whatever between the sages of Israel and the philosophers on these matters, as I have made clear in those chapters [in the Guide of the Perplexed, a philosophical treatise].

All three of these sects of the philosophers, which maintain that everything is made by means of the spheres and the stars, also maintain that whatever happens to each and every human being is due to chance; it is not due to any cause coming from above, and neither the constellation under which one is born nor nature will avail against it. There is no difference for them between this individual who was torn to pieces by a lion that happened upon him, or this mouse that was torn to pieces by a cat, or this fly that was torn to pieces by a spider. Neither is there a difference between a roof’s falling upon and killing someone, or a rock’s breaking loose from a mountain and falling upon a tree or upon another rock and breaking it. All this, they maintain, is simply fortuitous. It is said as well of those human beings who are warring with one another over a great kingdom, that they are like a pack of dogs warring over a carcass. This is not due to any cause coming from the stars. Furthermore, this one being poor and that one rich, this one having children and that one being childless—all the philosophers maintain that this is due to chance. The summary of the matter is that they maintain that what happens to each and every thing—be it man or beast or trees and minerals—is all due to chance. But the being of all the species and the things comprehended in the entire world—in which there is not the activity of a living soul—all of this stems from the power of the spheres whose root, in turn, comes from the Holy One, blessed be He. The controversy lies in this, that the true religionists, and that is the religion of Moses our Teacher, maintain that what happens to individuals is not due to chance, but rather to judgment—as the Torah says: “For all His ways are judgment” (Deut. 32:4). The prophet explained: “Whose eyes are open upon all the ways of the sons of men, to give every one according to his ways, and according to the fruit of his doings” (Jer. 32:19). It is regarding this that the Torah warned and bore witness and told Israel: “But if you will not hearken to Me” (Lev. 26:14), I shall bring hardship upon you. If you maintain that that hardship is not an affliction brought on by your sins, but rather due to chance and one of those things that happen by chance, why then I Myself shall heap more of that chance upon you—as it is written: “And if you walk with Me in (the way of) chance, I too shall walk with you in the wrath of chance” (Lev. 26:27-28). This is a root of the religion of Moses our Teacher, that everything happening to human beings is a (just) decree and judgment. Hence, the sages maintained: “There is no death without sin and no affliction without transgression” (Shabbat 55a).

And know, my masters, that it is one of the roots of the religion of Moses our Teacher—and one that all the philosophers also acknowledge—that every action of human beings is left to them and that there is nothing to constrain or draw them. Rather, if he so pleases, a man will worship God and become wise and sit in the house of study. And if he so pleases, he will follow the counsel of the wicked and run with thieves and hide with adulterers. There is no influence or constellation under which one is born that will draw him in any manner toward any one of these ways. Hence it was commanded and told to him: “Do this and do not do that.” We have made clear many of the things involved in these matters in most of our Arabic compositions, in the Commentary on the Mishna and in the rest of the compositions. Thus we ought to know that what happens to human beings is not—as the philosophers maintain—like what happens to the beast.

Three disagreements are to be found in these matters. Imagine this situation. Here is Reuben, a tanner, poor, and his children have died in his own lifetime. And here is Simon, a perfumer, rich, and his children stand before him.

(1 ) The philosopher will maintain that this is due to chance. It is possible that Reuben could become a perfumer, grow rich, and have children; and it is possible that Simon could become impoverished, turn into a tanner, and witness his children’s death. All this is simply fortuitous. There is no nature in the world and no power emanating from a star that caused this individual to be or not to be thus. This is the position of the philosophers.

(2) The second position is that of those who believe in judicial astrology and whose sayings you have heard and whose follies are widespread among you. They maintain that it is impossible that a given thing should ever change. Never will Reuben be anything other than a tanner and poor and childless, for it was thus fixed by the power of the sphere at the time of his birth. Similarly, it is impossible for Simon to be anything other than a perfumer and rich and with surviving children, just as it was fixed by the power of the sphere at the time of his birth.

These two ways, or these two positions, are regarded as falsehoods by us. The position of the astrologers is given the lie by reason, for correct reasoning has already refuted, by means of lucid proofs, all those follies that they have maintained. It also is regarded as a falsehood by us because of the religious tradition, for if the matter stood thus, of what utility would the Torah and the commandment and the Talmud be to a particular individual? For in that event, every single individual would lack the power to do anything he set his mind to, since something else draws him on—against his will—to be this and not to be that; of what use then is the command or the Talmud? The roots of the religion of Moses our Teacher, we find, refute the position of these stupid ones—in addition to reason’s doing so with all those proofs that the philosophers maintain to refute the position of the Chasdeans and the Chaldeans and their associates. The position of the philosophers who maintain that these things are due to chance is also regarded as a falsehood by us because of the religious tradition.

(3) The true way upon which we rely and in which we walk is this: We say regarding this Reuben and Simon, that there is nothing that draws on the one to become a perfumer and rich, and the other to become a tanner and poor. It is possible that the situation will change and be reversed, as the philosopher maintains. But the philosopher maintains that this is due to chance. We maintain that it is not due to chance, but rather that this situation depends on the will of “Him who spoke, and (the world) came into being” (Ps. 33:9); all of this is a (just) decree and judgment. We do not know the end of the Holy One’s wisdom so as to know by what decree and judgment He required that this should be this way and that that should be the other way; “for His ways are not like our ways, neither are His thoughts like our thoughts” (Is. 55:8). We rather are obliged to fix in our minds that if Simon sins, he will be punished with stripes and impoverished and his children will die and the like. And if Reuben repents and mends his ways and searches his deeds and walks in a straight path, he will grow rich and will succeed in all his undertakings and “see (his) seed and prolong (his) days” (ibid. 55:10). This is a root of the religion. If a man says, “But look, many have acted in this way and yet have not succeeded,” why, this is no proof. [For] either some iniquity of theirs caused this, or they are now afflicted in order to inherit something even better than this. [But not afflicted in the senses that they are sinners, and a subsequent good will be a “reward”. Maimonides means they are dealt a trail through which they will emerge with a greater good. An example is when God commanded Abraham to sacrifice Isaac. This was not commanded as a means of suffering so that Abraham might thereby be ‘owed” a subsequent good. Rather, it was to actualize Abraham’s potential, for his own good.]

The summary of the matter is that our mind cannot grasp how the decrees of the Holy One, blessed be He, work upon human beings in this world and in the world to come. What we have said about this from the beginning is that the entire position of the stargazers is regarded as a falsehood by all men of science. I know that you may search and find sayings of some individual sages in the Talmud and Midrashim whose words appear to maintain that at the moment of a man’s birth, the stars will cause such and such to happen to him. Do not regard this as a difficulty, for it is not fitting for a man to abandon the prevailing law and raise once again the counterarguments and replies (that preceded its enactment). Similarly it is not proper to abandon matters of reason that have already been verified by proofs, shake loose of them, and depend on the words of a single one of the sages from whom possibly the matter was hidden. Or there may be an allusion in those words; or they may have been said with a view to the times and the business before him. (You surely know how many of the verses of the holy Law are not to be taken literally. Since it is known through proofs of reason that it is impossible for the thing to be literally so, the translator [of the Aramaic Targum] rendered it in a form that reason will abide. ) A man should never cast his reason behind him, for the eyes are set in front, not in back.

Do not censure me, my masters, for the brevity of these remarks, for the writing makes it clear that I wrote it to fill a present need. For I was very busy with many Gentile affairs. The Deity knows that if Rabbi Pinhas had not sent a messenger who “urged me till I was ashamed” (II Kings 2:17) and did not leave my presence until I had written it, I would not be replying now since I have no leisure. On this account, judge in my favor. Farewell, my brothers, friends, and masters; may you increase and be exalted forever. Amen.
