The Guide for the Perplexed

From Time-Atoms

The Guide for the Perplexed by Moses Maimonides

Part I, Chapter LXXIII

THERE are twelve propositions common to all Mutakallemim, however different their individual opinions and methods may be; the Mutakallemim require them in order to establish their views on the four principles. I shall first enumerate these propositions, and then discuss each separately, together with the inferences which may be drawn from it.

PROPOSITION I. All things are composed of atoms.

PROPOSITION II. There is a vacuum.

PROPOSITION III. Time is composed of time-atoms.

PROPOSITION IV. Substance cannot exist without numerous accidents.

PROPOSITION V. Each atom is completely furnished with the accidents (which I will describe), and cannot exist without them.

PROPOSITION VI. Accidents do not continue in existence during two time-atoms.

PROPOSITION VII. Both positive and negative properties have a real existence, and are accidents which owe their existence to some causa efficiens.

PROPOSITION VIII. All existing things, i.e., all creatures, consist of substance and of accidents, and the physical form of a thing is likewise an accident.

PROPOSITION IX. No accident can form the substratum for another accident.

PROPOSITION X. The test for the possibility of an imagined object does not consist in its conformity with the existing laws of nature.

PROPOSITION XI. The idea of the infinite is equally inadmissible, whether the infinite be actual, potential, or accidental, i.e., there is no difference whether the infinite be formed by a number of co-existing things, or by a series of things, of which one part comes into existence when another has ceased to exist, in which case it is called accidental infinite: in both cases the infinite is rejected by the Mutakallemim as fallacious.

PROPOSITION XII. The senses mislead, and are in many cases inefficient; their perceptions, therefore, cannot form the basis of any law, or yield data for any proof.

FIRST PROPOSITION.

“The Universe, that is, everything contained in it, is composed of very small parts [atoms] which are indivisible on account of their smallness; such an atom has no magnitude; but when several atoms combine, the sum has a magnitude, and thus forms a body. If, therefore, two atoms were joined together, each atom would become a body, and they would thus form two bodies, a theory which in fact has been proposed by some Mutakallemim. All these atoms are perfectly alike; they do not differ from each other in any point. The Mutakallemim further assert, that it is impossible to find a body that is not composed of such equal atoms which are placed side by side. According to this view genesis and composition are identical; destruction is the same as decomposition. They do not use the term “destruction,” for they hold that “genesis” implies composition and decomposition, motion and rest. These atoms, they believe, are not, as was supposed by Epicurus and other Atomists numerically constant: but are created anew whenever it pleases the Creator: their annihilation is therefore not impossible. Now I will explain to you their opinion concerning the vacuum.

SECOND PROPOSITION.

On the vacuum. The original Mutakallemim also believe that there is a vacuum. i.e., one space, or several spaces which contain nothing, which are not occupied by anything whatsoever, and which are devoid of all substance. This proposition is to them an indispensable sequel to the first. For, if the Universe were full of such atoms, how could any of them move? For it is impossible to conceive that one atom should move into another. And yet the composition, as well as the decomposition of things, can only be effected by the motion of atoms! Thus the Mutakallemim are compelled to assume a vacuum, in order that the atoms may combine, separate, and move in that vacuum which does not contain any thing or any atom.

THIRD PROPOSITION.

“Time is composed of time-atoms,” i.e., of many parts, which on account of their short duration cannot be divided. This proposition also is a logical consequence of the first. The Mutakallemim undoubtedly saw how Aristotle proved that time, space, and locomotion are of the same nature, that is to say, they can be divided into parts which stand in the same proportion to each other: if one of them is divided, the other is divided in the same proportion. They, therefore, knew that if time were continuous and divisible ad infinitum, their assumed atom of space would of necessity likewise be divisible. Similarly, if it were supposed that space is continuous, it would necessarily follow, that the time-element, which they considered to be indivisible, could also be divided. This has been shown by Aristotle in the treatise called Acroasis. Hence they concluded that space was not continuous, but was composed of elements that could not be divided; and that time could likewise be reduced to time-elements, which were indivisible. An hour is, e.g., divided into sixty minutes, the minute into sixty seconds, the second into sixty parts, and so on: at last after ten or more successive divisions by sixty, time-elements are obtained, which are not subjected to division, and in fact are indivisible, just as is the case with space. Time would thus be an object of position and order.

The Mutakallemim did not at all understand the nature of time. This is a matter of course: for if the greatest philosophers became embarrassed when they investigated the nature of time, if some of them were altogether unable to comprehend what time really was, and if even Galenus declared time to be something divine and incomprehensible, what can be expected of those who do not regard the nature of things?

Now, mark what conclusions were drawn from these three propositions and were accepted by the Mutakallemim as true. They held that locomotion consisted in the translation of each atom of a body from one point to the next one; accordingly the velocity of one body in motion cannot be greater than that of another body. When, nevertheless, two bodies are observed to move during the same time through different spaces, the cause of this difference is not attributed by them to the fact that the body which has moved through a larger distance had a greater velocity, but to the circumstance that motion which in ordinary language is called slow, has been interrupted by more moments of rest, while the motion which ordinarily is called quick has been interrupted by fewer moments of rest. When it is shown that the motion of an arrow, which is shot from a powerful bow, is in contradiction to their theory, they declare that in this case too the motion is interrupted by moments of rest. They believe that it is the fault of man’s senses if he believes that the arrow moves continuously, for there are many things which cannot be perceived by the senses, as they assert in the twelfth proposition. But we ask them: “Have you observed a complete revolution of a millstone? Each point in the extreme circumference of the stone describes a large circle in the very same time in which a point nearer the centre describes a small circle: the velocity of the outer circle is therefore greater than that of the inner circle. You cannot say that the motion of the latter was interrupted by more moments of rest; for the whole moving body, i.e., the millstone, is one coherent body.” They reply, “During the circular motion, the parts of the millstone separate from each other, and the moments of rest interrupting the motion of the portions nearer the centre are more than those which interrupt the motion of the outer portions.” We ask again, “How is it that the millstone, which we perceive as one body, and which cannot be easily broken, even with a hammer, resolves into its atoms when it moves, and becomes again one coherent body, returning to its previous state as soon as it comes to rest, while no one is able to notice the breaking up [of the stone]?” Again their reply is based on the twelfth proposition, which is to the effect that the perception of the senses cannot be trusted, and thus only the evidence of the intellect is admissible. Do not imagine that you have seen in the foregoing example the most absurd of the inferences which may be drawn from these three propositions: the proposition relating to the existence of a vacuum leads to more preposterous and extravagant conclusions. Nor must you suppose that the aforegoing theory concerning motion is less irrational than the proposition resulting from this theory, that the diagonal of a square is equal to one of its sides, and some of the Mutakallemim go so far as to declare that the square is not a thing of real existence. In short, the adoption of the first proposition would be tantamount to the rejection of all that has been proved in Geometry. The propositions in Geometry would, in this respect, be divided into two classes: some would be absolutely rejected: e.g., those which relate to properties of the incommensurability and the commensurability of lines and planes, to rational and irrational lines, and all other propositions contained in the tenth book of Euclid, and in similar works. Other propositions would appear to be only partially correct: e.g., the solution of the problem to divide a line into two equal parts, if the line consists of an odd number of atoms: according to the theory of the Mutakallemim such a line cannot be bisected. Furthermore, in the well-known book of problems by the sons of Shakir are contained more than a hundred problems, all solved and practically demonstrated: but if there really were a vacuum, not one of these problems could be solved, and many of the waterworks [described in that book] could not have been constructed. The refutation of such propositions is a mere waste of time. I will now proceed to treat of the other propositions mentioned above.

FOURTH PROPOSITION.

“The accidents of things have real existence; they are elements superadded to the substance itself, and no material thing can be without them.” Had this proposition been left by the Mutakallemim in this form it would have been correct, simple, clear, and indisputable. They have, however, gone further, asserting that a substance which has not the attribute of life, must necessarily have that of death; for it must always have one of two contrasting properties. According to their opinion, colour, taste, motion or rest, combination or separation, etc., can be predicated of all substances, and, if a substance have the attribute of life, it must at the same time possess such other kinds of accidents, as wisdom or folly, freewill or the reverse, power or weakness, perception or any of its opposites, and, in short, the substance must have the one or the other of all correlative accidents appertaining to a living being.

FIFTH PROPOSITION.

“The atom is fully provided with all these foregoing accidents, and cannot exist if any be wanting.” The meaning of the proposition is this: The Mutakallemim say that each of the atoms created by God must have accidents, such as colour, smell, motion, or rest, except the accident of quantity: for according to their opinion an atom has no magnitude; and they do not designate quantity as an accident, nor do they apply to it the laws of accidents. In accordance with this proposition, they do not say, when an accident is noticed in a body, that it is peculiar to the body as such, but that it exists in each of the atoms which form the constituent elements of that body. E.g., take a heap of snow; the whiteness does not exist in that heap as a whole, but each atom of the snow is white, and therefore the aggregate of these atoms is likewise white. Similarly they say that when a body moves each atom of it moves, and thus the whole body is in motion. Life likewise exists, according to their view, in each atom of a living body. The same is the case according to their opinion with the senses: in each atom of the aggregate they notice the faculty of perception. Life, sensation, intellect and wisdom are considered by them as accidents, like blackness and whiteness, as will be shown in the further discussion of their theory.

Concerning the soul, they do not agree. The view most predominant among them is the following:–The soul is an accident existing in one of the atoms of which, e.g., man is composed; the aggregate is called a being endowed with a soul, in so far as it includes that atom. Others are of opinion that the soul is composed of ethereal atoms, which have a peculiar faculty by virtue of which they constitute the soul, and that these atoms are mixed with the atoms of the body. Consequently they maintain that the soul is an accident.

As to the intellect, I found that all of them agreed in considering it to be an accident joined to one of the atoms which constitute the whole of the intelligent being. But there is a confusion among them about knowledge: they are uncertain whether it is an accident to each of the atoms which form the knowing aggregate, or whether it belongs only to one atom. Both views can be disproved by a reductio ad absurdum, when the following facts are pointed out to them. Generally metals and stones have a peculiar colour, which is strongly pronounced, but disappears when they are pulverised. Vitriol, which is intensely green, becomes white dust when pounded; this shows that that accident exists only in the aggregate, not in the atoms. This fact is more striking in the following instance: when parts of a living being are cut off they cease to live, a proof that the accident [of life] belongs to the aggregate of the living being, not to each atom. In order to meet this objection they say that the accident is of no duration, but is constantly renewed. In discussing the next proposition I shall explain their view on this subject.

SIXTH PROPOSITION.

“The accidents do not exist during two time-atoms.”–The sense of the proposition is this: They believe that God creates a substance, and simultaneously its accidents: that the Creator is incapable of creating a substance devoid of an accident, for that is impossible: that the essential characteristic of an accident is its incapability of enduring for two periods, for two time-atoms; that immediately after its creation it is utterly destroyed, and another accident of the same kind is created: this again is destroyed and a third accident of the same kind is created, and so on, so long as God is pleased to preserve [in that substance] this kind of accident; but He can at His will create in the same substance an accident of a different kind, and if He were to discontinue the creation and not produce a new accident, that substance would at once cease to exist. This is one of the opinions held by the Mutakallemim; it has been accepted by most of them, and it is the so-called “theory of the creation of the accidents.” Some of them, however, and they belong to the sect of the Mu’tazilah, say that there are accidents which endure for a certain period, and other accidents which do not endure for two atoms of time; they do not follow a fixed principle in deciding what class of accidents has and what class has not a certain duration. The object of this proposition is to oppose the theory that there exists a natural force from which each body derives its peculiar properties. They prefer to assume that God himself creates these properties without the intervention of a natural force or of any other agency: a theory which implies that no accident can have any duration. For suppose that certain accidents could endure for a certain period and then cease to exist, the question would naturally be asked, What is the cause of that non-existence? They would not be satisfied with the reply that God by His will brought about this non-existence, and non-existence does not at all require any agens whatever: for as soon as the agens leaves off acting, the product of the agens ceases likewise to exist. This is true to some extent. Having thus chosen to establish the theory that there does not exist any natural force upon which the existence or non-existence of a thing depends, they were compelled to assume that the properties of things were successively renewed. When God desires to deprive a thing of its existence, He, according to some of the Mutakallemim, discontinues the creation of its accidents, and eo ipso the body ceases to exist. Others, however, say that if it pleased the Almighty to destroy the world, He would create the accident of destruction, which would be without any substratum. The destruction of the Universe would be the correlative accident to that of existence.–In accordance with this [sixth] proposition they say, that the cloth which according to our belief we dyed red, has not been dyed by us at all, but God created that colour in the cloth when it came into contact with the red pigment; we believe that colour to have penetrated into the cloth, but they assert that this is not the case. They say that God generally acts in such a way, that, e.g., the black colour is not created unless the cloth is brought into contact with indigo; but this blackness, which God creates in the instant when the cloth touches the black pigment is of no duration, and another creation of blackness then takes place; they further say that after the blackness is gone, He does not create a red or green colour, but again a black colour.

According to this principle, the knowledge which we have of certain things to-day, is not the same which we had of them yesterday; that knowledge is gone, and another like it has been created. They positively believe that this does take place, knowledge being an accident. In like manner it would follow that the soul, according to those who believe that it is an accident, is renewed each moment in every animated being, say a hundred thousand times; for, as you know, time is composed of time-atoms. In accordance with this principle they assert that when man is perceived to move a pen, it is not he who has really moved it; the motion produced in the pen is an accident which God has created in the pen; the apparent motion of the hand which moves the pen is likewise an accident which God has created in the moving hand; but the creative act of God is performed in such a manner that the motion of the hand and the motion of the pen follow each other closely; but the hand does not act, and is not the cause of the pen’s motion: for, as they say, an accident cannot pass from one thing to another. Some of the Mutakallemim accordingly contend that this white cloth, which is coloured when put into the vessel filled with indigo, has not been blackened by the indigo: for blackness being an attribute of indigo, does not pass from one object to another. There does not exist any thing to which an action could be ascribed: the real agens is God, and He has [in the foregoing instance] created the blackness in the substance of the cloth when it came into contact with the indigo, for this is the method adopted by Him. In short, most of the Mutakallemim believe that it must never be said that one thing is the cause of another; some of them who assumed causality were blamed for doing so. As regards, however, the acts of man their opinions are divided. Most of them, especially the sect of the Asha’ariyah, assume that when the pen is set in motion God has created four accidents, none of which is the cause of any of the rest, they are only related to each other as regards the time of their co-existence, and have no other relation to each other. The first accident is man’s will to move the pen, the second is man’s power to do so, the third is the bodily motion itself, i.e., the motion of the hand, and the fourth is the motion of the pen. They believe that when a man has the will to do a thing and, as he believes, does it, the will has been created for him, then the power to conform to the will, and lastly the act itself. The act is not accomplished by the power created in man: for, in reality, no act can be ascribed to that power. The Mu’tazilah contend that man acts by virtue of the power which has been created in him. Some of the Asha’ariyah assert that the power created in man participates in the act, and is connected with it, an opinion which has been rejected by the majority of them. The will and the power created in man, according to the concurrent belief of the Mutakallemim, together with the act created in him, according to some of them, are accidents without duration. In the instance of the pen, God continually creates one motion after the other so long as the pen is in motion; it only then ceases to move when God has created in it the accident of rest; and so long as the pen is at rest, God continually renews in it that accident. Consequently in every one of these moments, i.e., of the time-atoms, God creates some accident in every existing individual, e.g., in the angels, in the spheres and in other things: this creation takes place continually and without interruption. Such is, according to their opinion, the right interpretation of the creed that God is the causa efficiens. But I, together with all rational persons, apply to those theories the words, “Will you mock at Him, as you mock at man?” for their words are indeed nothing but mockery.
