CHAPTER 17
In the case of everything produced in time, which is generated after not having existed — even in those cases in which the matter of the thing was already existent and in the course of the production of the thing had merely put off one and put on another form — the nature of that particular thing after it has been produced in time, has attained its final state, and achieved stability, is different from its nature when it is being generated and is beginning to pass from potentiality to actuality. It is also different from the nature the thing had before it had moved so as to pass from potentiality to actuality. For example, the nature of the feminine seed, which is the blood in the blood vessels, is different from the nature of this seed as it exists in the state of pregnancy after it has encountered the masculine sperm and has begun to move toward the transition from potentiality to actuality. And even at the latter period, its nature is different from the nature of an animal that, after having been born, achieves perfection. No inference can be drawn in any respect from the nature of a thing after it has been generated, has attained its final state, and has achieved stability [35a] in its most perfect state, to the state of that thing while it moved toward being generated. Nor can an inference be drawn from the state of the thing when it moves toward being generated to its state before it begins to move thus. Whenever you err in this and draw an inference from the nature of a thing that has achieved actuality to its nature when it was only in potentia, grave doubts are aroused in you. Moreover, things that must exist become impossible in your opinion, and on the other hand things that are impossible become necessary in your opinion. Assume, according to an example we have made, that a man of a most perfect natural disposition was born and that his mother died after she had suckled him for several months. And the man,1 alone in an isolated island, took upon himself the entire upbringing of him who was born, until he grew up, became intelligent, and acquired knowledge. Now this child had never seen a woman or a female of one of the species of the other animals. Accordingly he puts a question, saying to a man who is with him: How did we come to exist, and in what way were we generated? Thereupon the man to whom the question was put replied: Every individual among us was generated in the belly of an individual belonging like us to our species, an individual who is female and has such and such a form. Every individual among us was — being small in body — within the belly, was moved and fed there, and grew up little by little — being alive — until it reached such and such limit in size. Thereupon an opening was opened up for him in the lower part of the body, from which he issued and came forth. Thereupon he does not cease growing until he becomes such as you see that we are. Now the orphaned child must of necessity put the question: Did every individual among us — when he was little, contained within a belly, but alive and moving and growing — did he eat, drink, breathe through the mouth and nose, produce excrements? He is answered: No. Thereupon he indubitably will hasten to set this down as a lie and will produce a demonstration that all these true statements are impossible, drawing inferences from [35b] perfect beings that have achieved stability. He will say: If any individual among us were deprived of breath for the fraction of an hour, he would die and his movements would cease. How then can one conceive that an individual among us could be for months within a thick vessel surrounding him, which is within a body, and yet be alive and in motion? If one of us were to swallow a sparrow, that sparrow would die immediately upon entering the stomach, and all the more the underbelly. Every individual among us would undoubtedly perish within a few days if he did not eat food with his mouth and drink water; how then can an individual remain alive for months without eating and drinking? Every individual among us, if he had taken food and had not given off excrements, would die in very great pain within a few days; how then could the individual in question remain for months without giving off excrements? If the belly of one of us were perforated, he would die after some days; how then can it be supposed that the navel of the fetus in question was open? How is it that he does not open his eyes, put out his palms, stretch his feet, while all the parts of his body are whole and have no defect as you thought? Similarly all the analogies2 will be carried on in order to show that it is in no respect possible that man should be generated in that manner.
Consider this example and reflect upon it, you who are engaged in speculation, and you shall find that this is exactly our position with regard to Aristotle. For we, the community of the followers of Moses our Master and Abraham our Father, may peace be on them, believe that the world was generated in such and such manner and came to be in a certain state from another state and was created in a certain state, which came after another state. Aristotle, on the other hand, begins to contradict us and to bring forward against us proofs based on the nature of what exists, a nature that has attained stability, is perfect, and has achieved actuality. As for us, we declare against him that this nature, after it has achieved stability and perfection, does not resemble in anything the state it was in while in the state of being generated, and that it [36a] was brought into existence from absolute nonexistence.3 Now what argument from among all that he advances holds good against us? For these arguments necessarily concern only those4 who claim that the stable nature of that which exists, gives an indication of its having been created in time. I have already made it known to you that I do not claim this.
Now I shall go back and set forth for your benefit the principles of his methods and shall show you that nothing in them of necessity concerns us in any respect, since we contend that God brought the world as a whole into existence after nonexistence5 and formed it until it has achieved perfection as you see it. He said that the first matter is subject to neither generation nor passing-away and began to draw inferences in favor of this thesis from the things subject to generation and passing-away and to make clear that it was impossible that the first matter was generated. And this is correct. For we do not maintain that the first matter is generated as man is generated from the seed or that it passes away as man passes away into dust. But we maintain that God has brought it into existence from nothing and that after being brought into existence, it was as it is now — I mean everything is generated from it, and everything generated from it passes away into it; it does not exist devoid of form; generation and corruption terminate in it; it is not subject to generation as are the things generated from it, nor to passing-away as are the things that pass away into it, but is created from nothing.6 And its Creator may, if He wishes to do so, render it entirely and absolutely nonexistent. We likewise say the same thing of motion. For he has inferred from the nature of motion that motion is not subject to generation and passing-away. And this is correct. For we maintain that after motion has come into existence with the nature characteristic of it when it has become stable, one cannot imagine that it should come into being as a whole and perish as a whole, as partial motions come into being and perish. This analogy7 holds good with regard to everything that is attached [36b] to the nature of motion. Similarly the assertion that circular motion has no beginning is correct. For after the spherical body endowed with circular motion has been brought into being, one cannot conceive that its motion should have a beginning. We shall make a similar assertion with regard to the possibility that must of necessity precede everything that is generated. For this is only necessary in regard to this being that is stabilized — in this being everything that is generated, is generated from some being. But in the case of a thing created from nothing, neither the senses nor the intellect point to something that must be preceded by its possibility. We make a similar assertion with regard to the thesis that there are no contraries in heaven. That thesis is correct. However, we have not claimed that the heavens have been generated as the horse and palm tree are. Nor have we claimed that their being composite renders necessary their passing-away as is the case with plants and animals because of the contraries that subsist in them.
The essential point is, as we have mentioned, that a being’s state of perfection and completion furnishes no indication of the state of that being preceding its perfection. It involves no disgracefulness for us if someone says that the heavens were generated before the earth or the earth before the heavens or that the heavens have existed without stars or that a particular species of animals has existed without another species being in existence. For all this applies to the state of this universe when it was being generated. Similarly in the case of animals when they are being generated, the heart exists before the testicles — a circumstance that may be ocularly perceived — and the veins before the bones; and this is so in spite of the fact that after the animal has achieved perfection, no part of its body can exist in it if any part of all the others, without which the individual cannot possibly endure, does not exist.
All these assertions are needed if the text of Scripture is taken in its external sense, even though it must not be so taken, as shall be explained8 when we shall speak of it at length. [37a] You ought to memorize this notion. For it is a great wall that I have built around the Law, a wall that surrounds it warding off the stones of all those who project these missiles against it.
However, should Aristotle, I mean to say he who adopts his opinion, argue against us by saying: If this existent9 provides no indication for us, how do you know that it is generated and that there has existed another nature that has generated it — we should say: This is not obligatory for us in view of what we wish to maintain. For at present we do not wish to establish as true that the world is created in time. But what we wish to establish is the possibility of its being created in time. Now this contention cannot be proved to be impossible by inferences drawn from the nature of what exists, which we do not set at nought. When the possibility of this contention has been established, as we have made clear, we shall go back and we shall make prevail the opinion asserting creation in time.
In this question10 no way remains open to him except to show the impossibility for the world having been created in time, not by starting from the nature of being, but by starting from the judgments of the intellect with regard to the deity: these being the three methods that I have mentioned to you before.11 By means of these methods they12 wish to prove the eternity of the world, taking the deity as their starting point. I shall accordingly show you, in a following chapter, how doubts can be cast on these methods so that no proof whatever can be established as correct by means of them.
