He may perhaps construe the shaft, which after all is neither very obscure nor very veiled, and answer, 'It is you who have no intellect: I have more than all your sort. '
? ? ? ? ? ? ? . You will, then, credit him no more than you would a blind man who retorted that it is you who are blind, and that he sees much better than all those who believe they see like you.
? ? ? ? ? ? ? . You have said enough to demonstrate in more detail than I have ever heard what the word 'matter' means and what must be understood by 'matter' in natural things. In the same way Timaeus the Pythagorean13 teaches us to find, through the metamorphosis of one element into another, the matter that is hidden and that can be known only in analogical terms. 'Where the form of the earth was', he says, 'there afterwards appeared the form of the water', and here we cannot say that one form receives the other, because a contrary thing does not accept or receive another. That is, the dry does not receive the wet, or rather the dryness does not receive the wetness, but there is a third thing from which the dryness is expelled and into which wetness is introduced, and this third thing is the substratum of both con- traries, not being itself contrary to any. It follows that, since we cannot think of the earth as reduced to nothing, we must conjecture that something which was in the earth has subsisted and is found in the water. For the same reason, that same thing will subsist and will be found in the air, when the water is transmuted into air (under the effect of the heat which reduces it to fumes or vapour).
? ? ? ? ? ? ? . Fromthiswemayconclude(inspiteofouradversaries)that nothing is ever annihilated and loses its being, except for the external and material accidental form. That is why both the matter and the substantial form of any natural thing whatever (that is, its soul) can be neither destroyed nor annihilated, losing their being completely. Certainly this cannot be true of all the substantial forms of the Peripatetics and others like them, which consist of nothing but a certain complexion and a certain set of accidents; all that they are able to designate outside of their primary matter is nothing but accident, complexion, disposition of qualities, a prin- ciple of definition, quiddity. Hence, some cowled and subtle metaphysi- cians among them14, wishing to excuse rather than accuse their idol Aristotle, have come up with humanity, bovinity, oliveness as specific sub- stantial forms. This humanity - for example, Socratiety - this bovinity, this
? ? ?

? horseness, are individual substances. They have come up with all that in order to provide a substantial form which merits the name of substance, just as matter has the name of substance, and the being of substance. They have never derived any gain from this, for if you ask them, point by point, 'In what does the the substantial being of Socrates consist? ', they will answer, 'In Socrateity'; if you then ask, 'What do you mean by Socrateity? ', they will answer, 'The substantial form and proper matter of Socrates. ' But let us leave aside this substance which is matter, and ask, 'What is the substance as form? ' Some of them will reply, 'It is its soul'. Ask them, 'What is this soul? ' If they say it is the entelechy and perfection of a body possessing potential life, remark that this is an accident. If they say it is a principle of life, sense, vegetation and intellect, remark that, although that principle is a substance if one considers it fundamentally, as we do, they present it as only an accident. For the fact of being a principle of such and such a thing does not express an absolute and substantial nature, but a nature that is accidental and relative to that which is principled: just as whoever says what I do or can do is not expressing my being and substance; that would be expressed by who says what I am, insofar as I am myself, con- sidered absolutely. You see, then, how they consider this substantial form which is the soul: even if they have chanced to recognize it as substance, they have never, however, designated or considered it as such. You can make this conclusion out more plainly if you ask them in what consists the substantial form of an inanimate thing, for example, that of wood: the most subtle will imagine that it consists in woodness. Now take away that mate- rial common to iron, to wood, to stone, and ask, 'What substantial form of iron remains? ' They will never point out anything but accidents. And these are among the principles of individuation, and provide particularity, because the material cannot be contained within the particular except through some form, and because this form is the constituent principle of some substance, they hold that it is substantial, but then they cannot show it physically except as something accidental. When they have finally done all they can, they are left with a substantial form which exists only logically and not in nature. Thus, a logical construction comes to be posited as the principle of natural things.
? ? ? ? ? ? ? . Aristotle does not realize this?
? ? ? ? ? ? ? . I believe he fully realized it but could do nothing about it. This is why he says that the ultimate differences are unknown and cannot be expressed.

? ? ? ? ? ? ? ? . Then, he seems to me to have openly confessed his igno- rance; therefore, I would be of the opinion that it is better to embrace those philosophical principles which, in this important question, do not plead ignorance, such as those of Pythagoras, Empedocles and your Nolan, whose opinions we touched on yesterday.
? ? ? ? ? ? ? . This is what the Nolan holds: there is an intellect that gives being to everything, which the Pythagoreans and the Timaeus call the 'giver of forms'; a soul and a formal principle which becomes and informs everything, that they call 'fountain of forms'; there is matter, out of which everything is produced and formed, and which is called by everyone the 'receptacle of forms'.
? ? ? ? ? ? ? . This doctrine, from which it seems nothing is lacking, pleases me much. And, indeed, it is necessary that, just as we can posit a constant and eternal material principle, we similarly posit a formal princi- ple. We see that all natural forms cease in matter, then appear again in mat- ter; therefore, nothing, if not matter, seems in reality to be constant, firm, eternal and worthy to be considered as principle. Besides, forms do not exist without matter, in which they are generated and corrupted, and out of whose bosom they spring and into which they are taken back. Hence, matter, which always remains fecund and the same, must have the funda- mental prerogative of being recognized as the only substantial principle; as that which is, and forever remains, and all the forms together are to be taken merely as varied dispositions of matter, which come and go, cease and renew themselves, so that none have value as principle. This is why we find philosophers who, having pondered thoroughly the essence of natural forms, such as one may see in Aristotle and his kind, have finally concluded that they are only accidents and particularities of matter, so that, accord- ing to them, it is to matter that we must accord the privilege of being act and perfection, and not to the things of which we can truly say that they are neither substance nor nature, but relative to the substance and nature - that is to say, in their opinion, matter, which for them is a necessary, eter- nal and divine principle, as it is to Avicebron, the Moor, who calls it 'God who is in everything'.
? ? ? ? ? ? ? . Those who have not recognized any other form outside of accidental form have been led to this error, and this Moor, although he had accepted the substantial form from the Peripatetic doctrine in which he was nurtured, judged it corruptible and not merely susceptible to material mutations. Since he despised that which is produced and does not produce,
? ?
Cause, principle and unity
? is constituted and does not constitute, is remade but does not remake, he held it worthless compared to matter, which is stable, eternal, progenitor and mother. And this happens, inevitably, to those who do not know what wedo.
? ? ? ? ? ? ? . Thepointhasbeenverywellexamined. Butitistimetoturn from this digression back to our problem. We now know how to distinguish matter from form, as much from the accidental form (whatever it may be) as from the substantial form. We must still look into its nature and its real- ity. But first, I would like to know whether, in view of the great union that this world soul and universal form has with matter, one could not admit that other mode of philosophizing, belonging to those who do not separate the act from the essence of matter, and who understand matter as a divine thing, and not as something so pure and formless that it cannot form and clothe itself.
? ? ? ? ? ? ? . It is not easy, because absolutely nothing operates on itself alone, and there is always some distinction between an agent and what is produced or that on which the action and operation work. For that reason, it is good to distinguish matter from soul in the body of nature, and in the soul to distinguish the idea of the species. 15 Hence we affirm that in this body there are three things: first, the universal intellect inherent in things; second, the soul that vivifies all; and third, the substratum. But we shall not refuse the name of philosopher to someone who follows his own bent and takes this formed body, or (as we prefer to call it) this rational animal, and then begins to take as first principle, in some sense, the constituents of this body, such as air, earth, fire, or even the ethereal region and the astral region, or spirit and body, or the void and the plenum (though not the void in Aristotle's sense), or yet another convenient way. Such a philosophy, it seems to me, does not deserve to be repudiated, especially when, no mat- ter what basis is presupposed or what form of construction is contem- plated, it helps to improve speculative science and knowledge of natural things, as was, indeed, done by many ancient philosophers. For it is a sign of an ambitious, presumptuous, envious and vain mind to wish to persuade others that there is only one way to investigate and to attain knowledge of nature, and it is the sign of a madman or man without reason to believe that this way lies within himself alone. So that, although we should always rather prefer, honour and practise the most resolute and constant, the most contemplative and dignified way, and the most lofty method of inquiry, we 15 The universal intellect, mentioned in the following sentence.

I accept that other method which proceeds alchemically, extracting the quintessences, and using fire to volatilize mercury, deposit salt, make sulphur grow luminous or extract oil from composites. But I do not wish to determine what method is the best among so many medical procedures.
