e determined rightly both how many and of what sort the causes are. Besides this it is plain that when the causes are being looked for, either all four must be sought thus or they must be sought in one of these four ways. Let us next discuss the possible difficulties with regard to the way in which each of these thinkers has spoken, and with regard to his situation relatively to the first principles.
Book I Chapter 8
Those, then, who say the universe is one and posit one kind of thing as matter, and as corporeal matter which has spatial magnitude, evidently go astray in many ways. For they posit the elements of bodies only, not of incorporeal things, though there are also incorporeal things. And in trying to state the causes of generation and destruction, and in giving a physical account of all things, they do away with the cause of movement. Further, they err in not positing the substance, i.e. the essence, as the cause of anything, and besides this in lightly calling any of the simple bodies except earth the first principle, without inquiring how they are produced out of one anothers-I mean fire, water, earth, and air. For some things Dame Adidas Hoodies&Track Tops are produced out of each other by combination, others by separation, and this makes the greatest difference to Adidas Superstar Metal their priority and posteriority. For (1) in a way the property of being most elementary of all would seem to belong to the first thing from which Men Slim-Fit Jeans they are produced by combination, and this property would belong to the most fine-grained and subtle of bodies. For this reason those who make fire the principle would be most in agreement with this argument. But each of the other thinkers agrees that the element of corporeal things is of this sort. At least none of those who named one element claimed that earth was the element, evidently because of the coarseness of its grain. (Of the other three elements each has Men Track Pants found some judge on its Converse High Tops side; for some maintain that fire, others that water, others that air is the element. Yet why, after all, do they not name earth also, as most men do? For people Men Lightweight Jackets say all things are earth Hesiod says earth was produced first of corporeal things; so primitive and popular has the opinion been.) According to this argument, then, no one would be right who either says the first principle is any of the elements other than fire, or supposes it to be denser than air but rarer than water. But Adidas ZX10000 (2) if that which Damskie Vans Era is later in generation is prior Men Denim Jackets in nature, and that which is concocted and compounded is later in generation, the contrary of what we have been saying must be Dame true,-water must be prior to air, and earth to water.
So much, then, for those who posit one cause such as we mentioned; but the same is true if one supposes more of these, as Empedocles says matter of things is four bodies. For he Adidas ZX750 too is confronted by consequences some of which are the same as have been mentioned, while others are peculiar to him. For we see these bodies Unisex produced from one another, which implies that the same body does not always remain fire or earth (we have spoken about thlinks:
