Thales the Milesian doth affirm that water is the principle whence all things in the universe spring. This person appears to be the first of philosophers; from him the Ionic sect took its denomination, for there are many families and successions amongst philosophers. After he had professed philosophy in Egypt, when he was very old, he returned to Miletus. He pronounced, that all things had their original from water, and into water all things are resolved. His first reason was, that whatsoever was the prolific seed of all animals was a principle, and that is moist; so that it is probable that all things receive their original from humidity. His second reason was, that all plants are nourished and fructified by that thing which is moist, of which being deprived they wither away. Thirdly, that that fire of which the sun and stars are made is nourished by watery exhalations,—yea, and the world itself; which moved Homer to sing that the generation of it was from water:— The ocean is Of all things the kind genesis.[36] Anaximander, who himself was a Milesian, assigns the principle of all things to the Infinite, from whence all things flow, and into the same are corrupted; hence it is that infinite worlds are framed, and those vanish again into that whence they have their original. And thus he farther proceeds, For what other reason is there of an Infinite but this, that there may be nothing deficient as to the generation or subsistence of what is in nature? There is his error, that he doth not acquaint us what this Infinite is, whether it be air, or water, or earth, or any other such like body. Besides he is peccant, in that, giving us the material cause, he is silent as to the efficient cause of beings; for this thing which he makes his Infinite can be nothing but matter; but operation cannot take place in the sphere of matter, except an efficient cause be annexed. Anaximenes his fellow-citizen pronounceth, that air is the principle of all beings; from it all receive their original, and into it all return. He affirms that our soul is nothing but air; it is that which constitutes and preserves; the whole world is invested with spirit and air. For spirit and air are synonymous. This person is in this deficient, that he concludes that of pure air, which is a simple body and is made of one only form, all animals are composed. It is not possible to think that a single principle should be the matter of all things, from whence they receive their subsistence; besides this there must be an operating cause. Silver (for example) is not of itself sufficient to frame a drinking cup; an operator also is required, which is the silversmith. The like may be applied to vessels made of wood, brass, or any other material.
