DIADUMENUS. These things they hold against the common conceptions; but those which follow they hold also against their own, engendering that which is most hot by refrigeration, and that which is most subtile by condensation. For the soul, to wit, is a substance most hot and most subtile. But this they make by the refrigeration and condensation of the body, changing, as it were, by induration the spirit, which of vegetative is made animal. Moreover, they say that the sun became animated, his moisture changing into intellectual fire. Behold how the sun is imagined to be engendered by refrigeration! Xenophanes indeed, when one told him that he had seen eels living in hot water, answered, We will boil them then in cold. But if these men engender heat by refrigeration and lightness by condensation, it follows, they must also generate cold things by heat, thick things by dissolution, and heavy things by rarefaction, that so they may keep some proportion in their absurdity.
