For there is either a dispersion of the elements out of which everything has been compounded, or a change from the solid to the earthy and from the airy to the aerial, so that these parts are taken back into the universal reason, whether this at certain periods is consumed by fire or renewed by eternal changes. And do not imagine that the solid and the airy part belong to thee from the time of generation. For all this received its accretion only yesterday and the day before, as one may say, from the food and the air which is inspired. This, then, which has received the accretion, changes, not that which thy mother brought forth. But suppose that this which thy mother brought forth implicates thee very much with that other part, which has the peculiar quality of change, this is nothing in fact in the way of objection to what is said.
