[66] And it was on this account that of all living creatures God created fishes first, inasmuch as they partake of corporeal substance in a greater degree than they partake of soul, being in a manner animals and not animals, moving soulless things, having a sort of semblance of soul diffused through them for no object beyond that of keeping their bodies alive (just as they say that salt preserves meat), in order that they may not easily be destroyed. And after the fishes, he created winged and terrestrial animals: for these are endowed with a higher degree of sensation, and from their formation show that the properties of their animating principle are of a higher order. But after all the rest, then, as has been said before, he created man, to whom he gave that admirable endowment of mind—the soul, if I may so call it, of the soul, as being like the pupil to the eye; for those who most accurately investigate the natures of things affirm, that it is the pupil which is the eye of the eye.
