Now Plato in conceiving his theory of Ideas saysCf. Phaedo, 96 b (I considered) whether it is blood or air or fire with which we think, or none of these things, but the brain which furnishes the senses of hearing and sight and smell, and from these arise memory and opinion, and from memory and opinion, when they have become stable, in the same way knowledge arises.: Since there is such a thing as memory, there must be ideas present in things, because memory is of something stable and permanent, and nothing is permanent except the ideas. For how, he says, could animals have survived unless they had apprehended the idea and had been endowed by Nature with intelligence to that end? As it is, they remember similarities and what their food is like, which shows that animals have the innate power of discerning what is similar. And hence they perceive others of their own kind. How then does Epicharmus put it?
