Phaedo. By Zeus, said he, I am far from thinking that I know the cause of any of these things, I who do not even dare to say, when one is added to one, whether the one to which the addition was made has become two, or the one which was added, or the one which was added and the one to which it was added became two by the addition of each to the other. I think it is wonderful that when each of them was separate from the other, each was one and they were not then two, and when they were brought near each other this juxtaposition was the cause of their becoming two. And I cannot yet believe that if one is divided, the division causes it to become two; for this is the opposite of the cause which produced two in the former case; for then two arose because one was brought near and added to another one, and now because one is removed and separated from other. And I no longer believe that I know by this method even how one is generated or, in a word, how anything is generated or is destroyed or exists, and I no longer admit this method, but have another confused way of my own.Then one day I heard a man reading from a book, as he said, by Anaxagoras, that it is the mind that arranges and causes all things. I was pleased with this theory of cause, and it seemed to me to be somehow right that the mind should be the cause of all things, and I thought, If this is so, the mind in arranging things arranges everything and establishes each thing as it is best for it to be. So if anyone wishes to find the cause of the generation or destruction or existence of a particular thing, he must find out what sort of existence, or passive state of any kind, or activity is best for it. And therefore in respect to that particular thing, and other things too, a man need examine nothing but what is best and most excellent; for then he will necessarily know also what is inferior, since the science of both is the same. As I considered these things I was delighted to think that I had found in Anaxagoras a teacher of the cause of things quite to my mind, and I thought he would tell me whether the earth is flat or round, and when he had told me that, would go on to explain the cause and the necessity of it, and would tell me the nature of the best and why it is best for the earth to be as it is; and if he said the earth was in the center, he would proceed to show that it is best for it to be in the center; and I had made up my mind that if he made those things clear to me, I would no longer yearn for any other kind of cause.
