Protarchus
Pro. That, Socrates, seems pretty likely to be true. However, it is splendid for the wise man to know everything, but the next best thing, it seems, is not to be ignorant of himself. I will tell you why I say that at this moment. You, Socrates, have granted to all of us this conversation and your cooperation for the purpose of determining what is the best of human possessions. For when Philebus said it was pleasure and gaiety and enjoyment and all that sort of thing, you objected and said it was not those things, but another sort, and we very properly keep reminding ourselves voluntarily of this, in order that both claims may be present in our memory for examination. You, as it appears, assert that the good which is rightly to be called better than pleasure is mind, knowledge, intelligence, art, and all their kin; you say we ought to acquire these, not that other sort. When those two claims were made and an argument arose, we playfully threatened that we would not let you go home until the discussion was brought to some satisfactory conclusion. You agreed and put yourself at our disposal for that purpose. Now, we say that, as children put it, you cannot take back a gift once fairly given. So cease this way of meeting all that we say.
