Soc. This, then, is precisely the question which the previous discussion puts to us: How is each of them one and many, and how is it that they are not immediately infinite, but each possesses a definite number, before the individual phenomena become infinite? Pro. Philebus, somehow or other Socrates has led us round and plunged us into a serious question. Consider which of us shall answer it. Perhaps it is ridiculous that I, after taking your place in entire charge of the argument, should ask you to come back and answer this question because I cannot do so, but I think it would be still more ridiculous if neither of us could answer. 
 Consider, then, what we are to do. For I think Socrates is asking us whether there are or are not kinds of pleasure, how many kinds there are, and what their nature is, and the same of wisdom. Soc. You are quite right, son of Callias; for, as our previous discussion showed, unless we can do this in the case of every unity, every like, every same, and their opposites, none of us can ever be of any use in anything. 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. Soc. What way do you mean?
