Soc. Then let us begin with the goddess herself, of whom Philebus says that she is called Aphrodite, but that her real name is Pleasure.
Pro. Very good.
Soc. The awe which I always feel, Protarchus, about the names of the gods is more than human — it exceeds all other fears. And now I would not sin against Aphrodite by naming her amiss ; let her be called what she pleases. But Pleasure I know to be manifold, and with her, as I was just now saying, we must begin, and consider what her nature is. She has one name, and therefore you would imagine that she is one ; and yet surely she takes the most varied and even unlike forms. For do we not say that the intemperate has pleasure, and that the temperate has pleasure in his very temperance — that the fool is pleased when he is full of foolish fancies and hopes, and that the wise man has pleasure in his wisdom ? and how foolish would any one be who affirmed that all these opposite pleasures are severally alike !
Pro. Why, Socrates, they are opposed in so far as they spring from opposite sources, but they are not in themselves opposite. For must not pleasure be of all things most absolutely like pleasure — that is, like himself ?
Soc. Yes, my good friend, just as colour is like colour ; — in so far as colours are colours, there is no difference between them ; and yet we all know that black is not only unlike, but even absolutely opposed to white : or again, as figure is like figure, for all figures are comprehended under one class ; and yet particular figures may be absolutely opposed to one another, and there is an infinite diversity of them. And we might find similar examples in many other things ; therefore do not rely upon this argument, which would go to prove the unity of the most extreme opposites. And I suspect that we shall find a similar opposition among pleasures.
Pro. Very likely ; but how will this invalidate the argument ?
Soc. Why, I shall reply, that dissimilar as they are, you apply to them a now predicate, for you say that all pleasant things are good ; now although no one can argue that pleasure is not pleasure, he may argue, as we are doing, that pleasures are oftener bad than good ; but you call them all good, and at the same time are compelled, if you are pressed, to acknowledge that they are unlike. And so you must tell us what is the identical quality existing alike in good and bad pleasures, which makes. you designate all of them as good.
Pro. What do you mean, Socrates ? Do you think that any one who asserts pleasure to be the good, will tolerate the notion that some Pleasures are good and others bad ?
Soc. And yet you will acknowledge that they are different from one another, and sometimes opposed ?
Pro. Not in so far as they are pleasures.
Soc. That is a return to the old position, Protarchus, and so we are to say (are we ?) that there is no difference in pleasures, but that they are all alike ; and the examples which have just been cited do not pierce our dull minds, but we go on arguing all the same, like the weakest and most inexperienced reasoners ?
Pro. What do you mean ?
Soc. Why, I mean to say, that in self-defence I may, if I like, follow your example, and assert boldly that the two things most unlike are most absolutely alike ; and the result will be that you and I will prove ourselves to be very tyros in the art of disputing ; and the argument will be blown away and lost. Suppose that we put back, and return to the old position ; then perhaps we may come to an understanding with one another.
