Soc. I did not introduce this question on Philebus’ account; but unless we consider these pleasures and those that follow in their train, Protarchus, we can probably never settle the point at issue.

Pro. Then we must attack this family of pleasures.

Soc. You mean those which are mixed?

Pro. Certainly.

Soc. Some mixtures are concerned with the body and are in the body only, and some belong only to the soul and are in the soul; and we shall also find some mingled pains and pleasures belonging both to the soul and to the body, and these are sometimes called pleasures, sometimes pains.

Pro. How so?

Soc. Whenever, in the process of restoration or destruction, anyone has two opposite feelings, as we sometimes are cold, but are growing warm, or are hot, but are growing cold, the desire of having the one and being free from the other, the mixture of bitter and sweet, as they say, joined with the difficulty in getting rid of the bitter, produces impatience and, later, wild excitement.

Pro. What you say is perfectly true.

Soc. And such mixtures sometimes consist of equal pains and pleasures and sometimes contain more of one or the other, do they not?

Pro. Of course.

Soc. In the case of the mixtures in which the pains are more than the pleasures—say the itch, which we mentioned just now, or tickling—when the burning inflammation is within and is not reached by the rubbing and scratching, which separate only such mixtures as are on the surface, sometimes by bringing the affected parts to the fire or to something cold we change from wretchedness to inexpressible pleasures, and sometimes the opposition between the internal and the external produces a mixture of pains and pleasures, whichever happens to preponderate; this is the result of the forcible separation of combined elements, or the combination of those that were separate, and the concomitant juxtaposition of pains and pleasures.
