Jowett: natural pleasure

Ath. There seems to be a difficulty, Stranger, with regard to states, in making words and facts coincide so that there can be no dispute about them. As in the human body, the regimen which does good in one way does harm in another ; and we can hardly say that any one course of treatment is adapted to a particular constitution. Now the gymnasia and common meals do a great deal of good, and yet they are a source of evil in civil troubles ; as is shown in the case of the Milesian, and Boeotian, and Thurian youth, among whom these institutions seem always to have had a tendency to degrade the ancient and natural custom of love below the level, not only of man, but of the beasts. The charge may be fairly brought against your cities above all others, and is true also of most other states which especially cultivate gymnastics. Whether such matters are to be regarded jestingly or seriously, I think that the pleasure is to be deemed natural which arises out of the intercourse between men and women ; but that the intercourse of men with men, or of women with women, is contrary to nature, and that the bold attempt was originally due to unbridled lust. The Cretans are always accused of having invented the story of Ganymede and Zeus because they wanted to justify themselves in the enjoyment of unnatural pleasures by the practice of the god whom they believe to have been their lawgiver. Leaving the story, we may observe that any speculation about laws turns almost entirely on pleasure and pain, both in states and in individuals : these are two fountains which nature lets flow, and he who draws from them where and when, and as much as he ought, is happy ; and this holds of men and animals — of individuals as well as states ; and he who indulges in them ignorantly and at the wrong time, is the reverse of happy.
