"So these common meals, for example, and these gymnasia, while they are at present beneficial to the Poleis in many other respects, yet in the event of civil strife they prove dangerous (as is shown by the case of the youth of Miletus, Boeotia and Thurii); and, moreover, this institution, when of old standing, is thought to have corrupted the pleasures of love which are natural not to men only but also natural to beasts. For this your Poleis are held primarily responsible, and along with them all others that especially encourage the use of gymnasia. And whether one makes the observation in earnest or in jest, one certainly should not fail to observe that when male unites with female for procreation the pleasure experienced is held to be due to nature, but contrary to nature when male mates with male or female with female, and that those first guilty of such enormities were impelled by their slavery to pleasure. And we all accuse the Cretans of concocting the story about Ganymede." - Plato, Laws.
