"Tell me, Eutydemus, thinkest thou not that liberty is a precious and honorable thing for an individual and for a State?--It is the most precious of all.--Thinkest thou him then who allows himself to be overruled by the pleasures of the body, and thereby disabled from doing good, a free man?--Not the least.--Perhaps callest thou liberty the power to do good, and servitude the being prevented from it by obstacles.--Precisely.--The intemperate then appear to thee as slaves?--Yes, by Jupiter, and rightly so.--What thinkest thou of masters who hinder the doing good, and oblige one to do wrong.--It is, by Jupiter, the worst possible kind.--And which is the worst of servitudes?--To my mind that which subjects us to the worst masters.--Then is intemperance the worst of servitudes?--So I think." Plato, on his side, in a charming picture brings out with force the insatiableness of sensual passions: "See," says Socrates, "if the temperate man and the disorderly man are not like two men having each a large number of casks: the casks of the one are in good condition and full, one with wine, another with honey, a third with milk, and others with other liquors; these liquors, moreover, are rare and hard to get; they cost infinite trouble to obtain; their owner having once filled his barrels, pours henceforth nothing more into them; he has no longer any anxiety concerning them, and is perfectly at ease. The other can, it is true, procure the same liquors, but only with difficulty; his casks, moreover, being leaky and rotten, he is obliged to fill them constantly, day and night, lest he be devoured by burning pains. This picture being an image of both lives, canst thou say that that of the libertine is happier than that of the temperate man?"
