virtue is a lofty quality, sublime, royal, unconquerable, untiring: pleasure is low, slavish, weakly, perishable; its haunts and homes are the brothel and the tavern. You will meet virtue in the temple, the marketplace, the senate house, manning the walls, covered with dust, sunburnt, horny-handed: you will find pleasure skulking out of sight, seeking for shady nooks at the public baths, hot chambers, and places which dread the visits of the aedile, soft, effeminate, reeking of wine and perfumes, pale or perhaps painted and made up with cosmetics. The highest good is immortal: it knows no ending, and does not admit of either satiety or regret: for a right-thinking mind never alters or becomes hateful to itself, nor do the best things ever undergo any change: but pleasure dies at the very moment when it charms us most: it has no great scope, and therefore it soon cloys and wearies us, and fades away as soon as its first impulse is over: indeed, we cannot depend upon anything whose nature is to change. Consequently it is not even possible that there should be any solid substance in that which comes and goes so swiftly, and which perishes by the very exercise of its own functions, for it arrives at a point at which it ceases to be, and even while it is beginning always keeps its end in view.
