Section 7: Pleasure Can Become Slavery explained simply

VII. Even those very people who declare the highest good to be in the belly, see what a dishonourable position they have assigned to it: and therefore they say that pleasure cannot be parted from virtue, and that no one can either live honourably without living cheerfully, nor yet live cheerfully without living honourably. I do not see how these very different matters can have any connexion with one another. What is there, I pray you, to prevent virtue existing apart from pleasure? of course the reason is that all good things derive their origin from virtue, and therefore even those things which you cherish and seek for come originally from its roots. Yet, if they were entirely inseparable, we should not see some things to be pleasant, but not honourable, and others most honourable indeed, but hard and only to be attained by suffering. Add to this, that pleasure visits the basest lives, but virtue cannot co-exist with an evil life; yet some unhappy people are not without pleasure, nay, it is owing to pleasure itself that they are unhappy; and this could not take place if pleasure had any connexion with virtue, whereas virtue is often without pleasure, and never stands in need of it. Why do you put together two things which are unlike and even incompatible one with another? 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 market-place, 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.
