Section 10: Virtue Must Lead, Not Follow explained simply

X. “You purposely misunderstand what I say,” says he, “for I too say that no one can live pleasantly unless he lives honorably also, and this cannot be the case with dumb animals who measure the extent of their happiness by that of their food. I loudly and publicly proclaim that what I call a pleasant life cannot exist without the addition of virtue.” Yet who does not know that the greatest fools drink the deepest of those pleasures of yours? or that vice is full of enjoyments, and that the mind itself suggests to itself many perverted, vicious forms of pleasure?—in the first place arrogance, excessive self-esteem, swaggering precedence over other men, a shortsighted, nay, a blind devotion to his own interests, dissolute luxury, excessive delight springing from the most trifling and childish causes, and also talkativeness, pride that takes a pleasure in insulting others, sloth, and the decay of a dull mind which goes to sleep over itself. All these are dissipated by virtue, which plucks a man by the ear, and measures the value of pleasures before she permits them to be used; nor does she set much store by those which she allows to pass current, for she merely allows their use, and her cheerfulness is not due to her use of them, but to her moderation in using them. “Yet when moderation lessens pleasure, it impairs the highest good.” You devote yourself to pleasures, I check them; you indulge in pleasure, I use it; you think that it is the highest good, I do not even think it to be good: for the sake of pleasure I do nothing, you do everything.
