A happy life consists in a mind which is free, upright, undaunted, and stedfast beyond the influence of fear or desire, which thinks nothing good except honor, and nothing bad except shame, and regards everything else as a mass of mean details which can neither add anything to nor take anything away from the happiness of life, but which come and go without either increasing or diminishing the highest good? A man of these principles, whether he will or no, must be accompanied by a continual cheerfulness, a high happiness, which comes indeed from on high because he delights in what he has, and desires no greater pleasures than those which his home affords. Is he not right in allowing these to turn the scale against petty, ridiculous, and short-lived movements of his wretched body? on the day on which he becomes proof against pleasure he also becomes proof against pain. See, on the other hand, how evil and guilty a slavery a man is forced to serve who is dominated in turn by pleasures and pains, those most untrustworthy and passionate of masters. We must, therefore, escape from them into freedom. This nothing will bestow upon us save contempt of Fortune; but if we attain to this, then there will dawn upon us those invaluable blessings, the repose of a mind that is at rest in a safe haven, its lofty imaginings, its great and steady delight at casting out errors and learning to know the truth, its courtesy and its cheerfulness, in all of which we shall take delight, not regarding them as good things, but as proceeding from the proper good of man.... 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 can not 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....
