as one says. For thus envy, and fear, and anger, and lust affect one. During the daytime, indeed, vice looks abroad and imitates the behaviour of others, is shy and conceals its evil desires, and does not altogether give way to its propensities, but often even resists and fights stoutly against them; but in sleep it escapes the observation of people and the law, and, being as far as possible removed from fear or modesty, gives every passion play, and excites its depravity and licentiousness, for, to borrow Plato's expression,[217] "it attempts incest with its mother, and procures for itself unlawful meats, and abstains from no action whatever," and enjoys lawlessness as far as is practicable in visions and phantasies, that end in no complete pleasure or satisfaction, but can only stir up and inflame the passions and morbid emotions. Sec. III. Where then is the pleasure of vice, if there is nowhere in it freedom from anxiety and pain, or independence, or tranquillity, or rest?[218] A healthy and sound constitution does indeed augment the pleasures of the body, but for the soul there can be no lasting joy or gratification, unless cheerfulness and fearlessness and courage supply a calm serenity free from storms; for otherwise, even if hope or delight smile on the soul, it is soon confused and disturbed by care lifting up its head again, so that it is but the calm of a sunken rock. Sec. IV. Pile up gold, heap up silver, build covered walks, fill your house with slaves and the town with debtors, unless you lay to rest the passions of the soul, and put a curb on your insatiable desires, and rid yourself of fear and anxiety, you are but pouring out wine for a man in a fever, and giving honey to a man who is bilious, and laying out a sumptuous banquet for people who are suffering from dysentery, and can neither retain their food nor get any benefit from it, but are made even worse by it. Have you never observed how sick persons turn against and spit out and refuse the daintiest and most costly viands, though people offer them and almost force them down their throats, but on another occasion, when their condition is different, their respiration good, their blood in a healthy state, and their natural warmth restored, they get up, and enjoy and make a good meal of simple bread and cheese and cress? Such, also, is the effect of reason on the mind. You will be contented, if you have learned what is good and honourable. You will live daintily and be a king in poverty, and enjoy a quiet and private life as much as the public life of general or statesman. By the aid of philosophy you will live not unpleasantly, for you will learn to extract pleasure from all places and things: wealth will make you happy, because it will enable you to benefit many; and poverty, as you will not then have many anxieties; and glory, for it will make you honoured; and obscurity, for you will then be safe from envy.
