(131.) Power, favour, genius, riches, dignity, nobility, force, industry, capacity, virtue, vice, weakness, stupidity, poverty, impotence, plebeianism, and servility generally are combined in men in endless variety. These qualities mixed together in a thousand various manners, and compensating one another in many ways, form the different states and conditions of human life. Moreover, people who are acquainted with each otherʼs strength and weakness act reciprocally, for they believe it their duty; they know their equals, are conscious that some men are their superiors, and that they are superior to some others; and hence familiarity, respect or deference, pride or contempt. This is the reason why, in places of public resort, we see each moment some persons we wish to accost or bow to, and others we pretend not to know, and still less desire to meet; and why we are proud of being with the first and ashamed of the others. Hence it even happens that the very person with whom you think it an honour to be seen, and with whom you are desirous to converse, deems you troublesome and leaves you; and that often the very person who blushes when he meets others, receives the same treatment when others meet him, and that a man who treated others with contempt is himself disdained, for it is common enough to despise those who despise us. How wretched is such a behaviour; and since it is certain that in this strange interchange we gain on one side what we lose on another, should we not do better to abandon all haughtiness and pride, qualities so unsuited to frail humanity, and make an arrangement to treat one another with mutual kindness, by which we should at once gain the advantage of never being mortified ourselves, and the happiness, which is just as great, of never mortifying others? (132.) Instead of being frightened, or even ashamed, at being called a philosopher, everybody in this world ought to have a strong tincture of philosophy;[589] it suits every one: its practice is useful to people of all ages, sexes, and conditions; it consoles us for the happiness of others, for the promotion of those whom we think undeserving, for failures, and decay of strength and beauty; it steels us against poverty, age, sickness, and death, against fools and buffoons; it will help us to pass away our life without a wife, or to bear with the one with whom we have to live. (133.) Men are one hour overjoyed at trifles, and the next overcome with grief for a mere disappointment; nothing is more unequal and incoherent than the emotions stirring their hearts and minds in so short a time. If they would set no higher value on the things of this world than they really deserve, this evil would be cured. (134.) It is as difficult to find a vain man who believes himself as happy as he deserves, as a modest man who believes himself too unhappy.
