[Footnote 1: Let me remark that people in the highest positions in life, with all their brilliance, pomp, display, magnificence and general show, may well say:--Our happiness lies entirely outside us; for it exists only in the heads of others.] At all events, a man is in a very bad way, who finds no source of happiness in the first two classes of blessings already treated of, but has to seek it in the third, in other words, not in what he is in himself, but in what he is in the opinion of others. For, after all, the foundation of our whole nature, and, therefore, of our happiness, is our physique, and the most essential factor in happiness is health, and, next in importance after health, the ability to maintain ourselves in independence and freedom from care. There can be no competition or compensation between these essential factors on the one side, and honor, pomp, rank and reputation on the other, however much value we may set upon the latter. No one would hesitate to sacrifice the latter for the former, if it were necessary. We should add very much to our happiness by a timely recognition of the simple truth that every man's chief and real existence is in his own skin, and not in other people's opinions; and, consequently, that the actual conditions of our personal life,--health, temperament, capacity, income, wife, children, friends, home, are a hundred times more important for our happiness than what other people are pleased to think of us: otherwise we shall be miserable. And if people insist that honor is dearer than life itself, what they really mean is that existence and well-being are as nothing compared with other people's opinions. Of course, this may be only an exaggerated way of stating the prosaic truth that reputation, that is, the opinion others have of us, is indispensable if we are to make any progress in the world; but I shall come back to that presently. When we see that almost everything men devote their lives to attain, sparing no effort and encountering a thousand toils and dangers in the process, has, in the end, no further object than to raise themselves in the estimation of others; when we see that not only offices, titles, decorations, but also wealth, nay, even knowledge[1] and art, are striven for only to obtain, as the ultimate goal of all effort, greater respect from one's fellowmen,--is not this a lamentable proof of the extent to which human folly can go? To set much too high a value on other people's opinion is a common error everywhere; an error, it may be, rooted in human nature itself, or the result of civilization, and social arrangements generally; but, whatever its source, it exercises a very immoderate influence on all we do, and is very prejudicial to our happiness. We can trace it from a timorous and slavish regard for what other people will say, up to the feeling which made Virginius plunge the dagger into his daughter's heart, or induces many a man to sacrifice quiet, riches, health and
