Schopenhauer

“On a cold winter’s day, a group of porcupines huddled together to stay warm and keep from freezing. But soon they felt one another’s quills and moved apart. When the need for warmth brought them closer together again, their quills again forced them apart. They were driven back and forth at the mercy of their discomforts until they found the distance from one another that provided both a maximum of warmth and a minimum of pain. In human beings, the emptiness and monotony of the isolated self produces a need for society. This brings people together, but their many offensive qualities and intolerable faults drive them apart again. The optimum distance that they finally find that permits them to coexist is embodied in politeness and good manners. Because of this distance between us, we can only partially satisfy our need for warmth, but at the same time, we are spared the stab of one another’s quills.”

“In fact, the conviction that the world and man is something that had better not have been, is of a kind to fill us with indulgence towards one another. Nay, from this point of view, we might well consider the proper form of address to be, not Monsieur, Sir, mein Herr, but my fellow-sufferer, Soci malorum, compagnon de miseres!”

“When one considers how vast and how close to us is the problem of existence—this equivocal, tortured, fleeting, dream-like existence of ours—so vast and so close that a man no sooner discovers it than it overshadows and obscures all other problems and aims; and when one sees how all men, with few and rare exceptions, have no clear consciousness of the problem, nay, seem to be quite unaware of its presence, but busy themselves with everything rather than with this, and live on, taking no thought but for the passing day and the hardly longer span of their own personal future, either expressly discarding the problem or else over-ready to come to terms with it by adopting some system of popular metaphysics and letting it satisfy them; when, I say, one takes all this to heart, one may come to the opinion that man may be said to be a thinking being only in a very remote sense, and henceforth feel no special surprise at any trait of human thoughtlessness or folly; but know, rather, that the normal man’s intellectual range of vision does indeed extend beyond that of the brute, whose whole existence is, as it were, a continual present, with no consciousness of the past or the future, but not such an immeasurable distance as is generally supposed.”
