Life and writing

Friedrich Nietzsche lived from 1844 to 1900. He taught classical philology at Basel before leaving his professorship in 1879. His philosophical writing developed through criticism of inherited assumptions about culture, morality and religion, often examining the motives behind judgments that appear self-evident.

Human, All-Too-Human appeared in 1878 and marked a turn toward short numbered passages. A complete aphorism may make an argument, stage an objection or expose a tension rather than settle a question. The archive preserves whole numbered units in historical English translations; neighbouring passages and the larger work help readers assess the claim being made.

Reading this voice

Begin with a complete numbered passage, then follow the source reference into the same edition linked below. Helen Zimmern’s 1909 Part I and Paul V. Cohn’s 1913 Part II have different translation choices. Do not treat a historical argument as a fact merely because it is memorable. Some passages contain dated social assumptions. The approximate 1872 timeline coordinate is the midpoint of 1844–1900, not the composition date of the words.

Quotations and sayings

01c. 1872 AD
The Philosophy that Society always Needs.—The pillars of the social structure rest upon the fundamental fact that every one cheerfully contemplates all that he is, does, and attempts, his sickness or health, his poverty or affluence, his honour or insignificance, and says to himself, “After all, I would not change places with any one!”—Whoever wishes to add a stone to the social structure should always try to implant in mankind this cheerful philosophy of contentment and refusal to change places.

Standard for the Value of Truth.—The difficulty of climbing mountains is no gauge of their height. Yet in the case of science it is different!—we are told by certain persons who wish to be considered “the initiated,”—the difficulty in finding truth is to determine the value of truth! This insane morality originates in the idea that “truths” are really nothing more than gymnastic appliances, with which we have to exercise ourselves until we are thoroughly tired. It is a morality for the athletes and gymnasts of the intellect.

In the Night.—So soon as night begins to fall our sensations concerning everyday matters are altered. There is the wind, prowling as if on forbidden paths, whispering as if in search of something, fretting because he cannot find it. There is the lamplight, with its dim red glow, its weary look, unwillingly fighting against night, a sullen slave to wakeful man. There are the breathings of the sleeper, with their terrible rhythm, to which an ever-recurring care seems to blow the trumpet-melody—we do not hear it, but when the sleeper's bosom heaves we feel our heart-strings tighten; and when the breath sinks and almost dies away into a deathly stillness, we say to ourselves, “Rest awhile, poor troubled spirit!” All living creatures bear so great a burden that we wish them an eternal rest; night invites to death.—If human beings were deprived of the sun and resisted night by means of moonlight and oil-lamps, what a philosophy would cast its veil over them! We already see only too plainly how a shadow is thrown over the spiritual and intellectual nature of man by that moiety of darkness and sunlessness that envelops life.

Absence of Feeling of New Chains.—So long as we do not feel that we are in some way dependent, we consider ourselves independent—a false conclusion that shows how proud man is, how eager for dominion. For he hereby assumes that he would always be sure to observe and recognise dependence so soon as he suffered it, the preliminary hypothesis being that he generally lives in independence, and that, should he lose that independence for once in a way, he would immediately detect a contrary sensation.—Suppose, however, the reverse to be true—that he is always living in a complex state of dependence, but thinks himself free where, through long habit, he no longer feels the weight of the chain? He only suffers from new chains, and “free will” really means nothing more than an absence of feeling of new chains.

The Fundamental Errors.—A man cannot feel any psychical pleasure or pain unless he is swayed by one of two illusions. Either he believes in the identity of certain facts, certain sensations, and in that case finds spiritual pleasure and pain in comparing present with past conditions and in noting their similarity or difference (as is invariably the case with recollection); or he believes in the freedom of the will, perhaps when he reflects, “I ought not to have done this,” “This might have turned out differently,” and from these reflections likewise he derives pleasure and pain. Without the errors that are rife in every psychical pain and pleasure, humanity would never have developed. For the root idea of humanity is that man is free in a world of bondage—man, the eternal wonder-worker, whether his deeds be good or evil—man, the amazing exception, the super-beast, the quasi-God, the mind of creation, the indispensable, the key-word to the cosmic riddle, the mighty lord of nature and despiser of nature, the creature that calls its history “the history of the world”! Vanitas vanitatum homo.

Immoralists.—Moralists must now put up with being rated as immoralists, because they dissect morals. He, however, who would dissect must kill, but only in order that we may know more, judge better, live better, not in order that all the world may dissect. Unfortunately, men still think that every moralist in his every action must be a pattern for others to imitate. They confound him with the preacher of morality. The older moralists did not dissect enough and preached too often, whence that confusion and the unpleasant consequences for our latter-day moralists are derived.

A Caution against Confusion.—There are moralists who treat the strong, noble, self-denying attitude of such beings as the heroes of Plutarch, or the pure, enlightened, warmth-giving state of soul peculiar to truly good men and women, as difficult scientific problems. They investigate the origin of such phenomena, indicating the complex element in the apparent simplicity, and directing their gaze to the tangled skein of motives, the delicate web of conceptual illusions, and the sentiments of individuals or of groups, that are a legacy of ancient days gradually increased. Such moralists are very different from those with whom they are most commonly confounded, from those petty minds that do not believe at all in these modes of thought and states of soul, and imagine their own poverty to be hidden somewhere behind the glamour of greatness and purity. The moralists say, “Here are problems,” and these pitiable creatures say, “Here are impostors and deceptions.” Thus the latter deny the existence of the very things which the former are at pains to explain.
