Heaping glowing coals on another person's head is usually misunderstood and comes to nothing because the other person knows just as well that he is in the right and has also given some thought on his own part to heaping coals.
A belief, however necessary it may be for the preservation of a species, has nothing to do with truth. The falseness of a judgment is not for us necessarily an objection to a judgment. The question is to what extent it is life-promoting, life-preserving, species preserving, perhaps even species cultivating. To recognize untruth as a condition of life--that certainly means resisting accustomed value feelings in a dangerous way; and a philosophy that risks this would by that token alone place itself beyond good and evil.
We have no organ at all for knowledge, for truth: we know (or believe or imagine) precisely as much as may be useful in the interest of the human herd, the species: and even what is here called usefulness is in the end only a belief, something imagined and perhaps precisely that most fatal piece of stupidity by which we shall one day perish.
...If I continued to harbour any hope for music it lay in the expectation that a musician might come who was sufficiently bold, subtle, malicious, southerly, superhealthy to confront that music and in an immortal fashion take revenge on it.
We are, indeed, not among the least contented. You, however, if your belief makes you blessed then appear to be blessed! Your faces have always been more injurious to your belief than our objections have! If these glad tidings of your Bible were written on your faces, you would not need to insist so obstinately on the authority of that book ... As things are, however, all your apologies for Christianity have their roots in your lack of Christianity; with your defense plea you inscribe your own bill of indictment.
What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding. Truths are illusions which we have forgotten are illusions — they are metaphors that have become worn out and have been drained of sensuous force.
