The double fight against evil

When misfortune overtakes us we can either pass over it so lightly that its cause is removed, or so that the result which it has on our temperament is altered, through a changing, therefore, of the evil into a good, the utility of which is perhaps not Visible until later on. Religion and art (also metaphysical philosophy) work upon the changing of the temperament, partly through the changing of our judgement on events (for instance, with the help of the phrase " whom the Lord loveth He chasteneth "), partly through the awakening of a pleasure in pain, in emotion generally (whence the tragic art takes its starting-point). The more a man is inclined to twist and arrange meanings the less he will grasp the causes of evil and disperse them; the momentary mitigation and influence of a narcotic, as for example in toothache, suffices him even in more serious sufferings. The more the dominion of creeds and all arts dispense with narcotics, the more strictly men attend to the actual removing of the evil, which is certainly bad for writers of tragedy; for the material for tragedy is growing scarcer because the domain of pitiless, inexorable fate is growing ever narrower, —but worse still for the priests, for they have hitherto lived on the narcotisation of human woes. - Nietzsche, "Human, all too human", fragment n. 108.
