"To die proudly when it is no longer possible to live proudly. Death freely chosen, death at the right time, brightly and cheerfully accomplished amid children and witnesses: then a real farewell is still possible, as the one who is taking leave is still there; also a real estimate of what one has achieved and what one has wished, drawing the sum of one's life — all in opposition to the wretched and revolting comedy that Christianity has made of the hour of death. One should never forget that Christianity has exploited the weakness of the dying for a rape of the conscience; and the manner of death itself, for value judgments about man and the past.
Here it is important to defy all the cowardices of prejudice and to establish, above all, the real, that is, the physiological, appreciation of so-called natural death — which is in the end also "unnatural," a kind of suicide. One never perishes through anybody but oneself. But usually it is death under the most contemptible conditions, an unfree death, death not at the right time, a coward's death. From love of life, one should desire a different death: free, conscious, without accident, without ambush.
Finally, some advice for our dear pessimists and other decadents. It is not in our hands to prevent our birth; but we can correct this mistake — for in some cases it is a mistake. When one does away with oneself, one does the most estimable thing possible: one almost earns the right to live. Society — what am I saying? — life itself derives more advantage from this than from any "life" of renunciation, anemia, and other virtues: one has liberated the others from one's sight; one has liberated life from an objection. Pessimism, pur, vert, is proved only by the self-refutation of our dear pessimists: one must advance a step further in its logic and not only negate life with "will and representation," as Schopenhauer did — one must first of all negate Schopenhauer"
