Mankind surely does not represent an evolution toward a better or stronger or higher level, as progress is now understood. This "progress" is merely a modern idea, which is to say, a false idea. The European of today, in his essential worth, falls far below the European of the Renaissance; the process of evolution does not necessarily mean elevation, enhancement, strengthening.
True enough, it succeeds in isolated and individual cases in various parts of the earth and under the most widely different cultures, and in these cases a higher type certainly manifests itself; something which, compared to mankind in the mass, appears as a sort of superman. Such happy strokes of high success have always been possible, and will remain possible, perhaps, for all time to come. Even whole races, tribes and nations may occasionally represent such lucky accidents.


Upon this theological instinct I make war: I find the tracks of it everywhere. Whoever has theological blood in his veins is shifty and dishonourable in all things. The pathetic thing that grows out of this condition is called faith: in other words, closing one's eyes upon one's self once for all, to avoid suffering the sight of incurable falsehood. People erect a concept of morality, of virtue, of holiness upon this false view of all things; they ground good conscience upon faulty vision; they argue that no other sort of vision has value any more, once they have made theirs sacrosanct with the names of "God," "salvation" and "eternity." I unearth this theological instinct in all directions: it is the most widespread and the most subterranean form of falsehood to be found on earth. Whatever a theologian regards as true must be false: there you have almost a criterion of truth. His profound instinct of self-preservation stands against truth ever coming into honour in any way, or even getting stated. Wherever the influence of theologians is felt there is a transvaluation of values, and the concepts "true" and "false" are forced to change places: what ever is most damaging to life is there called "true," and whatever exalts it, intensifies it, approves it, justifies it and makes it triumphant is there called "false."... When theologians, working through the "consciences" of princes (or of peoples--), stretch out their hands for power, there is never any doubt as to the fundamental issue: the will to make an end, the nihilistic will exerts that power...
