"The wrathful and reverent attitudes characteristic of youth do not seem to permit themselves any rest until they have forged men and things in such a way that these attitudes may be vented on them--after all, youth in itself has something of forgery and deception. Later, when the young soul, tortured by all kinds of disappointments, finally turns suspiciously against itself, still hot and wild, even in its suspicion and pangs of conscience--how wroth it is with itself now! how it tears itself to pieces, impatiently! how it takes revenge for its long self-delusion, just as if it had been a deliberate blindness! In this transition one punishes oneself with mistrust against one's own feelings; one tortures one's own enthusiasm with doubts; indeed, one experiences even a good conscience as a danger, as if it were a way of wrapping oneself in veils and the exhaustion of subtler honesty--and above all one takes sides, takes sides on principle, against "youth."-- Ten years later one comprehends that all this, too--was still youth."
--Nietzsche, Beyond Good and Evil, Part Two ("The Free Spirit"), 31.
