"In our youthful years we respect and despise without that art of nuance which constitutes the best thing we gain from life, and, as is only fair, we have to pay dearly for having assailed men, and things which Yes and No in such a fashion. Everything is so regulated that the worst of all tastes, the taste for the unconditional, is cruelly misused and made a fool of until a man learns to introduce a little art into his feelings and even to venture trying the artificial: as genuine artists do. The anger and reverence characteristic of youth seem to allow themselves no peace until they have falsified men and things in such a way that they can vent themselves on them --- youth as such is something that falsifies and deceives. 

"Later, when the youthful soul, tormented by disappointments, finally turns suspiciously on itself, still hot and savage even in its suspicion and pangs of conscience: how angry it is with itself now, how it impatiently rends itself, how it takes revenge for its long self-delusion, as if it had blinded itself deliberately! During this transition one punishes oneself by distrusting one's feelings; one tortures one's enthusiasm with doubts, indeed one feels that even a good conscience is a danger, as though a good conscience were a screening of oneself and a sign that one's subtler honesty had grown weary; and above all one takes sides, takes sides on principle, against 'youth'.

 --- A decade later: and one grasps that all this too --- was still youth! "

Friedrich Nietszche, Beyond Good and Evil
