Evolution is not finished; reason is not the last word nor the reasoning animal the supreme figure of Nature. As man emerged out of the animal, so out of man the superman emerges.
He who can see truly in the midst of general infatuation is like a man whose watch keeps good time, when all clocks in the town in which he lives are wrong. He alone knows the right time; what use is that to him?
I suggest that we are thieves in a way. If I take anything that I do not need for my own immediate use, and keep it, I thieve it from somebody else. ... Nature produces enough for our wants from day to day, and if only every-body took enough for himself and nothing more, there would be no pauperism in this world, there would be no man dying of starvation in this world. But so long as we have got this inequality, so long we are thieving.

Such immaturity is self-caused if it is not caused by lack of intelligence, but by lack of determination and courage to use one's intelligence without being guided by another. Sapere Aude! Have the courage to use your own intelligence! is therefore the motto of the enlightenment.
