A man is himself important precisely in proportion that all things see — Otto Weininger

"The great genius does not let his work be determined by the concrete finite conditions that surround him, whilst it is from these that the work of the statesman takes its direction and its termination. … It is the genius in reality and not the other who is the creator of history, for it is only the genius who is outside and unconditioned by history."

"Man must act in such a way that the whole of his individuality lies in each moment."

"Psychologism is the most comfortable conception of life, because according to it there are no longer any more problems. That is why it also condemns all solutions from the outset, since it acknowledges the actual problems as little as the idea of truth."

"People should also not want to determine themselves causally in such a way: I will now … become good once and for all, and do good by nature, because I could not then do anything else. For through this one denies the freedom which can in each moment negate all the past. … One makes himself into an object when one establishes causality in that way; for a morality to which I have been compelled is already not a morality."

"Great men take themselves and the world too seriously to become what is called merely intellectual. Men who are merely intellectual are insincere; they are people who have never really been deeply engrossed by things and who do not feel an overpowering desire for production. All that they care about is that their work should glitter and sparkle like a well-cut stone, not that it should illuminate anything. They are more occupied with what will be said of what they think than by the thoughts themselves."

"Idiocy: crudeness’ intellectual equivalent."
