The aim of science is to apprehend this purely intelligible world as a thing in itself, an object which is what it is independently of all thinking, and thus antithetical to the sensible world.... The world of thought is the universal, the timeless and spaceless, the absolutely necessary, whereas the world of sense is the contingent, the changing and moving appearance which somehow indicates or symbolizes it.

The value of history. ..is that it teaches us what man has done and thus what man is.

What a man is ashamed of is always at bottom himself; and he is ashamed of himself at bottom always for being afraid.

A man ceases to be a beginner in any given science and becomes a master in that science when he has learned that... he is going to be a beginner all his life.

Every new generation must rewrite history in its own way.
