Many a man fails to become a thinker only because his memory is too good. - Friedrich Nietzsche

We have to be careful that in throwing out the devil, we don't throw out the best part of ourselves.

We have to cease to think, if we refuse to do it in the prison house of language; for we cannot reach further than the doubt which asks whether the limit we see is really a limit.

What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding. Truths are illusions which we have forgotten are illusions — they are metaphors that have become worn out and have been drained of sensuous force, coins which have lost their embossing and are now considered as metal and no longer as coins.
