"What embitters the world is not excess of criticism, but the absence of self-criticism"

What embitters the world is not excess of criticism, but the absence of self-criticism. It is comparatively of little consequence that you occasionally break out and abuse other people, so long as you do not absolve yourself. The former is a natural collapse of human weakness; the latter is a blasphemous assumption of divine power.

-Sidelights (1932)
