Context: In 1942 I was the star in one of the filthiest dramas of all time. I was a seaman, and went to the Imperial Café on Scollay Square in Boston to drink; I drank sixty glasses of beer and retired to the toilet, where I wrapped myself around the toilet bowl and went to sleep. During the night at least a hundred seamen and assorted civilians came in and cast their sentient debouchements on me till I was unrecognizably caked. What difference does it make after all? — anonymity in the world of men is better than fame in heaven, for what's heaven? what's earth? All in the mind.

Context: When I speak of reason or rationalism, all I mean is the conviction that we can learn through criticism of our mistakes and errors, especially through criticism by others, and eventually also through self-criticism. A rationalist is simply someone for whom it is more important to learn than to be proved right; someone who is willing to learn from others — not by simply taking over another's opinions, but by gladly allowing others to criticize his ideas and by gladly criticizing the ideas of others. The emphasis here is on the idea of criticism or, to be more precise, critical discussion. The genuine rationalist does not think that he or anyone else is in possession of the truth; nor does he think that mere criticism as such helps us achieve new ideas. But he does think that, in the sphere of ideas, only critical discussion can help us sort the wheat from the chaff. He is well aware that acceptance or rejection of an idea is never a purely rational matter; but he thinks that only critical discussion can give us the maturity to see an idea from more and more sides and to make a correct judgement of it.
