" The coldest most rational scientific madness is also the most intolerable. But when a man has acquired a certain ability to subsist, even rather scantily, in a certain niche with the help of a few grimaces, he must either keep at it or resign himself to dying the death of a guinea pig. Habits are acquired more quickly than courage, especially the habit of filling one's stomach. "

― Louis-Ferdinand Céline , Journey to the End of the Night
