I know of one gifted crackpot who used to be employed gainfully in the fields of humor and satire, who has taken a solemn pledge not to write anything funny or lighthearted or “insignificant” again till things get straightened around in the world. This seems to me distinctly deleterious and a little silly. A literature composed of nothing but liberty-loving thoughts is little better than the propaganda which it seeks to defeat.
