A man is not learned until he can read, write and swim.
Writing is the geometry of the soul.
Every serious man in dealing with really serious subjects carefully avoids writing. ... There does not exist, nor will there ever exist, any writing of mine dealing with this subject.
He who has knowledge of the just and the good and beautiful ... will not, when in earnest, write them in ink.
. . . Then anyone who leaves behind him a written manual, and likewise anyone who receives it, in the belief that such writing will be clear and certain, must be exceedingly simple-minded. . . .
