What a wee little part of a person’s life are his acts and his words!
His real life is led in his head, and is known to none but himself.
All day long, the mill of the brain is grinding, and his thoughts, not those other things, are his history.
— Mark Twain (Autobiography of Mark Twain, Volume 1)
The man who does not read good books has no advantage over the man who can’t read them (via political prof).
