“Wit and humor do not reside in slow minds.”
“Humor is the only test of gravity, and gravity of humor; for a subject which will not bear raillery is suspicious, and a jest which will not bear serious examination is false wit.”
“Are you slow-witted? I'm so sorry for you. It's terrible to be dull and stupid.”
“To my mind, a well-developed sense of humor is the surest indication of a person's humanity, no matter how black and bitter that humor may be.”
“No mind is thoroughly well-organized that is deficient in a sense of humor.”
“Faith and doubt cannot reside in the same mind at the same time, for one would dispel the other.”
