“Many a man fails to become a thinker only because his memory is too good.”

“Change almost never fails because it's too early. It almost always fails because it's too late.”

“You've got to have as many good times as bad, or it all becomes too painful and too much work.”

“And, as always happens, and happens far too soon, the strange and wonderful becomes a memory and a memory becomes a dream. Tomorrow it's gone.”

“Man lives only to learn. And if he learns it is because it is the nature of his lot, for good or bad.”

“There are too many books I haven’t read, too many places I haven’t seen, too many memories I haven’t kept long enough.”

“When a cartoonist attempts to be ‘fair and balanced’ and ‘understand all sides,’ they have failed. Too many avoid that altogether and instead become comedians. They take any topic and cast about and ask themselves: “What’s funny in this?” I despise that attitude. Sure, satirical humor is an important element, but not the only element. A good cartoonist need not be funny to be effective. Many of my best cartoons are not funny.”

“A great man quotes bravely, and will not draw on his invention when his memory serves him with a word just as good.”

“Many people wish to be placed in the heaven of scientists. Because few thinkers can be found in religion.”

“A man, to be greatly good, must imagine intensely and comprehensively; he must put himself in the place of another and many others; the pains and pleasures of his species must become his own. The great instrument of moral good is the imagination.”
