It is easier to be critical than correct.

There are three kinds of lies: lies, damned lies, and statistics.

Man is not the creature of circumstances, circumstances are the creatures of men. We are free agents, and man is more powerful than matter.

Bore: one who has the power of speech but not the capacity for conversation.
