My Favorite Pascal Quotation
Blaise Pascal, Pensees #98 (Krailsheimer tr. p. 55):
How is it that a lame man does not annoy us while a lame mind does? Because a lame man recognizes that we are walking straight, while a lame mind says that it is we who are limping.
Please forgive the following reformulation. Point out to a man that he is crippled, and he won't contradict you, though he might take umbrage at your churlishness. But point out to a man that his thinking is crippled and he is sure to repy,"No! It is your thinking that is crippled."
