"There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance - that principle is contempt prior to investigation.”
I also love quotes by Dorothy Parker. Here's a good 'un:
"She runs the gamut of emotions from A to B."
(speaking of Katharine Hepburn)
Great quotes by a great man, Patton. I like that one by Maya Angelou too...
