Some good quotes on this thread - can't remember where I read it but apparently
"It's nice to be important but more important to be nice"
Also like these two
"There is a principle which is a bar against all information, which cannot fail to keep a man in everlasting ignorance-- that principle is contempt prior to investigation."
Herbert Spencer, British philosopher
"Sit down before facts like a child, and be prepared to give up every preconceived notion, follow humbly wherever and to whatever abysses Nature leads, or you shall learn nothing."
T.H. Huxley
