Thomas Huxley

Science ... warns me to be careful how I adopt a view which jumps with my preconceptions, and to require stronger evidence for such belief than for one to which I was previously hostile. My business is to teach my aspirations to conform themselves to fact, not to try and make facts harmonize with my aspirations.

Thoughtfulness for others, generosity, modesty, and self-respect are the qualities which make a real gentleman or lady.
