The measure of intelligence is the ability to change. - Albert Einstein

"I never made one of my discoveries through the process of rational thinking"

"Wisdom is not a product of schooling but of the lifelong attempt to acquire it."

"The pursuit of truth and beauty is a sphere of activity in which we are permitted to remain children all our lives."

"I believe in intuitions and inspirations...I sometimes FEEL that I am right. I do not KNOW that I am."

"A man's ethical behaviour should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death."
