"A man's ethical behavior 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."
[Albert Einstein, "Religion and Science", New York Times Magazine, 9
November 1930]
