A man's ethical behavior should be based effectually on sympathy,
education, and social ties; 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
The further the spiritual evolution of mankind advance he more certain it
seems to me that the path to genuine religiosity does not lie through the
fear of life, and the fear of death, and blind faith, but through striving
after rational knowledge....
