"I do nothing but go about persuading you all, old and young alike, not to take thought for your persons or your properties, but and chiefly to care about the greatest improvement of the soul. I tell you that virtue is not given by money, but that from virtue comes money and every other good of man, public as well as private. This is my teaching, and if this is the doctrine which corrupts the youth, I am a mischievous person." - Socrates.
"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." - Einstein
"It is because modern education is so seldom inspired by a great hope that it so seldom achieves great results. The wish to preserve the past rather that the hope of creating the future dominates the minds of those who control the teaching of the young." - Russell
