Sigmund Freud Quote
In every age immorality has found no less support in religion than morality has. If the achievements of religion in respect to man's happiness, susceptibility to culture and moral control are no better than this, the question cannot but arise whether we are not overrating its necessity for mankind, and whether we do wisely in basing our cultural demands upon it.
