As a matter of fact the sense of sin, so far from being a cause of s good life, is quite the reverse. It makes a man unhappy and it makes him feel inferior. Being unhappy, he is likely to make claims upon other people which are excessive and which prevent him from enjoying happiness in personal relations. Feeling inferior, he will have a grudge against those who seem superior.
