The rational man will regard his own undesirable acts as he regards those of others, as acts produced by certain circumstances, and to be avoided either by a fuller realisation that they are undesirable, or, where this is possible, by avoidance of the circumstances that caused them.
As a matter of fact the sense of sin, so far from being a cause of s good life, is quite the reverse.

Context

“But even when a man has offended against his own rational code, I doubt whether a sense of sin is the ‘best method of arriving at a better way of life. There is in the sense of sin something abject, something lacking in self-respect. No good was ever done to anyone by the loss of self-respect. The rational man will regard his own undesirable acts as he regards those of others, as acts produced by certain circumstances, and to be avoided either by a fuller realisation that they are undesirable, or, where this is possible, by avoidance of the circumstances that caused them. 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.” source
