John Steinbeck discusses the concept of Rejection in his book 'East of Eden' based on the Bible story of Cain and Able.
The greatest terror a child can have is that he is not loved, and rejection is the hell he fears. I think everyone in the world to a large or small extent has felt rejection. And with rejection comes anger, and with anger some kind of crime in revenge for the rejection, and with the crime a guilt — and there is the story of mankind.
I think that if rejection could be amputated, the human would not be what he is. Maybe there would be fewer crazy people. I am sure in myself there would not be many jails. It is all there — the start, the beginning.
One child, refused the love he craves, kicks the cat and hides his secret guilt; and another steals so that money will make him loved; and the third conquers the world — and always the guilt and revenge and more guilt. The human is the only guilty animal.
Now wait! Now i think this old and terrible story is important because it is the chart of the human soul — the secret, rejected, guilty soul.
