Selfishness, he wrote in Escape from Freedom, is a kind of greediness. But like other forms of greed it is never satisfied, it is insatiable. The selfish person never gets enough attention, or praise. There is always a fear of not having enough, of being deprived of something. And so there is always an envy of anyone who might have 'more'.
Narcissism is an inordinate love of self, which is at root a form of self-hatred.
We are creatures both of light and of darkness. We are like God, and like the devil. We are glorious, and we are sinful. We are lovable, and our evil thoughts words and deeds are a horror to God. Lord, save me from selfishness, which is a greedy preoccupation with myself.
