" The survival instinct, however, is self-conscious in human beings; and when it consciously motivates our behavior, it defines us as radically self-centered creatures. Our self-centered drive to survive is a universal reality rooted in our biology. It was this aspect of our humanity that led our ancient religious mythmakers to try to describe its origins. “Original sin” was their answer to the question of the source of our universal human self-centeredness. No one understood that survival was an involuntary biological drive in life. Instead it was understood as the result of sinfulness and of disobedience. Atonement theology was born as a way to address this universal flaw in our understanding of human life. "
