Based on Jungian Symbolic Psychology, this book attributes an archetypal foundation to the ego defense mechanisms of psychoanalysis and describes the possibility of all psychological functions being creative or defensive. Analysing Peter Shaffers play Amadeus, Byington describes envy functioning creatively and defensively in the Mozart-Salieri relationship. He goes on to demonstrate how psychoanalysis followed Genesis and the Christian doctrine of original sin, scientifically stigmatising envy.
