Angels and Demons explores the Functionalist school of thought that one can not know what good is with out experiencing bad, one can not know what law is without unlawfulness. Humans also exist as a result of the equilibrium of positive and negative. Angels and Demons asks the person wearing the garment to introspect ones own personality and character, and figure out what are their positive and negative traits. Ultimately it calls upon persons to rally their positive attributes to once again sustain an equilibrium in the universe.
