Describe symbolism in The Pursuer by Julio Cortazar

Johnny is a symbol of both good and evil..... an angel and a devil.

"Johnny doesn't give a good [g——d——] if everything goes to hell."

"Anyone can be like Johnny if he just resigns himself to being a poor devil."

"..... he played like I imagine only a god can play an alto sax, given that they quit using lyres and flutes."

"..... maybe what is really happening is that Johnny is a man among angels, one reality among the unrealities that are the rest of us."
