The Soul Contains All the Mankind
We consist of everything the world consists of, each of us, and just as our body contains the genealogical table of evolution as far back as the fish and even much further, so we bear everything in our soul that once was alive in the soul of men. Every god and devil that ever existed, be it among the Greeks, Chinese, or Zulus, are within us, exist as latent possibilities, as wishes, as alternatives. If the human race were to vanish from the face of the earth save for one halfway talented child that had received no education, this child would rediscover the entire course of evolution, it would be capable of producing everything once more, gods and demons, paradises, commandments, the Old and New Testament.
Hermann Hesse, in 'Demian'
