Good to hear what you say about Jung. Cussen didn't say specifically what his quotes referred to, and even then I assume he was talking only about certain circles within academia. I'm guessing he was referring more to materialistically minded disciplines – sociology? evolutionary biology? Jung is obviously going to part of any transpersonal psychology curriculum anywhere.
It wouldn't be hard to accept Jung's model of the mind, rather than Freud's. His schizophrenia is, of course, very 'alleged'. If you're talking about his 'confrontation with the unconscious', then Jung saw this as the source of all his later creativity. How can that be called madness?
Regarding the archetypes, I would need you to provide references and sources for what you say. Even then, I'm not sure I want to get into a long debate about that. I've already been down that road once before with Mitchell Diamond, and it never really got anywhere. Jung's thinking on the archetypes developed over a long period of time, and it all depends what era you quote from.
