I used to think the idea that some people actively disliked speaking about archetypal reality was a reflection of indifference. LSD-heads always told me that there was this conspiracy among conservative types, to suppress it, because it threatens the world order. It was, so they said, as if conservatives saw it as a demon spirit, that would destroy reality if it were let out.
I now agree with them, but I came to this conclusion through an indirect, backdoor way.
I think, when you get that dismissive reaction from someone, the reason is that their subconscious already knows all this, and doesn't find it to be new information. Furthermore, it knows that if it allows this information to be considered by the Ego, it might dissolve its ability to be conscious at all.
Maybe. The subconscious isn't that perfectly personified, but I think that lots of this stuff seems almost agressively uninteresting, even to the point of calling it stupid, reeks of something more.
When I was first introduced to Jung, years ago, I was the same way. I thought, at the time, that I was responding to him trying to fit too many things into his idea of archetype. I think, now, that I felt from my anima a sense of dread, that bad things would happen if I looked at those places when I wasn't ready. I would see a pit of maggots where I should be seeing the recylement of nutrients. It threatened certain structures, things that had become a little enamoured with. I didn't want someone else claiming them for their own pre-existing category. It seemed like Jung (Actually Campbell, who a friend of mine, a hack, wouldn't shut up about) just cast a broad net and sought to take credit for everything motive or creative.
I now think that, far from being vague and general, the archetypes are actually very precise. A great improvement over just processing memory and impressions... The same way that "Metal" might seem vague and general when speaking of substances, but becomes sharply clear when talking about the structure of an atom that gives rise to different alloys' unique properties.
