Having a little trouble following, never-the-less:
The guys who feel they have proven mental universe and that matter is just perception of matter, sort of did rule out "separate" beings I guess.
Never used the word epiphenomenon before, had to look it up. Might be useful. I never have decided what I think about "soul". Doesn't seem useful for a materialist or a mentalist, only a dualist.
Using your word: logic, ethics, and aesthetics might be epiphenomenon of one mind. Hmmm...
Epiphenomenon is a word commonly used by academic materialists to relegate the mind to a situation
of being a causally worthless article. Essentially it lies at the bottom of materialist brainwashing.
Typically one's mind is constructed as having no active agency this way:
Your 'mind' is just caused by atoms which 'control' your thinking -
you have no free will, thus you are now under the control of forces
such as markets or sexual drives. In this way morality is also said to be an illusion,
and therefore you are now the unwitting pawn of others.
This type of thinking, I reckon is what drives most of mob mentality,
whether it is expressed academically, or just implied.
The very possibility of ideas such as 'jou-jou' go a long way to help
breaking down this type of self-inflicted helplessness.
