Eh, metaphysics are a coping mechanism for the lack of scientific knowledge. With the advent of evolutionary psychology, man's soul can be slowly peeled off as to stare into the nothingness that'll be revealed at its core.
I read quite a bit of that school as well. Mostly work by Buss tbh, but I don't agree with it. To explain a bit, from my own experience with life, the substratum of the material "world", whether its material in the psychic sense or in the chemical sense, supersedes the content. Or rather, the one united reality simultaneously becomes both the subject and object of experience. All evolutionary psychology, or any other theory for that matter, does, is creating psychic phenomena to "copy" or "portray" the actual thing. Only these copies are always faulty and inaccurate. You don't need them to explain things. All the explanations are evident, and you don't even need eyes to see them. All it takes is very sharp awareness without distractions.
