There's a certain quantity of text to read, but I'd be curious to have some opinions.
The whole "higher level" thing kind of bugged me at first, so I'd just advise to take the whole idea as a picture, just like you couldn't reach the 3rd floor of a building without going through the second, not meaning that the 3rd floor is actually "better" than the 1st.

Well yep, that's a bit of tl;dr but I've actually managed to read that :>

I don't know crap about psychology, but it looks like a praise of a (gradual) progression form a primal, animalistic and egoistic point of view to the ol' good enlightement and empathy. Dunno where's anything out of ordinary here, these virtues were probably always praised (or at least since rennaisance or something) - sensitivity and personality over primitive selfishness and groupthink and all that jazz. Personality carved by destructive processes sounds familiar too. Either that guy was trying to find new words for common stuff or I just need to read all of this again, carefully.
