The deeper, lonelier truth is that the "fragile angel" view doesn't actually pay rent, and you do much better modeling other people as vicious reptilian warminds with transiently self-aware neocortices stapled on as an afterthought.
This doesn't actually seem to be true, at least economically.
Poetic license.
Edit: The cynical Hansonian/Wattsian view is that the neocortex is there to confabulate a rationalization for what the lizard brain decided to do. We cooperate for game theoretic reasons. Then we explain them as being angelic, altruistically driven impulses. Which framing is "true?" Does it matter?
This is the earlier promised post about Dealing with a Major Personal Crisis. Please continue reading there but comment here.
The reasons for posting it this way are explained at the end of the link. I hope this approach does what I want it to.
