Excellent chapter! I do, however, think we can look to Kenny and Kohlberg and their ideas on conventionality with its pre and post positions or worldviews (as they relate to morality). Still evolutionary, but structurally real and observable.
And, thanks, you were almost sounding like A Gnostic for a moment there in your descriptions of the brutality​ of the universe and existence:D
I know, I know...
