[As an aside, I would like to point out how An Archaeology of the Fall complements Schoonenberg’s classic note on Original Sin.
A transition from hand-speech talk to speech-alone talk potentiated unconstrained complexity.
The intuitive reference of hand-speech talk was replaced by the projected reference of speech-alone talk.
Hand speech talk was an indexal and iconic way of talking. Social specialization was constrained to ‘what could be pointed to or imaged’.
In contrast, speech alone talk, a purely symbolic way of talking, holds no constraints.]
