That's exactly what I mean about proposing a notion that serves as a challenge to a point of view. I was pretty confident I was putting forward a statement that someone would take issue with, even if it's part of a sentiment I buy into.

In terms of qualifying one's semblance of self, I think infant amnesia also represents a significant developmental boundary, for "counting" as a self aware human. If you don't remember learning to walk, was it "you" that learned? It's a pretty fluid and blurry line for human existence.
