When are we not ourselves?

[Thumpalumpacus]

I think the sense of self is an abstract, emergent property of the human brain.

Ok, what does that have to do with anything?

Uh, the question posed in the thread title? Ring a bell?

"Me" is not defined by cellular composition, in other words. "Me" is amalgam of admittedly imperfect memories ad relationships.

The "me" of now is not the "me" of yesteryear.

Ya think?!

The OP is essentially a recast 747-in-a-junkyard point.

Call it what you want. Call it Abrahams Axe.

You <> point.
