Wondering vaguely if children -- and subsequently adults -- are inherently selfish. And, based on the need to survive, I guess they probably are. But the question that arises after having survived is, who survives? What self is it, precisely, about which anyone might be -ish?
The -ish suffix implies approximation. Blue-ish, tall-ish, sweet-ish. Is there an approximate self ... or an exact one either? If we are imitating something called the self -- stage-managing some play called "I, Myself and Me" -- then who is doing the imitation?
This is a point at which Buddhism can be useful. Check it out. It's interesting-ish.
