Have to disagree with Jonathan on two points:
1) No, he's not getting dumber (that was just a Borgesian take-off on Ron Padgett): he's getting smarter & more scintillant as he blogs along.
2) No, my comments do not provide an example of Heriberto's point. One person's "ideological projection" is another person's empirical observation. Sure, there's continuity between the child you & me & the adult you & me; but there's a difference too. As Jordan pointed out, the difference is dependence (economic, social, psychological). It's a relationship which changes the terms of its balance as the child becomes the independent adult (& perhaps a parent in turn).
If I view this through a theological kaleidoscope, this does not mean its basis in empirical reality is cancelled out. The child/parent relation is there : it's not an ideological projection (though my theological corollary, on the other hand, might be).
Heriberto saying there's no such thing as childhood strikes me as a kind of sophism (nominalism?).
