Hehe... well, first of all, it's not necessarily my argument, but
Dijkstra's, or at least my rough approximation thereof. But I tend to agree
with Dijkstra on this one, so I'll let you argue with me anyway. ;)
Speaking as one who experiences memory loss for various reasons, I will
admit that there are certain memories which I can't seem to conjour up, even
though I have "learned" them in the past. However, that doesn't mean they're
gone. Perhaps they just weren't indexed properly. I have yet to learn how to
do a linear scan on my brain (anyone have a code snippet for that?)
Anyway, even if the *memory* is gone, the *effect* of learning is still a
part of us. What we know today is the direct result of a chain of causes and
effects which we'll never be able to retrace.

You might be right, but if I'm still suffering from BASIC when I'm 80, I
think I ought to be able to sue someone. =)
