Gee Doug,

That argument was months ago. Gues one becomes immortal, or near so,
if one contributes here. Appreciate your agreement. Wish it were
possible to teach the others here that ideas taken from mind rather
than from material data are nought but ideas. All this talk about
number sense without any consideration, as though by magic, of the
material basis for that sense developing on the basis of the actual
work of the brain.

Spelling Doug. Oh mine is generally better than that except I was so
mad I just scribbled and dashed it off. At any rate, as long as it
remains reasonably readable, spelling is not all that important except
as show. Now we have spell checkers (But not on this version of
Eudora) which look for regular words, never mind that sometimes the
regular words mean nothing in the context. Thinking, conscious
thinking based on material data addressed consciously to problems is
what is important.
