[comp.ai] Infinity

engelson-sean@CS.YALE.EDU (Sean Philip Engelson) (11/18/88)

I think that one important distinction that should have been, but was
not, made is that the size of infinity has nothing to do with the size
of the _concept_ `infinity'.  We could, of course, debate what exactly
`concept' or `meaning' means, but begging that question, we can easily
represent the concept `skyscraper' in less space than a skyscraper
actually takes up, viz. in our heads.  And if you want to maintain
that concepts are non-physical (and thus are not `in our heads' at
all), then you must also say that their `sizes' (whatever that may
mean) have no commensurability with the sizes of physical objects.
Thus the fact that a physical infinity is `really, really big' has no
bearing on the possibility of finite representation of the concept of
infinity.

The frame problem and the problem of formalizing our intuiutions about
inductive relevance are, in every important respect, the same thing.
It is just as well, perhaps, that people working on the frame problem
in AI are unaware that this is so.  One imagines the expression of
horror that flickers across their CRT-illuminated faces as the awful
facts sink in.  What could they do but "down-tool" and become
philosophers?  One feels for them.  Just think of the cut in pay!
