John - sorry about the line length, I will try to be shorter in 
future. Just a quick couple of comments. 

I see why, given your views on the difference between pure and 
applied mathematics, you would object to my saying that model 
theory can refer to relations between symbols and the world. But 
I do not share those views, as I have now explained carefully 
twice. So please don't go through them again like a patient teacher. 
This recalcitrant student understands you perfectly, but doesn't 
agree with you. If you would like to argue about them, I am quite 
willing to do so, but only if you are willing to take part 
in a philosophical debate rather than simply assume your views are 
correct and explain them again and again.

One little point, however, from your message:

>And when we are trying to implement our theories in a robot, which
>has no built-in commonsense, we have to extremely careful about
>making distinctions between the lexical object types that are
>representable inside the computer and the nonlexical things that

Oh, I entirely agree, and would add all the nonlexical things 
that can't be recognised by any 'pattern recognition techniques' 
[curious anachorism!] such as ideas, forces, countries, 
integers, political agendas, etc. etc.. 

Did you mean, by your didactic tone in stating this platitude, 
to imply that my views somehow lead to a confusion of such 
distinctions? On the contrary, I find your insistence that 
lexical representations must refer only via a computational 
'simalcrum' of something real, which itself is only related 
vaguely to the actual world, to be alarmingly confusing on 
precisely this issue. Your casual way with quotation 
might well be a symptom of this.

PS did you find the 'summary' accurate, by the way? I tried to
give an honest account of what I thought your positions were.
