It took several minutes of Googling to find a plausible expansion of CTM, 
at http://plato.stanford.edu/entries/computational-mind/ . I guess 
objectively that's hardly any work at all compared to what would have been 
needed in the past, but in the modern world it feels like that makes "CTM" 
incredibly cryptic. :D

But all the forms of language do share a common logical basis, according to 
many linguists.  How is it relevant to the logic of a language that it can 
be expressed in different modalities?

"local to aesthetic textures ..." -- would you mind recasting the sentence 
into more concrete terms?  I haven't the foggiest idea what you're trying 
to communicate.

That appears untrue.  I know birds, mammals, some molluscs, and some fish 
can reason abstractly about motor behaviors and achieve the same goal with 
very different kinds of motor behaviors.
