> Other oddities " Richmond Thomason notes that Montague saw grammar as a branch of mathematics and not (as in Chomsky) of psychology". Pretty sure Chomsky's hierarchy of grammars, types 3 to 0, are considered by him as mathematical, not psychological. I would suggest looking up Chomsky and mentalism. This is a core feature of his theory. Early in his career Chomsky did have interesting things to say about formal language theory and you're right that Chomsky would not consider regular languages or the grammar of Python, for instance, to be psychological but this isn't the grammar that the author is concerned with here.
