James D. McCawley, a polymath who sadly died about 14 years ago, was a strident voice opposing the removal of consideration of meaning from studies of grammar:
“Semantics/logic/pragmatics (it’s impossible to talk in any detail about any of these three fields without getting into the other two, so I don’t even try to keep them separate). I teach courses on logic from a linguist’s point of view, taking a broad view of the subject matter of logic (logic has suffered from 23 centuries of myopia, which I try to make up for) and giving full weight to linguistic considerations in revising (or replacing) existing systems of logic to maximize their contact with natural language syntax and linguistic semantics.” (See my book, Everything that Linguists Have Always Wanted to Know About Logic (but were Ashamed to Ask), University of Chicago Press, 2nd edition, 1993). I also from time to time teach courses in lexical semantics, tense and aspect, and speech acts (with Erving Goffman sharing top billing with J. L. Austin).”

This is the place to post questions and discussions on usage and style. The members of the Wordwizard Clubhouse will also often be able to help you to formulate that difficult letter.
