A New Essay linking linguistics and metaphysics and logic

Here is the abstract for a new essay I’ve completed:

“Some say that the distinction between nouns and verbs is present in every human language.  Some even say that such a distinction must be in every human language.  Others give analyses to show that a particular language does not have a noun-verb distinction.  By reviewing this controversy we will see how issues of language universals, metaphysics, relativity in language and thought, and methodology of investigation in linguistics are intertwined.”

I’d be very glad to get comments and criticism.
