...Our job as educators is to lead our students by unmasking the equivocal nature underlying conventional wisdom and the status quo. We will never succeed if we don't tell them that we're pretending; that we're just wearing a mask, playing the role of a teacher, in the same way we demand that they play the part of a student...
While your quote is well written, thoughtful, and generally true in a philosophical kind of way, its not very helpful 
Also, insofar as language teaching goes, I would disagree about conventional wisdom being equivocal. A verb is a verb, and a noun is a noun (unless it's a gerund, or part of a adverb clause, or...)
Also, I can barely convey to my students how I feel about them sleeping in class, so I seriously doubt that I'll be trying to communicate to them any time soon how I really am a human being just like them (even if I do speak a funny language, have funny coloured hair, and wear t-shirts with grunge-era band logos printed on them).
I was thinking in idealistic terms. I like to think that teaching can be transformative. That's not part of the job description: we're not required to go beyond the literal conception of language. In many ways, students have a hard enough time with that. It therefore seems that, from an everyday standpoint, it is rather absurd to even attempt to communicate something complex and thought provoking to unmotivated students.
On the other hand, we have to challenge ourselves and our students to learn something different. You can point out that a verb is just verb, and yet more often than not, a verb can be used as an adjective or a noun. And that's just the mechanics of the language when parsed out in terms of grammatical function. We haven't even discussed the possibilities of significance and meaning revealed (but not limited) to complex forms of speech and writing such as stories and poems.
If we settle for the easy way out,, then we have less of a right to demand our students to listen to us.
