Yeah, for the most part I agree. The Tractatus bridges the simplistic but somewhat true 'British Empiricism vs. Continental Rationalism' post-Hegelian divide. In its concerns, it is not limited to a philosophy or logics of empirical science (which to most moderns means experimental science). This I think was the point of confusion in the current discussion.
As for the Tractatus's metaphysics, in that sense it is a self-swallowing, self-repudiating work. It is also an addition to and critique of Russell's (empiricist logical atomism) and Frege's (realist ) conceptualizations of logics. The necessary truths of logic are empty tautologies while metaphysical utterances are nonsense.
Gosh, this stuff is more interesting than TEFL.
