"My propositions are elucidatory in this way: he who understands me finally recognizes them as senseless, when he has climbed out through them, on them, over them. (He must so to speak throw away the ladder, after he has climbed up on it.) He must transcend these propositions, and then he will see the world aright."

I think that's kinda the whole point of the Tractatus: much of philosophy (metaphysics and ethics, particularly) has no sense. Strictly speaking, they mean nothing.

Wittgenstein's early work inspired the development of modern analytic philosophy both in its use of formal methods and its claim that much of what was then considered philosophy was meaningless. The decades immediately following Wittgenstein were concerned with linguistic analysis (what the authors of these papers take fault with), while more contemporary philosophy has conceded to a kind of naturalism, appealing to the sciences.

If you place any value on modern analytic philosopher (even as a Popperian), you have to at least give Wittgenstein some historical credit even if the philosophical travesties of the logical positivists can be attributed to misinterpretations of the Tractatus.

With regards to decent philosophers with direct influence from Wittgenstein, what's your take on Kripke and Anscombe?
