The Philosopher's Baedeker: Wittgenstein's Tractatus as Guidebook

The Wittgenstein of the Tractatus is committed to four central and interlocking claims: a limit to sense and nonsense can be drawn in logic; a limit to meaningful and meaningless language – to meaningful and meaningless nonsense – cannot be drawn in logic; whether nonsense is meaningful is shown in its use rather than its form; the Tractatus consists largely of meaningful nonsense. Undergirding these commitments is an account of language‐to‐world picturing in which shared “mathematical multiplicities” play a key role. Picturing as a global phenomenon – language‐to‐world, rather than proposition‐to‐fact – has not been well understood. The Tractatus is not a textbook. No doctrines are developed in it. No problems solved. Instead, it is a kind of Baedeker, a guidebook for those who want “to see the world aright.”
