Reddit reviews Representation and Reality in Wittgenstein's Tractatus

I'll only add this: the early Wittgenstein (by which I mean first and foremost the author of the Tractatus) formulated an intricate and at times obscure theory about how mind and language represent reality. His theory is impossible to understand just from primary sources; you need to rely on interpreters to decrypt the Tractatus, if only to get a sense of whose ideas Wittgenstein's railing against.

But therein lies the rub. Nowadays we know that most of what Wittgenstein wrote during this period were attempts to mend what he saw as failings of Bertrand Russell's theory of judgement (as it was formulated in one of the manuscripts he happened to have access to). The thing is, Russell's manuscript was only posthumously published in 1984. Hence, most of the pre-1984 exegeses of the Tractatus are highly speculative and not really useful. I'd personally recommend this book as an introduction to Russell's manuscript, and this book as an introduction to the Tractatus.
