Could make little sense of this one.

Most puzzling and thoroughly lost to logic, devilishly daunting yet refreshing and relieving. An uneasy masterpiece. ( )

Really challenging and amazing that he wrote the whole thing while being shot at as a soldier in WW1! ( )

If we accept (what seems to be?) Wittgenstein's conclusion that the ultimate truths of philosophy are inexpressible, ineffable truths which cannot be put into words, then the most any philosophical work can be is a flawed account which nonetheless can, when we reflect upon it (by recognizing the points where it is mistaken, for example), point us in the right direction. While I suppose the writings of every philosopher from Plato to Putnam is capable of doing this, some make the process easier than others, adequately discouraging us from falling into the trap of fundamentalism, of taking what they say (or seem to say) too seriously. Alongside Nietzsche (whom Wittgenstein admired) and Derrida as masters of this technique, the early Wittgenstein has clearly more than earned his place.

The Tractatus is at least as much a poem as it is philosophy, although Wittgenstein clearly would have denied any hard-and-fast distinction between the two types of writing. Wittgenstein moves from theories of language in the first few sections of the book into examinations of mysticism and religion, leading the reader to the understanding that everything Wittgenstein has said or could say about metaphysics must be nonsense, but at the same to a type of spiritual enlightenment, even if the subsequent understanding of the relationship between humans, God, language, and the world cannot be put into words.

Interesting and stark, it showcases the mathematical background of the author quite well. Too bad that later in life, W. himself recanted what he put forth in terms of metaphysics and language via this book.
