Surely an interesting take on metaphysics and epistemology, with an interesting method of exposition surrounding it.
Not the most enjoyable philosophy book you will read in your life, but surely a very important one the theory of which still reverberate in language theory, and even in spirituality, nowadays.

A friend told me that someone bringing Wittgenstein up in a conversation was the very definition of pretentiousness. So I'm pretentious. Live with it. Even though part of the reason that I read this was to impress my friends, I also hoped to gain something from it. Wittgenstein, after all, is an interesting character. In the end, I'm not sure that I gained much from the book---I don't feel bad about this, since Wittgenstein told the philosophers of his day who had embraced the book that they totally missed the point---other than this one interesting way of looking at the Universe: the Universe does not consist of things. It's not made of a bunch of objects. What the universe is, is a bunch of facts. The Universe is composed of truths. The things are there, but more fundamental than the things are the truths. Things can't exist at all, without facts. I'm not sure whether this point of view is right or wrong (or neither), but it is an interesting way of looking at things.

"Mathematics is a method of logic."

I had trouble understanding his references involving Frege and Russell, because I haven't read them yet. Even so, I think I followed the gist of his ideas. Interesting points about solipsism.

At first I thought I could use observations from this book to write some interesting inferencing software, but then Wittgenstein went the other direction and said that I couldn't describe logical rules like that... I have a feeling Frege and Russell will set me free, despite his criticism of Frege's "Theory of meaning of propositions and functions."

Fascinating. Can't say I understood much, if anything at all. Merits more than one re read

"Wir fühlen, daß selbst, wenn alle möglichen wissenschaftlichen Fragen beantwortet sind, unsere Lebensprobleme noch gar nicht berührt sind. Freilich bleibt dann eben keine Frage mehr; und eben dies ist die Antwort" (6.52)

Will read again when I have learned enough or I have succumbed to madness

Mind boggling book with a beautiful ending. Background in symbolic logic will help but not absolutely necessary to appreciate in it’s entirety.
