Ludwig Wittgenstein actually produced TWO CONFLICTING PHILOSOPHIES OF LANGUAGE:
The first is based on Bertrand Russell's ideas about turning language into a set of clear logical relationships, which he criticizes and expands. But the second is a total rejection of the idea that language is "logical" at all! Instead, Philosophical Investigations compares language a kind of game that we play, in a particular context, with other people, to accomplish a particular goal.
I'd like you to watch this video about the dual theories, and then post your observations in the comments. You can tell me which theory you think is "better," and why, or you can compare and contrast them, explain why you think his views changed, etc. But remember, Wittgenstein famously tells us we should keep silent if we have nothing important to say. So think of something good!
