Whoa nelly! He's really not kidding around when he uses a word like "investigations." There's an abundance of dialogue here that is centered around proving the intangible nature of meaning in language and the effect (though I envision it as a kind of grip) that said language has on our mental states. My absolute favorite parts are those regarding the question of whether there is such a thing as a private language. I also appreciate the general attitude that any philosophical problem bugs you because you're using the wrong words anyway, and that's the root of it all. It's excellent in the way that it causes frustration (perhaps due to the translation - every philosophical work translated from German always seems incredibly and unnecessarily dense to me, but that could just be my perception). However, it's a healthy and activity-heavy philosophical read that really makes you think and engage with the ideas presented.
