These works, as the subtitle makes clear, are unfinished sketches for Philosophical Investigations, among the most important & influential philosophical work of modern times. The 'Blue Book' is a set of notes dictated to Witgenstein's Cambridge students in 1933-34. The 'Brown Book' was a draft for what eventually became the growth of the first part of Philosophical Investigations. This book reveals the germination & growth of the ideas which found their final expression in Witgenstein's later work. It's indispensable therefore to students of Witgenstein's thought & to all those who wish to study at firsthand the mental processes of a thinker who fundamentally changed the course of modern philosophy.

These are lecture notes toward what would later become the PI. They're way less systematic than the big two, but they'll give you a great feel for Wittgenstein's thought.
I'll also second Monk's biography, which is just superb.
One of my favorite things about Wittgenstein, is that there's a powerful strain in his thought that regards philosophical speculation as essentially a form of "madness." That is to say, if you're sitting around wondering what "justice" is or trying to figure out the mind/body distinction, you're engaging in a kind of nonsensical behavior. It is the purpose of philosophy to resolve these problems -- which, in Wittgenstein's case, often meant showing why they're nonsensical questions in the first place -- so you can go back to living your life. In Monk's biography, you often see him revolutionizing modern philosophy and then afterward going to work as a gardener.
I think this explains, in part, why he is more admired than influential in modern analytical philosophy. He is one of the many twentieth-century philosophers to suggest that the proper outcome for philosophy is to stop doing it.

What I was most interested by was how much of this example you could understand. A binkle is some kind of animal, a plackert is some kind of body part, i'd imagine a whipitat is some kind of action, and I'd imagine a snoblat is another kind of body part. Already I know more about binkles than I did.
You're also, however, a long way from a dog simply by describing a 'barking thing'. There are things that bark that are not dogs, and there are somewhere, dogs that do not bark. Wittgenstein demonstrated that there are an entire set of items that you could call a table than share no common features whatsoever.
I'm a fan of the dialectic method for this reason: it encourages people to go beyond the limits of their own knowledge by applying first principles to things they don't understand. This tends to take you a lot further than "here, learn this."

I think it was someone asking if he was familiar with the Wittgenstein Blue and Brown books and of course because he as already an assistant professor at MIT when they came out.
I still chuckle at my own intellectual arrogance and stupidity when thinking about how I was dismissive of Chomsky on language. I barely know anything and I was being dismissive of one of unquestionable titans and historic figures of a field.
