He sat on a chair in the middle of the room, with some of the class sitting in chairs, some on the floor. He never used notes. He paused frequently, sometimes for several minutes, while he puzzled out a problem. He often asked his listeners questions and reacted to their replies. Many meetings were largely conversation.
These lectures were attended by, among others, D. A. T. Gasking, J. N. Findlay, Stephen Toulmin, Alan Turing, G. H. von Wright, R. G. Bosanquet, Norman Malcolm, Rush Rhees, and Yorick Smythies. Notes taken by these last four are the basis for the thirty-one lectures in this book.
The lectures covered such topics as the nature of mathematics, the distinctions between mathematical and everyday languages, the truth of mathematical propositions, consistency and contradiction in formal systems, the logicism of Frege and Russell, Platonism, identity, negation, and necessary truth. The mathematical examples used are nearly always elementary.

This set of 31 lectures is very well compiled and illustrates Wittgenstein's post-Tractatus views brilliantly. In fact, I think this text makes understanding Wittgenstein's 'Philosophical Investigations' even easier than the Blue and Brown books. Of particular interest in this text is the dialogue between Wittgenstein and Alan Turing(of WWII Enigma code fame and considered to be the father of modern computing).
