For several terms at Cambridge in 1939, Ludwig Wittgenstein lectured
on the philosophical foundations of mathematics. A lecture class
taught by Wittgenstein, however, hardly resembled a lecture. 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.
