‘Wittgenstein wrote a great on the foundations of mathematics between 1929 and 1944. During this period, he discussed the philosophical problems of the foundations in several sets of lectures at Cambridge; among the last was that given in the Lent and Easter terms of 1939. The lectures, which were given twice a week, lasted two hours, and Wittgenstein spoke entirely without notes. The notes published here are based on those taken by his students at the lectures’ (Editor’s Preface, p. 8).
