Zettel, an en face bilingual edition, collects fragments from Wittgenstein's work between 1929 and 1948 on issues of the mind, mathematics, and language.

"The editors have put together from Wittgenstein's 'slips' a remarkably cohesive book. . . . and the volume contains the usual facing pages of the original German for ready reference. . . . The work is in keeping with his aim, expressed in the Investigations, not 'to spare other people the trouble of thinking, but if possible to stimulate someone to thoughts of his own.' He provides stimulation—and frustration—in his explorations into issues of mind, mathematics, and language, with some delightfully terse remarks about the thoughts of others. . . . One of the most important volumes in the Wittgenstein literature."—Choice

"The Zettel contains writing of the very highest philosophical quality. Furthermore, much of this material will help to illuminate just those regions of Wittgenstein's thought that have previously been most difficult to understand. . . . By far the largest number of passages concern the philosophy of mind, precisely the area where more information is a godsend."—Yale Review
