Abstract

Contrary to Favrholdt's opinion, a book that "contains many mistakes" may nevertheless be a good book; it may even be a masterpiece. Thus, although Favrholdt's Interpretation contains many mistakes, it is nevertheless a good book. Unlike most commentaries on the Tractatus, Favrholdt makes a concerted effort to come to grips with the work as a whole. He tries to show that the thesis of extensionality is fundamental, and that the rest of the Tractatus is a working out of the consequences of that thesis. Several of his interpretations are highly questionable, and he has a tendency to give up too easily on some crucial points. But he does give us an original and highly provocative treatment.—A. E. J.
