The controversies that Harcourt reviews would be terribly important if they referred to the real world. Actually, they refer not to reality but to paper-and-pencil exercises, to spurious problems spawned by inappropriate theoretical concepts. Economic theory has become its own subject matter; academic narcissism reigns. Perhaps to compensate for his highly technical subject matter, Harcourt strains to write in a sprightly style. He uses arch, allusive language. Chapters or sections have headings such as "Main bout, round one," "Mouth guards out while we arrange a return bout," and "Excuse me, Professor Kaldor, but your slip is showing." Unfortunately, attempts at humor are not the same thing as clear exposition.
