Abstract
As the author shows, intellectual history is very different from the history of philosophy; but one wonders if the two kinds of history matter to each other. The author's complete lack of philosophical concerns may, of course, be a virtue, but it is also restrictive and self-defeating. Nevertheless, the book may well stand as the authoritative treatment of the history of Comte's positivism—an idea which, Simon declares at the outset, had little to recommend it but which did manage to have a history. The book is written with great attention to detail and contains a long, well-assembled and very valuable bibliography. The chapters on Mill and other English thinkers are particularly interesting, and will probably settle some old disputes about the impact of positivism in nineteenth-century England.—C. D.
