This study is stunningly good in more ways than it is possible to summarize briefly: above all, an author, whose erudition is as wide-ranging as his acumen is deep-cutting, has written a timely work in which historical contextualization and philosophical probity are perfectly balanced. John Dewey is rescued by Peter T. Manicas from narrow and reductive readings; thereby he is made available as a truly contemporary contributor to intellectual debates of broad human significance and debates concerning democratic practices and political deliberation, as much as science and inquiry. Dewey's pragmatic naturalism has no more informed, insightful, and indeed eloquent champion than Peter Manicas; and here Manicas is unquestionably at the top of his game.
