In this commentary, Andy Kaplan discusses with Lois Weiner, Diane Ravitch's latest book "The Reign of Error," which combines scholarly argument and scrupulous research in defense of democratic education. Weiner notes, the book will prove an important resource in the ongoing struggle for the survival of public schooling. Weiner adds, since that struggle concerns not only control of facts and control of logic but also control of the means of persuasion, a review of seven questions posed by Ravitch's book focus on rhetoric. Andy Kaplan closes the commentary with the thought, Lois Weiner is uniquely qualified to assess the ways in which Ravitch's book will prove useful to educators and citizens engaged in the struggle for public control of public education as she is one of America's leading advocates of democratic control of public schools.
