Inexcusable Omissions explores the work of Clarence Karier and his impact on critical scholarship in the history of U.S. education. Twenty authors contribute essays that examine Karier’s influence on the study of a wide range of issues central to the field, articulate the theoretical approaches that have guided Karier’s inquiry, and engage the reader in biographical reflection. The essays converge on the complexities of new liberal social and educational theory and the impact that these ideas have had on the development of the American public school system. This is the landscape of the humanity and legacy of Clarence Karier as a historian of democracy’s conscience and one of its most committed educators.
