Book excerpt: This volume explores the role of some of the most prominent twentieth-century philosophers and political thinkers as teachers. It examines how these teachers conveyed truth to their students against the ideological influences found in the university and society. Philosophers from Edmund Husserl and Hannah Arendt to political thinkers like Eric Voegelin and Leo Strauss, and their students such as Ellis Sandoz, Stanley Rosen, and Harvey Mansfield, are in this volume as teachers who analyze, denounce, and attempt to transcend ideology for a more authentic way of thinking. What the reader will discover is that teaching is not merely a matter of holding concepts together, but a way of existing or living in the world. The thinkers in this volume represent this form of teaching as the philosophical search for truth in a world deformed by ideology.
