Chris Matthew Sciabarra (born February 17, 1960) is an American political theorist based in Brooklyn, New York. He is the author of three scholarly books—Marx, Hayek, and Utopia; Ayn Rand: The Russian Radical; and Total Freedom: Toward a Dialectical Libertarianism—as well as several shorter works. He is also the co-editor, with Mimi Reisel Gladstein, of Feminist Interpretations of Ayn Rand and co-editor with Roger E. Bissell and Edward W. Younkins of The Dialectics of Liberty: Exploring the Context of Human Freedom. His work has focused on topics including Objectivism, libertarianism (particularly the work of Friedrich Hayek and Murray Rothbard), and dialectics. Life Sciabarra was a visiting scholar at New York University from 1989 to 2009, where he earned his BA in history (with honors) in 1982; his MA in Politics in 1983; and his PhD in Political Philosophy, Theory, and Methodology in 1988, under the supervision of Bertell Ollman. In 1999 he became the co-founder and co-editor of the biannual Journal of Ayn Rand Studies, which has been published by Penn State University Press since 2013, and belongs to Liberty and Power, a group weblog at the History News Network. He is the author of a trilogy of books on dialectics and libertarianism. The second of these, published in 1995, is Ayn Rand: The Russian Radical, which explores Ayn Rand's college influences and intellectual roots—particularly the role of Rand's philosophy teacher, philosopher Nicholas Onufrievich Lossky—and argued that Rand's philosophical method was dialectical in nature. In 2013, Pennsylvania State University Press published a second expanded edition of Ayn Rand: The Russian Radical, which includes a new preface, three new appendices (Appendices I and II are "The Rand Transcript" and "The Rand Transcript, Revisited," first published in The Journal of Ayn Rand Studies, and Appendix III constitutes a response to Shoshana Milgram, a recent critic of Sciabarra's historical work. The expanded second edition also includes an expanded section in Chapter XII, "The Predatory State," entitled "The Welfare-Warfare State," which explores Rand's radical critique of US foreign policy).
