Heidegger: His Life and His Philosophy by Alain Badiou and Barbara Cassin, translated by Susan Spitzer with an introduction by Kenneth Reinhard, is an analysis of one of the twentieth century’s most influential yet controversial philosophers, Martin Heidegger. This extensive work delves deep into the paradoxical existence of Heidegger—an ordinary Nazi and a dedicated member of the provincial petty bourgeoisie, yet simultaneously a seminal thinker whose contributions have left an indelible mark on Continental philosophy.
Badiou and Cassin confront the complex duality of Heidegger’s life head-on, posing challenging questions about the interplay between a philosopher’s intellectual work and their personal and political affiliations. They grapple with whether Heidegger’s domestic life and political associations should inform our understanding of his philosophical contributions or if his intellectual endeavors stand apart from his reprehensible political stance. This inquiry extends beyond Heidegger, touching on the broader issue of how thinkers navigate the tension between the mundane aspects of life and the pursuit of lofty philosophical ideals, as well as the reconciliation of philosophical inquiry with civic engagement.
Central to their examination is an immersive analysis of Heidegger’s correspondence with his wife, Elfride. Through these intimate letters, the authors shed light on Heidegger’s tormented relationships—not only with Elfride but also with Hannah Arendt and other significant women in his life. This personal dimension adds a layer of depth to the understanding of Heidegger’s philosophy, revealing how his private experiences may have influenced his intellectual pursuits. The book does not shy away from exposing the contradictions and complexities within Heidegger’s character, presenting a portrait that challenges simplistic interpretations.
Badiou and Cassin’s employ a conversational style that brings warmth and wit to the discourse, engaging readers in a friendly intellectual duel that is both accessible and deeply insightful. Despite their differing perspectives, the authors maintain a respectful dialogue, exemplifying how strong thinkers can engage in honest and direct debate without hostility. This dynamic interaction enriches the analysis, offering multiple angles from which to consider Heidegger’s life and work.
The book addresses the long-standing debate surrounding Heidegger’s Nazism and its impact on his philosophy. Badiou and Cassin navigate this contentious terrain with care, seeking to move beyond the entrenched positions of staunch defenders and outright detractors. They aim to transcend the deadlock by providing a thoughtful examination of the subtle connections between Heidegger’s fundamental ontology and his personal relationships, particularly those of an intellectual and amorous nature. In doing so, they illuminate how his philosophical concepts may interconnect with his experiences and actions, offering a more integrated understanding of his thought.
Kenneth Reinhard’s introduction sets the stage for this exposition, highlighting the significance of the authors’ endeavor and their contribution to Heidegger studies. The translation by Susan Spitzer captures the essence of Badiou and Cassin’s prose, maintaining the clarity and power of their arguments while making them accessible to an English-speaking audience.
Heidegger: His Life and His Philosophy is a valuable resource for students of Heidegger specifically and for anyone interested in twentieth-century German and French thought more broadly. The book’s extensive scholarship is evident in its detailed examination of Heidegger’s letters and the careful consideration of historical context. The authors’ deep engagement with Heidegger’s work and their willingness to confront difficult questions make this book a significant contribution to philosophical literature.
The work invites readers to reflect on the broader implications of a philosopher’s personal life on their intellectual legacy. It challenges the notion of separating a thinker’s ideas from their actions, encouraging a wider approach to understanding philosophical contributions. By examining the intimate aspects of Heidegger’s life, Badiou and Cassin provide insights into how personal relationships and societal pressures can shape, and sometimes distort, philosophical inquiry.
this book is BOTH about Heidegger and a reflection on the role of the philosopher in society, the responsibilities that come with intellectual pursuit, and the complex exchange between personal convictions and public actions. It serves as a reminder that philosophers, like all individuals, are situated within a particular historical and social context that influences their thinking and behavior.
Heidegger: His Life and His Philosophy is a compelling and thought-provoking work that invites readers to engage deeply with challenging questions. It shows the enduring relevance of philosophy and the importance of critically examining the lives of those who shape our intellectual landscape. Through their research and engaging dialogue, Alain Badiou and Barbara Cassin have created a work that is sure to spark continued discussion and reflection on Heidegger’s legacy and the broader relationship between philosophy and politics.
