Hans Jonas

An analysis of the Jewish background of an eminent philosopher

Hans Jonas here rethinks the foundations of ethics in light of the awesome transformations wrought by modern technology: the threat of nuclear war, ecological ravage, genetic engineering, and the like. Though informed by a deep reverence for human life, Jonas's ethics is grounded not in religion but in metaphysics, in a secular doctrine that makes explicit man's duties toward himself, his posterity, and the environment. Jonas offers an assessment of practical goals under present circumstances, ending with a critique of modern utopianism.

An international, interdisciplinary, and interreligious retrospective examination of Hans Jonas (1903-1993) that engages his ideas in light of Existentialism, utopian thought, process philosophy and theology, Zionism, and environmentalism.

When Hans Jonas died in 1993 at the age of 89, he was revered among American scholars specializing in European philosophy, but his thought had not yet made great inroads among a wider public. In Germany, conversely, during the 1980s, when Jonas himself was an octogenarian, he became a veritable intellectual celebrity, owing to the runaway success of his 1979 book, The Imperative of Responsibility, a dense philosophical work that sold 200,000 copies. An extraordinarily timely work today, The Imperative of Responsibility focuses on the ever-widening gap between humankind’s enormous technological capacities and its diminished moral sensibilities. The book became something of a cultural shibboleth; he himself became a celebrated public intellectual. For Jonas, this development must have been enormously gratifying. In the 1920s, Jonas studied philosophy with Edmund Husserl and Martin Heidegger at the universities in Marburg and Freiburg, but the Nazi regime’s early attempts at Aryanizing the universities forced Jonas to leave Germany for London in 1933. He emigrated to Palestine in 1935 and eventually enlisted in the British Army’s Jewish Brigade to fight against Hitlerism. Following the Israeli War of Independence (in which he also fought), he emigrated to the United States and took a position in 1955 at the New School for Social Research in New York. He became part of a circle of friends around Hannah Arendt and Heinrich Blucher, which included Adolph Lowe and Paul Tillich. Because Jonas’s life spanned the entire twentieth century, this memoir provides nuanced pictures of German Jewry during the Weimar Republic, of German Zionism, of the Jewish emigrants in Palestine during the 1930s and 1940s, and of German Jewish émigré intellectuals in New York. In addition, Jonas outlines the development of his work, beginning with his studies under Husserl and Heidegger and extending through his later metaphysical speculations about “God after Auschwitz.” This memoir, a collection of heterogeneous unpublished materials—diaries, memoirs, letters, interviews, and public statements—has been shaped and organized by Christian Wiese, whose afterword links the Jewish dimensions of Jonas’s biography and philosophy.

One of the most prominent thinkers of his generation, Hans Jonas wrote on topics as diverse as the philosophy of biology, ethics and cosmology. This work sets forth a systematic philosophy of biological facts, laid out in support of his claim that mind is prefigured throughout organic existence.

"Setting Jonas's work in the historical and philosophical context of his life and times, Levy summarizes Jonas's original achievements in fields as apparently diverse as the history of ancient Gnosticism, the philosophical significance of biology, the problems of ethics in a technological age, and the mysteries of theology, while demonstrating the notable unity of theme and purpose that guided his various fields of inquiry." "Unlike the scattered works, anthologies, and essays that are currently available, Hans Jonas: The Integrity of Thinking provides a much-needed single, coherent overview of the various fields to which Jonas's attention was drawn, bringing out the unified, systematic quality of Jonas's philosophical approach."--BOOK JACKET.

Articulates the fundamental importance of ontology to Hans Jonas’s environmental ethics. Despite his tremendous impact on the German Green Party and the influence of his work on contemporary debates about stem cell research in the United States, Hans Jonas’s (1903–1993) philosophical contributions have remained partially obscured. In particular, the ontological grounding he gives his ethics, based on a phenomenological engagement with biology to bridge the “is-ought” gap, has not been fully appreciated. Theresa Morris provides a comprehensive overview and analysis of Jonas’s philosophy that reveals the thread that runs through all of his thought, including his work on the philosophy of biology, ethics, the philosophy of technology, and bioethics. She places Jonas’s philosophy in context, comparing his ideas to those of other ethical and environmental philosophers and demonstrating the relevance of his thought for our current ethical and environmental problems. Crafting strong supporting arguments for Jonas’s insightful view of ethics as a matter of both reason and emotion, Morris convincingly lays out his account of the basis of our responsibilities not only to the biosphere but also to current and future generations of beings.
