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.

Hans Jonas, a pupil of Heidegger and a colleague of Hannah Arendt at the New School for Social Research, was one of the most prominent phenomenologists of his generation. This carefully chosen anthology of Jonas's shorter writings - on topics from Jewish philosophy to philosophy of religion to philosophy of biology and social philosophy - reveals their range without obscuring their central unifying thread: that as living, biological beings, we are also beings who die, and who must consider the implications for current and future ethical and social relations.

In Book Oneof this four-volume work, Alexander describes a scientific view of the world in which all space-matter has perceptible degrees of life, and establishes this understanding of living structures as an intellectual basis for a new architecture. He identifies fifteen geometric properties which tend to accompany the presence of life in nature, and also in the buildings and cities we make. These properties are seen over and over in nature and in the cities and streets of the past, but they have almost disappeared in the impersonal developments and buildings of the last hundred years. This book shows that living structures depend on features which make a close connection with the human self, and that only living structure has the capacity to support human well-being.
