The Phenomenon of Life

by Hans Jonas

Published October 1979
A classic of phenomenology and existentialism, The Phenomenon of Life sets forth a systematic and comprehensive philosophy--an existential interpretation of biological facts laid out in support of his claim that the mind is prefigured throughout organic existence. Hans Jonas shows how life-forms present themselves on an ascending scale of perception and freedom of action, a scale reaching its apex in a human being's capacity for thought and morally responsible behaviour.

Mortality and Morality

by Hans Jonas

Published 8 July 1996
Hans Jonas (1903-93) was a German Jew, pupil of Heidegger and Bultmann, lifelong friend and colleague of Hannah Arendt at the New School for Social Research, and one of the most prominent thinkers of his generation. The range of his topics never obscures their unifying thread: that our mortality is at the root of our moral responsibility to safeguard humanity's future. Mortality and Morality both consummates and demonstrates the basic thrust of Jonas's thought: the inseparability of ethics and metaphysics, the reality of values at the center of being.
