Abstract

The book focuses on the thinking of the philosopher of Jewish origins, Hans Jonas (1903-1993), and precisely on his “philosophical biology”. The overall thesis is that this topic, which occupies the second stage of his thinking, is coherent with the previous phase (which focused on ancient Gnosticism), as well as with the following (which was dedicated to the ethics of responsibility). The main evidence supporting this thesis is the key notion of “ontological revolution”, the development of which I try to analyse in Jonas’ published and unpublished writings. This is the first innovative feature of the research. The second is my attempt to compare Jonas’ ideas of life and organism with the reflections of thinkers such as Aristotle, Spinoza, and Whitehead.
