Hans Jonas' memories are the moving document of a life that spanned almost the entire 20th century. Vividly and with great tension, Jonas recounts Jewish life during the Weimar Republic, his emigration to Palestine, his military service in a Jewish brigade of the British Army, his travels through a devastated Germany, and his time in Canada and the USA, where he writes "The Principle of Responsibility," which makes him famous far beyond the boundaries of academic life.
