Abstract
Throughout his career, Hans Jonas has reflected on the notion of the human soul and on the concept of man being created in God’s image. A careful analysis of his writings reveals that (approximately) from 1968 he changed his perspective on these topics. Before this year, Jonas used some Gnostic myths to speak about the image of man in relation to God and was concerned that referring to the immortality of the human soul or to the notion of imago Dei could lead to dualistic or pseudo-Gnostic interpretations of the natural world. From 1968 (when Jonas published an article for an American Jewish journal) he started to underline the importance of the Judeo-Christian notion of imago Dei (from the book of Genesis) for his ethical project. Subsequently, he used this concept (derived from the Bible rather than from Gnostic texts) in support of his ethical approach to show the special role that God assigned to humanity to act as a steward of His creation. This article presents the development of Jonas’s contributions on these issues over time, their importance in relation to his ethical project and how he was influenced in the development of his perspective on this subject.
