Where Voegelin seeks to show the Gnostic nature of modernity, Jonas seeks to show the modern nature of Gnosticism. Jonas draws parallels between ancient Gnosticism and modern, secular existentialism to prove that Gnosticism is existentialist, not that existentialism is Gnostic. For Jonas, both philosophies stress above all the radical alienation of human beings from the world.
