Karl Jaspers’s axial age thesis refers to a demythologizing revolution in worldviews that took place in the first millennium bce. Although his philosophy has been pejoratively described as ‘Werk ohne Wirkung’, this idea has attracted considerable scholarly attention in recent years. This article aims to critically engage with the very notion of the axial age by looking first at contextual issues, then at the key claims Jaspers makes, before examining the actuality of the thesis and the problem of its characterization (...) as an ‘age’. The conclusion is that Jaspers’s attempt to unify the complex processes of demythologization under the notion of the axial age has produced a myth, and that this continues to have consequences today.
