This book sets out a new reading of the much-neglected philosophy of Karl Jaspers. By questioning the common perception of Jaspers either as a proponent of irrationalist cultural philosophy or as an early, peripheral disciple of Martin Heidegger, it re-establishes him as a central figure in modern European philosophy.

Giving particular consideration to his position in epistemological, metaphysical and political debate, the author argues that Jaspers's work deserves renewed consideration in a number of important discussions, particularly in hermeneutics, anthropological reflections on religion, the critique of idealism, and debates on the end of metaphysics.
