How is the history of consciousness alive in each of us? What role does consciousness play in the present civilizational crisis? Why must we participate in, rather than merely endure today’s great cultural transformation? These are key questions for which the Swiss cultural philosopher Jean Gebser (1905 – 1973) has supplied ingenious and compelling answers. In Structures of Consciousness, Georg Feuerstein shows why Gebser’s comprehensive work is one of our century’s most important intellectual contributions to a new self-understanding and profound spiritual reorientation.
