A groundbreaking book that explores how astrology can inform our understanding of the events that have shaped our world—the inspiration for the docuseries Changing of the Gods . In these pages, distinguished philosopher and cultural historian Richard Tarnas traces the connection between cosmic cycles and archetypal patterns of human experience. Based on thirty years of meticulous research, and on thinkers from Plato to Jung, Cosmos and Psyche explores the planetary correlations of epochal events like the French Revolution, the two world wars, and September 11. This brilliant book points to a radical change in our understanding of the cosmos, shining new light on the drama of history and on our own critical age. It opens up a new cosmic horizon that reunites science and religion, intellect and soul, modern reason and ancient wisdom. Whether read as astrology updated for the quantum age or as a contemporary classic of spirituality, Cosmos and Psyche is a work of immense sophistication, deep learning, and lasting importance.
