Book excerpt: Gnosis, in the hands of Roberts Avens, is a perennial philosophy of the heart. This book provides a readable, uncomplicated, and reliable introduction to Gnostic thought in the works of Martin Heidegger and James Hillman. As a psychological philosopher, Avens brings fresh meaning to the basic gnostic ideas about angels, salvation through knowledge, and the world as alive and ensouled. Therapies that encourage personified images and ecology movements concerned with the soul in things can find a profound philosophical ground in this new Gnosis.Third, revised edition
