Consciousness and Mental Life

In this book Campbell concentrates on five key religious symbols -- the pillar, triad, triangle, cross, and serpent -- that are found in all the world's great religions, in many periods of history. He considers why these emblems were chosen as symbols of religious ideas, what they originally represented, when they were first adopted, why they came into such wide use, what they mean now and how and why the meanings of these symbols changed from their original values to their present ones.
