Beliefs are important because they explicitly or implicitly guide conduct. They are also important for astrology because almost more than anything else they define and "prove" the sun signs that many dismiss as only subjective, imaginative theory. Yet the fact is that the kind of values, worldviews, religious and philosophical beliefs an Aries holds will be different from that of a Libran even if and when those involved claim to subscribe to the same principles or faith. The famous character features attributed to the zodiacal signs are in fact traits based upon a mythic or archetypal core in the unconscious that sends people in certain directions they can never quite avoid. Though only a full birth chart can describe persons in detail, the sun sign which describes will and aspiration is the basis for all the rest. This is no ponderous survey of beliefs, but it is serious about its subject even when it is entertaining and shows the humorous side of its theme. From the sometimes parlour game treatment of astrology this book returns to the study not just its credibility but its spiritual function in telling us who we are and our real options.
