Colin Wilson's classic work is the essential guidebook to the mind-expanding experiences and discoveries of the 20th century. His genius lies in producing a skillful synthesis of the available material - clarifying without simplifying, seeing the occult in the light of reason and reason in the light of the mystical and paranormal. It is a journey of enlightenment. He provides a wide-ranging survey of the subject, a comprehensive history of "magic" and an insightful exploration of our latent powers, and brings his own refreshingly optimistic and stimulating interpretation to the worlds of the paranormal, the occult and the supernatural.
