The author attempts to describe the phenomenon of projection and how a projection can be withdrawn and integrated. The book shows the role of projection in the history of religion and in science as well as how projection works on a primitive level. This leads to the discussion of the projection of evil, the reality of demons and of helpful spirits . The cure for projecting one’s own qualities onto others is reflection. The latter is not possible through efforts of the ego alone, but needs the support of the Self. Projection is the greatest problem in politics, social groupings, and in all human relationships.
