'Even though dreams refer to a definite attitude of consciousness and a definite psychic situation, their roots lie deep in the unfathomably dark recesses of the conscious mind. For want of a more descriptive term we call this unknown background the unconscious. We do not know its nature in and for itself, but we observe certain effects from whose qualities we venture certain conclusions in regard to the nature of the unconscious psyche. Because dreams are the most common and most normal expression of the unconscious psyche, they provide the bulk of the material for its investigation.' -- C. G. Jung, 'On the Nature of Dreams' In 'Individual Dream Symbolism in Relation to Alchemy,'...the material consists of extracts from a series of some 400 dreams and visions, covering a period of ten months in the analysis of 'a young man of excellent scientific education.' In this section of 185 pages, eighty-one dreams and 'visual impressions' are discussed in such detail, and with such a wealth of associated material from religious symbolism all over the world, and such variety and richness of illustration, as to completely defy any attempt at an adequate review. Perhaps the simplest and truest comment to make is that it furnishes a liberal education in the labyrinthine ways of the human psyche! -- Review of Religion These paperback editions of C. G. Jung's writings are chosen from the Collected Works, translated by R.F.C. Hull and published in twenty-one volumes as Bollingen Series XX. The excerpts are selected and grouped thematically to introduce Jung's writings on issues and themes of contemporary interest.
