Jung’s work aimed to provide the field of experimentation with a means of accessing the realm of the soul. In the first part of this book, Jung explains just how much we depend on our unconscious. Consciousness, that most cherished of man’s conquests, is “surrounded by the abyss of the unconscious, as if by a threatening sea”, but meditation on our dreams offers us the possibility of establishing a dialogue with our unconscious. The second part familiarises us with the functions and structures of consciousness and the unconscious. Consciousness makes use of certain functions to ensure orientation in external space: sensation, thought, intuition and feeling. Orientation in external space brings us into contact with shadow, which is the dark and repressed part of the self, recollection, memory, affects... Introversion and extroversion distinguish two primary categories of individual, depending on whether they tend to orientate themselves towards the inner or outer world.The third part is dedicated to dreams and presents a number of examples immersing us in this mysterious world which becomes clearer as we explore interpretations.
