Jung’s lectures on consciousness and the unconscious — in English for the first time. Between 1933 and 1941, C. G. Jung delivered a series of public lectures at the Swiss Federal Institute of Technology (ETH) in Zurich. Intended for a general audience, these lectures addressed a broad range of topics, from dream analysis and yoga to the history of psychology. They are at the center of Jung’s intellectual activity in this period and provide the basis of his later work. Here for the first time in English is Jung’s introduction to his core psychological theories and methods, delivered in the summer of 1934. With candour and wit, Jung shares with his audience the path he himself took to understanding the nature of consciousness and the unconscious. He describes their respective characteristics using examples from his clinical experience as well as from literature, his travels, and everyday life. For Jung, consciousness is like a small island in the ocean of the unconscious, while the unconscious is part of the primordial condition of humankind. Jung explains various methods for uncovering the contents of the unconscious, in particular talk therapy and dream analysis. Complete with explanations of Jungian concepts and terminology, Consciousness and the Unconscious painstakingly reconstructs and translates these talks from detailed shorthand notes by attendees, making a critical part of Jung’s work available to today’s readers.
