Prologue.
Carl Gustav Jung is a Swiss psychiatrist. In 1902, he received his medical doctorate from the University of Zurich. He developed complex research under the psychologist Eugen Bleuler, a professor at the university. While interacting with Freud, he began to study in-depth psychology in earnest. In 1908, at the age of 34, he and Freud formed the International Psychoanalytic Society. In 1912, after publishing \'Transformation and Symbolism of the Libido\', he broke up with Freud due to differences in his views on the unconscious. At the age of 44 in 1918, he strengthened his own in-depth psychology by using the expression of ‘the prototype of collective unconsciousness.’ For the archetype study of collective unconsciousness, a comparative work between cultural and religious history is performed. In 1930, a paper dealing with the theoretical consideration of prototypes was presented. In 1935, he led the Eranos Conference, a group of scholars, and interacted with scholars around the world. Focusing on the fact that the prototype of the collective unconscious changes the personality in relation to the self-consciousness, he immersed himself in the study of alchemy. In 1948, the Jung Institute was established in Zurich, Switzerland. In 1953, the complete English edition was published. ‘Psychology of the Unconscious’ was written in 1912 at the age of 38. Jung explores the unconscious world by analyzing Miss Miller\'s phantasy system. In the unconscious desire that transcends time and space, he seeks the identity of human conflict. Through a common bond connected to ancient times, he expands the mechanism of the unconscious to develop intellectual insight. This book is an easy condensed form of a long and difficult text in a summary format.
