On this day, 64 years ago, June 6, 1961 (April 23, 1961 in the lunar calendar), the pioneer of psychiatry Carl Gustave Jung passed away. On June 6, 1961, Carl Gustav Jung, one of the most outstanding pioneers of modern analytical psychiatry, died in Switzerland at the age of 85. After receiving training from Sigmund Freud, Jung established his own theoretical system. Freud maintained that most spiritual problems originated from sexual conflict in infancy and that religion did not play a major role here. Jung's theory insists on emphasizing the importance of man's natural impulse to religion, and that everyone can absorb the common feelings of the entire human race. These feelings exist in the subconscious mind. This theory prompted Jung to study folklore and tribal religious rituals as keys to unlocking the secrets of human thinking and unconscious processes.
