Dr. Carl Gustav Jung (1875–1961) was a Swiss psychiatrist, psychotherapist, and the founder of analytical psychology. One of the most influential thinkers in the history of psychology, Jung developed groundbreaking theories on the unconscious mind, psychological types, dreams, symbols, and the process of individuation. His work expanded the understanding of human behavior by introducing concepts such as the collective unconscious, archetypes, and the psychological significance of myths and religion.
After collaborating with Sigmund Freud in the early years of psychoanalysis, Jung established his own school of thought, emphasizing the role of the unconscious in personal growth and self-realization. His writings have had a lasting impact not only on psychology and psychotherapy but also on literature, philosophy, religious studies, and the arts.
Among Jung's most notable works are Psychological Types, Modern Man in Search of a Soul, Symbols of Transformation, The Archetypes and the Collective Unconscious, and Memories, Dreams, Reflections. The Theory of Psychoanalysis presents his early lectures on psychoanalytic theory and marks an important stage in the development of his ideas that would later shape analytical psychology.
