Carl Gustav Jung (1875–1961) - Swiss psychologist, psychotherapist, philosopher, sociologist and cultural scientist - one of the outstanding scientists of the twentieth century, student of Sigmund Freud, founder of analytical psychology and psychotherapy, founder and president of the Swiss Society of Practical Psychology. In the present The collection presents works that introduce the reader to the fundamental theoretical principles and main working hypotheses of the author. In these works, Jung outlines his ideas about psychic energy, instincts and the unconscious, the soul and death, libido and complexes, as well as his truly revolutionary theory of synchronicity, which he did not dare to present to his readers and colleagues for a long time. In this avant-garde and largely controversial theory, Jung tried to establish a connection between the discoveries of modern physics and the achievements of analytical psychology in that border area of reality, which to this day remains poorly studied and difficult to understand.
