"Studies of the phenomenology of the Self" is one of the most unusual works in Jung's scientific legacy, located at the intersection of philosophy, psychoanalysis, cultural studies and religion. In it, the great scientist refers to the symbolic representation of mental integrity, the ideal historical example of which, according to his theory, is Jesus Christ. This idea allows Jung to explore the multifaceted meaning of the early Christian symbol of the Savior, the Fish, and the philosophy of the dichotomy of images of Christ and the Antichrist.
