Carl Jung, a prominent psychologist and psychiatrist of the twentieth century, remarked that "our psyche is only part of nature, and its mystery is limitless." However, for many centuries a person has been stubbornly trying to master this secret, to comprehend the nature of his soul, to find opportunities for healing its ailments. The authors of the proposed book, which is a brief scientific and at the same time almost fiction account of the history of psychology and psychiatry from their origins to the middle of this century, are trying to guide their readers along the complex and winding path of such searches.
