The monumental work of C. G. Jung, to the creation of which he devoted more than 40 years of his life, is not only a deeply psychological, but also a philosophical study. Jung makes a connection from Gnosticism through alchemical symbolism to philosophical psychology. This book touches on such bold assumptions and hypotheses that it can safely be called a work of the 21st century. Encyclopedic knowledge, phenomenal erudition and originality of thinking allowed C. G. Jung, who relied in his research on both Eastern philosophy and the Western Hermetic tradition , to cover a gigantic range of issues.
