ABSTRACT
The Ancient Greeks are said to be the first in the Western world to connect the notion of the unconscious with soul. The notion of the unconscious came into play when Gottfried Wilhelm Leibniz attempted to integrate the idea of the inner-mind and the outer god. He used the terms “petites perception” and “unconscious and dark perceptions” as synonyms for the unconscious, which in “apperception” become conscious. The 19th century brought about a more differentiated understanding of the unconscious. The unconscious is the realm of suppressed memories and emotions, and also of socially unacceptable wishes, desires and ideas. In contrast with Anna Freud, C. G. Jung maintained a connection with the ancient formulation of the soul and the idea of the unconscious as having both universal and individual components, as developed by Carus, which he translates into the collective and the individual unconscious.
