Jungian Analyst John Hill on "soul" and "psyche":
John Hill and "What do I mean by the word "soul," here understood as the equivalent of ‘psyche’”? Aristotle understood psyche as the inner life principle of every living being. In his philosophy, soul was not identified with the rational mind, as in modern philosophy. Psyche regulates and bestows form in an increasingly complex manner to all living beings in accord with their species. Referring to the active, organizing life principle in humans, Aristotle’s definition of the psyche approximates to a contemporary definition of the unconscious as a ‘cohesive, active mental structure that continuously appraises life’s experiences.’ Psyche, according to Aristotle, organizes our mental an emotional life, acts as a dynamic system of transformation of personal and collective experiences, and generates the imagination, both sacred and profane. Psyche, in this sense, includes consciousness and the unconscious as a dynamic, interactive, self-organizing process” (2010, Hill, At Home in the World, p. 98).
