Which scholar was most directly influenced by Jung's ideas?

Joseph Campbell is the scholar most directly influenced by Jung's ideas. He extensively explored themes of mythology, the hero's journey, and archetypes, all of which are rooted in Jungian psychology. Campbell's work, particularly in "The Hero with a Thousand Faces," draws heavily on Jung's concepts of the collective unconscious and the significance of archetypal symbols in stories and myths across various cultures.

This influence is evident in Campbell's approach to analyzing myths as universal narratives that reveal deeper truths about the human experience. His incorporation of Jungian concepts allowed him to articulate how these archetypal patterns resonate across different societies, providing insights into shared human psychology and the commonalities in storytelling.

While Carl Rogers, another prominent psychologist, and Sigmund Freud, who is known for psychoanalytic theory, have their own unique frameworks, they were not as directly tied to Jung's notion of the collective unconscious and archetypal imagery in the way that Campbell was. Jung himself obviously cannot be considered influenced by his own ideas, and his interactions were foundational rather than derivative in nature.
