Abstract
In this paper, we examine similarities between Sigmund Freud’s tripartite theory of personality to foundational works across various religious and philosophical movements. First, conceptual similarities to the id, ego, and superego are illustrated through scriptural verses and commentators of Judaism, Christianity, and Islam. Next, elements of the tripartite theory in the Eastern religions of Buddhism, Hinduism, and Sikhism are explored. Finally, this Freudian theory is viewed in relationship to various philosophical works from Ancient Greece to modern day. We suggest these earlier tripartite approaches emanating from diverse religious and philosophical movements emerge as a broader universal understanding of man from which Freud could have profited in developing one of his most seminal theories.
