Sigmund Freud’s psychoanalytic theory remains one of the most influential and controversial frameworks in psychology and the humanities. This review revisits the core concepts of Freud’s thought, including the topographical and structural models of the mind, psychosexual stages of development, defence mechanisms, and the interpretation of dreams. Central to his theory is the idea that unconscious processes, formed largely in early childhood, shape human behaviour, emotions, and neuroses. Freud’s model of the psyche—comprising the id, ego, and superego—offers insight into internal conflict and the mechanisms individuals use to cope with anxiety and repression. Despite extensive criticism regarding its scientific validity, gender bias, and overemphasis on sexuality, Freud’s work laid the groundwork for modern psychodynamic therapy and influenced a range of disciplines, from literature and art to film and critical theory. The paper also considers major revisions and expansions by post-Freudian theorists and evaluates psychoanalysis in light of contemporary clinical and cultural perspectives. Ultimately, Freud’s legacy endures not as a fixed doctrine but as a dynamic, evolving tradition that continues to shape how we understand the unconscious, symbolic life, and the complexities of human experience.
