By 1900, Freud had formulated an original and operational method of psychoanalytic treatment and research: the technique of free association. In 1912–1915 and later writings, he recommended it as a fundamental procedure and process, called the fundamental rule, in psychoanalytic therapy. In recent years, free association as a method has been variously misrepresented, misunderstood, and denied by some schools of psychoanalysis. This paper reviews the history of free associations and argues for upholding the continuity and relevance of Freud's fundamental methodology and for a renewal of interest in reciprocal, i.e., interactive and interpersonal, free association.
