Reik's most famous book, Listening with the Third Ear (1948), describes how psychoanalysts intuitively use their own unconscious minds to detect and decipher the unconscious wishes and fantasies of their patients. According to Reik, analysts come to understand patients most deeply by examining their own unconscious intuitions about their patients. In his psychoanalytic autobiography Fragments of a Great Confession (1949), Reik turned a psychoanalytic ear toward his own life, interpreting his inner conflicts and their influence on his writing and relationships.
