This introduction provides an overview of some of the central issues in clinical psychoanalytic theory explored in this section, such as those relating to drives and symbolism, the distinction between the conscious and the unconscious, and the intentionality of defences. The chapters in this section deal with topics ranging from transference and ‘transference neurosis’ to Sigmund Freud’s contributions to psychoanalysis, with particular emphasis on the shifts in the psychoanalytic theory of symbolism since Freud, his drive theory, his core concept of wish fulfilment, and his understanding of mourning, repetition, and the fundamental rule of psychoanalysis. Also discussed are therapeutic transformation and making the unconscious conscious, along with the meaning of inner integration.
