Patient's surface, clinical surface, and workable surface

Surface is a term often used in clinical theory, which seems to have eluded a reliable definition. Freud used the term mostly to denote the analysand's consciousness. This patient's surface does not always coincide with the data the analyst can observe, i.e., the clinical surface. It is proposed that clinical surface be understood, in contrast to other psychoanalytic concepts, as the clinical evidence that does not need conjecture to be grasped cognitively. The concept of "average expectable apperception" is introduced. Workable surface is defined as those aspects of the clinical surface that lend themselves well to the exploration of unconscious dynamics or genesis. Ideas about which surfaces are optimally workable vary according to different schools of technique. The advantages of considering clinical surface the objective anchorage of psychoanalysis as a positive science and of differentiating it from patient's surface and workable surface are discussed.
