Certain connotations of ‘working at the frontier’ for the practicing psychoanalyst and for psychoanalysis are discussed in terms of movement along spatial and temporal dimensions. I then selectively highlight three currently significant frontier areas: moving between psychoanalysis and psychotherapy; psychoanalysis under conditions of terror and social traumatization; and the pursuit of the definitive as against the elusive subject. I suggest ‘the use of the analyst’ as the theme that underlies and epitomizes analytic presence and activity at these frontiers. Psychoanalysts are ‘used’ in innumerable ways, but especially by surviving the destructiveness—deliberate and unconscious, real and symbolic—aimed at them. The psychoanalytic presence at these frontiers fashions and reaffirms its unique, life-embracing stance out of chaotic formlessness.
