The fourth volume in the Progress in Self Psychology series continues to explore the theoretical yield and clinical implications of the wok of the late Heinz Kohut.  Learning from Kohut features sections on "supervision with Kohut" and on the integration of self psychology with classical psychoanalysis. Developmental contributions examine self psychology in relation to constitutional factors in infancy. Clinical presentations focusing on optimum frustration and the therapeutic process and on the self-psychological treatment of a case of "intractable depression" elicit the animated commentary that makes this volume, like its predecessors, as enlivening as it is instructive.
