Treatment induces changes in many ways. The paper attempts to differentiate “transformation” from other modes of change. Descriptively, transformation yields results that could not have been anticipated from the antecedent parts, i.e., the whole is greater than the sum of the parts. Contemplating transformations in psychoanalytic treatment requires some understanding of non-linear activities, although analysts—attuned to reductionism—are usually preoccupied with linear ones. The potential applications with children and adults are outlined.
