The author discusses the various roles of superego function as forces that facilitate or block creative activity. Creative people may be governed by an 'anticreative' superego in which demands for self-provision are stronger than ego ideals to create. Such a situation is often found in creative blocks. Unlike ordinary work in which dedication is derived from the superego, the creative drive comes from the id's instinctual essence and demands a different superego organization. Thus the drive toward creative work is rarely transferable to ordinary work. Weissman disagrees with Kris's formulation of the role of superego in shaping the drive content in creative products. He believes that ego ideal and prohibitive functions of ego have little to do with shaping the drive elements that are allowed to appear in the final work.
