For Kris, central to creativeness is a regression of ego functions in the purposive and controlled service of creativity, involving "a continual interplay between creation and criticism, manifested in the painter’s alternation of working on the canvas and stepping back to observe the effect" (p. 253). So the process of creation is, au fond, a fluctuation of functional ego regression and control. Kris adds, "When regression goes too far, the symbols become private, perhaps unintelligible even to the reflective self; when, at the other extreme, control is preponderant, the result is described as cold, mechanical, and uninspired" (p. 254). For anyone interested in exploring the psychodynamic aspects of artistic creation, this book definitely would be the place to begin, after gaining some knowledge of the fundamentals of ego psychology.
