The chapter intends to present and discuss the profound affinities and important developments that Henz Werner’s theory of symbol formation has favored in the psychoanalytic field. According to Heinz Werner, development proceeds in the sense of a growing differentiation of parts and a growing hierarchization, which is specified in the passage from a syncretic, diffuse, indefinite, and rigid relationship with global reality, to an increasingly differentiated, articulated, defined, and flexible relationship. Through a principle of growing organization, undifferentiated experiences progressively become complex and articulated forms of distinct and differentiated elements in relation to each other. The result is an increasingly evolved adaptation, because it is capable of coping in a stable but flexible way with environmental changes, without being disorganized by them. The famous psychoanalyst Hans Loewald, recognizing the profound influence of Werner’s thought, takes up the conceptual elements of the formation of the symbol and develops them in an original and innovative way with respect to a series of fundamental notions of the theoretical and clinical thought of psychoanalysis: the primary process, the secondary process, and language.
