ABSTRACT
This introductory chapter is an overview of the concept of differentiation of self, the cornerstone of Bowen theory. It will be placed in the context of Bowen theory as a whole. Bowen theory views the family as an emotional unit that has evolved, like all living systems. The elegance and utility of the concept of differentiation, and of Bowen theory in its entirety, are that they describe the basis of individual functioning in relation to others within the emotional systems of the family, occupation, community, and larger society.
