The purpose of this chapter is to demonstrate the applicability and utility of Lacan’s scheme of discourses (2007) in group-as-a-whole work. First, I will outline Lacan’s theory of the four discourses. Following this, I will address some applications of Lacan’s ideas that have been dealt with by other writers and finally I will provide examples of discourse theory as it might be applied to group-as-a-whole work.
