Grennan provides a balanced summary of existing theories and methods in the study of storytelling, providing a new explanation of the structure of story and discourse, according to established descriptions of intersubjectivity. He explicitly encompasses his explanation of the experience of drawing, visual depiction and imagination (made in Chapter 1) within this intersubjective description of narrative, focusing specifically on the experience of visual narrative. On this basis, Grennan presents a new epistemological system of discourse characterised as narrative.
