Throughout the history of literature, much has been said about the element of "character" and hence of the "type" in novels and short stories. E. M. Forster's definition of the type is among the most widely accepted definitions. Forster separates character into two categories: round characters and flat characters. However, Georg Lukacs's definition is quite different from Forster's. Lukacs establishes a relationship between character and social, political, and psychological factors. Within the context of such definitions, the heroes in Sabahattin Ali's book of collected short stories, Kamyon (Truck), present a definition of the type that is peculiar to these stories. In this regard, the study reaches the conclusion that the definition of the type is changeable and flexible.
