"Event,"aphilosophical concept,has entered literary realm and become a vital concept.This article attempts to clarify it in modern thoughts.In the dimension of discourse event,the reference event of literature arises through its structure and intention,reinvesting speech,discourse,work and literature with meanings attached to being-itself,thus literature discourse becomes event which creates new meaning and refers to the world.In the dimension of truth event,Nietzsche,Heidegger and modern French thinkers declare that literature is truth event,which means that meaningful literature-event brings up meaningful life-event.It is the gift that literature and philosophy could give us,which makes thought event and life event reliable.
