Abstract: William Faulkner delivers his life outlook and history outlook in As I lay dying: Life is simple,monotony and aridity,and day after another largely identical but with minor differences.Humankind history is tragicomedy that readers don't know whether to laugh or cry,full of tribulation,silliness,nonsense,solemn and stirring.Therefore,William Faulkner adopts the writing skill such as allegory and symbol in As I lay dying.
