Abstract: In the literary history of 20th century, Kafka can be regarded as the greatest master in creating weak characters. Being weak himself, Kafka can be thought of as the representative of the weak. By describing his own inner feeling and experience of fear, Kafka not only exposes the consciousness of existence but also creates such classical characters as K. The article tries to analyze his narration of Existential aesthetics from the following aspects: the disclosure of the nature of Being, the exposure of the conflicting world and the reformation of the traditional literary narration.  

Key words:  the weak, fear, Existential aesthetics
