Abstract:As one of the greatest writers in the 20th century, Franz Kafka has created a host of impressive images. However, scholars have not paid enough attention to the “assistants” in his writings. The origins of these “assistants” should relate to Kafka’s experience in Yiddish plays, reading, films, and paintings. Correspondingly, his “assistants” display the features of “drama”, “body language” and “subjectivity” , performing functions of intermediaries and generability in the texts. Meanwhile, their comic nature makes the texts panic and meaningless. The innate “subjective deficiency” of the “assistants” and the “lost of the master’s subjectivity” it leads to reveal the existential plight of modern people either as “assistants” or as “masters.”
