Abstract :
The reason for human s existence has become the most researched field in philosophy. Philosophers such as Heidegger, Nietzsche, Sartre, Marcel, Ponty, Husserl, Beauvoir, Jaspers, have deepened the idea of existentialism which began with Kierkegaard. Existentialism has also been examined by its various assumptions by different writers and by different written texts such as novel, story and theatre. There are many writers in world literature who reflect existentialist thought to their works such as Sartre, Beauvoir, Camus, Dostoyevski, Kafka, Beckett. In this study, the principal features of existentialist philosophy and existential novel type are described; then Giirsel Korat s four novel with historical level (Zaman Yeti, Giivercine Agzt, Katenderiye, Riiya Korii) are evaluated in the light of existentialism and the characteristics of existential novel. In the study, authenticity of Giirsel Korat s novels were discussed.
