Modern writers such as William Faulkner, Ernest Hemingway, Sigmund Freud, Samuel Becket, Flaubert, Dostoevsky, Joyce, Lawrence, and Eliot directly influenced the form, content, and style of Saul Bellow’s novels, but Bellow’s approach towards existentialism as a literary mode was against the tradition. Saul Bellow in his novels shows that at the inside of existential alienation his protagonists remain optimistic till the end. His stories end not in fragments of frustration, but with a redemptive vision of humanity. The thesis of the paper at hand is to demonstrate and establish how Saul Bellow manipulates his fictionist approaches in the novels Dangling Man, The Victim and Seize the Day, being influenced by the philosophy of existentialism, and how much he is different in his approach compared to other traditional existentialist writers
