Abstract : This work tries to make a connection between two literary "thoughts" of two major Italian writers of the 20th century whose similarities bring out the dissimilarities. It presents us with a precise subject; that of the novelistic character, his crisis and the soul searching he does. Then, this matter emphasizes one of the crucial issues of 20th century novel in European culture. This sort of character - excluded, having cut himself from reality - reveals the fragility of the agreement between human being and the world. Thus, the writers we study - Pirandello and Svevo - raise the question of the making and through it, that of the deconstruction of these "men of paper" who are the characters. Pirandello's and Svevo's character is not disclosed at once but is gradually structured in the novel. Nevertheless, their human adventure put them at risk, turning their identity uncertain, making their relationship with the world difficult or even unbearable. That results in a process of deconstruction and sometimes of destruction of which they become the victims. That's why (apart from Pirandello's femalecharacters) they take refuge in sickness, in madness, in delusion or even in the negation of reality.
