The goal of this work is writing about the importance of the poetic art, especially the tragedy to understand the psyche. The literature, besides showing an epoch, represents in a clear and poetic way the human conflicts. To reach this goal, we went through some literary works – Edipo King, by Sofocles, Hamlet and Macbeth by Shakespeare; Goriot Father by Balzac; Twenty Four Hours in a Woman’s Life by Stefan Zweig – extracting from them some fragments in which human sufferings (...) are explicit. We checked the importance of the speech in the emotions relief. We verified in the psychoanalytic and literary speeches that the poetic art seems to illuminate Freud’s steps in such a way that the poets anticipated the technical and psychoanalytic theory. (shrink)
