The author states that every literary character, when it is the fruit of real inspiration, reveals not only the basic problems of behavior but also the psychic mechanisms of a mental conflict. He makes a psychoanalytic inquiry into the problems of behavior through comparative analyses of the characters Hamlet, Oedipus, Sigismund and Faust. In all there is an acute problem of decision in the face of the many and different dramatic circumstances that surround each of them. This decision becomes so difficult because the same circumstances that would bring satisfaction of their conscious aims signify the consummation of unconscious strivings ladened with guilt. The author, a Professor in the School of Philosophy of Buenos Aires, develops his ideas in an easily readable and interesting book.
