In the article "All that occurs on the other scene. Subjectivity in the psychoanalysis of Jacques Lacan, the question of responsibility and motives of action" the author would like to draw readers' attentions to the question of subjectivity in the theory of the French contemporary psychoanalyst Jacques Lacan. It is a matter of fact that in all his career Lacan focused on the human subject and in this field developed very interesting reflection. A comprehensive look at the lacanian theory of the subject of unconscious may help us to tease out the difference between his conception and others, not only the psychoanalytical, but also philosophical. In his article the author tries to follow the main topics and attempts to explore such issues as the Freudian discovery of the unconscious, the evolution of the concept of unconscious by Lacan and its transformations put in the context of the investigations about subjectivity, not as a reflection about one definition, but rather as a complicated process of the constituting of subjectivity.
