Authenticity and theatricality: Andrzej Falkiewicz’s model of homo theatralis in the context of Helmuth Plessner’s criticism of radicalismThe aim of this work is to confront Andrzej Falkiewicz’s model of “homo theatralis” and—to a lesser degree—“being-as-metaphor” with Helmuth Plessner’s criticism of radicalism. In the first step the author shows generally the problem of “self” and moral sources of identity. In the second step the author analyzes the concept of “homo theatralis” “theater man” and “being-as-metaphor” by the Polish writer, critic, and philosopher (...) Andrzej Falkiewicz—Leszek Nowak’s cooperator. In the third step the author is trying to connect Falkiewicz’s ideas with Helmuth Plessner’s model of radicalism connected with his concept of commonwealth and society and difference between them. Then the author answers the question of the possibility of freedom in building our individual moral horizon. (shrink)
