"All life upon the stage"; the Theatrum Mundi. In this volume, a seventeenth century metaphor is revisited and is seen as applying to all art in all times. In the "magic mirror of art" the human being discerns the hidden spheres of human life and commemorates and celebrates its glorious victories and mourns its ignominious defeats. Let us rediscover Art as a witness to the human predicament as well as a celebrant of humanity's most sublime moments. This is the invitation of this collection of studies by A-T. Tymieniecka, Hanna Scolnicov, Muella Erkilic, Matt Landrus, Patricia Trutty-Coohill, Monika Bakke, David Brubaker, Tammy Knipp, Howard Pearce, Ellen J. Burns, G. Backhaus, Ethan J. Leib, Lawrence Kimmel, Ingrid Scheibler, Gottfried Scholz, L.F. Werth, A. Carillo, M. Statkiewicz, K. O'Rourke, B. Meyler, H. Meltzer, Jiuan Heng, W.V. Davies. Art as mirror of life, human life as participating in a stage play, corresponds to the fervent search human being of the causes, reasons, puzzles of our existence which elude us in the concrete life. This XVII c. conception of Theatrum Mundi opens as this volume shows a fascinating field of investigation for our times.
