This monograph is the previously un-published and relatively unknown master’s thesis of Archimandrite Robert Taft, SJ. Father Taft asked ECP to publish this volume many years ago but he never finished the edits or bibliography before his passing in 2018. Father Robert Slesinski, a scholar of Russian philosophy in his own right, agreed to posthumously edit the work for publication. It was written in 1956 when Fr Taft was teaching in Baghdad after his early academic studies at Boston College. 130 pages. $15.00.
