In the book by sister Teresa Obolevitch, Professor of the Krakow University, the formation and development of the two basic lines within Russian philosophy is shown, i.e., of Soloviev’s «all-unity» system and of Archpriest G. Florovsky’s «Neopatristic synthesis». The author tracks down their intertwinement up to the 21st-century works by S. S. Horuzhy. Like Fr. Thomas Merton, wide known in the West, Horuzhy also showed up a deep interest in Hesychasm, Zen and their spiritual practices and techniques. Prof. Obolevitch believes that Florovsky had not proposed clear-cut criteria for building up a Neo-patristic synthesis of the present-day Russian thought. Besides Horuzhy, no prominent adherents of this trend of thought are to be seen in the most recent history of Russian thought.
