The connection between Solov'ëv's philosophy of religion and Schelling's has long been recognized but is difficult to clarify for two reasons. The first is Solov'ëv's nonchalance about citing sources. The paucity of direct references to Schelling in the work of a philosopher who has been called 'the last and most outstanding Russian Schellingian' is quite astonishing. The second reason is the ambivalence toward Schelling in Russian religious philosophy.
