弗洛連斯基首先獨立提出了「分聲歌唱」式的創作，這要早於巴赫金針對陀思妥耶夫斯基的創作所提出的複調理論。弗洛連斯基的具體玄學反映了他所說的圓形思維方式和分聲歌唱。圓形思維、分聲歌唱、具體玄學與書信體之間是協調一致的關係。

P. A. Florensky first independently proposed a "heterophony" type of creation, which was earlier than the theory of polyphony that Bakhtin proposed for the artistic creation of Dostoevsky. The specific metaphysics of P. A. Florensky reflected his way of circular thinking and heterophony. Circular thinking, heterophony, specific metaphysics and epistolary genre are surveyed in coordinated relationship.
