This article considers how early Alexei Losev dealt with the concepts of hesychasm, Palamism, and Name-Glorification. It reveals a range of important sources that Losev employed in his essay “Onomatodoxy” while developing his formulas of hesychasm and Name-Glorification, elaborating on the concept of absolute symbolism and touching on his teaching about universals. These sources include “Synodikon of Orthodoxy,” “Philokalia,” and Pavel Florensky’s essay “Onomathodoxy as a Philosophical Premise.” Although Losev follows the main framework of Florensky’s project in his “Onomatodoxy” (1921–1922)—treating Palamism and Name-Glorification as derivatives of Platonism and comprehending the nature of applying the notion “God” to the divine essence and energies—he differs from Florensky in his interpretation of the structure of symbol. In Losev’s later work, “Essays on Ancient Symbolism and Mythology” (1930), he exchanges his understanding of the correlation between Palamism and Name-Glorification with Platonism, which directly correlates with Losev’s changed attitude toward Florensky. However, in the “Essays,” the specific interpretation of the application of the notion “God” to the essence and energies, dating back to Florensky, is preserved.
