The subject of this paper is a specific form of cosmogony — the conception of cosmogonic objectivation, interpreted as a tragedy or cosmogonic fall. This conception is examined on the basis of the evidence furnished by two sets of materials: firstly, the original texts and paraphrases of the Valentinian Gnostics of the 2ⁿᵈ and 3ʳᵈ centuries AD (Irenaeus Adversus haereses, 1.1.1–1.1.10; Excerpta ex Theodoto, compiled by Clement of Alexandria; and The Gospel of Truth from the Nag Hammadi Library), and secondly, the writings of the Russian philosophers Vladimir Solovyov, Lev Karsavin and Nikolay Berdyaev. The research reveals a series of specific features common to both of these: in particular, the conception of cosmogonic objectivation appears to be connected with the doctrine of the absolute person’s fall, and with the motive of self-alienation.
