Abstract

This essay situates Gregory’s treatment of the soul—especially, but not exclusively, in his dialogue On the Soul and the Resurrection—within the philosophical tradition of treatises On the Soul (περὶ ψυχῆς, to which he significantly added the Christian component περὶ ἀναστάσεως) and in conversation with Origen’s complex psychology. While Origen never wrote a work On the Soul, for precise reasons, he did write one On the Resurrection. His older contemporary Tertullian composed both a work On the Soul and one On the Resurrection. Gregory opted for a synthesis—not in two separate treatises, but in the same dialogue—of the philosophical genre On the Soul with the Christian (for him Origenian) genre On the Resurrection (which in his view, as in Origen’s, coincided with restoration-apokatastasis) within the framework of a remake of a Platonic dialogue—namely, the Platonic dialogue on the immortality of the soul par excellence, the Phaedo. An investigation into the meaning of restoration with respect to the soul will be conducted in the light of Gregory’s philosophical definition of the soul and of the Platonic ideal of harmony and unity that are paramount in Gregory’s doctrine of the soul and nous. I shall finally tease out the role of the soul in what I call Gregory’s ‘theology of freedom’, deeply rooted in Plato’s philosophy, and the influence that he seems to have exerted on Evagrius’s theories of the threefold resurrection (of body, soul, and nous) and of the subsumption of body into soul and soul into nous (the so-called ‘unified nous’): it will be argued that the Christian Neoplatonist Eriugena was right to trace the latter doctrine back to Gregory of Nyssa.
