Résumé en anglais:

Symeon the New Theologian has developed, in the end of tenth and the begenning of the eleventh byzantine century, a coherent anthropology in resonance with his monastical and mystical experience. This short article will focus on one aspect of that which we can call a theological humanism : That is to say the emergence of the concept of subject-one. This human agent-one acting through multiple operations manifests the tri-unity of the nature of the soul. A brief comparison with Proclus' Commentary of Plato's Parmenide will contribute to indicate the presence of platonician materials as a characteristic feature of the Byzantine Mystical Theology.
