In this treatise, John the Solitary (ca. 390) enters into a dialogue with two disciples who have come past the beginning stage of the spiritual life and have brought him their struggle against the passions in the life of the inner person (barna a gawwaya). John's description of the life of the soul is outlined here in a framework of the stages of the spiritual life. Included is his analysis of the passions, showing very little if any Evagrian influence. The Dialogue on the Soul is a difficult text. It is hoped that this Syriac-English presentation will enable others to take the discussion forward. John's genial thought merits this."
