Eight diseases of the rational soul
Evagrius opens his list of thirty-three definitions by naming eight diseases of the rational soul, each defined as a disposition, vice, movement, or ignorance that hinders virtue and knowledge of God.
Jaundice is the worst disposition of the rational soul, by which it sees God and the contemplation of the things that have come to be in a distorted way.
Opisthotonos is a vice of the rational nature, by which it becomes hard to bend toward virtue and the knowledge of God.
Sphakelismos is a boiling and a movement of anger that throws the reasoning part of the soul into confusion.
Blindness is ignorance of the mind that does not lay hold of the practical virtues and the contemplation of the things that have come to be.
Paralysis is a difficulty of movement in the rational soul toward the practical virtues.
Gonorrhea is a slackness of the rational soul, by which it habitually casts away the words of spiritual teaching.
Sitting-down is a weakness of the rational soul, by which it habitually casts away the virtues that contribute to the formation of Christ.
Leprosy is unbelief of the rational soul, by which, though handling the words, it is not fully assured.

Ὀπισθότονος, ἔστι κακία φύσεως λογικῆς, καθ' ἣν δυσκαμπὴς γίνεται πρὸς ἀρετὴν καὶ γνῶσιν τὴν τοῦ Θεοῦ. Γʹ. Σφακελλισμὸς, ἔστι ζέσις καὶ κίνησις θυμοῦ τὸ λογιστικὸν μέρος τῆς ψυχῆς ἐκταράττουσα. ∆ʹ. Τυφλότης, ἔστιν ἄγνοια τοῦ νοῦ, ταῖς πρακτικαῖς ἀρεταῖς καὶ τῇ τῶν γεγονότων θεωρίᾳ μὴ ἐπιβάλλουσα. Εʹ. Παράλυσις, ἔστι δυσκινησία λογιστικῆς ψυχῆς πρὸς τὰς πρακτικὰς ἀρετάς. ϛʹ.

Ἀποκάθισις, ἔστιν ἀδυναμία λογικῆς ψυχῆς, καθ' ἣν τὰς συντελούσας ἀρετὰς πρὸς τὴν μόρφωσιν τοῦ Χριστοῦ εἴωθεν ἀποβάλλειν. Ηʹ. Λέπρα ἀπιστία ἐστὶν λογικῆς ψυχῆς, καθ' ἣν οὐ πληροφορεῖται ψηλαφῶσα τοὺς λόγους.
