The Twelve Books on the Institutes of the Cœnobia, and the Remedies for the Eight Principal Faults

I thought it well to insert these things in this little work of mine, that we might learn, not only by reason, but also by examples, about the force of temptations and the order of the sins which hurt an unfortunate soul, and so might be more careful in avoiding the snares and manifold deceits of the enemy. For these things are indiscriminately brought forward by the Egyptian fathers, that by telling them, as those who are still enduring them, they may disclose and lay bare the combats with all the vices, which they actually do suffer, and those which the younger ones are sure to suffer; so that, when they explain the illusions arising from all the passions, those who are but beginners and fervent in spirit may know the secret of their struggles, and seeing them as in a glass, may learn both the causes of the sins by which they are troubled, and the remedies for them, and instructed beforehand concerning the approach of future struggles, may be taught how they ought to guard against them, or to meet them and to fight with them. As clever physicians are accustomed not only to heal already existing diseases, but also by a wise skill to seek to obviate future ones, and to prevent them by their prescriptions and healing draughts, so these true physicians of the soul, by means of spiritual conferences, like some celestial antidote, destroy beforehand those maladies of the soul which would arise, and do not allow them to gain a footing in the minds of the juniors, as they unfold to them the causes of the passions which threaten them, and the remedies which will heal them.
