John Cassian, The Institutes XII.30: How when a man has grown cold through pride he wants to be put to rule other people

And when a man whom pride has mastered has fallen through these stages of descent, he shudders at the discipline of the cœnobium, and—as if the companionship of the brethren hindered his perfection, and the sins of others impeded and interfered with his advance in patience and humility—he longs to take up is abode in a solitary cell; else is eager to build a monastery and gather together some others to teach and instruct, as if he would do good to many more people, and make himself from being a bad disciple a still worse master. For when through this pride of heart a man has fallen into this most dangerous and injurious coldness, he can neither be a real monk nor a man of the world, and what is worse, promises to himself to gain perfection by means of this wretched state and manner of life of his.
