There is however another and a fourth kind, which we have lately seen springing up among those who flatter themselves with the appearance and form of anchorites, and who in their early days seem in a brief fervour to seek the perfection of the Coenobium, but presently cool off, and, as they dislike to put an end to their former habits and faults, and are not satisfied to bear the yoke of humility and patience any longer, and scorn to be in subjection to the rule of the Elders, look out for separate cells and want to remain by themselves alone, that as they are provoked by nobody they may be regarded by men as patient, gentle, and humble: and, this arrangement, or rather this lukewarmness never suffers those, of whom it has once got hold, to approach to perfection. For in this way their faults are not merely not rooted up, but actually grow worse, while they are excited by no one, like some deadly and internal poison which the more it is concealed, so much the more deeply does it creep in and cause an incurable disease to the sick person. For out of respect for each man's own cell no one ventures to reprove the faults of a solitary, which he would rather have ignored than cured. Moreover virtues are created not by hiding faults but by driving them out.
