Chapter XVI.
The answer giving the proofs by which it can be recognized.
John: Your shrewd question has anticipated the subject, which even if you had said nothing must have arisen from our discourse, and therefore I do not doubt that it will be effectually grasped by your minds, since indeed your sharp wits have outstripped our instruction. For the puzzle of any question is easily removed, when the inquiry anticipates the answer, and is the first to travel along the road which it is to follow. And so to the treatment of those faults of which we have spoken above, intercourse with other men is not merely no hindrance, but a considerable help, for the more often that the outbursts of their impatience are exposed, the more thorough is the sorrow and compunction which they bring on those who have failed, and the speedier is the recovery of health which they confer on those who struggle against them. Wherefore even when we are living in solitude, though the incentive to irritation and matter for it cannot arise from men, yet we ought of set purpose to meditate on incitements to it, that as we are fighting against it with a continual struggle in our thoughts a speedier cure for it may be found for us. But against the spirit of fornication the system is different, and the method an altered one. For as we must deprive the body of opportunities of lust, and contact with flesh, so we must deprive the mind of the recollection of it. For it is sufficiently dangerous for bosoms that are still weak and infirm even to tolerate the slightest recollection of this passion, in such a way that sometimes at the remembrance of holy women, or in reading a story in Holy Scripture a stimulus of dangerous excitement is aroused. For which reason our Elders used deliberately to omit passages of this kind when any of the juniors were present. However for those who are perfect and established in the feelings of chastity there can be no lack of proofs by which they may examine themselves, and establish their perfect uprightness of heart by the uncorrupted judgment of their own conscience. There will then be for the man who is thoroughly established a similar test even in regard to this passion, so that one who is sure that he has altogether exterminated the roots of this evil may for the sake of ascertaining his chastity, call up some picture as with a lascivious mind. But it is by no means proper for such a test to be attempted by those who are still weak (for to them it will be dangerous rather than useful), ut conjunctionem femineam et palpationem quodammodo teneram atque mollissimam corde pertractent. Cum ergo perfecta quis virtute fundatus ad illecebram blandissimorum tactuum, quos cogitando confinxerit, nullum mentis assensum, nullam commotionem carnis in se deprehenderit exagitatam, he will have a very sure proof of his purity, so that training himself to this steadfast purity he will not only possess the blessing of chastity and freedom from defilement in his heart, but even if he is obliged to touch the body of a woman, he will be horrified at it.
With this Abbot John brought his Conference to an end, as he saw that it was just time for the refreshment of the ninth hour.
