I laid my hand on his arm; he turned quite without surprise; and indeed it is possible that to him, whose inner life had soaked up the outer life, a parting of years was a parting from forenoon to afternoon. He stood holding the door half open, as though he would keep me from entering; and would perhaps have parted from me without further words had I not said: ‘Owen Aherne, you trusted me once, will you not trust me again, and tell me what has come of the ideas we discussed in this house ten years ago?--but perhaps you have already forgotten them.’ ‘You have a right to hear,’ he said, ‘for since I have told you the ideas, I should tell you the extreme danger they contain, or rather the boundless wickedness they contain; but when you have heard this we must part, and part for ever, because I am lost, and must be hidden!’ I followed him through the paved passage, and saw that its corners were choked, and the pictures gray, with dust and cobwebs; and that the dust and cobwebs which covered the ruby and sapphire of the saints on the window had made it very dim. He pointed to where the ivory tablets glimmered faintly in the dimness, and I saw that they were covered with small writing, and went up to them and began to read the writing. It was in Latin, and was an elaborate casuistry, illustrated with many examples, but whether from his own life or from the lives of others I do not know. I had read but a few sentences when I imagined that a faint perfume had begun to fill the room, and turning round asked Owen Aherne if he were lighting the incense. ‘No,’ he replied, and pointed where the thurible lay rusty and empty on one of the benches; as he spoke the faint perfume seemed to vanish, and I was persuaded I had imagined it. ‘Has the philosophy of the _Liber Inducens in Evangelium Æternum_ made you very unhappy?’ I said. ‘At first I was full of happiness,’ he replied, ‘for I felt a divine ecstasy, an immortal fire in every passion, in every hope, in every desire, in every dream; and I saw, in the shadows under leaves, in the hollow waters, in the eyes of men and women, its image, as in a mirror; and it was as though I was about to touch the Heart of God. Then all changed and I was full of misery, and I said to myself that I was caught in the glittering folds of an enormous serpent, and was falling with him through a fathomless abyss, and that henceforth the glittering folds were my world; and in my misery it was revealed to me that man can only come to that Heart through the sense of separation from it which we call sin, and I understood that I could not sin, because I had discovered the law of my being, and could only express or fail to express my being, and I understood that God has made a simple and an arbitrary law that we may sin and repent!’
