"Archie, you are so odd," she said, knowing that he meant to have the subject talked out, and that his will dominated hers, "You spend the day bathing and sailing and writing; you eat and you sleep, and then suddenly you spring a surprise upon me, and show me a letter you have had from Martin. Which is you, the surprise or the Archie that I know?" Archie's mouth was extraordinarily full of rusk and cherry-jam. He politely disposed of them before replying. "But they're both me," he said. "Of course we have all two existences." "Dual personality?" she asked. "Dual fiddlesticks. What I mean is that in everybody there is the conscious self and the subconscious self, but they do not make a dual personality, but one personality. Most people--you, for instance, or Harry, or my mother--transact everything through the conscious personality. For all practical purposes your subconscious self doesn't exist. But in some, and I'm one of them--the subconscious self is accessible. I can reach it if I want. I can make it act. It is the essential life which we all of us contain, and, as such, it is that part of ourselves with which the essential life of those who have quitted this unessential life can communicate. Martin doesn't communicate with that part of me which directs and controls my conversation with you. He speaks to my subconscious self, and, by some rather unusual arrangement, my subconscious life can speak to my conscious life and convey what he says to my hand, or, as once happened, when at Grives I heard him call me, to my ear. I am a medium in fact, though that would usually suggest something charlatanish. I can bring my subconscious life to the surface; sometimes, as when Martin speaks to it, it comes to the surface of its own accord, with strong compulsion over my conscious self." He paused a moment. "It's all very odd," he said. "Until this afternoon, my subconscious self had lain quite quiet for years. Now suddenly it asserts itself and produces that page of writing, because Martin talked to it, and told it to make my hand write. What other explanation is there, unless indeed you imagine that I have merely perpetrated a silly hoax? But I swear to you that something outside myself made me write. Baldly stated, it was Martin who spoke to my subconscious self, and my subconscious self said to my conscious self, 'Take a pencil and write.' I know that is so." Once again Jessie had to anchor herself against this current running out to sea. There was Archie sitting opposite her, large and brown and hungry, talking of things which were altogether fantastic, unless they were dangerous. And somehow, they were not either fantastic or dangerous to him; they were as ordinary as the cherry-jam which he was so profusely eating. She had suddenly come on a great undiscovered tract of country, dubious and full of dangers.
