"Then there are the appearances Laurie saw; and the extraordinary effect they finally had upon him. Oh! yes; at the time, on the night of Easter Eve, I mean, I was absolutely certain that the thing was real, that he was actually obsessed, that the thing—the Personality, I mean—came at me instead, and that somehow I won. Mr. Cathcart tells me I'm right—Well; I'll come to that presently. But if it didn't happen, I certainly can't explain what did; but there are a good many things one can't explain; and yet one doesn't instantly rush to the conclusion that they're done by the devil. People say that we know very little indeed about the inner working of our own selves. There's instinct, for instance. We know nothing about that except that it is so. 'Inherited experience' is only rather a clumsy phrase—a piece of paper gummed up to cover a crack in the wall.
"And that brings me to my third theory."
Maggie poured out for herself a second cup of tea.
"My third theory I'm rather vague about, altogether. And yet I see quite well that it may be the true one. (Please don't interrupt till I've quite done.)
"We've got in us certain powers that we don't understand at all. For instance, there's thought-projection. There's not a shadow of doubt that that is so. I can sit here and send you a message of what I'm thinking about—oh! vaguely, of course. It's another form of what we mean by Sympathy and Intuition. Well, you know, some people think that haunted houses can be explained by this. When the murder is going on, the murderer and the murdered person are probably fearfully excited—anger, fear, and so on. That means that their whole being is stirred up right to the bottom, and that their hidden powers are frightfully active. Well, the idea is that these hidden powers are almost like acids, or gas—Hudson tells us all about that—and that they can actually stamp themselves upon the room to such a degree that when a sympathetic person comes in, years afterwards, perhaps, he sees the whole thing just as it happened. It acts upon his mind first, of course, and then outwards through the senses—just the reverse order to that in which we generally see things.
"Well—that's only an illustration. Now my idea is this: How do we know whether all the things that happened, from the pencil and the rappings and the automatic writing, right up to the appearances Laurie saw, were not just the result of these inner powers.... Look here. When one person projects his thought to another it arrives generally like a very faint phantom of the thing he's thinking about. If I'm thinking of the ace of hearts, you see a white rectangle with a red spot in the middle. See? Well, multiply all that a hundred times, and one can just see how it might be possible that the thought of ... of Mr. Vincent and Laurie together might produce a kind of unreal phantom that could even be touched, perhaps.... Oh! I don't know."
Maggie paused. The girl at her side gave an encouraging murmur.
"Well—that's about all," said Maggie slowly.
"But you haven't—"
"Why, how stupid! Yes: the first theory.... Now that just shows how unreal it is to me now. I'd forgotten it.
