From the earliest days of man there has endured the conviction that there is an order of existence which is entirely strange to him. It does indeed seem that the strict order of the visible world is only a semblance, one providing certain gross materials which become the basis for subtle improvisations of invisible powers. Hence, it may appear to some that a leafless tree is not a tree but a signpost to another realm; that an old house is not a house but a thing possessing a will of its own; that the dead may throw off that heavy blanket of earth to walk in their sleep, and in ours. And these are merely a few of the infinite variations on the themes of the natural order as it is usually conceived.
But is there really a strange world? Of course. Are there, then, two worlds? Not at all. There is only our own world and it alone is alien to us, intrinsically so by virtue of its lack of mysteries. If only it actually were deranged by invisible powers, if only it were susceptible to real strangeness, perhaps it would seem more like a home to us, and less like an empty room filled with the echoes of this dreadful improvising. To think that we might have found comfort in a world suited to our nature, only to end up in one so resoundingly strange!
