about a definition. With these I have no quarrel; the characterizations are synonymous. His books exhale all evil and all corruption; yet they are as pure as the fabled waters of that crystal spring De Leon sought. They are pervaded by an ever-present, intoxicating sense of sin, ravishingly beautiful, furiously Pagan, frantically lovely; but Machen is a finer and truer mystic than the two-penny occultists who guide modern spiritualistic thought. If we are to subscribe to his curious philosophy, to be discussed later, we must believe that there is no paradox in this. But something of what we are getting at is explained in his own pages, in this opening paragraph from his story, "The White People," in "The House of Souls": "'Sorcery and sanctity,' said Ambrose, 'these are the only realities. Each is an ecstasy, a withdrawal from the common life.'" And, a little later, in this: "'There is something profoundly unnatural about sin ... the essence of which really is in the taking of heaven by storm.'" One gathers from a general vagueness on the subject that sin is not popular in these times. There are, of course, new sins and advanced sins and higher sins, all of which are intensely interesting. The chief puzzle to the lay mind is why they should bear these names, since they are usually neither new, advanced and high, nor particularly sinful. I am speaking of sin as an offense against the nature of things, and of evil in the soul, which has very little to do with the sins of the statute book. Sin, according to the same Ambrose I have quoted, is conceivable in the talking of animals. If a chair should walk across a room, that would be sinful, or if a tree sat down with us to afternoon tea. The savage who worships a conjurer is a far finer moralist than the civilise who suspects him—and I use the name moralist for one who has an appreciation of sin. This is not the sin of the legal code. Ambrose I conceive to be Arthur Machen. There are only two realities; sorcery and sanctity—sin and sainthood—and each is an ecstasy. Arthur Machen's is the former. Perhaps his most remarkable story—certainly I think his most terrible story, is "The Great God Pan," at first published separately with "The Inmost Light"; now occurring in "The House of Souls." It is the story of an experiment upon a girl, as a result of which, for a moment, she is permitted a sight of the Great God, beyond the veil, with shocking consequences. Yet it is told with exquisite reticence and grace, and with a plausibility that is as extraordinary as it is immoral. Here is the conclusion of that story:
