It will appear only a jest to say that all religious history has really been a pattern of noughts and crosses. But I do not by noughts mean nothings, but only things that are negative compared with the positive shape or pattern of the other. And though the symbol is of course only a coincidence, it is a coincidence that really does coincide. The mind of Asia can really be represented by a round O, if not in the sense of a cypher at least of a circle. The great Asiatic symbol of a serpent with its tail in its mouth is really a very perfect image of a certain idea of unity and recurrence that does indeed belong to the Eastern philosophies and religions. It really is a curve that in one sense includes everything, and in another sense comes to nothing. In that sense it does confess, or rather boast, that all argument is an argument in a circle. And though the figure is but a symbol, we can see how sound is the symbolic sense that produces it, the parallel symbol of the Wheel of Buddha generally called the Swastika. The cross is a thing at right angles pointing boldly in opposite directions; but the Swastika is the same thing in the very act of returning to the recurrent curve. That crooked cross is in fact a cross turning into a wheel. Before we dismiss even these symbols as if they were arbitrary symbols, we must remember how intense was the imaginative instinct that produced them or selected them both in the East and the West. The cross has become something more than a historical memory; it does convey, almost as by a mathematical diagram, the truth about the real point at issue; the idea of a conflict stretching outwards into eternity. It is true, and even tautological, to say that the cross is the crux of the whole matter.
