THE EQUINOX Peacock, its oneness is the truer of these two contradictory truths. So for the matter of time and space. All time is filled; all space is filled; the phenomenon is infinite and eternal. This is true even though its singleness makes the duration of the phenomenon but one minimum cogitabile. In short, it is experienced in some other kind of time, some other kind of space. There is nothing irrational about this. Non-Euclidean geometries, for example, are possible, and may be true. It is only necessary to a theory of the universe that it should be true to itself within itself; for there is no other thing outside by which we can check our calculations. Nor is it inconceivable that many of these worlds may exist, interpenetrating. Assume four dimensions, and there is room for an infinite number of them. For though a plane fills a square completely, it must always leave a cube entirely empty. Concerning the laws which govern this new realm we can say nothing here. The most mystics have been led away from the proper line of research, usually by the baser (é.¢, the emotional or devotional) attractions of the Vedana-phenomena which we are about to notice; but perhaps even the best must be baffled by the non-congruity of their Experience with the symbols of language.
