The universe is infinite, or so the scholiasts say, and I have seen that it is so. But it is infinite only in certain ways: in space and in potential. It is bounded in time, for time had a beginning—all magi agree—and so it must have an end. As will we. Something in this asymmetry between infinite space and finite time, I think, explains all coincidences, conserving fact as readily as other laws conserve matter and energy. Or perhaps . . . it is only that we are human, and that our human lives are woven together, and are more tightly bound by the action of the loom of human drama.
