Moreover, he could be in two or more places at once, and cause two bodies to occupy the same space-which to us is inconceivable. Stranger still, he might be both alive and dead at the same time-since Past, Present, and Future would be all one to him; the world without beginning or end ...-From the "Geometrical Possibilities," of Abd'el Kasir, of Cordoba, circa. 1050 A.D."
