The mind commands the body and is instantly obeyed. The mind commands itself and meets resistance. The mind commands the hand to move, and it so easy that one hardly distinguishes the order from its execution. Yet mind is mind and hand is body. The mind orders the mind to will. The recipient of the order is itself, yet it does not perform it.
Saint AugustineThough he avoided outright endorsement of the view, fifth-century Church Father Saint Augustine was clearly familiar with the theory of the spherical earth: "They [those who believe that "there are men on the other side of the earth"] fail to observe that even if the world is held to be global or rounded in shape, or if some process of reasoning should prove this to be the case, it would still not necessarily follow that the land on the opposite side is not covered by masses of water."
