"Appearances vs. Facts

The phenomenon of the disappearance of a ship, hull first, as it recedes from view, is caused by the same law of foreshortening as that which governs the disappearance of the rail, or causes the two rails to appear to approach each other. If we should make calculations on the basis of the appearance instead of on the basis of the fact that the rails do not approach, but only seem to, we necessarily draw false conclusions. This is precisely what the astronomers do. They conclude from appearances rather than from facts." -- The Cellular Cosmogony,  Cyrus Teed
