Let us try if this can be made clearer by an example. It has been stated before that if iron were made to swim on water by modification of the law of gravity it would be creation of a new substance differing from iron in being of less specific gravity. At the same time, the original iron of normal specific gravity would have disappeared. These processes of creation and destruction would be so unprecedented that we should justly call them violations of the ordinary laws of nature. But at least we should then expect that the light iron thus created would be permanently light, and we should call it another breach of the laws of nature if on lifting it from the water we found it heavy. But if we were to hold a magnet of suitable power over the original heavy iron, when at the bottom of the water, we might see it rise and float, although not touched or upheld by any visible substance, and although its specific gravity remained constant. In this case it would be moved by a power which overcomes gravity, but there would be no creation nor destruction of any property, and no natural law would be broken. But if now we substitute for "magnetic" "Divine" power, there is still no breach of a natural law, for no property is created or destroyed. In both cases the acting agent is a power outside the iron, invisible and unknown, except by the effects. The effect of both is the same: it is to give motion to matter, and nothing more. Hence, neither violate any law of nature except that of inertia.
