The geology of the Bible--of the "divinely inspired" church, of the "infallible" pope, was found to be utterly false and foolish. The Earth became a witness against the creeds of superstition. Then came Watt and Galvani with the miracles of steam and electricity, while countless inventors created the wonderful machines that do the work of the world. Investigation took the place of credulity. Men became dissatisfied with huts and rags, with crusts and creeds. They longed for the comforts, the luxuries of life. The intellectual horizon enlarged, new truths were discovered, old ideas were thrown aside, the brain was developed, the heart civilized and science was born. Humboldt, Laplace and hundreds of others explained the phenomena of nature, called attention to the ancient and venerable mistakes of sanctified ignorance and added to the sum of knowledge. Darwin and Haeckel gave their conclusions to the world. Men began to really think, the myths began to fade, the miracles to grow mean and small, and the great structure, known as theology, fell with a crash. Science denies the truth of myth and miracle, denies that human testimony can substantiate the miraculous, denies the existence of the supernatural. Science asserts the absolute, the unvarying uniformity of nature. Science insists that the present is the child of all the past,--that no power can change the past, and that nature is forever the same. The chemist has found that just so many atoms of one kind unite with just so many of another--no more, no less, always the same. No caprice in chemistry; no interference from without. The astronomers know that the planets remain in their orbits--that their forces are constant. They know that light is forever the same, always obeying the angle of incidence, traveling with the same rapidity,--casting the same shadow, under the same circumstances in all worlds. They know that the eclipses will occur at the times foretold--neither hastening nor delaying. They know that the attraction of gravitation is always the same, always in perfect proportion to mass and distance, neither weaker nor stronger, unvarying forever. They know that the facts in nature cannot be changed or destroyed, and that the qualities of all things are eternal. The men of science know that the atomic integrity of the metals is always the same, that each metal is true to its nature and that the particles cling to each other with the same tenacity,--the same force. They have demonstrated the persistence of force, that it is forever active, forever the same, and that it cannot be destroyed. These great truths have revolutionized the thought of the world. Every art, every employment, all study, all experiment, the value of experience, of judgment, of hope, all rest on a belief in the uniformity of nature, on the eternal persistence and indestructibility of force.
