In chemistry the war was long and bitter; but we now no longer seek for the elixir of life, and no one is trying to find the philosopher's stone. We are satisfied that there is nothing supernatural in all the realm of chemistry. We know that substances are always true to their natures; we know that just so many atoms of one substance will unite with just so many of another. The miraculous has departed from chemistry; in that science there is no magic, no caprice and no possible use for the supernatural. We are satisfied that there can be no change, that we can absolutely rely on the uniformity of nature; that the attraction of gravitation will always remain the same; and we feel that we know this as certainly as we know that the relation between the diameter and circumference of a circle can never change. We now know that in mechanics the natural is supreme. We know that man can by no possibility create a force; that by no possibility can he destroy a force. No mechanic dreams of depending upon or asking for any supernatural aid. He knows that he works in accordance with certain facts that no power can change. So we in the United States believe that the authority to govern, the authority to make and execute laws, comes from the consent of the governed and not from any supernatural source. We do not believe that the king occupied his throne because of the will of the supernatural. Neither do we believe that others are subjects or serfs or slaves by reason of any supernatural will. So, our ideas of morality have changed, and millions now believe that whatever produces happiness and well-being is in the highest sense moral. Unreasoning obedience is not the foundation or the essence of morality. That is the result of mental slavery. To act in accordance with obligation perceived is to be free and noble. To simply obey is to practice what might be called a slave virtue; but real morality is the flower and fruit of liberty and wisdom. There are very many who have reached the conclusion that the supernatural has nothing to do with real religion. Religion does not consist in believing without evidence or against evidence. It does not consist in worshiping the unknown or in trying to do something for the Infinite. Ceremonies, prayers and inspired books, miracles, special providence, and divine interference all belong to the supernatural and form no part of real religion. Every science rests on the natural, on demonstrated facts. So, morality and religion must find their foundations in the necessary nature of things. II. HOW CAN WE REFORM THE WORLD?
