In this short address there is no time to speak of other sciences, and to point out the particular evidence furnished by each to establish the dominion of law, nor to more than mention the name of Descartes, the first who undertook to give an explanation of the celestial motions, or who formed the vast and philosophic conception of reducing all the phenomena of the universe to the same law; of Montaigne, one of the heroes of common sense; of Galvani, whose experiments gave the telegraph to the world; of Voltaire, who contributed more than any other of the sons of men to the destruction of religious intolerance; of August Comte, whose genius erected to itself a monument that still touches the stars; of Guttenberg, Watt, Stephenson, Arkwright, all soldiers of science in the grand army of the dead kings. The glory of science is that it is freeing the soul-breaking the mental manacles--getting the brain out of bondage--giving courage to thought--filling the world with mercy, justice and joy. Science found agriculture plowing with a stick--reaping with a sickle--commerce at the mercy of the treacherous waves and the inconstant winds--a world without books--without schools--man denying the authority of reason, employing his ingenuity in the manufacture of instruments of torture--in building inquisitions and cathedrals. It found the land filled with malicious monks--with persecuting Protestants, and the burners of men. It found a world full of fear, ignorance upon its knees; credulity the greatest virtue; women treated like beasts, of burden; cruelty the only means of reformation. It found the world at the mercy of disease and famine; men trying to read their fates in the stars, and to tell their fortunes by signs and wonders; generals thinking to conquer their enemies by making the sign of the cross, or by telling a rosary. It found all history full of petty and ridiculous falsehood, and the Almighty was supposed to spend most of his time turning sticks into snakes, drowning boys for swimming on Sunday, and killing little children for the purpose of converting their parents. It found the earth filled with slaves and tyrants, the people in all countries downtrodden, half naked, half starved, without hope, and without reason in the world. Such was the condition of man when the morning of science dawned upon his brain, and before he had heard the sublime declaration that the universe is governed by law. For the change that has taken place we are indebted solely to science--the only lever capable of raising mankind. Abject faith is barbarism; reason is civilization. To obey is slavish; to act from a sense of obligation perceived by the reason is noble. Ignorance worships mystery; reason explains it--the one grovels, the other soars. No wonder that fable is the enemy of knowledge. A man with a false diamond shuns the society of lapidaries, and it is upon this principle that superstition abhors science.
