You cannot show real respect to your parents by perpetuating their errors.... Do you consider that the inventor of a steel plow cast a slur upon his father who scratched the ground with a wooden one? I do not consider that an invention by the son is a slander upon the father; I regard each invention simply as an improvement; and every father should be exceedingly proud of an ingenious son. If Mr. Talmage has a son, it will be impossible for him to honor his father except by differing with him.
Robert Green IngersollIf abuses are destroyed, man must destroy them. If slaves are freed, man must free them. If new truths are discovered, man must discover them. If the naked are clothed; if the hungry are fed; if justice is done; if labor is rewarded; if superstition is driven from the mind; if the defenseless are protected, and if the right finally triumphs, all must be the work of man. The grand victories of the future must be won by man, and by man alone.
Robert Green IngersollThe ministers, who preached at these revivals, were in earnest. They were zealous and sincere. They were not philosophers. To them science was the name of a vague dread - a dangerous enemy. They did not know much, but they believed a great deal.
Robert Green IngersollWe all know that men in moderate circumstances can have just as comfortable houses as the richest, just as comfortable clothing, just as good food. They can see just as fine paintings, just as marvelous statues, and they can hear just as good music. They can attend the same theaters and the same operas. They can enjoy the same sunshine, and above all, can love and be loved just as well as kings and millionaires.
Robert Green IngersollAll of the Ten Commandments that are good were old; all that were new art foolish. If Jehovah had been civilized he would have left out the commandment about keeping the Sabbath, and in its place would have said: "Thou shalt not enslave thy fellow-men." He would have omitted the one about swearing, and said: "The man shall have but one wife, and the woman but one husband." He would have left out the one about graven images, and in its stead would have said: "Thou shalt not wage wars of extermination, and thou shalt not unsheathe the sword except in self-defence.
Robert Green IngersollThe book, called the Bible, is filled with passages equally horrible, unjust and atrocious. This is the book to be read in schools in order to make our children loving, kind and gentle! This is the book they wish to be recognized in our Constitution as the source of all authority and justice!
