If the account given in Genesis is really true, ought we not, after all, to thank this serpent? He was the first schoolmaster, the first advocate of learning, the first enemy of ignorance, the first to whisper in human ears the sacred word liberty, the creator of ambition, the author of modesty, of inquiry, of doubt, of investigation, of progress and of civilization.
Robert Green IngersollYou 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.
