Our civilization is not Christian. It does not come from the skies. It is not a result of inspiration. It is the child of invention, of discovery, of applied knowledge - that is to say, of science. When man becomes great and grand enough to admit that all have equal rights; when thought is untrammeled; when worship shall consist in doing useful things; when religion means the discharge of obligations to our fellow-men, then, and not until then, will the world be civilized.
Robert Green IngersollAt thirty most men have prejudices rather than opinions-that is to say, rather than judgments-and few men have lived to be sixty without materially modifying the opinions they held at thirty.
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.
Robert Green IngersollThe old man has been long at the fair. He is acquainted with the jugglers at the booths. His curiosity has been satisfied. He no longer cares for the exceptional, the monstrous, the marvelous and deformed. He looks through and beyond the gilding, the glitter and gloss, not only of things, but of conduct, of manners, theories, religions and philosophies. He sees clearer. The light no longer shines in his eyes.
Robert Green IngersollSome president wishes to be re-elected, and thereupon speaks about the Bible as "the corner-stone of American Liberty." This sentence is a mouth large enough to swallow any church, and from that time forward the religious people will be citing that remark of the politician to substantiate the inspiration of the Scriptures.
