If the Pentateuch is not inspired in its astronomy, geology, geography, history or philosophy, if it is not inspired concerning slavery, polygamy, war, law, religious or political liberty, or the rights of men, women and children, what is it inspired in, or about? The unity of God?—that was believed long before Moses was born. Special providence?—that has been the doctrine of ignorance in all ages. The rights of property?—theft was always a crime. The sacrifice of animals?—that was a custom thousands of years before a Jew existed. The sacredness of life?—there have always been laws against murder. The wickedness of perjury?—truthfulness has always been a virtue. The beauty of chastity?—the Pentateuch does not teach it. Thou shalt worship no other God?—that has been the burden of all religions.
~ Robert G. Ingersoll
