Small people delight in what they call consistency-that is, it gives them immense pleasure to say that they believe now exactly as they did ten years ago. This simply amounts to a certificate that they have not grown-that they have not developed-and that they know just as little now as they ever did. The highest possible conception of consistency is to be true to the knowledge of today, without the slightest reference to what your opinion was years ago.
Robert Green IngersollTo avoid pain we must know the conditions of health. For the accomplishment of this end we must rely upon investigation instead of faith, upon labor in place of prayer. Most misery is produced by ignorance. Passions sow the seeds of pain.
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.
