The first step is for man to cease to be the slave of man. The second, is to cease to be the slave of the monsters of his own creation, the ghosts and phantoms of the air.
Robert Green IngersollA man is not moral because he is obedient through fear or ignorance. Morality lives in the realm of perceived obligation.
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 IngersollEvery church pretends to have found the exact truth. This is the end of progress. Why pursue that which you have? Why investigate when you know? Every creed is a rock in running water: humanity sweeps by it. Every creed cries to the universe, "Halt!" A creed is the ignorant Past bullying the enlightened Present. The ignorant are not satisfied with what can be demonstrated. Science is too slow for them, and so they invent creeds. They demand completeness. A sublime segment, a grand fragment, are of no value to them. They demand the complete circle... the entire structure.
Robert Green IngersollWhen a fact can be demonstrated, force is unnecessary; when it cannot be demonstrated, force is infamous.
Robert Green IngersollWhy should we desire the destruction of human passions? Take passions from human beings and what is left? The great object should be not to destroy passions, but to make them obedient to the intellect. To indulge passion to the utmost is one form of intemperance - to destroy passion is another. The reasonable gratification of passion under the domination of the intellect is true wisdom and perfect virtue.
