Mental slavery is mental death, and every man who has given up his intellectual freedom is the living coffin of his dead soul.
Robert Green IngersollSmall 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 IngersollOnly those who live on the labor of the ignorant are the enemies of science. Real love and real religion are in no danger from science. The more we know the safer all good things are.
