We can also profit by reading more modern authors who seem at first sight to be merely perversely questioning what every sensible person knows to be true. Such writers do us a great service, of forcing us to question our old beliefs, so that we may freely and intelligently choose what is sound in them and reject the rest, and thus have our minds prepared for seeing new and unfamiliar truths. Most people do not need protection from being shocked. They need to be shocked a great deal more than they are.
