That’s why the English essayist William Hazlitt wrote, “Without the aid of prejudice and custom, I should not be able to find my way across the room; nor know how to conduct myself in any circumstances, nor what to feel in any relation of life. Reason may play the critic, and correct certain errors afterwards; but if we were to wait for its formal and absolute decisions in the shifting and multifarious combinations of human affairs, the world would stand still.”
