“All of the most important questions in life are dismissed most of the time by most of the people, and it is true that much of the world prefers to do something more practical . . . But something happens when you think about these enormous questions. As you imagine, for instance, a chicken emerging from an egg which has emerged from a chicken which has emerged from an egg, your mind wanders as if on a voyage, and as with any voyage, you are likely to discover something along the way.”
