“When you think of it, really there are four fundamental questions of life. You've asked them, I've asked them, every thinking person asks them. They boil down to this; origin, meaning, morality and destiny. 'How did I come into being? What brings life meaning? How do I know right from wrong? Where am I headed after I die?'”
