“The same un-self-conscious honesty that enables a three-year-old to splash joyfully in a rain puddle, or tumble laughing in the grass with a puppy, or point out loudly that you have a booger hanging out of your nose, is what is required to enter heaven. It is the opposite of ignorance—it is intellectual honesty: to be willing to accept reality and to call things what they are even when it is hard.”
