Each second we live is a new and unique moment of the universe, a moment that will never be again. And what do we teach our children in school? We teach them that two and two make four and that Paris is the capital of France. When will we also teach them what they are? We should say to them: Do you know what you are? You are a marvel. You are unique. In all the years that have passed, there has never been another child like you. And look at your body — what a wonder it is! Your legs, your arms, your clever fingers, the ways you move. You may become a Shakespeare, a Michelangelo, a Beethoven. You have the capacity for anything. Yes, you are a marvel. And when you grow up, can you then harm another who is, like you, a marvel? You must work — we must all work — to make the world worthy of its children.
