"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those that tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious who comes ambling along."
