“I'm more interested in arousing enthusiasm in kids than in teaching the facts. The facts may change, but that enthusiasm for exploring the world will remain with them the rest of their lives.”

“Knowledge empowers people with our most powerful tool: the ability to think and decide. There is no power for change greater than a child discovering what he or she cares about. (Speech about Global Warming read on the National Mall for the 40th anniversary of Earth Day, 2010)”

“We all have beliefs and expectations from our personal experience; it is impossible to live without them. Since we have to make some assumptions, they might as well be ones that allow us freedom, choice and fun in the world, rather than ones that limit us. You often get what you expect to get.”

“Words are anchors for sense experience, but the experience is not the reality, and the word is not the experience. Language is thus two removes from reality. To argue about the real meaning of a word is rather like arguing that one menu tastes better than another because you prefer the food that is printed on it...To come to believe that the external world is patterned by the way we talk about it is even worse than eating the menu - it is eating the printing ink on the menu. Words can be combined and manipulated in ways that have nothing to do with sensory experience.”

“Why' questions have little value, at best they get justifications or long explanations which do nothing to change the situation.”

“Every maker of video games knows something that the makers of curriculum don't seem to understand. You'll never see a video game being advertised as being easy. Kids who do not like school will tell you it's not because it's too hard. It's because it's--boring”

“What happens to our thoughts as we clothe them in language, and how faithfully are they preserved when our listeners undress them?”
