Freeman Dyson

"We have no reason to think that climate change is harmful if you look at the world as a whole. Most places, in fact, are better off being warmer than being colder. And historically, the really bad times for the environment and for people have been the cold periods rather than the warm periods."

"A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering."

"It's better to get mugged than to live a life of fear."

"I have the freedom to do what I want... bright people to talk to every day."

"The purpose of thinking about the future is not to predict it but to raise people's hopes."

"I see a bright future for the biotechnology industry when it follows the path of the computer industry, the path that von Neumann failed to foresee, becoming small and domesticated rather than big and centralized."
