“My objection to fundamentalism is not that they are fundamentalists but that essentially they want me to be a fundamentalist, too. Now, they may say that I believe evolution is true and I want everyone to believe that evolution is true. But I don’t want everyone to believe that evolution is true, I want them to study what we say about evolution and to decide for themselves. Fundamentalists say they want to treat creationism on an equal basis. But they can’t. It’s not a science. You can teach creationism in churches and in courses on religion. They would be horrified if I were to suggest that in churches they should teach secular humanism as an alternate way of looking at the universe or evolution as an alternate way of considering how life may have started. In the church they teach only what they believe, and rightly so, I suppose. But on the other hand, in schools, in science courses, we’ve got to teach what scientists think is the way the universe works.”

“People think of education as something that they can finish. And what’s more, when they finish, it’s a rite of passage. You’re finished with school. You’re no more a child, and therefore anything that reminds you of school - reading books, having ideas, asking questions - that’s kid’s stuff. Now you’re an adult, you don’t do that sort of thing any more.

You have everybody looking forward to no longer learning, and you make them ashamed afterward of going back to learning. If you have a system of education using computers, then anyone, any age, can learn by himself, can continue to be interested. If you enjoy learning, there’s no reason why you should stop at a given age. People don’t stop things they enjoy doing just because they reach a certain age.

What’s exciting is the actual process of broadening yourself, of knowing there’s now a little extra facet of the universe you know about and can think about and can understand. It seems to me that when it’s time to die, there would be a certain pleasure in thinking that you had utilized your life well, learned as much as you could, gathered in as much as possible of the universe, and enjoyed it. There’s only this one universe and only this one lifetime to try to grasp it. And while it is inconceivable that anyone can grasp more than a tiny portion of it, at least you can do that much. What a tragedy just to pass through and get nothing out of it.”

"There are no nations! There is only humanity. And if we don't come to understand that right soon, there will be no nations, because there will be no humanity."

"Never let your sense of morals get in the way of doing what's right."

"To succeed, planning alone is insufficient. One must improvise as well."

"There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'My ignorance is just as good as your knowledge.'"
