I have had dreams and I have had nightmares, but I have conquered my nightmares because of my dreams
Life is an error-making and an error-correcting process, and nature in marking man's papers will grade him for wisdom as measured both by survival and by the quality of life of those who survive.
Our greatest responsibility is to be good ancestors
There is hope in dreams, imagination, and in the courage of those who wish to make those dreams a reality.
Edward R. Murrow: Who owns the patent on this vaccine? Jonas Salk: Well, the people, I would say. There is no patent. Could you patent the sun?
Some people are constructive, if you like. Others are destructive. It's this diversity in humankind that results in some making positive contributions and some negative contributions. It's necessary to have enough who make positive contributions to overcome the problems of each age.

You have to develop a thick skin in life. Its not in this field only. You might think of the ideal of the scientists, the ivory tower, the idealist. That's true of some. And I wouldn't guess as to what proportion. But there are some who are of that character, and there are some who are not.
There are three stages of truth. First is that it can't be true, and that's what they said. You couldn't immunize against polio with a killed-virus vaccine. Second phase: they say, Well, if it's true, it's not very important. And the third stage is, 'Well, we've known it all along.
