When, as we must often do, we fear science, we really fear ourselves. Human dignity is better served by embracing knowledge.

Young people ask me if this country is serious about science. They aren't thinking about the passport that they will hold, but the country that they must rely on for support and encouragement.

Idealism is the highest form of reason.

Though we explore in a culturally-conditioned way, the reality we sketch is universal.

Discoveries that are anticipated are seldom the most valuable. ... It's the scientist free to pilot his vessel across hidden shoals into open seas who gives the best value.

Some dreamers demand that scientists only discover things that can be used for good.

Reality is no less precious if it presents itself to someone else. All are discoverers, and if we disenfranchise any, all suffer.
