I knew, however, that it would cost ten times what I had available in order to build a molecular beam machine. I decided to follow a byway, rather than the highway. It is a procedure I have subsequently recommended to beginning scientists in this country, where research strategy is best modelled on that used by Wolfe at the Plains of Abraham.

Idealism is the highest form of reason.

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

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.

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.

At the heart of science lies discovery which involves a change in worldview. Discovery in science is possible only in societies which accord their citizens the freedom to pursue the truth where it may lead and which therefore have respect for different paths to that truth.
