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.

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.

A new sense of shared international responsibility is unmistakable in the voices of the United Nations and its agencies, and in the civil society of thousands of supra-national NGOs.

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.

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

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

Science is a collection of stories, linking characters worthy of notice.
