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.

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.

Scientia is knowledge. It is only in the popular mind that it is equated with facts.

Science exists, moreover, only as a journey toward troth. Stifle dissent and you end that journey.

Science is an enterprise that can only flourish if it puts the truth ahead of nationality, ethnicity, class and color.

In nation after nation, democracy has taken the place of autocracy.

The eye searches for shapes. It searches for a beginning, a middle, and an end.
