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

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.

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.

Human dignity is better served by embracing knowledge.

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

The respect for human rights, essential if we are to use technology wisely, is not something alien that must be grafted onto science. On the contrary, it is integral to science, as also to scholarship in general.

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