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.

Science never gives up searching for truth, since it never claims to have achieved it.

[Intellectual courage is] the quality that allows one to believe in one's judgement in the face of disappointment and widespread skepticism. Intellectual courage is even rarer than physical courage.

Today, Academies of Science use their influence around the world in support of human rights.

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.

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

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.
