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

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

Individual scientists like myself - and many more conspicuous - pointed to the dangers of radioactive fallout over Canada if we were to launch nuclear weapons to intercept incoming bombers.

Though we explore in a culturally-conditioned way, the reality we sketch is universal.

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.

It takes a trained and discerning researcher to keep the goal in sight, and to detect evidence of the creeping progress toward it.

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.
