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.

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

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.

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

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.

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.
