When, as we must often do, we fear science, we really fear ourselves. Human dignity is better served by embracing knowledge.

Even in the world of molecules the civilising influence of modest restraints is a cause for rejoicing.

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

Nothing is more irredeemably irrelevant than bad science.

Human dignity is better served by embracing knowledge.

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.

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.
