For science must breathe the oxygen of freedom.

Reality is no less precious if it presents itself to someone else. All are discoverers, and if we disenfranchise any, all suffer.

It is folly to use as one's guide in the selection of fundamental science the criterion of utility. Not because (scientists)... despise utility. But because. .. useful outcomes are best identified after the making of discoveries, rather than before.

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.

Instead, in the absence of respect for human rights, science and its offspring technology have been used in this century as brutal instruments for oppression.

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

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