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

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.

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

Human dignity is better served by embracing knowledge.

The applause is a celebration not only of the actors but also of the audience. It constitutes a shared moment of delight.

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.

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.
