I am neither a saint nor a theologian. To me, good works are more impo — Freeman Dyson

"Science as subversion has a long history. ... Davis and Sakharov belong to an old tradition in science that goes all the way back to the rebels Benjamin Franklin and Joseph Priestley in the eighteenth century, to Galileo and Giordano Bruno in the seventeenth and sixteenth. If science ceases to be a rebellion against authority, then it does not deserve the talents of our brightest children. ... We should try to introduce our children to science today as a rebellion against poverty and ugliness and militarism and economic injustice."

"Trouble arises when either science or religion claims universal jurisdiction, when either religious dogma or scientific dogma claims to be infallible. Religious creationists and scientific materialists are equally dogmatic and insensitive. By their arrogance they bring both science and religion into disrepute. The media exaggerate their numbers and importance. The media rarely mention the fact that the great majority of religious people belong to moderate denominations that treat science with respect, or the fact that the great majority of scientists treat religion with respect so long as religion does not claim jurisdiction over scientific questions."

"It is more difficult for a modern scientist to be a serious Christian, like Polkinghorne, than to be a serious Muslim, like the Nobel Prize-winning physicisit Abdus Salam. Salam happily proclaimed his Muslim faith but did not feel any need to write books about it. For Salam, the idea of a conflict between his faith and his science was ludicrous. Muslim faith has nothing to do with science. But Polkinghorne writes books to prove to himself and to us that his theology and his science can live together harmoniously.."

"It has been generally believed that only the complex numbers could legitimately be used as the ground field in discussing quantum-mechanical operators. Over the complex field, Frobenius theorem is of course not valid; the only division algebra over the complex field is formed by the complex numbers themselves. However, Frobenius theorem is relevant precisely because the appropriate ground field for much of quantum mechanics is real rather than complex."

"It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment."

"I am acutely aware of the fact that the marriage between mathematics and physics, which was so enormously fruitful in past centuries, has recently ended in divorce."

"We have created a wealthy society with tens of millions of talented, resourceful individuals who play virtually no role whatsoever as citizens. Bringing these people in — with their networks of influence, their knowledge, and their resources — is the key to creating the capacity for shared intelligence that we need to solve our problems."

"As in respect of the first wonder we are all on the same level, how comes it that the philosophic mind should, in all ages, be the privilege of a few? The most obvious reason is this: The wonder takes place before the period of reflection, and (with the great mass of mankind) long before the individual is capable of directing his attention freely and consciously to the feeling, or even to its exciting causes. Surprise (the form and dress which the wonder of ignorance usually puts on) is worn away, if not precluded, by custom and familiarity."

"The dualistic philosophy reigned supreme in Europe, dominating the development of Western science. But with the advent of atomic physics, findings based on demonstrable experiment were seen to negate the dualistic theory, and the trend of thought since then has been back to the monistic conception of the ancient Taoists."

"Under the rule of a repressive whole, liberty can be made into a powerful instrument of domination. The range of choice open to the individual is not the decisive factor in determining the degree of human freedom, but what can be chosen and what is chosen by the individual."

"All economic activity is carried out through time. Every individual economic process occupies a certain time, and all linkages between economic processes necessarily involve longer or shorter periods of time."

"I believe that the main lesson which our generation has learnt is that we must find a new limit for the activities of government, a limit which leaves ample scope for sensible experimentation but which secures the freedom of the individual as the mainspring of all social and political activity. The whole purpose of these lectures has been to suggest that we can find such a limit if we are willing to revive and develop the ancient ideal of the Rule of Law."
