Scientific progress on a broad front results from the free play of free intellects, working on subjects of their own choice, in the manner dictated by their curiosity for exploration of the unknown. Freedom of inquiry must be preserved under any plan for Government support of science...

There are no limits to what science can explore.

There must be no barriers to freedom of inquiry … There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. Our political life is also predicated on openness. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress.

In general, scientific progress calls for no more than the absorption and elaboration of new ideas — and this is a call most scientists are happy to heed.

The attempt to discover and promulgate the truth is nevertheless an obligation upon all scientists, one that must be persevered in no matter what the rebuffs—for otherwise what is the point in being a scientist?

Science flourishes best when it uses freely all the tools at hand, unconstrained by preconceived notions of what science ought to be. Every time we introduce a new tool, it always leads to new and unexpected discoveries, because Nature's imagination is richer than ours.

As long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost and science can never regress.

Science should be about the pursuit of truth, and not about the defense of one’s preferred political ideology or personal beliefs.

Science is an ongoing process. It never ends. There is no single ultimate truth to be achieved, after which all the scientists can retire. And because this is so, the world is far more interesting,

The Truth is found when men (and Women) are free to pursue it.

If we value the pursuit of knowledge, we must be free to follow wherever that search may lead us. The free mind is no barking dog to be tethered on a ten-foot chain.

Science is an ongoing process. It never ends. There is no single ultimate truth to be achieved, after which all the scientists can retire.

Advances in science when put to practical use mean more jobs, higher wages, shorter hours, more abundant crops, more leisure for recreation, for study, for learning how to live without the deadening drudgery which has been the burden of the common man for ages past. Advances in science will also bring higher standards of living, will lead to the prevention or cure of diseases, will promote conservation of our limited national resources, and will assure means of defense against aggression. But to achieve these objectives — to secure a high level of employment, to maintain a position of world leadership — the flow of new scientific knowledge must be both continuous and substantial.

We are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it.
