The American doctor, in my opinion, possesses a combination of conservatism and that other quality which has put the United States in the forefront in almost every department of science – that is, an eagerness to know what it is really all about in order that he may not be the one left behind if there is something to it.

The most obvious characteristic of science is its application: the fact that, as a consequence of science, one has a power to do things. And the effect this power has had need hardly be mentioned. The whole industrial revolution would almost have been impossible without the development of science.

In many respects, the United States is a great country. Freedom of speech is protected more than in any other country. It is also a very free society.

Seeing much, suffering much, and studying much, are the three pillars of learning.

Self-government does not and should not imply the use of political agencies alone. Progress is born of cooperation in the community – not from governmental restraints.

Science is a wonderful thing if one does not have to earn one’s living at it.

To penetrate and dissipate these clouds of darkness, the general mind must be strengthened by education.

A person who is too nice an observer of the business of the crowd, like one who is too curious in observing the labor of bees, will often be stung for his curiosity.

One of the very important characteristics of a student is to question. Let the students ask questions.

I remain convinced that obstinate addiction to ordinary language in our private thoughts is one of the main obstacles to progress in philosophy.

It’s OK for China to invent cancer drugs that cure patients in the United States. We want them to catch up. But as the leader, we want to keep setting a very, very high standard. We don’t want them to catch up because we’re slowing down or, even worse, going into reverse.

Politics is a science. You can demonstrate that you are right and that others are wrong.

In the history of medicine, it is not always the great scientist or the learned doctor who goes forward to discover new fields, new avenues, new ideas.

I never see what has been done; I only see what remains to be done.

Of course humans like to explore, and we should. There’s nothing wrong with that. But it’s more than that. It’s essential for your children and your children’s children.

Actually oddly enough, I think my work, the activism, will be forgotten. And I hope it will. Because I hope those problems will have gone away.

Knowledge will forever govern ignorance; and a people who mean to be their own governors must arm themselves with the power which knowledge gives.

Illinois surpasses every other spot of equal extent upon the face of the globe in fertility of soil and in the proportionable amount of the same which is sufficiently level for actual cultivation.

Develop an attitude of gratitude, and give thanks for everything that happens to you, knowing that every step forward is a step toward achieving something bigger and better than your current situation.

I feel like the thing we can do is celebrate people doing great work and create more cultural momentum and awareness that this is an important thing in the world. So when the next economic crisis hits and people are talking about where to cut from the budget, science isn’t the thing.

Knowledge is power.

I am a part of everything that I have read.

I sincerely hope I can contribute to the progress there has been in relations between Jews and Catholics since the Second Vatican Council in a spirit of renewed collaboration.

I have hardly ever known a mathematician who was capable of reasoning.

Eradications are special. Zero is a magic number. You either do what it takes to get to zero and you’re glad you did it; or you get close, give up and it goes back to where it was before, in which case you wasted all that credibility, activity, money that could have been applied to other things.

I’ve always been amazed by Da Vinci, because he worked out science on his own. He would work by drawing things and writing down his ideas. Of course, he designed all sorts of flying machines way before you could actually build something like that.

Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to, and it appears peculiar and mysterious to everyone – both to the novice and to the experienced physicist.

The fact is: It’s true what they say about the United States. It is a land of opportunity. It is too various to get bored with it.

So while an incredible amount of progress has been made, on this fifth anniversary, I wanted to come here and tell the people of this city directly: My administration is going to stand with you – and fight alongside you – until the job is done. Until New Orleans is all the way back, all the way.

I grow daily to honour facts more and more, and theory less and less. A fact, it seems to me, is a great thing; a sentence printed, if not by God, then at least by the Devil.

If we knew what it was we were doing, it would not be called research, would it?

Real knowledge is to know the extent of one’s ignorance.

Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity.

The United States fully accepts the profound truth that our own progress, prosperity, and peace are interlocked with the progress, prosperity, and peace of all humanity.

I had no talent for science. What was infinitely worse: all my fraternity brothers were engineers.

In the United States, one of the main topics of academic political science is the study of attitudes and policy and their correlation. The study of attitudes is reasonably easy in the United States: heavily-polled society, pretty serious and accurate polls, and policy you can see, and you can compare them.

I think America has always been polarized.

The point in history at which we stand is full of promise and danger. The world will either move forward toward unity and widely shared prosperity – or it will move apart.

Chinese military spending is carefully monitored by the United States.

Nature knows no pause in progress and development, and attaches her curse on all inaction.

The only real security that a man can have in this world is a reserve of knowledge, experience and ability.

Knowledge will give you power, but character respect.

The progress of India is the destiny of one-sixth of humanity. And it will also mean a world more confident of its prosperity and more secure about its future.

If the national mental illness of the United States is megalomania, that of Canada is paranoid schizophrenia.

I’m never going to go to Mars, but I’ve helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

While some doubted that connecting the world was actually important, we were building. While others doubted that this would be sustainable, you were forming lasting connections. We just cared more about connecting the world than anyone else. And we still do today.

I am the wisest man alive, for I know one thing, and that is that I know nothing.

A jug fills drop by drop.

Therefore, the good of man must be the end of the science of politics.

The United States is definitely ahead in culture of innovation. If someone wants to accomplish great things, there is no better place than the U.S.

Up until the 1920s, everyone thought the universe was essentially static and unchanging in time.

As a nuclear power – as the only nuclear power to have used a nuclear weapon – the United States has a moral responsibility to act.

Women have to be active listeners and interrupters – but when you interrupt, you have to know what you are talking about.

The best road to progress is freedom’s road.

We must accept what science tells us, that man was born from the earth. But, more logical than the scientists who lecture us, we must carry this lesson to its conclusion: that is to say, accept that man was born entirely from the world – not only his flesh and bones but his incredible power of thought.

I feel good because I believe I have made progress in rebuilding the people’s trust in their government.

Knowledge which is acquired under compulsion obtains no hold on the mind.

There’s very little advice in men’s magazines, because men don’t think there’s a lot they don’t know. Women do. Women want to learn. Men think, ‚I know what I’m doing, just show me somebody naked.‘

There is nothing new in the world except the history you do not know.

If money is your hope for independence you will never have it. The only real security that a man will have in this world is a reserve of knowledge, experience, and ability.

Surely the wake left behind by mankind’s forward march reveals its movement just as clearly as the spray thrown up elsewhere by the prow.
