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.

Of all the men that have run for president in the twentieth century, only George McGovern truly understood what a monument America could be to the human race.

The best road to progress is freedom’s road.

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

The Soviet Union, the socialist camp, the People’s Republic of China, and North Korea helped us resist, with essential supplies and weapons, the implacable blockade of the United States, the most powerful empire ever to exist.

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

Despotism can only exist in darkness, and there are too many lights now in the political firmament to permit it to remain anywhere, as it has heretofore done, almost everywhere.

The pursuit of science leads only to the insoluble.

We have no right to express an opinion until we know all of the answers.

America is not nearly done. We’re only in the beginning. Who knows who we will be? Who knows… what color we will be? It is all something that, maybe, our descendants – if they survive that long – will see.

Science is magic that works.

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

Collecting facts is important. Knowledge is important. But if you don’t have an imagination to use the knowledge, civilization is nowhere.

We believe that if men have the talent to invent new machines that put men out of work, they have the talent to put those men back to work.

Africa is on the rise.

Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.

Science is what you know, philosophy is what you don’t know.

Thought must be divided against itself before it can come to any knowledge of itself.

Jurisdictions across the U.S. are snapping up algorithms as tools to help judges make bail and bond decisions. They’re being sold as race- and gender-neutral assessments that allow judges to use science in determining whether someone will behave if released from jail pending trial.

We know the truth, not only by the reason, but also by the heart.

There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.

Science never makes things that do not have to do with what we feel, by which I mean what we want and what we fear.

The more you know the less you need to say.

It is a profound and necessary truth that the deep things in science are not found because they are useful: they are found because it was possible to find them.

Let me tell you what I literally told every world leader I’ve met with, and I’ve met them all: It’s never, never, never been a good bet to bet against America. We have the finest fighting force in the world.

Knowledge rests not upon truth alone, but upon error also.

Time can behave like another direction in space under extreme conditions.

I love trying new things.

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

We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology.

The true university of these days is a collection of books.

Science investigates; religion interprets. Science gives man knowledge which is power; religion gives man wisdom which is control.

The court generally moves in small steps rather than in one giant step.

If I get stuck, I look at a book that tells me how someone else did it. I turn the pages, and then I say, ‚Oh, I forgot that bit,‘ then close the book and carry on. Finally, after you’ve figured out how to do it, you read how they did it and find out how dumb your solution is and how much more clever and efficient theirs is!

The advancement and diffusion of knowledge is the only guardian of true liberty.

When you’re young, you’re very reckless. Then you get conservative. Then you get reckless again.

The person you consider ignorant and insignificant is the one who came from God, that he might learn bliss from grief and knowledge from gloom.

We Americans… bear the ark of liberties of the world.

I’ve learned not to look at reviews. Early on, I did. I was always curious.

We have to abandon the idea that schooling is something restricted to youth. How can it be, in a world where half the things a man knows at 20 are no longer true at 40 – and half the things he knows at 40 hadn’t been discovered when he was 20?

Nevertheless, it is even harder for the average ape to believe that he has descended from man.

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

If one is master of one thing and understands one thing well, one has at the same time, insight into and understanding of many things.

It is a quality of revolutions not to go by old lines or old laws, but to break up both and make new ones.

You always admire what you really don’t understand.

Wisdom is found only in truth.

Music is not math. It’s science. You keep mixing the stuff up until it blows up on you, or it becomes this incredible potion.

Truth is so obscure in these times, and falsehood so established, that, unless we love the truth, we cannot know it.

Even if soccer is not number one in the United States, they do things very well here. There’s much our country can learn from the U.S.A., because we all know that soccer is not the main game in India. We can still do more things, like provide better facilities for the players so they can perform well.

It is possible that mankind is on the threshold of a golden age; but, if so, it will be necessary first to slay the dragon that guards the door, and this dragon is religion.

And while the law of competition may be sometimes hard for the individual, it is best for the race, because it ensures the survival of the fittest in every department.

Washington isn’t a city, it’s an abstraction.

The science of psychology has been far more successful on the negative than on the positive side… It has revealed to us much about man’s shortcomings, his illnesses, his sins, but little about his potentialities, his virtues, his achievable aspirations, or his psychological health.

The ultimate tendency of civilization is towards barbarism.

The only true wisdom is in knowing you know nothing.

Science is but an image of the truth.

The work of science is to substitute facts for appearances, and demonstrations for impressions.

I call upon the scientific community in our country, those who gave us nuclear weapons, to turn their great talents now to the cause of mankind and world peace: to give us the means of rendering these nuclear weapons impotent and obsolete.

ISIS is not an existential threat to something happening to someone in the United States of America. It’s a serious problem overseas, but it’s confusing and frightening.

I was bold in the pursuit of knowledge, never fearing to follow truth and reason to whatever results they led, and bearding every authority which stood in their way.

With Kansas, I had a four-year deal. The initial two months were real tough. I had to adjust a lot. Then, things started looking up.
