A scientist should be the happiest of men.

I tell my students to try early in life to find an unattainable objective.

You see, every creature alive on the earth today represents an unbroken line of life that stretches back to the first primitive organism to appear on this planet; and that is about three billion years.

The Vietnamese have a secret weapon. It's their willingness to die beyond our willingness to kill. In effect, they've been saying, You can kill us, but you'll have to kill a lot of us; you may have to kill all of us. And, thank heaven, we are not yet ready to do that.

The thought that we're in competition with Russians or with Chinese is all a mistake, and trivial. We are one species, with a world to win.

It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom's way of knowing about atoms.

We are the products of editing, rather than of authorship.

To know reality is to accept it, and eventually to love it.

We have to get rid of those nuclear weapons.

I am growing old, and my future, so to speak, is already behind me.

Science goes from question to question; big questions, and little, tentative answers. The questions as they age grow ever broader, the answers are seen to be more limited.

We've committed many war crimes in Vietnam - but I'll tell you something interesting about that. We were committing war crimes in World War II, before the Nuremberg trials were held and the principle of war crimes was stated.

So-called defense now absorbs sixty per cent of the national budget, and about twelve per cent of the Gross National Product.

I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule?

As you lecture, you keep watching the faces, and information keeps coming back to you all the time.

Nuclear weapons offer us nothing but a balance of terror, and a balance of terror is still terror.

A scientist should be the happiest of men.

There is nothing worth having that can he obtained by nuclear war - nothing material or ideological - no tradition that it can defend. It is utterly self-defeating.

The Nobel Prize is an honor unique in the world in having found its way into the hearts and minds of simple people everywhere. It casts a light of peace and reason upon us all; and for that I am especially grateful.

A lecture is much more of a dialogue than many of you probably realize.

I think all of you know there is no adequate defense against massive nuclear attack.

In fact, death seems to have been a rather late invention in evolution. One can go a long way in evolution before encountering an authentic corpse.

A scientist lives with all reality. There is nothing better.

The only use for an atomic bomb is to keep somebody else from using one.

The only point of government is to safeguard and foster life.

Dropping those atomic bombs on Hiroshima and Nagasaki was a war crime.

We have fallen in love with the body. That's that thing that looks back at us from the mirror. That's the repository of that lovely identity that you keep chasing all your life.

Our business is with life, not death.

All War Departments are now Defense Departments. This is all part of the doubletalk of our time. The aggressor is always on the other side.

There's life all over this universe, but the only life in the solar system is on earth, and in the whole universe we are the only men.

The trouble with most of the things that people want is that they get them.

I have lived much of my life among molecules. They are good company.

As far as I know, the most conservative estimates of the number of Americans who would be killed in a major nuclear attack, with everything working as well as can be hoped and all foreseeable precautions taken, run to about fifty million.

Since we have had a history, men have pursued an ideal of immortality.

And, you see, we are living in a world in which all wars are wars of defense.

It's not good enough to give it tender, loving care, to supply it with breakfast foods, to buy it expensive educations. Those things don't mean anything unless this generation has a future. And we're not sure that it does.

A physicist is an atom's way of knowing about atoms.

A scientist is in a sense a learned small boy. There is something of the scientist in every small boy. Others must outgrow it. Scientists can stay that way all their lives.

A peacetime draft is the most un-American thing I know.

The concept of war crimes is an American invention.

There is nothing worth having that can be obtained by nuclear war - nothing material or ideological - no tradition that it can defend. It is utterly self-defeating.

Most modern biologists, having reviewed with satisfaction the downfall of the spontaneous generation hypothesis, yet unwilling to accept the alternative belief in special creation, are left with nothing.

The Vietnamese have a secret weapon. It's their willingness to die beyond our willingness to kill. In effect, they've been saying, you can kill us, but you'll have to kill a lot of us; You may have to kill all of us. And, thank heaven, we are not yet ready to do that.

The woman who thinks she is intelligent demands equal rights with men. A woman who is intelligent does not.

If it weren't for women, men would still be wearing last week's socks.

All literary men are Red Sox fans - to be a Yankee fan in a literate society is to endanger your life.

It is chiefly through books that we enjoy intercourse with superior minds. In the best books, great men talk to us, give us their most precious thoughts, and pour their souls into ours.

Men live by intervals of reason under the sovereignty of humor and passion.

To a smart girl men are no problem - they're the answer.
