There’s no tragedy in life like the death of a child. Things never get back to the way they were.

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.

Of all the things which wisdom provides to make us entirely happy, much the greatest is the possession of friendship.

When it’s your time, it is your time.

Europe is so well gardened that it resembles a work of art, a scientific theory, a neat metaphysical system. Man has re-created Europe in his own image.

A person who won’t read has no advantage over one who can’t read.

I don’t see the wisdom in modern politicians that I once saw in men like Dean Acheson, David Bruce, or George Marshall. In my day, the northeastern establishment dominated foreign policy formulation, but the composition and distribution of our population is very different today.

New knowledge is the most valuable commodity on earth. The more truth we have to work with, the richer we become.

The invariable mark of wisdom is to see the miraculous in the common.

Science has explained nothing; the more we know the more fantastic the world becomes and the profounder the surrounding darkness.

I don’t think that faith, whatever you’re being faithful about, really can be scientifically explained. And I don’t want to explain this whole life business through truth, science. There’s so much mystery. There’s so much awe.

My grandfather was smart and had a whole lot of pride. He didn’t speak a terrible amount, but you could tell there was a ton on his mind – like a quiet acceptance of how life had turned out.

Nature is not human hearted.

How do you know what it’s like to be stupid if you’ve never been smart?

It is best to rise from life as from a banquet, neither thirsty nor drunken.

He that hath knowledge spareth his words.

Any fool can criticize, condemn and complain – and most fools do.

In order for the United States to do the right things for the long term, it appears to be helpful for us to have the prospect of humiliation. Sputnik helped us fund good science – really good science: the semiconductor came out of it.

Baseball is a universe as large as life itself, and therefore all things in life, whether good or bad, whether tragic or comic, fall within its domain.

At eighteen our convictions are hills from which we look; at forty-five they are caves in which we hide.

Life has no meaning the moment you lose the illusion of being eternal.

Our lifelong certainties about the world can be demolished in a single second.

To enjoy good health, to bring true happiness to one’s family, to bring peace to all, one must first discipline and control one’s own mind. If a man can control his mind he can find the way to Enlightenment, and all wisdom and virtue will naturally come to him.

We humans have lost the wisdom of genuinely resting and relaxing. We worry too much. We don’t allow our bodies to heal, and we don’t allow our minds and hearts to heal.

My preparation is about precision. It is a science.

If my life was a movie, no one would believe it.

To learn something but not to do is really not to learn. To know something but not to do is really not to know.

Those who have knowledge, don’t predict. Those who predict, don’t have knowledge.

The truth is incontrovertible. Malice may attack it, ignorance may deride it, but in the end, there it is.

I still live, I still think: I still have to live, for I still have to think.

Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It’s really counterintuitive.

While I thought that I was learning how to live, I have been learning how to die.

Life would be tolerable but for its amusements.

A lie gets halfway around the world before the truth has a chance to get its pants on.

No face which we can give to a matter will stead us so well at last as the truth. This alone wears well.

Science is global. Einstein’s equation, E=mc2, has to reach everywhere. Science is a beautiful gift to humanity, we should not distort it. Science does not differentiate between multiple races.

Life is thickly sown with thorns, and I know no other remedy than to pass quickly through them. The longer we dwell on our misfortunes, the greater is their power to harm us.

I draw pleasure in governance, in doing new things and bringing people together. That pleasure is all I need from life.

I have rooms full of little dongly things and don’t want any more. Half the little dongly things I’ve got, I don’t even know what gizmo they’re for. More importantly, half the gizmos I’ve got, I don’t know where their little dongly thing is.

I think there is only one quality worse than hardness of heart and that is softness of head.

If you hold a cat by the tail you learn things you cannot learn any other way.

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

In order to speak about all and to all, one has to speak of what all know and of the reality common to us all. The sea, rains, necessity, desire, the struggle against death… these are things that unite us all.

There is only one thing in life worse than being talked about, and that is not being talked about.

If God treats you well by teaching you a disastrous lesson, you never forget it.

Even a happy life cannot be without a measure of darkness, and the word happy would lose its meaning if it were not balanced by sadness. It is far better take things as they come along with patience and equanimity.
