Werner Heisenberg Quotes

… theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.

Time plays an important role. My physical body is taking shape in space, and I see that my ideas about how we influence space with our movement is really 'matter of fact.'

It is odd to think that there is a word for something which, strictly speaking, does not exist, namely, "rest." We distinguish between living and dead matter; between moving bodies and bodies at rest. This is a primitive point of view. What seems dead, a stone or the proverbial "door-nail," say, is actually forever in motion. We have merely become accustomed to judge by outward appearances; by the deceptive impressions we get through our senses.

The most loathsome materialism is not the kind people usually think of, but the sort that attempts to let dead ideas pass for living realities, diverting into sterile myths the stubborn and lucid attention we give to what we have within us that must forever die.

In those days it was possible for a Greek to flee from an over-abundant reality as though it were but the tricky scheming off the imagination-and to flee, not like Plato into the land of eternal ideas, into the workshop off the world-creator, feasting one's eyes on the unblemished unbreakable archetypes, but into the rigor mortis off the coldest emptiest concept off all, the concept of being.

The ancient intuition that all matter, all "reality," is energy, that all phenomena, including time and space, are mere crystallizations of mind, is an idea with which few physicists have quarreled since the theory of relativity first called into question the separate identities of energy and matter. Today most scientists would agree with the ancient Hindus that nothing exists or is destroyed, things merely change shape or form; that matter is insubstantial in origin, a temporary aggregate of he pervasive energy that animates the electron.

Time is only an idea. There is only the Reality. Whatever you think it is, it looks like that.

Ideas, unlike solid structures, do not perish. They remain immortal, immaterial and everywhere, like all Divine things. Ideas are a golden, savage landscape that we wander unaware, without a map. Be careful: in the last analysis, reality may be exactly what we think it is.

What a glorious title, Nature, a veritable stroke of genius to have hit upon. It is more than a cosmos, more than a universe. It includes the seen as well as the unseen, the possible as well as the actual, Nature and Nature's God, mind and matter. I am lost in admiration of the effulgent blaze of ideas it calls forth.

There is no place in this new kind of physics both for the field and matter, for the field is the only reality.

I'm the idea of the human imagination, which, when you think about it, is the only thing we can really be certain ISN'T imaginary.

I have spent my life watching, not to see beyond the world, merely to see, great mystery, what is plainly before my eyes. I think the concept of transcendence is based on a misreading of creation. With all respect to heaven, the scene of the miracle is here, among us. The eternal as an idea is much less preposterous than time, and this very fact should seize our attention.

I don't think things are ever exactly the way one expects, and I don't think things are ever the way one assumes they are at the moment. What I actually think is that one has no idea of what things are like, ever.

Steve Grand is the creator of what I think is the nearest approach to artificial life so far, and his first book, Creation: Life and How to Make It, is as interesting as you would expect. But he illuminates more than just the properties of life: his originality extends to matter itself and the very nature of reality. Not since David Deutsch's The Fabric of Reality have I encountered such a compelling invitation to think everything out afresh, from the bottom up.

Everything hangs on one's thinking.

In my mind, I'm doing everything, but in reality, I'm doing very, very little. You come up with one idea, one moment, one line that leads to something and you feel like it's easy. And then, you sit back and think there would be no show without that.

Truth is truth no matter what I think.

But you're dead,' said Harry. 'Oh, yes,' said Dumbledore matter-of-factly. 'Then... am I dead too?' 'Ah,' said Dumbledore, smiling still more broadly. 'That is the question, isn't it? On the whole, dear boy, I think not.

It was a dogma throughout most of the 20th century that quantum science only applied to subatomic matter, and we now know that not to be true. One of the major discoveries was Quantum Holography.

I was pretty far gone, but not so far gone that I thought anyone with half a toehold in reality would think what we were doing was a good idea.

Thinking is the desire to gain reality by means of ideas.

There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time ... On the other hand, I think I can safely say that nobody understands quantum mechanics.

I like shorter jokes. I like fewer words. I think the more ideas there are the, the fewer words there should be.

What we did was to try and exploit that spirit [the idea of giving], which was there even before I approached individual South Africans [to give to the Nelson Mandela Children's Fund]. I think we must start from that angle.

I am not responsible for what other people think. I am responsible only for what I myself think, and I know what that is. No idea I've ever come up with has ever struck me as a divine revelation. Nothing I have ever observed leads me to think there is a God watching over me.
