We absolutely must leave room for doubt or there is no progress and no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty.
Richard P. Feynman

More quotes by Richard P. Feynman
Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question - to doubt - to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.
Richard P. Feynman
Start out understanding religion by saying everything is possibly wrong... As soon as you do that, you start sliding down an edge which is hard to recover from.
Richard P. Feynman
Nature...cannot be fooled!
Richard P. Feynman
The electron is a theory. But the theory is so good we can almost consider them real.
Richard P. Feynman
Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.
Richard P. Feynman
The scale of light can be described by numbers called the frequency and as the numbers get higher, the light goes from red to blue to ultraviolet. We can't see ultraviolet light, but it can affect photographic plates. It's still light only the number is different.
Richard P. Feynman
It requires a much higher degree of imagination to understand the electromagnetic field than to understand invisible angels. ... I speak of the E and B fields and wave my arms and you may imagine that I can see them ... [but] I cannot really make a picture that is even nearly like the true waves.
Richard P. Feynman
People who wish to analyze nature without using mathematics must settle for a reduced understanding.
Richard P. Feynman
You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no real problem. It has not yet become obvious to me that there's no real problem. I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem.
Richard P. Feynman
To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature ... If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.
Richard P. Feynman
The unanswerable mysteries... the attitude that all is uncertain... to summarize it - the humility of the intellect.
Richard P. Feynman
Computer science is not as old as physics it lags by a couple of hundred years. However, this does not mean that there is significantly less on the computer scientist's plate than on the physicist's: younger it may be, but it has had a far more intense upbringing!
Richard P. Feynman
We scientists are clever — too clever — are you not satisfied? Is four square miles in one bomb not enough? Men are still thinking. Just tell us how big you want it!
Richard P. Feynman
I wonder why. I wonder why. I wonder why I wonder.
Richard P. Feynman
Philosophers say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong.
Richard P. Feynman
We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation.
Richard P. Feynman
If you don't like it, go somewhere else, to another universe where the rules are simpler.
Richard P. Feynman
All the time you're saying to yourself, 'I could do that, but I won't,'--which is just another way of saying that you can't.
Richard P. Feynman
This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind which the student must first acquire. It becomes a habit of thought. Once acquired, we cannot retreat from it anymore.
Richard P. Feynman
There in wine is found the great generalization: all life is fermentation.
Richard P. Feynman
