When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the… — Richard P. Feynman Copy Share Image
Doubt is clearly a value in science. It is important to doubt and that the doubt is not a fearful thing, but… — Richard P. Feynman Copy Share Image
You see, one thing is, I can live with doubt and uncertainty and not knowing. I have approximate answers and possible beliefs… — Richard P. Feynman Copy Share Image
We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without… — Richard P. Feynman Copy Share Image
We need to teach how doubt is not to be feared but welcomed. It's OK to say, "I don't know." — Richard P. Feynman Copy Share Image
This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind… — Richard P. Feynman Copy Share Image
It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which… — Richard P. Feynman Copy Share Image
“[Doubt] is not a new idea; this is the idea of the age of reason. This is the philosophy that guided the… — Richard P. Feynman Copy Share Image
There is no harm in doubt and skepticism, for it is through these that new discoveries are made. — Richard P. Feynman Copy Share Image
“You see, one thing is, I can live with doubt and uncertainty and not knowing. I think it's much more interesting to… — Richard P. Feynman Copy Share Image
Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very… — Richard P. Feynman Copy Share Image

A scientist is never certain. ... We absolutely must leave room for doubt or there is no progress and there is no learning. — Richard P. Feynman Copy Share Image
I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of… — Richard P. Feynman Copy Share Image
When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the… — Richard P. Feynman Copy Share Image
Science is a way to teach how something gets to be known, what is not known, to what extent things are known… — Richard P. Feynman Copy Share Image
There is no learning without having to pose a question. And a question requires doubt. — Richard P. Feynman Copy Share Image

“The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I… — Richard P. Feynman Copy Share Image
“Philosophers have said before that one of the fundamental requisites of science is that whenever you set up the same conditions, the same thing… — Richard P. Feynman Copy Share Image
My rule is, when you are unhappy, think about it. But when you're happy, don't. Why spoil it? You're probably happy for some ridiculous… — Richard P. Feynman Copy Share Image
Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic… — Richard P. Feynman Copy Share Image
Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning. — Richard P. Feynman Copy Share Image
It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions. — Richard P. Feynman Copy Share Image
“There was a Princess Somebody of Denmark sitting at a table with a number of people around her, and I saw an empty chair… — Richard P. Feynman Copy Share Image
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 Copy Share Image
“There's a big difference between knowing the name of something and knowing something.” — Richard P. Feynman Copy Share Image
The fact that you are not sure means that it is possible that there is another way someday. — Richard P. Feynman Copy Share Image
One cannot understand... the universality of laws of nature, the relationship of things, without an understanding of mathematics. There is no other way to… — Richard P. Feynman Copy Share Image
