We find that the statements of science are not of what is true and what is not true, but statements of what is known with different degrees of certainty: It is very much more likely that so and so is true than that it is not true.
Richard P. Feynman

More quotes by Richard P. Feynman
It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we can discuss.
Richard P. Feynman
If you think you understand quantum mechanics, you don't understand quantum mechanics.
Richard P. Feynman
There are all kinds of interesting questions that come from a knowledge of science, which only adds to the excitement and mystery and awe of a flower.
Richard P. Feynman
I don't feel frightened by not knowing things.
Richard P. Feynman
Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.
Richard P. Feynman
It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.
Richard P. Feynman
I don't know what's the matter with people: they don't learn by understanding, they learn by some other way — by rote or something. Their knowledge is so fragile!
Richard P. Feynman
If I say [electrons] behave like particles I give the wrong impression also if I say they behave like waves. They behave in their own inimitable way, which technically could be called a quantum mechanical way. They behave in a way that is like nothing that you have seen before.
Richard P. Feynman
The first principle is that you must not fool yourself and you are the easiest person to fool.
Richard P. Feynman
What we need is imagination, but imagination in a terrible strait-jacket.
Richard P. Feynman
By honest I don't mean that you only tell what's true. But you make clear the entire situation. You make clear all the information that is required for somebody else who is intelligent to make up their mind.
Richard P. Feynman
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
The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?
Richard P. Feynman
If you don't like it, go somewhere else, to another universe where the rules are simpler.
Richard P. Feynman
We have this terrible struggle to try to explain things to people who have no reason to want to know.
Richard P. Feynman
Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
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
I love only nature, and I hate mathematicians.
Richard P. Feynman
In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth.
Richard P. Feynman
What Do You Care What Other People Think?
