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
People may come along and argue philosophically that they like one better than another but we have learned from much experience that all philosophical intuitions about what nature is going to do fail.
Richard P. Feynman
Today's brains are yesterday's mashed potatoes.
Richard P. Feynman
It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn't get confined, permanently blocked, as it has so many times before in various periods in the history of man.
Richard P. Feynman
People are always asking for the latest developments in the unification of this theory with that theory, and they don't give us a chance to tell them anything about what we know pretty well. They always want to know the things we don't know.
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
Only realistic flight schedules should be proposed, schedules that have a reasonable chance of being met. If in this way the government would not support them, then so be it. NASA owes it to the citizens from whom it asks support to be frank, honest, and informative.
Richard P. Feynman
The first principle is that you must not fool yourself and you are the easiest person to fool.
Richard P. Feynman
Don't think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn't stop you from doing anything at all.
Richard P. Feynman
I'm smart enough to know that I'm dumb.
Richard P. Feynman
I think I can safely say that nobody understands Quantum Mechanics.
Richard P. Feynman
When the problem [quantum chromodynamics] is finally solved, it will all be by imagination. Then there will be some big thing about the great way it was done. But it's simple -it will all be by imagination, and persistence.
Richard P. Feynman
There is one simplification at least. Electrons behave ... in exactly the same way as photons they are both screwy, but in exactly in the same way.
Richard P. Feynman
The real problem in speech is not precise language. The problem is clear language.
Richard P. Feynman
Physicists like to think that all you have to do is say, these are the conditions, now what happens next?
Richard P. Feynman
I have a limited intelligence and I've used it in a particular direction.
Richard P. Feynman
If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.
Richard P. Feynman
There in wine is found the great generalization: all life is fermentation.
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
There are thousands of years in the past, and there is an unknown amount of time in the future. There are all kinds of opportunities, and there are all kinds of dangers.
Richard P. Feynman
To develop working ideas efficiently, I try to fail as fast as I can.
Richard P. Feynman
