Famous Quotes & Sayings

Richard P. Feynman

I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.

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 odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.

Richard P. Feynman

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

Richard P. Feynman

Scientists are explorers. Philosophers are tourists.

Richard P. Feynman

The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. ... If you will simply admit that maybe [Nature] does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that.

Richard P. Feynman

If you thought that science was certain - well, that is just an error on your part.

Richard Dawkins

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.

Richard Whately

To teach one who has no curiosity to learn, is to sow a field without ploughing it.

Peter Roebuck

It can be absurd, cantankerous, self-destructive and pompous, but it is never crass

Richard Paul Evans

In your hurry to keep Christmas, you have forgotten Christmas. The truest gift of Christmas is the gift of self.

Richard Dawkins

It often turns out on closer inspection that acts of apparent altruism are really selfishness in disguise.

Richard Dawkins

We, alone on earth, can rebel against the tyranny of the selfish replicators.

Richard Dawkins

Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation forthe existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind's eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.

Richard Baxter

I take the love of God and self-denial to be the sum of all saving grace and religion.

Ryan Hall

The question I try and ask myself when I consider whether or not to train more is what is my body craving and what is my body ready to absorb? Sometimes pushing harder is not the answer. It takes self control, confidence, and intuition to know when to train and when to rest, but when in question error on the side of being over rested.

Russell Hoban

Too-lateness, I realized, has nothing to do with age. It’s a relation of self to the moment. Or not, depending on the person and the moment. Perhaps there even comes a time when it’s no longer too late for anything. Perhaps, even, most times are too early for most things, and most of life has to go by before it’s time for almost anything and too late for almost nothing. Nothing to lose, the present moment to gain, the integration with long-delayed Now.

Russell Brand

No-one really feels self-confident deep down because it's an artificial idea. Really, people aren't that worried about what you're doing or what you're saying, so you can drift around the world relatively anonymously: you must not feel persecuted and examined. Liberate yourself from that idea that people are watching you.

Sheikh Ahmad

He is very stubborn. When he puts his mind into something, he will do it.

Alex Solis

He really won it very easy. That's what I had in my mind, not to squeeze him.

Heywood Broun

Her mind is so open that the wind whistles through it

Dave Tippett

His mind is in the right place now.

Ta-Nehisi Coates

I think the body is the ultimate thing. The soul and mind are part of the body. I don't think there is anything outside of that. Your physical self is who you are. Some people feel that that is reductionist, but I don't think it is. It's just true.

Shane Battier

We're playing to win. I've always been of the mind-frame that you've got to play.

Rick Tocchet

We've got to try to win 2-1 right now. That's our mind-set. That's what we tried to stress today. (We said) 'Don't worry about scoring a ton of goals, just try to win 2-1' and we did.

Martin Brodeur

I thought we played really well. We've got to get the third period out of our mind and be comfortable with how we played.

Darrell Bevell

It had to do with his feet, and where his mind was at the time.
