More quotes about:

What I believe in my heart must make sense in my mind. Ravi Zacharias Quote Details

More quotes about:

At the heart of science is an essential tension between two seemingly contradictory attitudes - an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. Of course, scientists make mistakes in trying to understand the world, but there is a built-in error-correcting mechanism: The collective enterprise of creative thinking and skeptical thinking together keeps the field on track. Carl Sagan Quote Details

More quotes about:

No great advance has ever been made in science, politics, or religion, without controversy. Lyman Beecher Quote Details

More quotes about:

There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle. Albert Einstein Quote Details

More quotes about:

An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem. John Tukey Quote Details

More quotes about:

It is fine to be ignorant of a great many things; nobody has time to understand more than a few things deeply. But in those numerous topics on which we are not experts, we are nevertheless tempted to construct a coherent-seeming but illusory image of reality, and believe it with undue certainty. We are far too sure of ourselves when we have not earned it. Overcertainty is an anchor, undue inertia, dragging feet, when we should really be leaves on the winds of evidence. Xan Quote Details

More quotes about:

The most important factor in the training of good mental habits consists in acquiring the attitude of suspended conclusion, and in mastering the various methods of searching for new materials to corroborate or to refute the first suggestions that occur. John Dewey Quote Details

More quotes about:

The man who believes that the secrets of this world are forever hidden lives in mystery and fear. Superstition will drag him down. The rain will erode the deeds of his life. But that man who sets himself the task of singling out the thread of order from the tapestry will by the decision alone have taken charge of the world and it is only by such taking charge that he will effect a way to dictate the terms of his own fate. Cormac McCarthy Quote Details

More quotes about:

Correlation doesn't imply causation, but it does waggle its eyebrows suggestively and gesture furtively while mouthing 'look over there'. Randall Munroe Quote Details

More quotes about:

Natural selection built the brain to survive in the world and only incidentally to understand it at a depth greater than is needed to survive. The proper task of scientists is to diagnose and correct the misalignment. E. O. Wilson Quote Details

More quotes about:

Truth emerges much more readily from error than from confusion. Francis Bacon Quote Details

More quotes about:

There's no sense in being precise when you don't even know what you're talking about. John Von Neumann Quote Details

More quotes about:

Natural selection has built us, and it is natural selection we must understand if we are to comprehend our own identities. Richard Dawkins Quote Details

More quotes about:

Our imagination is stretched to the utmost, not, as in fiction, to imagine things which are not really there, but just to comprehend those things which are there. Richard Feynman Quote Details

More quotes about:

Science is the belief in the ignorance of experts. Richard Feynman Quote Details

More quotes about:

Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?" Richard Feynman Quote Details

More quotes about:

The first principle is that you must not fool yourself—and you are the easiest person to fool. Richard Feynman Quote Details

Scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to use it. Richard Feynman Quote Details

More quotes about:

This is the source.

The imagination of nature is far, far greater than the imagination of man. No one who did not have some inkling of this through observations could ever have imagined such a marvel as nature is. Richard Feynman Quote Details

More quotes about:

This is the source.

We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty—some most unsure, some nearly sure, but none absolutely certain. Richard Feynman Quote Details

More quotes about:

This is the source.

What, then, is the meaning of it all? What can we say to dispel the mystery of existence? If we take everything into account—not only what the ancients knew, but all of what we know today that they didn't know—then I think we must frankly admit that we do not know. But, in admitting this, we have probably found the open channel. Richard Feynman Quote Details

More quotes about:

This is the source.

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on. It is our responsibility to leave the people of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant as we are. If we suppress all discussion, all criticism, proclaiming "This is the answer, my friends; man is saved!" we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before. It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations. Richard Feynman Quote Details

More quotes about:

There is one rule that's very simple, but not easy: observe reality and adjust. Ran Prieur Quote Details

More quotes about:

[E]xperiment and observation is the sole and ultimate judge of the truth of an idea. Richard Feynman Quote Details

More quotes about:

This is the source.

Learn by trying to understand simple things in terms of other ideas—always honestly and directly. What keeps the clouds up, why can't I see stars in the daytime, why do colors appear on oily water, what makes the lines on the surface of water being poured from a pitcher, why does a hanging lamp swing back and forth—and all the innumerable little things you see all around you. Then when you have learned to explain simpler things, so you have learned what an explanation really is, you can then go on to more subtle questions. Richard Feynman Quote Details

The greatest enemy of knowledge is not ignorance. It is the illusion of knowledge. Stephen Hawking Quote Details

More quotes about:

Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry. Richard Feynman Quote Details

More quotes about:

I believe that understanding what is good is obtained by looking at the way the world works and figuring out how to operate in harmony with it to help it (and yourself) evolve. Ray Dalio Quote Details

More quotes about:

This is the source.

Though how nature works is way beyond man's ability to comprehend, I have found that observing how nature works offers innumerable lessons that can help us understand the realities that affect us. Ray Dalio Quote Details

More quotes about:

This is the source.

I believe there are an infinite number of laws of the universe and that all progress or dreams achieved come from operating in a way that's consistent with them. These laws and the principles of how to operate in harmony with them have always existed. We were given these laws by nature. Man didn't and can't make them up. He can only hope to understand them and use them to get what he wants. Ray Dalio Quote Details

More quotes about:

This is the source.

As children look out upon the world with wide, uncritical, undemanding, innocent eyes, simply noting and observing what is the case, without either arguing the matter or demanding that it be otherwise, so do self-actualizing people tend to look upon human nature in themselves and in others. Abraham Maslow Quote Details

More quotes about:

[Y]ou should not let yourself believe whatever comes to your mind. To be useful, your beliefs should be constrained by the logic of probability. Daniel Kahneman Quote Details

More quotes about:

Science is simply the method we use to try and postulate a minimum set of assumptions that can explain, through a straightforward logical derivation, the existence of many phenomena of nature. Eliyahu Goldratt Quote Details

More quotes about:

Many philosophers—particularly amateur philosophers, and ancient philosophers—share a dangerous instinct: If you give them a question, they try to answer it. Eliezer Yudkowsky Quote Details

More quotes about:

Man cannot make or invent or contrive principles. He can only discover them and he ought to look through the discovery to the Author. Thomas Paine Quote Details

More quotes about:

A good stack of examples, as large as possible, is indispensable for a thorough understanding of any concept, and when I want to learn something new, I make it my first job to build one. Paul Halmos Quote Details

More quotes about:

A physicist is an atom's way of knowing about atoms. George Wald Quote Details

More quotes about:

Every generation before us believed...that it had things figured out. We now know that every generation before us was wrong about a lot of it. Is it likely that you were born at the tipping point of history, in which humans know enough about reality to say we understand it? This is another case where humility is your friend. When you can release on your ego long enough to view your perceptions as incomplete or misleading, it gives you the freedom to imagine new and potentially more useful ways of looking at the world. Scott Adams Quote Details

All models are wrong, but some are useful. George Box Quote Details

More quotes about:

If you look closely enough at anything, you will see that there is nothing more exciting than the truth. Richard Feynman Quote Details

More quotes about:

This is the source.

All other aspects and characteristics of science can be understood directly when we understand that observation is the ultimate and final judge of the truth of an idea. Richard Feynman Quote Details

More quotes about:

This is the source.

The principle that observation is the judge imposes a severe limitation to the kind of questions that can be answered. They are limited to questions that you can put this way: “If I do this, what will happen?” There are ways to try it and see. Questions like, “Should I do this?” and “What is the value of this?” are not of the same kind. Richard Feynman Quote Details

So what we call scientific knowledge today is a body of statements of varying degrees of certainty. Some of them are most unsure; some of them are nearly sure; but none is absolutely certain. Richard Feynman Quote Details

More quotes about:

This is the source.

Some people say, “How can you live without knowing?” I do not know what they mean. I always live without knowing. That is easy. How you get to know is what I want to know. Richard Feynman Quote Details

More quotes about:

This is the source.

This freedom to doubt is an important matter in the sciences and, I believe, in other fields. It was born of a struggle. It was a struggle to be permitted to doubt, to be unsure. And I do not want us to forget the importance of the struggle and, by default, to let the thing fall away. I feel a responsibility as a scientist who knows the great value of a satisfactory philosophy of ignorance, and the progress made possible by such a philosophy, progress which is the fruit of freedom of thought. I feel a responsibility to proclaim the value of this freedom and to teach that doubt is not to be feared, but that it is to be welcomed as the possibility of a new potential for human beings. If you know that you are not sure, you have a chance to improve the situation. I want to demand this freedom for future generations. Richard Feynman Quote Details

More quotes about:

This is the source.

Throughout all the ages, men have been trying to fathom the meaning of life. They realize that if some direction or some meaning could be given to the whole thing, to our actions, then great human forces would be unleashed. So, very many answers have been given to the question of the meaning of it all. But they have all been of different sorts. And the proponents of one idea have looked with horror at the actions of the believers of another—horror because from a disagreeing point of view all the great potentialities of the race were being channeled into a false and confining blind alley. In fact, it is from the history of the enormous monstrosities that have been created by false belief that philosophers have come to realize the fantastic potentialities and wondrous capacities of human beings. The dream is to find the open channel. What, then, is the meaning of it all? What can we say today to dispel the mystery of existence? If we take everything into account, not only what the ancients knew, but also all those things that we have found out up to today that they didn't know, then I think that we must frankly admit that we do not know. But I think that in admitting this we have probably found the open channel. Admitting that we do not know, and maintaining perpetually the attitude that we do not know the direction necessarily to go, permit a possibility of alteration, of thinking, of new contributions and new discoveries for the problem of developing a way to do what we want ultimately, even when we do not know what we want. Richard Feynman Quote Details

That something is unscientific is not bad; there is nothing the matter with it. It is just unscientific. And scientific is limited, of course, to those things that we can tell about by trial and error. Richard Feynman Quote Details

More quotes about:

So in life, in gaiety, in emotion, in human pleasures and pursuits, and in literature and so on, there is no need to be scientific, there is no reason to be scientific. One must relax and enjoy life. Richard Feynman Quote Details
