Science without religion is lame, religion without science is blind.
Albert Einstein
As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.
Albert Einstein
Somewhere, something incredible is waiting to be known.
Carl Sagan
I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.
Galileo Galilei
Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.
Dr. Martin Luther King Jr.
The most incomprehensible thing about the world is that it is at all comprehensible.
Albert Einstein
I believe that a scientist looking at nonscientific problems is just as dumb as the next guy.
Richard Feynman
All truths are easy to understand once they are discovered; the point is to discover them.
Galileo Galilei
The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.
Albert Einstein
Our success in war and peace depends not on luck, or rhetoric, or the intervention of mythical gods; it depends on human character and modern scientific creations, and on respect for the meaning and methods of science.
Harlow Shapley
Every great advance in science has issued from a new audacity of imagination.
John Dewey
The greatest obstacle to discovery is not ignorance - it is the illusion of knowledge.
Daniel Boorstin
All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.
Arthur Schopenhauer
The job of a scientist is to generate wrong ideas as fast as possible.
Murray Gell-Mann
I would rather have a mind opened by wonder than one closed by belief.
Gerry Spence
If a man will begin with certainties, he shall end in doubts; but if he will be content with doubts, he shall end in certainties.
Francis Bacon
With all your science can you tell me how it is, and whence it is, that light comes into the soul?
Henry David Thoreau
What I believe in my heart must make sense in my mind.
Ravi Zacharias
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
No great advance has ever been made in science, politics, or religion, without controversy.
Lyman Beecher
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
An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem.
John Tukey
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
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
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
Correlation doesn't imply causation, but it does waggle its eyebrows suggestively and gesture furtively while mouthing 'look over there'.
Randall Munroe
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
Truth emerges much more readily from error than from confusion.
Francis Bacon
There's no sense in being precise when you don't even know what you're talking about.
John Von Neumann
Natural selection has built us, and it is natural selection we must understand if we are to comprehend our own identities.
Richard Dawkins
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
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
The first principle is that you must not fool yourself—and you are the easiest person to fool.

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

The imagination of nature is far, far greater than the imagination of man.
Richard Feynman

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

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

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

There is one rule that's very simple, but not easy: observe reality and adjust.
Ran Prieur
[E]xperiment and observation is the sole and ultimate judge of the truth of an idea

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

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