Knowledge Quotes

Francis Bacon, Shakespeare, John Locke, Samuel Johnson and Einstein are all near the top, which gives the page its character: mostly people who thought about how we know things, rather than about how to feel clever. Johnson gives the most useful single line, in Boswell’s Life (1791): “Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.” Wittgenstein, in On Certainty (1969), says that knowledge is in the end based on acknowledgement.

A lot of the quotes people look for here are flagged. “As for me, all I know is that I know nothing” is credited to Socrates; see the note on the Wisdom page. “Contempt prior to investigation” is credited to Einstein, and a line about putting the Lord at every turn in the refuge of a miracle is credited to Galileo.

Random quote on Knowledge

Most quoted on knowledge:

It is not my place to tell you whether there is indefeasible ignorance of ultimate reality. I am ignorant of whether there is or is not. But you should think of these things because there are no things more important, though there are no questions more difficult or less answerable. But one's whole life may be changed if one changes his mind about these questions.

Lewis White Beck

You may call me an agnostic, but I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth.

Albert Einstein

We cannot exert our understanding without from time to time understanding something of importance; and this act of understanding may be accompanied by the awareness of our understanding, by the understanding of understanding, by noesis noesos, and this is so high, so pure, so noble an experience that Aristotle could ascribe it to his God.

Leo Strauss Liberalism: Ancient and Modern (1968)

So oft in theologic wars,
The disputants, I ween,
Rail on in utter ignorance
Of what each other mean,
And prate about an Elephant
Not one of them has seen!

John Godfrey Saxe

A popular Government without popular information, or the means of acquiring it, is but a Prologue to a Farce or a Tragedy, or perhaps both. Knowledge will forever govern ignorance: And a people who mean to be their own Governors, must arm themselves with the power which knowledge gives.

James Madison

Far must thy researches go
Wouldst thou learn the world to know;
Thou must tempt the dark abyss
Wouldst thou prove what Being is;
Naught but firmness gains the prize,
Naught but fullness makes us wise,
Buried deep truth e'er lies.

Friedrich Schiller

As we know, There are known knowns; there are things we know we know. We also know, there are known unknowns, that is to say, we know there are some things we do not know. But there are also unknown unknowns, the ones we do not know we do not know.

Donald Rumsfeld

The human understanding is moved by those things most which strike and enter the mind simultaneously and suddenly, and so fill the imagination; and then it feigns and supposes all other things to be somehow, though it cannot see how, similar to those few things by which it is surrounded.

Francis Bacon Novum Organum (1620)

Mark what 'tis his mind aims at in the question, and not what words he expresses it in: and when you have informed and satisfied him in that, you shall see how his thoughts will enlarge themselves, and how by fit answers he may be led on farther than perhaps you could have imagine. For knowledge is grateful to the understanding, as light to the eyes.

John Locke Some Thoughts Concerning Education (1693)

Knowing, whatever its level, is not the act by which a subject transformed into an object docilely and passively accepts the contents others give or impose on him or her. Knowledge, on the contrary, necessitates the curious presence of subjects confronted with the world. It requires their transforming action on reality. It demands a constant searching. It implies invention and reinvention. It claims from each person a reflection on the very act of knowing.

Paulo Freire Extension or Communication (1974)

According to the technical language of old writers, a thing and its qualities are described as subject and attributes; and thus a man’s faculties and acts are attributes of which he is the subject. The mind is the subject in which ideas inhere. Moreover, the man’s faculties and acts are employed upon external objects; and from objects all his sensations arise. Hence the part of a man’s knowledge which belongs to his own mind, is subjective: that which flows in upon him from the world external to him, is objective.

William Whewell

Ignorance, madam, pure ignorance.

Samuel Johnson

"Man," I cried, "how ignorant art thou in thy pride of wisdom!"

Mary Shelley

Shun too great a desire for knowledge, for in it there is much fretting and delusion. Intellectuals like to appear learned and to be called wise. Yet there are many things the knowledge of which does little or no good to the soul, and he who concerns himself about other things than those which lead to salvation is very unwise.

Thomas à Kempis

Experience certainly has long known how to think of some cheer for the troubled, but, as is natural, it does not know a joy that passes all understanding. Experience knows all the many inventions of the human heart, but a rapture that did not arise in any man’s heart it does not know.

Søren Kierkegaard

The Master said, "Yu, shall I teach you what knowledge is? When you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it; — this is knowledge."

Confucius

All schools, all colleges, have two great functions: to confer, and to conceal, valuable knowledge. The theological knowledge which they conceal cannot justly be regarded as less valuable than that which they reveal. That is, when a man is buying a basket of strawberries it can profit him to know that the bottom half of it is rotten.

Mark Twain Notebook (1908)

In the history that Franklin writes, knowledge and understanding are complementary: One without the other is incomplete. His contribution has been to make history a field of wisdom, devoid of the cult of fictitious glorification of a whole society or the cant of quantitative reductionism that analyzes parts out of context.

Charles V. Willie

Do you, good people, believe that Adam and Eve were created in the Garden of Eden and that they were forbidden to eat from the tree of knowledge? I do. The church has always been afraid of that tree. It still is afraid of knowledge. Some of you say religion makes people happy. So does laughing gas. So does whiskey. I believe in the brain of man. I'm not worried about my soul.

Clarence Darrow

How wrong it is to use God as a stop-gap for the incompleteness of our knowledge. If in fact the frontiers of knowledge are being pushed further and further back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat. We are to find God in what we know, not in what we don’t know.

Dietrich Bonhoeffer
