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:

Knowledge is the superpower of the 21st century. Even the smartest people alive when I was born did not know what 10-year-olds today have available to them. That’s truly cause for hope.

Sylvia Earle with Time (2021)

Who loves not Knowledge? Who shall rail
Against her beauty? May she mix
With men and prosper! Who shall fix
Her pillars? Let her work prevail.

Alfred, Lord Tennyson In Memoriam A.H.H (1849)

Not sure I understand
This role I've been given

Robbie Williams

Ignorance, far more than idleness, is the mother of all the vices; and how recent has been the admission, that knowledge should be the portion of all? The destinies of the future lie in judicious education; an education that must be universal, to be beneficial.

Letitia Elizabeth Landon

One must learn to know oneself before knowing anything else (gnocchi seauton). Not until a person has inwardly understood himself and then sees the course he is to take does his life gain peace and meaning.

Søren Kierkegaard

To understand fear you must also understand pleasure — they are interrelated; without understanding one you cannot understand the other. This means that one cannot say ‘I must only have pleasure and no fear’; fear is the other side of the coin which is called pleasure.

Jiddu Krishnamurti Beyond Violence (1973)

You wouldn't ask a blind man to appreciate a scene of beauty, nor a deaf man to enjoy the sounds of drums and bells. But it is possible to be blind and deaf in one's deep understanding, as well as physically.

Zhuangzi

To each his suff'rings: all are men,
Condemn'd alike to groan,
The tender for another's pain;
Th' unfeeling for his own.
Yet ah! why should they know their fate?
Since sorrow never comes too late,
And happiness too swiftly flies.
Thought would destroy their paradise.
No more; where ignorance is bliss,
'Tis folly to be wise.

Thomas Gray Ode on a Distant Prospect of Eton College (1742)

The Socratic maxim that the recognition of our ignorance is the beginning of wisdom has profound significance for our understanding of society. The first requisite for this is that we become aware of men’s necessary ignorance of much that helps him to achieve his aims.

Friedrich Hayek The Constitution of Liberty (1960)

Everything unknown is magnified.

Tacitus

Both churches and universities — insofar as they live up to their true function — serve the ennoblement of the individual. They seek to fulfill this great task by spreading moral and cultural understanding, renouncing the use of brute force.

Albert Einstein Moral Decay (1937)

Man's need of self-esteem entails the need for a sense of control over reality – but no control is possible in a universe which, by one's own concession, contains the supernatural, the miraculous and the causeless, a universe in which one is at the mercy of ghosts and demons, in which one must deal, not with the unknown, but with the unknowable; no control is possible if man proposes, but a ghost disposes; no control is possible if the universe is a haunted house.

Nathaniel Branden Mental Health versus Mysticism and Self-Sacrifice (1963)

Agape is something of the understanding, creative, redemptive goodwill for all men. It is a love that seeks nothing in return. It is an overflowing love; it’s what theologians would call the love of God working in the lives of men. And when you rise to love on this level, you begin to love men, not because they are likeable, but because God loves them.

Martin Luther King Jr.

The best student in physics or mathematics, at school or university, is not one who memorizes formulae but one who is aware of the reason for them. For students, the more simply and docilely they receive the contents with which their teachers "fill" them in the name of knowledge, the less they are able to think and the more they become merely repetitive. The best philosophy student is not one who discourses, "ipsis verbis," on the philosophy of Plato, Marx, or Kant but one who thinks critically about their ideas and takes the risk of thinking too.

Paulo Freire Extension or Communication (1974)

...the more a subject is understood, the more briefly it may be explained.

Thomas Jefferson Letter to Joseph Milligan (1816)

The essential difference between that knowledge which is, and that which is not conclusive evidence of Christian character, lies in this: the object of the one is the agreement of the several parts of a theological proposition; the object of the other is moral beauty, the intrinsic loveliness of God and Divine things. The sinner sees and hates; the saint sees and loves.

Gardiner Spring

Knowledge is one of the most scarce of all resources and a pricing system economizes on its use by forcing those with the most knowledge of their own particular situation to make bids for goods and resources based on that knowledge, rather than on their ability to influence other people in planning commissions, legislatures, or royal palaces.

Thomas Sowell Basic Economics (2010)

Do not confuse understanding with a larger vocabulary, sacred writings are beneficial in stimulating desire for inward realization, if one stanza at a time is slowly assimilated. Continual intellectual study results in vanity and the false satisfaction of an undigested knowledge.

Yukteswar Giri Autobiography of a Yogi (1946)

Who knows how many links we may have to ascend in the vast cycle of worlds around, ere we arrive at the one which is knowledge — where we may look before, and after, and judge of the whole ? How many stages of probation may we yet have to pass !

Letitia Elizabeth Landon Francesca Carrara (1834)

I think of the need for more wisdom in the world, to deal with the knowledge that we have. At one time we had wisdom, but little knowledge. Now we have a great deal of knowledge, but do we have enough wisdom to deal with that knowledge?

Jonas Salk
