Aristotle quote: “All men by nature desire knowledge.”

“There is no desire more natural than the desire of knowledge.”

Michel De Montaigne (1533–1592) (1533-1592) French-Occitan author, humanistic philosopher, statesman

“A desire for knowledge is the natural feeling of mankind; and every human being, whose mind is not debauched, will be willing to give all he has to get knowledge.”

Samuel Johnson London

Dr. Johnson’s Table Talk (London: 1807), p. 64

“It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting.”

William Kingdon Clifford (1845–1879) English mathematician and philosopher

The Ethics of Belief (1877), The Duty of Inquiry
Context: Belief, that sacred faculty which prompts the decisions of our will, and knits into harmonious working all the compacted energies of our being, is ours not for ourselves but for humanity. It is rightly used on truths which have been established by long experience and waiting toil, and which have stood in the fierce light of free and fearless questioning. Then it helps to bind men together, and to strengthen and direct their common action. It is desecrated when given to unproved and unquestioned statements, for the solace and private pleasure of the believer; to add a tinsel splendour to the plain straight road of our life and display a bright mirage beyond it; or even to drown the common sorrows of our kind by a self-deception which allows them not only to cast down, but also to degrade us. Whoso would deserve well of his fellows in this matter will guard the purity of his beliefs with a very fanaticism of jealous care, lest at any time it should rest on an unworthy object, and catch a stain which can never be wiped away.
It is not only the leader of men, statesmen, philosopher, or poet, that owes this bounden duty to mankind. Every rustic who delivers in the village alehouse his slow, infrequent sentences, may help to kill or keep alive the fatal superstitions which clog his race. Every hard-worked wife of an artisan may transmit to her children beliefs which shall knit society together, or rend it in pieces. No simplicity of mind, no obscurity of station, can escape the universal duty of questioning all that we believe.
It is true that this duty is a hard one, and the doubt which comes out of it is often a very bitter thing. It leaves us bare and powerless where we thought that we were safe and strong. To know all about anything is to know how to deal with it under all circumstances. We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. And if we have supposed ourselves to know all about anything, and to be capable of doing what is fit in regard to it, we naturally do not like to find that we are really ignorant and powerless, that we have to begin again at the beginning, and try to learn what the thing is and how it is to be dealt with — if indeed anything can be learnt about it. It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting.

“It is of the nature of desire not to be satisfied, and most men live only for the gratification of it.”

Book II, 1267b.4

“Most men and women, by birth or nature, lack the means to advance in wealth and power, but all have the ability to advance in knowledge.”

Pythagoras (-585–-495 BC) ancient Greek mathematician and philosopher

As quoted in The Golden Ratio (2002) by Mario Livio

“for it was not knowledge but unity that she desired, not inscriptions on tablets, nothing that could be written in any language known to men, but intimacy itself, which is knowledge”

Virginia Woolf book To the Lighthouse

Part I, Ch. 9
Source: To the Lighthouse (1927)
Context: Could loving, as people called it, make her and Mrs Ramsay one? for it was not knowledge but unity that she desired, not inscription on tablets, nothing that could be written in any language known to men, but intimacy itself, which is knowledge, she had thought, leaning her head on Mrs Ramsay's knee.

“The greatest error of all the rest is the mistaking or misplacing of the last or farthest end of knowledge: for men have entered into a desire of learning and knowledge, sometimes upon a natural curiosity and inquisitive appetite; sometimes to entertain their minds with variety and delight; sometimes for ornament and reputation; and sometimes to enable them to victory of wit and contradiction; and most times for lucre and profession; and seldom sincerely to give a true account of their gift of reason, to the benefit and use of men”

Francis Bacon book The Advancement of Learning

Book I, v, 11
The Advancement of Learning (1605)
Context: The greatest error of all the rest is the mistaking or misplacing of the last or farthest end of knowledge: for men have entered into a desire of learning and knowledge, sometimes upon a natural curiosity and inquisitive appetite; sometimes to entertain their minds with variety and delight; sometimes for ornament and reputation; and sometimes to enable them to victory of wit and contradiction; and most times for lucre and profession; and seldom sincerely to give a true account of their gift of reason, to the benefit and use of men: as if there were sought in knowledge a couch whereupon to rest a searching and restless spirit; or a tarrasse, for a wandering and variable mind to walk up and down with a fair prospect; or a tower of state, for a proud mind to raise itself upon; or a fort or commanding ground, for strife and contention; or a shop, for profit or sale; and not a rich storehouse, for the glory of the Creator and the relief of man's estate.
