Knowledge

"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.""

"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."

"To know one's ignorance is the best part of knowledge. To be ignorant of such knowledge is a disease. If one only regards it as a disease, he will be cured of it. The wise man is exempt from this disease. He knows it for what it is, and hence is free from it."

"I cannot look at something through someone else's eyes. I can only truly know something which I know."

"Everyone in the world knows how to seek for knowledge that they do not have, but do not know how to find what they already know."

"For knowing is spoken of in three ways: it may be either universal knowledge or knowledge proper to the matter in hand or actualising such knowledge; consequently three kinds of error also are possible."

"All teaching and all intellectual learning come about from already existing knowledge."

"Πάντες ἄνθρωποι τοῦ εἰδέναι ὀρέγονται φύσει. Σημεῖον δ᾽ ἡ τῶν αἰσθήσεων ἀγάπησις: καὶ γὰρ χωρὶς τῆς χρείας ἀγαπῶνται δι᾽ αὑτάς, καὶ μάλιστα τῶν ἄλλων ἡ διὰ τῶν ὀμμάτων. Οὐ γὰρ μόνον ἵνα πράττωμεν ἀλλὰ καὶ μηθὲν μέλλοντες πράττειν τὸ ὁρᾶν αἱρούμεθα ἀντὶ πάντων ὡς εἰπεῖν τῶν ἄλλων. Αἴτιον δ᾽ ὅτι μάλιστα ποιεῖ γνωρίζειν ἡμᾶς αὕτη τῶν αἰσθήσεων καὶ πολλὰς δηλοῖ διαφοράς."

"He who chooses to know for the sake of knowing will choose most readily that which is most truly knowledge."

"γνῶθι σεαυτόν."

"This is the bitterest pain among men, to have much knowledge but no power."

"Thales was asked what was very difficult; he said: "To know one's self.""

"Πᾶσα τε ἐπιστήμη χωριζομένη δικαιοσύνης καὶ τῆς ἄλλης ἀρετῆς πανουργία, οὐ σοφία φαίνεται."

"Ἕν οἶδα, ὅτι οὐδὲν οἶδα."

"Φεῦ φεῦ, φρονεῖν ὡς δεινὸν ἔνθα μὴ τέλη / λύῃ φρονοῦντι..."

"Prima sapientiae clavis definitur, assidua scilicet seu frequens interrogatio … Dubitando enim ad inquisitionem venimus; inquirendo veritatem percipimus."

"To wisdom belongs the intellectual apprehension of things eternal; to knowledge, the rational apprehension of things temporal."

"Nam non solum scire aliquid, artis est, sed, quædam ars etiam docendi."

"Minime sibi quisque notus est, et difficillime de se quisque sentit."

"Nescire autem quid ante quam natus sis acciderit, id est semper esse puerum."

"Nec scire fas est omnia."

"Si quid novisti rectius istis. Candidus imperti, si non, his utere mecum."

"E cœlo descendit nosce te ipsum."

"Scire est nescire, nisi id me scire alius scierit."

"Quid nobis certius ipsis Sensibus esse potest? qui vera ac falso notemus."

"Et teneo melius ista quam meum nomen."

"Scire tuum nihil est, nisi te scire hoc sciat alter?"

"Ego te intus et in cute novi."

"Plus scire satius est, quam loqui."

"Natura semina scientiæ nobis dedit, scientiam non dedit."

"Namque inscitia est, Adversum stimulum calces."

"Faciunt næ intelligendo, ut nihil intelligant."

"Do you know how God controls the clouds and how he causes the lightning to flash from his cloud? Do you know how the clouds float? These are the wonderful works of the One perfect in knowledge."

"They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea."

"Through wisdom is an house builded; and by understanding it is established: And by knowledge shall the chambers be filled with all precious and pleasant riches."

"Many shall run to and fro, and knowledge shall be increased."

"The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge."

"In vain have you acquired knowledge if you do not impart it it to others."

"He that increaseth knowledge increaseth sorrow."

"The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction."

"When wisdom enters your heart"

"Whoever loves discipline loves knowledge."

"O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!"

"O the depth of God’s riches and wisdom and knowledge! How unsearchable his judgments are and beyond tracing out his ways are! For “who has come to know Jehovah’s mind, or who has become his adviser?” Or, “who has first given to him, so that it must be repaid to him?” Because from him and by him and for him are all things. To him be the glory forever. Amen."

"And (mention, O Muhammad), when your Lord said to the angels, "Indeed, I will make upon the earth a successive authority." They said, "Will You place upon it one who causes corruption therein and sheds blood, while we declare Your praise and sanctify You?" He (God) said: Surely, I know what you know not."

"They (angels) said, "Exalted are You; we have no knowledge except what You have taught us. Indeed, it is You who is the Knowing, the Wise.""

"And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart – about all those (one) will be questioned."

"So high (above all) is God, the Sovereign, the Truth. And, (O Muhammad), do not hasten with (recitation of) the Qur'an before its revelation is completed to you, and say, "My Lord, increase me in knowledge.""

"There is another form of temptation, more complex in its peril. … It originates in an appetite for knowledge. … From this malady of curiosity are all those strange sights exhibited in the theatre. Hence do we proceed to search out the secret powers of nature (which is beside our end), which to know profits not, and wherein men desire nothing but to know."

"Without any delusive representation of images or phantasms, I am most certain that I am, and that I know and delight in this. In respect of these truths, I am not at all afraid of the arguments of the Academicians, who say, What if you are deceived? For if I am deceived, I am. For he who is not, cannot be deceived; and if I am deceived, by this same token I am. And since I am if I am deceived, how am I deceived in believing that I am? for it is certain that I am if I am deceived. Since, therefore, I, the person deceived, should be, even if I were deceived, certainly I am not deceived in this knowledge that I am."

"The one who thinks he knows something does not yet know as he ought to know."

"A name made great is a name destroyed. He who does not increase his knowledge decreases it."

"The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes. Therefore in medicine we ought to know the causes of sickness and health. And because health and sickness and their causes are sometimes manifest, and sometimes hidden and not to be comprehended except by the study of symptoms, we must also study the symptoms of health and disease. Now it is established in the sciences that no knowledge is acquired save through the study of its causes and beginnings, if it has had causes and beginnings; nor completed except by knowledge of its accidents and accompanying essentials. Of these causes there are four kinds: material, efficient, formal, and final."

"Prudens quaestio dimidium scientiae."

"...if perception is only knowledge or a means towards knowledge; since he who perceives, has knowledge thereby, according to the special character of the senses, by sight of colours, by taste of savours and so forth: then whatsoever has knowledge in whatsoever manner may be said without impropriety in some sense to perceive. Therefore, O Lord, although Thou art not a body, yet of a truth Thou hast in this sense perception in the highest degree, since Thou knowest all things in the highest degree; but not in the sense wherein an animal that has knowledge by means of bodily feeling is said to have perception."

"Knowledge comes Of learning well retain'd, unfruitful else."

"The eye with which I see God is the same with which God sees me. My eye and God's eye is one eye, and one sight, and one knowledge, and one love."

"Knowledge comes through likeness. And so because the soul may know everything, it is never at rest until it comes to the original idea, in which all things are one. And there it comes to rest in God."

"For the more a man knows, the more worthy he is."

"You must know that if a person, who has attained a certain degree of perfection, wishes to impart to others, either orally or in writing, any portion of the knowledge which he has acquired of these subjects, he is utterly unable to be as systematic and explicit as he could be in a science of which the method is well known. The same difficulties which he encountered when investigating the subject for himself will attend him when endeavouring to instruct others: viz., at one time the explanation will appear lucid, at another time, obscure: this property of the subject appears to remain the same both to the advanced scholar and to the beginner. For this reason, great theological scholars gave instruction in all such matters only by means of metaphors and allegories."

"sic: si omnes homines natura scire desiderant, ergo maxime scientiam maxime desiderabunt. Ita arguit Philosophus I huius cap. 2. Et ibidem subdit: "quae sit maxime scientia, illa scilicet quae est circa maxime scibilia". Maxime autem dicuntur scibilia dupliciter: uel quia primo omnium sciuntur sine quibus non possunt alia sciri; uel quia sunt certissima cognoscibilia. Utroque autem modo considerat ista scientia maxime scibilia. Haec igitur est maxime scientia, et per consequens maxime desiderabilis."

"You must acquire the best knowledge first, and without delay; it is the height of madness to learn what you will later have to unlearn."

"If thou knewest the whole Bible by heart, and the sayings of all the philosophers, what would it profit thee without the love of God and without grace?"

"Every man naturally desires knowledge; but what good is knowledge without fear of God? Indeed a humble rustic who serves God is better than a proud intellectual who neglects his soul to study the course of the stars."

"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."

"He knew what is what."

"I have taken all knowledge to be my province."

"Knowledge is power."

"Knowledge and human power are synonymous, since the ignorance of the cause frustrates the effect."

"Knowledge bloweth up, but charity buildeth up."

"Nam et ipsa scientia potestas est."

"For knowledge, too, is itself a power."

"I find that even those that have sought knowledge for itself, and not for benefit, or ostentation, or any practicable enablement in the course of their life, have nevertheless propounded to themselves a wrong mark, namely, satisfaction, which men call truth, and not operation. For as in the courts and services of princes and states, it is a much easier matter to give satisfaction than to do the business; so in the inquiring of causes and reasons it is much easier to find out such causes as will satisfy the mind of man and quiet objections, than such causes as will direct him and give him light to new experiences and inventions."

"Knowledge that stays at the tip of one's tongue Can always be used and expressed by the learned. The fool is deceived by what needs reference To a teacher or text for support."

"Manners must adorn knowledge, and smooth its way through the world. Like a great rough diamond, it may do very well in a closet by way of curiosity, and also for its intrinsic value; but it will never be worn, nor shine, if it is not polished."

"Scientia non habet inimicum nisi ignorantem"

"Que nuist savoir tousjours et tousjours apprendre, fust ce D'un sot, d'une pot, d'une que—doufle D'un mouffe, d'un pantoufle."

"Then I began to think, that it is very true which is commonly said, that the one-half of the world knoweth not how the other half liveth."

"And seeing ignorance is the curse of God, Knowledge the wing wherewith we fly to heaven."

"Too much to know is to know naught but fame."

"But the full sum of me * * Is an unlesson'd girl, unschool'd, unpractis'd; Happy in this, she is not yet so old But she may learn."

"Crowns have their compass—length of days their date— Triumphs their tomb—felicity, her fate— Of nought but earth can earth make us partaker, But knowledge makes a king most like his Maker."

"And thou my minde aspire to higher things; Grow rich in that which never taketh rust."

"Sweet food of sweetly uttered knowledge."

"Yet all that I have learn'd (hugh toyles now past) By long experience, and in famous schooles, Is but to know my ignorance at last. Who think themselves most wise are greatest fools."

"For all knowledge and wonder (which is the seed of knowledge) is an impression of pleasure in itself."

"There is oftentimes a great deal of knowledge where there is but little wisdom to improve that knowledge. It is not the most knowing Christian but the most wise Christian that sees, avoids, and escapes Satan's snares. Knowledge without wisdom is like mettle in a blind horse, which is often an occasion of the rider's fall."

"He knew what's what, and that's as high As metaphysic wit can fly."

"Deep sighted in intelligences, Ideas, atoms, influences."

"Nor do I know what is become Of him, more than the Pope of Rome."

"He knew whats'ever 's to be known, But much more than he knew would own."

"But ask not bodies (doomed to die), To what abode they go; Since knowledge is but sorrow's spy, It is not safe to know."

"Il connoît l'univers, et ne se connoît pas."

"Knowledge is folly unless grace guide it."

"Virtue is harder to be got than knowledge of the world; and, if lost in a young man, is seldom recovered."

"The only fence against the world is a thorough knowledge of it, into which a young gentleman should be enter'd by degrees, as he can bear it; and the earlier the better, so he be in safe and skillful hands to guide him. The scene should be gently open'd, and his entrance made step by step, and the dangers pointed out that attend him from several degrees, tempers, designs, and clubs of men. He should be prepared to be shocked by some, and caress'd by others; warned who are like to oppose, who to mislead, who to undermine him, and who to serve him. He should be instructed how to know and distinguish them; where he should let them see, and when dissemble the knowledge of them and their aims and workings."

"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."

"For in particulars our knowledge begins, and so spreads itself, by degrees, to generals [Footnote: This is the order in time of the conscious acquistion of knowledge that is human. The Essay might be regarded as a commentary on this one sentence. Our intellectual progress is from particulars and involuntary recipiency, through reactive doubt and criticism, into what is at last reasoned faith.]. Though afterwards the mind takes the quite contrary course, and having drawn its knowledge into as general propositions as it can, makes those familiar to its thoughts, and accustoms itself to have recourse to them, as to the standards of truth and falsehood. [Footnote: This is the philosophic attitude. Therein one consciously apprehends the intellectual necessities that were UNCONCIOUSLY PRESUPPOSED, its previous intellectual progress. In philosophy we 'draw our knowledge into as general propositions as it can' be made to assume, and thus either learn to see it as an organic while in a speculative unity, or learn that it cannot be so seen in a finite intelligence, and that even at the last it must remain 'broken' and mysterious in the human understanding.]"

"I went into the temple, there to hear The teachers of our law, and to propose What might improve my knowledge or their own."

"The end of learning is to know God, and out of that knowledge to love Him and imitate Him."

"Vous parlez devant un homme à qui tout Naples est connu."

"Faites comme si je ne le savais pas."

"Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things. As the world, which to the naked eye exhibits the greatest variety of objects, appears very simple in its internal constitution when surveyed by a philosophical understanding, and so much the simpler by how much the better it is understood, so it is in the visions. It is the perfection of God's works that they are all done with the greatest simplicity. He is the God of order and not of confusion. And therefore as they would understand the frame of the world must endeavor to reduce their knowledge to all possible simplicity, so must it be in seeking to understand these visions."

"All things I thought I knew; but now confess The more I know, I know, I know the less."

"Knowledge of physical science will not console me for ignorance of morality in time of affliction, but knowledge of morality will always console me for ignorance of physical science."

"Nous sommes sur un milieu vaste, toujours incertains et flottants entre l'ignorance et la connaissance ; et si nous pensons aller plus avant, notre objet branle, et échappe nos prises ; il se dérobe, et fuit d'une fuite éternelle : rien ne le peut arrêter. C'est notre condition naturelle et, toutefois, la plus contraire à notre inclination. Nous brûlons du désir d'approfondir tout et d'édifier une tour qui s'élève jusqu'à l'infini. Mais tout notre édifice craque, et la terre s'ouvre jusqu'aux abîmes."

"..it is impossible that our rational part should be other than spiritual; and if any one maintain that we are simply corporeal, this would far more exclude us from the knowledge of things, there being nothing so inconceivable as to say that matter knows itself. It is impossible to imagine how it should know itself."

"We know what we are, but know not what we may be."

"If you can look into the seeds of time, And say which grain will grow and which will not; Speak then to me."

"Knowledge is, indeed, that which, next to virtue, truly and essentially raises one man above another."

"Knowledge and Wisdom, far from being one, Have oft-times no connexion. Knowledge dwells In heads replete with thoughts of other men, Wisdom in minds attentive to their own."

"Knowledge is proud that he has learned so much; Wisdom is humble that he knows no more."

"What must be the knowledge of Him, from whom all created minds have derived both their power of knowledge, and the innumerable objects of their knowledge! What must be the wisdom of Him, from whom all things derive their wisdom!"

"Life is a jest; and all things show it. I thought so once; and now I know it."

"Upon the progress of knowledge the whole progress of the human race is immediately dependent: he who retards that, hinders this also. And he who hinders this, — what character does he assume towards his age and posterity? Louder than with a thousand voices, by his actions he proclaims into the deafened ear of the world present and to come — "As long as I live at least, the men around me shall not become wiser or better; — for in their progress I too, notwithstanding all my efforts to the contrary, should be dragged forward in some direction; and this I detest I will not become more enlightened, — I will not become nobler. Darkness and perversion are my elements, and I will summon all my powers together that I may not be dislodged from them.""

"Was man nicht versteht, besitzt man nicht."

"Eigentlich weiss man nur wenn man wenig weiss; mit dem Wissen wächst der Zweifel."

"Who can direct, when all pretend to know?"

"Knowledge is more than equivalent to force. The master of mechanicks laughs at strength."

"Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful."

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

"Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it."

"That all our knowledge begins with experience there can be no doubt. For how is it possible that the faculty of cognition should be awakened into exercise otherwise than by means of objects which affect our senses, and partly of themselves produce representations, partly rouse our powers of understanding into activity, to compare, to connect, or to separate these, and so to convert the raw material of our sensuous impressions into a knowledge of objects, which is called experience? In respect of time, therefore, no knowledge of ours is antecedent to experience, but begins with it. But though all our knowledge begins with experience, it by no means follows, that all arises out of experience. For, on the contrary, it is quite possible that our empirical knowledge is a compound of that which we receive through impressions, and that which the faculty of cognition supplies from itself (sensuous impressions giving merely the occasion)... It is, therefore, a question which requires close investigation, and is not to be answered at first sight,—whether there exists a knowledge altogether independent of experience, and even of all sensuous impressions? Knowledge of this kind is called à priori, in contradistinction to empirical knowledge which has its sources à posteriori, that is, in experience."

"Wer viel weiss Hat viel zu sorgen."

"Reading furnishes the mind only with materials of knowledge; it is thinking makes what we read ours."

"The improvement of the understanding is for two ends: first, for our own increase of knowledge; secondly, to enable us to deliver and make out that knowledge to others."

"Diffused knowledge immortalizes itself."

"A little knowledge is a dangerous thing"

"That virtue only makes our bliss below, And all our knowledge is ourselves to know."

"In vain sedate reflections we would make When half our knowledge we must snatch, not take."

"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."

"Willst du dich selber erkennen, so sieh' wie die andern es treiben; Willst du die andern versteh'n, blick in dein eigenes Herz."

"Wouldst thou know thyself, observe the actions of others. Wouldst thou other men know, look thou within thine own heart."

"Much learning shows how little mortals know; Much wealth, how little worldlings can enjoy."

"Oh, be wise, Thou! Instructed that true knowledge leads to love."

"Real knowledge, like every thing else of the highest value, is not to be obtained easily. It must be worked for, — studied for, — thought for, — and, more than all, it must be prayed for."

"What a man knows should find its expression in what he does. The value of superior knowledge is chiefly in that it leads to a performing manhood."

"Knowledge by suffering entereth, And life is perfected by death."

"Pursuit of knowledge under difficulties."

"Real knowledge never promoted either turbulence or unbelief; but its progress is the forerunner of liberality and enlightened toleration."

"The tree of knowledge is not that of life."

"Knowledge is not happiness, and science But an exchange of ignorance for that Which is another kind of ignorance."

"And is this the prime And heaven-sprung message of the olden time?"

"There's lots of people—this town wouldn't hold them; Who don't know much excepting what's told them."

"For love is ever the beginning of Knowledge, as fire is of light."

"What is all Knowledge too but recorded Experience, and a product of History; of which, therefore, Reasoning and Belief, no less than Action and Passion, are essential materials?"

"To be conscious that you are ignorant is a great step to knowledge."

"How calmly and genially the mind apprehends one after another the laws of physics! What noble emotions dilate the mortal as he enters into the counsels of the creation, and feels by knowledge the privilege to Be! His insight refines him. The beauty of nature shines in his own breast. Man is greater that he can see this, and the universe less, because Time and Space relations vanish as laws are known. Here again we are impressed and even daunted by the immense Universe to be explored. "What we know, is a point to what we do not know.""

"There is no knowledge that is not power."

"Our knowledge is the amassed thought and experience of innumerable minds."

"Knowledge is the antidote to fear,— Knowledge, Use and Reason, with its higher aids."

"The Doctrine of Knowledge, apart from all special and definite knowing, proceeds immediately upon Knowledge itself, in the essential unity in which it recognises Knowledge as existing; and it raises this question in the first place — How this Knowledge can come into being, and what it is in its inward and essential Nature? The following must be apparent: — There is but One who is absolutely by and through himself, — namely, God; and God is not the mere dead conception to which we have thus given utterance, but he is in himself pure Life. He can neither change nor determine himself in aught within himself, nor become any other Being; for his Being contains within it all his Being and all possible Being, and neither within him nor out of him can any new Being arise."

"It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment. When I have clarified and exhausted a subject, then I turn away from it, in order to go into darkness again; The never-satisfied man is so strange—if he has completed a structure, then it is not in order to dwell in it peacefully, but in order to begin another. I imagine the world conqueror must feel thus, who, after one kingdom is scarcely conquered, stretches out his arms again for others."

"The first step to self-knowledge is self-distrust. Nor can we attain to any kind of knowledge, except by a like process."

"There are a multitude of allied branches of knowledge connected with man's condition; the relation of these to political economy is analogous to the connexion of mechanics, astronomy, optics, sound, heat, and every other branch more or less of physical science, with pure mathematics."

"Knowledge of the truth I may perhaps have attained to; happiness certainly not. What shall I do? Accomplish something in the world, men tell me. Shall I then publish my grief to the world, contribute one more proof for the wretchedness and misery of existence, perhaps discover a new flaw in human life, hitherto unnoticed? I might then reap the rare reward of becoming famous, like the man who discovered the spots on Jupiter. I prefer, however, to keep silent."

"Not if I know myself at all."

"Knowledge, when only the possession of a few, has almost always been turned to iniquitous purposes."

"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 !"

"As all true virtue, wherever found, is a ray of the life of the All-Holy; so all solid knowledge, all really accurate thought, descends from the Eternal Reason, and ought, when we apprehend it, to guide us upwards to Him."

"'Tain't a knowin' kind of cattle Thet is ketched with mouldy corn."

"To the man who aspires to know, no man who has been the meanest student of knowledge should be unknown."

"A kind of semi-Solomon, half-knowing everything, from the cedar to the hyssop."

"Let me always remember that it is not the amount of religious knowledge which I have, but the amount which I use, that determines my religious position and character."

"Every addition to true knowledge is an addition to human power."

"As revelation is the great strengthener of reason, the march of mind which leaves the Bible in the rear, is an advance, like that of our first parents in Paradise, towards knowledge, but, at the same time, towards death."

"Only by knowledge of that which is not thyself, shall thyself be learned."

"To understand at all what life means, one must begin with Christian belief. And I think knowledge may be sorrow with a man unless he loves."

"The scientists take for granted that the education of the schools creates intelligence; very often it does no such thing. It creates a superficial appearance of knowledge indeed; but knowledge is like food, unless it be thoroughly assimilated when absorbed, and thoroughly digested, it can give no nourishment; it lies useless, a heavy and unleavened mass."

"It is not in the books of the Philosophers, but in the religious symbolism of the Ancients, that we must look for the footprints of Science, and re-discover the Mysteries of Knowledge."

"The fear of speculation, the ostensible rush from the theoretical to the practical, brings about the same shallowness in action that it does in knowledge. It is by studying a strictly theoretical philosophy that we become most acquainted with Ideas, and only Ideas provide action with energy and ethical significance."

"Every increase of knowledge may possibly render depravity more depraved, as well as it may increase the strength of virtue. It is in itself only power; and its value depends on its application."

"A life of knowledge is not often a life of injury and crime."

"Every man is a valuable member of society who, by his observations, researches, and experiments, procures knowledge for men … it is in his knowledge that man has found his greatness and his happiness, the high superiority which he holds over the other animals who inhabit the earth with him, and consequently no ignorance is probably without loss to him, no error without evil … the particle and the planet are subject to the same laws, and what is learned of one will be known of the other … I bequeath the whole of my property … to the United States of America to found at Washington, under the name of the Smithsonian Institution, an establishment for the increase and diffusion of knowledge among men."

"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."

"Knowledge alone is the being of Nature, Giving a soul to her manifold features, Lighting through paths of the primitive darkness, The footsteps of Truth and the vision of Song."

"Knowledge comes, but wisdom lingers."

"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."

"For all the talk you hear about knowledge being such a wonderful thing, instinct is worth forty of it for real unerringness."

"We have not the reverent feeling for the rainbow that the savage has, because we know how it is made. We have lost as much as we gained by prying into that matter."

"Man's knowledge, save before his fellow man, Is ignorance—his widest wisdom folly."

"Knowledge, in truth, is the great sun in the firmament. Life and power are scattered with all its beams."

"Knowledge is the only fountain, both of the love and the principles of human liberty."

"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."

"Logic and sermons never convince, The damp of the night drives deeper into my soul. (Only what proves itself to every man and woman is so, Only what nobody denies is so.)"

"He who binds His soul to knowledge, steals the key of heaven."

"A man who knows how little he knows is well, a man who knows how much he knows is sick."

"Love and knowledge have one and the same goal, for both strive to overcome the separation in the elements of being and return to the point of their original unity.… To know an object means to negate the distance between it and consciousness; it means, in a certain sense, to become one with the object: cognitio nihil est aliud, quam Coitio quaedam cum suo cognobili. [Knowledge is nothing else than a kind of union with what is known.]"

"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."

""Knowledge," in the sense of information, means the working capital, the indispensable resources, of further inquiry; of finding out, or learning, more things. Frequently it is treated as an end in itself, and then the goal becomes to heap it up and display it when called for. This static, cold-storage ideal of knowledge is inimical to educative development."

"The notion that "applied" knowledge is somehow less worthy than "pure" knowledge, was natural to a society in which all useful work was performed by slaves and serfs, and in which industry was controlled by the models set by custom rather than by intelligence. Science, or the highest knowing, was then identified with pure theorizing, apart from all application in the uses of life; and knowledge relating to useful arts suffered the stigma attaching to the classes who engaged in them."

"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution."

"I want to know God's thoughts — the rest are mere details."

"The general policy of the past has been to drive, but the era of force must give way to that of knowledge, and the policy of the future will be to teach and to lead, to the advantage of all concerned."

"If a man empties his purse into his head no man can take it from him. An investment in knowledge pays the best interest."

"The fact is the sweetest dream that labor knows."

"I must know everything. I must penetrate the heart of his secret! I must become Caligari!"

"There are gems of wondrous brightness Ofttimes lying at our feet, And we pass them, walking thoughtless, Down the busy, crowded street. If we knew, our pace would slacken, We would step more oft with care, Lest our careless feet be treading To the earth some jewel rare."

"The only link between the verbal and objective world is exclusively structural, necessitating the conclusion that the only content of all 'knowledge' is structural. Now structure can be considered as a complex of relations, and ultimately as multi-dimensional order. From this point of view, all language can be considered as names for unspeakable entities on the objective level, be it things or feelings, or as names of relations. In fact... we find that an object represents an abstraction of a low order produced by our nervous system as the result of a sub-microscopic events acting as stimuli upon the nervous system."

"'Whatever you might say the object "is", well it is not.'"

"Without love the acquisition of knowledge only increases confusion and leads to self-destruction."

"Never was there a greater need for the diffusion of knowledge, for in the present ignorance of men there is a very real and imminent danger. We have in the immediate future the possibility of serious struggle; we have all the elements of a possible social upheaval, and we have no religion with sufficient hold upon the people to check what may develop into a wild and dangerous movement. As yet philosophy is the study of the very few only, and the science which has done so much for us, and has achieved so many triumphs, cannot stay the danger which threatens us. The only thing that can prevent it is the diffusion of knowledge, so that men shall understand what is really best for them and shall realize that nothing can ever be good for one which is against the interests of the whole. p. 333"

"A modern theory of knowledge which takes account of the relational as distinct from the merely relative character of all historical knowledge must start with the assumption that there are spheres of thought in which it is impossible to conceive of absolute truth existing independently of the values and position of the subject and unrelated to the social context."

"If you want knowledge, you must take part in the practice of changing reality."

"I hold all knowledge that is concerned with things that actually exist – all that is commonly called Science – to be of very slight value compared to the knowledge which, like philosophy and mathematics, is concerned with ideal and eternal objects, and is freed from this miserable world which God has made."

"The good life is one inspired by love and guided by knowledge."

"All definite knowledge — so I should contend — belongs to science; all dogma as to what surpasses definite knowledge belongs to theology. But between theology and science there is a No Man’s Land, exposed to attack by both sides; this No Man’s Land is philosophy."

"There is much pleasure to be gained from useless knowledge."

"Technical knowledge, we have seen, is susceptible of formulation in rules, principles, directions, maxims - comprehensively, in propositions. It is possible to write down technical knowledge in a book. Consequently, it does not surprise us that when an artist writes about his art, he writes only about the technique of his art. This is so, not because he is ignorant of what may be called the aesthetic element, or thinks it unimportant, but because what he has to say about that he has said already (if he is a painter) in his pictures, and he knows no other way of saying it. And the same is true when a religious man writes about his religion or a cook about cookery. And it may be observed that this character of being susceptible of precise formulation gives to technical knowledge at least the appearance of certainty: it appears to be possible to be certain about a technique. On the other hand, it is a characteristic of practical knowledge that it is not susceptible of formulation of this kind. Its normal expression is in a customary or traditional way of doing things, or, simply, in practice. And this gives it the appearance of imprecision and consequently of uncertainty, of being a matter of opinion, of probability rather than truth. It is, indeed, a knowledge that is expressed in taste or connoisseurship, lacking rigidity and ready for the impress of the mind of the learner. Technical knowledge can be learned from a book; it can be learned in a correspondence course. Moreover, much of it can be learned by heart, repeated by rote, and applied mechanically: the logic of the syllogism is a technique of this kind. Technical knowledge, in short, can be both taught and learned in the simplest meanings of these words. On the other hand, practical knowledge can neither be taught nor learned, but only imparted and acquired. It exists only in practice, and the only way to acquire it is by apprenticeship to a master - not because the master can teach it (he cannot), but because it can be acquired only by continuous contact with one who is perpetually practising it. In the arts and in natural science what normally happens is that the pupil, in being taught and in learning the technique from his master, discovers himself to have acquired also another sort of knowledge than merely technical knowledge, without it ever having been precisely imparted and often without being able to say precisely what it is. Thus a pianist acquires artistry as well as technique, a chess-player style and insight into the game as well as a knowledge of the moves, and a scientist acquires (among other things) the sort of judgement which tells him when his technique is leading him astray and the connoisseurship which enables him to distinguish the profitable from the unprofitable directions to explore."

"It would be easier to break up a theme of Beethoven with dissecting knife or acid than to break up the soul by methods of abstract thought. Nature-knowledge and man-knowledge have neither ways nor aims in common."

"Nur dem, der Glück verachtet, wird Erkenntnis."

"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."

"Under the world view possessed by medieval scholars, the path of learning was a path of self-deprecation. … An opposite conception comes in with Bacon’s “knowledge is power.” If the aim of knowledge is domination, it is hardly to be supposed that the possessors of knowledge will be indifferent to their importance. On the contrary, they begin to swell; the seek triumphs in the material world (knowledge being meanwhile necessarily degraded to skills) which inflate their egotism and self-consideration. Such is a brief history of how knowledge passes from a means of spiritual redemption to a basis for intellectual pride."

"One only begins to comprehend when one begins to stop trying to know."

"Knowledge is indivisible. When people grow wise in one direction, they are sure to make it easier for themselves to grow wise in other directions as well. On the other hand, when they split up knowledge, concentrate on their own field, and scorn and ignore other fields, they grow less wise — even in their own field."

"There's nothing you can know that isn't known Nothing you can see that isn't shown There's nowhere you can be that isn't where you're meant to be It's easy"

"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."

"Somewhere, something incredible is waiting to be known."

"The trouble with people is not that they don't know but that they know so much that ain't so."

"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."

"While knowledge is orderly and cumulative, information is random and miscellaneous."

"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."

"And by the way, it’s knowledge that moves mountains, you know, not faith."

"Knowledge makes people special. Knowledge enriches life itself."

"A man of knowledge lives by acting, not by thinking about acting... Thus a man of knowledge sweats and puffs and if one looks at him he is just like an ordinary man, except that the folly of his life is under his control."

"Knowledge about the process being modeled starts fairly low, then increases as understanding is obtained and tapers off to a high value at the end."

"Knowledge is a deadly friend, If no one sets the rules. The fate of all mankind I see, Is in the hands of fools."

"We should admit rather that power produces knowledge (and not simply by encouraging it because it serves power or by applying it because it is useful); that power and knowledge directly imply one another."

"There's no earthly way of knowing Which direction we are going There's no knowing where we're rowing Or which way the river's flowing Is it raining? Is it snowing? Is a hurricane a-blowing? Not a speck of light is showing So the danger must be growing Are the fires of hell a-glowing? Is the grisly reaper mowing? Yes, the danger must be growing 'Cause the rowers keep on rowing And they're certainly not showing Any signs that they are slowing!"

"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."

"Knowing is the task of Subjects, not of objects. It is as a subject, and only as such, that a man or woman can really know. In the learning process the only person who really learns is s/he who appropriates what is learned, who apprehends and thereby re-invents that learning; s/he who is able to apply the appropriated learning to concrete existential situations. On the other hand, the person who is filled by another with "contents" whose meaning s/he is not aware of, which contradict his or her way of being in the world, cannot learn because s/he is not challenged."

"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."

"Various attempts have been made in recent years to state necessary and sufficient conditions for someone's knowing a given proposition. The attempts have often been such that they can be stated in a form similar to the following: (a) S knows that P IFF (i) P is true, (ii) S believes that P, and (iii) S is justified in believing that P. ... These ... examples show that definition (a) does not state a sufficient condition for someone's knowing a given proposition."

"Nothing can be achieved without knowledge, and yet everything can be achieved just through a pure heart."

"The human sciences have to assume at least an equal responsibility in establishing the foundations of knowledge."

"I hold that every bit of definite knowledge has to have a mathematical aspect"

"Charles Hartshorne, "Charles Hartshorne, Philosophy," in interview with Steven Vita, Veery journal (1996)"

"No human mind can comprehend all the knowledge which guides the actions of society."

"Civilization enables us constantly to profit from knowledge which we individually do not possess and because each individual's use of his particular knowledge may serve to assist others unknown to him in achieving their ends that men as members of civilized society can pursue their individual ends so much more successfully than they could alone."

"But history may well remember this as a week for an act of lesser immediate impact, and that is the decision by the United States and the Soviet Union to seek concrete agreements on the joint exploration of space. Experience has taught us that an agreement to negotiate does not always mean a negotiated agreement. But should such a joint effort be realized, its significance could well be tremendous for us all. In terms of space science, our combined knowledge and efforts can benefit the people of all the nations: joint weather satellites to provide more ample warnings against destructive storms--joint communications systems to draw the world more closely together--and cooperation in space medicine research and space tracking operations to speed the day when man will go to the moon and beyond. But the scientific gains from such a joint effort would offer, I believe, less realized returns than the gains for world peace. For a cooperative Soviet-American effort in space science and exploration would emphasize the interests that must unite us, rather than those that always divide us. It offers us an area in which the stale and sterile dogmas of the cold war could be literally left a quarter of a million miles behind. And it would remind us on both sides that knowledge, not hate, is the passkey to the future--that knowledge transcends national antagonisms--that it speaks a universal language--that it is the possession not of a single class, or of a single nation or a single ideology, but of all mankind."

"We may be proud as a nation of our record in scientific achievement--but at the same time we must be impressed by the interdependence of all knowledge. I am certain that every scholar and scientist here today would agree that his own work has benefited immeasurably from the work of the men and women in other countries. The prospect of a partnership with Soviet scientists in the exploration of space opens up exciting prospects of collaboration in other areas of learning. And cooperation in the pursuit of knowledge can hopefully lead to cooperation in the pursuit of peace."

"No one who examines the modern world can doubt that the great currents of history are carrying the world away from the monolithic idea towards the pluralistic idea--away from communism and towards national independence and freedom. No one can doubt that the wave of the future is not the conquest of the world by a single dogmatic creed but the liberation of the diverse energies of free nations and free men. No one can doubt that cooperation in the pursuit of knowledge must lead to freedom of the mind and freedom of the soul."

"Beyond the drumfire of daily crisis, therefore, there is arising the outlines of a robust and vital world community, founded on nations secure in their own independence, and united by their allegiance to world peace. It would be foolish to say that this world will be won tomorrow, or the day after. The processes of history are fitful and uncertain and aggravating. There will be frustrations and setbacks. There will be times of anxiety and gloom. The specter of thermonuclear war will continue to hang over mankind; and we must heed the advice of Oliver Wendell Holmes of "freedom leaning on her spear" until all nations are wise enough to disarm safely and effectively. Yet we can have a new confidence today in the direction in which history is moving. Nothing is more stirring than the recognition of great public purpose. Every great age is marked by innovation and daring--by the ability to meet unprecedented problems with intelligent solutions. In a time of turbulence and change, it is more true than ever that knowledge is power; for only by true understanding and steadfast judgment are we able to master the challenge of history."

"All types of knowledge, ultimately mean self knowledge."

"When I speak of knowledge, as you know, I am speaking of that dark and true depth which understanding serves, waits upon, and makes accessible through language to ourselves and others. It is this depth within each of us that nurtures vision."

"Man's knowledge makes another leap through the test of practice. This leap is more important than the previous one. For it is this leap alone that can prove the correctness or incorrectness of the first leap in cognition, i.e., of the ideas, theories, policies, plans or measures formulated in the course of reflecting the objective external world. There is no other way of testing truth. Furthermore, the one and only purpose of the proletariat in knowing the world is to change it. Often, correct knowledge can be arrived at only after many repetitions of the process leading from matter to consciousness and then back to matter, that is, leading from practice to knowledge and then back to practice."

"I know that you believe you understand what you think I said, but I'm not sure you realize that what you heard is not what I meant."

"Penetrating so many secrets, we cease to believe in the unknowable. But there it sits nevertheless, calmly licking its chops."

"Each part of the mind sees only a little of what happens in some others, and that little is swiftly refined, reformulated and "represented." We like to believe that these fragments have meanings in themselves—apart from the great webs of structure from which they emerge—and indeed this illusion is valuable to us qua thinkers—but not to us as psychologists—because it leads us to think that expressible knowledge is the first thing to study."

"I think that asking “what's the point?” when referring to the contents of a study or research project can be indicative of a utilitarian, pragmatic, consumerist mindset. I believe that advanced civilizations should leave room for knowledge as a value in itself."

"What is the difference between merely knowing (or remembering, or memorizing) and understanding? ...A thing or idea seems meaningful only when we have several different ways to represent it–different perspectives and different associations. ...Then we can turn it around in our minds, so to speak: however it seems at the moment, we can see it another way and we never come to a full stop. In other words, we can 'think' about it. If there were only one way to represent this thing or idea, we would not call this representation thinking."

"How can the unknown merit reverence? In other words how can you revere that of which you are ignorant? At the same time, it would be ridiculous to propose that what we know merits reverence. What we know merits any one of a number of things, but it stands to reason reverence isn't one of them. In other words, apart from the known and the unknown, what else is there?"

"The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance. For this, indeed, is the main source of our ignorance — the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite."

"To gain knowledge, we must learn to ask the right questions; and to get answers, we must act, not wait for answers to occur to us."

"Let no one be deluded that a knowledge of the path can substitute Jor putting one foot in front of the other."

"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?"

"Knowledge is not eating, and we cannot expect to devour and possess what we mean. Knowledge is recognition of something absent; it is a salutation, not an embrace."

"Ideas are everywhere, but knowledge is rare."

"I shall maintain that there simply is no such thing as philosophical knowledge, nor any philosophical way of knowing anything, and defend the humble point that philosophy is indeed the love of wisdom."

"Knowing the theory of anything is contrasted with know-how in all the arts...Beethoven..Michelangelo..Shakespeare, all great exponents of know-how, probably knew how to manipulate their instruments to achieve the desired results long before they knew the theory of their art. Perhaps some of them never bothered to learn the theory. On the other hand, there are many who know the theory better than these, but who lack know-how....Although we acquire the skill of understanding words by experience, so that we know the correlations between them and things, between words and other words, and between words and feelings and actions, we do not do it by inductive reasoning. Nor must we think that we do it by deductive reasoning... In the main, words are cues rather than clues."

"Knowledge is in the end based on acknowledgement."

"People making bad choices ... and blame but themselves, the beginning reality tv show folks... glad we grew out of that, when you know better, you do better, right?"

"A deep consideration of the essence of knowledge should reveal how knowledge corresponds to the truth. ... Darkness reigns when knowledge is silent. ... Knowledge is a unique kind of property, indeed: you can share it with others, while still possessing it. ... There is a fascinating entanglement of science and knowledge, which is expressed as scientific knowledge."

"You can't manage knowledge — nobody can. What you can do is to manage the environment in which knowledge can be created, discovered, captured, shared, distilled, validated, transferred, adopted, adapted and applied."

"While knowledge is increasingly being viewed as a commodity or intellectual asset, there are some paradoxical characteristics of knowledge that are radically different from other valuable commodities. These knowledge characteristics include the following: • Using knowledge does not consume it. • Transferring knowledge does not result in losing it. • Knowledge is abundant, but the ability to use it is scarce. • Much of an organization’s valuable knowledge walks out the door at the end of the day."

"There may be things that are completely unknowable to us, so we must be careful not to treat the limits of our knowledge as sure guides to the limit of what there is."

"In Western society... [t]here are no more continents... little left to discover. I am, in part, an ant biologist... and I knew that much of the world of insects remains unknown. ...How ignorant are we? The question of what we know and do not know clung to me. ...In looking into the stories of biological discovery, I... began to find... a collection of scientists, often obsessive, usually brilliant, occasionally half-mad... Those individuals very often see the same things that other scientists see, but they pay more attention... and they focus on them to the point of exhaustion, and at the risk of the ridicule of their peers. ...[W]e are, before these discoveries, always more ignorant than we imagine ourselves to be. ...[W]e are repeatedly willing to imagine we have found most of what is left to discover. Before microbes were discovered, scientists were confident that insects were the smallest organisms. Before life was discovered at the bottom of the ocean, many scientists were confident that nothing lived deeper than three hundred fathoms. Once we made a tree of life that included four kingdoms (animals, plants, fungi, and s), we were confident that there would be no more major branches to reveal. ...We are again at a stage when we believe we have found most of what might be found, but we are wrong. ...[W]hole realms of life remain to be found. ...And even before a new realm or kind of life is found, we still have to explore the realms we have already discovered. Most species on Earth are not yet named. Most named species have not yet been studied. When we lived in small communities, hunting and gathering, we knew only the animals and plants around us, particularly those... useful or dangerous. Living on the thin green surface of our small planet in a universe full of stars, we are not so different today. The wild leaps up and more often than not we do not event know its name."

"Fortunately, in our time, we've learned more about the problems than in all preceding history. And with knowing comes caring."

"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."

"What we call knowledge does not and cannot have the purpose of producing representations of an independent reality, but instead has an adaptive function."

"Our brains are really not equipped to process events on the geologic scale—at least in reference to how we choose to live, or what we choose to do in the here and now."

"As Immanuel Kant pointed out long ago, learning to learn is one of the things that we cannot learn from experience. [see Kant 18th century quote above on à priori and à posteriori knowledge] ...So although sensations give us "occasions" to learn, this cannot be what makes us "able", to learn, because we first must have the additional knowledge that our brains would need, as Kant has said, to "produce representations" and then "to connect" them. Such additional knowledge would also include inborn ways to recognize correlations and other relations among sensations. I suspect that... our brains are already innately endowed with machinery to help us "to compare, to connect, or to separate" objects so that we can represent them as existing in space."

"It makes no sense to seek a single best way to represent knowledge—because each particular form of expression also brings its particular limitations. For example, logic-based systems are very precise, but they make it hard to do reasoning with analogies. Similarly, statistical systems are useful for making predictions, but do not serve well to represent the reasons why those predictions are sometimes correct."

"May I free myself from the labyrinth of knowledge"

"The importance of knowing nothing is underrated."

"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."

"I draw [a] distinction between knowledge and information. You can find information online very easily. Knowledge is another matter altogether. Now, this is not something new about the Internet [but] a basic feature of human life that while information is easy, knowledge is difficult. There has never been a shortage of mere data and opinion in human life. It’s a very old observation that the most ignorant people are usually full of opinions, while many of the most knowledgeable people are full of doubt. Other people are certainly sources of knowledge, but they are also sources of half-truths, confusion, misinformation, and lies. If we simply want information from others, it is easy to get; if we want knowledge in any strong sense of the word, it is very difficult."

"The acquisition of knowledge is the voyage of humanity, isn't it?"

"[[Game theory|[G]ame theory]] has already established itself as an essential tool in the , where it is widely regarded as a unifying language for investigating human behavior. Game theory's prominence in evolutionary biology builds a natural bridge between the life sciences and the behavioral sciences. And connections have been established between game theory and the two most prominent pillars of physics: and quantum theory. ...[M]any physicists, neuroscientists, and social scientists... are... pursuing the dream of a quantitative science of human behavior. Game theory is showing signs of... an increasing[ly] important role in that endeavor. It's a story of exploration along the shoreline separating the continent of knowledge from an ocean of ignorance... a story worth telling."

"The knowable world is incomplete if seen from any one point of view, incoherent if seen from all points of view at once, and empty if seen from nowhere in particular."

"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."

"The sucker’s trap is when you focus on what you know and what others don’t know, rather than the reverse."

"Sapiens did not forage only for food and materials. They foraged for knowledge as well."

"He who knows not, and knows not that he knows not, is a fool. Shun him. He who knows not, and knows that he knows not, is simple. Teach him. He who knows, and knows not that he knows, is asleep. Wake him. He who knows, and knows that he knows, is wise. Follow him."

"Men are four: He who knows not and knows not he knows not, he is a fool—shun him; He who knows not and knows he knows not, he is simple—teach him; He who knows and knows not he knows, he is asleep—wake him; He who knows and knows he knows, he is wise—follow him!"

"There are four kinds of people, three of which are to be avoided and the fourth cultivated: those who don't know that they don't know; those who know that they don't know; those who don't know that they know; and those who know that they know."

"He that hath knowledge spareth his words."

"Learn to say I do not know"

"If a man empties his purse into his head no one can take it away from him. An investment in knowledge always pays the best interest."

"Perplexity is the beginning of knowledge."

"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."

"They never open their mouths without subtracting from the sum of human knowledge."

"Give light and the people will find their own way."
