It is true, that 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.

knowledge

Knowledge is, indeed, that which, next to virtue, truly and essentially raises one man above another. It finishes one half of the human Soul. It makes Being pleasant to us, fills the mind with entertaining views, and administers to it a perpetual series of gratifications. It gives ease to solitude and gracefulness to retirement. It fills a publick station with suitable abilities, and adds a lustre to those who are in possession of them.

IGNORAMUS, n. A person unacquainted with certain kinds of knowledge familiar to yourself, and having certain other kinds that you know nothing about.

The need for a body of common knowledge and common reference does not disappear when a society is largely pluralistic, as ours has become. On the contrary, it grows more necessary, so that people of different origins and occupation may quickly find familiar ground and, as we say, speak a common language. It not only saves time and embarrassment, but it also ensures a kind of mutual confidence and good will. One is not addressing an alien, blank as a stone wall, but a responsive creature whose mind is filled with the same images, memories, and vocabulary as oneself.

Mistakes are, after all, the foundation of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not.
Don’t you believe ’em when they say that what you don’t know won’t hurt you. Biggest lie ever was. See it all and go your own way and nothing’ll hurt you. If what you see ain’t pretty, what’s the odds! See it anyway. Then next time you don’t have to look.

The Old Greek version of the Septuagint uses a word that translated out to "evil" or "wickedness" or "injustice". Later versions, particularly Theodotian's favored translation, used "knowledge" (Hebrew הַדָּֽעַת or Greek γνῶσις) [notes 1, 2, 3, 4].
Quoted by Francis Bacon as an epigraph on the frontispiece of his Instauratio Magna [The Great Instauration] (1620), in both English (as the King James Version) and Latin: "Multi pertransibunt & augebitur scientia."

The Ten Commandments that, as a teacher, I should wish to promulgate, might be set forth as follows:
- Do not feel absolutely certain of anything.
- Do not think it worth while to proceed by concealing evidence, for the evidence is sure to come to light.
- Never try to discourage thinking for you are sure to succeed.
- When you meet with opposition, even if it should be from your husband or your children, endeavour to overcome it by argument and not by authority, for a victory dependent upon authority is unreal and illusory.
- Have no respect for the authority of others, for there are always contrary authorities to be found.
- Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.
- Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
- Find more pleasure in intelligent dissent that in passive agreement, for, if you value intelligence as you should, the former implies a deeper agreement than the latter.
- Be scrupulously truthful, even if the truth is inconvenient, for it is more inconvenient when you try to conceal it.
- Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.

A little knowledge is said to be a dangerous thing, but it is not dangerous to the imagination. Knowledge is to the imagination what fuel is to flame. A little feeds it; a great deal extinguishes it.
If we turn away from knowledge and truth, we will not succeed. If we believe the worst and suspect the best, we alone will suffer. If we deny our progress, if we are against all of it, if we tear down our accomplishments, we will fill the world with sorrow, and we will blemish our own name with shame.
But if we are courageous and farsighted and farseeing, if we have no fear of the truth, if we seek only after light, then we and our children and our children’s children shall know the greatness of this wonderful, beautiful land we call America.Lyndon B.

CALVIN’S DAD: It’s funny … when I was a kid, I thought grown-ups never worried about anything. I trusted my parents to take care of everything, and it never occurred to me that they might not know how. I figured that once you grew up, you automatically knew what to do in any given scenario. I don’t think I would have been in such a hurry to reach adulthood if I’d know the whole thing was going to be ad-libbed.

Science doesn’t supply happiness; but neither does its lack. The same can be said of social utopias: they aren’t created by science, but neither does lack of science provide them. Science has cast up dangerous and cruel knowledge, which has been exploited for warfare and dictatorial power; but so have cultures so little gifted with scientists that they either make do with imported weapons or rely on clubs, axes, and daggers. Scientific information about our mistakes — for instance, that deforestation invites mud slides and deserts, that overfishing depletes fish stocks — doesn’t guarantee we will avoid such mistakes or correct them, but that is owing to failure to heed what science uncovers.

No desire is more natural than the desire for knowledge. We assay all the means that can lead us to it. When reason fails us we make use of experience. Experience is a weaker and less dignified means: but truth is so great a matter that we must not disdain any method that leads us to it.
[Il n’est desir plus naturel que le desir de cognoissance. Nous essayons tous les moyens qui nous y peuvent mener. Quand la raison nous faut, nous y employons l’experience.

The question is then how can we decide what anybody in the ancient world said. We can’t. We wish we could. It would be nice if we could. You would like to think that because you can go to the store and buy an edition of Plato that you are actually reading Plato, but the problem is that we just do not have the kind of evidence that we need in order to establish what ancient authors actually wrote. In some cases, we have all these data, and sometimes we have just one manuscript. Sometimes we have a manuscript that was written two-thousand years later, and that’s it! So, as much as we would like to be able to say we know what ancient authors actually wrote, we often just do not know.

Real education precisely consists in the fact that we see beyond the symbols and the mere machinery of the age in which we find ourselves: education precisely consists in the realization of a permanent simplicity that abides behind all civilizations, the life that is more than meat, the body that is more than raiment.

It is supposed to be true that those who do not know history are doomed to repeat it. I don’t believe knowing can save us. What is constant in history is greed and foolishness and a love of blood, and this is a thing that even God — who knows all that can be known — seems powerless to change.
The mind is formed by the knowledge and the direction of ideas it receives and the guidance it is given. Great things alone can make a great mind, and petty things will make a petty mind unless a man rejects them as completely alien.

Those long chains composed of very simple and easy reasonings, which geometers customarily use to arrive at their most difficult demonstrations, had given me occasion to suppose that all the things which come within the scope of human knowledge are interconnected in the same way. And I thought that, provided we refrain froma ccepting anything as true which is not, and always keep to the order required for deducing one thing from another, there can be nothing too remote to be reached in the end or too well hidden to be discovered.
[Ces longues chaînes de raisons, toutes simples et faciles, dont les géomètres ont coutume de se servir pour parvenir à leurs plus difficiles démonstrations, m’avoient donné occasion de m’imaginer que toutes les choses qui peuvent tomber sous la connoissance des hommes s’entresuivent en même façon, et que, pourvu seulement qu’on s’abstienne d’en recevoir aucune pour vraie qui ne le soit, et qu’on garde toujours l’ordre qu’il faut pour les déduire les unes des autres, il n’y en peut avoir de si éloignées auxquelles enfin on ne parvienne, ni de si cachées qu’on ne découvre.]

[Newcombe ed. (1649)]The long chains of simple and easy reasonings by means of which geometers are accustomed to reach the conclusions of their most difficult demonstrations, had led me to imagine that all things, to the knowledge of which man is competent, are mutually connected in the same way, and that there is nothing so far removed from us as to be beyond our reach, or so hidden that we cannot discover it, provided only we abstain from accepting the false for the true, and always preserve in our thoughts the order necessary for the deduction of one truth from another.
[tr. Veitch (1850)]Those long chains of reasoning, simple and easy as they are of which geometricians make use in order to arrive at the most difficult demonstrations, had caused me to imagine that all those things which fall under the cognizance of man might very likely be mutually related in the same fashion; and that, provided only that we abstain from receiving anything as true which is not so, and always retain the order which is necessary in order to deduce the one conclusion from the other, there can be nothing so remote that we cannot reach to it, nor to recondite that we cannot discover it.
[tr. Haldane & Ross (1911)]These long chains of perfectly simple and easy reasonings by means of which geometers are accustomed to carry out their most difficult demonstrations had led me to fancy that everything that can fall under human knowledge forms a similar sequence; and that so long as we avoid accepting as true what it not so, and always preserve the right order for deduction of one thing from another, there can be nothing too remote to be reached in the end, or too well hidden to be discovered.

In the course of my travels I remarked that all those whose opinions are decidedly repugnant to ours are not in that account barbarians and savages, but on the contrary that many of these nations make an equally good, if not better, use of their reason than we do. I took into account also the very different character which a person brought up from infancy in France or Germany exhibits, from that which, with the same mind originally, this individual would have possessed had he lived always among the Chinese or with savages, and the circumstance that in dress itself the fashion which pleased us ten years ago, and which may again, perhaps, be received into favor before ten years have gone, appears to us at this moment extravagant and ridiculous. I was thus led to infer that the ground of our opinions is far more custom and example than any certain knowledge.
[Et depuis, en voyageant, ayant reconnu que tous ceux qui ont des sentiments fort contraires aux nôtres ne sont pas pour cela barbares ni sauvages, mais que plusieurs usent autant ou plus que nous de raison; et ayant considéré combien un même homme, avec son même esprit, étant nourri dès son enfance entre des Français ou des Allemands, devient différent de ce qu’il seroit s’il avoit toujours vécu entre des Chinois ou des cannibales, et comment, jusques aux modes de nos habits, la même chose qui nous a plu il y a dix ans, et qui nous plaira peut-être encore avant dix ans, nous semble maintenant extravagante et ridicule; en sorte que c’est bien plus la coutume et l’exemple qui nous persuade, qu’aucune connaissance certaine.]

So that it’s much more Custome and Example which perswades us, then any assured knowledg.
[tr. Newcombe ed. (1649)]I further recognized in the course of my travels that all those whose sentiments are very contrary to ours are yet not necessarily barbarians or savages, but may be possessed of reason in as great or even a greater degree than ourselves. I also considered how very different the self-same man, identical in mind and spirit, may have become, according as he is brought up from childhood amongst the French or Germans, or has passed his whole life amongst Chinese or cannibals. I likewise noticed how even in the fashions of one's clothing the same thing that pleased us ten years ago, and which will perhaps please us once again before ten years are passed, seems at the present time extravagant and ridiculous. I thus concluded that it is much more custom and example that persuade us than any certain knowledge.
[tr. Haldane & Ross (1911)]Since then I have recognized through my travels that those with views quite contrary to ours are not on that account barbarians or savages, but that many of them make use of reason as much or more than we do. I thought, too, how the same man, with the same mind, if brought up from infancy among the French or Germans, develops otherwise than he would if he had always lived among the Chinese or cannibals; and how, even in our fashions of dress, the very thing that pleased us ten years ago, and will perhaps please us again ten years hence, now strikes us as extravagant and ridiculous. Thus it is custom and example that persuade us, rather than any certain knowledge.

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.

The rule which should guide us in such cases is simple and obvious enough: that the aggregate testimony of our neighbours is subject to the same conditions as the testimony of any one of them. Namely, we have no right to believe a thing true because everybody says so unless there are good grounds for believing that some one person at least has the means of knowing what is true, and is speaking the truth so far as he knows it. However many nations and generations of men are brought into the witness-box, they cannot testify to anything which they do not know. Every man who has accepted the statement from somebody else, without himself testing and verifying it, is out of court; his word is worth nothing at all. And when we get back at last to the true birth and beginning of the statement, two serious questions must be disposed of in regard to him who first made it: was he mistaken in thinking that he knew about this matter, or was he lying?

O’Brien knew everything. A thousand times better than Winston, he knew what the world was really like, in what degradation the mass of human beings lived and by what lies and barbarities the Party kept them there. He had understood it all, weighed it all, and it made no difference: all was justified by the ultimate purpose. What can you do, thought Winston, against the lunatic who is more intelligent than yourself, who gives your arguments a fair hearing and then simply persists in his lunacy?

Now if of the things we do there is an end which we wish for its own sake […] then clearly this end would be good and the highest good. Will not knowledge of it, then, have a great influence on our way of life, and would we not as a consequence be more likely to attain the desired end, like archers who have a mark to aim at? If so, then we should try to grasp, in outline at least, what that end is and to which of the sciences or faculties it belongs.

(Source (Greek)). Alternate translations:Since then of all things which may be done there is some one End which we desire for its own sake, [...] this plainly must be the Chief Good, i.e. the best thing of all. Surely then, even with reference to actual life and conduct, the knowledge of it must have great weight; and like archers, with a mark in view, we shall be more likely to hit upon what is right: and if so, we ought to try to describe, in outline at least, what it is and of which of the sciences and faculties it is the End.
[tr. Chase (1847)]If then there be some one end of all that we do, for which we wish for its own sake [...] it is evident that this end will be the chief and supreme good. Surely then a scientific knowledge of it will have a critical influence upon our lives, and will make us, like bowmen who have a mark at which to aim, all the more likely to hit upon that which is good. And if this be so, we must endeavour to describe it at least in outline, and to say of what science or of what art it is the province.
[tr. Williams (1869)]If it is true that in the sphere of action there is an end which we wish for its own sake [...] it is clear this will be the good or the supreme good. Does it not follow then that the knowledge of this supreme good is of great importance for the conduct of life, and that, if we know it, we shall be like archers who have a mark at which to aim, we shall have a better chance of attaining what we want? But, if this is the case, we must endeavor to comprehend, at least in outline, its nature, and the science or faculty to which it belongs.
[tr. Welldon (1892), ch. 1]If then in what we do there be some end which we wish for on its own account, [...] this evidently will be the good or the best of all things. And surely from a practical point of view it much concerns us to know this good; for then, like archers shooting at a definite mark, we shall be more likely to attain what we want. If this be so, we must try to indicate roughly what it is, and first of all to which of the arts or sciences it belongs.
[tr. Peters (1893)]If, then, there is some end of the things we do, which we desire for its own sake [...] clearly this must be the good and the chief good. Will not the knowledge of it, then, have a great influence on life? Shall we not, like archers who have a mark to aim at, be more likely to hit upon what is right? If so, we must try, in outline at least, to determine what it is, and of which of the sciences or capacities it is the object.
[tr. Ross (1908)]If therefore among the ends at which our actions aim there be one which we will for its own sake [...] it is clear that this one ultimate End must be the Good, and indeed the Supreme Good. Will not then a knowledge of this Supreme Good be also of great practical importance for the conduct of life? Will it not better enable us to attain our proper object, like archers having a target to aim at? If this be so, we ought to make an attempt to determine at all events in outline what exactly this Supreme Good is, and of which of the sciences or faculties it is the object.
[tr. Rackham (1934)]If, then, there is some end of things doable in action that we wish for because of itself, [...] it is clear that this will be the good -- that is, the best good. Hence regarding our life as well, won't knowing the good have great influence and -- like archers with a target -- won't we be better able to hit what we should? If so, we should try to grasp in outline, at least, what the good is and to which of the sciences or capacities it properly belongs.
[tr. Reeve (1948)]So if what is done has some end that we want for its own sake [...] then clearly this will be the good, indeed the chief good. surely, then, knowledge of the good must be very important for our lives? And if, like archers, we have a target, are we not more likely to hit the right mark? If so, we must try at least roughly to comprehend what it is and which science of faculty is concerned with it.
[tr. Crisp (2000)]If, therefore, there is some end of our actions that we wish for on account of itself, [...] clearly this would be the good, that is, the best. And with a view to our life, then, is not the knowledge of this good of greater weight, and would we not, like archers in possession of a target, better hit on what is needed? If this is so, then one must try to grasp, in outline at least, whatever it is and to which of the sciences or capacities it belongs.

No fact in the world is instant, infinitesimal and ultimate, a single mark. There are, I hold, no atomic facts. In the language of science, every fact is a field — a crisscross of implications, those that lead to it and those that lead from it. We condense the laws around concepts. Science takes its coherence, its intellectual and imaginative strength together, from the concepts at which its laws cross, like knots in a mesh.

I am an atheist, out and out. It took me a long time to say it. I’ve been an atheist for years and years, but somehow I felt it was intellectually unrespectable to say one was an atheist, because it assumed knowledge that one didn’t have. Somehow it was better to say one was a humanist or an agnostic. I finally decided that I’m a creature of emotion as well as of reason. Emotionally I am an atheist. I don’t have the evidence to prove that God doesn’t exist, but I so strongly suspect he doesn’t that I don’t want to waste my time.

Knowledge is happiness, because to have knowledge — broad, deep knowledge — is to know true ends from false, and lofty things from low. To know the thoughts and deeds that have marked man’s progress is to feel the great heart-throbs of humanity through the centuries; and if one does not feel in these pulsations a heavenward striving, one must indeed be deaf to the harmonies of life.

Ardent desire for knowledge, in fact, is the one motive attracting and supporting investigators in their efforts; and just this knowledge, really grasped and yet always flying before them, becomes at once their sole torment and their sole happiness …. A man of science rises ever, in seeking truth; and if he never finds it in its wholeness, he discovers nevertheless very significant fragments; and these fragments of universal truth are precisely what constitutes science.
The evil that is in the world always comes of ignorance, and good intentions may do as much harm as malevolence, if they lack understanding. On the whole men are more good than bad; that, however, isn’t the real point. But they are more or less ignorant, and it is this that we call vice or virtue; the most incorrigible vice being that of an ignorance which fancies it knows everything and therefore claims for itself the right to kill. There can be no true goodness, nor true love, without the utmost clear-sightedness.

And whereas sense and memory are but knowledge of fact, which is a thing past and irrevocable, science is the knowledge of consequences, and dependence of one fact upon another; by which, out of that we can presently do, we know how to do something else when we will, or the like, another time: because when we see how anything comes about, upon what causes, and by what manner; when the like causes come into our power, we see how to make it produce the like effects.

Experience of the world may be looked upon as a kind of text, to which reflection and knowledge form the commentary. Where there is great deal of reflection and intellectual knowledge, and very little experience, the result is like those books which have on each page two lines of text to forty lines of commentary. A great deal of experience with little reflection and scant knowledge, gives us books like those of the editio Bipontina where there are no notes and much that is unintelligible.

For there is no comparison between that which we may lose by not trying and by not succeeding; since by not trying we throw away the chance of an immense good; by not succeeding we only incur the loss of a little human labour. But as it is, it appears to me from what has been said, and also from what has been left unsaid, that there is hope enough and to spare, not only to make a bold man try, but also to make a sober-minded and wise man believe.
[Non enim res pari periculo non tentatur, et no succedit; cum in illo ingentis boni, in hoc exiguae humanae operae, jactura vertatur. Verum ex dictis, atque etiam ex non dictis, visum est nobis spei abunde subesse, non tantum homini strenuo ad experiendum, sed etiam prudenti et sobrio ad credendum.]

(Source (Latin)). Alternate translations:For the risk attending want of success is not to be compared with that of neglecting the attempt; the former is attended with the loss of a little human labour, the latter with that of an immense benefit. For these and other reasons, it appears to us that there is abundant ground to hope, and to induce not only those who are sanguine to make experiment, but even those who are cautious and sober to give their assent.
[tr. Wood (1831)]For it is not a case where there is an equal risk in not trying and not succeeding; since in the former instance we risk a huge advantage; in the latter a little human labour is thrown away. But from what has been said, and also from what has not been said, it seems to us that there is abundant ground of hope, not only to justify a stout-hearted man in trying, but even a prodent and sober man in believing.
[tr. Johnson (1859)]For the danger of not trying and the danger of not succeeding are not equal, since the former risks the loss of great good, the latter of a little human effort. But from what we have said and from other things which we have not said, it has seemed to us that we have abundance of hope, whether we are men who press forward to meet new experiences, or whether we are careful and slow to believe.
[tr. Silverthorne (2000) "The Great Renewal"]The loss that may come from not trying is much greater than what may come from trying and not succeeding: by not trying we throw away the chance of an immense good; by not succeeding we only incur the loss of a little human labour. But from what I have said (and from some things that I haven’t said) it seems to me that there is more than enough hope not only to get a vigorous man to try but also to make a sober-minded and wise man believe that he will succeed.

If the Party could thrust its hand into the past and say of this or that event, it never happened — that, surely, was more terrifying than mere torture and death? The Party said that Oceania had never been in alliance with Eurasia. He, Winston Smith, knew that Oceania had been in alliance with Eurasia as short a time as four years ago. But where did that knowledge exist? Only in his own consciousness, which in any case must soon be annihilated. And if all others accepted the lie which the Party imposed — if all records told the same tale — then the lie passed into history and became truth. “Who controls the past,” ran the Party slogan, “controls the future: who controls the present controls the past.”

Sometimes paraphrased, "He who controls the past controls the future. He who controls the present controls the past."
The saying that a little knowledge is a dangerous thing is, to my mind, a very dangerous adage. If knowledge is real and genuine, I do not believe that it is other than a very valuable possession, however infinitesimal its quantity may be. Indeed, if a little knowledge is dangerous, where is the man who has so much as to be out of danger?
A little learning is a dangerous thing;
Drink deep, or taste not the Pierian Spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again.Alexander Pope (1688-1744) English poet
“An Essay on Criticism,” Part 2, ll. 15-18 (1711)

In Greek mythology, the Pierian Spring was sacred to the Muses, representing the metaphorical source of knowledge.
The first line is more commonly paraphrased as "A little knowledge is a dangerous thing."
To be born enlightened: that is highest. To study and so become enlightened: that is next. To feel trapped and so study: that is third. To feel trapped and never study: that is the level of the common people, the lowest level.

(Source)
Brooks says this was interpolated into Book 16 at the time of Book 18. (Source (Chinese)). Alternate translations:Those who are born with the possession of knowledge are the highest class of men. Those who learn, and so, readily, get possession of knowledge, are the next. Those who are dull and stupid, and yet compass the learning, are another class next to these. As to those who are dull and stupid and yet do not learn; -- they are the lowest of the people
[tr. Legge (1861), sec. 2]They whose knowledge comes by birth are of all men the first (in understanding); they to whom it comes by study are next; men of poor intellectual capacity, who yet study, may be added as a yet inferior class; and lowest of all are they who are poor in intellect and never learn.
[tr. Jennings (1895)]The highest class of men are those who are born with a natural understanding. The next class are those who acquire understanding by study and application. There are others again who are born naturally dull, but who yet by strenuous efforts, try to acquire understanding: such men may be considered the next class. Those who are born naturally dull and yet will not take the trouble to acquire understanding: such men are the lowest class of the people.
[tr. Ku Hung-Ming (1898)]Those who have innate wisdom take the biggest rank. Those who acquire it by study rank next. Those who learn despite natural limitations come next. But those who are of limited ability and yet will not learn, -- these form the lowest class of men.
[tr. Soothill (1910)]Those who know instinctively (as at birth) are the highest; those who study and find out, come next; those who are hampered and study come next. Those who are boxed in and do not study constitute the lowest people.
[tr. Pound (1933)]Best are those who are born wise. Next are those who become wise by learning. After come those who have to toil painfully in order acquire learning. Finally, to the lowest class of the common people belong those who toil painfully without ever managing to learn.
[tr. Waley (1938)]Those born with an understanding of the universe belong to the highest type of humanity. Those who understand it as the result of study come second. Those who study it with great difficulty come third. Because, owing to the difficulty, they do not study, the people come last.
[tr. Ware (1950)]Those who are born with knowledge are the highest. Next come those who attain knowledge through stud. Next again come those who turn to study after having been vexed by difficulties. The common people, in so far as they make no effort to study even after having been vexed by difficulties, are the lowest.
[tr. Lau (1979)]Those who know things from birth come first; those who know things from study come next; those who study things although the find them difficult come next to them; and those who do not study because they find things difficult, that is to say the common people, come last.
[tr. Dawson (1993)]Those who have innate knowledge are the highest. Next come those who acquire knowledge through learning. Next again come those who learn through the trials of life. Lowest are the common people who go through the trials of life without learning anything.
[tr. Leys (1997)]Those who know it at birth belong to the highest category; those who know it through learning belong to the second category; those hwo learn it when baffled belong to the third category; those who do not learn even when baffled -- such people belong to the lowest category.
[tr. Huang (1997)]It is the first class that one gets the knowledge because of one's innateness, it is the second class that one gets the knowledge because of one's studying, it is the third class that one gets studying because of one's encountering the difficulty, and it is under the class that one who does not study even if one encounters difficulties.
[tr. Cai/Yu (1998), #435]Knowledge (zhi 知) acquired through a natural propensity for it is its highest level; knowledge acquired through study is the next highest; something learned in response to difficulties encountered is again the next highest. But those among the common people who do not learn even when vexed with difficulties -- they are at the bottom of the heap.
[tr. Ames/Rosemont (1998)]Those who know from birth are the highest, those who know it from study are next, those who despite difficulties study it are next after that. Those who in difficulties do not study: these are the lowest.
[tr. Brooks/Brooks (1998)]Those who are born understanding it are the best; those who come to understand it through learning are second. Those who find it difficult to understand and yet persist in their studies come next. People who find it difficult to understand but do not even try to learn are the worst of all.
[tr. Slingerland (2003)]Those born with understanding rank highest. Those who study and gain understanding come next. Those who face difficulties and yet study—they are next. Those who face difficulties but never study—they are the lowest type of people.
[tr. Watson (2007)]Those who are born with knowledge are at the top. Next are those who acquire knowledge through learning. Behind them are those who have difficulties [absorbing knowledge] but are still determined to learn. And at the bottom are people who have difficulties [absorbing knowledge] and do not even attempt to learn.

This appears to be the source of the following aphorism frequently attributed to Confucius, and recorded in James Wood, ed., Dictionary of Quotations (1893):By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.
For more discussion of that Wood "translation":
The degree of one’s emotions varies inversely with one’s knowledge of the facts — the less you know the hotter you get.

This may be the source of an attributed Billings quote I cannot find in his writings: "Faith was given to man to lengthen out his reason."
The possession of facts is knowledge; the use of them is wisdom; the choice of them, education. Knowledge is not power but riches, and like them, has its value in spending.
“From what I remember,” replied Crowley, thoughtfully, “– and we were never actually on what you might call speaking terms — He wasn’t exactly one for a straight answer. In fact, in fact, He’d never answer at all. He’d just smile, as if He knew something that you didn’t.”
