Original: Para qué andar con medias tintas, los animales saben mucho más que las personas, ante todo porque sienten con más libertad que la mayoría de estas y, por ello, como dice Kafka, son poseedores de todo el conocimiento acerca de esta vida. Solo que son muy humildes para hacer gala de ello.

“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.”

Avicenna (980–1037) medieval Persian polymath, physician, and philosopher

"On Medicine, (c. 1020) http://www.fordham.edu/halsall/source/1020Avicenna-Medicine.html Context: 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.

“Where is the wisdom we have lost in knowledge?
Where is the knowledge we have lost in infomation?”

T.S. Eliot (1888–1965) 20th century English author

Choruses from The Rock (1934)
Variant: Where is the Life we have lost in living?
Where is the wisdom we have lost in knowledge?
Where is the knowledge we have lost in information?
Context: O perpetual revolution of configured stars,
O perpetual recurrence of determined seasons,
O world of spring and autumn, birth and dying!
The endless cycle of idea and action,
Endless invention, endless experiment,
Brings knowledge of motion, but not of stillness;
Knowledge of speech, but not of silence;
Knowledge of words, and ignorance of The Word.
All our knowledge brings us nearer to our ignorance,
All our ignorance brings us nearer to death,
But nearness to death no nearer to God.
Where is the Life we have lost in living?
Where is the wisdom we have lost in knowledge?
Where is the knowledge we have lost in information?
The cycles of Heaven in twenty centuries
Brings us farther from God and nearer to the Dust.

“As there are misanthropists, or haters of men, there are also misologists or haters of ideas, and both spring from the same cause, which is ignorance of the world. Misanthropy arises from too great confidence of inexperience; you trust a man and think him altogether true and good and faithful, and then in a little while he turns out to be false and knavish; and then another and another, and when this has happened several times to a man, especially within the circle of his most trusted friends, as he deems them, and he has often quarreled with them, he at last hates all men, and believes that no one has any good in him at all. …The reason is that a man, having to deal with other men, has no knowledge of them; for if he had knowledge he would have known the true state of the case, that few are the good and few the evil, and that the great majority are in the interval between them.”

“Wisdom is a perfection of knowledge acquired through experience.”

Mwanandeke Kindembo (1996) Congolese author

Perfection, Wisdom

“So many people are most miserable these days.
The reason they find it so difficult to be happy is that they always view the past to be better than it was, the present dramatically worse than it is, and the future less resolute than it will be.
The idea of happiness is foreign to them.
Is this not something that is innate because babies are born with
"tabula rasa" which refers to the epistemological idea that individuals are born without built-in mental content and that therefore all knowledge comes from experience or perception. However I don't disagree with the doctrine of Innatism which holds that the mind is born already in possession of certain knowledge.
A smile, for instance is natural and innate!
So it is a combination of the two schools of thought.”

“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.”

Meister Eckhart (1260–1328) German theologian

Sermon IV : True Hearing
Meister Eckhart’s Sermons (1909)
Context: The man who abides in the will of God wills nothing else than what God is, and what He wills. If he were ill he would not wish to be well. If he really abides in God's will, all pain is to him a joy, all complication, simple: yea, even the pains of hell would be a joy to him. He is free and gone out from himself, and from all that he receives, he must be free. If my eye is to discern colour, it must itself be free from all colour. 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.

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

John Locke (1632–1704) English philosopher and physician

As quoted in "Hand Book : Caution and Counsels" in The Common School Journal Vol. 5, No. 24 (15 December 1843) by Horace Mann, p. 371
Context: This is that which I think great readers are apt to be mistaken in; those who have read of everything, are thought to understand everything too; but it is not always so. Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections; unless we chew them over again, they will not give us strength and nourishment.

“Human knowledge is not (or does not follow) a straight line, but a curve, which endlessly approximates a series of circles, a spiral. Any fragment, segment, section of this curve can be transformed (transformed one-sidedly) into an independent, complete, straight line, which then (if one does not see the wood for the trees) leads into the quagmire, into clerical obscurantism (where it is anchored by the class interests of the ruling classes).”

“I like spring, but it is too young. I like summer, but it is too proud. So I like best of all autumn, because its leaves are a little yellow, its tone mellower, its colours richer, and it is tinged a little with sorrow and a premonition of death. Its golden richness speaks not of the innocence of spring, nor of the power of summer, but of the mellowness and kindly wisdom of approaching age. It knows the limitations of life and is content. From a knowledge of those limitations and its richness of experience emerges a symphony of colours, richer than all, its green speaking of life and strength, its orange speaking of golden content and its purple of resignation and death.”

“The. manager must never be lacking in knowledge of the special profession which is characteristic of the undertaking: the technical profession in industry, commercial in commerce, political in the State, military in the Army, religious in the Church, medical in the hospital, teaching in the school, etc. The technical function has long been given the degree of importance which is its due, and of which we must not deprive it, but the technical function by itself cannot endure the successful running of a business; it needs the help of the other essential functions and particularly of that of administration.

“Endurance is composed of four attributes: eagerness, fear, piety and anticipation (of death). so whoever is eager for Paradise will ignore temptations; whoever fears the fire of Hell will abstain from sins; whoever practices piety will easily bear the difficulties of life and whoever anticipates death will hasten towards good deeds.
Conviction has also four aspects to guard oneself against infatuations of sin; to search for explanation of truth through knowledge; to gain lessons from instructive things and to follow the precedent of the past people, because whoever wants to guard himself against vices and sins will have to search for the true causes of infatuation and the true ways of combating them out and to find those true ways one has to search them with the help of knowledge, whoever gets fully acquainted with various branches of knowledge will take lessons from life and whoever tries to take lessons from life is actually engaged in the study of the causes of rise and fall of previous civilizations.
Justice also has four aspects depth of understanding, profoundness of knowledge, fairness of judgment and dearness of mind; because whoever tries his best to understand a problem will have to study it, whoever has the practice of studying the subject he is to deal with, will develop a clear mind and will always come to correct decisions, whoever tries to achieve all this will have to develop ample patience and forbearance and whoever does this has done justice to the cause of religion and has led a life of good repute and fame.
Jihad is divided into four branches: to persuade people to be obedient to Allah; to prohibit them from sin and vice; to struggle (in the cause of Allah) sincerely and firmly on all occasions and to detest the vicious. Whoever persuades people to obey the orders of Allah provides strength to the believers; whoever dissuades them from vices and sins humiliates the unbelievers; whoever struggles on all occasions discharges all his obligations and whoever detests the vicious only for the sake of Allah, then Allah will take revenge on his enemies and will be pleased with Him on the Day of Judgment.”

“I can better understand the inert blindness & defiant ignorance of the reactionaries from having been one of them. I know how smugly ignorant I was—wrapped up in the arts, the natural (not social) sciences, the externals of history & antiquarianism, the abstract academic phases of philosophy, & so on—all the one-sided standard lore to which, according to the traditions of the dying order, a liberal education was limited. God! the things that were left out—the inside facts of history, the rational interpretation of periodic social crises, the foundations of economics & sociology, the actual state of the world today … & above all, the habit of applying disinterested reason to problems hitherto approached only with traditional genuflections, flag-waving, & callous shoulder-shrugs! All this comes up with humiliating force through an incident of a few days ago—when young Conover, having established contact with Henneberger, the ex-owner of WT, obtained from the latter a long epistle which I wrote Edwin Baird on Feby. 3, 1924, in response to a request for biographical & personal data. Little Willis asked permission to publish the text in his combined SFC-Fantasy, & I began looking the thing over to see what it was like—for I had not the least recollection of ever having penned it. Well …. I managed to get through, after about 10 closely typed pages of egotistical reminiscences & showing-off & expressions of opinion about mankind & the universe. I did not faint—but I looked around for a 1924 photograph of myself to burn, spit on, or stick pins in! Holy Hades—was I that much of a dub at 33 … only 13 years ago? There was no getting out of it—I really had thrown all that haughty, complacent, snobbish, self-centred, intolerant bull, & at a mature age when anybody but a perfect damned fool would have known better! That earlier illness had kept me in seclusion, limited my knowledge of the world, & given me something of the fatuous effusiveness of a belated adolescent when I finally was able to get around more in 1920, is hardly much of an excuse. Well—there was nothing to be done … except to rush a note back to Conover & tell him I'd dismember him & run the fragments through a sausage-grinder if he ever thought of printing such a thing! The only consolation lay in the reflection that I had matured a bit since '24. It's hard to have done all one's growing up since 33—but that's a damn sight better than not growing up at all.”

“Belief and work, knowledge and action are one and the same thing.”

Paracelsus (1493–1541) Swiss physician and alchemist

Paracelsus - Doctor of our Time (1992)

“When a man sought knowledge, it would not be long before it could be seen in his humbleness, his sight, upon his tongue and his hands, in his prayer, in his speech and in his disinterest (zuhd) in worldly allurements. And a man would acquire a portion of knowledge and put it into practice, and it would be better for him than the world and all it contains – if he owned it he would give it in exchange for the hereafter.”

Hasan al-Basri (642–728) Iranian Sufi Saint

Quoted in Ibn Al-Mubârak, Al-Zuhd wa Al-Raqâ`iq Vol.1 p. 156.

“When Adam and Eve realize they're naked is that same moment they realize the difference between good and evil. What's the relationship between consciousness, knowledge of nakedness, and knowledge of good and evil? When you know that you're vulnerable, and they also developed a knowledge of death so there's deep knowledge of vulnerability, and they get embarrassed about that and they cover themselves up. So that's culture. So it's a very profound shock when they come to recognize that they're naked. It even causes Adam to run and hide from God. Then they develop the knowledge of good and evil. This is about how human beings have this peculiar capacity that no other creatures have. I know how I can be hurt, because I am aware of my own limitations – painfully aware. And now, because I know how I can be hurt, I know how you can be hurt. And I can take advantage of that. And that's how evil enters the world. It gives people another attribute of divinity, knowing the difference between good and evil. The cosmos switches when that self-consciousness manifests itself, and that's when the possibility of evil enters the world.”

“Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.' The friction which results from ignorance… can be reduced only by the spread of knowledge and the unification of the heterogeneous elements of humanity. No effort could be better spent.”

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

William Cowper The Task

Source: The Task (1785), Book VI, Winter Walk at Noon, Line 92.
Context: Knowledge, a rude unprofitable mass,
The mere materials with which wisdom builds,
Till smoothed and squared and fitted to its place,
Does but encumber whom it seems to enrich.
Knowledge is proud that he has learned so much;
Wisdom is humble that he knows no more.
Books are not seldom talismans and spells.

Where knowledge is free”

Gitanjali http://www.spiritualbee.com/gitanjali-poems-of-tagore/ (1912) Context: Where the mind is without fear and the head is held high Where knowledge is free Where the world has not been broken up into fragments By narrow domestic walls Where words come out from the depth of truth Where tireless striving stretches its arms towards perfection Where the clear stream of reason has not lost its way Into the dreary desert sand of dead habit Where the mind is led forward by thee Into ever-widening thought and action Into that heaven of freedom, my Father, let my country awake.

“For the things of this world cannot be made known without a knowledge of mathematics.”

Roger Bacon book Opus Majus

Cited in: Opus majus: A translation by Robert Belle Burke. Vol 1 (1962). p. 128
Opus Majus, c. 1267
Context: For the things of this world cannot be made known without a knowledge of mathematics. For this is an assured fact in regard to celestial things, since two important sciences of mathematics treat of them, namely theoretical astrology and practical astrology. The first … gives us definite information as to the number of the heavens and of the stars, whose size can be comprehended by means of instruments, and the shapes of all and their magnitudes and distances from the earth, and the thicknesses and number, and greatness and smallness, … It likewise treats of the size and shape of the habitable earth … All this information is secured by means of instruments suitable for these purposes, and by tables and by canons.. For everything works through innate forces shown by lines, angles and figures.

“The use of method as the criterion of science abolishes theoretical relevance. As a consequence, all propositions concerning facts will be promoted to the dignity of science, regardless of their relevance, as long as they result from a correct use of method. Since the ocean of facts is infinite, a prodigious expansion of science in the sociological sense becomes possible, giving employment to scientistic technicians and leading to the fantastic accumulation of irrelevant knowledge through huge “research projects” whose most interesting features is the quantifiable expense that has gone into their production.”
