Sri Ramana Gita

In the 1661 translation by Thomas Salusbury: … such are the pure Mathematical sciences, to wit, Geometry and Arithmetick: in which Divine Wisdom knows infinite more propositions, because it knows them all; but I believe that the knowledge of those few comprehended by humane understanding, equalleth the divine, as to the certainty objectivè, for that it arriveth to comprehend the neces­sity thereof, than which there can be no greater certainty." p. 92 (from the Archimedes Project http://archimedes.mpiwg-berlin.mpg.de/cgi-bin/toc/toc.cgi?page=92;dir=galil_syste_065_en_1661;step=textonly)
In the original Italian: … tali sono le scienze matematiche pure, cioè la geometria e l’aritmetica, delle quali l’intelletto divino ne sa bene infinite proposizioni di piú, perché le sa tutte, ma di quelle poche intese dall’intelletto umano credo che la cognizione agguagli la divina nella certezza obiettiva, poiché arriva a comprenderne la necessità, sopra la quale non par che possa esser sicurezza maggiore."

Oration on the Dignity of Man (1496)

Bunmeiron no Gairyaku [An Outline of a Theory of civilization] (1875).
Context: In its broad sense, civilization means not only comfort in daily necessities but also the refining of knowledge and the cultivation of virtue so as to elevate human life to a higher plane... It refers to the attainment of both material well-being and the elevation of the human spirit, [but] since what produces man’s well-being and refinement is knowledge and virtue, civilization ultimately means the progress of man’s knowledge and virtue.

28
Golden Sayings of Epictetus

1940s, Philosophy for Laymen (1946)
Context: The pursuit of philosophy is founded on the belief that knowledge is good, even if what is known is painful. A man imbued with the philosophic spirit, whether a professional philosopher or not, will wish his beliefs to be as true as he can make them, and will, in equal measure, love to know and hate to be in error. This principle has a wider scope than may be apparent at first sight.

Source: The Natural History of the Soul (1745), Ch. VI Concerning the Sensitive Faculty of Matter

Martí : Thoughts/Pensamientos (1994)
Context: Happiness exists on earth, and it is won through prudent exercise of reason, knowledge of the harmony of the universe, and constant practice of generosity. He who seeks it elsewhere will not find it for, having drunk from all the glasses of life, he will find satisfaction only in those.

In Search of the Miraculous (1949)
Context: Objective knowledge, the idea of unity included, belongs to objective consciousness. The forms which express this knowledge when perceived by subjective consciousness are inevitably distorted and, instead of truth, they create more and more delusions. With objective consciousness it is possible to see and feel the unity of everything. But for subjective consciousness the world is split up into millions of separate and unconnected phenomena. Attempts to connect these phenomena into some sort of system in a scientific or philosophical way lead to nothing because man cannot reconstruct the idea of the whole starting from separate facts and they cannot divine the principles of the division of the whole without knowing the laws upon which this division is based.

Meditation Symbols in Eastern & Western Mysticism (1988)
Context: The alchemical tradition assumes that every physical art or science is a body of knowledge which exists only because it is ensouled by invisible powers and processes. Physical chemistry, as it is practiced in the modern world, is concerned principally with pharmaceutical or industrial research projects. It is confined within the boundaries of an all-pervading materialism, which binds labor to the advancement of physical objectives.

1940s, Philosophy for Laymen (1946)
Context: The demand for certainty is one which is natural to man, but is nevertheless an intellectual vice. If you take your children for a picnic on a doubtful day, they will demand a dogmatic answer as to whether it will be fine or wet, and be disappointed in you when you cannot be sure. The same sort of assurance is demanded, in later life, of those who undertake to lead populations into the Promised Land. “Liquidate the capitalists and the survivors will enjoy eternal bliss.” “Exterminate the Jews and everyone will be virtuous.” “Kill the Croats and let the Serbs reign.” “Kill the Serbs and let the Croats reign.” These are samples of the slogans that have won wide popular acceptance in our time. Even a modicum of philosophy would make it impossible to accept such bloodthirsty nonsense. But so long as men are not trained to withhold judgment in the absence of evidence, they will be led astray by cocksure prophets, and it is likely that their leaders will be either ignorant fanatics or dishonest charlatans. To endure uncertainty is difficult, but so are most of the other virtues. For the learning of every virtue there is an appropriate discipline, and for the learning of suspended judgment the best discipline is philosophy.
But if philosophy is to serve a positive purpose, it must not teach mere skepticism, for, while the dogmatist is harmful, the skeptic is useless. Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or of ignorance.

Letter from Naples, Italy to Otto Grautoff (1896); as quoted in A Gorgon's Mask: The Mother in Thomas Mann's Fiction (2005) by Lewis A. Lawson, p. 34
Context: I think of my suffering, of the problem of my suffering. What am I suffering from? From knowledge — is it going to destroy me? What am I suffering from? From sexuality — is it going to destroy me? How I hate it, this knowledge which forces even art to join it! How I hate it, this sensuality, which claims everything fine and good is its consequence and effect. Alas, it is the poison that lurks in everything fine and good! — How am I to free myself of knowledge? By religion? How am I to free myself of sexuality? By eating rice?

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: Resignation as to knowledge of the world is for me not an irretrievable plunge into a scepticism which leaves us to drift about in life like a derelict vessel. I see in it that effort of honesty which we must venture to make in order to arrive at the serviceable world-view which hovers within sight. Every world-view which fails to start from resignation in regard to knowledge is artificial and a mere fabrication, for it rests upon an inadmissible interpretation of the universe.

Fiction, Hypnos (1922)

The Notebooks of Leonardo da Vinci (1883), II Linear Perspective
Context: Drawing is based upon perspective, which is nothing else than a thorough knowledge of the function of the eye. And this function simply consists in receiving in a pyramid the forms and colours of all the objects placed before it. I say in a pyramid, because there is no object so small that it will not be larger than the spot where these pyramids are received into the eye. Therefore, if you extend the lines from the edges of each body as they converge you will bring them to a single point, and necessarily the said lines must form a pyramid.

1979
Context: On theory: "I don’t know any theory. Knowing the theory does not mean anything. If we theoretically know what a human being is, but someone has never seen one, or if you have never had a relationship with a human being, you cannot know anything about human beings! I think that the best way to gain knowledge is through gaining experience and through connections... Look, if I approach an instrument theoretically, it will give me a theory, so therefore this will make cold music".

"A Man of the People", p. 140
Four Ways to Forgiveness (1995)
Context: “Lines and colors made with earth on earth may hold knowledge in them. All knowledge is local, all truth is partial,” Havzhiva said with an easy, colloquial dignity that he knew was an imitation of his mother, the Heir of the Sun, talking to foreign merchants. “No truth can make another truth untrue. All knowledge is a part of the whole knowledge. A true line, a true color. Once you have seen the larger patttern, you cannot go back to seeing the part as the whole."

Book 9, Ch. 16
Variant translations:
Of all men's miseries the bitterest is this: to know so much and to have control over nothing.
The most hateful torment for men is to have knowledge of everything but power over nothing.
The Histories

The Art of Persuasion
Context: One of the principal reasons that diverts those who are entering upon this knowledge so much from the true path which they should follow, is the fancy that they take at the outset that good things are inaccessible, giving them the name great, lofty, elevated, sublime. This destroys everything. I would call them low, common, familiar: these names suit it better; I hate such inflated expressions.

Nītiśataka 8; translation of K.M. Joglekar
Śatakatraya

1790s, Discourse to the Theophilanthropists (1798)
Context: The evil that has resulted from the error of the schools in teaching natural philosophy as an accomplishment only has been that of generating in the pupils a species of atheism. Instead of looking through the works of creation to the Creator Himself, they stop short and employ the knowledge they acquire to create doubts of His existence. They labor with studied ingenuity to ascribe everything they behold to innate properties of matter and jump over all the rest by saying that matter is eternal.

2013, Commencement Address at Ohio State University (May 2013)
Context: You were born as freedom forced its way through a wall in Berlin, and tore down an Iron Curtain across Europe. You were educated in an era of instant information that put the world’s accumulated knowledge at your fingertips. And you came of age as terror touched our shores; an historic recession spread across the nation; and a new generation signed up to go to war. 
You have been tested and tempered by events that your parents and I never imagined we’d see when we sat where you sit. And yet, despite all this, or more likely because of it, yours has become a generation possessed with that most American of ideas – that people who love their country can change it. For all the turmoil; for all the times you have been let down, or frustrated at the hand you’ve been dealt; what I have seen from your generation are perennial and quintessentially American values. Altruism. Empathy. Tolerance. Community. And a deep sense of service that makes me optimistic for our future.

Idée Générale de la Révolution au XIXe Siècle [The General Idea of the Revolution] (1851); quoted in The Anarchists (1964) by James Joll, Ch. 3, p. 78
Context: To be governed is to be watched over, inspected, spied on, directed, legislated at, regulated, docketed, indoctrinated, preached at, controlled, assessed, weighed, censored, ordered about, by men who have neither the right, nor the knowledge, nor the virtue. … To be governed is to be at every operation, at every transaction, noted, registered, enrolled, taxed, stamped, measured, numbered, assessed, licensed, authorized, admonished, forbidden, reformed, corrected, punished. It is, under the pretext of public utility, and in the name of the general interest, to be placed under contribution, trained, ransomed, exploited, monopolized, extorted, squeezed, mystified, robbed; then, at the slightest resistance, the first word of complaint, to be repressed, fined, despised, harassed, tracked, abused, clubbed, disarmed, choked, imprisoned, judged, condemned, shot, deported, sacrificed, sold, betrayed; and, to crown all, mocked, ridiculed, outraged, dishonoured. That is government; that is its justice; that is its morality.

De Re Militari (also Epitoma Rei Militaris), Book I, "The Selection and Training of New Levies"
Context: The courage of a soldier is heightened by his knowledge of his profession, and he only wants an opportunity to execute what he is convinced he has been perfectly taught. (Book 1)

Book I, Ch. IX, pp. 73-76.
Physics

Sec. 94
Source: Some Thoughts Concerning Education (1693)
Context: 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.

All and Everything: Views from the Real World (1973)
Context: Knowledge can be acquired by a suitable and complete study, no matter what the starting point is. Only one must know how to "learn." What is nearest to us is man; and you are the nearest of all men to yourself. Begin with the study of yourself; remember the saying "Know thyself."

"What We Must Do"
1920s, Why I Am Not a Christian (1927)
Context: The whole conception of God is a conception derived from the ancient Oriental despotisms. It is a conception quite unworthy of free men. When you hear people in church debasing themselves and saying that they are miserable sinners, and all the rest of it, it seems contemptible and not worthy of self-respecting human beings. We ought to stand up and look the world frankly in the face. We ought to make the best we can of the world, and if it is not so good as we wish, after all it will still be better than what these others have made of it in all these ages. A good world needs knowledge, kindliness, and courage; it does not need a regretful hankering after the past, or a fettering of the free intelligence by the words uttered long ago by ignorant men.

Source: The Spiritual Life (1947), p. 267
Context: The ethic of reverence for life constrains all, in whatever walk of life they may find themselves, to busy themselves intimately with all the human and vital processes which are being played out around them, and to give themselves as men to the man who needs human help and sympathy. It does not allow the scholar to live for his science alone, even if he is very useful to the community in so doing. It does not permit the artist to exist only for his art, even if he gives inspiration to many by its means. It refuses to let the business man imagine that he fulfills all legitimate demands in the course of his business activities. It demands from all that they should sacrifice a portion of their own lives for others. In what way and in what measure this is his duty, this everyone must decide on the basis of the thoughts which arise in himself, and the circumstances which attend the course of his own life. The self-sacrifice of one may not be particularly in evidence. He carries it out simply by continuing his normal life. Another is called to some striking self-surrender which obliges him to set on one side all regard for his own progress. Let no one measure himself by his conclusions respecting someone else. The destiny of men has to fulfill itself in a thousand ways, so that goodness may be actualized. What every individual has to contribute remains his own secret. But we must all mutually share in the knowledge that our existence only attains its true value when we have experienced in ourselves the truth of the declaration: 'He who loses his life shall find it.

2018, Nelson Mandela Annual Lecture (2018)
Context: A politics of fear and resentment and retrenchment began to appear, and that kind of politics is now on the move. It’s on the move at a pace that would have seemed unimaginable just a few years ago. I am not being alarmist, I am simply stating the facts. Look around. Strongman politics are ascendant suddenly, whereby elections and some pretense of democracy are maintained – the form of it – but those in power seek to undermine every institution or norm that gives democracy meaning. In the West, you’ve got far-right parties that oftentimes are based not just on platforms of protectionism and closed borders, but also on barely hidden racial nationalism. Many developing countries now are looking at China’s model of authoritarian control combined with mercantilist capitalism as preferable to the messiness of democracy. Who needs free speech as long as the economy is going good? The free press is under attack. Censorship and state control of media is on the rise. Social media – once seen as a mechanism to promote knowledge and understanding and solidarity – has proved to be just as effective promoting hatred and paranoia and propaganda and conspiracy theories.

XI, 26, Parts of this passage has been heavily compared with later statements of René Descartes; in Latin and with a variant translations:
The City of God (early 400s)
Context: We both are, and know that we are, and delight in our being, and our knowledge of it. Moreover, in these three things no true-seeming illusion disturbs us; for we do not come into contact with these by some bodily sense, as we perceive the things outside of us of all which sensible objects it is the images resembling them, but not themselves which we perceive in the mind and hold in the memory, and which excite us to desire the objects. But, 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. And, consequently, neither am I deceived in knowing that I know. For, as I know that I am, so I know this also, that I know. And when I love these two things, I add to them a certain third thing, namely, my love, which is of equal moment. For neither am I deceived in this, that I love, since in those things which I love I am not deceived; though even if these were false, it would still be true that I loved false things. For how could I justly be blamed and prohibited from loving false things, if it were false that I loved them? But, since they are true and real, who doubts that when they are loved, the love of them is itself true and real? Further, as there is no one who does not wish to be happy, so there is no one who does not wish [themself] to be [into being]. For how can he be happy, if he is nothing?

Source: Mind is a Myth (1987), Ch. 1: The Certainty That Blasts Everything
Context: Our mind (and there are no individual minds — only "mind", which is the accumulation of man's knowledge and experience) has created the notion of the psyche and evolution. Only technology progresses, while we as a race are moving closer to complete and total destruction of the world and ourselves. Everything in man's consciousness is pushing the whole world, which nature has so laboriously created, toward destruction. There has been no qualitative change in man's thinking; we feel about our neighbours just as the frightened caveman felt towards his. The only thing that has changed is our ability to destroy our neighbor and his property.

The Temple of the Golden Pavilion (1959).
Context: What transforms this world is — knowledge. Do you see what I mean? Nothing else can change anything in this world. Knowledge alone is capable of transforming the world, while at the same time leaving it exactly as it is. When you look at the world with knowledge, you realize that things are unchangeable and at the same time are constantly being transformed. You may ask what good it does us. Let's put it this way — human beings possess the weapon of knowledge in order to make life bearable. For animals such things aren't necessary. Animals don't need knowledge or anything of the sort to make life bearable. But human beings do need something, and with knowledge they can make the very intolerableness of life a weapon, though at the same time that intolerableness is not reduced in the slightest. That's all there is to it.

Politics
Context: There can be no doubt that children should be taught those useful things which are really necessary, but not all things, for occupations are divided into liberal and illiberal; and to young children should be imparted only such kinds of knowledge as will be useful to them without vulgarizing them. And any occupation, art, or science which makes the body, or soul, or mind of the freeman less fit for the practice or exercise of virtue is vulgar; wherefore we call those arts vulgar which tend to deform the body, and likewise all paid employments, for they absorb and degrade the mind. There are also some liberal arts quite proper for a freeman to acquire, but only in a certain degree, and if he attend to them too closely, in order to attain perfection in them, the same evil effects will follow.

"On Elementary Instruction in Physiology" (1877) http://aleph0.clarku.edu/huxley/CE3/ElPhys.html
1870s
Context: 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?

Letter to Christian Northoff (1497), as translated in Collected Works of Erasmus (1974), p. 114

Vol. I, Part 1, [The Materialist Conception of History].
The German Ideology (1845/46)
Context: Where speculation ends — in real life — there real, positive science begins: the representation of the practical activity, of the practical process of development of men. Empty talk about consciousness ceases, and real knowledge has to take place. When reality is depicted, philosophy as an independent branch of activity loses its medium of existence. At the best its place can only be taken by a summing-up of the most general results, abstractions which arise from the observation of the historical development of men. Viewed apart from real history, these abstractions have in themselves no value whatsoever. They can only serve to facilitate the arrangement of historical material, to indicate the sequence of its separate strata. But they by no means afford a recipe or schema, as does philosophy, for neatly trimming the epochs of history. On the contrary, our difficulties begin only when we set about the observation and the arrangement — the real depiction — of our historical material, whether of a past epoch or of the present.

Source: The Spiritual Life (1947), p. 102
Context: When Christianity becomes conscious of its innermost nature, it realizes that it is godliness rising our of inward constraint. The highest knowledge is to know that we are surrounded by mystery. Neither knowledge nor hope for the future can be the pivot of our life or determine its direction. It is intended to be solely determined by our allowing ourselves to be gripped by the ethical God, who reveals Himself in us, and by our yielding our will to His.

Lines (1795)
Context: If Thou be one whose heart the holy forms
Of young imagination have kept pure
Stranger! henceforth be warned; and know that pride,
Howe'er disguised in its own majesty,
Is littleness; that he who feels contempt
For any living thing, hath faculties
Which he has never used; that thought with him
Is in its infancy. The man whose eye
Is ever on himself doth look on one,
The least of Nature's works, one who might move
The wise man to that scorn which wisdom holds
Unlawful, ever. O be wiser, thou!
Instructed that true knowledge leads to love;
True dignity abides with him alone
Who, in the silent hour of inward thought,
Can still suspect, and still revere himself,
In lowliness of heart.

Sec. 95
Some Thoughts Concerning Education (1693)
Context: A father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in. For it is easy to observe, that many young men continue longer in thought and conversation of school-boys than otherwise they would, because their parents keep them at that distance, and in that low rank, by all their carriage to them.

No. 15
On the Interpretation of Nature (1753)
Context: There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.

Maxim no .1.
The Maxims of Ptahhotep (c. 2350 BCE)
Context: Do not be arrogant because of your knowledge, but confer with the ignorant man as with the learned. For knowledge has no limits, and none has yet achieved perfection in it. Good speech is more hidden than malachite, yet it is found in the possession of women slaves at the millstones.

The Dawn http://poetry.poetryx.com/poems/1612/
The Wild Swans at Coole (1919)
Context: I would be ignorant as the dawn
That merely stood, rocking the glittering coach
Above the cloudy shoulders of the horses;
I would be — for no knowledge is worth a straw —
Ignorant and wanton as the dawn.

Go Rin No Sho (1645), The Book No-Thing-ness
Context: What is called the spirit of the void is where there is nothing. It is not included in man's knowledge. Of course the void is nothingness. By knowing things that exist, you can know that which does not exist. That is the void.

Speech at Founding Rally of the Organization of Afro-American Unity (28 June 1964), as quoted in By Any Means Necessary (1970)

Context: Armed with the knowledge of our past, we can with confidence charter a course for our future. Culture is an indispensable weapon in the freedom struggle. We must take hold of it and forge the future with the past.
