Quotes about certainty
page 4

“Man's quest for knowledge is an expanding series whose limit is infinity, but philosophy seeks to attain that limit at one blow, by a short circuit providing the certainty of complete and inalterable truth. Science meanwhile advances at its gradual pace, often slowing to a crawl, and for periods it even walks in place, but eventually it reaches the various ultimate trenches dug by philosophical thought, and, quite heedless of the fact that it is not supposed to be able to cross those final barriers to the intellect, goes right on.”

“The very desire for guarantees that our values are eternal and secure in some objective heaven is perhaps only a craving for the certainties of childhood or the absolute values of our primitive past.”

“It makes no sense to expect or claim to 'make the invisible visible', or the unknown known, or the unthinkable thinkable. We can draw conclusions about the invisible; we can postulate its existence with relative certainty. But all we can represent is an analogy, which stands for the invisible but is not it.”

“As a race of scientists and thinkers,” she concluded, “we cannot claim with absolute certainty that Teot Yon’s personality is now beyond Heaven’s gates or inside Satan’s stewpot or about to enter the embryo of a bull. Some of us subscribe to the Afterworld Hypothesis, some to less cheerful views. We all know that as an empirical event Teot Yon’s existence is over, and it is time for his molecules to become air and ash and after that—where will his drifting pieces go and what new things will they help to form? Let the transformation begin!”

“Some years ago, an American psychologist, Abraham Maslow, felt the same kind of instinctive revolt against the 'atmosphere' of Freudian psychology, with its emphasis on sickness and neurosis, and decided that he might obtain some equally interesting results if he studied extremely healthy people. He therefore looked around for the most cheerful and well-adjusted people he could find, and asked for their co-operation in his studies. He soon discovered and interesting fact: that most extremely healthy people frequently experience of intense affirmation and certainty; Maslow called these 'peak experiences.' No one had made this discovery before because it had never struck anyone that a science calling itself 'psychology' and professing to be a science of the human mind (not merely the sick mind), ought to form its estimate of human beings by taking into account healthy minds as well as sick ones. A sick man talks obsessively about his illness; a healthy man never talks about his health; for as Pirandello points out, we take happiness for granted, and only begin to question life when we are unhappy. Hence no psychologist ever made this simple and obvious discovery about peak experiences.”

“Mathematics, from the earliest times to which the history of human reason can reach, has followed, among that wonderful people of the Greeks, the safe way of science. But it must not be supposed that it was as easy for mathematics as for logic, in which reason is concerned with itself alone, to find, or rather to make for itself that royal road. I believe, on the contrary, that there was a long period of tentative work (chiefly still among the Egyptians), and that the change is to be ascribed to a revolution, produced by the happy thought of a single man, whose experiments pointed unmistakably to the path that had to be followed, and opened and traced out for the most distant times the safe way of a science. The history of that intellectual revolution, which was far more important than the passage round the celebrated Cape of Good Hope, and the name of its fortunate author, have not been preserved to us. … A new light flashed on the first man who demonstrated the properties of the isosceles triangle (whether his name was Thales or any other name), for he found that he had not to investigate what he saw hi the figure, or the mere concepts of that figure, and thus to learn its properties; but that he had to produce (by construction) what he had himself, according to concepts a priori, placed into that figure and represented in it, so that, in order to know anything with certainty a priori, he must not attribute to that figure anything beyond what necessarily follows from what he has himself placed into it, in accordance with the concept.”

“Our civilization has essentially globalized only the surfaces of our lives. But our inner self continues to have a life of its own. And the fewer answers the era of rational knowledge provides to the basic questions of human Being, the more deeply it would seem that people, behind its back as it were, cling to the ancient certainties of their tribe. Because of this, individual cultures, increasingly lumped together by contemporary civilization, are realizing with new urgency their own inner autonomy and the inner differences of others.”

“The last century was defined by physics. From the minds of the world’s leading physicists there flowed a river of ideas that would transport man kind to the very pinnacle of wonder and to the very depths of despair. This was a century that began with the certainties of absolute knowledge and ended with the knowledge of absolute uncertainty. It was a century in which physicists developed theories that would deny us the possibility that we can ever properly comprehend the nature of physical reality. It was also a century in which they built weapons with the capacity utterly to destroy this reality.”

“Why in this world of ours there should be so much suffering no one knows. But this we know; that, evil existing, the world being such as it is, we can win from evil, if we choose, an inestimable good, namely — the conviction that there is in us a power not of the senses, the conviction that spirit exists, and exists in us.
A sceptic may say that in a world ideally conceivable we might have secured this precious conviction without the necessity of undergoing the ordeal of pain. To which the reply is: that in a world ideally conceivable what he says may be true; but in the world as it is, with which alone we are concerned, we have ample cause for gratitude that we can turn suffering to such far-reaching account, that we can distil from the bitter root this divine elixir; that by manfully bearing the pains of the senses, inexplicable though they be, we are able to gain the certainty that a power not born of the senses exists in us, operates in us. It is this effect of pain that accounts for the serenity and peace of many patient sufferers, a peace and a serenity which surround their bed of misery with a kind of halo.”

“This statement appears to us to be conclusive with respect to the insufficiency of the undulatory theory, in its present state, for explaining all the phenomena of light. But we are not therefore by any means persuaded of the perfect sufficiency of the projectile system: and all the satisfaction that we have derived from an attentive consideration of the accumulated evidence, which has been brought forward, within the last ten years, on both sides of the question, is that of being convinced that much more evidence is still wanting before it can be positively decided. In the progress of scientific investigation, we must frequently travel by rugged paths, and through valleys as well as over mountains. Doubt must necessarily succeed often to apparent certainty, and must again give place to a certainty of a higher order; such is the imperfection of our faculties, that the descent from conviction to hesitation is not uncommonly as salutary, as the more agreeable elevation from uncertainty to demonstration. An example of such alternations may easily be adduced from the history of chemistry. How universally had phlogiston once expelled the aërial acid of Hooke and Mayow. How much more completely had phlogiston given way to oxygen! And how much have some of our best chemists been lately inclined to restore the same phlogiston to its lost honours! although now again they are beginning to apprehend that they have already done too much in its favour. In the mean time, the true science of chemistry, as the most positive dogmatist will not hesitate to allow, has been very rapidly advancing towards ultimate perfection.”

Question

“I don't think it's healthy for people to want there to be a permanent, unalterable, irremovable authority over them. I don't like the idea of a father who never goes away, the idea of a king who cannot be deposed, the idea of a judge who doesn't allow a lawyer or a jury or an appeal. This is an appeal to absolutism. It's the part of ourselves that's not so nice; that wants security, that wants certainty, that wants to be taken care of. For hundreds and hundreds of years, the human struggle for freedom was against the worst kind of dictatorship of all: the theocracy, the one that claims it has God on its side. I believe that totalitarian temptation has to be resisted. What I'm inviting you to do is to consider emancipating yourselves from the idea that you, selfishly, are the sole object of all the wonders of the cosmos and of nature - because that's not a humble idea at all, it's a very arrogant one and there's no evidence for it. And then, again, the second emancipation - to think of yourselves as free citizens who are not enthralled to any supernatural-eternal authority; which you will always find is interpreted for you by other mammals who claim to have access to this authority - that gives them special power over you. Don't allow yourselves to have your lives run like that.”

“I shall now no more behold my dear father with these "bodily eyes. With him a whole threescore and ten years of the past has doubly died for me. It is as if a new leaf in the great hook of time were turned over. Strange time — endless time or of which I see neither end nor beginning. All rushes on. Man follows man. His life is as a tale that has been told; yet under Time does there not lie Eternity? Perhaps my father, all that essentially was my father, is even now near me, with me. Both he and I are with God. Perhaps, if it so please God, we shall in some higher state of being meet one another, recognize one another. As it is written. We shall be forever with God. The possibility, nay (in some way), the certainty, of perennial existence daily grows plainer to me. "The essence of whatever was, is, or shall be, even now is." God is great. God is good. His will be done, for it will be right. As it is, I can think peaceably of the departed love. All that was earthly, harsh, sinful, in our relation has fallen away; all that was holy in it remains. I can see my dear father's life in some measure as the sunk pillar on which mine was to rise and be built; the waters of time have now swelled up round his (as they will round mine); I can see it all transfigured, though I touch it no longer. I might almost say his spirit seems to have entered into me (so clearly do I discern and love him); I seem to myself only the continuation and second volume of my father. These days that I have spent thinking of him and of his end are the peaceablest, the only Sabbath that I have had in London. One other of the universal destinies of man has overtaken me. Thank Heaven, I know, and have known, what it is to be a son; to love a father, as spirit can love spirit. God give me to live to my father's honor and to His. And now, beloved father, farewell for the last time in this world of shadows I In the world of realities may the Great Father again bring us together in perfect holiness and perfect love! Amen!”

“I’m not against a global pact to reduce CO2. Indeed, I favor it. But in the absence of one — and there is no chance of getting one in the foreseeable future — there is no point in America committing economic suicide to no effect on climate change, the reversing of which, after all, is the alleged point of the exercise. For a president to propose this with such aggressive certainty is incomprehensible. It is the starkest of examples of belief that is impervious to evidence. And the word for that is faith, not science.”

“I think you're right about the difference between the Trojan mind and the Greek mind: the Greeks live in their imaginations while the Trojans always try to see things as they really are. And with some things they do get hold of the truth, and with some things they don't. But, where they don't, they won't have substitutes. That's why their world-outlook is so much smaller than ours. It's concentrated in a few certainties which are far ahead of anything we'll arrive at, but when you have these you feel that the rest is a blank and long to be back in the bigger world again, where there's space and variety and perplexity.”

“The anti‐Semite has chosen hate because hate is a faith; at the outset he has chosen to devaluate words and reasons. How entirely at ease he feels as a result. How futile and frivolous discussions about the rights of the Jew appear to him. He has placed himself on other ground from the beginning. If out of courtesy he consents for a moment to defend his point of view, he lends himself but does not give himself. He tries simply to project his intuitive certainty onto the plane of discourse. I mentioned awhile back some remarks by anti‐Semites, all of them absurd: "I hate Jews because they make servants insubordinate, because a Jewish furrier robbed me, etc." Never believe that anti‐ Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti‐Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past. It is not that they are afraid of being convinced. They fear only to appear ridiculous or to prejudice by their embarrassment their hope of winning over some third person to their side.”

“I want to ask this congregation, every man, woman and child, to answer the question in their own heart, what kind of a being God is?... Does any man or woman know? Have any of you seen him, heard him, or communed with him?... God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! That is the great secret. If the veil were rent today, and the great God who holds this world in its orbit, and who upholds all worlds and all things by his power, was to make Himself visible,—I say, if you were to see Him today, you would see Him like a man in form—like yourselves in all the person, image, and very form as a man; for Adam was created in the very fashion, image and likeness of God, and received instruction from, and walked, talked and conversed with Him, as one man talks and communes with another.... It is the first principle of the Gospel to know for a certainty the Character of God, and to know that we may converse with him as one man converses with another, and that He was once a man like us; yea, that God Himself, the Father of us all, dwelt on an earth, the same as Jesus Christ himself did; and I will show it from the Bible.”

“A finished or even a competent reasoner is not the work of nature alone… education develops faculties which would otherwise never have manifested their existence. It is, therefore, as necessary to learn to reason before we can expect to be able to reason, as it is to learn to swim or fence, in order to attain either of those arts. Now, something must be reasoned upon, it matters not much what it is, provided that it can be reasoned upon with certainty. The properties of mind or matter, or the study of languages, mathematics, or natural history may be chosen for this purpose. Now, of all these, it is desirable to choose the one… in which we can find out by other means, such as measurement and ocular demonstration of all sorts, whether the results are true or not.
.. Now the mathematics are peculiarly well adapted for this purpose, on the following grounds:—
1. Every term is distinctly explained, and has but one meaning, and it is rarely that two words are employed to mean the same thing.
2. The first principles are self-evident, and, though derived from observation, do not require more of it than has been made by children in general.
3. The demonstration is strictly logical, taking nothing for granted except the self-evident first principles, resting nothing upon probability, and entirely independent of authority and opinion.
4. When the conclusion is attained by reasoning, its truth or falsehood can be ascertained, in geometry by actual measurement, in algebra by common arithmetical calculation. This gives confidence, and is absolutely necessary, if… reason is not to be the instructor, but the pupil.
5. There are no words whose meanings are so much alike that the ideas which they stand for may be confounded.
…These are the principal grounds on which… the utility of mathematical studies may be shewn to rest, as a discipline for the reasoning powers. But the habits of mind which these studies have a tendency to form are valuable in the highest degree. The most important of all is the power of concentrating the ideas which a successful study of them increases where it did exist, and creates where it did not. A difficult position or a new method of passing from one proposition to another, arrests all the attention, and forces the united faculties to use their utmost exertions. The habit of mind thus formed soon extends itself to other pursuits, and is beneficially felt in all the business of life.”

“In spite of the many valuable books available today, the state of Prokofiev scholarship cannot be considered adequate: suffice it to say that the detailed catalogue of his works has not been updated since it was published in 1961. At present, there is no edition of the Prokofiev sonatas free of errors. I have tried to do my best in pointing out some obvious mistakes, as well as certain doubtful readings. Many questions cannot be answered with certainty, as the manuscripts for some of the sonatas have been lost; those that have survived are not easily available for inspection.

“There is now a strong movement in this country to bring the public school system under federal domination. The movement could not have been thought of before the government had the means for carrying out the idea; that is, before income taxation. The question is, have those who plug for nationalization of the schools come to the idea by independent thought, or have they been influenced by the bureaucrats who see in nationalization a wider opportunity for themselves? We must lean to the latter conclusion, because among the leaders of the movement are many bureaucrats. However, if the movement is successful, if the schools are brought under the watching eye of the federal government, it is a certainty that the curriculum will conform to the ideals of Big Government. The child’s mind will never be exposed to the idea that the individual is the one big thing in the world, that he has rights which come from a higher source than the bureaucracy.”

“Politics have always covered two distinct kinds of problems: problems of administrative routine, and those that may be called 'questions of the moment.'… A question of the moment is, indeed, a substitute for some notion, such as the idea of God, or hereditary monarchy, or national glory, that has hitherto acted as a symbol of human co-ordination.

““Our ideas” are only partly our ideas. Most of our ideas are abbreviations or residues of the thought of other people, of our teachers (in the broadest sense of the term) and of our teachers’ teachers; they are abbreviations and residues of the thought of the past. These thoughts were once explicit and in the center of consideration and discussion. It may even be presumed that they were once perfectly lucid. By being transmitted to later generations they have possibly been transformed, and there is no certainty that the transformation was effected consciously and with full clarity. … This means that the clarification of our political ideas insensibly changes into and becomes indistinguishable from the history of political ideas.”

“Certainty is the mark of the common-sense life: gracious uncertainty is the mark of the spiritual life. To be certain of God means that we are uncertain in all our ways, we do not know what a day may bring forth. This is generally said with a sigh of sadness, it should be rather an expression of breathless expectation. We are uncertain of the next step, but we are certain of God. Immediately we abandon to God, and do the duty that lies nearest, He packs our life with surprises all the time.”

“Love and desire are both thoroughly human. Our problem with them is that they orient us toward very different goals. Love seeks control, stability, continuity, certainty. Desire seeks surrender, adventure, novelty, the unknown. In love we are searching for points of attachment, anchoring, something we know we can count on. In desire we are searching both for missing, disowned pieces of ourselves and for something beyond ourselves, outside the borders of self-recognition that, under ordinary circumstances, we protect so fiercely.Erotic passion destabilizes one's sense of self. When we find someone intensely arousing who makes possible unfamiliar experiences of ourselves and an otherness we find captivating, we are drawn into the disorienting loopiness of self/other. We tend to want to control these experiences and the others who inspire them. Thus emotional connection tends to degrade into strategies for false security that suffocate desire.”

They joined in the dinner-table discussions and from childhood the boys were accustomed to hear, almost every day, table-talk as good as they were ever likely to hear again. The eldest child, Louisa, was one of the most sparkling creatures her brother met in a long and varied experience of bright women.”

If the addressee receives the telegram a few hours or days later and reads it, he merely knows that the sender was alive at the very instant the telegram was sent. But when he is reading the telegram, he is totally uncertain if the content of the text is still relevant or if it is still valid The difference, the small displacement between sending and receiving, is that particular unseizable glimpse of the presence of the artist.

A certainty with respect to provision and forage is an object of the first consideration in taking a position.

“The picture of law triumphant and justice prostrate, is not, I am aware, without admirers. To me it is a sorry spectacle. The spirit of justice does not reside in formalities, or words, nor is the triumph of its administration to be found in successfully picking a way between the pitfalls of technicality. After all, the law is, or ought to be, but the handmaid of justice, and inflexibility, which is the most becoming robe of the latter, often serves to render the former grotesque. But any real inroad upon the rights and opportunities for defence of a person charged with a breach of the law, whereby the certainty of justice might be imperilled, I conceive to be a matter of the highest moment.”

“There were many reasons why we did not gain complete success at Arnhem. The following in my view were the main ones. First. The operation was not regarded at Supreme Headquarters as the spearhead of a major Allied movement on the northern flank designed to isolate, and finally to occupy, the Ruhr - the one objective in the West which the Germans could not afford to lose. There is no doubt in my mind that Eisenhower always wanted to give priority to the northern thrust and to scale down the southern one. He ordered this to be done, and he thought that it was being done. It was not being done. Second. The airborne forces at Arnhem were dropped too far away from the vital objective - the bridge. It was some hours before they reached it. I take the blame for this mistake. I should have ordered Second Army and 1st Airborne Corps to arrange that at least one complete Parachute Brigade was dropped quite close to the bridge, so that it could have been captured in a matter of minutes and its defence soundly organised with time to spare. I did not do so. Third. The weather. This turned against us after the first day and we could not carry out much of the later airborne programme. But weather is always an uncertain factor, in war and in peace. This uncertainty we all accepted. It could only have been offset, and the operation made a certainty, by allotting additional resources to the project, so that it became an Allied and not merely a British project. Fourth. The 2nd S. S. Panzer Corps was refitting in the Arnhem area, having limped up there after its mauling in Normandy. We knew it was there. But we were wrong in supposing that it could not fight effectively; its battle state was far beyond our expectation. It was quickly brought into action against the 1st Airborne Division.”

For these domains, idealized models of optimizing entrepreneurs, equipped with complete certainty about the world - or, a worst, having full probability distributions for uncertain events - are of little use. Models have to be fashioned with an eye to practical computability, no matter how severe the approximations and simplifications that are thereby imposed on them…
The first is to retain optimization, but to simplify sufficiently so that the optimum (in the simplified world!) is computable. The second is to construct satisficing models that provide good enough decisions with reasonable costs of computation. By giving up optimization, a richer set of properties of the real world can be retained in the models… Neither approach, in general, dominates the other, and both have continued to co-exist in the world of management science.”

“Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome. And human beings evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other, yet to be discovered. […] Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us for a style of argument that they themselves favor). In science, “fact” can only mean “confirmed to such a degree that it would be perverse to withhold provisional assent.””

I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.
