No, I'm talking about something more substantial. It's the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores; the hope of a young naval lieutenant bravely patrolling the Mekong Delta; the hope of a millworker's son who dares to defy the odds; the hope of a skinny kid with a funny name who believes that America has a place for him, too.

“Beyond a doubt truth bears the same relation to falsehood as light to darkness; and this truth is in itself so excellent that, even when it dwells on humble and lowly matters, it is still infinitely above uncertainty and lies, disguised in high and lofty discourses; because in our minds, even if lying should be their fifth element, this does not prevent that the truth of things is the chief nutriment of superior intellects, though not of wandering wits. But you who live in dreams are better pleased by the sophistical reasons and frauds of wits in great and uncertain things, than by those reasons which are certain and natural and not so far above us.”

“According to the pronouncements of our state rulers and their intellectual bodyguards (of whom there are more than ever before), we are better protected and more secure than ever. We are supposedly protected from global warming and cooling, from the extinction of animals and plants, from the abuses of husbands and wives, parents and employers, from poverty, disease, disaster, ignorance, prejudice, racism, sexism, homophobia, and countless other public enemies and dangers. In fact, however, matters are strikingly different. In order to provide us with all this protection, the state managers expropriate more than 40 percent of the incomes of private producers year in and year out. Government debt and liabilities have increased without interruption, thus increasing the need for future expropriations. Owing to the substitution of government paper money for gold, financial insecurity has increased sharply, and we are continually robbed through currency depreciation. Every detail of private life, property, trade, and contract is regulated by ever higher mountains of laws legislation), thereby creating permanent legal uncertainty and moral hazard. In particular, we have been gradually stripped of the right to exclusion implied in the very concept of private property. … In short, the more the state has increased its expenditures on social security and public safety, the more our private property rights have been eroded, the more our property has been expropriated, confiscated, destroyed, or depreciated, and the more we have been deprived of the very foundation of all protection: economic independence, financial strength, and personal wealth.”

“He found that if people wrote about uncertain things - past, present, or future - they could be traumatic things, they could be uncertain things, that their physical health improved. He did a lot of detailed research to find out why this is. He basically figured out that it is an uncertainty reduction mechanism at work, because your brain is always figuring out how well situated you are in the world. How much do you not know compared to how much have you mastered. You can tell that you've mastered things because when you go somewhere and you act, things turn out the way you want them to. That's an indication of mastery. And your brain is keeping track of your whole life, recording information about how many places you have been where things haven't worked out compared to how many places you have been where things have worked out. And if all those places in your past where things haven't worked out, you need to map and master. And that decreases the existential load on you, but that actually decreases your psych-physiological load. It makes you healthier. It makes you less stressed. And so we have put all that together in this Self-Authoring Suite to help people write about their past and to sort it out in a detailed auto-biography.”

“My greatest concern was what to call it. I thought of calling it 'information,' but the word was overly used, so I decided to call it 'uncertainty.' When I discussed it with John von Neumann, he had a better idea. Von Neumann told me, 'You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage.”

“ I asked my guide how it was possible the judicious part of them could suffer such incoherent prating? "We are obliged," said he, "to suffer it, because no one knows, when a brother rises up to hold forth, whether he will be moved by the spirit or by folly. In this uncertainty, we listen patiently to every one. We even allow our women to speak in public; two or three of them are often inspired at the same time, and then a most charming noise is heard in the Lord's house." "You have no priests, then?" said I. "No, no, friend," replied the Quaker; "heaven make us thankful!"

“I have never believed that the securing of material resources ought to form the central interest of human life—but have instead maintained that personality is an independent flowering of the intellect and emotions wholly apart from the struggle for existence. Formerly I accepted the archaic dictum that only a few can be relieved of the engulfing waste of the material struggle in its bitterest form—a dictum which is, of course, true in an agricultural age having scanty resources. Therefore I adopted an aristocratic attitude; regretfully arguing that life, in any degree of fulness, is only for the fortunate few whose ancestors' prowess has given them economic security and leisure. But I did not take the bourgeois position of praising struggle for its own sake. While recognising certain worthy qualities brought out by it, I was too much impressed by its stultifying attributes to regard it as other than a necessary evil. In my opinion, only the leisured aristocrat really had a chance at adequate life—nor did I despise him because he was not forced to struggle. Instead, I was sorry that so few could share his good fortune. Too much human energy was wasted in the mere scramble for food and shelter. The condition was tolerable only because inevitable in yesterday's world of scanty resources. Millions of men must go to waste in order that a few might really live. Still—if those few were not upheld, no high culture would ever be built up. I never had any use for the American pioneer's worship of work and self-reliance for their own sakes. These things are necessary in their place, but not ends in themselves—and any attempt to make them ends in themselves is essentially uncivilised. Thus I have no fundamental meeting-ground with the rugged Yankee individualist. I represent rather the mood of the agrarian feudalism which preceded the pioneering and capitalistic phases. My ideal of life is nothing material or quantitative, but simply the security and leisure necessary for the maximum flowering of the human spirit.... Well—so much for the past. Now we live in an age of easy abundance which makes possible the fulfilment of all moderate human wants through a relatively slight amount of labour. What shall be the result? Shall we still make resources prohibitively hard to get when there is really a plethora of them? Shall we allow antique notions of allocation—"property," etc.—to interfere with the rational distribution of this abundant stock of resources among all those who require them? Shall we value hardship and anxiety and uncertainty so fatuously as to impose these evils artificially on people who do not need to bear them, through the perpetuation of a set of now irrelevant and inapplicable rules of allocation? What reasonable objection is there to an intelligent centralised control of resources whose primary object shall be the elimination of want in every quarter—a thing possible without removing comfortable living from any one now enjoying it? To call the allocation of resources something "uncontrollable" by man—and in an age when virtually all natural forces are harnessed and utilised—is simply infantile. It is simply that those who now have the lion's share don't want any fresh or rational allocation. It is needless to say that no sober thinker envisages a workless equalitarian paradise. Much work remains, and human capacities differ. High-grade service must still receive greater rewards than low-grade service. But amidst the present abundance of goods and minimisation of possible work, there must be a fair and all-inclusive allocation of the chances to perform work and secure rewards. When society can't give a man work, it must keep him comfortable without it; but it must give him work if it can, and must compel him to perform it when it is needed. This does not involve interference with personal life and habits (contrary to what some reactionaries say), nor is the absence of insecurity anything to deplore.... But of course the real need of change comes not from the mere fact of abundant resources, but from the growth of conditions making it impossible for millions to have any chance of getting any resources under the present outworn set of artificial rules. This development is no myth. Machines had displaced 900,000 men in the U. S. before the crash of '29, and no conceivable regime of "prosperity" (where by a few people will have abundant and flexible resources and successfully exchange them among one another) will ever make it possible to avoid the permanent presence of millions of unemployed, so long as old-fashioned laissez-faire capitalism is adhered to.... And so I have readjusted my ideas. … I have gone almost reluctantly—step by step, as pressed by facts too insistent to deny—and am still quite as remote from Belknap's naive Marxism as I am from the equally naive Republican orthodoxy I have left behind. I am as set as ever against any cultural upheaval—and believe that nothing of the kind is necessary in order to achieve a new and feasible economic equilibrium. The best of culture has always been non-economic.”

H.P. Lovecraft (1890–1937) American author

Hitherto it has grown out of the secure, non-struggling life of the aristocrat. In future it may be expected to grow out of the secure and not-so-struggling life of whatever citizens are personally able to develop it. There need be no attempt to drag culture down to the level of crude minds. That, indeed, would be something to fight tooth and nail! With economic opportunities artificially regulated, we may well let other interests follow a natural course. Inherent differences in people and in tastes will create different social-cultural classes as in the past—although the relation of these classes to the holding of material resources will be less fixed than in the capitalistic age now closing. All this, of course, is directly contrary to Belknap's rampant Stalinism—but I'm telling you I'm no bolshevik! I am for the preservation of all values worth preserving—and for the maintenance of complete cultural continuity with the Western-European mainstream. Don't fancy that the dethronement of certain purely economic concepts means an abrupt break in that stream. Rather does it mean a return to art impulses typically aristocratic (that is, disinterested, leisurely, non-ulterior) rather than bourgeois.

“Institutions are the humanly devised constraints that structure political, economic, and social interaction. They consist of both informal constraints (sanctions, taboos, customs, traditions, and codes of conduct), and formal rules (constitutions, laws, property rights). Throughout history, institutions have been devised by human beings to create order and reduce uncertainty in exchange.”

“The American model – democracy – must be regarded as a historical error, economically as well as morally. Democracy promotes shortsightedness, capital waste, irresponsibility, and moral relativism. It leads to permanent compulsory income and wealth redistribution and legal uncertainty. It is counterproductive. It promotes demagoguery and egalitarianism. It is aggressive and potentially totalitarian internally, vis-à-vis its own population, as well as externally. In sum, it leads to a dramatic growth of state power, as manifested by the amount of parasitically – by means of taxation and expropriation – appropriated government income and wealth in relation to the amount of productively – through market exchange – acquired private income and wealth, and by the range and invasiveness of state legislation. Democracy is doomed to collapse, just as Soviet communism was doomed to collapse.”

“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.”

Bertrand Russell (1872–1970) logician, one of the first analytic philosophers and political activist

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.

“I pursue no objectives, no systems, no tendency; I have no program, no style, no direction. I have no time for specialized concerns, working themes, or variations that lead to mastery. I steer clear of definitions. I don't know what I want. I am inconsistent, non-committal, passive; I like the indefinite, the boundless; I like continual uncertainty.”

“The difficulty in defining a field for the so-called institutional economics is the uncertainty of meaning of an institution. Sometimes an institution seems to mean a framework of laws or natural rights within which individuals act like inmates. Sometimes it seems to mean the behavior of the inmates themselves. Sometimes anything additional to or critical of the classical or hedonic economics is deemed to be institutional. Sometimes anything that is "economic behavior" is institutional. Sometimes anything that is "dynamic" instead of "static," or a "process" instead of commodities, or activity instead of feelings, or mass action instead of individual action, or management instead of equilibrium, or control instead of laissez faire, seems to be institutional economics.”

“In retrospect… it is interesting to note that the original problem that started my research is still outstanding -- namely the problem of planning or scheduling dynamically over time, particularly planning dynamically under uncertainty. If such a problem could be successfully solved it could eventually through better planning contribute to the well-being and stability of the world.”

“There may be a rationalist who has never wavered in his conviction of the mortality of the soul, and there may be a vitalist who has never wavered in his faith in immortality; but at the most this would prove that just as there are natural monstrosities, so there are those who are stupid as regards heart and feeling, however great their intelligence, and those who are stupid intellectually, however great their virtue. But, in normal cases, I cannot believe those who assure me that never, not in a fleeting moment, not in the hours of direst loneliness and grief, has this murmur of uncertainty breathed upon their consciousness.”

My studio in Amsterdam, [Beckmann lived and worked in the heart of Amsterdam during World War 2. ] an enormous old tobacco storeroom is again filled in my imagination with figures from the old days and from the new, like an ocean moved by storm and sun and always present in my thoughts. Then shapes become beings and seem comprehensible to me in the great void and uncertainty of the space which I call god.”

“Well, at first I wanted to put blinds on the building [of the outdoor-sculpture Josef Strau did for her recently]. But when I do something I've already done before, I sometimes have a certain feeling of uncertainty. Although I am falling back on something that I know is safe and pretty good. But then it was all too expensive. I had seen glowing green, fresh bamboo at the KaDeWe store. It had attracted my attention and I thought it would be nice to do something with it. Back home, sitting over the photo, drawing some things on it, I remembered this lovely green bamboo again and also that there was this fascist building – or partly fascist building – next to the store, a theater, an ugly building. And then I thought, bamboo is politically correct, that's just the thing. But I also think it's visually beautiful. Simple. The work is called 'Haare wachsen wie sie wollen”

“Third, this allowed us to propose what we called the cosmological interpretation of quantum mechanics. Here we interpret the wavefunction for an object as describing not some funky imaginary ensemble of possibilities for what the object might be doing, but rather the actual spatial collection of identical copies of the object that exist in our infinite space. Moreover, quantum uncertainty that you experience simply reflects your inability to self-locate in the Level I multiverse, i. e., to know which of your infinitely many copies throughout space is the one having your subjective perceptions.”

“There are some things that you know to be true, and others that you know to be false; yet, despite this extensive knowledge that you have, there remain many things whose truth or falsity is not known to you. We say that you are uncertain about them. You are uncertain, to varying degrees, about everything in the future; much of the past is hidden from you; and there is a lot of the present about which you do not have full information. Uncertainty is everywhere and you cannot escape from it.”

“We know, since the theory of relativity at least, that empirical sciences are to some degree free in defining dynamical concepts or even in assuming laws, and that only a system as a whole which includes concepts, coordinating definitions, and laws can be said to be either true or false, to be adequate or inadequate to empirical facts. This "freedom," however, is a somewhat doubtful gift. The manifold of possibilities implies uncertainty, and such uncertainty can become rather painful in a science as young as psychology, where nearly all concepts are open and unsettled. As psychology approaches the state of a logically sound science, definitions cease to be an arbitrary matter. They become far-reaching decisions which presuppose the mastering of the conceptual problems but which have to be guided entirely by the objective facts.”

“What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as afield, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes—coercive, mimetic, and normative—leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change.”

“Without precise predictability, control is impotent and almost meaningless. In other words, the lesser the predictability, the harder the entity or system is to control, and vice versa. If our universe actually operated on linear causality, with no surprises, uncertainty, or abrupt changes, all future events would be absolutely predictable in a sort of waveless orderliness.”

“As a result of uncertainties caused by the French referendum, massive speculative flows have continued to disrupt the functioning of the exchange rate mechanism. As Chairman of Ecofin I have tonight called an urgent meeting of the EC's monetary committee to consider how stability might be restored to the markets over the next few days.
In the meantime the Government has decided that Britain's best interests would be best secured by suspending our membership of the ERM with immediate effect. As a result, the second of the two interest rate rises announced today will not take effect.”

“…classic philosophy maintained that change, and consequently time, are marks of inferior reality, holding that true and ultimate reality is immutable and eternal. Human reasons, all too human, have given birth to the idea that over and beyond the lower realm of things that shift like the sands on the seashore there is the kingdom of the unchanging, of the complete, the perfect. The grounds for the belief are couched in the technical language of philosophy, but the grounds for the cause is the heart's desire for surcease from change, struggle, and uncertainty. The eternal and immutable is the consummation of mortal man's quest for certainty.”

“The basic proposition is that the greater the uncertainty of the task, the greater the amount of information that has to be processed between decision-makers during the execution of the task. If the task is well understood prior to performing it much of the activity can be preplanned. If it is n~t understood, then during the actual task execution more knowledge is acquired which leads to changes in resource allocations, schedules, and priorities.”

“Political philosophy seems often to reside at a distance from the world. Principles are one thing, politics another, and even our best efforts to ‘live up’ to our ideals typically founder on the gap between theory and practice.But if political philosophy is unrealizable in one sense, it is unavoidable in another. This is the sense in which philosophy inhabits the world from the start; our practices and institutions are embodiments of theory.... for all our uncertainties about ultimate questions of political philosophy — of justice and value and the nature of the good life — the one thing we know is that we live some answer all the time.”

“Why was progress in computing technology so fast compared with the lack of progress in space travel?

“The Principle of Uncertainty is a bad name. In science, or outside of it, we are not uncertain; our knowledge is merely confined, within a certain tolerance. We should call it the Principle of Tolerance. And I propose that name in two senses. First, in the engineering sense: Science has progressed, step by step, the most successful enterprise in the ascent of man, because it has understood that the exchange of information between man and nature, and man and man, can only take place with a certain tolerance. But second, I also use the word, passionately, about the real world. All knowledge – all information between human beings – can only be exchanged within a play of tolerance. And that is true whether the exchange is in science, or in literature, or in religion, or in politics, or in any form of thought that aspires to dogma. It's a major tragedy of my lifetime and yours that scientists were refining, to the most exquisite precision, the Principle of Tolerance – and turning their backs on the fact that all around them, tolerance was crashing to the ground beyond repair. The Principle of Uncertainty or, in my phrase, the Principle of Tolerance, fixed once for all the realization that all knowledge is limited. It is an irony of history that at the very time when this was being worked out, there should rise, under Hitler in Germany and other tyrants elsewhere, a counter-conception: a principle of monstrous certainty. When the future looks back on the 1930's, it will think of them as a crucial confrontation of culture as I have been expounding it – the ascent of man against the throwback to the despots' belief that they have absolute certainty.”

“We sleep in peace in the arms of God when we yield ourselves up to His providence, in a delightful consciousness of His tender mercies; no more restless uncertainties, no more anxious desires, no more impatience at the place we are in, for it is God who has put us there, and who holds us in His arms. Can we be unsafe where He has placed us, and where He watches over us as a parent watches a child? This confiding repose, in which earthly care sleeps, is the true vigilance of the heart; yielding itself up to God, with no other support than Him, it thus watches while we sleep. This is the love of Him that will not sleep even in death.”
