Physics and Human Experience

“Physics is to be regarded not so much as the study of something given a priori, but rather as the development of methods for ordering and surveying human experience.”

Dietrich_Bonhoeffer

Contempt for Humanity

“The danger of allowing ourselves to be driven to contempt for humanity is very real... Whoever despises another human being will never be able to make anything of him. Nothing of what we despise in another is itself foreign to us.”
  • Source: From the paper “An Account at the Turn of the Year 1942-1943” by Dietrich Bonhoeffer, contained within the book “Dietrich Bonhoeffer: Volume 8: Letters and Papers from Prison” edited by John W. Gruchy, et al. Published in 2009 by Fortress Press.

Max_Born

Experience and Knowledge

“But in practical affairs, particularly in politics, men are needed who combine human experience and interest in human relations with a knowledge of science and technology. Moreover, they must be men of action and not contemplation. I have the impression that no method of education can produce people with all the qualities required. I am haunted by the idea that this break in human civilization, caused by the discovery of the scientific method, may be irreparable.”

George_E_P_Box

Slow Progress

“History shows that the human animal has always learned but progress used to be very slow. This was because learning often depended on the chance coming together of a potentially informative event on the one hand and a perceptive observer on the other. Scientific method accelerated that process.”

Consciousness

“Consciousness is a word created by humans, in this case English-speaking humans, to describe something humans know nothing about.”

Human Element

“The real scoop on programming and software is the human element. I didn't know Alan Turing or John von Neuman or the other inventors, but I've known plenty of programmers. We are just like everyone, part this, part that. Except we have to deal with enormous complexity, which springs upon us only after we are too far into what started out to be kind of fun - coding an algorithm and watching it run on a machine. Then it's too late and it all becomes work, very stressful work.”

Society Complex

“It is sheer nonsense to expect that any human being has yet been able to attain such insight into the problems of society that he can really identify the central problems and determine how they should be solved. The systems in which we live are far too complicated as yet for our intellectual powers and technology to understand.”

William_Kingdon_Clifford

Insufficient Evidence

"To sum up: it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence. If a man, holding a belief which he was taught in childhood or persuaded of afterwards, keeps down and pushes away any doubts which arise about it in his mind, purposely avoids the reading of books and the company of men that call into question or discuss it, and regards as impious those questions which cannot easily be asked without disturbing it-- the life of that man is one long sin against mankind."

The Light Is Better There

“The main reason we tend to focus on the technical rather than the human side of the work is not because it’s more crucial, but because it’s easier to do. Getting the new disk drive installed is positively trivial compared to figuring out why Horace is in a blue funk or why Susan is dissatisfied with the company after only a few months. Human interactions are complicated and never very crisp and clean in their effects, but they matter more than any other aspect of the work. If you find yourself concentrating on the technology rather than the sociology, you’re like the vaudeville character who loses his keys on a dark street and looks for them on the adjacent street because, as he explains, ‘The light is better there.’”

Cheeseburgers

"Development is inherently different from production. But managers of development and allied efforts often allow their thinking to be shaped by a management philosophy derived entirely from a production environment.
Imagine for the moment that you’re the manager of the local fast food franchise. It makes perfect sense for you to take any or all of the following efficient production measures:
- Squeeze out error. Make the machine (the human machine) run as smoothly as possible.
- Take a hard line about people goofing off on the job.
- Treat workers as interchangeable pieces of the machine.
- Optimize the steady state. (Don’t even think about how the operation got up to speed, or what it would take to close it down.)
- Standardize procedure. Do everything by the book.
- Eliminate experimentation—that’s what the folks at headquarters are paid for.
These would be reasonable approaches if you were in the fast food business (or any production environment), but you’re not. The 'make a cheeseburger, sell a cheeseburger' mentality can be fatal in your development area. It can only serve to damp your people’s spirits and focus their attention away from the real problems at hand. This style of management will be directly at odds with the work.
To manage thinking workers effectively, you need to take measures nearly opposite those listed above."

Freeman_Dyson

Science and Society

“In the modern world, science and society often interact in a perverse way. We live in a technological society, and technology causes political problems. The politicians and the public expect science to provide answers to the problems. Scientific experts are paid and encouraged to provide answers. The public does not have much use for a scientist who says, 'Sorry, but we don’t know.' The public prefers to listen to scientists who give confident answers to questions and make confident predictions of what will happen as a result of human activities. So it happens that the experts who talk publicly about politically contentious questions tend to speak more clearly than they think. They make confident predictions about the future, and end up believing their own predictions. Their predictions become dogmas which they do not question. The public is led to believe that the fashionable scientific dogmas are true, and it may sometimes happen that they are wrong. That is why heretics who question the dogmas are needed.”

Albert_Einstein

Magnificent Applied Science

“Why does this magnificent applied science which saves work and makes life easier bring us so little happiness? The simple answer runs: Because we have not yet learned to make sensible use of it. In war it serves that we may poison and mutilate each other. In peace it has made our lives hurried and uncertain. Instead of freeing us in great measure from spiritually exhausting labor, it has made men into slaves of machinery, who for the most part complete their monotonous long day's work with disgust and must continually tremble for their poor rations... It is not enough that you should understand about applied science in order that your work may increase man's blessings. Concern for the man himself and his fate must always form the chief interest of all technical endeavours; concern for the great unsolved problems of the organization of labor and the distribution of goods in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.”

Science Objective and Subjective

“Science as something already in existence, already completed, is the most objective, impersonal thing that we humans know. Science as something coming into being, as a goal, is just as subjectively, psychologically conditioned as are all other human endeavors.”

Man Thinking

“The scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men's thinking.”

Richard_Feynman

Unlike Ordinary Experience

“Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to and it appears peculiar and mysterious to everyone, both to the novice and to the experienced physicist. Even the experts do not understand it the way they would like to, and it is perfectly reasonable that they should not, because all of direct, human experience and of human intuition applies to large objects. We know how large objects will act, but things on a small scale just do not act that way. So we have to learn about them in a sort of abstract or imaginative fashion and not by connection with our direct experience.”

Drudgery

Engineer Thinking

“They felt that they were improving the world, not only by their deeds, but also by their way of thinking.

Engineers and Designers Are Human

“Throughout this book we have talked about 'designers' and 'engineers' and sought, by analysing their work, to find general and helpful maxims. But there is a danger in doing this, for we may forget that a 'designer' or 'engineer' is first and foremost a human being. A human being who designs or engineers has, in addition, a wide range of complicated and interacting emotions. It is easy to become emotionally involved in a new invention and so resent criticism of it even when that criticism, if heeded, would turn a failure into a success. Confidence may be blinded by conceit or undermined by an inferiority complex. History has shown that many new inventions were not inventions at all; they were re-inventions. The idea was not new but the determination to press through with it was. Character is the foundation of ability. Develop as large a safety margin as you can against such things as laziness, impatience, prejudice and arrogance and all the other human failings that inhibit constructive achievement in all spheres, especially that of creative engineering design.”

Artificial Intelligence

Religion and Science

“I am not opposed to religious belief. Science has limits, and yet humanity has always sought meaning beyond those limits. Some do it by studying holy scripture, some meditate, some dig philosophy, some smoke funny things. That’s all fine with me, really. Provided that—and here’s the crux—your search for meaning respects scientific fact. If your belief conflicts with empirically confirmed knowledge, then you are not seeking meaning; you are delusional.”

Fact Driven

“Humans are not by nature the fact-driven, rational beings we like to think we are. We get the facts wrong more often than we think we do. And we do so in predictable ways: we engage in wishful thinking. We embrace information that supports our beliefs and reject evidence that challenges them. Our minds tend to take shortcuts, which require some effort to avoid ... [and] more often than most of us would imagine, the human mind operates in ways that defy logic.”

Psychological Experiments

“Psychological experiments have shown ... that humans tend to seek out even weak evidence to support their existing beliefs, and to ignore evidence that undercuts those beliefs. In the process, we apply stringent tests to evidence we don't want to hear, while letting slide uncritically into our minds any information that suits our needs.”

Carl_Jung

Insoluble Problems

“I always worked with the temperamental conviction that fundamentally there are no insoluble problems, and experience justified me in so far as I have often seen individuals simply outgrow a problem which had destroyed others. This ‘outgrowing’, as I formerly called it, on further experience was seen to consist in a new level of consciousness. Some higher or wider interest arose on the person's horizon, and through this widening of his view the insoluble problem lost its urgency. It was not solved logically in its own terms, but faded out when confronted with a new and stronger life-tendency. It was not repressed and made unconscious, but merely appeared in a different light, and so did indeed become different. What, on a lower level, had led to the wildest conflicts and to panicky outbursts of emotion, viewed from the higher level of the personality, now seemed like a storm in the valley seen from a high mountain-top. This does not mean that the thunderstorm is robbed of its reality, but instead of being in it, one is now above it. However, since we are both valley and mountain with respect to the psyche, it might seem a vain illusion to feel oneself beyond what is human. One certainly does feel the affect and is shaken and tormented by it, yet at the same time one is aware of a higher consciousness, which prevents one from becoming identical with the affect, a consciousness which takes the affect objectively, and can say, Ί know that I suffer'.”

Sad Truth

“The sad truth is that man's real life consists of a complex of inexorable opposites — day and night, birth and death, happiness and misery, good and evil. We are not even sure that one will prevail against the other, that good will overcome evil, or joy defeat pain. Life is a battleground. It always has been, and always will be; and if it were not so, existence would come to an end.”

Greatest Danger

Laws and Teachings

“Laws and teachings held in common compel people to solitude, so that they may escape the pressure of undesirable contact, but solitude makes people hostile and venomous. Therefore give people dignity and let each of them stand apart, so that each may find his own fellowship and love it. Power stands against power, contempt against contempt, love against love. Give humanity dignity, and trust that life will find the better way.”

Technological Unemployment

“In our own lifetimes... we may be able to perform all the operations of agriculture, mining, and manufacture with a quarter of the human effort to which we have been accustomed. For the moment the very rapidity of these changes is hurting us and bringing difficult problems to solve... We are being afflicted with... technological unemployment. This means unemployment due to our discovery of means of economising the use of labour outrunning the pace at which we can find new uses for labour. But this is only a temporary phase of maladjustment... In the long run... mankind is solving its economic problem. I would predict that the standard of life in progressive countries one hundred years hence will be between four and eight times as high as it is today.”

Traditional Purpose

“Thus, we have been expressly evolved by nature — with all our impulses and deepest instincts — for the purpose of solving the economic problem. If the economic problem is solved, mankind will be deprived of its traditional purpose. Will this be a benefit? If one believes at all in the real values of life, the prospect at least opens up the possibility of benefit. Yet I think with dread of the readjustment of the habits and instincts of the ordinary man, bred into him for countless generations, which he may be asked to discard within a few decades.”

Pierre-Simon_Laplace

System of Nature

“The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence that at a given instant comprehends all the relations of the entities of this universe, it could state the respective position, motions, and general affects of all these entities at any time in the past or future. Physical astronomy, the branch of knowledge that does the greatest honor to the human mind, gives us an idea, albeit imperfect, of what such an intelligence would be. The simplicity of the law by which the celestial bodies move, and the relations of their masses and distances, permit analysis to follow their motions up to a certain point; and in order to determine the state of the system of these great bodies in past or future centuries, it suffices for the mathematician that their position and their velocity be given by observation for any moment in time. Man owes that advantage to the power of the instrument he employs, and to the small number of relations that it embraces in its calculations. But ignorance of the different causes involved in the production of events, as well as their complexity, taken together with the imperfection of analysis, prevents our reaching the same certainty about the vast majority of phenomena. Thus there are things that are uncertain for us, things more or less probable, and we seek to compensate for the impossibility of knowing them by determining their different degrees of likelihood. So it was that we owe to the weakness of the human mind one of the most delicate and ingenious of mathematical theories, the science of chance or probability.”

Thomas_Robert_Malthus

Population and Subsistence

“I think I may fairly make two postulata. First, That food is necessary to the existence of man. Secondly, That the passion between the sexes is necessary, and will remain nearly in its present state... Assuming then my postulata as granted, I say, that the power of population is indefinitely greater than the power in the earth to produce subsistence for man. Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio... This implies a strong and constantly operating check on population from the difficulty of subsistence. This difficulty must fall somewhere; and must necessarily be severely felt by a large portion of mankind... The germs of existence contained in this spot of earth, with ample food, and ample room to expand in, would fill millions of worlds in the course of a few thousand years... Consequently, if the premises are just, the argument is conclusive against the perfectibility of the mass of mankind.”

Condorcet and Other Writers”. Originally published: 1798. Edition: First. Publisher: J. Johnson. Location: London, England. Chapter: 1. Retrieved From: <https://en.wikisource.org/wiki/An_Essay_on_the_Principle_of_Population>. Retrieval Date: 2024-04-03.
  • Notes: The dire predictions of Malthus have not yet been fulfilled. This is primarily due to errors in his initial assumptions (which are properly identified), not in errors in his logic. The first assumption (or postulatum) is that food production increases arithmetically (linearly). But historically, food production has increased geometrically (exponentially) due to advances in mechanical technologies and biotechnologies. The second assumption assumes passion and birth rates are directly correlated. However, technological advances in birth control, cultural advances in women's rights, and rising prosperity (which lowers birth rates) have falsified this assumption. Additional questionable assumptions are also made which are not initially specified.

Karl_Marx

Religion

“Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people. The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo. Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower.”

Abraham_Maslow

Selfhood

“...it is reasonable to assume in practically every human being... there is an active will towards health, an impulse towards growth, or toward the actualization of human potentialities.

Morality

“It was morality that burned the books of the ancient sages, and morality that halted the free inquiry of the Golden Age and substituted for it the credulous imbecility of the Age of Faith. It was a fixed moral code and a fixed theology which robbed the human race of a thousand years by wasting them upon alchemy, heretic-burning, witchcraft and sacerdotalism.”

Gravity

“It is inconceivable that inanimate matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact... That gravity should be innate, inherent and essential to matter, so that one body may act upon another at a distance thro' a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity that I believe no man who has in philosophical matters a competent faculty of thinking can ever fall into it. Gravity must be caused by an agent acting constantly according to certain laws; but whether this agent be material or immaterial, I have left to the consideration of my readers.”

Human Communication Limits

“A man can communicate with about five colleagues on a software project without too much difficulty. Likewise he can supervise about five people and know pretty well what they are doing.

Scientific Method Elucidation

“Almost every major systematic error which has deluded men for thousands of years relied on practical experience. Horoscopes, incantations, oracles, magic, witchcraft, the cures of witch doctors and of medical practitioners before the advent of modern medicine, were all firmly established through the centuries in the eyes of the public by their supposed practical successes. The scientific method was devised precisely for the purpose of elucidating the nature of things under more carefully controlled conditions and by more rigorous criteria than are present in the situations created by practical problems.”

Theory Personality

“Understanding a theory has, indeed, much in common with understanding a human personality. We may know or understand a man's system of dispositions pretty well; that is to say, we may be able to predict how he would act in a number of different situations. But since there are infinitely many possible situations, of infinite variety, a full understanding of a man's dispositions does not seem to be possible.”

Science Not Certain

“Science is not a system of certain, or established, statements; nor is it a system which steadily advances towards a state of finality... And our guesses are guided by the unscientific, the metaphysical (though biologically explicable) faith in laws, in regularities which we can uncover — discover. Like Bacon, we might describe our own contemporary science — 'the method of reasoning which men now ordinarily apply to nature' — as consisting of 'anticipations, rash and premature' and as 'prejudices'.”

Irresponsible Dreams

“The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there. In most other fields of human endeavour there is change, but rarely progress ... And in most fields we do not even know how to evaluate change.”

Exact Science Approximate

“Although this may seem a paradox, all exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man. Every careful measurement in science is always given with the probable error ... every observer admits that he is likely wrong and knows about how much wrong he is likely to be.”

Changing Opinion

“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”

Scientific Progress

“No history of civilization can be tolerably complete which does not give considerable space to the explanation of scientific progress. If we had any doubts about this, it would suffice to ask ourselves what constitutes the essential difference between our and earlier civilizations. Throughout the course of history, in every period, and in almost every country, we find a small number of saints, of great artists, of men of science. The saints of today are not necessarily more saintly than those of a thousand years ago; our artists are not necessarily greater than those of early Greece; they are more likely to be inferior; and of course, our men of science are not necessarily more intelligent than those of old; yet one thing is certain, their knowledge is at once more extensive and more accurate. The acquisition and systematization of positive knowledge is the only human activity which is truly cumulative and progressive. Our civilization is essentially different from earlier ones, because our knowledge of the world and of ourselves is deeper, more precise, and more certain, because we have gradually learned to disentangle the forces of nature, and because we have contrived, by strict obedience to their laws, to capture them and to divert them to the gratification of our own needs.”

Knowledge Came Slowly

“In ages past, the knowledge came very slowly, and one man in his life was not likely to see much change other than that wrought by nature. The controlled incorporation of arsenic into copper to make bronze took several thousand years to develop; the substitution of tin for the more dangerous arsenic took another thousand or two. In our modern age, laboratories turn out an alloy a day, or more, with properties made to order. The alloying of metals led to the rise and fall of civilizations, but the changes were too slow to be appreciated. A truer blade meant victory over the invaders, but changes were local and slow enough to be absorbed by a million tiny adjustments without destroying the species. With an alloy a day, we can no longer be sure. Science and engineering have been the catalysts for the unprecedented speed and magnitude of change. The physicist shows us how to harness the power of the nucleus; the chemist shows us how to increase the quantity of our food; the geneticist shows us how to improve the quality of our children. But science and engineering have been unable to keep pace with the second-order effects produced by their first-order victories. The excess heat from the nuclear generator alters the spawning pattern of fish, and, before adjustments can be made, other species have produced irreversible changes in the ecology of the river and its borders. The pesticide eliminates one insect only to the advantage of others that may be worse, or the herbicide clears the rain forest for farming, but the resulting soil changes make the land less productive than it was before. And of what we are doing to our progeny, we still have only ghastly hints. Some have said the general systems movement was born out of the failures of science, but it would be more accurate to say the general systems approach is needed because science has been such a success. Science and technology have colonized the planet, and nothing in our lives is untouched. In this changing, they have revealed a complexity with which they are not prepared to deal. The general systems movement has taken up the task of helping scientists unravel complexity, technologists to master it, and others to learn to live with it.”

Egoless Programming and John von Neumann

“Programming groups who have conquered the ego problem do exist and have existed from the earliest days of computing. John von Neumann himself was perhaps the first programmer to recognize his inadequacies with respect to examination of his own work. Those who knew him have said that he was constantly asserting what a lousy programmer he was, and that he incessantly pushed his programs on other people to read for errors and clumsiness. Yet the common image today of von Neumann is of the unparalleled computing genius — flawless in his every action. And indeed, there can be no doubt of von Neumann's genius. His very ability to realize his human limitations put him head and shoulders above the average programmer today. Average people can be trained to accept their humanity — their inability to function like a machine — and to value it and work with others so as to keep it under the kind of control needed if programming is to be successful.”

Science Accuracy Certainty

“Science would have us believe that such accuracy, leading to certainty, is the only criterion of knowledge, would make the trial of Galileo the paradigm of the two points of view which aspire to truth, would suggest, that is, that the cardinals represent only superstition and repression, while Galileo represents freedom. But there is another criterion which is systematically neglected in this elevation of science. Man does not now — and will not ever — live by the bread of scientific method alone. He must deal with life and death, with love and cruelty and despair, and so must make conjectures of great importance which may or may not be true and which do not lend themselves to experimentation: It is better to give than to receive; Love thy neighbor as thyself; Better to risk slavery through non-violence than to defend freedom with murder. We must deal with such propositions, must decide whether they are true, whether to believe them, whether to act on them — and scientific method is no help for by their nature these matters lie forever beyond the realm of science.”

Panopticon Surveillance

“At each level of these organizations, people searched for ways to adapt to the intense illumination of the information panopticon. There was less room for interpersonal ploys or negotiated solutions and fewer hidden corners in which to enjoy anonymous repose or indulge in overtly negative behavior.

Panoptic Power

“This rendering of panoptic power reflects an important evolution of the original concept. It rests on a new collectivism in which ‘the many' view themselves and each views ‘the other.' Horizontal visibility is created even as vertical visibility is intensified. The model is less one of Big Brother than of a workplace in which each member is explicitly empowered as his or her fellow worker's keeper. Instead of a single omniscient overseer, this panopticon relies upon shared custodianship of data that reflect mutually enacted behavior. This new collectivism is an important antidote to the unilateral use of panoptic power, but it is not a trouble-free ideal. Horizontal transparency breeds new human dilemmas as well.”

Learning Environment

“The demands of a learning environment can reduce the psychological distance between the self and the organization because active engagement in the social processes associated with interpretation requires more extensive participation of the human personality. In a traditional approach to work organization, employees could be treated as objectively measurable bodies, and in return, they could give of their labor without giving of their selves. The human being as wage earner and the human being as subjective actor could remain separate.”
