Flimsy Solution Conviction

“In the case of a real design problem, even our conviction that there is such a thing as fit to be achieved is curiously flimsy and insubstantial. We are searching for some kind of harmony between two intangibles: a form which we have not yet designed, and a context which we cannot properly describe. The only reason we have for thinking that there must be some kind of fit to be achieved between them is that we can detect incongruities, or negative instances of it.”

Thomas_Aquinas

Reason

“Reason may be employed in two ways to establish a point: first for the purpose of furnishing sufficient proof of some principle, as in natural science, where sufficient proof can be brought to show that the movement of the heavens is always of uniform velocity. Reason is employed in another way, not as furnishing a sufficient proof of a principle, but as confirming an already established principle, by showing the congruity of its results, as in astrology the theory of eccentrics and epicycles is considered as established because thereby the sensible appearances of the heavenly movements can be explained; not, however, as if this reason were sufficient, since some other theory might explain them.”

Isaac_Asimov

Evidence

“I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.”

Francis_Bacon

Axioms

“It cannot be that axioms established by argumentation should avail for the discovery of new works, since the subtlety of nature is greater many times over than the subtlety of argument. But axioms duly and orderly formed from particulars easily discover the way to new particulars, and thus render sciences active.”

Jim_Baggott

The Reality Principle

“The Reality Principle. Reality is a metaphysical concept, and as such it is beyond the reach of science. Reality consists of things-in-themselves of which we can never hope to gain knowledge. Instead, we have to content ourselves with knowledge of empirical reality, of things-as-they-appear or things-as-they-are-measured. Nevertheless, scientific realists assume that reality (and its entities) exists objectively and independently of perception or measurement. They believe that reality is rational, predictable and accessible to human reason.”

Tainted Fact Reason

“Reasoning will always be correct when applied to accurate notions and precise facts; but it can lead only to error when the notions or facts on which it rests were originally tainted with error or inaccuracy.”

Observer and Experimenter

“The observer does not reason, he notes; the experimenter, on the other hand, reasons and grounds himself on acquired facts, to imagine and induce rationally other facts. But though in theory and abstractly we may differentiate observers from experimenters, it seems impossible to separate them in practice.”

Hypothesis Theory Reason

“A scientific hypothesis is merely a scientific idea, preconceived or pre-visioned. A theory is merely a scientific idea controlled by experiment. Reasoning merely gives a form to our ideas, so that everything, first and last, leads back to an idea.”

Trust

“The great experimental principle, then, is doubt... We must trust our observations or our theories only after experimental verification. If we trust too much, the mind becomes bound and cramped by the results of its own reasoning; it no longer has freedom of action, and so lacks the power to break away from that blind faith in theories which is only scientific superstition.”

David_Bohm

Extraphysical Principles

“There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses. For the history of scientific research is full of examples in which it was very fruitful indeed to assume that certain objects or elements might be real, long before any procedures were known which would permit them to be observed directly.”

Dietrich_Bonhoeffer

Stupidity

“Stupidity is a more dangerous enemy of the good than malice. One may protest against evil; it can be exposed and, if need be, prevented by use of  force. Evil always carries within itself the germ of its own subversion in that it leaves behind in human beings at least a sense of unease. Against stupidity we are defenseless. Neither protests nor the use of force accomplish anything here; reasons fall on deaf ears; facts that contradict one’s prejudgment simply need not be believed — in such moments the stupid person even becomes critical — and when facts are irrefutable they are just pushed aside as inconsequential, as incidental. In all this the stupid person, in contrast to the malicious one, is utterly self-satisfied and, being easily irritated, becomes dangerous by going on the attack. For that reason, greater caution is called for when dealing with a stupid person than with a malicious one. Never again will we try to persuade the stupid person with reasons, for it is senseless and dangerous.”

Software Complexity

“Einstein repeatedly argued that there must be simplified explanations of nature, because God is not capricious or arbitrary. No such faith comforts the software engineer. Much of the complexity he must master is arbitrary complexity, forced without rhyme or reason by the many human institutions and systems to which his interfaces must conform. These differ from interface to interface, and from time to time, not because of necessity but only because they were designed by different people, rather than by God.”

Scientific Study

"In scientific study, or, as I prefer to phrase it, in creative scholarship, the truth is the single end sought; all yields to that. The truth is supreme, not only in the vague mystical sense in which that expression has come to be a platitude, but in a special, definite, concrete sense. Facts and the immediate and necessary inductions from facts displace all pre-conceptions, all deductions from general principles, all favourite theories. Previous mental constructions are bowled over as childish play-structures by facts as they come rolling into the mind. The dearest doctrines, the most fascinating hypotheses, the most cherished creations of the reason and of the imagination perish from a mind thoroughly inspired with the scientific spirit in the presence of incompatible facts. Previous intellectual affections are crushed without hesitation and without remorse. Facts are placed before reasonings and before ideals, even though the reasonings and the ideals be more beautiful, be seemingly more lofty, be seemingly better, be seemingly truer. The seemingly absurd and the seemingly impossible are sometimes true. The scientific disposition is to accept facts upon evidence, however absurd they may appear to our pre-conceptions."

Autotelic

“The key element of an optimal experience is that it is an end in itself. Even if initially undertaken for other reasons, the activity that consumes us becomes intrinsically rewarding... When the experience is autotelic, the person is paying attention to the activity for its own sake; when it is not, the attention is focused on its consequences.”

Writing

“It is never a waste to write for intrinsic reasons. First of all, writing gives the mind a disciplined means of expression. It allows one to record events and experiences so that they can be easily recalled, and relived in the future. It is a way to analyze and understand experiences, a self-communication that brings order to them.”

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."

Effective Reasoning

“The required techniques of effective reasoning are pretty formal, but as long as programming is done by people that don't master them, the software crisis will remain with us and will be considered an incurable disease. And you know what incurable diseases do: they invite the quacks and charlatans in, who in this case take the form of Software Engineering gurus.”

Experts and Amateurs

Only trained experts can do experiments with the care and precision that experiments demand. Expert experimenters are not infallible, but they are less fallible than amateurs.”

Albert_Einstein

Intuition and Inspiration

“I believe in intuition and inspiration. ... At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.”

Questioning

“The important thing is not to stop questioning. Curiosity has its own reason for existence. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality.

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.”

All Problems Technical

“Basically, all problems are technical. If you know what you want to do and you have the necessary technical background, there is no point in making a great management problem out of it. Obviously, a certain amount of resource control and personnel work has to go on but that’s all. On the other hand, you might have a task which is difficult in that you don’t know what you have to do, and that even if you did you wouldn’t know how to do it. Since this is a very difficult task you can start out with the hypothesis that it will take a great number of people. Following down this slippery slope of reasoning, as soon as you have a very large number of people you have a very large management problem. But it all originated out of the fact that you didn’t know what you were doing, or how to do it.”

Closer Reality

“The foundations of physics give us a closer look at reality, but the closer we look at reality, the more slippery it becomes. Our heavy use of mathematics is a major reason. The more the fundamental descriptions of nature have become divorced from our everyday experience, the more we must rely on mathematical rigor. This reliance has consequences. Using math to describe reality means that the same observations can be equivalently explained in many different ways. That’s just because there are many sets of mathematical axioms that will give the exact same predictions for all available data. Thus, if you want to assign 'reality' to one of your explanations, you won’t know which.”

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.”

Slow Progress

“From the earliest times of which we have record — back, say, to two thousand years before Christ [BCE 2000] down to the beginning of the eighteenth century [CE 1700] — there was no very great change in the standard of life of the average man living in the civilised centres of the earth... This slow rate of progress, or lack of progress, was due to two reasons — to the remarkable absence of important technical improvements and to the failure of capital to accumulate.”

The justification of such a mathematical construct is solely and precisely that it is expected to work — that is, correctly to describe phenomena from a reasonably wide area.”

Qubit Information Capacity

“Is there a fundamental reason why quantum computers cannot factor large integers used for encryption today? We introduce a concept called Qubit Information Capacity which arises if the continuum nature of quantum mechanics’ state space is an approximation for something inherently discrete. We argue that the physical reason for such discreteness is gravity. Based on this, we predict that quantum computers will never be able to break realistic RSA-encrypted messages.”

Pascal's Wager

“A game is on, at the other end of this infinite distance, and heads or tails will turn up. What will you wager? According to reason you cannot leave either; according to reason you cannot leave either undone... Yes, but wager you must; there is no option, you have embarked on it. So which will you have. Come. Since you must choose, let us see what concerns you least. You have two things to lose: truth and good, and two things to stake: your reason and your will, your knowledge and your happiness. And your nature has two things to shun: error and misery. Your reason does not suffer by your choosing one more than the other, for you must choose. That is one point cleared. But your happiness? Let us weigh gain and loss in calling heads that God is. Reckon these two chances: if you win, you win all; if you lose, you lose naught. Then do not hesitate, wager that He is.”

Neurons to Consciousness

“None of us has a brain that can actually put us in touch with reality unaided with truth. I've just shown you a bunch of gadgetry that responds to things that are essential to our survival, things that prevent us from falling off cliffs and bumping into trees. But they don't actually correspond to any clear description of the world as it is. So we have, for example, circuitry that responds to the edges rather than the physical distribution of light, because edges are important, that's where objects leave off and their backgrounds begin. Moreover, they can be fooled, as I did with each one of you. That since our neural circuitry does consist of a mechanism, not a pipeline to the truth or a window onto objective reality. That is naïve realism we know is false because there are illusions. You can't just trust your senses. That means we need some way of augmenting the faculties that nature gave us to make our beliefs as accurate as possible. Which of course is why the early modern philosophers made such a big deal of visual illusions. They said you can't just open your eyes and see the world as it is. Look at all these illusions. So what we do, what gives some of us confidence that our beliefs are objectively true is that they are part of an institutional infrastructure of testing and criticism and logic and determining which hypotheses withstand criticism and attempts at refutation. Devising exotic arrangements of reality to reflect the way reality is put together, namely experiments. Thanks to this huge network of minds, each one of them making up for deficits of all the others, we like to think that we have a collective grasp on truth that none of us individually can have. But of course, it's always fallible. The religious beliefs I think were actually pretty reasonable hypotheses in earlier states of our collective knowledge. Even Richard Dawkins said that before Darwin he probably would have been a creationist because the cosmic engineer was the only available explanation for the obvious adaptive complexity of living things. I would add that prior to the advent of modern neuroscience I probably would have believed in souls because there was no better explanation for phenomena such as that people respond intelligently to their environments. When you dream some part of you is up and about the world while your body is in bed the whole time. That seems like there must be some part of you that can leave your body. When a person suddenly dies some kind of animating force no longer seems to be animating the body that was there just a few minutes ago. So the soul hypothesis is not a stupid or irrational belief, nor is creationism if it's the best that you have. Now, of course, we can do better. But doing better in part depends not just on this cumulative weight of evidence and argument. But because few of us can actually reconstruct the scientific observations that justify the theory of natural selection or the theory of neural networks, all of us, at least a little bit, take it on faith in the following sense; that there is a community that you trust enough because when they have been challenged to defend their beliefs they can connect them to reality. They have shown that it isn't magic. That they have given reason to trust them because they've convinced you that they're the mores of their culture, of their scientific culture, designed so that they will find true things and weed out false things. If you don't have a degree of solidarity or trust, if you think that scientists are all in cahoots with big corporations or are trying to tear down all faith and values and meaning and you simply refuse to follow through the very long chain of deduction that connects the claims to the experiments, then you'll naturally reject it just because it's not your tribe. For you and me scientists are our tribe and we're apt to give them some credibility, indeed some credulousness, knowing that if ever challenged it would be repaid. But unless you trace that through it can be all too easy to reject the conclusions of science, and indeed a number of studies have shown that contrary to the common belief that people believe in falsehoods, such as that vaccines cause autism or that humans were created five thousand years ago or that the burning of fossil fuels has no effect on global temperatures, it turns out that people with those beliefs that we have every reason to believe are false are no more scientifically naïve on average than people that have beliefs that are scientifically justified. You give a test on evolution to a bunch of people who believe in evolution, give it to a bunch of creationists, there's not much difference in how well they score. In fact, often they are equal. Likewise, the typical grasp of climate science among someone who signs on to the scientific consensus is not much better than the adamant deniers. That kind of dashes the hope that simply by increasing the quality of science education you will lead people to more accurate beliefs. There, in addition, has to be a dissociation of who you think are the good guys and who are the bad guys from who has the best claims to truth. That's what it depends on.”

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'.”

Markets and Coordination

“Markets aim to coordinate the decisions and behavior of multitudes of economic actors to guarantee that the quantity of brussels sprouts shipped to market bears some reasonable relation to the quantity that consumers will buy and eat, and that the price at which brussels sprouts can be sold bears a reasonable relation to the cost of producing them. Any society that is not a subsistence economy, but has substantial specialization and division of labor, needs mechanisms to perform this coordinative function. Markets are only one, however, among the spectrum of mechanisms of coordination on which any society relies. [central planning, bargaining and negotiation, business, government, education, balloting procedures]”

Baruch_Spinoza

Good and Evil

“Experience day by day protested and showed by infinite examples, that good and evil fortunes fall to the lot of pious and impious alike; still they would not abandon their inveterate prejudice, for it was more easy for them to class such contradictions among other unknown things of whose use they were ignorant, and thus to retain their actual and innate condition of ignorance, than to destroy the whole fabric of their reasoning and start afresh. They therefore laid down as an axiom, that God's judgments far transcend human understanding. Such a doctrine might well have sufficed to conceal the truth from the human race for all eternity, if mathematics had not furnished another standard of verity in considering solely the essence and properties of figures without regard to their final causes.”

Explanations

“Very many controversies have arisen from the fact, that men do not rightly explain their meaning, or do not rightly interpret the meaning of others. For, as a matter of fact, as they flatly contradict themselves, they assume now one side, now another, of the argument, so as to oppose the opinions, which they consider mistaken and absurd in their opponents.”

Great Difficulty with Good Hypothesis

“There is one great difficulty with a good hypothesis. When it is completed and rounded, the corners smooth and the content cohesive and coherent, it is likely to become a thing in itself, a work of art. It is then like a finished sonnet or a painting completed. One hates to disturb it. Even if subsequent information should shoot a hole in it, one hates to tear it down because it once was beautiful and whole. One of our leading scientists, having reasoned a reef in the Pacific, was unable for a long time to reconcile the lack of a reef, indicated by soundings, with the reef his mind told him was there.”

Rigid Dogma Destroys Truth

“It is rigid dogma that destroys truth; and, please notice, my emphasis is not on the dogma, but on the rigidity. When men say of any question, ‘This is all there is to be known or said of the subject; investigation ends here,' that is death. It may be that the mischief comes not from the thinker but for the use made of his thinking by late-comers. Aristotle, for example, gave us our scientific technique ... yet his logical propositions, his instruction in sound reasoning which was bequeathed to Europe, are valid only within the limited framework of formal logic, and, as used in Europe, they stultified the minds of whole generations of medieval Schoolmen. Aristotle invented science, but destroyed philosophy.”

Animality

“The close relationship between the rejection of animality and the progress of civilization is at the heart of our modern conception of work. Marx expressed this relationship when he argued that mastery of the material world was the basis upon which man humanized himself and developed culture. This in fact is the civilizing process; humanization means tempering animality with rationality, aesthetic grace, and moral choice.”

Frederick Taylor

“The man who emerged as the chief symbol of the rational approach to management was Frederick Taylor. Though much has been written on Taylor and the philosophy and methods of scientific management, it is worth highlighting a few central themes for three reasons. First, Taylorism explicitly treats the worker's body in its two dimensions -- as a source of effort and as a source of skill. Second, workers' responses to Taylorism reveal the ambivalence that this dual role of the body can create, as it did among the bleach plant operators or the nineteenth-century glassmakers. Third, the logic that motivated the early purveyors and adapters of scientific management has continued to dominate the course of automation in the twentieth-century workplace. As will be argued later, it is a logic that must undergo a fundamental reevaluation as information technology is widely adapted to productive activity.”

Know-How

“The agenda for scientific management was to increase productivity by streamlining and rationalizing factory operation from cost accounting and supervision to the dullest job on the shop floor. Efficiency was the mania, and to achieve efficiency, it would be necessary to penetrate the labor process and force it to yield up its secrets. In order that effort be rationalized, the worker's skills had to be made explicit. In many cases, workers' perceptions of their own interests prevented them from articulating their know-how, but there was yet another involuntary barrier. These skills did not easily yield themselves to explication; they were embedded in the ways of the body, in the knacks and know-how of the craftworker.”

Time Study Expert

“The time-study expert became the new focus of workers' antagonisms. Informal production quotas persisted and, in many cases, took on an overtly anti-management spirit. The union contract became the most important means for institutionalizing workers' instincts for self-preservation, as rationalization routed out the ordinary graces with which the workday had been laced. Concern over wages and hours, work rules, and working conditions began to replace the craftworker's culturally embedded practices of effort regulation. Overall, the purification of effort meant a heightened standard of labor discipline, and as such it widened the gulf between those who gave of their bodies in the service of production and those who did not.”

Universal Transparency
