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.”

William_Bayliss

Mistakes

“But at the same time, there must never be the least hesitation in giving up a position the moment it is shown to be untenable. It is not going too far to say that the greatness of a scientific investigator does not rest on the fact of his having never made a mistake, but rather on his readiness to admit that he has done so, whenever the contrary evidence is cogent enough.”
  • Source: Sir William Bayliss, Principles of General Physiology (1915), x.xi.

Claude_Bernard

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.”

Role of Hypothesis

“The role of hypothesis in research can be discussed more effectively if we consider first some examples of discoveries which originated from hypotheses. One of the best illustrations of such a discovery is provided by the story of Christopher Columbus’ voyage; it has many of the features of a classic discovery in science. (a) He was obsessed with an idea—that since the world is round he could reach the Orient by sailing West, (b) the idea was by no means original, but evidently he had obtained some additional evidence from a sailor blown off his course who claimed to have reached land in the west and returned, (c) he met great difficulties in getting someone to provide the money to enable him to test his idea as well as in the actual carrying out of the experimental voyage, (d) when finally he succeeded he did not find the expected new route, but instead found a whole new world, (e) despite all evidence to the contrary he clung to the bitter end to his hypothesis and believed that he had found the route to the Orient, (f) he got little credit or reward during his lifetime and neither he nor others realized the full implications of his discovery, (g) since his time evidence has been brought forward showing that he was by no means the first European to reach America.”

House On Sand (Matthew 7:24-27)

(24) “Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:”
(25) “And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.”
(26) “And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:”
(27) “And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.'

When to Stop Testing

“Two of the great questions in developing computer systems are (1) When do we stop testing? and (2) At any point during testing, how far along are we? The second question cannot be answered until the first one has been answered. The first question can be answered by fiat.”

Faith

“It is also possible to lose oneself in systems of action that demand nothing but faith and allegiance. Fundamentalist religions, mass movements, and extremist political parties also offer opportunities for self-transcendence that millions are eager to accept. They also provide a welcome extension of the boundaries of the self, a feeling that one is involved in something great and powerful.”

Knowledge Workers

“The newly emerging dominant group is 'knowledge workers.' The very term was unknown forty years ago. (I coined it in a 1959 book, Landmarks of Tomorrow.) By the end of this century knowledge workers will make up a third or more of the work force in the United States-- as large a proportion as manufacturing workers ever made up, except in wartime. The majority of them will be paid at least as well as, or better than, manufacturing workers ever were. And the new jobs offer much greater opportunities.”

Dwight_D_Eisenhower

Crises and Balance

“Crises there will continue to be. In meeting them, whether foreign or domestic, great or small, there is a recurring temptation to feel that some spectacular and costly action could become the miraculous solution to all current difficulties. A huge increase in newer elements of our defenses; development of unrealistic programs to cure every ill in agriculture; a dramatic expansion in basic and applied research -- these and many other possibilities, each possibly promising in itself, may be suggested as the only way to the road we wish to travel. But each proposal must be weighed in the light of a broader consideration: the need to maintain balance in and among national programs, balance between the private and the public economy, balance between the cost and hoped for advantages, balance between the clearly necessary and the comfortably desirable, balance between our essential requirements as a nation and the duties imposed by the nation upon the individual, balance between actions of the moment and the national welfare of the future. Good judgment seeks balance and progress. Lack of it eventually finds imbalance and frustration.”

Giant Undertakings

“Since the 1990s, researcher Bent Flyvbjerg has kept a database that tracks giant undertakings... Only 8.5 percent of projects finished on time and on budget; 0.5 percent did that and delivered the prophesied benefits. Almost every major infrastructure project goes over budget, but at least not by as much as IT projects, which have a greater tendency to go hundreds of percent over budget. The pattern of disaster that Flyvbjerg has documented is relatively simple: With few constraints, exciting projects get too large too fast, going from big idea to giant endeavor extremely quickly.”

Great Truth

“Nothing is great but truth, and the smallest truth is great... Even a harmful truth is useful, for it can be harmful only for the moment and will lead to other truths, which must always become useful, very much so. Conversely, even a useful error is harmful, for it can be useful only for the moment, enticing us into other errors, which become more and more harmful.”

Cosmic Mind

“He [Jung] is extrapolating the natural basis for cognitive associations in the psyche to a universal basis for the organization of all events in nature.

Useful Software Systems

“We recognize that a practical problem of considerable difficulty and importance has arisen: The successful design, production and maintenance of useful software systems. The importance is obvious and the more so since we see only greater growth in demands and requirements in the future. The consequences of poor performance, poor design, instability and mismatching of promise and performance are not going to be limited to the computing fraternity, or even their nearest neighbors, but will affect considerable sections of our society whose ability to forgive is inversely proportional to their ignorance of the difficulties we face. The source of difficulty is distributed through the whole problem, easy to identify, and yet its cure is hard to pinpoint so that systematic improvement can be gotten.”

Rittel_and_Webber

Planning Problems are Wicked Problems

“A great many barriers keep us from perfecting such a planning/governing system. Theory is inadequate for decent forecasting, our intelligence is insufficient to our tasks, plurality of objectives held by pluralities of politics makes it impossible to pursue unitary aims, and so on. The difficulties attached to rationality are tenacious, and we have so far been unable to get untangled from their web. This is partly because the classical paradigm of science and engineering - the paradigm that has underlain modern professionalism - is not applicable to the problems of open societal systems.”

Science Thinking

“Science is more than a body of knowledge. It's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of the human fallibility. If we are not able to ask skeptical questions to interrogate those who tell us that something is true, to be skeptical of those in authority, then we are up for grabs for the next charlatan, political or religious, who comes ambling along. It is a thing that Jefferson laid great stress on. It wasn't enough he said to enshrine some rights in a constitution or bill of rights. The people had to be educated and they have to practice their skepticism and education. Otherwise we don't run the government. The government runs us.”

George_Sarton

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.”

Systematic Soldiering

“The greater part of the systematic soldiering, however, is done by the men with the deliberate object of keeping their employers ignorant of how fast work can be done. So universal is soldiering for this purpose, or under any of the ordinary systems of compensating labor, who does not devote a considerable part of his time to studying just how slowly he can work and still convince his employer that he is going at a good pace.”

Great Men Needed

“In the past the man has been first; in the future the system must be first. This in no sense, however, implies that great men are not needed.

Something Eternal

“Now there are some things we all know, but we don't take'm out and look at'm very often. We all know that something is eternal. And it ain't houses and it ain't names, and it ain't earth, and it ain't even the stars... everybody knows in their bones that something is eternal, and that something has to do with human beings. All the greatest people ever lived have been telling us that for five thousand years and yet you'd be surprised how people are always losing hold of it. There's something way down deep that's eternal about every human being.”
