Douglas_Adams

Scientific Method

“The invention of the scientific method and science is, I'm sure we'll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and it rests on the premise that any idea is there to be attacked. If it withstands the attack then it lives to fight another day and if it doesn't withstand the attack then down it goes. Religion doesn't seem to work like that.”

Herbert_George_Andrewartha

Model Making

“Model-making, the imaginative and logical steps which precede the experiment, may be judged the most valuable part of the scientific method because skill and insight in these matters are rare. Without them, we do not know what experiment to do. But it is the experiment which provides the raw material for scientific theory. Scientific theory cannot be built directly from the conclusions of conceptual models.”

Scientific Method

“It is hard to describe the exact route to scientific achievement, but a good scientist doesn't get lost as he travels it.”

Science Uncertainty

“Science is uncertain. Theories are subject to revision; observations are open to a variety of interpretations, and scientists quarrel amongst themselves. This is disillusioning for those untrained in the scientific method, who thus turn to the rigid certainty of the Bible instead. There is something comfortable about a view that allows for no deviation and that spares you the painful necessity of having to think.”

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.”

Glory of Science

Validity of Hypothesis

“The functional validity of a working hypothesis is not a priori certain, because often it is initially based on intuition. However, logical deductions from such a hypothesis provide expectations (so-called prognoses) as to the circumstances under which certain phenomena will appear in nature. Such a postulate or working hypothesis can then be substantiated by additional observations ... The author calls such expectations and additional observations the prognosis-diagnosis method of research. Prognosis in science may be termed the prediction of the future finding of corroborative evidence of certain features or phenomena (diagnostic facts). This method of scientific research builds up and extends the relations between the subject and the object by means of a circuit of inductions and deductions.”

Claude_Bernard

Natural Man Arrogant

“Man is by nature metaphysical and proud. He has gone so far as to think that the idealistic creations of his mind, which correspond to his feelings, also represent reality. Hence it follows that the experimental method is by no means primitive or natural to man.”

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.”

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.”

Slow Progress

Good Hypothesis

“The Requisites of a good Hypothesis are:
: That It be Intelligible.
: That It neither Assume nor Suppose anything Impossible, unintelligible, or demonstrably False.
: That It be consistent with Itself.
: That It be lit and sufficient to Explicate the Phaenomena, especially the chief.
: That It be, at least, consistent, with the rest of the Phaenomena It particularly relates to, and do not contradict any other known Phaenomena of nature, or manifest Physical Truth.
 
The Qualities and Conditions of an Excellent Hypothesis are:
: That It be not Precarious, but have sufficient Grounds In the nature of the Thing Itself or at least be well recommended by some Auxiliary Proofs.
: That It be the Simplest of all the good ones we are able to frame, at least containing nothing that is superfluous or Impertinent.
: That It be the only Hypothesis that can Explicate the Phaenomena; or at least, that do's Explicate them so well.
: That it enable a skillful naturalist to foretell future Phaenomena by the Congruity or Incongruity to it; and especially the event of such experiments as are aptly devised to examine It, as Things that ought, or ought not, to be consequent to It.”

Scientific Method and Testing

“The scientific method is not part of their curriculum. The men and women who are called upon to test computer systems know little, if anything, about running a simple experiment.”

Requirements Testing

“Requirements testing is a subtle way of treating a nonlinear, unpredictable system as if it were a discrete symbol like a number or a word. The potential and the actual become muddled. Requirements are natural language statements, peppered in places with arithmetic. These are discrete and usually quite vague representations of the system as it might become. But the truth is that two teams writing requirements for the same system would describe them differently, and neither would get it quite right, simply because 'right' cannot be known until the system is built. ... Requirements testing is a little like trying to reduce crime in England by running a test for each line in the Magna Carta. In practice, rhetoric replaces the scientific method. As with mathematical proofs, the quest for 'true or not false' soon turns into a party - a not very cordial party - marked by endless debate over whether this sentence or that sentence has been verified by this moment of behavior or that.”

Hidden Links

"Finding hidden links between seemingly disparate phenomena is what makes the scientific method so powerful and compelling. The distinctive feature of science is that it is both broad and deep: broad in the way it tackles all physical phenomena and deep in the way it weaves them, economically, into a common explanatory scheme requiring fewer and fewer assumptions. No other system of thought can match its breadth and depth."

Scientific Inquiry

“That the great majority of those who leave school should have some idea of the kind of evidence required to substantiate given types of belief does not seem unreasonable.

Scientific Method

“The scientific method is the only authentic means at our command for getting at the significance of our everyday experiences of the world in which we live. It means that scientific method provides a working pattern of the way in which and the conditions under which experiences are used to lead ever onward and outward. ... Consequently, whatever the level of experience, we have no choice but either to operate in accord with the pattern it provides or else to neglect the place of intelligence in the development and control of a living and moving experience.”

Galen

Seeks the Truth

“It would be better, I think, for the man who really seeks the truth not to ask what the poets say; rather, he should first learn the method of finding the scientific premises that I discussed in the second book; then he should train and exercise himself in this method; and when his training is sufficiently advanced, then, as he approaches each particular problem, he should enquire into the premise needed for proving it, which premise he should take from simple sense-perception, which from experience, whether drawn from life or from the arts, which from the truths clearly apprehended by the mind, in order to draw out from them the desired conclusion.”

John_Gribbin

Scientific Method

“The Big Idea that had been developed in the seventeenth century ... is now known as the scientific method. It says that the way to proceed when investigating how the world works is to first carry out experiments and/or make observations of the natural world. Then, develop hypotheses to explain these observations, and (crucially) use the hypothesis to make predictions about the future outcome of future experiments and/or observations. After comparing the results of those new observations with the predictions of the hypotheses, discard those hypotheses which make false predictions, and retain (at least, for the time being) any hypothesis that makes accurate predictions, elevating it to the status of a theory. Note that a theory can never be proved right. The best that can be said is that it has passed all the tests applied so far.”

Robert_Heinlein

Scientific Method

“There are but two ways of forming an opinion in science. One is the scientific method; the other, the scholastic. One can judge from experiment, or one can blindly accept authority.

To the academic mind, authority is everything and facts are junked when they do not fit theory laid down by authority.”.

Fred_Hoyle

Scientific Hypotheses

“It is often held that scientific hypotheses are constructed, and are to be constructed, only after a detailed weighing of all possible evidence bearing on the matter, and that then and only then may one consider, and still only tentatively, any hypotheses. This traditional view however, is largely incorrect, for not only is it absurdly impossible of application, but it is contradicted by the history of the development of any scientific theory. What happens in practice is that by intuitive insight, or other inexplicable inspiration, the theorist decides that certain features seem to him more important than others and capable of explanation by certain hypotheses. Then basing his study on these hypotheses the attempt is made to deduce their consequences. The successful pioneer of theoretical science is he whose intuitions yield hypotheses on which satisfactory theories can be built, and conversely for the unsuccessful (as judged from a purely scientific standpoint).”

Robert_Lawrence_Kuhn

Scientific Method

“I like to distinguish between the scientific method, which is applied to all materialistic theories. The scientific method is one of observation or experimentation, repeatability, falsification, the repeatability by different techniques of different labs, or prediction and results. It's a scientific method. I say that if it's a non-physical theory, or the theory has any aspect of non-physicalism to it, it doesn't have to be all, any aspect invalidates, to some degree invalidates, the scientific method as I just described from being applicable. And I think there's a tendency in some theories that have some non-physical aspect to try to show their legitimacy by applying the scientific method... I think that's a false desire, because once you're non-physical you are invalidating, to one degree or another, the scientific method. Maybe not totally, but in some degree.”

Scientific Method Limits

“Every theory that is dualist, panpsychist or idealist agrees that we can study the biological facets of consciousness by studying the brain – but they all claim this will never lead to a complete understanding. In other words, there are limits to how far the scientific method can take us.”

Materialist Science

“In materialist science, only that is true that you can objectify, what you can measure, what you can duplicate, or what you can falsify. Then it is true. Now what you feel and what you think, your consciousness, you cannot objectify, you cannot duplicate, you cannot measure, and you cannot falsify. Consciousness, the essence of who you are, what you feel, what you think, is beyond our current materialist science. So, they call it an illusion. But it is the essence of who we are. We have to expand science into post-materialist science. We have to change the paradigm to include subjective experiences... Science should include subjective experiences into the scientific method... The materialist aspect of science is still important, but it's not enough... This is a totally different approach when you realize that everything has its subjective aspects.”

Karl_Popper

Epistemology

“In accordance with my proposal made above, epistemology, or the logic of scientific discovery, should be identified with the theory of scientific method. The theory of method, in so far as it goes beyond the purely logical analysis of the relations between scientific statements, is concerned with the choice of methods — with decisions about the way in which scientific statements are to be dealt with. These decisions will of course depend in their turn upon the aim which we choose from among a number of possible aims. The decision here proposed for laying down suitable rules for what I call the ‘empirical method’ is closely connected with my criterion of demarcation: I propose to adopt such rules as will ensure the testability of scientific statements; which is to say, their falsifiability.”

Hans_Reichenbach

Picture of Scientific Method

“The picture of scientific method drafted by modern philosophy is very different from traditional conceptions. Gone is the ideal of a universe whose course follows strict rules, a predetermined cosmos that unwinds itself like an unwinding clock. Gone is the ideal of the scientist who knows the absolute truth. The happenings of nature are like rolling dice rather than like revolving stars; they are controlled by probability laws, not by causality, and the scientist resembles a gambler more than a prophet. He can tell you only his best posits — he never knows beforehand whether they will come true. He is a better gambler, though, than the man at the green table, because his statistical methods are superior. And his goal is staked higher — the goal of foretelling the rolling dice of the cosmos. If he is asked why he follows his methods, with what title he makes his predictions, he cannot answer that he has an irrefutable knowledge of the future; he can only lay his best bets. But he can prove that they are best bets, that making them is the best he can do — and if a man does his best, what else can you ask of him?”

Empirical Approach

“Science needs to be liberated from these constrictive dogmas of mechanistic materialism... If we go beyond those dogmas, science gets much more interesting. All sorts of new research become possible. New questions can be asked. We can find out more about nature and more about consciousness by doing science in a new more open way. But what remains part of science so crucial to it is the empirical approach. The putting forward of hypotheses, the critical discussion, and the testing of hypotheses by experiment, the scientific method.”

Scientific Method Complicated and Simple

“Scientific method, although in its more refined forms it may seem complicated, is in essence remarkably simply. It consists in observing such facts as will enable the observer to discover general laws governing facts of the kind in question. The two stages, first of observation, and second of inference to a law, are both essential, and each is susceptible of almost indefinite refinement.”

Carl_Sagan

Wrong Hypothesis OK

“There are many hypotheses in science which are wrong. That's perfectly all right; they're the aperture to finding out what's right. Science is a self-correcting process. To be accepted, new ideas must survive the most rigorous standards of evidence and scrutiny.”
  • Source: Carl Sagan, Quoted in Donald R. Prothero and Carl Dennis Buell, Evolution: What the Fossils Say and Why it Matters (2007), 3.

Science Is Not Perfect

“[Science] is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. ... The obvious is sometimes false; the unexpected is sometimes true.”

True Conclusions

“But although in theory physicists realize that their conclusions are ...not certainly true, this ... does not really sink into their consciousness. Nearly all the time ...they ... act as if Science were indisputably True, and what's more, as if only science were true ...Any information obtained otherwise than by the scientific method, although it may be true, the scientists will call 'unscientific,' using this word as a smear word, by bringing in the connotation from its original [Greek] meaning, to imply that the information is false, or at any rate slightly phony.”

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.”

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.”

Progress of Science

“The progress of science is often affected more by the frailties of humans and their institutions than by the limitations of scientific measuring devices. The scientific method is only as effective as the humans using it. It does not automatically lead to progress.”
