“Normal science, the activity in which most scientists inevitably spend almost all their time, is predicated on the assumption that the scientific community knows what the world is like”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“And even when the apparatus exists, novelty ordinarily emerges only for the man who, knowing with precision what he should expect, is able to recognize that something has gone wrong.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Under normal conditions the research scientist is not an innovator but a solver of puzzles, and the puzzles upon which he concentrates are just those which he believes can be both stated and solved within the existing scientific tradition.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Truth emerges more readily from error than from confusion.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Perhaps science does not develop by the accumulation of individual discoveries and inventions”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“If these out-of date beliefs are to be called myths, then myths can be produced by the same sorts of methods and held for the same sorts of reasons that now lead to scientific knowledge”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“The man who is striving to solve a problem defined by existing knowledge and technique is not, however, just looking around. He knows what he wants to achieve, and he designs his instruments and directs his thoughts accordingly. Unanticipated novelty, the new discovery, can emerge only to the extent that his anticipations about nature and his instruments prove wrong. . . . There is no other effective way in which discoveries might be generated.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Almost always the men who achieve these fundamental inventions of a new paradigm have been either very young or very new to the field whose paradigm they change.15 And perhaps that point need not have been made explicit, for obviously these are the men who, being little committed by prior practice to the traditional rules of normal science, are particularly likely to see that those rules no longer define a playable game and to conceive another set that can replace them.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Observation and experience can and must drastically restrict the range of admissible scientific belief, else there would be no science. But they cannot alone determine a particular body of such belief. An apparently arbitrary element, compounded of personal and historical accident, is always a formative ingredient of the beliefs espoused by a given scientific community at a given time”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Unanticipated novelty, the new discovery, can emerge only to the extent that his anticipations about nature and his instruments prove wrong.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Newton's three laws of motion are less a product of novel experiments than of the attempt to reinterpret well-known observations in terms of motions and interactions of primary neutral corpuscles”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Gravity, interpreted as an innate attraction between every pair of particles of matter, was an occult quality in the same sense as the scholastics' "tendency to fall" had been”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Its assimilation requires the reconstruction of prior theory and re-evaluation of prior fact, an intrinsically revolutionary process that is seldom completed a single man and never overnight”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“What man sees depends both upon what he looks at and also upon what his previous visual-conception experience has taught him to see.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“To reject one paradigm without simultaneously substituting another is to reject science itself.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Unable either to practice science without the Principia or to make that work conform to the corpuscular standards of the seventeenth century, scientists gradually accepted the view that gravity was indeed innate”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“No language thus restricted to reporting a world fully known in advance can produce mere neutral and objective reports on "the given." Philosophical investigation has not yet provided even a hint of what a language able to do that would be like.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Max Planck, surveying his own career in his Scientific Autobiography, sadly remarked that “a new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“though the world does not change with a change of paradigm, the scientist afterward works in a different world. Nevertheless,”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“once it has achieved the status of paradigm, a scientific theory is declared invalid only if an alternate candidate is available to take its place.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“The man who succeeds proves himself an expert puzzle-solver, and the challenge of the puzzle is an important part of what usually drives him on.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“Because scientists are reasonable men, one or another argument will ultimately persuade many of them. But there is no single argument that can or should persuade them all. Rather than a single group conversion, what occurs is an increasing shift in the distribution of professional allegiances.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“For reasons that are both obvious and highly functional, science textbooks (and too many of the older histories of science) refer only to that part of the work of past scientists that can easily be viewed as contributions to the statement and solution of the texts' paradigm problems. Partly by selection and partly by distortion, the scientists of early ages are implicitly represented as having worked upon the same set of fixed problems and in accordance with the same set of fixed canons that the most recent revolution in scientific theory and method has made seem scientific.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“very existence of science depends upon vesting the power to choose between paradigms in the members of a special kind of community.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“The depreciation of historical fact is deeply, and probably functionally, ingrained in the ideology of the scientific profession, the same profession that places the highest of all values upon factual details of other sorts.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“progress in science is not a simple line leading to the truth. It is more progress away from less adequate conceptions of, and interactions with, the world (§XIII). Let”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“The question I hoped to answer,was how much mechanics Aristotle had known, how much he had left for people such as Galileo and Newton to discover. Given that formulation, I rapidly discovered that Aristotle had known almost no mechanics at all... that conclusion was standard and it might in principle have been right. But I found it bothersome because, as I was reading him, Aristotle appeared not only ignorant of mechanics, but a dreadfully bad physical scientist as well. About motion, in particular, his writings seemed to me full of egregious errors, both of logic and of observation.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“In science, as in the playing card experiment, novelty emerges only with difficulty, manifested by resistance, against a background provided by expectation.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“When it repudiates a past paradigm, a scientific community simultaneously renounces, as a fit subject for professional scrutiny, most of the books and articles in which that paradigm had been embodied. Scientific education makes use of no equivalent for the art museum or the library of classics, and the result is a sometimes drastic distortion in the scientist's perception of his discipline's past. More than the practitioners of other creative fields, he comes to see it as leading in a straight line to the discipline's present vantage. In short, he comes to see it as progress. No alternative is available to him while he remains in the field.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions
“....the power of a science seems quite generally to increase with the number of symbolic generalizations its practitioners have at their disposal.”
― Thomas S. Kuhn, quote from The Structure of Scientific Revolutions

Little, BigBookQuoters is a community of passionate readers who enjoy sharing the most meaningful, memorable and interesting quotes from great books. As the world communicates more and more via texts, memes and sound bytes, short but profound quotes from books have become more relevant and important. For some of us a quote becomes a mantra, a goal or a philosophy by which we live. For all of us, quotes are a great way to remember a book and to carry with us the author’s best ideas.
We thoughtfully gather quotes from our favorite books, both classic and current, and choose the ones that are most thought-provoking. Each quote represents a book that is interesting, well written and has potential to enhance the reader’s life. We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.
Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
