The Structure of Scientific Revolutions is a book about the history of science by the philosopher Thomas S. Kuhn. Its publication was a landmark event in the history, philosophy, and sociology of scientific knowledge. Kuhn challenged the then prevailing view of progress in "normal science". The structure of scientific revolutions (PDF) (2nd, Enlarged ed.).

Those conceptions were ones I had previously drawn partly from scientific training itself and partly from a long-standing avocational interest in the philosophy of science. Somehow, whatever their pedagogic utility and their abstract plausibility, those notions did not at all fi the enterprise that historical study displayed. Yet they were and are fundamental to many discussions of science, and their failures of verisimilitude therefore seemed thoroughly worth pursuing.
The result was a drastic shift in my career plans, a shift from physics to history of science and then, gradually, from relatively straightforward historical problems back to the more philosophical concern that had initially led me to history. Kuhn further developed his ideas regarding incommensurability in the s and s.
In his unpublished manuscript The Plurality of Worlds , Kuhn introduces the theory of kind concepts: Kuhn introduced the concept of an exemplar in a postscript to the second edition of The Structure of Scientific Revolutions He noted that he was substituting the term 'exemplars' for 'paradigm', meaning the problems and solutions that students of a subject learn from the beginning of their education.
For example, physicists might have as exemplars the inclined plane , Kepler's laws of planetary motion , or instruments like the calorimeter. According to Kuhn, scientific practice alternates between periods of normal science and revolutionary science. During periods of normalcy, scientists tend to subscribe to a large body of interconnecting knowledge, methods, and assumptions which make up the reigning paradigm see paradigm shift.
Normal science presents a series of problems that are solved as scientists explore their field. The solutions to some of these problems become well known and are the exemplars of the field. Those who study a scientific discipline are expected to know its exemplars.
There is no fixed set of exemplars, but for a physicist today it would probably include the harmonic oscillator from mechanics and the hydrogen atom from quantum mechanics. The first edition of The Structure of Scientific Revolutions ended with a chapter titled "Progress through Revolutions", in which Kuhn spelled out his views on the nature of scientific progress. Since he considered problem solving to be a central element of science, Kuhn saw that for a new candidate paradigm to be accepted by a scientific community, "First, the new candidate must seem to resolve some outstanding and generally recognized problem that can be met in no other way.
Second, the new paradigm must promise to preserve a relatively large part of the concrete problem solving activity that has accrued to science through its predecessors.
While the new paradigm is rarely as expansive as the old paradigm in its initial stages, it must nevertheless have significant promise for future problem-solving. As a result, though new paradigms seldom or never possess all the capabilities of their predecessors, they usually preserve a great deal of the most concrete parts of past achievement and they always permit additional concrete problem-solutions besides.
In the second edition, Kuhn added a postscript in which he elaborated his ideas on the nature of scientific progress. He described a thought experiment involving an observer who has the opportunity to inspect an assortment of theories, each corresponding to a single stage in a succession of theories.
What if the observer is presented with these theories without any explicit indication of their chronological order? Kuhn anticipates that it will be possible to reconstruct their chronology on the basis of the theories' scope and content, because the more recent a theory is, the better it will be as an instrument for solving the kinds of puzzle that scientists aim to solve. Kuhn remarked: The Structure of Scientific Revolutions has been credited with producing the kind of "paradigm shift" Kuhn discussed.
The first extensive review of The Structure of Scientific Revolutions was authored by Dudley Shapere, a philosopher who interpreted Kuhn's work as a continuation of the anti- positivist sentiment of other philosophers of science, including Paul Feyerabend and Norwood Russell Hanson.
Solomon noted that Kuhn's views have often been suggested to have an affinity to those of Georg Wilhelm Friedrich Hegel. Barry Barnes detailed the connection between the sociology of scientific knowledge and Kuhn in his book T. Kuhn and Social Science. The Structure of Scientific Revolutions elicited a number of reactions from the broader sociological community. Following the book's publication, some sociologists expressed the belief that the field of sociology had not yet developed a unifying paradigm, and should therefore strive towards homogenization.
Others argued that the field was in the midst of normal science, and speculated that a new revolution would soon emerge. Some sociologists, including John Urry , doubted that Kuhn's theory, which addressed the development of natural science, was necessarily relevant to sociological development. Developments in the field of economics are often expressed and legitimized in Kuhnian terms. For a long while after the explosion of macroeconomics in the s, the field looked like a battlefield.
Over time however, largely because facts do not go away, a largely shared vision both of fluctuations and of methodology has emerged. Not everything is fine. Like all revolutions, this one has come with the destruction of some knowledge, and suffers from extremism and herding. In , The Structure of Scientific Revolutions was ranked as the second most frequently used book in political science courses focused on scope and methods. The changes that occur in politics , society and business are often expressed in Kuhnian terms, however poor their parallel with the practice of science may seem to scientists and historians of science.
The Structure of Scientific Revolutions was soon criticized by Kuhn's colleagues in the history and philosophy of science. In , a special symposium on the book was held at an International Colloquium on the Philosophy of Science that took place at Bedford College , London, and was chaired by Karl Popper.
The symposium led to the publication of the symposium's presentations plus other essays, most of them critical, which eventually appeared in an influential volume of essays. Kuhn expressed the opinion that his critics' readings of his book were so inconsistent with his own understanding of it that he was " A number of the included essays question the existence of normal science. In Toulmin's view, such revisions occur quite often during periods of what Kuhn would call "normal science.
In a series of texts published in the early s, Carl R. Kordig asserted a position somewhere between that of Kuhn and the older philosophy of science. His criticism of the Kuhnian position was that the incommensurability thesis was too radical, and that this made it impossible to explain the confrontation of scientific theories that actually occurs. According to Kordig, it is in fact possible to admit the existence of revolutions and paradigm shifts in science while still recognizing that theories belonging to different paradigms can be compared and confronted on the plane of observation.
Those who accept the incommensurability thesis do not do so because they admit the discontinuity of paradigms, but because they attribute a radical change in meanings to such shifts. Kordig maintains that there is a common observational plane. For example, when Kepler and Tycho Brahe are trying to explain the relative variation of the distance of the sun from the horizon at sunrise, both see the same thing the same configuration is focused on the retina of each individual.
This is just one example of the fact that "rival scientific theories share some observations, and therefore some meanings. At a secondary level, for Kordig there is a common plane of inter-paradigmatic standards or shared norms that permit the effective confrontation of rival theories. In , Hartry Field published an article that also sharply criticized Kuhn's idea of incommensurability. In particular, he took issue with this passage from Kuhn:. Newtonian mass is immutably conserved; that of Einstein is convertible into energy.
Only at very low relative velocities can the two masses be measured in the same way, and even then they must not be conceived as if they were the same thing. Kuhn Field takes this idea of incommensurability between the same terms in different theories one step further. Instead of attempting to identify a persistence of the reference of terms in different theories, Field's analysis emphasizes the indeterminacy of reference within individual theories.
Field takes the example of the term "mass", and asks what exactly "mass" means in modern post-relativistic physics. He finds that there are at least two different definitions:. Projecting this distinction backwards in time onto Newtonian dynamics, we can formulate the following two hypotheses:. According to Field, it is impossible to decide which of these two affirmations is true.
Prior to the theory of relativity, the term "mass" was referentially indeterminate. But this does not mean that the term "mass" did not have a different meaning than it now has. The problem is not one of meaning but of reference. The reference of such terms as mass is only partially determined: As a consequence, neither of the two terms fully denotes refers.
It follows that it is improper to maintain that a term has changed its reference during a scientific revolution ; it is more appropriate to describe terms such as "mass" as "having undergone a denotional refinement. In , Donald Davidson objected that the concept of incommensurable scientific paradigms competing with each other is logically inconsistent. But, Davidson argues, no coherent sense can be made of the idea of a conceptual scheme, and therefore no sense may be attached to the idea of an untranslatable language.
The close connection between the interpretationalist hypothesis and a holistic conception of beliefs is at the root of the notion of the dependence of perception on theory, a central concept in The Structure of Scientific Revolutions.
Kuhn maintained that the perception of the world depends on how the percipient conceives the world: According to this view, our interpretation of the world determines what we see. Jerry Fodor attempts to establish that this theoretical paradigm is fallacious and misleading by demonstrating the impenetrability of perception to the background knowledge of subjects. The strongest case can be based on evidence from experimental cognitive psychology, namely the persistence of perceptual illusions.
This impenetrability of the information elaborated by the mental modules limits the scope of interpretationalism. If the processes of elaboration of the mental modules are in fact independent of the background theories, then it is possible to maintain the realist view that two scientists who embrace two radically diverse theories see the world exactly in the same manner even if they interpret it differently. The point is that it is necessary to distinguish between observations and the perceptual fixation of beliefs.
While it is beyond doubt that the second process involves the holistic relationship between beliefs, the first is largely independent of the background beliefs of individuals. Other critics, such as Israel Scheffler , Hilary Putnam and Saul Kripke , have focused on the Fregean distinction between sense and reference in order to defend scientific realism.
Scheffler contends that Kuhn confuses the meanings of terms such as "mass" with their referents.
While their meanings may very well differ, their referents the objects or entities to which they correspond in the external world remain fixed.
