Thomas Kuhn
Paradigm shifts — scientific knowledge as a tradition-constituted social practice punctuated by revolutionary reorganizations
"The Structure of Scientific Revolutions" (1962, in the International Encyclopedia of Unified Science) reframed the history and philosophy of science: scientific knowledge progresses not by linear accumulation but through long periods of "normal science" (puzzle-solving within an accepted paradigm) punctuated by revolutionary paradigm shifts (Copernicus, Newton, Lavoisier, Darwin, Einstein) that change the categories themselves. The book's central concepts — paradigm, incommensurability, normal science, anomaly, crisis, revolution — became unavoidable across the human and social sciences. Kuhn spent his career trying to clarify and qualify Structure's claims, sometimes against the relativist readings (Feyerabend, the sociologists of scientific knowledge) that took his work further than he was willing to go.

Kuhn is the principal twentieth-century philosophical source for the social-constructionist view that scientific categories are shaped by paradigms which are themselves community-constituted.
"Communities do not work on individual problems; they work on problems that have been defined by the paradigm." (Structure, ch. 4)
Although Kuhn resisted the label, Structure of Scientific Revolutions was one of the principal sources for the late-twentieth-century postmodern destabilization of foundationalist accounts of knowledge.
"The proponents of competing paradigms practice their trades in different worlds." (Structure, ch. 10)
Kuhn's account of science as tradition-constituted problem-solving has strong pragmatist resonances; the late Kuhn explicitly engaged with Quine and pragmatist epistemology.
"Once a first paradigm has been achieved, there can be no scientific research in the absence of a paradigm." (Structure, ch. 2)
The mature Kuhn (Road Since Structure) defended a position more realist than the original Structure had implied: there is a real natural world to which scientific paradigms more or less successfully respond.
"What is unaltered by a scientific revolution is the world: nature itself is just exactly the same after the revolution as before." (Road Since Structure)
Kuhn's book was the principal vehicle for the historicist demolition of the logical positivist program of science as the accumulation of confirmed observation-statements.
"Logical positivism, having dominated philosophy of science for thirty years, fell to historicist criticism in the decade after Structure." (paraphrasing the consensus reception)
Internal Tensions
Kuhn spent thirty years trying to defend Structure against the radical-relativist readings (Feyerabend, the Edinburgh Strong Programme, much of science-studies after 1970). His later "second thoughts" attempted to clarify paradigm into "exemplar" and "disciplinary matrix" and to defend a realist core. The book's influence outran the author's preferred reading.
I. Time
Historical time of scientific tradition; revolutions reorganize the categorial structure without making the underlying world change.
Attributes

Standard substantival matter as the world that paradigms try to track.
Attributes
IV. Observer
Plural scientific communities. Mediated knowledge through paradigms. No metaphysical agency.

VI. Information
Information about the world conserved; scientific paradigms partially capture and partially distort.
