Thomas S. Kuhn – Author Biography
Early Life
Thomas Samuel Kuhn was born on 18 July 1922 in Cincinnati, Ohio. He studied physics at Harvard University, earning his bachelor’s, master’s, and PhD there — training as a scientist before he became a philosopher of science.
Career
Kuhn taught at Berkeley, Princeton, and MIT, but his reputation rests overwhelmingly on a single book: The Structure of Scientific Revolutions (1962). In it he argued that science advances not by steady accumulation but through “paradigm shifts” — periods of normal science punctuated by revolutions that rewrite the rules, as when Copernican astronomy replaced the Ptolemaic system. The book’s concepts of paradigms, normal science, and incommensurability transformed the philosophy and history of science. He spent his later career elaborating and defending these ideas, dying in 1996.
Major Works
The Structure of Scientific Revolutions (1962) is his landmark work, alongside The Copernican Revolution (1957) and Black-Body Theory and the Quantum Discontinuity (1978).
Writing Style and Themes
Kuhn wrote dense but rewarding academic prose, building arguments through detailed historical case studies. His central themes are that scientific truth is historically situated, that observation is theory-laden, and that revolutions in thought require conversion as much as evidence. “Paradigm shift” became one of the most borrowed phrases in the English language.
Legacy
Few academic books have travelled as far: The Structure of Scientific Revolutions reshaped not only philosophy of science but business, politics, and popular culture. Kuhn made the history of science a central discipline and gave every field a vocabulary for describing its own revolutions.
