Overview
Thomas Kuhn introduced the concept of "paradigm shifts," showing that science advances through revolutionary overthrows of established frameworks.
Kuhn, a historian and philosopher of science at MIT, published The Structure of Scientific Revolutions in 1962. The book introduced 'paradigm shift' into the language and argued that science progresses not linearly but through revolutionary breaks between incommensurable frameworks. The book has been wildly influential far beyond philosophy of science — into sociology, cultural studies, and business writing, often in oversimplified forms.
Key Ideas
Normal science solves puzzles
Most scientific work consists of solving problems within an accepted paradigm.
Anomalies trigger crises
When enough observations cannot be explained, a crisis opens the door to revolution.
Paradigms are incommensurable
Scientists under different paradigms literally see the world differently.
Who should read this
Readers serious about understanding how scientific knowledge actually progresses, as opposed to the idealised textbook version. Also useful for anyone who has encountered 'paradigm shift' used loosely in business and wants to know what Kuhn actually meant. The book rewards careful, slow reading.
Who might skip it
Skip if you want a quick read — Structure is short but dense, and Kuhn's argument is more carefully qualified than his popularisers acknowledge. Skip also if you are deeply committed to a naive view of scientific progress; Kuhn's argument is a challenge to that view, not a decoration.
The verdict
One of the most important books in twentieth-century philosophy of science, and a case study in how ideas get distorted as they spread. The actual argument is both more interesting and more tentative than 'science has revolutions'. Worth reading the original rather than relying on the popular summaries.
"The successive transition from one paradigm to another via revolution is the usual developmental pattern of mature science."
— Thomas Kuhn, The Structure of Scientific Revolutions
