Thomas Kuhn
Thomas Kuhn was an American philosopher and historian of science whose The Structure of Scientific Revolutions (1962) fundamentally changed the understanding of how science develops. His concepts of paradigms, normal science, and scientific revolutions — the idea that science does not progress by steady accumulation but through revolutionary shifts in basic assumptions — transformed the philosophy of science and entered common vocabulary.
Key Ideas
Key Contributions
- ● Introduced the concept of paradigms — shared frameworks of assumptions, methods, and problems that define a scientific discipline
- ● Distinguished between normal science (puzzle-solving within a paradigm) and revolutionary science (paradigm shifts)
- ● Argued that scientific revolutions involve incommensurable paradigm shifts — rival paradigms cannot be fully compared using a neutral framework
- ● Challenged the positivist view of science as cumulative progress, proposing instead a model of discontinuous revolutionary change
Core Questions
Key Claims
- ✓ Normal science operates within a paradigm — a shared framework of theories, methods, and problems that scientists take for granted
- ✓ Scientific revolutions occur when anomalies accumulate to the point where the existing paradigm can no longer accommodate them
- ✓ Rival paradigms are incommensurable — scientists working in different paradigms literally see the world differently
- ✓ Science does not progress by accumulation toward truth but through revolutionary paradigm shifts that restructure the field
Biography
Life

The Structure of Scientific Revolutions (1962) became one of the most cited academic books of the 20th century. He taught at Berkeley, Princeton, and MIT. He died on June 17, 1996.
Legacy
Kuhn's concept of paradigm shifts has influenced not only the philosophy of science but also sociology, economics, and cultural discourse.
