The Structure of Scientific Revolutions

What is this book about?

Kuhn argues that science does not accumulate linearly but cycles between “normal science” and revolution: a paradigm guides research until accumulated anomalies can no longer be explained, at which point the paradigm shifts. The framework rewrites the history of science as a sociological problem rather than a heroic one.

Why read it?

The vocabulary of paradigm, incommensurability, and normal science has become common currency, but the original meanings are far stricter than everyday usage. Reading the source tells you what these concepts promise and what they sidestep.

Core Ideas

• For most of its life, science is puzzle-solving normal activity, not continuous revolution.
• A paradigm shift is not simply the victory of new evidence; it involves persuasion at social and psychological levels.
• Different paradigms may be impossible to compare by shared standards — a condition he calls incommensurability.
• Scientific progress is not approach to a single truth but improvement in problem-solving power.

What questions does this book try to answer?

• How does scientific knowledge grow — by accumulation or by rupture?
• When an old paradigm cannot explain new evidence, how does the scientific community choose?

Who should read it?

For readers interested in the philosophy of science and the sociology of knowledge. It is conceptually dense; secondary literature helps.
