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.
Reading Notes

An anomaly is not so much discovered as admitted: a framework can only see a crisis where it has first declared that this should not happen.
The key move in this book is to redescribe discovery as something framework-dependent: a paradigm is not merely a theory about the world but a set of commitments about which questions are worth asking, which answers count as admissible, and which observations count as data. What it genuinely changes is the meaning of an anomaly — the same observation is a puzzle awaiting solution while the framework holds, and becomes a crisis only once the framework itself begins to loosen; the difference lies not in the observation but in how much slack the framework still has. The easily missed point is that Kuhn does not present paradigm change as a cumulative victory of evidence. He states plainly that the choice between paradigms cannot be fully determined by logic and evidence and rests in the end on the assent of the relevant community, which is precisely why textbooks rewrite revolutions as a smooth sequence of discoveries. The caution worth keeping is that the argument is easily abused to shelve any unwelcome piece of evidence by calling it "a matter of paradigms," whereas Kuhn's intention runs the other way — a framework must answer the tests it has declared for itself, or it will not even be able to recognise its own anomalies.
