The given content explains Thomas S. Kuhn’s model of scientific development, its application to geography, and criticisms by Karl Popper, Paul Feyerabend, Michel Foucault, and others.
1. Basic Idea
Kuhn argued that science does not develop continuously in a straight line. Instead, scientific development occurs through:
Preparadigm → Paradigm → Normal Science → Crisis → Scientific Revolution → New Paradigm
A new paradigm may replace an older one, producing a major change in the way scientists understand and study a subject.

| Regime of Truth | Foucault's idea that societies determine which forms of knowledge are accepted as "truth" |
| Power–Knowledge | Foucault's concept that power and knowledge are closely interconnected |
| Permanent Revolution | Popper's idea that science should remain continuously critical and revolutionary |
| Myth of the Framework | Popper's criticism of unquestioned dependence on established theoretical frameworks |
Kuhn’s Model of Scientific Development
Stage 1: Preparadigm Period
Several competing schools of thought exist.
There is no universally accepted framework.
Different scientists propose different explanations.
Can also be called a multi-paradigmatic stage when paradigms are understood as exemplars.
Stage 2: Professionalization / Scientific Maturity
A discipline develops a clearer identity.
Its subject matter, concepts and methods become more clearly defined.
In geography, the development of university-level geographical education contributed to defining the discipline's domain.
Stage 3: Paradigm Formation
One school gradually becomes dominant.
Its framework gains academic acceptance.
It provides the problems, questions and methods considered appropriate.
Stage 4: Normal Science
Researchers work within the accepted paradigm.
Research focuses on solving specific problems.
Kuhn calls this "puzzle-solving."
The paradigm directs what researchers observe and what questions they ask.
It provides efficiency because researchers do not have to repeatedly justify the basic philosophical foundations of their research.
Stage 5: Crisis
A crisis develops when:
Increasing numbers of problems cannot be solved.
Existing explanations become inadequate.
Old data are reassessed.
New theories and alternative explanations emerge.
Philosophical and methodological debates increase.
The crisis can either:
End with continued acceptance of the old paradigm, or
Lead to the emergence of a new paradigm.
Stage 6: Scientific Revolution
A new paradigm gains support.
The old disciplinary framework is challenged.
The theoretical structure of the field is reconstructed.
Research may move in a completely new direction.
Younger researchers often become important supporters of the new paradigm.
Stage 7: New Paradigm
The new paradigm becomes dominant and a new period of normal science begins.

Two Meanings of "Paradigm" in Kuhn
Kuhn later clarified that "paradigm" had two closely related meanings.
A. Exemplar
A specific successful example of solving a scientific problem.
Example in Geography:
Regional monographs associated with Vidal de la Blache and his contemporaries served as models for geographical research.
B. Disciplinary Matrix
The broader system shared by a scientific community:
Beliefs + Values + Concepts + Methods + Techniques + Assumptions
This is the meaning most commonly applied to geography.

Criticisms
Karl Popper
Science should not remain in normal science for long periods.
Scientists should continuously question established theories.
Favoured a permanent revolution in science.
Criticized unquestioned acceptance of scientific "dogmas."
Key term: Permanent Revolution
Paul Feyerabend
Rejected Kuhn's simple sequence of:
Normal Science → Crisis → RevolutionArgued that alternative theories can exist simultaneously.
Supported theoretical pluralism.
Michel Foucault
Foucault approached scientific history differently.
Key concepts:
Power
Knowledge
Truth
Regime of Truth
Episteme
According to Foucault, accepted knowledge is influenced by the power relations of society. Changes in society's underlying systems of thought (epistemes) can therefore change scientific knowledge.
7. Timeline
1930 – Alfred Hettner
Scientific development may zig-zag rather than follow a straight line; emphasized historical continuity.
1962 – Thomas Kuhn
Published The Structure of Scientific Revolutions and developed the concept of paradigm, normal science, crisis, and scientific revolution.
1970 – Kuhn
Second edition clarified the concept of paradigm, particularly exemplar and disciplinary matrix.
1970 – Karl Popper
Criticized excessive dependence on normal science and advocated continuous critical scientific activity.
1970s – Paradigm Debate
The Kuhnian model generated considerable debate concerning objectivity, subjectivity, scientific traditions and value judgements.
1976 – Peter Taylor
Highlighted the potential role of younger researchers in challenging established scientific ideologies.
1977 – David Bird
Criticized the tendency to treat paradigms as dogmas or systems of orthodoxy.
1972 & 1980 – Michel Foucault
Developed the concepts of episteme, power–knowledge and regime of truth.
1983 – Peter Haggett
Described paradigm as a "supermodel" that guides geographical investigation.
1986 – Mair
Clarified the distinction between exemplar and disciplinary matrix.
Kuhn's central argument:
Science develops through paradigms, not simply through continuous accumulation of knowledge.
Main sequence:
Preparadigm → Paradigm → Normal Science → Crisis → Revolution → New Paradigm
Paradigm =
Exemplar → successful model/problem solution
Disciplinary Matrix → shared beliefs, values, methods and techniques
Normal Science = puzzle-solving within an accepted paradigm.
Crisis = existing paradigm cannot solve increasing problems.
Revolution = fundamental replacement/reconstruction of the scientific framework.
Popper = permanent revolution and continuous criticism.
Feyerabend = theoretical pluralism; rejected a rigid Kuhnian sequence.
Foucault = power + knowledge + truth + episteme.
Hettner = historical continuity and non-linear development.
Geographical significance: Kuhn's model helps explain how geography moved through competing schools and changing dominant approaches rather than developing as a completely continuous, linear discipline.
