Kuhn’s Paradigms


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.

Concepts and Terminologies

Concept / Term Simple Meaning
Paradigm A commonly accepted framework/model that guides scientific research
Exemplar A successful concrete problem-solution used as a model for future research
Disciplinary Matrix Shared beliefs, values, concepts, methods and techniques of a scientific community
Preparadigm Period Stage when several competing schools of thought exist
Multi-paradigmatic Period Period in which different schools have their own research models
Scientific Maturity / Professionalization Stage when a discipline develops an established identity and research framework
Normal Science Research conducted within an accepted paradigm
Puzzle-solving Solving research problems according to the expectations of the existing paradigm
Crisis Stage when the existing paradigm cannot adequately solve accumulating problems
Scientific Revolution Major transformation in which a new paradigm replaces the old one
Paradigm Shift Change from one dominant scientific framework to another
Historical Continuity Idea that scientific development should maintain links with previous knowledge
Research Community Scientists/researchers sharing a common scientific framework
Scientific Tradition An established way of understanding and investigating scientific problems
Theoretical Framework Concepts and assumptions used to explain phenomena
Methodological Debate Discussion about appropriate methods of scientific investigation
Subjectivity Influence of human choice, values or judgement in selecting paradigms
Value Judgement Evaluation influenced by particular beliefs or values
Episteme Foucault's term for a historically specific structure/worldview of knowledge
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:

  1. End with continued acceptance of the old paradigm, or

  2. 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.

 Contributions

Scholar Contribution / Idea Year mentioned
Thomas S. Kuhn Paradigm, normal science, crisis and scientific revolution 1962; 1970
Alfred Hettner Scientific development is not always linear; emphasized historical continuity 1930
Peter Haggett Described paradigm as a "supermodel" guiding phenomena and methods 1983
Mair Clarified Kuhn's two meanings of paradigm: exemplar and disciplinary matrix 1986
Vidal de la Blache Regional monographs as examples/exemplars of geographical research
Peter Taylor Younger researchers may have an interest in challenging established scientific ideology 1976
David Bird Connected paradigm with dogma/orthodoxy and criticized Kuhnian thinking 1977
Karl Popper Criticized normal science; advocated continuous criticism and permanent revolution 1970
Paul Feyerabend Rejected strict alternation between normal science and revolution; emphasized theoretical pluralism
Michel Foucault Connected power, knowledge and truth; introduced concept of episteme 1972; 1980

The source specifically identifies Kuhn, Hettner, Haggett, Mair, Taylor, Bird, Popper, Feyerabend and Foucault in its discussion of scientific development.

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 → Revolution

  • Argued 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.

Regional Geography, Systematic Geography, Idiographic, Nomothetic, Inductive and Deductive Approaches

T wo major ways of studying Geography : the Regional Approach and the Systematic Approach . It also explains the related ideas of idiographic vs. nomothetic and inductive vs. deductive reasoning , especially in the context of the Hartshorne–Schaefer debate . 1. Regional Geography: “All About One” Regional Geography studies one particular region in detail . A region is an area that has some degree of homogeneity (sameness) within its boundary but is also unique or different from other regions . For example, if we study Palakkad District , we may study: Relief and drainage Climate Soil Vegetation Agriculture Population Occupation Economy Culture Political characteristics The purpose is to understand the complete geographical personality of Palakkad and the relationships among its different features. Key concepts Region: A geographical area with identifiable characteristics and boundaries. Homogeneity: Si...

Models and Theories in Geography

Geographical Models A model is a simplified representation of reality used to describe, explain, simulate, and predict geographical phenomena. Types Physical (Iconic) Models – Three-dimensional representations (e.g., globe, relief model). Conceptual Models – Diagrams or frameworks explaining geographical relationships. Mathematical (Quantitative) Models – Equations and statistical models for spatial analysis and prediction. Simulation Models – Computer-based models that simulate geographical processes (e.g., climate, flood, urban growth). Major Geographical Models Model Scholar Year Concept Johann Heinrich von Thünen Agricultural Land Use Model 1826 Land use varies with distance from the market. Walter Christaller Central Place Model 1933 Distribution of settlements and services. Ernest Burgess Concentric Zone M...

Multispectral and Hyperspectral Imaging Systems

The main idea is how a remote-sensing sensor collects information about an area . A sensor does not simply take an ordinary photograph. It measures the electromagnetic energy reflected or emitted by objects in different wavelength bands . Depending on how many bands are measured and how the sensor collects them, different imaging systems are used. 1. Multispectral vs. Hyperspectral Multispectral imaging (MSI) records information in a limited number of relatively broad, separate spectral bands , such as blue, green, red, near-infrared and shortwave infrared. Hyperspectral imaging (HSI) records information in many narrow and usually contiguous spectral bands . Therefore, it provides a much more detailed spectral signature of each pixel. The resulting dataset is commonly called a hyperspectral data cube (hypercube) because it contains: X-axis → spatial information Y-axis → spatial information Z-axis → wavelength/spectral information Thus, hype...

Kuhn’s model in Geography

Thomas Kuhn (1922–1996) Thomas Samuel Kuhn was an American philosopher and historian of science . In 1962 , he published The Structure of Scientific Revolutions , introducing the concepts of paradigm and paradigm shift , which transformed the understanding of scientific progress. Definition: A framework of assumptions, concepts, and values that guide a group or field. Example (Science): Moving from a-earth-centered universe to a sun-centered solar system is a change in the scientific paradigm. Example (Daily Life): A shared cultural belief or a standard way of doing business.   Kuhn's Model (1962) Kuhn's Model explains that science develops through successive paradigms rather than by continuous, gradual progress. Stages of Kuhn's Model Pre-paradigm Stage – No common theory; different ideas exist. Normal Science – Scientists work within an accepted paradigm . Crisis – Anom...
