Lecture Notes on Paradigms and Paradigm Shifts in Geography

Introduction

• Speaker: Dr. Krishnanand
• Focus: Concept of paradigms and paradigm shifts in geography
• Importance of liking, subscribing, and sharing the channel

What is a Paradigm?

• Definition:
  • Origin: Latin/Greek, meaning "pattern" or "example"
  • Represents a common theme among theories or concepts.
• Philosophical Context:
  • Gained significance in the 20th century as a logical or conceptual structure within social sciences.

Historical Context of Paradigm in Geography

• Transition from descriptive geography to model-making in the 20th century.
• Evolution of geographical thought studied through:
  • Philosophical Viewpoints
  • Methodological Approaches
• Interaction between these viewpoints and methods is crucial to understanding paradigms.

Key Concepts

• Geographical Laws:
  • Tested under uncontrolled conditions, unlike physical laws.
  • Contextual in nature; influenced by time and space.
• Principle of Activity:
  • Every phenomenon in geography changes over time and space.

Thomas Kuhn's Contribution

• Kuhn's Work:
  • The Structure of Scientific Revolutions (1962) influenced discussions on paradigms.
  • Defined paradigm as a constellation of beliefs, values, techniques, and methods among a community.
• Phases of Paradigms:
  1. Pre-paradigm phase
  2. Professionalism
  3. Paradigm phase
  4. Crisis phase
  5. Paradigm phase two

Examples of Paradigm Shifts

• Historical shift from geocentric to heliocentric theories as a paradigm shift in astronomy.
• Use of examples from geography to illustrate paradigm shifts.

Other Scholars and Theories on Paradigms

• Peter Haggit (1983):
  • Defined paradigm as a "supermodel" providing rules for scientific investigation.
• Musterman (1970):
  • Identified three paradigms:
    1. Metaphysical Paradigms
    2. Sociological Paradigms
    3. Artifact or Construct Paradigms
• R.J. Johnston: Identified six geographical paradigms:
  1. Exploration
  2. Environmental Determinism
  3. Regionalism
  4. Spatial Science
  5. Behavioralism
  6. Radical and Structural Concepts

Exemplary Works in Geography

• Harvey and Hawley (1981): Identified five exemplary works that led to paradigm shifts:
  1. Ratzel's Anthropogeography (Environmental Determinism)
  2. Vidal de la Blache's Possibilism
  3. Sauer's Morphology of Landscape (Cultural Geography)
  4. Hartshorn's Nature of Geography (Regional Approach)
  5. Schaeffer's Exceptionalism (Nomothetic Approach)

Understanding Paradigm Shifts

• Cycle of Paradigms:
  • Growth, peak, degradation, and renewal cycle of paradigms.
• Major Paradigms in Geography:
  • Environmental Determinism
  • Possibilism
  • Regionalism
  • Spatial Analysis

Conclusion

• Paradigms in geography are essential to understanding the evolution of geographical thought.
• Continuous change and interaction between theories, beliefs, and methods shape the discipline.
