This inquiry concerns the geographical school of thought that incorporates Marxian theory. Marxian theory, defined by its examination of social, economic, and political frameworks and its emphasis on class struggle as a driver of societal transformation, is primarily associated with the Radical school of thought among the given alternatives. This school's focus on inequality, power dynamics, and social justice resonates strongly with Marxian principles. Let's analyze the provided options:
- Humanistic: This approach prioritizes human values and subjective experiences, often in opposition to empirical or quantitative methodologies. It is not a primary user of Marxian theory.
- Behavioural: This school investigates geographical phenomena through behavioral patterns, employing quantitative techniques and models rather than Marxian theory.
- Radical: By applying Marxian theory to deconstruct societal structures and inequalities, this school emerges as the accurate selection.
- Post-modernism: While it critiques established theories and methods, post-modernism does not specifically adopt Marxian theory.
Therefore, the Radical school of thought is identified as the one that utilizes Marxian theory.
