Pieter Saey – The social action field

An epistemological and geographical evaluation of Wallerstein’s world-systems analysis

The social action field is a forthcoming book, the magnum opus of geographer Prof. Em. Pieter Saey. Bringing together decades of work on geography, spatial theory, and world-systems analysis, it offers a major re-evaluation of Wallerstein’s framework and its implications for social change.

About the book

There’s plenty of reason to be angry with capitalism. But what can you do about it? With that question in mind, Pieter Saey examines one of the approaches that envisions the end of capitalism: Wallerstein and Hopkins’ world-systems analysis. What has it got to say about the social action field? To this end, he examines how this analysis establishes the relationship between economic-geographic and political-geographic structures. The focus is on the connection between the macro-geographic division of labor across core, semi-peripheral, and peripheral zones and the global distribution of internally strong and weak states—in other words, on the question of how, in the modern world-system, economy structurally conditions the (un)democratic nature of states. The answer required a great deal of scientific-theoretical weeding. World-systems analysis has been criticized from many sides, and the critics are not always wrong. Saey found both its philosophical and geographical foundations in need of revision. He defends three theses: (1) a distinction must be made between the world-system as a social system (an autopoietic network of social interactions) and the world-system as a geographical system (a complex set of locations that is regionally differentiated by the evolution of the social system); (2) the analysis must be based on a morphogenetic approach; (3) more attention must be paid to the incongruence between political/administrative boundaries and zonal boundaries, and to urban networks.

The book centers on the following research questions:

1. What kind of science is world-systems analysis?

  • Is it a form of unorthodox Marxism?
  • Is it structural determinist? Does it leave room for agency?
  • Is it the appropriate path to penetrate social reality?
  • Is it Eurocentric?
  • Is it functionalist?
  • Is it essentialist? What kind of system is the modern world-system?
  • Is it reductionist? Does it assert that the development of states is determined by economic development, which in turn is determined by class struggle?

2. Did the modern world-system, characterized by the capitalist mode of production, originate in the long sixteenth century? How can it be spatially delineated?

3. Along which social fault lines can antisystemic movements organize?

Why this book matters

The social action field revisits world-systems analysis at a moment when questions of capitalism, state power, democracy and global inequality are once again urgent. Pieter Saey brings geography back to the centre of the debate, while reworking the philosophical and spatial foundations of a tradition that has shaped critical social theory for decades. The book is relevant to readers in geography, political economy, philosophy and social theory.

Praise for the book

Very stimulating to read. A fascinating and very thorough reconstruction of the debates since the seventies, expanding world-system analysis, showing the problems and possible solutions.”

I can only express my admiration for the meticulous argumentation in this book. In the present-day world of fast science it is very exceptional to read a book that resolves so many questions one knows are fundamental but for which one doesn’t get the time anymore.”
