On Decoloniality: Concepts, Analytics, Praxis

Overview

On Decoloniality: Concepts, Analytics, Praxis, published in 2018, is the inaugural volume of the Duke University Press series “On Decoloniality.” Written in two complementary parts by Walter D. Mignolo, a semiotician and cultural theorist at Duke University, and Catherine E. Walsh, an activist-intellectual based at the Universidad Andina Simón Bolívar in Ecuador, the book sets out to define decoloniality as simultaneously a way of thinking, an analytical framework, and a lived practice.

The book speaks to a central question: how do the structures of colonial power persist long after formal colonial rule has ended, and what does it mean to think, live, and act outside them?

Core Argument

Mignolo and Walsh argue that modernity and coloniality are inseparable. What the Western tradition calls “modernity,” the progress of reason, science, and liberal governance, has a darker underside: coloniality, the logic of racial hierarchy, epistemic domination, and the extraction of labour and nature that made modernity possible and continues to sustain it. This is what Mignolo, drawing on the work of Aníbal Quijano, calls the “colonial matrix of power.”

The colonial matrix operates through three interlocking pillars: racism, sexism, and the domination of nature. These are not incidental to the modern world order but constitutive of it. The book argues that understanding contemporary global inequality, including the structures of international aid and humanitarian action, requires grasping this matrix and its persistence.

Decoloniality, then, is not simply opposition or resistance. It is “the ongoing creation of ways of thinking, of ways of knowing, of ways of sensing, being, and living outside coloniality, outside or despite coloniality, and in its borders, its fissures, and its cracks.” It is an option, not a mission: it does not seek to replace one universal system with another, but to create space for what the authors call pluriversality, the coexistence of multiple knowledge systems and ways of being.

Structure

The book is organised in two parts, each written independently but in dialogue with the other.

Part I, by Catherine E. Walsh, is grounded in her decades of work with Indigenous and Afro-descendant movements in Ecuador and Latin America. It explores decoloniality as praxis: the concrete struggles, pedagogies, and forms of re-existence through which communities are creating alternatives to the colonial order. Walsh draws on concepts of interculturality, insurgency, and decolonial pedagogy, grounding them in specific social movements and lived experiences.

Part II, by Walter D. Mignolo, develops the conceptual and analytical architecture of decoloniality. He traces the modernity/coloniality/decoloniality triad, analyses the invention of racial and gender hierarchies as instruments of colonial power, examines the Eurocentric structure of global knowledge production, and argues for “epistemic disobedience”: the refusal to accept Western epistemology as universal or normative.

Significance

On Decoloniality has become a benchmark text in decolonial studies and is increasingly cited in debates about the future of the humanitarian system and the localisation of aid. Its relevance to humanitarianism is direct, even where the book does not address the sector explicitly.

The book challenges the epistemic foundations on which much of international humanitarian and development practice rests: the assumption that Western knowledge systems, governance models, and standards of accountability are neutral or universal rather than products of a particular history of power. It asks who defines what counts as a crisis, what constitutes an appropriate response, and whose knowledge is valued in the process. These are precisely the questions at the heart of the localisation and decolonisation debates in the humanitarian sector.

The concept of the colonial matrix of power provides a framework for understanding why the structures of international aid so persistently reproduce the inequalities they claim to address: why funding flows from North to South through layers of intermediaries, why accountability runs upward to donors rather than downward to affected communities, and why the knowledge and priorities of local actors are systematically subordinated to those of international organisations.

Walsh’s emphasis on re-existence, on communities creating new forms of life and organisation from within the cracks of the colonial order, offers an alternative to the humanitarian language of “resilience,” which often implies adaptation within existing structures rather than transformation of them.
