Epistemic Occlusion

Epistemic Occlusion

Abstract

I introduce the concept of epistemic occlusion to describe a form of epistemic harm that occurs when certain knowledges, frameworks, or epistemic agents are systematically rendered invisible within dominant epistemic practices, not through active silencing or exclusion, but through processes that pre-emptively block their recognition. Unlike testimonial strands of epistemic harms, which concern the unfair downgrading of a speaker's credibility, or hermeneutical strands, which arise from gaps in collective interpretive resources, epistemic occlusion names a prior and more elusive mechanism. It is a structurally produced condition in which certain knowledges or epistemic agents are rendered imperceptible. I argue that epistemic occlusion operates through mechanisms that shape what is seen, taken seriously, or even conceivable as knowledge.

One. Introduction

If we are to create a genealogy of negatively valenced epistemic Xs, it might look like this: in the beginning, there was epistemic occlusion, when certain knowledges and agents were systematically rendered invisible. After that came epistemic resistance, when resistant epistemologies were formed. And then, epistemic exclusion, when these resistant epistemologies were excluded. This is followed by an era of epistemic oppression that is littered with various epistemic Xs - injustices, exploitation, appropriation, ignorances, silencing, etc.

My aim here is to introduce and sketch this genealogically prior concept, epistemic occlusion.

Most accounts of epistemic Xs share a common assumption that marginalised knowers or forms of knowledge are at least visible within the epistemic field, even if they are dismissed, misinterpreted, marginalised, or devalued. What this assumption overlooks is a distinct and pervasive phenomenon. That is, the systematic invisibility of certain knowledges, frameworks, and epistemic agents. This is not merely a failure to take marginalised perspectives seriously, nor a lack of interpretive tools to make sense of them, but a more fundamental filtering-out that occurs before recognition, engagement, or contestation. I call this phenomenon epistemic occlusion.

Epistemic occlusion refers to the structural, often unconscious processes by which particular ways of knowing, speaking, or being are rendered epistemically illegible. Not by being heard and dismissed, but by failing to register as knowable or relevant in the first place. Drawing inspiration from the etymology of occlusion, meaning blockage or obstruction, I argue that certain epistemic pathways are blocked by dominant social, political, and epistemic structures, resulting in a distorted and incomplete epistemic landscape. Unlike epistemic exclusion, which concerns the active marginalisation of individuals and knowledges, or cases of wilful ignorance, which focus on the lack of uptake by dominant audiences, epistemic occlusion highlights how knowers and knowledge claims are structurally precluded from recognition altogether.

The need for this conceptual expansion is both theoretical and practical. Theoretically, epistemic occlusion helps to illuminate a more primary form of epistemic harm that escapes capture by existing categories. Practically, it draws attention to the epistemic architectures, discursive norms, institutional filters, disciplinary gatekeeping, and inherited colonial frameworks that shape what is seen, what counts, and who matters in our epistemic lives. By naming and analysing epistemic occlusion, we can better understand how even efforts at inclusion or representation may leave the deepest forms of epistemic harm intact.

This paper proceeds as follows. In section two, I conceptualise epistemic occlusion and distinguish it from related concepts in the literature. In section three, I explore the mechanisms through which epistemic occlusion operates, including linguistic norms, norms of patriarchy, and norms of modernity and progress. In section four, I look at two illustrative cases of epistemic occlusion. In section five, I highlight four non-exhaustive ways to combat epistemic occlusion that include attentional responsibility, epistemic re-mapping, decolonial critique, and non-assimilative recognition.
