Intersectionality’s Philosophical Dimensions: Exploring Theories by Kimberle Crenshaw and Leslie McCall

When Kimberlé Crenshaw introduced the term intersectionality in her landmark 1989 essay, she wasn’t just adding another word to academic vocabulary. She was exposing a fundamental flaw in how society – and its legal, political, and social systems – understood oppression. The experience of a Black woman, she argued, could not be fully captured by analyzing racism and sexism separately; the two systems interlock and compound each other in ways that create a distinct, more complex form of disadvantage. Decades later, this insight has grown into one of the most debated and applied frameworks in the social sciences. Understanding its philosophical core – particularly through the theories of Crenshaw and sociologist Leslie McCall – is essential to grasping how power and inequality actually operate in the real world.

The origins and purpose of intersectionality 🔗

Intersectionality was coined by Kimberlé Crenshaw, a prominent civil rights advocate and critical race theory scholar, in her 1989 article Demarginalizing the Intersection of Race and Sex. Her goal was to address experiences of oppression that existing legal and social frameworks simply could not explain. She followed this up in her 1991 essay Mapping the Margins: Intersectionality, Identity Politics, and Violence Against Women of Color, where she extended the framework to examine how race, gender, and class shape the experiences of women of color facing domestic violence and rape.

At its core, intersectionality originated in critical race studies and examines how different forms of oppression – such as racism, sexism, and classism – combine and interact to produce layered systems of disadvantage and privilege. It was never meant to simply catalog social identities. As Crenshaw herself has described it, intersectionality is a lens for seeing where power collides and interlocks – not a grand theory of everything, but a precise analytical tool for understanding how systems of inequality reinforce one another.

Crenshaw’s structural intersectionality 🔗

Structural intersectionality refers to how people are marginalized by the combined and reinforcing effects of multiple overlapping systems of power – legal, economic, institutional, and social. It is not enough to ask whether someone faces racism or sexism; structural intersectionality asks how both systems simultaneously shape a person’s position in the world.

Crenshaw illustrated this with a concrete legal example. She demonstrated how antidiscrimination law historically defined the boundaries of race and sex discrimination through prototypical representatives – white women for gender cases and Black men for race cases. This meant Black women, whose experiences were shaped by both categories at once, often fell through the cracks of legal protection entirely. An employer could avoid a race discrimination claim by pointing to Black male employees, and avoid a sex discrimination claim by pointing to white female employees – leaving Black women with no legal recourse even when they were clearly being discriminated against.

This example reveals something philosophically important: structural intersectionality is not just about individuals having multiple identities. It is about how institutions are themselves structured in ways that make certain forms of compounded disadvantage invisible. The burden is not merely additive – it is multiplicative, producing a distinct form of marginalization that neither framework alone can capture.

Crenshaw also highlighted this dynamic in the context of immigration policy. She showed how the marriage fraud provisions of the Immigration and Nationality Act, designed to burden immigrant spouses seeking permanent resident status, compounded the vulnerability of women already disadvantaged by other structures of domination – leaving them exposed to both immigration enforcement and domestic abuse simultaneously. The harm was not produced by either system acting alone, but by their intersection.

Crenshaw’s political intersectionality 🔗

While structural intersectionality focuses on how systems of power marginalize people, political intersectionality addresses a different but equally critical problem: how political and social movements themselves can reproduce exclusion. Crenshaw observed that movements for racial justice and movements for gender equality have historically focused on the concerns of those with only one subordinated identity – Black men in anti-racist politics, white women in feminist politics – sidelining those who exist at the intersection of both.

Black women, for instance, found themselves marginalized in civil rights movements where gender equality was treated as a secondary concern, and marginalized in women’s movements where race was either ignored or subordinated to gender. They could not find a space in either movement that reflected the full complexity of their experience.

Political intersectionality therefore calls for a fundamentally different approach to social justice organizing. Intersectional thinking opens the way to more inclusive and coalitional social movements that refuse to rank oppressions or treat them as competing priorities. It insists that movements for racial justice must also be movements for gender equity, and vice versa – because these struggles are not separable in the lived experiences of people who face both simultaneously. Crenshaw’s political intersectionality is, at its heart, a critique of single-issue politics and a demand for coalition-building that takes the full range of identities seriously.

Leslie McCall’s contribution: mapping intersectional approaches 🔗

While Crenshaw established the foundational concepts of intersectionality, sociologist Leslie McCall made a different but equally significant contribution. In her influential 2005 article The Complexity of Intersectionality, published in the journal Signs, McCall argued that intersectionality had generated new methodological challenges for researchers. Different scholars were studying it in fundamentally different ways, with different philosophical assumptions about the nature of categories like race and gender. McCall identified three distinct approaches – anti-categorical, intra-categorical, and inter-categorical – that together represent a continuum for how researchers engage with social categories.

Anti-categorical complexity 🔗

At one end of the continuum sits the anti-categorical approach, rooted in postmodernist and poststructuralist theory. This approach challenges the very validity of social categories like “woman,” “Black,” or “working class.” According to McCall, scholars in this camp understand categories as artificial and exclusionary, arguing that the process of categorization itself reinforces the hierarchies of power that produce inequality.

The philosophical logic here is that to name a category is to construct and police its boundaries, which in turn produces exclusion. By deconstructing categories rather than using them, this approach seeks to dismantle the symbolic and material violence rooted in those boundaries. McCall notes that this approach has been quite successful in generating skepticism about the use of categories, though critics argue it can undermine the practical project of documenting and addressing real-world inequalities.

Intra-categorical complexity 🔗

The intra-categorical approach sits in the middle of McCall’s continuum. Rather than rejecting categories outright or using them wholesale, it focuses on groups that exist at neglected points of intersection – people whose identities cross the boundaries of traditionally constructed social groups. This perspective seeks to complicate and use existing analytical categories in a more critical way, treating them as real but also as imperfect constructs that can obscure the diversity of experience within groups.

McCall considers this approach the historical origin of intersectional analysis itself – it grew from the lived experiences of women of color who recognized that neither “women” nor “Black people” as unified categories captured their specific form of marginalization. The intra-categorical approach is particularly well-suited to qualitative and ethnographic research, which allows researchers to listen closely to individual voices and reveal the heterogeneity hidden within broad social categories.

Inter-categorical complexity 🔗

The inter-categorical approach, which McCall endorses in her own empirical work, occupies the opposite end of the continuum from the anti-categorical approach. This approach requires adopting existing analytical categories strategically, using them with a critical awareness of their limitations but maintaining them as the center of analysis. The key question it asks is: what are the relationships of inequality between social groups, and how do those relationships change across different contexts?

Rather than focusing on a single group or deconstructing categories, the inter-categorical approach uses multiple categories simultaneously to map patterns of inequality across society. Inter-categorical projects are interested in examining how oppressive processes drive across-group differences – for instance, comparing wage gaps among white men, white women, Black men, and Black women to reveal how race and gender together structure economic inequality. This approach analyzes relationships between groups rather than treating categories as additive, showing how different axes of inequality interact to produce outcomes that cannot be explained by any single category alone.

Why these philosophical dimensions matter 🔗

Together, Crenshaw’s and McCall’s theoretical contributions reframe how we understand power, identity, and inequality. They do not simply describe social complexity – they provide tools for analyzing it systematically. Intersectional thinking has disrupted hierarchies of oppression that treat one form of injustice as primary – such as the claim that class oppression must always trump all others – and replaced that single-axis thinking with a more nuanced understanding of how multiple systems of power operate simultaneously.

Philosophically, intersectionality challenges what Crenshaw called “single-axis frameworks” – approaches that analyze race, gender, or class in isolation. Crenshaw used intersectionality to demonstrate the limitations of single-axis frameworks and how they narrow the scope of institutional transformation, truncate advocacy around racism and patriarchy, and undermine possibilities for meaningful solidarity by placing resistance movements at odds with each other.

McCall’s three approaches add an important methodological layer to this philosophical critique. They show that there is no single correct way to study intersectionality – the appropriate approach depends on the research question, the context, and what the scholar prioritizes. The three approaches together illustrate that different methodologies produce different knowledge – and that intersectional research must be self-aware about the philosophical assumptions embedded in its methods.

Intersecting power relations produce complex, interdependent social inequalities, and the social location of individuals within those intersecting power structures shapes both their experiences and their perspectives on the social world. This is why intersectionality remains indispensable: it insists that any serious analysis of hierarchy must account for the ways in which race, gender, class, sexuality, and other axes of identity do not operate in parallel, but in tandem – reinforcing, compounding, and sometimes contradicting one another in ways that only become visible when we look at their intersection.

Intersectionality and the broader project of social justice 🔗

Crenshaw’s structural and political intersectionality, alongside McCall’s methodological framework, together form a powerful philosophical toolkit. They move analysis beyond description toward diagnosis – not just identifying that inequality exists, but explaining how it is produced and reproduced by interlocking systems. Intersectionality helps researchers and activists understand inequalities not only between groups but within them, offering a corrective to the tendency of social movements to organize around the most privileged members of any subordinated group.

This philosophical project is not merely academic. Intersectionality has transformed conversations about inequality and inspired new debates across disciplines – from law and political science to public health and education. The axes of inequality pertaining to gender, race, and class are interlocked, dependent upon one another, and mutually constituted, meaning that policies addressing only one dimension are unlikely to produce lasting change for those most marginalized. Effective advocacy and policymaking must therefore take the full complexity of intersecting identities seriously – not as a complication to be managed, but as a fundamental feature of how inequality works.

What do you think? If single-axis frameworks – focusing on just race, or just gender, or just class – are philosophically insufficient for understanding inequality, how should institutions redesign their anti-discrimination policies to reflect the complexity that Crenshaw’s structural intersectionality reveals? And between McCall’s three approaches, which do you think is most useful for studying inequality in your own social context, and why?
