Posthumanist criticism questions the centrality and stability of the human subject that traditionally anchors literary criticism. This approach examines how literature challenges humanist assumptions, exploring distributed agency, non-human consciousness, and the decentering of anthropocentric perspectives in narrative and form.
Your post-structuralist prerequisite already began the work of decentering the subject — Derrida showed that meaning is not generated by a stable authorial consciousness but by a system of differences; Foucault showed that what counts as a subject is itself a historical and discursive construction. Posthumanism continues this decentering but takes a different direction. Where post-structuralism focused on language, discourse, and the internal instability of the human subject, posthumanism focuses on the human's position *in relation to the world*: to other species, to technologies, to environments, to matter itself.
The foundational challenge posthumanism poses is to humanism as a philosophical and literary tradition. Humanism (as the target of critique here) assumes that the human is the origin and measure of meaning, that human consciousness is the center from which understanding radiates outward, and that nonhuman entities are backdrop or resource. Literary criticism in this tradition asks: what does the text say about *human* experience? What does it reveal about the *human* condition? Posthumanism asks whether those questions are the right starting point. If an ecosystem is collapsing, if a virus is reorganizing social life, if an algorithm is shaping political discourse, where is the "human experience" that is supposed to be literature's primary subject?
Distributed agency is one of the most productive posthumanist concepts for literary analysis. The philosopher Jane Bennett and the sociologist Bruno Latour (in different but related traditions) argue that agency — the capacity to act, to make things happen — is not confined to human subjects but is distributed across networks of human and nonhuman actors. A river, a storm, an oil spill, a bacterium all have "agency" in the sense that they resist, redirect, and transform human plans and stories. When you apply this lens to a text, you ask: what nonhuman actors have causal force in this narrative? What does the story look like if you trace the agency of the environment, the technology, the animal, the disease — rather than treating them as backdrop against which human dramas unfold? Mary Shelley's monster in *Frankenstein* is a canonical example: the creature is not simply a reflection of human anxieties but a nonhuman (or parahuman) entity whose agency disrupts every human attempt to contain or categorize it.
The relationship to your prerequisite knowledge of discourse and power is important. Foucault showed that subject positions are produced by power-knowledge regimes. Posthumanism extends this by asking: what subject positions are possible if the boundary between human and nonhuman is drawn differently? Literature has always explored this at the margins — animal narrators, robot consciousness, ecological perspectives, collective or distributed minds — but posthumanist criticism reads these not as fanciful departures from normal subject-centered narrative but as serious explorations of what kinds of beings can have stories, what kinds of consciousness can be the center of a narrative, and what kinds of relationships between human and nonhuman the form of the text itself makes thinkable. The formal question — how does a novel narrate nonhuman perspective? — is inseparable from the political one: what assumptions about mind, agency, and value does that formal choice challenge or reproduce?
