Foucauldian discourse analysis examines how knowledge, truth, and subjectivity are produced through historically specific systems of language and practice called discourses. In literary studies, this means asking not only what a text means but what regimes of truth it participates in—how it constructs subjects, normalizes certain experiences as natural, and excludes others as deviant, mad, or criminal. Discourse analysis treats literary and non-literary texts symmetrically as parts of the same discursive formation. Foucault's concepts of power/knowledge (power does not merely repress but produces knowledge and subjects), the author-function (the author is a historically contingent principle for classifying and regulating texts), and genealogy (tracing the contingent historical conditions of present-day norms) have transformed how critics think about the relationship between literature and social institutions.
Read Foucault's 'What Is an Author?' alongside the relevant portions of The History of Sexuality volume 1 to see how discourse analysis works on both textual and social phenomena. Then trace a single term (madness, sexuality, criminality) across several texts from the same historical period, asking how the term functions as a site of power/knowledge production rather than as a descriptor of a pre-existing reality.
You have already encountered discourse analysis as a method for examining how language constructs social reality, and you have read Foucault alongside post-structuralism's claim that meaning is unstable and produced through systems of difference. This topic brings those threads together by asking a more pointed question: if language produces meaning, what produces language? Foucault's answer is power — not power as a thing that some people possess and others lack, but power as a dispersed network of relations that operates through the very categories we use to think.
The concept of power/knowledge is the center of Foucauldian discourse analysis. Power does not simply suppress or distort knowledge; it actively produces knowledge. When psychiatry in the nineteenth century defined some people as mentally ill, it was not merely reporting a pre-existing medical fact — it was constituting a new category of person, generating new institutions (the asylum), new practices (clinical observation), and new subjects (the patient). The discourse of mental illness gave psychiatrists authority precisely because it produced the objects it claimed only to describe. This is what Foucault means when he says power and knowledge are not opposed but mutually constitutive. Applied to literature, this means asking: what subject positions does this text produce? What does it make it possible to say, and what does it render unsayable?
The author-function extends this analysis to the practice of literary interpretation itself. When we ask 'What did Dickens mean by this?' we are treating the author as the privileged source of textual meaning — a figure who guarantees that interpretation can, in principle, be correct or incorrect. Foucault argues that this figure is historically specific: the idea that texts belong to named individuals, that authors can be held legally responsible for their words, that a text's meaning is anchored in its origin rather than its circulation — all of these are features of a particular discursive formation, not eternal truths about how language works. Literary criticism that relies on authorial intent is, from this perspective, reproducing a particular regime of truth rather than accessing meaning itself.
Genealogy provides the method for tracing how these regimes came to seem natural. Rather than asking 'what does this literary tradition mean?' genealogy asks 'how did this tradition come to count as literature at all, and what was excluded in the process?' This is not merely a historical question — it is an intervention in the present. By showing that the canon, the author, the text, the reader, and the critical apparatus are all contingent historical formations, genealogical criticism opens space for asking what interests those formations serve and what alternative configurations might look like.
When you apply these concepts in practice, the key move is to treat the text not as an isolated object to be interpreted but as a node in a discursive formation. Ask what other texts, institutions, practices, and subject positions surround it. Ask what it makes possible to know, say, and be, and what it forecloses. The question is not 'what does this text mean?' but 'what work does this text do, for whom, and within what regime of truth?'
