Lecture 11-1: Postmodern Philosophy's Challenge to Enlightenment Reason

Two passages frame this lecture's central question — whether a claim to state the truth, plainly and finally, can be made honestly, or whether every such claim is really an exercise of power dressed up as neutral description.

John 18:37-38 records the trial of Jesus before Pilate: "Pilate therefore said to him, 'Are you a king then?' Jesus answered, 'You say that I am a king. For this reason I have been born, and for this reason I have come into the world, that I should testify to the truth. Everyone who is of the truth listens to my voice.' Pilate said to him, 'What is truth?' When he had said this, he went out again to the Jews, and said to them, 'I find no basis for a charge against him.'" (World English Bible) Pilate's question is not idle. He asks it of a man standing before him with no army, no office, and no claim on Roman power, who has just asserted that he came into the world for the specific purpose of "testifying to the truth." The Gospel does not record Jesus answering the question directly — the narrative simply moves on, with Pilate walking away from the one figure in the scene the Gospel itself presents as the answer. Readers of this lecture should notice, without forcing the connection, that a Roman governor's skeptical dismissal of a truth-claim made by someone with no institutional power to back it is at least an interesting point of contact with a modern suspicion that all truth-claims are actually about power — even though, as this lecture will stress, that is not the same claim Foucault makes, and John's Gospel is not making a postmodern argument.

Ecclesiastes 1:2 offers a very different, and older, kind of skepticism: "'Vanity of vanities,' says the Preacher; 'Vanity of vanities, all is vanity.'" (WEB) The Hebrew word rendered "vanity" (hevel) carries a sense closer to "vapor" or "breath" — something that cannot be grasped or pinned down, not exactly "meaningless" in the modern sense but "elusive," "fleeting," resistant to the kind of confident, totalizing account of life's meaning that Qoheleth's book spends its length testing and finding wanting. It would be a mistake to read Ecclesiastes as a proto-postmodern text; its skepticism operates inside a settled conviction that God exists and will judge (Eccl 12:13-14), which is precisely the kind of metaphysical confidence postmodern philosophy is suspicious of in a different way. But the two texts together are useful for this lecture's purpose: they show that a wariness of easy, totalizing claims to grasp the whole truth of things is not a uniquely modern invention, even though the particular form Lyotard, Derrida, and Foucault gave it — directed specifically at Enlightenment reason's own self-image — is.

What a "metanarrative" is, and Lyotard's diagnosis

Jean-François Lyotard's 1979 report The Postmodern Condition: A Report on Knowledge, commissioned as a study of the state of knowledge in advanced societies, gave this whole intellectual movement its most quoted single sentence: "I define postmodern as incredulity toward metanarratives." A metanarrative, in Lyotard's usage, is not simply any large story; it is a story that legitimates itself — that claims to be not just one account among others but the account that grounds and justifies all the smaller, local stories and practices underneath it, by appeal to some universal standard (Reason, History, Progress, human Emancipation) that stands, supposedly, outside any particular time, place, or interest.

Lyotard identified two especially influential Enlightenment-era metanarratives. The first is the narrative of emancipation: the story, running from the French Revolution through nineteenth-century liberalism and socialism, that humanity is a single subject progressively freeing itself from ignorance and oppression through the exercise of reason, and that a given political or intellectual project earns its legitimacy by its contribution to that universal emancipatory movement. The second is the narrative of speculative unity: the story, associated especially with Hegel's system (which chapter 1's third lecture already introduced), that all human knowledge forms, or is moving toward, a single unified, rationally coherent whole — that the sciences, the arts, and philosophy are chapters in one story of Spirit coming to know itself.

Lyotard's claim was that by the late twentieth century, confidence in both kinds of story had collapsed — not primarily because anyone had refuted them philosophically, but because the historical experience of the twentieth century (two world wars, the Holocaust, Stalinism, the uneven and often violent record of "progress" delivered by industrial modernity) had made the grand, confident story simply incredible to people living after it. In its place, Lyotard argued, knowledge in postmodern societies increasingly legitimates itself locally and pragmatically — smaller, more modest, more explicitly situated accounts (what he called "little narratives," petits récits) replacing the single overarching story that used to hold everything together. Lyotard's own later work grew more cautious about the term "postmodern" itself, worried that it too easily became one more totalizing label — a point worth remembering before treating "postmodernism" as a single settled school with one agreed content, since Lyotard, Derrida, and Foucault worked independently, asked different questions, and would not necessarily have accepted being grouped together as a single movement.

Derrida and the instability of meaning

Jacques Derrida's practice of deconstruction is harder to summarize briefly than Lyotard's thesis, and this lecture states it at the introductory level appropriate to a history-of-doctrine course rather than a philosophy course, since Derrida's own writing resists easy paraphrase by design. Derrida's central claim, developed across works including Of Grammatology (1967) and Writing and Difference (1967), is that Western philosophy since Plato has operated with what he called "logocentrism" — a persistent assumption that spoken language, and behind it a stable, fully present meaning in the speaker's mind, is primary, while written language is a secondary, derivative copy. Derrida argued this hierarchy cannot be sustained: writing displays, more visibly than speech, a feature that actually belongs to all language — that a word's meaning is never simply and fully "present," graspable all at once, but is generated by its difference from other words in an endless chain of reference (a process Derrida named with the coined term différance, playing on the French words for both "differing" and "deferring"). A text's meaning, on this account, is never finally fixed by the author's intention; it is always open to being read against itself, its own unstated assumptions and internal tensions exposed by a sufficiently careful reading — which is roughly what "to deconstruct" a text means in Derrida's own practice.

The theological stakes of this claim are not hard to see even before any theologian takes it up: if no text's meaning is ever finally stable and fully present, then a doctrine of Scripture that depends on a text delivering one determinate, authoritative meaning faces a real philosophical challenge from a very different direction than Bultmann's demythologization (chapter 4) or historical-critical method's challenge to a text's factual claims (chapter 2). Derrida's own relationship to religious tradition, particularly late in his career, was considerably more complex and more engaged with what he called a "religion without religion" than a simple "deconstruction is anti-religious" reading suggests — a nuance worth flagging honestly rather than flattening, in keeping with this course's caution against caricaturing a position to make it easy to critique.

Foucault and the entanglement of knowledge and power

Michel Foucault's genealogical method, developed across studies including Discipline and Punish (1975) and The History of Sexuality (1976), asked a historical question with a philosophically unsettling implication: not "is this claim to knowledge true?" but "under what historical conditions, and through what institutions and practices of power, did this particular way of dividing knowledge from ignorance, sanity from madness, normal from deviant, come to seem simply obvious?" Foucault's studies of the modern prison, the asylum, and the clinic traced how what counted as objective, scientific knowledge in each domain was inseparable from new technologies of disciplinary power — surveillance, classification, examination — that were simultaneously producing new kinds of subjects (the "criminal," the "insane," the "deviant") who could then be known, in exactly the terms those same institutions had already defined.

Foucault's coined phrase "power/knowledge" names this entanglement directly: not that truth does not exist, and not (this is a common misreading) that Foucault denied there was any difference between true and false claims, but that the very apparatus that lets a society sort claims into "known/true" and "unknown/false" categories is never a neutral, disinterested mechanism standing outside power — it is itself a site where power operates, producing what will count as knowledge as much as discovering it. Applied to Enlightenment reason's own self-presentation as a neutral, disinterested arbiter of truth standing above every particular interest, Foucault's method suggests that this self-presentation is itself a historically specific and interested claim, not the view from nowhere it presents itself as.

What is, and is not, being claimed

It is worth being precise about what this chapter's briefing calls "a philosophical challenge to Enlightenment reason's own claimed neutrality and universality" — precise both because the claim is genuinely radical and because it is frequently overstated by both critics and enthusiasts. None of the three philosophers treated here denied that some claims are better supported by evidence than others, that careful argument is preferable to careless argument, or that all truth-claims are simply and interchangeably fictions with no difference between them — a crude reading sometimes summarized (usually by critics rather than by the philosophers themselves) as "postmodernism says there is no truth." What Lyotard, Derrida, and Foucault each argued, in their different ways, is narrower and in some ways harder to dismiss: that the particular Enlightenment claim to have found a standpoint of pure reason, free of historical location, cultural particularity, and interested power, from which all other claims to knowledge can be neutrally adjudicated, is itself a historically specific and culturally located story — one metanarrative among the possible ones, not the view from outside all narratives it presented itself as.

This is the same Enlightenment reason chapter 1 introduced as modern theology's founding problem, and the challenge this lecture has described is aimed at that reason's own claimed standing to judge, rather than at any single doctrine reason might have judged. It is exactly this target — reason's claim to neutrality, not reason itself, and certainly not any particular Christian doctrine directly — that made postmodern philosophy available to theology in two sharply different ways, worked out in the rest of this chapter: as an unexpected ally against the Enlightenment's own universalizing pretensions (11-2 and 11-3), and as grounds for relativizing every tradition's claim to unique finality, Christianity's own included (11-4).
