QUICK SUMMARY

Postmodernism — a loose, contested, and internally diverse intellectual movement that emerged from French philosophy and literary theory in the 1960s-1980s — is characterized by a thoroughgoing skepticism toward universal truths, grand narratives, fixed meanings, and the Enlightenment project of rational progress. Its key figures include: Jacques Derrida (1930-2004), who developed deconstruction — a method of reading texts that reveals the unstable, self-undermining binary oppositions (speech/writing, presence/absence, nature/culture) structuring Western thought, and introduced the concept of différance (meaning is always deferred and differential, never fully present); Michel Foucault (1926-1984), whose historical analyses of madness, medicine, punishment, and sexuality revealed how systems of power-knowledge constitute the very subjects and truths they claim merely to describe; and Jean-François Lyotard (1924-1998), who defined the postmodern condition as "incredulity toward metanarratives" — the collapse of grand explanatory stories (Marxism, Christianity, Enlightenment progress, science as liberation) that had legitimated modern institutions. Other major figures include Jean Baudrillard (simulacra and hyperreality), Gilles Deleuze (difference, rhizome, nomadism), and Judith Butler (gender performativity). Postmodernism has profoundly influenced literary criticism, cultural studies, architecture, art, sociology, and political theory, while provoking intense criticism from analytic philosophers, scientists, and political theorists who accuse it of relativism, obscurantism, and undermining the rational foundations of democratic discourse.

1. VERIFIED CLAIMS (Tier 1 — Peer-Reviewed / Established)

1.1 Jacques Derrida (1930-2004)

• Born in El-Biar, French Algeria; studied at the École Normale Supérieure in Paris; taught at the ENS, Yale, and UC Irvine:
• Deconstruction (not a method or theory but a practice of critical reading): Derrida argued that Western philosophy is structured by binary oppositions (speech/writing, soul/body, inside/outside, nature/culture) in which one term is always privileged over the other — deconstruction reveals that these hierarchies are unstable and that the "subordinate" term is always already implicated in the "privileged" term
• Différance (a neologism combining "differ" and "defer"): meaning is produced through a play of differences within a system of signs — no sign has a fully present, self-identical meaning; meaning is always already deferred to other signs in an unending chain
• Logocentrism: the Western metaphysical tradition privileges logos (reason, speech, presence) and denigrates writing, supplementarity, and absence — Derrida's Of Grammatology (1967) deconstructs this hierarchy
• "There is nothing outside the text" (il n'y a pas de hors-texte): frequently misinterpreted as denying external reality; Derrida meant that nothing is accessible to us except through some form of textual/semiotic mediation
• Key works: Of Grammatology (1967), Writing and Difference (1967), Margins of Philosophy (1972), Specters of Marx (1993)

1.2 Michel Foucault (1926-1984)

• Born in Poitiers; studied at the ENS under Althusser; held the chair of "History of Systems of Thought" at the Collège de France (1970-1984):
• Archaeology of Knowledge: in early works (Madness and Civilization, 1961; The Order of Things, 1966; The Archaeology of Knowledge, 1969), Foucault analyzed the epistemes — the underlying conceptual frameworks that determine what counts as knowledge in a given era — showing radical discontinuities between historical periods
• Genealogy and Power-Knowledge: in later works (Discipline and Punish, 1975; The History of Sexuality, Vol. 1, 1976), Foucault adopted a Nietzsche-inspired genealogical method, tracing how modern institutions (the prison, the clinic, the school) produce and discipline subjects through practices of surveillance, normalization, and examination:
• Panopticon: Jeremy Bentham's circular prison design (see P_2_10) became Foucault's central metaphor for modern disciplinary society — a system where the possibility of constant surveillance induces self-regulation
• Biopower: the modern state's management of populations through statistics, public health, sexuality, and demographics — power exercised not through sovereign violence but through the regulation of life itself
• Discourse: systems of statements that constitute objects of knowledge — what can be said, thought, and known is determined by discursive formations, not by pre-existing truths

1.3 Jean-François Lyotard (1924-1998)

• The Postmodern Condition: A Report on Knowledge (1979):
• Defined the postmodern as "incredulity toward metanarratives" (grands récits) — the loss of faith in the large-scale legitimating stories of modernity (the Hegelian dialectic, Marxist emancipation, the Enlightenment narrative of progressive rational liberation)
• Knowledge in the postmodern condition is fragmented into heterogeneous "language games" (borrowing from Wittgenstein), each with its own rules of validity — science, ethics, law, art cannot be unified under a single framework
• Performativity: knowledge is increasingly evaluated not by truth but by efficiency and performance (the criterion becomes: "Is it useful?" rather than "Is it true?")

2. CREDIBLE CLAIMS (Tier 2 — Academic / Debated but Supported)

2.1 Baudrillard and Hyperreality

• Jean Baudrillard (1929-2007): argued that in consumer capitalism, signs no longer refer to reality but to other signs — creating a simulacrum (a copy without an original) and a condition of hyperreality in which the distinction between reality and representation collapses:
• Simulacra and Simulation (1981): four stages of the sign — reflecting reality → masking reality → masking the absence of reality → bearing no relation to reality at all

2.2 Judith Butler and Performativity

• Judith Butler (Gender Trouble, 1990): extended postmodern theory to gender, arguing that gender is not a natural attribute but a performative — constituted through repeated, stylized acts rather than expressing a pre-existing identity

3. SPECULATIVE CLAIMS (Tier 3 — Possible but Unverified)

3.1 Post-Truth and Postmodernism

• The relationship between postmodern theory and the contemporary "post-truth" phenomenon is debated: critics argue that postmodern skepticism about objective truth enabled political disinformation; defenders counter that postmodernism analyzed the production of truth claims, not abolish truth itself

4. DUBIOUS CLAIMS (Tier 4 — No Credible Source / Contradicted by Evidence)

4.1 Postmodernism Denies All Truth

• [OVERSIMPLIFIED] Major postmodern thinkers did not claim "there is no truth" — they analyzed how truth is produced, legitimated, and deployed within particular historical and institutional contexts. Foucault's work is deeply empirical; Derrida's deconstruction requires close, rigorous reading
