postmodern of or relating to a complex set of reactions to modern philosophy and its presuppositions, as opposed to the kind of agreement on substantive doctrines or philosophical questions that often characterizes a philosophical movement. Although there is little agreement on precisely what the presuppositions of modern philosophy are, and disagreement on which philosophers exemplify these presuppositions, postmodern philosophy typically opposes foundationalism, essentialism, and realism. For Rorty, e.g., the presuppositions to be set aside are foundationalist assumptions shared by the leading sixteenth-, seventeenth-, and eighteenth-century philosophers. For Nietzsche, Heidegger, Foucault, and Derrida, the contested presuppositions to be set aside are as old as metaphysics itself, and are perhaps best exemplified by Plato. Postmodern philosophy has even been characterized, by Lyotard, as preceding modern philosophy, in the sense that the presuppositions of philosophical modernism emerge out of a disposition whose antecedent, unarticulated beliefs are already postmodern. Postmodern philosophy is therefore usefully regarded as a complex cluster concept that includes the following elements: an anti- (or post-) epistemological standpoint; anti-essentialism; anti-realism; anti-foundationalism; opposition to transcendental arguments and transcendental standpoints; rejection of the picture of knowledge as accurate representation; rejection of truth as correspondence to reality; rejection of the very idea of canonical descriptions; rejection of final vocabularies, i.e., rejection of principles, distinctions, and descriptions that are thought to be unconditionally binding for all times, persons, and places; and a suspicion of grand narratives, metanarratives of the sort perhaps best illustrated by dialectical materialism. In addition to these things postmodern philosophy is ‘against,’ it also opposes characterizing this menu of oppositions as relativism, skepticism, or nihilism, and it rejects as ‘the metaphysics of presence’ the traditional, putatively impossible dream of a complete, unique, and closed explanatory system, an explanatory system typically fueled by binary oppositions. On the positive side, one often finds the following themes: its critique of the notion of the neutrality and sovereignty of reason – including insistence on its pervasively gendered, historical, and ethnocentric character; its conception of the social construction of word–world mappings; its tendency to embrace historicism; its critique of the ultimate status of a contrast between epistemology, on the one hand, and the sociology of knowledge, on the other hand; its dissolution of the notion of the autonomous, rational subject; its insistence on the artifactual status of divisions of labor in knowledge acquisition and production; and its ambivalence about the Enlightenment and its ideology. Many of these elements or elective affinities were already surfacing in the growing opposition to the spectator theory of knowledge, in Europe and in the English-speaking world, long before the term ‘postmodern’ became a commonplace. In Anglophone philosophy this took the early form of Dewey’s (and pragmatism’s) opposition to positivism, early Kuhn’s redescription of scientific practice, and Wittgenstein’s insistence on the language-game character of representation; critiques of ‘the myth of the given’ from Sellars to Davidson and Quine; the emergence of epistemology naturalized; and the putative description-dependent character of data, tethered to the theory dependence of descriptions (in Kuhn, Sellars, Quine, and Arthur Fine – perhaps in all constructivists in the philosophy of science). In Europe, many of these elective affinities surfaced explicitly in and were identified with poststructuralism, although traces are clearly evident in Heidegger’s (and later in Derrida’s) attacks on Husserl’s residual Cartesianism; the rejection of essential descriptions (Wesensanschauungen) in Husserl’s sense; Saussure’s and structuralism’s attack on the autonomy and coherence of a transcendental signified standing over against a selftransparent subject; Derrida’s deconstructing the metaphysics of presence; Foucault’s redescriptions of epistemes; the convergence between French- and English-speaking social constructivists; attacks on the language of enabling conditions as reflected in worries about the purchase of necessary and sufficient conditions talk on both sides of the Atlantic; and Lyotard’s many interventions, particularly those against grand narratives. Many of these elective affinities that characterize postmodern philosophy can also be seen in the virtually universal challenges to moral philosophy as it has been understood traditionally in the West, not only in German and French philosophy, but in the reevaluation of ‘the morality of principles’ in the work of MacIntyre, Williams, Nussbaum, John McDowell, and others. The force of postmodern critiques can perhaps best be seen in some of the challenges of feminist theory, as in the work of Judith Butler and Hélène Cixous, and gender theory generally. For it is in gender theory that the conception of ‘reason’ itself as it has functioned in the shared philosophical tradition is redescribed as a conception that, it is often argued, is (en)gendered, patriarchal, homophobic, and deeply optional. The term ‘postmodern’ is less clear in philosophy, its application more uncertain and divided than in some other fields, e.g., postmodern architecture. In architecture the concept is relatively clear. It displaces modernism in assignable ways, emerges as an oppositional force against architectural modernism, a rejection of the work and tradition inaugurated by Walter Gropius, Henri Le Corbusier, and Mies van der Rohe, especially the International Style. In postmodern architecture, the modernist principle of abstraction, of geometric purity and simplicity, is displaced by multivocity and pluralism, by renewed interest in buildings as signs and signifiers, interest in their referential potential and resources. The modernist’s aspiration to buildings that are timeless in an important sense is itself read by postmodernists as an iconography that privileges the brave new world of science and technology, an aspiration that glorifies uncritically the industrial revolution of which it is itself a quintessential expression. This aspiration to timelessness is displaced in postmodern architecture by a direct and self-conscious openness to and engagement with history. It is this relative specificity of the concept postmodern architecture that enabled Charles Jencks to write that ‘Modern Architecture died in St. Louis Missouri on July 15, 1972 at 3:32 P.M.’ Unfortunately, no remotely similar sentence can be written about postmodern philosophy.
