Lyotard Jean-François (1924–98), French philosopher, a leading representative of the movement known in the English-speaking world as post-structuralism. Among major post-structuralist theorists (Gilles Deleuze [1925–97], Derrida, Foucault), Lyotard is most closely associated with postmodernism. With roots in phenomenology (a student of Merleau-Ponty, his first book, Phenomenology [1954], engages phenomenology’s history and engages phenomenology with history) and Marxism (in the 1960s Lyotard was associated with the Marxist group Socialisme ou Barbarie, founded by Cornelius Castoriadis [1922–97] and Claude Lefort [b.1924]), Lyotard’s work has centered on questions of art, language, and politics. His first major work, Discours, figure (1971), expressed dissatisfaction with structuralism and, more generally, any theoretical approach that sought to escape history through appeal to a timeless, universal structure of language divorced from our experiences. Libidinal Economy (1974) reflects the passion and enthusiasm of the events of May 1968 along with a disappointment with the Marxist response to those events. The Postmodern Condition: A Report on Knowledge (1979), an occasional text written at the request of the Quebec government, catapulted Lyotard to the forefront of critical debate. Here he introduced his definition of the postmodern as ‘incredulity toward metanarratives’: the postmodern names not a specific epoch but an antifoundationalist attitude that exceeds the legitimating orthodoxy of the moment. Postmodernity, then, resides constantly at the heart of the modern, challenging those totalizing and comprehensive master narratives (e.g., the Enlightenment narrative of the emancipation of the rational subject) that serve to legitimate its practices. Lyotard suggests we replace these narratives by less ambitious, ‘little narratives’ that refrain from totalizing claims in favor of recognizing the specificity and singularity of events. Many, including Lyotard, regard The Differend (1983) as his most original and important work. Drawing on Wittgenstein’s Philosophical Investigations and Kant’s Critique of Judgment, it reflects on how to make judgments (political as well as aesthetic) where there is no rule of judgment to which one can appeal. This is the différend, a dispute between (at least) two parties in which the parties operate within radically heterogeneous language games so incommensurate that no consensus can be reached on principles or rules that could govern how their dispute might be settled. In contrast to litigations, where disputing parties share a language with rules of judgment to consult to resolve their dispute, différends defy resolution (an example might be the conflicting claims to land rights by aboriginal peoples and current residents). At best, we can express différends by posing the dispute in a way that avoids delegitimating either party’s claim. In other words, our political task, if we are to be just, is to phrase the dispute in a way that respects the difference between the competing claims. In the years following The Differend, Lyotard published several works on aesthetics, politics, and postmodernism; the most important may well be his reading of Kant’s third Critique in Lessons on the Analytic of the Sublime (1991).

A prolific writer, McCosh was a pastor in Scotland and a professor at Queen’s College, Belfast, before becoming president of the College of New Jersey (now Princeton University). In The Intuitions of the Mind (1860) he argued that while acts of intelligence begin with immediate knowledge of the self or of external objects, they also exhibit intuitions in the spontaneous formation of self-evident convictions about objects. In opposition to Kant and Hamilton, McCosh treated intuitions not as forms imposed by minds on objects, but as inductively ascertainable rules that minds follow in forming convictions after perceiving objects. In his Examination of Mr. J. S. Mill’s Philosophy (1866) McCosh criticized Mill for denying the existence of intuitions while assuming their operation. In The Religious Aspects of Evolution (1885) McCosh defended the design argument by equating Darwin’s chance variations with supernatural design. J.W.A.
