Plato's banishment of the poets, Aristotle's catharsis, Kant's disinterested judgement, Hegel's end of art, Heidegger on Van Gogh's shoes, Danto on the Brillo Box. Aesthetics from the Republic to the contemporary debate.
The philosophy of art is the philosophical investigation of what art is, what makes something beautiful, what aesthetic experience consists in, and why any of it matters. The discipline is as old as Plato's Republic and as current as last week's debate about whether AI-generated images are art.
The questions recur in different vocabularies. What distinguishes a Brillo box made by Andy Warhol from one made by the Brillo company? What is the difference between a beautiful sunset and a beautiful painting of one? Why does tragedy please us when its content is grief? Is there a fact of the matter about whether a poem is good?
This deck covers the canonical figures (Plato, Aristotle, Kant, Hegel, Heidegger), the 20th-century definitional debates (Bell, Beardsley, Dickie, Danto), and the contemporary aesthetics that has emerged since (Carroll, Levinson, Dutton, the cognitive-evolutionary turn).
Plato's Republic, Book X, contains the founding scandal of Western philosophy of art: the proposal to exclude poets from the ideal city. The argument is sustained, technical, and notorious.
The metaphysical premise: reality has three levels. The Form of the bed (the abstract ideal); the carpenter's bed (a material instance); the painter's bed (an imitation of the carpenter's). Painting is therefore at "third remove from reality" — an imitation of an imitation.
The psychological premise: poetry and drama work on the irrational part of the soul. They produce vivid emotional engagement with characters whose virtues are mixed; they thereby strengthen passions over reason; they corrupt the political community by training its members to indulge feelings rather than govern them.
The political conclusion: the well-ordered city must banish the poets. Hymns to the gods and praises of good men may stay; mimetic poetry — Homer, the tragedians, the comic poets — must go.
Plato is at his most ironic here. He is himself a literary master; the dialogues' force is largely dramatic. Most readers since have understood Book X as a provocation rather than a settled doctrine — a placement of the question of art's value at the centre of political philosophy.
The Phaedrus and the Ion add complications. In the Phaedrus, poetic inspiration (enthousiasmos) is divine madness; the poet does not know what they say. In the Ion, the same poet cannot give a coherent account of why their work is good. Both dialogues frame artistic creation as a power that operates outside rational control — and that the philosopher must therefore engage with carefully.
Aristotle's Poetics (~335 BCE) is the most influential single text in the history of literary theory. It is also a deliberate philosophical answer to Plato.
Where Plato saw poetry as inferior imitation of reality, Aristotle reframed: mimesis is constitutive of human cognition. We learn by imitating; we recognise our world by representing it. The pleasure we take in art is the pleasure of recognition and understanding.
The Poetics's technical claims:
Tragedy is the imitation of an action that is serious, complete, and of a certain magnitude. The famous definition. The action — what happens in the plot — is the most important element. Character serves action. Spectacle is the least important.
The tragic plot has a beginning, middle, and end — a unity that comes from the necessary or probable connection of events. Random sequences of action are not plots.
The tragic hero suffers a reversal (peripeteia) and a recognition (anagnorisis), preferably together. The reversal of fortune comes from a flaw or error (hamartia) — not pure villainy and not simple bad luck.
The tragic effect is catharsis — a "purgation" or "clarification" of pity and fear through their dramatic arousal and resolution. Aristotle's two sentences on catharsis are the most contested passage in the work; the term has been read homeopathically (purging pity by inducing it), morally (educating the emotions), and cognitively (clarifying the conditions under which they apply).
The Poetics's answer to Plato: poetry is not corrupting; it is morally and cognitively formative when well-made. The well-made tragedy trains its audience to feel the right things about the right kinds of action.
Plotinus (~204-270), in the Enneads, refused Plato's banishment. The artist, in Plotinus's framework, does not imitate the material object (the bed); the artist looks past the material toward the Form itself and gives that Form sensible expression.
This is one of the most consequential single moves in the history of aesthetics. It reverses Plato's three-level metaphysics: instead of art being at third remove from reality, the artist works directly from the Form, with the medium serving as a way of making the intelligible visible. The artist becomes a kind of philosopher.
The Plotinian framework filtered through Augustine into Christian theology — beauty as a property of the divine, with earthly beauty as a participation in or reflection of the divine source. Pseudo-Dionysius, Bonaventure, and Aquinas all develop the line. Aquinas's three conditions of beauty (integritas, consonantia, claritas — wholeness, proportion, radiance) are a Plotinian inheritance.
The Renaissance recovers the pagan-Plotinian formulation in Marsilio Ficino, Pico della Mirandola, and the Florentine Neoplatonists. The artist as a kind of seer, expressing the eternal in the temporal, is the Neoplatonic legacy that runs through Michelangelo's Sistine Chapel, Raphael's School of Athens, and the high Renaissance theory of art.
The 19th-century Romantic theorists — Coleridge especially — re-invent versions of the Plotinian theory under the name "imagination." The English-language reader knows the Plotinian tradition through Romanticism's recasting more than directly.
David Hume's 1757 essay "Of the Standard of Taste" is the founding modern attempt to reconcile two facts that seem to pull against each other: aesthetic judgements feel objective (we say a poem is good, not just that we like it) and yet aesthetic disagreement is endemic (people of equal cultivation disagree about which poem is best).
Hume's resolution: there is a standard of taste, but it is constituted by the convergent judgement of qualified critics rather than by any property intrinsic to the artwork. The qualified critic is one who has:
Delicacy of imagination — sensitivity to subtle distinctions in the work.
Practice — extensive engagement with works of the same kind.
Comparison — exposure to a wide range of works enabling comparative judgement.
Freedom from prejudice — independence from local, partisan, or temperamental biases.
Good sense — intelligence, breadth of mind.
The judgement of qualified critics, Hume claimed, will tend to converge over time on the great works. The persistence of Homer, Virgil, and Shakespeare across two thousand years, while contemporary fashions come and go, is the empirical evidence.
The framework's strengths: it accommodates aesthetic disagreement (most disagreement is among insufficiently qualified critics); it explains the canonisation of great works (convergent qualified judgement over time); it preserves the pseudo-objectivity of aesthetic claims without metaphysical commitment to aesthetic properties.
The weaknesses: who counts as a qualified critic is itself contestable; the empirical claim about convergence over time is dubious in detail; the framework risks circularity (the qualified critics are those whose judgements converge with other qualified critics).
Hume's essay remains the standard starting point for any serious treatment of taste — and the position any plausible theory has to either accept or reject.
The Critique of the Power of Judgement (1790) is the founding text of modern aesthetics as a philosophical sub-discipline. Kant's project: to show how judgements of beauty can be subjectively grounded yet make a claim to universal assent.
Kant's analysis of judgements of taste produces four "moments":
The sublime (§23-§29) is the second major topic. Where the beautiful is bounded and harmonious, the sublime is overwhelming — we encounter our cognitive faculties' inadequacy to the object, and the resulting feeling combines pleasure (in our rational vocation that exceeds the sensible) with displeasure (at the failure of imagination).
Kant's framework dominates aesthetics through the 19th century and most of the 20th. The disinterested-pleasure account of beauty, the universal-but-subjective structure of taste, the centrality of the sublime — all are Kantian.
Friedrich Schiller's Letters on the Aesthetic Education of Man (1795) extends Kant's framework into a political-anthropological argument about the role of art in human freedom.
Schiller's diagnosis of modernity (written in the shadow of the French Revolution's terror): the modern human is split between sensuous nature (immediate desire, particular interest) and rational nature (universal moral law, abstract duty). The two faculties operate against each other; both are partial; the integration is failing.
The Greek-classical ideal — the integration of sensibility and reason in the beautiful soul — has been lost to specialisation, division of labour, and the rationalist abstractions of the Enlightenment. The terror of the Revolution showed what happens when reason imposes itself on sensibility without their reconciliation.
The remedy: aesthetic experience. The "play drive" (Spieltrieb) is the third faculty that mediates between sensibility and reason. Engagement with beauty exercises both faculties simultaneously, in their mutual freedom. Aesthetic education — sustained engagement with the beautiful — is the path back to integrated humanity.
Schiller's claim that "man is fully a man only when he plays" became foundational for the German Romantic and Idealist traditions. Hegel, the Schlegels, Goethe, and (much later) Marcuse, Adorno, and the Frankfurt School all develop variants.
The political implication: aesthetic education is the precondition of political freedom. Citizens whose sensibility and reason are integrated are capable of self-governance; citizens whose faculties are split are subjects of either tyranny or chaos.
Schiller's framework reads as quaint to many 21st-century readers, but its underlying structure — that engagement with art has formative effects on the human capacities that political life requires — is taken up by every subsequent argument for arts education, from the Bauhaus to the National Endowment for the Arts to the contemporary humanities-defence literature.
Hegel's Lectures on Aesthetics (delivered 1818-1829, published 1835 from student notes) construct the most ambitious philosophy of art ever attempted. Art, for Hegel, is one of three modes by which Spirit (Geist) becomes conscious of itself — the others being religion and philosophy.
Hegel's tripartite history of art:
Symbolic art (early Egyptian, Indian). Spirit gropes toward sensuous expression but the form remains inadequate to the content. Massive, mysterious, hieroglyphic. The pyramid as the symbolic monument.
Classical art (Greek). Form and content perfectly balanced. The human body becomes the appropriate sensuous form for spiritual content. Greek sculpture is the artistic ideal — the moment in human history when art achieved its full task.
Romantic art (Christian, modern). Content has overflowed form. Spirit has become too rich, too inward, too self-aware to be fully expressed in sensuous medium. Christian painting and modern poetry struggle to contain what they aim at; the medium becomes inadequate again, but inadequate by excess of inwardness rather than insufficiency of grasp.
The famous "end of art" thesis follows from this. Once Spirit becomes self-aware enough that no sensuous form can adequately express it, art ceases to be the vehicle of Spirit's highest self-knowledge. That role passes to religion (in feeling) and ultimately to philosophy (in concept). Art continues to be made, but it is no longer where the deepest cultural-spiritual work is done.
Hegel's claim has been read variously. The strict reading — art is literally finished — is hard to defend; the looser reading — that art has lost the position it held in Greek antiquity as the central organ of cultural self-understanding — is the empirical claim Danto would later inherit and update.
Arthur Schopenhauer's The World as Will and Representation (1818) gives art the highest possible philosophical status — and gives music a unique position even within art.
Schopenhauer's metaphysics: the world has two aspects. As representation, the world is what cognition presents — phenomena in space, time, and causal relation. As will, the world is the blind, restless, suffering striving that lies under all phenomena. The will is what we are when we are not representing.
Most life is suffering because the will is structurally insatiable — desires are satisfied, new desires arise, the cycle is endless. The aesthetic experience offers a temporary release. When we are absorbed in contemplation of a beautiful object — a landscape, a painting, a poem — we momentarily cease to will. We become "the pure subject of knowing," and the suffering of the willing self subsides.
The arts, in Schopenhauer's hierarchy, present the Platonic Ideas — the forms of phenomena that ground perception. Architecture presents the lowest Ideas (gravity, rigidity, weight); landscape painting and animal painting present higher ones; tragic drama presents the human will at its most exposed.
Music is the exception. Music does not represent any Idea; it is "a copy of the will itself." It bypasses the Idea-level and gives sensuous form directly to the metaphysical reality. This is why music affects us so strongly — we are encountering, in aesthetic distance, what we ourselves are.
Schopenhauer's philosophy of music had immense influence on Wagner, who claimed Schopenhauer's framework as the philosophical basis for his music dramas. Through Wagner the framework reached Nietzsche; through both Wagner and Nietzsche it reached the modernist tradition. The 20th-century claim that music is the art form most directly metaphysical is Schopenhauer's.
Friedrich Nietzsche's The Birth of Tragedy (1872) — his first book, written at 27, while still a Wagner partisan — proposes that Greek tragedy emerged from the tension between two artistic-metaphysical principles.
The Apollonian: form, individuation, dream-image, the principle of measure. Apollo is the god of clarity, light, and bounded form. Apollonian art is sculpture and the visual; it gives us the world of distinct objects.
The Dionysian: ecstatic dissolution, the breaking-down of individuation, intoxication, the principle of unity beneath multiplicity. Dionysus is the god of wine, possession, and the chorus. Dionysian art is music; it gives us the world as undifferentiated will.
Greek tragedy, Nietzsche claimed, was the unique cultural moment when these two principles were held in productive tension. The tragic hero (Apollonian individual) is destroyed by forces (Dionysian wholeness) that the chorus articulates and the audience experiences. The catharsis is the audience's momentary participation in the dissolution and reconstitution of the individual self in the larger reality.
The decline of Greek tragedy, in Nietzsche's account, was the work of Socratic rationalism — Euripides admitted reasoning, dialectic, and clear conceptual exposition into the form, and the tragic synthesis dissolved. Western culture has been Socratic ever since: rational, individuated, optimistic, science-driven. The Dionysian side has been suppressed or pathologised.
The book's argument is in part a polemic for Wagner — whose music-drama, Nietzsche claimed, was reviving the Dionysian element. Nietzsche later disowned this enthusiasm; the Apollonian-Dionysian schema, however, has survived and been borrowed by aesthetic theory ever since.
Leo Tolstoy's What is Art? (1898) is the great moralist's frontal attack on the entire Western tradition of aesthetics. The book is bitter, incisive, and almost universally rejected by professional aestheticians for the past century — and worth reading carefully.
Tolstoy's diagnosis: the entire post-Renaissance European tradition of art has lost its way. Art has become a luxury good for the educated classes — Wagner's operas, decadent French poetry, society portraits — produced by professionals for elites and disconnected from the moral life of the people.
His proposed definition: art is the transmission of feeling from one person to another, through external signs deliberately employed. The artist has felt something genuinely; gives that feeling sensuous form; and the audience genuinely receives it. Anything that fails this transmission test is not art.
The criteria for good art:
Sincerity. The artist must have actually felt what they are transmitting.
Universality. The feeling must be one accessible to ordinary humans, not requiring elite training to receive.
Moral content. The feeling must conduce to brotherhood, compassion, religious feeling — Tolstoy's late-Christian moral framework.
The implications were brutal. Wagner — fake. Most of Beethoven's late symphonies — too elite. Even Tolstoy's own Anna Karenina and War and Peace — failed by the test, by their own author. The art Tolstoy approved was peasant song, simple religious ritual, certain folk arts.
The standard objection: Tolstoy's criteria conflate art with moral edification. The position lost. But the underlying questions — for whom is art made; what is the social function of professional art; can art be evaluated independent of its moral effect — keep returning, in the populism debates of every subsequent generation.
Martin Heidegger's 1936 essay "The Origin of the Work of Art" (lectures 1935-36, published in Holzwege 1950) is the most ambitious 20th-century philosophical text on art. Heidegger asks: what is the artwork's being?
The famous opening move: an analysis of Van Gogh's painting of a pair of peasant shoes. Heidegger reads the painting not as depicting shoes (the equipmental analysis) but as making the world of the peasant — toil, soil, harvest, nightfall — present. The artwork lets the equipmental being of the shoes show itself in a way the shoes themselves, while in use, never could.
Heidegger's account develops two key concepts:
The strife of world and earth. Every artwork sets up a "world" — a meaningful context in which entities show up — and at the same time draws on "earth" — the unyielding, sheltering material that always exceeds the world it sustains. The Greek temple discloses the Greek world; the marble it is made of resists exhaustion by that world. The strife is what gives the artwork its being.
Truth as aletheia. Truth is not correspondence between proposition and fact (the standard philosophical view). Truth is the unconcealment of beings, and the artwork is one of the privileged sites where this unconcealment happens. The artwork is true not by saying something accurate but by letting something show.
The essay reads ahistorically as it expands. The Greek temple, Van Gogh's shoes, a Hölderlin poem are all instances of the same structure. Art, for the late Heidegger, is one of the few remaining counter-forces to the technological enframing he diagnosed in his other late writing.
The Van Gogh reading was attacked by Meyer Schapiro in 1968 (the shoes were the painter's, not a peasant's; Heidegger had projected what he wanted to see). The deeper philosophical structure survives the empirical correction.
Theodor W. Adorno's Aesthetic Theory (1970, posthumous and unfinished) is the most demanding aesthetic treatise of the 20th century and the central document of Frankfurt School philosophy of art.
Adorno's framework reads art as the social formation's negation of itself. Authentic modernist art — Schoenberg, Kafka, Beckett, late Mahler — refuses the smooth integration the culture industry produces; its difficulty is not stylistic eccentricity but a registration of the real difficulty of human life under late capitalism.
Two of his central claims:
The autonomy of art. The artwork's value lies precisely in its independence from immediate use. It refuses to be communication, entertainment, or political instrument. This independence is not aestheticist withdrawal but the artwork's mode of social engagement — by refusing to fit into the system, the artwork reveals the system as such.
The dialectic of mimesis and rationality. Art combines mimetic engagement (the body's sympathetic resonance with the world) and rational construction (form, logic, structure). Modernist art holds these in productive tension; both popular culture (pure mimesis without form) and ideological art (pure construction without sympathy) lose what makes art an organ of truth.
Adorno's Philosophy of Modern Music (1949) had elaborated the framework on Schoenberg vs Stravinsky. The Aesthetic Theory generalises across the arts. The book's prose is famously difficult — sentences that perform the resistance to easy assimilation that Adorno is theorising.
The Frankfurt School line on the culture industry (Horkheimer and Adorno's 1944 Dialectic of Enlightenment) has had wider influence than the more demanding Aesthetic Theory. The argument that mass entertainment standardises consciousness for ideological purposes is now part of the general critical vocabulary.
The 20th-century definitional debate begins with Clive Bell's Art (1914). Bell, writing in the Bloomsbury Group's orbit and in the wake of the Post-Impressionist exhibitions in London, proposed that what makes something art is significant form — combinations of lines and colours that produce aesthetic emotion.
The doctrine is unapologetically formalist. The subject matter of a painting is essentially irrelevant. A great painting and a great Persian carpet share the property of significant form; the carpet is no less the proper object of aesthetic attention than the painting.
Bell's framework has obvious circularity (significant form is what produces aesthetic emotion; aesthetic emotion is what we feel in the presence of significant form), and Bell himself acknowledged the difficulty.
The formalist tradition continues through Roger Fry's art criticism, Clement Greenberg's mid-century formalism (the medium-specificity thesis: each art form should pursue what is uniquely possible in its medium — for painting, the flatness of the picture plane), and Michael Fried's "Art and Objecthood" (1967) defence of high modernism against the rising minimalism.
The formalist consensus dissolved in the 1960s under the impact of conceptual art. Artworks like Robert Rauschenberg's Erased de Kooning Drawing (1953), Yves Klein's empty exhibition Le Vide (1958), and especially the Duchampian readymade tradition (the urinal, 1917) made it implausible that significant form could be a necessary condition of art.
Conceptual art, as Sol LeWitt put it in 1967, is "art in which the idea or concept is the most important aspect of the work." The form is incidental; the concept is the artwork. After the 1960s, formalism could be defended as a position but no longer as a definition.
The 1960s and 70s saw a decisive shift away from defining art by intrinsic properties (form, expression, representation) toward defining art by relational properties — by who confers art status and how.
George Dickie's Art and the Aesthetic: An Institutional Analysis (1974) gave the most-discussed version. Dickie's definition (in its mature 1984 form): a work of art is "an artefact of a kind created to be presented to an artworld public."
The artworld is a loose social institution — galleries, museums, critics, curators, collectors, art schools, the pages of Artforum. The institution confers art status by treating something as a candidate for appreciation. The Brillo Box becomes art when Warhol presents it as art and the artworld treats it as such; the supermarket Brillo Box, identical in physical properties, is not art because it has not been so presented and treated.
The strength of the institutional theory: it accommodates the post-Duchampian reality that visually indistinguishable objects can have different ontological statuses depending on context. It explains how new art forms (video, installation, social practice) achieve recognition. It avoids the circularity of formalist definitions.
The weaknesses are sustained. The theory feels evacuative — it tells us how something is recognised as art but not why we should care; it gives the artworld too much authority and seems to make art status arbitrary; it doesn't help us evaluate one work against another.
Dickie's defenders (and Dickie himself) responded that the institutional theory is a classificatory theory — it tells us what counts as art; questions about value and quality are separate. The defence is technically right and dialectically unsatisfying.
The institutional framework has nevertheless become near-universal in the artworld's own self-description. Curators, dealers, and critics speak the institutional theory in everything they do, even when they reject it as philosophy.
Arthur Danto (1924-2013, Columbia, longtime art critic for The Nation) saw Warhol's Brillo Box at the Stable Gallery in 1964 and walked out a different philosopher.
Danto's central question: what differentiates the Warhol Brillo Box from the supermarket Brillo Box, when they are visually indistinguishable? The answer cannot be in the visible properties of the object. It must be in the object's relation to history and theory — the artwork is an "embodied meaning" that requires interpretation against an art-historical background.
His 1964 paper "The Artworld" introduced the term and the framework. His The Transfiguration of the Commonplace (1981) was the systematic philosophical statement. His After the End of Art (1997) drew the historical conclusion.
The "end of art" claim, in Danto's version: with Warhol, art has reached the philosophical realisation that nothing is excluded from being art. There is no longer an internal historical narrative driving art forward — no school, style, or programme that any next generation must continue. Art has become "post-historical."
This is not the death of art-making — Danto explicitly says art continues — but the end of art as a coherent historical project with a directional logic. After 1964, anything goes; the question becomes which artworks are interesting, valuable, or beautiful, but not which ones advance art's historical mission. There is no historical mission left.
The framework has held up remarkably well. The pluralism of post-1980 contemporary art — painting alongside performance, alongside conceptual, alongside relational, alongside digital — confirms Danto's diagnosis. There is no movement; there is just art being made.
Danto's philosophical legacy is the recognition that artworks are essentially about something, that this aboutness requires interpretation, and that interpretation requires the historical and theoretical background of the artworld. The Brillo Box made him say it; he was right.
Nelson Goodman's Languages of Art (1968) is the most rigorous analytic-philosophical treatment of how artworks function. Goodman, a philosopher of science as well as art, treats artworks as symbol systems — formal structures for representing, expressing, and exemplifying.
His central insight: pictures and texts and musical scores all function semantically, but in different ways. A Renaissance painting denotes its subject (the way a word names an object); a piece of music exemplifies certain properties (it is a specimen of certain sounds, structures, moods); a poem may do both.
Goodman's distinction between autographic and allographic arts is widely cited. Autographic arts (painting, sculpture) admit no instances — only originals and forgeries. Allographic arts (music, literature) admit multiple authentic instances of the same work. The score is the work; any correct performance is the work; the music does not have a single "original."
The replacement for the standard "what is art" question, in Goodman: when is art. Something functions as art when it operates as a symbol in particular ways — referring, exemplifying, expressing — rather than as a transparent vehicle of practical communication.
Goodman's framework has been most fruitful in the philosophy of music (Stephen Davies, Jerrold Levinson) and the philosophy of pictorial representation (Richard Wollheim, Dominic Lopes). The technical machinery he developed — density, repleteness, syntactic and semantic finiteness — is now standard in the analytic-aesthetics toolkit.
The framework's strength is precision; its weakness is in capturing what the cognitive contact with art actually feels like. Wollheim's seeing-in account of pictorial perception, developed in dialogue with Goodman, recovers some of the phenomenology that Goodman's symbol-theoretic approach had bracketed.
Noël Carroll (CUNY Graduate Center) is the most prolific contemporary philosopher of art and one of the most measured. Philosophy of Art: A Contemporary Introduction (1999) and Beyond Aesthetics (2001) are his most-read texts.
Carroll's distinctive proposal — the historical narrative theory — defines art neither by intrinsic properties nor by institutional designation but by historical connection. Something is art if it can be situated in a historical narrative connecting it (through repurposing, opposition, extension, or development) to previously-recognised art.
The theory has the advantage of explaining how new art forms are recognised — they get connected to existing art-historical narratives by critics, curators, and the new artists themselves. The theory accommodates the institutional reality without giving the artworld unconstrained authority. It accounts for both continuity and innovation in art history.
Carroll's broader contributions have been in the philosophy of mass art and popular culture. His A Philosophy of Mass Art (1998) defended the philosophical seriousness of films, television, and popular music against the Adorno-Frankfurt-School dismissal. His framework for analysing horror (The Philosophy of Horror, 1990) and the cognitive theory of narrative are widely used.
The contemporary scene is more pluralistic than the canonical history suggests. Active programs include cognitive aesthetics (the empirical study of aesthetic response), evolutionary aesthetics (Denis Dutton, Brian Boyd), feminist and post-colonial aesthetics, philosophy of music, philosophy of film, philosophy of dance, and the recent surge in philosophy of digital and AI art.
The field has lost the canonical-philosopher structure of the 19th century but gained empirical and analytical rigour. The result is a healthy scholarly mess.
Jerrold Levinson (Maryland) has been the most influential American philosopher of music of the past forty years. His Music, Art, and Metaphysics (1990), The Pleasures of Aesthetics (1996), and the four-volume Music in the Moment (1997) develop a sustained framework for aesthetic experience.
Levinson's intentional-historical definition of art: something is art if it was made with the intention of being regarded in the way that art has, in earlier times, been regarded. The definition is recursive — it pushes the question back to earlier art and ultimately to a primordial founding moment that the framework leaves open.
The definition's advantages: it accounts for the manifest fact that art-making is informed by the maker's understanding of art; it accommodates new art forms and avant-garde extensions while requiring some connection to the tradition; it gives the maker's intention a constitutive role without making art entirely subjective.
Levinson's philosophy of music has been particularly consequential. His Music, Art, and Metaphysics develops the case that musical works are indicated structures — abstract structures of sounds that come into existence when a composer indicates them at a particular historical moment. The same sequence of pitches and rhythms is a different work if invented in 1750 vs invented in 1950, because the same sound-structure indicated in different historical contexts is not the same artistic object.
The framework dovetails with Danto's claim that artworks are essentially historical and Goodman's claim that they are essentially symbolic. The synthesis has been the dominant mode of analytic aesthetics since the 1990s.
Levinson's The Pleasures of Aesthetics includes some of the best contemporary essays on humour, music, and the sublime — readable, careful, philosophically serious.
Denis Dutton's The Art Instinct (2009) is the most accessible statement of the evolutionary-aesthetics programme. Dutton (1944-2010, Canterbury, NZ) drew on Darwin's sexual-selection writings and on contemporary evolutionary psychology to propose that art-making is a human universal with evolved psychological foundations.
Dutton identifies twelve cluster features that recur across cultures and historical periods in what we call art:
direct pleasure; skill and virtuosity; style; novelty and creativity; criticism; representation; special focus (set apart from utilitarian context); expressive individuality; emotional saturation; intellectual challenge; tradition and institution; imaginative experience.
The cross-cultural recurrence of these features, Dutton argued, suggests they are not arbitrary cultural conventions but expressions of evolved human psychological dispositions. The art-making instinct is real, has a Darwinian story, and is plausibly continuous with mate-selection behaviours and signaling.
The empirical work in evolutionary aesthetics — Vessel and Starr's neuroscience of aesthetic experience, Brian Boyd's evolutionary literary theory, Ellen Dissanayake's Homo Aestheticus — has accumulated steadily over the past two decades. The findings are real but limited; they explain why humans make art at all (and why universal categories like rhythm, narrative, representation, and skill recur), without explaining why this particular Bach fugue or that particular Rothko canvas is great.
The dispute between evolutionary aesthetics and culturalist aesthetics is mostly a dispute about which question is being asked. Evolutionary aesthetics answers the species-level "why does this exist at all" question; culturalist aesthetics answers the work-level "why is this one good" question.
The two programmes are complementary rather than competing, though their proponents often write as if they were competing.
For most of the 20th century, beauty was philosophically out of fashion. The avant-garde rejected it (the beautiful is bourgeois, complacent, conservative); the analytic tradition treated it as too vague to do work; the politically-engaged criticism treated it as a distraction from social analysis.
The 1990s and 2000s saw a quiet rehabilitation. Elaine Scarry's On Beauty and Being Just (1999) argued that beautiful objects produce a form of attention — full, unselfish, accurate — that is also the kind of attention required by ethical recognition of other people. Beauty is not opposed to justice; beauty trains the perceptual capacity that justice requires.
Roger Scruton's Beauty (2009) made the case from a different (conservative) direction. Beauty is the rational response to a world that calls for our care; the systematic ugliness of much modern art and architecture is a refusal of the world rather than an engagement with it. The book is polemical and not especially philosophically novel, but it placed beauty back into mainstream conversation.
Alexander Nehamas's Only a Promise of Happiness (2007) — explicitly drawing on Stendhal — proposed that beauty is the promise of further engagement, the perception that an object will repay sustained attention. Beauty is not a static property but a relational dynamism; we find something beautiful when it draws us into ongoing relationship.
The contemporary scene includes serious work on the beauty of mathematical proofs (Paul Erdős, James McAllister), the beauty of scientific theories (Frank Wilczek, Sabine Hossenfelder's contrary view), the beauty of natural environments (Allen Carlson's environmental aesthetics), and the beauty of everyday life (Yuriko Saito's Aesthetics of the Familiar, 2017).
The category that 20th-century theory marginalised has, in the 21st century, become respectable again. The honest reading is that beauty was never as secondary as the avant-garde claimed; the rehabilitation is more a recognition than a discovery.
The 2022-25 wave of generative AI — DALL-E, Midjourney, Stable Diffusion, then video models like Sora — produced the most acute philosophy-of-art debate in a generation. The question structure mirrors the Brillo Box puzzle Danto identified: what is the relation between an AI-generated image and a human-made painting that look the same?
The competing positions:
Continuity view. AI image generation is a new tool, like photography or Photoshop. The art-status of the output depends on how it is presented, contextualised, and interpreted — exactly Danto's institutional-historical framework. AI art is art when it is made with art-making intent and engages art-historical context.
Discontinuity view. AI generation lacks the intentional-historical structure that intentional-historical theories of art require. The "artist" did not make the work in the relevant sense; the system did, and the system has no aesthetic intent. What is generated is image-like content but is not art in the sense the tradition has used the term.
Hybrid view. AI-mediated art is art in proportion to the human's contribution to its making — prompt-engineering, curation, post-processing, contextualisation. Pure generation without significant human shaping fails to be art; substantially human-directed generation succeeds.
The legal frame has consequences. The US Copyright Office's 2023 guidance: human authorship is required; AI-only outputs cannot be copyrighted. The 2024 Théâtre D'opéra Spatial case (Jason Allen's Midjourney-prompted work that won a Colorado state-fair art prize) clarified the legal position; the philosophical position remains contested.
The contemporary art market has split into a generative-friendly wing (Refik Anadol's data-paintings; the "AI art" segment of Sotheby's contemporary sales) and a hostile one (the print and traditional-media galleries that explicitly exclude generative work).
The Danto question — what makes the Brillo Box art when the supermarket box isn't — is now the same question with the latest technology in the role of Brillo. The frameworks of philosophy of art have been remarkably durable.
John Dewey's Art as Experience (1934), based on his Harvard William James Lectures of 1931, gives the pragmatist tradition's contribution to aesthetics. The book is among the most-cited 20th-century works in philosophy of art and is consistently underrated in surveys.
Dewey's central reframe: aesthetic experience is not a special category cordoned off from ordinary life. It is the heightened, integrated form of all experience — the kind of experience in which means and ends are unified, where the doing and the undergoing reinforce each other, where the engagement is complete.
The continuity claim has consequences. The aesthetic is present in skilled craft, in well-made meals, in good conversation, in scientific inquiry done well. The fine-art object is not the sole or even paradigmatic locus of aesthetic experience; it is one site among many.
The corollary critique: the museum tradition that treats art as a separate elevated domain detached from life is misconceived. The works themselves were originally made and used as part of integrated practices of religious, civic, and domestic life. The "fine arts museum" is a 19th-century institutional artefact that risks killing what it preserves.
Dewey's framework has had unusual reach. Ellen Dissanayake's evolutionary aesthetics draws on it. Yuriko Saito's aesthetics-of-the-everyday extends it explicitly. The contemporary art-and-craft revaluation, the maker movement, and the food-as-art literature all sit comfortably in the Deweyan tradition.
The framework's weakness, by analytic standards, is its breadth — Dewey's "aesthetic" extends so far that it includes too much. The strength is the same: he identified that the segregation of aesthetic experience to a special domain misdescribes both art and the rest of life.
Pierre Bourdieu (1930-2002) gave the most influential sociological account of art of the 20th century. Distinction (1979) and The Rules of Art (1992) are the central texts.
Bourdieu's argument: aesthetic taste is not a free expression of individual sensibility. It is structured by the agent's position in social space — by class background, education, and the cultural capital accumulated through these. The "naturalness" with which different classes find different objects beautiful is a learned naturalness; the seemingly-spontaneous judgement of taste reproduces social distinctions through its own enactment.
The concept of cultural capital — the set of dispositions, knowledge, and skills that allow one to operate successfully in cultural fields — runs through the framework. Cultural capital is acquired (through family socialisation, schooling, and exposure) and convertible (into social standing, into economic capital, into political influence).
The field of cultural production — the literary field, the art field, the academic field — has its own structure of positions, its own forms of accumulated capital, its own struggles over what counts as legitimate. Avant-garde and established artists, critical and market-oriented galleries, experimental and traditional schools all occupy positions in fields with their own internal logic.
The implication for philosophy of art: the philosophical question "what makes this art" cannot be cleanly separated from the sociological question "how does this thing come to be recognised as art." Dickie's institutional theory has a Bourdieuian shadow — the institution that confers art-status is itself structured by social logics that the institutional theory does not analyse.
Bourdieu's framework has been largely absorbed into art history (T.J. Clark's social art history; the field of new art history) but is less visible in analytic philosophy of art, which tends to treat the questions as separable. The integration is still partial.
Music has always been the philosophy of art's hardest case. Music does not represent in the way painting does, does not say anything in the way literature does, and yet plainly carries content and produces aesthetic experience. The 20th and 21st-century philosophy-of-music literature has tried to articulate what.
The major positions:
Formalism (Eduard Hanslick, 1854; Peter Kivy in the contemporary literature). Music's content is exhausted by its formal-structural properties — pitch relations, rhythm, voice-leading, harmonic motion. Music does not express emotions; it has structural features that we describe in emotional vocabulary because no other vocabulary fits.
Expression theories (Susanne Langer, 1942; Stephen Davies, 1994). Music expresses emotions, but not by being a sign for them. The music has a temporal-dynamic profile that resembles the temporal-dynamic profile of emotional experience; the resemblance is what allows the music to function expressively without representing.
Resemblance / persona theories (Jerrold Levinson, 1990, 1996). Music expresses emotion by inviting the listener to imagine a "persona" whose emotional state is what the music expresses. The expression is mediated by imagined experience.
Mirror-neuron / embodied accounts (recent neuroscientific contributions). Listeners' motor and emotional systems entrain to musical features; the embodied response constitutes the expressive grasp.
The puzzle of negative emotions in music — why we enjoy listening to music that expresses sadness, fear, or grief — runs through the literature. Levinson's "Music and Negative Emotion" (1982) is the canonical contemporary statement; the answer involves the aesthetic distance from real-life consequence and the cognitive engagement with emotional structure rather than emotional content.
The empirical-aesthetics work (Patrick Juslin's affect-induction studies, Vessel-Starr fMRI work) has begun to constrain the philosophical theories. The dispute remains active, but the questions are more empirically tractable than they were thirty years ago.
The paradox of fiction, named by Colin Radford in 1975: how can we be moved by characters and events we know don't exist? Anna Karenina is a fictional construct. Yet readers cry. The standard accounts of emotion require the believed-existence of the emotion's object — fear requires belief in a danger, pity requires belief in a sufferer. Fictional emotion seems to lack the cognitive prerequisite while having the phenomenology.
The major responses:
Quasi-emotion theories (Kendall Walton, Mimesis as Make-Believe, 1990). What we feel about Anna Karenina is not real pity but make-believe pity — a state with the phenomenology and behavioural-disposition profile of pity but without the cognitive commitment to the existence of the object. Walton's framework treats fiction-engagement as a form of structured imagination; the quasi-emotions are a feature of the imaginative game.
Thought theories (Peter Lamarque, Noël Carroll). The cognitive object of fictional emotion is not the believed-existing character but the entertained thought of the character. We pity the thought of Anna's suffering, not the suffering itself, but thoughts can have the kind of vivid presence that triggers the emotion.
Real-emotion theories (Jerrold Levinson, Robert Yanal). Fictional emotions are real emotions with cognitively unusual objects. Carroll's revision: the cognitive object of pity for Anna is not the abstract proposition but the imagined particular — and imagined particulars can produce real emotional response when the imagining is sufficiently engaged.
The neuroscientific work on narrative engagement (Tania Singer, Mar's transportation studies) tends to support real-emotion theories — the brain regions activated during fiction-engagement substantially overlap with those activated by parallel real-life experience. The phenomenological case for quasi-emotions is weaker than it appeared in Walton's original presentation.
The downstream stake: if fiction can produce real emotional engagement, then fiction has the cognitive-emotional formative power that Aristotle attributed to it (the catharsis line) and that Tolstoy's transmission theory presumed. The contemporary discussion of literary ethics, narrative empathy, and the moral effects of fiction (Martha Nussbaum, Wayne Booth, recent empirical work by Mar and Oatley) all sits on this foundation.
An accessible orientation to the major positions: Plato, Aristotle, Kant, the formalists, the institutional theory, and the contemporary debates. A compact entry into the field's vocabulary.
· The End of Art: Arthur Danto's Influential Art Theory — a careful walk-through of Danto's framework, the Brillo Box moment, and what "post-historical art" actually means in Danto's argument. Particularly useful for understanding the institutional-historical synthesis.
· George Dickie, "What Is Art?" — The Artworld — Dickie's institutional theory in clear summary, with the canonical objections and Dickie's own responses.
Read: Aristotle's Poetics first (still the best). Kant's third Critique for the modern foundation; Heidegger's "The Origin of the Work of Art" for the most ambitious 20th-century essay; Danto's Transfiguration of the Commonplace for the post-1964 framework. The serious student adds Goodman's Languages of Art for the technical apparatus and Levinson's The Pleasures of Aesthetics for the contemporary best example of the field practised well.
Volume III, Deck 14. From Plato's banishment of the poets to Danto's Brillo Box, by way of Aristotle's catharsis, Kant's disinterested pleasure, Hegel's end of art, and Heidegger's peasant shoes.
The questions are durable. What is art; what is beauty; why does it matter; who decides. The answers shift; the questions don't. Each generation that takes art seriously has had to give them.
