Since art often depicts functional purposes and sometimes has no function other than to convey or communicate an idea, then how best to define the term "art" is a subject of constant contention; many books and journal articles have been published arguing over even the basics of what we mean by the term "art".
Theodor Adorno claimed in his
Aesthetic Theory (1969), "It is self-evident that nothing concerning art is self-evident." Artists, philosophers, anthropologists, psychologists, and programmers all use the notion of art in their respective fields and give it operational definitions that vary considerably. Furthermore, it is clear that even the basic meaning of the term "art" has changed several times over the centuries, and has continued to evolve during the 20th century as well. The main recent sense of the word "art" is roughly as an abbreviation for "
fine art". Here we mean that skill is being used to express the artist's creativity, engage the audience's aesthetic sensibilities, or draw the audience toward consideration of the "finer" things. Often, if the skill is being used in a functional object, people will consider it a
craft instead of art, a suggestion that is highly disputed by many
contemporary craft thinkers. Likewise, if the skill is being used in a commercial or industrial way, it may be considered design instead of art, or contrariwise, these may be defended as art forms, perhaps called
applied art. Some thinkers, for instance, have argued that the difference between fine art and applied art has more to do with the actual function of the object than any clear definitional difference. Even as late as 1912, it was normal in the West to assume that all art aims at beauty, and thus that anything that was not trying to be beautiful could not count as art. The
cubists,
dadaists,
Stravinsky, and many later
art movements struggled against this conception that beauty was central to the definition of art, with such success that, according to
Danto, "Beauty had disappeared not only from the advanced art of the 1960s but from the advanced philosophy of art of that decade as well." Another view, as important to the philosophy of art as "beauty", is that of the "sublime", elaborated upon in the twentieth century by the
postmodern philosopher
Jean-François Lyotard. A further approach, elaborated by André Malraux in works such as
The Voices of Silence, is that art is fundamentally a response to a metaphysical question ("Art", he writes, "is an 'anti-destiny'"). Malraux argues that, while art has sometimes been oriented toward beauty and the sublime (principally in post-Renaissance European art), these qualities, as the wider history of art demonstrates, are by no means essential to it. Perhaps (as in Kennick's theory) no definition of art is possible anymore. Perhaps art should be thought of as a cluster of related concepts in a
Wittgensteinian fashion (as in
Weitz or
Beuys). Another approach is to say that "art" is basically a sociological category, that whatever art schools, museums, and artists define as art is considered art regardless of formal definitions. This "institutional definition of art" (see also
Institutional Critique) has been championed by
George Dickie. Most people did not consider the depiction of a store-bought
urinal or
Brillo Box to be art until
Marcel Duchamp and
Andy Warhol (respectively) placed them in the context of art (i.e., the
art gallery), which then provided the association of these objects with the associations that define art. Proceduralists often suggest that it is the process by which a work of art is created or viewed that makes it art, not any inherent feature of an object, or how well received it is by the institutions of the art world after its introduction to society at large. If a poet writes down several lines, intending them as a poem, the very procedure by which it is written makes it a poem. Whereas if a journalist writes exactly the same set of words, intending them as shorthand notes to help him write a longer article later, these would not be a poem.
Leo Tolstoy, on the other hand, claims in his
What is art? (1897) that what decides whether something is art is how it is experienced by its audience, not by the intention of its creator. Functionalists like
Monroe Beardsley argue that whether a piece counts as art depends on what function it plays in a particular context; the same Greek vase may play a nonartistic function in one context (carrying wine) and an artistic function in another context (helping us appreciate the beauty of the human figure). Marxist attempts to define art focus on its place in the mode of production, such as in
Walter Benjamin's essay
The Author as Producer, and/or its political role in class struggle. Revising some concepts of the Marxist philosopher
Louis Althusser,
Gary Tedman defines art in terms of social reproduction of the relations of production on the aesthetic level. ==What should art be like?==
