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 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 creative art or “fine art.” Here we mean that skill is being used to express the artist’s creativity, or to engage the audience’s aesthetic sensibilities, or to draw the audience towards 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 which 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. Art usually implies no function other than to convey or communicate an idea.
Even as late as 1912 it was normal in the West to assume that all art aims at beauty, and thus that anything that wasn't trying to be beautiful couldn't 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 1960’s but from the advanced philosophy of art of that decade as well." Perhaps some notion like "expression" (in Croce’s theories) or "counter-environment" (in McLuhan’s theory) can replace the previous role of beauty. Brian Massumi brought back "beauty" into consideration together with "expression". 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 towards 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.
