The philosopher Denis Dutton identified six universal signatures in human aesthetics:
Expertise or virtuosity. Humans cultivate, recognize, and admire technical artistic skills.
Nonutilitarian pleasure. People enjoy art for art's sake, and don't demand that it keep them warm or put food on the table.
Style. Artistic objects and performances satisfy rules of composition that place them in a recognizable style.
Criticism. People make a point of judging, appreciating, and interpreting works of art.
Imitation. With a few important exceptions like abstract painting, works of art simulate experiences of the world.
Special focus. Art is set aside from ordinary life and made a dramatic focus of experience.
It might be objected, however, that there are rather too many exceptions to Dutton's categories. For example, the installations of the contemporary artist Thomas Hirschhorn deliberately eschew technical virtuosity. People can appreciate a Renaissance Madonna for aesthetic reasons, but such objects often had (and sometimes still have) specific devotional functions. "Rules of composition" that might be read into Duchamp's Fountain or John Cage's 4′33″ do not locate the works in a recognizable style (or certainly not a style recognizable at the time of the works' realisation). Moreover, some of Dutton's categories seem too broad: a physicist might entertain hypothetical worlds in his/her imagination in the course of formulating a theory. Another problem is that Dutton's categories seek to universalise traditional European notions of aesthetics and art forgetting that, as André Malraux and others have pointed out, there have been large numbers of cultures in which such ideas (including the idea "art" itself) were non-existent.
