If we focus on the "history" part, I can figure out the answer because I personally think that art is a great resource for us to think about history and society: how people thought, behaved, and responded to their time and social changes.
I am now taking this art history seminar about American Gilded Age. Unlike some of my other art history classes, the reading assignments of this seminar are works reflecting the society at that time (instead of art theories): novels by Charlotte Perkins Gilman, Jack London, Stephen Crane, Horatio Alger, Jr., Jacob Riis' How the Other Half Lives, etc. Different social phenomena that are of particular significance are discussed, such as Masculinity, Nervousness, New Women, Child Labor, etc. Last Wednesday we even had a little "mock trial of Thomas Eakins" in which students got to know the characters and the backgrounds that "caused" thoughts and opinions of the characters. In such way, art history becomes part of "sociology" or "history" discipline where art doesn't really speak for its aesthetic and decorative value, but for its social and historical value.
I love that.
However, some of my other art history classes are mostly about movements within the "art world." They are more into "art and its trend," focusing on "the history of art"—which is the most traditional explanation of the discipline. Of course there are great portion about the society, but the emphasis is on art itself.
Art cannot stand alone. It could be decorative and beautiful, and truly everyone loves "good-looking things" and art can absolutely be the representative of visual pleasure. However, art can be more than that. It can bring inspirations through its various media, subject matters, etc. Art is not limited and therefore, can stimulate people's minds to think more creatively and deeply. Art can draw people's attention to certain social phenomena and art itself is also a kind of social phenomena, leaving people an enormous space to reflect.
Art, at first is part of the history and society—an "artifact", and then is "art".
PS. I love this sofa!!!
