| Mm. Possibly, but not necessarily. I have a suspicion that art is to humans as fancy tails are to peacocks: the difficulty is the point. I believe this is why we have art galleries proudly displaying oil paintings of fruit bowls, but don't do this for random food snapshots. It's also why photographs as a category were initially dismissed (in an era that had come to praise extreme realism in paintings), but when photographers went on long trips to visit unusual places, people, and events, those photographs suddenly did count as art. Bit of overlap between arts and knowledge shown by the wiktionary entry for the Latin "ars", so this can be extended to the way Socrates didn't like writing, and the desire for hand-made foods and durable goods over mass produced foods and products. https://en.wikipedia.org/wiki/Veblen_good |
We also have them for social/historical reasons. A museum usually isn't built around "best stuff humanity has to offer", but has some sort of more complicated angle.
Eg, a reason why you may have a fruit bowl hanging on the wall is that this particular artist has been influential, and they just happened to paint a fruit bowl. Maybe thousands of artists of the era painted fruit bowls, and maybe a dozen of those are technically more impressive, but this is the guy that got talked about a lot, or started a movement, or such, so it's this guy's bowl we're going to go with.
Museums can have many themes. They may showcase a particular artist, a particular movement, a particular theme, a particular period in time. You can build a museum of nothing but paintings of cats if you wanted to.
