You picked a rather easy example though.
Yes, I deliberately chose an easy example. The post was really just answering cornsail's request for an example of art communicating something.
Of course this painting is a representation of the effects of the plague and of course it tells a story. But for much of the art that is generally considered to be great, it would be far less straightforward to say what, if anything, is being communicated.
Similarly the case for much of the music that is generally considered great, if we are including music in the broader sense of the word "art".
Yes, I agree, and that's what a different post of mine was trying to say I guess. Some people have no sense of smell. They're aware they're in the minority so they don't think 'smell' is a crock. If
most people couldn't smell, there might be a general attitude that the few people who say roses smell good could actually be full of it.
I have an aspie friend who can't tell if people are happy or sad without asking them the direct question. If that was the normal state of affairs, people who could tell emotions visually might be regarded as making stuff up to look special.
I had a friend in highschool was one of the smartest people I know, but he was unable to do things like detect missing notes in musical phrases. ie: Shave and a haircut, four -space- sounded just fine. His main way to judge a 'good' guitarist was by counting how many notes the person could play in a second. He couldn't detect an emotional quality from bending or syncopating. Shifting up a key didn't sound uplifting. Shifting down a key didn't sound sad. He just didn't have that type of perception.
It's part of the natural distribution of all our sensory capabilities. Some people look at a painting and see 'random splatters of paint'. Some see the artist's success in producing a bright or dark emotional piece, a resting balanced (Raphael's Madonna of the Goldfinch), or an energizing unbalanced (Degas' Singer with the Glove) piece &c.
It's not always a question of intelligence or sophistication. I have that allele that makes cilantro taste like detergent. I can't imagine why I would take it upon myself to decree that people who like cilantro must therefore be a circle jerk of fakers.
Having said that... many artists deliberately include elements that are like easter eggs that people in the know can appreciate. (For example, in the abovementioned Madonna of the Goldfinch, the baby Jesus' arm outstretched is an allusion to preknowledge of his crucifiction... a tweak probably unnoticed by non-Christians) In that sense, there could possibly be a basis for some people feeling like outsiders. But the same goes for any creation. When Chris Hardwick makes a Star Wars joke on @Midnight that only hardcore fans who have read the canonical novels will understand, I don't think it means I should pillory him for his "elitism".
But this is the world we live in. A lot of the time when somebody discovers there's an expertise they're weak on, the response is to decree that the expertise is all a hoax. Creationists do this with evolution. AGW deniers do this with climatology. Holocaust deniers do this with historians. New Agers do this with medicine. (I was at a meeting last night, and I was the only person there who felt there was any value in licensing doctors - news to me but
apparently, they all just buy their degrees for cash and get stoned for four years and call it medical school. I thanked them for letting me in on the big secret.)
