So, show a piece to someone without an art education, and if they think it is interesting it’s classical art, and if they think it is wtf then it’s modern art, nothing to do with when it was made or the definitions of those terms today? This still seems to me like you have redefined modern and classical as interesting and not interesting art you like. Modern art is something specific: https://en.m.wikipedia.org/wiki/Modern_art https://en.m.wikipedia.org/wiki/Modern_art. I would be surprised if you could really show a Van Gogh to someone without an art education, and without explaining the context, and they wouldn’t say it was interesting. Or any of the other art on that page. If you’re just saying in the end modern and classical art don’t exist as defined concepts except by showing individual pieces to people without art educations who are then qualified to sort them into modern or classical categories based on whether they find them interesting or wtf then fine, I don’t really agree but now I see what you’re saying. But if you think all modern art on that page would be found uninteresting by anyone without an art education I’d encourage you to do your experiment and I think you’d be surprised.
