"However - just because I don't like it, doesn't mean to say I don't say it's art. There is art out there that I would define as such - even though I utterly dislike it." Well said. And the converse is also true. Many people mistake what they like/dislike as a judgement of the worth/lack of worth of an artwork, which ain't so. Ultimately, the question with regard to any work is the informed judgement of posterity. You can go back in time to a point where Joachim Raff was considered one of the greatest composers. Now it's "who?". And that assessment is not going to turn round again (though personally I like Raff). And you can find a time when JS Bach was considered a boring mediocrity. Again, that view can never be held again seriously in the future. As to whether in the future the work of Carl Andre and Josep Beuys will still be considered art, or judged an embarassing episode of posturing best forgotten, we wait to see.
