Over the winter, I was at the
Wexner Center for the Arts in Columbus, which is a modern art gallery. The main exhibit was some pathfinder of the modern art movement from the late 50's. The stuff was large bands of colors on canvas. I was there with my 7 nieces and nephews 3-12 in age. They were being a bit rambunctious in what we thought was an unused waiting area (The Wexner Center itself is a god-awful modernist piece of crap that has none of the traditional cues about where you are or what's important).
Anyway, the guard cautioned us to settle the kids down while around the art master's work, pointing to the stripes of paint on the wall. The kids immediately stopped horsing around and stared at the wall. "That's the art?", they asked in a very disappointed way. So, for them, the emotion was disapointment, so I guess it was art.
More often, the emotion artist try to evoke nowadays is disgust. Unfortunately, oftentimes these artists become architects and instead of being confined in a modern art museum (where at least you are forewarned) they impose their disgusting works on whole populations for fairly long periods of time.
It all seems based on a scam whereby they somehow create a reputation as a visionary and con the municipal authorities into thinking they are priviledged to have them desecrate their town with some disgustingly hideous, or sometimes just extremely boring or oppressive building.
Keep in in the modern art museum and it's OK, this too shall pass.
