In response to Mary...

Mary asked: "Can there be a mistake in art, which one would have to admit having made? or do the values which change overlook any mistake?"
I'd like to begin answering this question with a quote I once heard: "creativity is allowing yourself to make mistakes; art is knowing which ones to keep." Whether the artist admits his mistales or not, they still exist. Through my own artistic experiences of formal education and creation, I have made my fair share of mistakes. Looking back on some pieces, there are choices that I've made in my artwork that I wish I hadn't because the piece would be better without them. However, there are also mistakes that have lead to greater development and ultimate success. I think that the act of admitting mistakes, whether they result positively or negatively, is part of the artistic process. If an artist cannot own up to making mistakes, he surely isn't going to be able to learn and grow from them. I think artistic "mistakes" are similar to life mistakes; they may hurt you or benefit you, but you will be infinitely richer if you can recognize, admit, and move on from them.
Q: If one person looks at a work of art and thinks its "ugly" or shouldnt be considered art, can it still be considered art? Do the circumstances change if many people think its "ugly"?
