deciding on important art

People’s opinion in judging a particular artwork is often relative. However, most of the time, people agree on the importance of a certain artworks. Especially curators, who are often educated and have the ability to judge the value of artworks. Although people may have different tastes in picking their favorite artworks; the style, composition, texture, use of color, light and lines and so on all contribute to, and to a degree, determine the quality of an artwork. Using art elements and principles, curators might not be able to determine or agree on the best piece of artwork, but they can definitely determine what's a good/important piece. Thus, these curators are using what they learned from (possibly) school as their source. They are relying on authority as a way of knowing. Also, the importance of an artwork might not mean only the quality of this artwork, it can also suggest historical significance and so on. Curators also need to use their logic to decide on important art. A great piece of art may strike anyone as important. Like everyone else, curators can often rely on their common sense and intuition as sources. But most importantly, curators need previous education and knowledge about art, including art principles, history, to judge and to serve as a way of knowing.
