Art is not supposed to change the world, to change practical things, but to change perceptions. Art can change the way we see the world. Art can create an analogy.

Additional Information: This quote by French street artist JR means that art does not transform society in a direct way; rather, it changes society by changing how people view things, by changing how people think about the world around them. Art does not make a straightforward statement but can serve as a powerful symbolic gesture. The quote is from the 2011 TED Prize winner's TED Talk about his artworks and the importance he places on art. Watch the full TED Talk here: JR - My Wish: Use Art to Turn the World Inside Out
