“Certainly, it’s a stretch to point to one single work of art as having changed the world. Nor can one point to any one single event or person as having accomplished that. The root of all change is a (grass-roots) movement: monotheism, democracy, industrialization, environmentalism; the list throughout history is immense. All of these have art as an integral part, directly or not, because art is a part of all human endeavors.” – Susan Lucier http://artmutt.blogspot.com

Can Art Change the World?

A Holistic Theory by Jerry Saltz

“In concert with other things, however, art can change the world incrementally and by osmosis. This is because art is part of a universal force. It has no less purpose or meaning than science, religion, philosophy, politics, or any other discipline, and is as much a form of intelligence or knowing as a first kiss, a last goodbye, or an algebraic equation. Art is an energy source that helps make change possible; it sees things in clusters and constellations rather than rigid systems.”

My two cents are:

If an artist admits that “art can change the world” she is aware of her responsibility. She is okay with being held responsible for the message she puts across.
