I found this article entitled Art makes You Smart, on the New York Times website. It is written by Brian Kisida, Jay P. Greene and Daniel H. Bowen, and discusses how art can challenge us with a different perspective on the human condition.
I think this underlines why we need more art and creative pursuits in schools. I was shocked, when I found out that often in schools, art is something that they only fit in if they have time. Really our education system needs to step up in so many ways.
