People an feel different emotions when looking at paintings and works of art. These feelings can be used by that persons subconscious to inspire them to do something. e.g. a person may look at a sculpture of a child begging in the street which may inspire them to spend some of their life looking after the homeless or they may see a painting of a cute puppy which may inspire them to buy a dog! Hope this helps and hope its what you meant by the question! :)
