The artist can be seen as an oddball characters like Michelangelo, who lay on his backs for years painting a ceiling. Or Damien Hirst who chops up cows and calls it art. The artist may even go as far as cutting off their own ear as Van Gogh did in the pursuit of creating art.
But artists also have their own vision of the world, they encourage to view the world from a different perspective. They challenge our beliefs, our views, our attitudes and attack our complacency. Artists create works of art which in themselves are worthless, yet we put great value on them. These works are often seen as the pinnacle of human achievement and appeal to our feelings.
