We have art in order not to die from the truth. Friedrich Nietzsche

With art, you can make up things and design beautiful pieces of art to create you own reality in order to cover up what others may see as the 'ugly truth'. People, even artists, do what they can to look at the world through their own perspective and decide wether they want it to be bad, or good. Therefore, they have the power to put into their art, what they see through their own eyes, and think in their own minds.
