We can understand art as a process of bringing something into the world that was not there before, it can be an artifact but it can also be an idea. That process, Professor Elaine Scarry calls a fragment of world alteration, and so if we can alter the world in fragments, she says, "just think what can be imagined together, what might be possible in community: a total reinvention of the world."
Every person has a share in this world and a share in the world to come. We understand the concept of a share in the world to come, but what does it mean having a share in this world? Open your hearts. Having a share in this world means I know exactly what I have to do in this world. This is a very high level. If I know that if I don't do it, it just won't happen. Then I've just got to do it. This is my share in this world.
