#QuoteOfTheMoment: Woody Allen
That's all easy enough to attribute to a character in a movie, and one could make a case for that -- that the job of the artist is to show why life, despite all its horror and brutality, is worth living and is a valuable thing. But one could also take the position that there is no job of the artist.
The artist does what the artist does. If you make a comic movie like Duck Soup, then you're an artist there. If you paint a pretty picture of apples in a bowl like Cezanne does, you're an artist there, and it's not the job of the artist to do anything at all -- just to make the best art that he can, because art gives pleasure and pleasure gives distraction, and distraction is the only thing that gets us by, really.
