Why do people make art?

At the beginning of last term I asked you to consider several questions:
Who is an artist? What does it mean to be creative? and What does an artist need to be productive and creative?
You wrote very thoughtful responses on your blog. We discussed these ideas in class and you practiced much of what we discussed in the weeks following.

At the beginning of this new term, let's ponder a new and perhaps more difficult question...
Ever since the beginning of time (see below), people have been making pictures, making art...but why?
WHY, DO YOU THINK, DO PEOPLE MAKE ART?
Answer this question as thoughtfully and thoroughly as you can on your blog.
