Alright, poetry is created by arranging language in a way that conveys as much conscious experience as possible. In other words, one important dimension of the poetry is that it gives you not only information, but an experience. If it is really good, you are transported into the world of the author. This seems to be true of all art. What makes art different from regular information is its ability to induce an experience. From music, painting, poetry, film, literature etc. people can often pull tangible experiences different then the ones fed to them by the external reality. Art can synthesize touches, tastes, smell, sights, and sounds.
But it is never complete. Although we can get close, we are never truly detached from reality. Our heads may be immersed in the world of the artist, but our feet are still firmly in our world.
Maybe that's because no piece of artwork has ever been good enough to synthesize an entire reality of conscious experience.
Except one. The universe itself.
It's almost as if reality is the best poem ever written, because our immersion in it is TOTAL. It is even written in a language, the language of mathematics. Whenever I do my physics homework, I like to picture the universe in this way: as a divine poem written in the language of mathematics. It is a romantic view, and not at all an invalid one.
If there exists a higher power, he is definitely an artist.
Then again, it seems a little arrogant to say the universe is a piece of art, art being a human creation and humanity existing within the universe. However, what does seem reasonable is to say that instead of the universe being art, art is an imitation of the universe. All the art humanity has ever created is an homage to the most beautiful and divine creation of all: reality.
