When William Blake wrote "to see a World in a Grain of Sand," he tapped into poetry's power to model the universe. For instance, once we set up a simile between "world" and "grain of sand", we can test this hypothesis of sameness. How is sand like the world? Where will the model fail? And what might that tell us? Imagery, sensory language, arguments, ideas, and verse form itself can lead poetry toward power and discovery. This pursuit can reach from the page into one's own life. We will work hard together on poems, our own and one another's.
