My knowledge extends only to what I know. I know upon finishing this poem I will get up from my desk, turn off the lamp and see the growing light of the greater light spreading across the porch making the things of this world distinct. Later, I will step out into that light satisfied that the structures of the world are in place to make it go around one more day, or at least for the time it takes me to drive to work, place the lunch I made the previous night on the break room counter and sit down at my desk. But first I know I will finish this poem.
