Order and disorder is the major theme. This poem uses the opposing concepts of order and disorder to show the two sides of human nature. The orderly side appreciates logic and reason, while the disorderly side is driven by intuition. As Gregg p. uts it, humans require both, but in different ways, which she likens to the twin drives of hunger and thirst. Allowing the desire for order to take over would be counter-productive because only the mind can find and appreciate order, but the world does not exist in the mind.
