momentary stay against confusion

The figure a poem makes. It begins in delight and ends in wisdom. The figure is the same as for love. No one can really hold that the ecstasy should be static and stand still in one place. It begins in delight, it inclines to the impulse, it assumes direction with the first line laid down, it runs a course of lucky events, and ends in a clarification of life—not necessarily a great clarification, such as sects and cults are founded on, but in a momentary stay against confusion. It has denouement. It has an outcome that though unforeseen was predestined from the first image of the original mood—and indeed from the very mood. It is but a trick poem and no poem at all if the best of it was thought of first and saved for the last. It finds its own name as it goes and discovers the best waiting for it in some final phrase at once wise and sad—the happy-sad blend of the drinking song.
