In unseen and unacknowledged specter, an “X,” attends at every economic feast, and stands at the elbow of every modern wiseacre. It confounds the forecaster with seeming malice showing itself only in the event and even then with impish and uncertain effect. It laughs at pretensions to knowledge; it tantalizes all figurers, haunts all generalizers and keeps itself to itself, a shadow, an unknown. But phantom as it is, it is still a force, a potent, active, generative substance, mysterious in genesis, related to a dream, but able to accomplish miracles of reality. For the purpose here it will be called the creative experience.
