"The word fantasy remains ambiguous, standing between the false, the foolish, the delusory, the shallows of the mind, and the mind's deep connection with the real.  On this threshold it sometimes faces one way, masked and costumed, frivolous, an escapist; then it turns, and we glimpse as it turns the face of an angel, bright truthful messenger..."
