With Hamlet, Shakespeare found that if he refused to provide himself or his audience with a familiar, comforting rationale that seems to make it all make sense, he could get to something immeasurably deeper. The key is not simply the creation of opacity, for by itself that would only create a baffling or incoherent play. Rather, Shakespeare came increasingly to rely on the inward logic, the poetic coherence that his genius and his immensely hard work had long enabled him to confer on his plays. Tearing away the structure of superficial meanings, he fashioned an inner structure through the resonant echoing of key terms, the subtle development of images, the brilliant orchestration of scenes, the complex unfolding of ideas, the intertwining of parallel plots, the uncovering of psychological obsessions.
