In _Macbeth_, a not dissimilar play, the life violently altered is kept in the strange channel by a succession of violent acts. In _Hamlet_, when Hamlet's merciful wisdom has decided that the life violently altered shall not be wrenched back, his destroying wisdom decides that she shall not be kept in the strange channel. The King, just in his way, seeks to find out if Hamlet be sane. If Hamlet be sane, he must die. His death will secure the King's position. By his death life will be kept in the strange channel. Polonius, the King's agent, learns that Hamlet is sane and something more. Fate demands violence this way if she may not have it in the other. She offers an instant for the doing of her purpose. Hamlet puts the instant by with his baffling swiftness, which strikes on the instant, when the Queen's honour and his own life depend on it. The first bout in this play of the baffling of action falls to Hamlet. The second bout, in which the King's purpose is again baffled, by the sending of the two courtiers to their death in England, also falls to Hamlet. The bloody purpose from outside life and the bloody purpose from within life are both baffled and kept from being by the two extremes so perfectly balanced in the wise nature. Extremes in the Shakespearean system are tragical things. In Shakespeare, the pathway of excess leads, not as with Blake, to the palace of wisdom, but to destruction. The two extremes in Hamlet, of slowness and swiftness, set up in life the counter forces which destroy extremes, so that life, the common thing, may continue to be common. The mercy of Hamlet leaves the King free to plot his death. The swiftness of Hamlet gives to the King a hand and sword to work his will.
