Macbeth is contending with the realities of this world, Hamlet with those of the next.

As long as man labors for a physical existence, though an act of necessity almost, he is yet natural; it is life, though that of this world, for which he instinctively works.

From the wrestling of his own soul with the great enemy, comes that depth and mystery which startles us in Hamlet.

We feel unsatisfied until we know ourselves akin even with that greatness which made the spots on which it rested hallowed; and until, by our own lives, and by converse with the thoughts they have bequeathed us, we feel that union and relationship of the spirit which we seek.

Macbeth is contending with the realities of this world, Hamlet with those of the next.
