Which theme is reinforced in the excerpt below from Shakespeare's Hamlet?


Rightly to be great

Is not to stir without great argument,

When honor's at the stake. How stand I, then,

That have a father kill'd, a mother stain'd,

Excitements of my reason and my blood,

And let all sleep[?]


>>appearance versus reality


>>complexity of action
