ACT IV, Sc. 4, Lines 34-58: Sum up Hamlet's thinking in lines 34-48

Hamlet. How all occassions do inform against me,

And spur my dull revenge! What is a man

If his chief good and market of his time

Be but to sleep and feed? A beast, no more.

Sure he that made us with such large discourse,

Looking before and after, gave us not

That capability and godlike reason

To fust in us unused. Now whether it be

Bestial oblivion, or some craven scruple

Of thinking too precisely on th'event -

A thought which, quartered, hath but one part wisdome

And never three parts coward - I do not know

Why yet I live to this thing's to do,

Sith I have cause, and will, and strength, and means

To do't.
