Hamlet always talks about what should be done or what needs to be done and somehow manages to do nothing.  Once again one gets a speech from Hamlet about action, yet he is acted upon by the king and walks off to England.
How all occasions do inform against me
And spur my dull revenge!

   He watched a actor tear with emotion performing a scene he(the actor) knew personally not, he now sees a army marching to war for land and honor.  His fathers Ghost has come again to wet his blunted purpose.  Hamlet still retreats from action and fails to act in spite of all these blaring occasions.

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 unus'd.  

   Archaically discourse means the ability to reason or the reasoning process (dictionary.com).  Hamlet is stating that the creator has given to each a great ability to think and reason--Godlike even.  Yet the creator gave it not to us to get old and musty unused. One is to reason, come to a conclusion, and then act.

Now, whether it be
Bestial oblivion, or some craven scruple
Of thinking too precisely on th' event,-
A thought which, quarter'd, hath but one part wisdom And ever three parts coward,- I do not know

  Here Hamlet fleshes out his flaw stating wither its some inhuman forgetting or timid moral, it's thinking too precisely on the event.  He is over thinking the matter.

Witness this army of such mass and charge,
Led by a delicate and tender prince,
Whose spirit, with divine ambition puff'd,
Makes mouths at the invisible event,
Exposing what is mortal and unsure
To all that fortune, death, and danger dare,
Even for an eggshell. Rightly to be great
Is not to stir without great argument,
But greatly to find quarrel in a straw When honour's at the stake.

   He gives example of the occasion to spur his revenge.  These men stand strong and bold with bright strong spirits because of there ambition.  They go to war for an eggshell or in other words nothing, yet he says when it comes to honor even straw is worth quarreling over. 

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

  Hamlet states his motivation relative to the princes--His father and mother, yet he lets all sleep while the arm marches.  He dose nothing.

while to my shame I see
The imminent death of twenty thousand men
That for a fantasy and trick of fame
Go to their graves like beds, fight for a plot
Whereon the numbers cannot try the cause,
Which is not tomb enough and continent
To hide the slain? O, from this time forth,
My thoughts be bloody, or be nothing worth! 

  Once again Hamlet swears to his mission of killing the king.

That was an attempt at translating Shakespeare.  However i think what makes this such a remarkable soliloquy is that it puts blood in Hamlets character it gives his soul flesh and bone and his form breath.  We can see that his character is real--one can it feel rather.   Ones own life is but a series of events and choices that are influenced by our thoughts and others actions.  Here Hamlet has been spurred to action by his fathers ghost to kill Claudius, yet this act doesn't appear to be in his nature.  His is a school boy, no athlete, no gladiator.  So how dose he react to the charge, he tries to study the situation out to fuel his thoughts into action.  Indeed every thought he has is on this quest and how natural to turn every situation back to his haunting, bloody mission.  He sees an army 'off to war' and of course his disposition goes to the deed he has yet to perform.  He has been drafted and yet to report.  He sees those who have reported as honored men, proud and ambitions, what he currently feels he is lacking.  Then he turns the plot back to himself trying to incorporate what he has learned: My thoughts be bloody, or be nothing worth! Yet still it is interesting to note the term thoughts...he is still struggling falling short of action.  Just like a human!!
