Hamlet Essay: The theme and the quote

Quote:
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 god-like reason
To fust in us unused

     Any man can be at a disposition at any case that concerns his feelings of the past and the unjust events that are going to happen in the future. Hamlet has accounted for such experiences that he was at the brink of meeting his revenge without further hesitation. But as Hamlet looks back at the plans and schemes he's contrived, there was no other alternative than to see eye for eye with the one killer he calls king. "What is a man, if his chief good and market of his time be but to sleep and feed?" is the basic necessity of standard living that Shakespeare emphasizes when talking about all the things Hamlet thought was just normal. Hamlet realized that it's not that simple to be a man, hence asking the question and specifically claiming the right that people deserve to be man when they think they're up to any task. Shakespeare takes on the tone and theme of man and his powers that revel his actions.
     Hamlet began to say the quote/beginning of the soliloquy of Act 4 when encountering Fortinbras's soldiers and captain. To say the least, the quote signifies man's decisions on the type of output he conceives is righteous. What the quote brings about to the tone of Hamlet is that a explanation of what life may be is actually misleading and can often lead to a tragic ending. Shakespeare ties in a satirical momentum for all characters of the play who realize that their powers are so limited that any outcome they desire is mistaken to believe in. Almost everyone in the play have made up their minds to a certain point, but the only one met outside the thinking of factual decisions is Hamlet. Thoughts and thoughts build up in Hamlet; making him a dynamic character who can't understand himself until brought to deductive reasoning. The quote manages to put Hamlet in a position to be a man, to be human who struggles at the most critical points. [In continuum]
