SATAN: he is described by Milton as an epic hero and he is the symbol of rebellion against authority. He is a great and fair leader and a great speaker. He tells his followers the truth, he is not sugarcoating it, he explains what they are losing to gain freedom and that is why he is fair. He is willing to lose everything, to leave Heaven for the sake of freedom. The power of speech he owns is the sign that he is as powerful as God. But, as the poem goes on, we won't see him as the hero anymore, because he will be blinded by his thirst of power and ambition and his self-confidence will border with arrogance. His appearance will also change and he will become a monster because he is moved by vengeance. The change in aspect is directly connected to the morality.
This quote from "Satan's speech" means that the mind is a powerful tool and the best weapon to ever exist. It can make us create what we want out of the things that surround us and it has no limits.
"A mind not to be chang'd by Place or Time".
AMBITION: it can be considered as an element of foreboding/foreshadowing. It is indeed his ambition to reign that will mislead him and thus he is doomed.
We can say that, in a certain way, Satan is similar to Macbeth. As a matter of fact they both are powerful and blinded by ambition.
Macbeth is a strong knight who, after the prophecy of the three witches, will do anything in order to be king and to keep the throne, but his thirst of power will get him killed.
Adam and Eve: "The Just-Created Adam".
When Adam is created he immediately starts looking around, gazing upon all the things that surround him, just like a baby. He starts wondering about the origins of life, reflecting upon our role on this planet and he search for answers in all the creatures that surround him because only nature knows his origins. Adam is just like a child that keeps wondering because he has not met the worst part of the world yet, he does not know about death and that makes him invincible. When we are old it seems our only concern is death, but when we are young we do not worry and we are free to wonder, we are invincible.
Like Adam even nowadays we search for our roots, our past, we investigate our origins because we were not born in the void but we all have connections and we want to find them because maybe they will give a sense to our lives.
Robinson Crusoe belongs to the middle-class, which is referred to be the best among the other classes because it is not exposed to misery and hardship and it is not full of luxury, pride and ambition. Crusoe is the so called middle-class hero, with his will of traveling and searching for his own identity, and a self-made man. He is predestined to do great things because he is the only survivor and he follows the Bible and so through his adventures he will prove to be worth of salvation. He keeps a journal of his experience to see and understand God's will. On the island nature will be his enemy and he will win using a rational approach, he will demonstrate to be a coloniser by rendering the island the epitomy of England, he recreates an organized primitive empire.
