What does Satan reveal about himself in his speeches in book 1 of paradise lost

Through his speeches, Satan reveals that he is not only envious of the position which God holds, but also generally unable to comprehend how this power is retained. The epic form of the poem is undermined by this fact in that the protagonist, which as the only character with any real development so far is necessarily Satan, is defeated by a divine force which he never had a realistic chance of beating. In this was Satan is opposite to the classical epic hero who, through sheer force or intelligence, overcomes the adverse pantheon of Gods to achieve greatness. In this way Satan reveals to the reader that, rather than the epic figure that he should theoretically be, he is more of a tragic figure consistently defeated by himself. By placing Satan as a tragic figure Milton precludes him from being the hero of this epic tale, allowing him room to further his puritanical views of the glory of Christ in that he concludes that the true hero of this poem is Christ who sacrificed himself to cure the original sin wrought by the tragic Satan
In many ways, Satan’s defining feature thus far has been his envy of the power which God is able to wield. Satan constantly compares himself and his own position to that of his creator, and through these comparisons his envy and vitriol shines through. Satan declares hell to be ‘this unhappy mansion,’ which is a biblical reference to Christs declaration that ‘my fathers house has many mansions.’ In this way Satan directly compares his own position to the divine position of heaven and the term ‘unhappy’ adds a biting sarcasm to this comparison which underlines his envy. Satan seems entirely fixated on the fall he has experienced, his lexical field ‘hail, horrors hail,’ begins to phonetically mirror the word hell, with the repeated ‘H’ sound and the word ‘hail’ literally sounding like the word hell. Even in his later speech Satan seems transfixed on this disparity between himself and god, being unable to accept the fact that he is no longer a ‘celestial spirit.’ His envious nature Is again shown in his fixation on war. Milton ends the speech with ‘ war, then, war,’ which, due mostly to the internal parallelism, is felt by the audience to be an incredibly powerful piece of rhetoric. The use then of this rhetoric to show Satan’s single-minded attitude towards deposing of God serves only to highlight his envy. Satan attempts in vain to elevate himself to a godlike level through the use of the power of the mind but is entirely unsuccessful. Satan declares that ‘the mind is its own place,’ and that it is ‘not to be changed by place or time,’ this is an entirely nonsensical argument, just as Marlowe’s Mephistopheles is forever bound to his eternal damnation, Milton’s Satan is to his. Again we see the use of parallelism ‘make a heaven of hell, a hell of heaven,’ in the context of Satan’s grand rhetorical ability used only to try and elevate his own position and undermine that of Gods, each time Satan uses the great silver tongue, a gift that in Milton’s view would have necessarily been bestowed on him by God, it is as a result of his envy of the position that God holds and he can never quite reach. In this way Satan reveals to he reader just how envious he is of the divine spirit, so envious that he channels the entirety of his greatest gift into vain attempts to reduce the disparity.
