Opposites abound in Paradise Lost, including Heaven and Hell, God and Satan, and good and evil. Milton’s uses imagery of light and darkness to express all of these opposites. Angels are physically described in terms of light, whereas devils are generally described by their shadowy darkness. Milton also uses light to symbolize God and God’s grace. In his invocation in Book III, Milton asks that he be filled with this light so he can tell his divine story accurately and persuasively. While the absence of light in Hell and in Satan himself represents the absence of God and his grace.
Milton divides the universe into four major regions: glorious Heaven, dreadful Hell, confusing Chaos, and a young and vulnerable Earth in between. The opening scenes that take place in Hell give the reader immediate context as to Satan’s plot against God and humankind. The intermediate scenes in Heaven, in which God tells the angels of his plans, provide a philosophical and theological context for the story. Then, with these established settings of good and evil, light and dark, much of the action occurs in between on Earth. The powers of good and evil work against each other on this new battlefield of Earth. Satan fights God by tempting Adam and Eve, while God shows his love and mercy through the Son’s punishment of Adam and Eve.
Milton believes that any other information concerning the geography of the universe is unimportant. Milton acknowledges both the possibility that the sun revolves around the Earth and that the Earth revolves around the sun, without coming down on one side or the other. Raphael asserts that it does not matter which revolves around which, demonstrating that Milton’s cosmology is based on the religious message he wants to convey, rather than on the findings of contemporaneous science or astronomy.
One common objection raised by readers of Paradise Lost is that the poem contains relatively little action. Milton sought to divert the reader’s attention from heroic battles and place it on the conversations and contemplations of his characters. Conversations comprise almost five complete books of Paradise Lost, close to half of the text. Milton’s narrative emphasis on conversation conveys the importance he attached to conversation and contemplation, two pursuits that he believed were of fundamental importance for a moral person. As with Adam and Raphael, and again with Adam and Michael, the sharing of ideas allows two people to share and spread God’s message. Likewise, pondering God and his grace allows a person to become closer to God and more obedient. Adam constantly contemplates God before the fall, whereas Satan contemplates only himself. After the fall, Adam and Eve must learn to maintain their conversation and contemplation if they hope to make their own happiness outside of Paradise.
