Free Will and Obedience
Milton builds the entire poem around one question: can God be just if He allows humans to fall? His answer is that free will makes obedience meaningful. God doesn't force loyalty. Adam and Eve choose to disobey, and that choice is what makes the Fall real and the punishment fair. The poem keeps testing this logic through Satan, through Eve, through Adam.
Pride and Its Consequences
Satan falls because he can't accept being second. His pride convinces him that rebellion is dignity. But the poem tracks what pride actually produces: Hell, corruption, a body turned into a serpent. Every step Satan takes away from God makes him smaller, not greater. Adam and Eve's desire to be 'like gods' follows the same pattern.
Knowledge and Its Limits
The forbidden tree is the Tree of Knowledge of Good and Evil. Wanting to know more than you're meant to know is what triggers the Fall. Raphael warns Adam not to chase abstract knowledge at the expense of what actually matters. The poem doesn't say knowledge is bad — it says some knowledge comes at a cost humans aren't ready to pay.
Redemption and Grace
The Fall is not the poem's final word. From Book 3 onward, the Son's offer to sacrifice himself for humanity is already in place. Michael's visions in Books 11-12 show Adam that suffering and sin will be answered by grace. Milton frames human history as a long arc that bends toward redemption, even if the path is painful.
Gender, Hierarchy, and Relationship
Adam and Eve's relationship is built on a hierarchy Milton takes seriously: Adam is created first, Eve from Adam's rib. But the poem also shows that hierarchy failing — Adam defers to Eve when he shouldn't, and Eve is left alone when she shouldn't be. Their relationship after the Fall breaks down into blame before it slowly rebuilds into something more honest.
