by definition without rule

Although Chaos can be studied in terms of antecedents in classical literature and philosophy, its appearance in [Paradise Lost] owes its problematic character to Milton's theology. Chaos is infinite, and filled by a ubiquitous God who has nonetheless withdrawn his creative will from chaotic matter (7.168-73). None of the categorical binaries established during the creation of Genesis inhere in Chaos. It is neither this nor that, "neither sea, nor shore, nor air, nor fire,/ But all these in their pregnant cause mixed/ Confus'dly" (2.912-14); therefore Satan, as he traverses this indeterminate space, confusedly mixes locomotions, "And swims or sinks, or wades, or creeps, or flies" (2.950). The "embryon atoms" (2.900) of Chaos are "the womb of Nature" (2.911), the pure potential that the Son first circumscribes with golden compasses when creating our universe (7.225-31) and will doubtless use again in creating new worlds (2.915-16). Chaos cannot be good until God has infused it with creative order. It is at least morally neutral, at best thoroughly praiseworthy, as a part of the process by which God makes and sustains all things.
  But alongside the language of atomism, Milton gives us a mythic Chaos, personified as the ruler of his realm, or rather its "Anarch" (2.988), since Chaos is by definition without rule. This Chaos, speaking for his consort, Night, and for a shadowy pack of Hesiodic creatures and personifications (2.963-67), expresses his resentment over recent losses (the creations of Hell and our universe) and supports Satan's mission on the assumption that "Havoc and spoil and ruin are my gain" (2.1009). We thus arrive at a paradox. Theologically, Chaos is neutral or better. Mythically, in terms of the epic narrative, Chaos is the ally of Satan.

Oh humans

Yet God remained whole like a wheel ... Now this wheel is somewhere, and is full of something. For if the wheel had nothing but an outer rim, it would be empty. And if perchance an outsider came and wanted to work there, this cannot be, for two craftsmen cannot exercise their craft in one and the same wheel. Oh humans, look at the human being! For it contains heaven and earth and other creatures in itself, and is one form, and all things hide in it.
  This is what fatherhood is like. In what way? The round of the wheel is fatherhood, the fullness of the wheel is divinity. All things are in it and all stem from it, and beyond it there is no creator. Lucifer, however, is not whole, but divided in dispersion, since he wanted to be what he should not. For when God made the world, he had in his age-old plan that he wanted to become human.
  And he made the elements of the world, and they are in man, and man operates with them.
