Final answer:
The passage provided is from John Milton's epic poem "Paradise Lost," which seeks to explain and justify the actions of God to mankind, unlike the personal themes of sonnets.
Step-by-step explanation:
The passage in question, "What in me is dark illumine, what is low raise and support; That to the height of this great argument, I may assert Eternal Providence, And justify the ways of God to men," is an excerpt from John Milton's epic poem "Paradise Lost."
This work is neither a sonnet by Shakespeare nor a portion of "Faust" or "Ode to a Nightingale." In contrast to the structured forms of Shakespearian and Petrarchan sonnets, which are composed of an octet and sextet, Milton's "Paradise Lost" is not confined by such structural parameters and is recognized by its blank verse and grand theological themes. The passage reflects the epic's central premise, where Milton seeks to illuminate and justify the actions of God to his readers, a theme that is vastly different from the personal expressions typically found in sonnets.
