Probably my favorite part of Paradise Lost. Satan is reflecting on why he's unable to appreciate the beauty of Eden and why he feels compelled to destroy it.
With what delight could I have walkt thee round
If I could joy in aught, sweet interchange
Of Hill and Vallie, Rivers, Woods and Plaines,
Now Land, now Sea, & Shores with Forrest crownd,
Rocks, Dens, and Caves; but I in none of these
Find place or refuge; and the more I see
Pleasures about me, so much more I feel
Torment within me, as from the hateful siege
Of contraries; all good to me becomes
Bane, and in Heav'n much worse would be my state.
But neither here seek I, no nor in Heav'n
To dwell, unless by maistring Heav'ns Supreame;
Nor hope to be my self less miserable
By what I seek, but others to make such
As I though thereby worse to me redound:
For onely in destroying I finde ease
To my relentless thoughts […].
(Book 9, lines 114-130)
It shows that Satan is a fully realized character in his own right. In fact, as a character, he has more psychological depth than any other character in the poem.
But more importantly, it's an insightful observation about how our emotional state transforms the world to match it and how our unwillingness to accept the things we cannot change can taint everything. Everywhere Satan goes is hell, even if it's heaven, because he makes it that way.
I really don't know why anyone reads my blog.
