Charming, romantic, a little sexy even, yes? These lines crop up on “quotes about love” here and there. But the scene is not so romantic when you consider it’s being reported to you by an envious, voyeuristic Satan who is literally hellbent on revenge on Man. Here’s what’s actually around that quote:
Sight hateful, sight tormenting! thus
[these two imparadised blah blah blah bliss]
while I to Hell am thrust,
Where neither joy nor love, but fierce desire,
Among our other torments not the least,
Still unfulfill’d with pain of longing pines.
So the lines are really more an illustration of how Paradise is still agonizingly out of Satan’s reach on every possible level than they are a spectacular commentary on the magic of love or whatever.
Suck it, romantics. Milton will have none of your frippery.
