Milton

"Is this the region, this the soil, the clime,"
Said then the lost Archangel, "this the seat
That we must change for Heaven?—this mournful gloom
For that celestial light? Be it so, since He
Who now is sovran can dispose and bid
What shall be right: fardest from Him is best,
Whom reason hath equalled, force hath made supreme
Above his equals. Farewell, happy fields,
Where joy forever dwells! Hail, horrors! hail,
Infernal World! and thou, profoundest Hell,
Receive thy new possessor--one who brings
A mind not to be changed by place or time.
The mind is its own place, and in itself
Can make a Heaven of Hell, a Hell of Heaven.

--Milton, Paradise Lost, I
