Once upon a midnight dreary, while I studied social theory,
The basis of positivism, the why and the wherefore-
While I sat there, quietly reading, suddenly there came a beating,
And the sound of someone pounding, pounding at my chamber door.
"A shutter has come loose," I muttered, "and it's banging on my door -
Only this and nothing more."
Back to my theory turning, I read about man's yearning,
For the common good, prosperity, a rational end to war
And then again I heard a screech as of a giant bird,
It sounded like a raven tapping at my door
And I rose up from my chair and walked barefoot cross the floor;
