Famous quotes containing the word conclusion:
“I’ve heard the wolves scuffle, and said: So this
Is man; so what better conclusion is there
The day will not follow night, and the heart
Of man has a little dignity, but less patience
Than a wolf’s....”

“The conclusion has never changed: the worst sort of people come here for the worst sort of reasons and put upon those of us who have conveniently forgotten where we came from and how we got here.”
