Slavery has been the general lot of the human race..

"Although all men are born free, slavery has been the general lot of the human race. Ignorant--they have been cheated; asleep--they have been surprised; divided--the yoke has been forced upon them. But what is the lesson?…the people ought to be enlightened, to be awakened, to be united, that after establishing a government they should watch over it....It is universally admitted that a well-instructed people alone can be permanently free."

-James Madison
