In the book Uncle Tom's Cabin briefly state the two opposing views of slavery found in the Bible.

For slavery:

"It's undoubtedly the intention of Providence that the African race should be servants, – kept in a low condition," said a grave-looking gentleman in black, a clergyman, seated by the cabin door. "'Cursed be Canaan; a servant of servants shall he be,' the scripture says." (Chapter 12)

Against slavery:

A man counters the above Bible quote with this one,

"Do unto others as you would have them do unto you."
