I can tell you five reasons for the abolition of slavery that were included by Harriet Beecher Stowe in her 1852 novel, Uncle Tom's Cabin. Her book was popular with abolitionists around the world. The book was the 2nd-best selling book of the 19th century -- coming in behind only the Bible itself.
Five reasons Harriet Beecher Stowe gave against slavery:
1. Slavery went against the teachings of Christianity.
2. Slavery went against America's founding principles, such as that all men are created equal.
3. Slavery did not benefit the economy as was claimed. Educated persons are more industrious and do not have to be coerced to work by threats and oppression.
4. Slavery was inconsistent with the rule of law, because it put all power in the hands of slaveholders and did not account for legal rights for the slaves.
5. Slavery was keeping the South in a perpetual state of fear and instability, requiring brute force to keep down slave uprisings.
