Proslavery thought

Proslavery is support for slavery.^[1] It is sometimes found in the thought of ancient philosophers, religious texts, and in American and British writings especially before the American Civil War but also later through the 20th century. Arguments in favor of slavery include deference to the Bible and thus to God, some people being natural slaves in need of supervision, slaves often being better off than the poorest non-slaves, practical social benefit for the society as a whole, and slavery being a time-proven practice by multiple great civilizations.
