"Discussion on American Slavery" by George Thompson and Robert J. Breckinridge is a historical account written in the mid-19th century. This text presents a detailed debate between Thompson, an advocate for the abolition of slavery, and Breckinridge, a delegate from the Presbyterian Church in the U.S., regarding the moral and social implications of slavery in America. The main topic of the book revolves around the justifications and arguments concerning slavery, as well as the responsibilities of both Americans and Britons in addressing this contentious issue of human rights. At the start of the book, the culmination of correspondence between Thompson and Breckinridge lays the groundwork for their much-anticipated debate in Glasgow, Scotland. The introductory sections establish the context and urgency surrounding the issue of slavery in America during the 1830s, with both speakers articulating their views on the roles of Christian morality and societal obligation in this debate. Breckinridge expresses his hesitations about participating in the discussion, while Thompson is eager to defend his anti-slavery stance and confront the beliefs held by American ministers and slaveholders. This sets the stage for a rhetorical conflict where both men engage deeply with the ethical implications of slavery, seeking to persuade the public and uphold their respective arguments.
