"Ultimately, Slavery and Capitalism succeeds not because it offers a novel moral condemnation of slavery - something few would dispute - but because it reorients the historical and theoretical terrain on which such condemnations are made."

"McNally ranges across several centuries without the book ever feeling superficial or overly general. Instead, vivid stories pepper the text, drawn from colonial travel literature, planter records and diaries, slave narratives, and recent historical scholarship."
