'Roger lived in the same spiritual world as the evangelical abolitionists. If this meant that he lacked some of the detachment of secular historians, it also gave him unrivaled insights into the historical meaning of sin, redemption, Providence, and retribution. As a mediator and interpreter, with one foot in the world of James Stephen and Wilberforce and the other foot in the world of modern academia, he has enriched our understanding of the abolitionists' motives, perceptions, strategies and contradictions.'
