Smith’s two-sentence rebuke of the slave trade was quoted in full several times in early anti-slavery literature. It helps us make sense of Part V of The Theory of Moral Sentiments and understand Smith’s posture toward slavery. Also, it might inform our understanding of the relationship between Smith’s two great works.
