Reviewed by: Mastering Emotions: Feelings, Power, and Slavery in the United States by Erin Austin Dwyer Laura McCoy (bio) Mastering Emotions: Feelings, Power, and Slavery in the United States. By Erin Austin Dwyer. (Philadelphia: University of Pennsylvania Press, 2021. Pp. 320. Cloth, $39.95.) Erin Austin Dwyer’s intriguing new book brings together the histories of slavery and emotions to illuminate how Black and white southerners alike deployed emotions as “a currency of power” (3). Dwyer reads slave narratives alongside and against documents of enslavers to reconstruct people’s emotional lives. While it is never possible to know how other people truly felt, Dwyer analyzes the rhetoric used to discuss emotions, what emotions were expected of whom, motives for feigning or hiding specific emotions, and differences between emotional norms and actual emotional practices. In doing so, she uncovers “what people thought emotions could actually accomplish” (13)—in short, how power operated through emotions in both slavery and Emancipation. From the outset, Dwyer makes clear that the stakes of these affective politics were not even. For enslavers, deviating from emotional norms most commonly risked public scrutiny and potential loss of capital, while enslaved people “risked the whip, the auction block, or even death” (3). While historians of slavery have separately explored affective relations among the slaveholding class or enslaved communities, Dwyer considers affective relations between the two groups. This approach enables her to interrogate how individuals navigated power hierarchies through emotional expression and to convincingly contend that attending to emotions sharpens our understanding of how white southerners perpetuated and Black southerners resisted the politics of white supremacy during the years before and after the Civil War. The first chapter broadly explores how enslavers constructed their emotional lives and social identities through enslaved people and, in turn, how enslaved people could manipulate slave owners’ feelings and relationships to survive and resist enslavement. The second chapter explains how southerners learned the emotional politics of a society organized around slavery. Slaveholding parents actively taught their children how to master their own emotions and those of the people they enslaved. From enslaved adults, trickster tales, and the process of play, enslaved children learned how to mask sadness, read slaveholders’ emotions, and identify emotional allies—all affective strategies that could mean the difference between life and death. Together, these chapters emphasize that the emotional politics of slavery were socially constructed and thus intentionally reinforced or resisted. [End Page 246] The third and fourth chapters consider the rhetorical importance and literal commodification of emotions in a society dominated by market forces. For instance, members of the planter class linked the appearance of contentment to profitability, worrying that “sulky” slaves were poor workers and that crying or lashing out on the auction block depreciated an enslaved person’s value. Because trustworthiness had market value, enslaved people could strategically display honesty and loyalty to gain benefits like greater mobility. These chapters demonstrate how the market values of happiness and trust constrained enslaved people’s freedom of emotional expression while simultaneously providing opportunities for enslavers and enslaved people to negotiate their daily lives and material conditions. Chapters 5 and 6 explore the contours and consequences of affective discipline as a means of social control. Enslavers assumed the authority to coerce displays of desired emotions from enslaved people and punish them for expressing an emotion deemed inappropriate or threatening, such as grief or anger. The goal of affective discipline was not just to control enslaved people’s emotional expressions, but also to punish them for how they had made slaveholders feel. The final chapter examines Emancipation as “a seismic shift in the emotional terrain of the South” (162), in part because the planter class fretted over losing the power to affectively discipline Black people. Formerly enslaved people made clear that they believed being free meant the ability to pursue happiness and freely express emotions that had been restricted in bondage. Members of the planter class felt threatened by this emotional liberation and employed both legal and extralegal tactics to reassert the emotional hierarchies of slavery, especially the authority to control Black people’s emotions. The power of Mastering Emotions rests on Dwyer’s patient and nuanced readings of conflicting perspectives and...
