Philosophy & Social Criticism, Volume 48, Issue 6, Page 860-881, July 2022. This article aims to rewrite Emerson’s moral perfectionism – his anti-foundationalist pursuit of an always more perfect state of self and society – onto his moral and intellectual participation in the abolitionist movement. I argue that Cavell artificially separated Emerson’s moral perfectionism from his extensive, decades-long abolitionism. The source of Cavell’s oversight is his participation in the long-standing norm of dichotomizing Emerson’s work into the theoretical ‘essays’ and the (...) ‘anti-slavery writings’ or the philosophical and the polemical. Recent scholars of Emerson have questioned and even dismissed this dichotomy, however, while recentring Emerson’s politics in his oeuvre as a whole. They find much to praise, and also plenty to criticize, in Emerson’s abolitionist writings. I follow and extend that scholarly trend here and introduce what I call Emerson’s abolitionist perfectionism as an expansion of Cavell’s influential work on moral perfectionism. (shrink)
