 Stanley Cavell’s engagement with Emerson is the most original and prolonged by any philosopher, and Emerson is a primary source for his writing on “moral perfectionism.” In his earliest essays on Emerson, such as “Thinking of Emerson” and “Emerson, Coleridge, Kant,” Cavell considers Emerson’s place in the Kantian tradition, and he explores the affinity between Emerson’s call in “The American Scholar” for a return to “the common and the low” and Wittgenstein’s quest for a return to ordinary language. In “Being Odd, Getting Even” and “Aversive Thinking,” Cavell considers Emerson’s anticipations of existentialism, and in these and other works he explores Emerson’s affinities with Nietzsche and Heidegger.
