In the cauldron of the antislavery movement, antislavery activists, such as William C. Nell, Thomas Sidney, and Charlotte Forten, and Transcendentalist intellectuals, including Ralph Waldo Emerson and Henry David Thoreau, developed a "Higher Law" ethos, a unique set of romantic political sensibilities-marked by moral enthusiasms, democratic idealism, and a vision of the self that could judge political questions from "higher" standards of morality and reason. The Transcendentalism that emerges here is not simply the dreamy philosophy of privileged white New Englanders, but a more populist movement, one that encouraged an uncompromising form of politics among a wide range of Northerners, black as well as white, working-class as well as wealthy. Invented to fight slavery, it would influence later labor, feminist, civil rights, and environmentalist activism.
