Abolitionists adopted higher law to oppose the settled law which explicitly recognized chattel slavery in America. Emerson sometimes spoke on higher law but it was not his most comfortable position. Emerson was a Neoplatonist, and it is the gradualism of Neoplatonism that he embraced against the immediatism implied in higher law. But even before Emerson’s 1856 conversion to abolition, starting in 1854 Emerson began moving his self-reliance into Northern-reliance. He was working his way philosophically toward a political activism that he would, finally, enthusiastically embrace. Emerson borrowed from the Neoplatonist Plotinus the word and idea of living “amphibiously,” and that is what he learned to do.
