Abstract
Philosophical investigation of human nature has a long, distinguished, and
multifaceted history. In the East some of the most heated philosophical disputes pertaining to issues concerning moral self-cultivation centered on disagreements about human nature. Within the Neo-Confucian tradition that developed out of Korea, issues concerning human nature took center stage in a dispute now known as the “Horak Debate” that began in the eighteenth century. In this paper I seek to introduce the Horak Debate to contemporary philosophers by (a) historically situating the debate within the tradition of Korean NeoConfucianism, (b) providing an outline of the Horak Debate and identifying its central points of contention, and (c) demonstrating the debate’s philosophical significance by revealing how some of its key issues are rooted in disagreements that continue to concern contemporary philosophers.
