Abstract
During the American Civil Rights Movement, Martin Luther King’s principal arguments reasoned from theological ethics, appealing to natural law, imago Dei, and agape love. Today in the United States, with the prevailing ideal of public reason, such arguments are unacceptable in the public square. In lieu of King’s theological arguments, are there philosophical principles or values adequate to sustain the cause of racial justice, establishing both a secure rational foundation for racial justice and providing sufficient moral incentive for citizens to work self-sacrificially for this cause? I assess the prospects of the major philosophical alternatives, specifically utilitarianism, Kantian ethics, virtue ethics, contractarianism, and the anti-theory option. I conclude that each of these approaches fails to provide the necessary conceptual resources to sustain the cause for racial justice. This presents a disconcerting dilemma: either we readmit theological considerations into the public square or surrender hope for the achievement of lasting racial justice in the United States.
