This paper identifies and responds to four critiques of democratic contractarianism, as advocated in Democratic Justice and the Social Contract, to be found in this symposium. The first is that, as a contingent practice-dependent account of justice, democratic contractarianism lacks the capacity to explain civic cooperation. The second is that, despite its intentions, Democratic Justice does not lay out an authentic contractarian theory. The third is that the theory is incompatible with our considered judgements about justice. And the fourth is (...) that the ambition of Democratic Justice to use the empirical method to compensate for the failures of hypothetical contract theory fails because all social science needs interpretation. To each of these critiques, replies are offered, drawing attention to the way in which democratic contractarianism exemplifies a logic of social cooperation to mutual advantage that is compatible with justice provided the cooperation emerges from a bargaining situation of roughly equal power.
