Law as a Branch of Morality: The Unity of Practice and Principle

The article explores Dworkin’s suggestion that law and morality comprise a unified normative domain, considering similar suggestions by Greenberg and Hershovitz. It defends an interpretative approach to law, akin to Dworkin’s, against the view that the law’s content is determined by direct appeal to political morality at large, subject only to the effect of action by law-making institutions. Legal practice and political principle are in important ways interdependent, each capable of illuminating and clarifying the other. As an approximation of justice, grounded in practice, the law consists fundamentally in the moral principles that, in the final analysis, constitute the political community. The law’s content is an interpretative question, dependent on a grasp of practice that gives determinate shape to abstract concepts of equality and justice.
