Abstract

Frank Michelman’s recent book Constitutional Essentials. On the Constitutional Theory of Political Liberalism is discussed from a specific angle, related to how Rawls’s ‘deflection procedure’ – called by Michelman ‘justification by constitution’ – is affected by two recent innovations in the paradigm of political liberalism: first, the extension of reasonable pluralism to a family of liberal political conceptions of justice that coexist in a liberal-democratic society; second, the idea of legitimation based on the criterion of reciprocity, aimed at supplementing the liberal principle of legitimacy. In the attempt to probe Michelman’s assessment of the impact of these two innovations, three critical points are mentioned, for each of them, that suggest a somewhat more sceptical attitude than Michelman’s about the capacity of ‘justification by constitution’ to remain substantially unaltered, once these innovations are in place.
