Shared intentions,public reason,and political autonomy

John Rawls claims that public reasoning is the reasoning of ‘equal citizens who as a corporate body impose rules on one another backed by sanctions of state power’. Drawing upon an amended version of Michael Bratman’s theory of shared intentions, I flesh out this claim by developing the ‘civic people’ account of public reason. Citizens realize ‘full’ political autonomy as members of a civic people. Full political autonomy, though, cannot be realised by citizens in societies governed by a ‘constrained proceduralist’ account of democratic self-government, or the ‘convergence’ account of public justification formulated recently by Gerald Gaus and Kevin Vallier.
