 In a similar vein, Angela Kallhoff argues that some (but not all) public goods provide additional externalities that are essential for the functioning of a democracy (Kallhoff 2011, 2014). Some public goods constitute visible expressions of solidarity and social justice among citizens (“central goods”), some support connectivity and serve as representations of shared interests (“connectivity goods”), and some serve as visible representations of a shared sense of citizenship (“identification goods”). The absence of these goods would undermine the ability of the citizenry to engage in public deliberation and develop a sense of self-determination.
