On page 18 of the published manuscript an error in the formatting of Jürgen Habermas’ name was introduced into the reference list. These references have been corrected below:
Habermas, Jürgen (1990) Strukturwandel der Öffentlichkeit. Frankfurt/M.: Suhrkamp Verlag.
—— (1997) ‘Kant’s idea of perpetual peace, with the benefit of two hundred year’s hindsight’. In James Bohman and Mathias Lutz-Bachmann (eds), Perpetual Peace: Essays on Kant’s Cosmopolitan Ideal (Cambridge, MA: The MIT Press), 113–54.
The publisher apologies for the mistake.
