Criticisms of Rawls’ theory include pointing out that the original position might not be as Rawls presents it – it might not be as neutral as he maintains, and might stack the deck towards modern, individualistic social structures. Perhaps Rawls’ best-known critic is his Harvard colleague Robert Nozick (1938–2002). In his book Anarchy, State and Utopia (1974), he argues in favour of right-wing libertarianism.
