 The hypothetical contractualist model, then, regards moral principles as the result of a bargaining process among a group of agents, subject to certain restrictions that are specified so as to guarantee that the chosen principles will meet the demands of second-order impartiality. The most famous example of this approach is John Rawls’ ‘veil of ignorance’, as described in (Rawls 1971). According to Rawls, the principles of a just society are those that would be chosen by self-interested rational agents in the ‘original position’ – a position in which agents possess broad knowledge about human history and the nature of the world they live in, but are denied specific information regarding their own particular identities or prospects in the society in question, the nature of that society, and, crucially, the nature of their own particular conception of the good. Since nobody knows who they will be or what social position they will occupy, there is no opportunity for anyone in an advantaged position to take advantage of that position in order to force a less privileged party to concede to an otherwise unacceptable outcome. It is this fact that allows Rawls to claim that principles chosen under the veil of ignorance are guaranteed to be impartially acceptable to all – and thus, guaranteed not to be unjust.
