The "original position"

The agreement that stems from the original position is both hypothetical and ahistorical. It is hypothetical in the sense that the principles to be derived are what the parties would, under certain legitimating conditions, agree to, not what they have agreed to. Rawls seeks to use an argument that the principles of justice are what would be agreed upon if people were in the hypothetical situation of the original position and that those principles have moral weight as a result of that. It is ahistorical in the sense that it is not supposed that the agreement has ever been, or indeed could ever have been, derived in the real world outside of carefully limited experimental exercises.
