In philosophy, the original position is a hypothetical position from which members of society would consider which principles they would select for the basic structure of their society if they had no knowledge ahead of time regarding the position which they would end up occupying in that society. The idea of having no such knowledge, because everyone is behind a veil of ignorance, represents a thought experiment often associated with the work of the American philosopher John Rawls.
In this "original position", their position behind the "veil of ignorance" prevents everyone from knowing their ethnicity, social status, gender, and (crucially in Rawls's formulation) their or anyone else's ideas of how to lead a good life. Ideally, this would force participants acting rationally to adopt an "initial agreement" on the principles impartially.
