Nomic is a game created in 1982 by philosopher Peter Suber, the rules of which include mechanisms for changing those rules, usually beginning by way of democratic voting.[1] The game demonstrates that in any system where rule changes are possible, a situation may arise in which the resulting laws are contradictory or insufficient to determine what is in fact legal.
Its name derives from the Greek for "law", νόμος (nomos), because it models (and exposes conceptual questions about) legal systems and the problems of legal interpretation.
