 Social contract theories also require some rules to guide the formation of agreement. Since they are prior to the contract, there must be some source of prior moral norms, whether natural, rational, or conventional. The first rule that is normally prescribed is that there must be no force or fraud in the making of the agreement. No one is to be “coerced” into agreement by the threat of physical violence. The reasoning for this is quite straightforwardly prudential: if one is allowed to use violence, then there is no real difference between the “contract” arrived at and the state of nature for the threatened party, and hence no security in the agreement. However, there is a fine line between being coerced by the threat of violence into giving up one’s rights and being convinced by the threat of penury to make an unfavorable agreement. For this reason contractarians like Gauthier are able to argue for a fair and impartial starting point for bargaining that will lead to secure and stable agreements. The second rule of contract is that each individual who is a legitimate party to the contract must agree to the rules of justice, which are the outcomes of the contract.
