one should not be misled, then, by the somewhat unusual conditions which characterize the original position. The idea here is simply to make vivid to ourselves the restrictions that it seems reasonable to impose on arguments for principles of justice, and therefore on these principles themselves. Thus it seems reasonable and generally acceptable that no one should be advantaged or dis- by natural fortune or social circumstances in the choice of principles. It also seems widely agreed that it should be impossible to tailor principles to the circumstances of one's own case. We should insure further that particular inclina- tions and aspirations, and persons' conceptions of their good do not affect the principles adopted. The aim is to rule out those principles that it would be rational to propose for acceptance, however little the chance of success, only if one knew certain things that are irrelevant from the standpoint of justice. For example, if a man knew that he was wealthy, he might find it rational to advance the principle that various taxes for welfare measures be counted unjust, if he knew that he was poor, he would most likely propose the contrary principle. To represent the desired restrictions one imagines a situation in which everyone is deprived of this sort of information. One excludes the knowledge of those contingencies which sets men at odds and allows them to be guided by their prejudices. In this manner the veil of ignorance is arrived at in a natural way. This concept should cause no difficulty if we keep in mind the constraints on arguments that it is meant to express. At any time we can enter the original position, so to speak, simply by following a certain procedure, namely, by arguing for principles of justice in accordance with these restrictions.
