John Rawls: A Theory of Justice (excerpt)

[...]

We should not attempt to give form to our lives by first looking to the good independently defined [e.g. the pursuit of happiness, pleasure or philosophy]. It is not our aims that primarily reveal our nature, but rather the principles that we would acknowledge to govern the background conditions under which these aims are to be formed and the manner in which they are to be pursued. For the self is prior to the ends which are affirmed by it; even a dominant end must be chosen from among numerous possibilities [...] We should therefore reverse the relation between the right and the good [...] and view the right as a prior.

[...]

Only if the self is prior to its ends can the right be prior to the good. Only if my identity is never tied to the aims and interests I may have at any moment can I think of myself as a free and independent agent [...] thus a moral person is a subject with ends he has chosen [...] the main idea is that given the priority of right, the choice of our coception of the good is framed within definitive limits. (560-563)

It seems that the principle of utility is incompatible with the conception of social cooperation among equals for mutual advantage. It appears to be inconsistent with the idea or reciprocity implicit in the notion of a well-ordered society. Or, at any rate, so I shall argue.

I shall maintain instead that the persons in the initial situation would choose two rather different principles: the first requires equality in the assignment of basic rights and duties, while the second holds that social and economic inequalities, for example inequalities of wealth and authority, are just only if they result in compensating benefits for everyone, and in particular for the least advantaged members of society. These principles rule out justifying institutions on the grounds that the hardships of some are offset by a greater good in the aggregate. It may be expedient but it is not just that some should have less in order that others may prosper.

[...]

We see then that the difference principle represents, in effect, an agreement to regard the distribution of natural talents as a common asset and to share in the benefits of this distribution whatever it turns out to be. Those who have been favored by nature, whoever they are, may gain from their good fortune only on terms that improve the situation of those who have lost out. The naturally advantaged are not to gain merely because they are more gifted, but only to cover the costs of training and education and for using their endowments in ways that help the less fortunate as well. No one deserves his greater natural capacity nor merits a more favorable starting place in society. But it doesn't follow that one should eliminate these distinctions. There is another way to deal with them. The basic structure can be arranged so that these contingencies work for the good of the least fortunate. Thus we are led to the difference principle if we wish to set up the social system so that no one gains or loses from his arbitrary place in the distribution of natural assets or his initial position in society without giving or receiving compensating advantages in return.

[...]

The natural distribution is neither just nor unjust; nor is it unjust that persons are born into society at some particular position. These are simply natural facts. What is just and unjust is the way that institutions deal with these facts. Aristocratic and caste societies are unjust because they make these contingencies the ascriptive basis for belonging to more or less enclosed and privileged social classes. The basic structure of these societies incorporates the arbitrariness found in nature. But there is no necessity for men to resign themselves to these contingencies. The social systems not an unchangeable order beyond human control but a pattern of human action. In justice as fairness men agree to share one another's fate. In designing institutions they undertake to avail themselves of the accidents of nature and social circumstance only when doing so is for the common benefit. The two principles are a fair way of meeting the arbitrariness of fortune; and while no doubt imperfect in other ways, the institutions which satisfy these principles are just. A further point is that the difference principle expresses a conception of reciprocity. It is a principle of mutual benefit. We have seen that, at least when chain connection holds, each representative man can accept the basic structure as designed to advance his interests.The social order can be justified to everyone, and in particular to those who are least favored; and in this sense it is egalitarian.

Perhaps some will think that the person with greater natural endowments deserves those assets and the superior character that made their development possible. Because he is more worthy in this sense, he deserves the greater advantages that he could achieve with them. This view, however, is surely incorrect. It seems to be one of the fixed-points of our considered judgments that no one deserves his place in the distribution of native endowments, any more than one deserves one's initial starting place in society. The assertion that a man deserves the superior character that enables him to make the effort to cultivate his abilities is equally problematic; for his character depends in large part upon fortunate family and social circumstances for which he can claim no credit. The notion of desert seems not to apply to these cases. Thus the more advantaged representative man cannot say that he deserves and therefore has a right to a scheme of cooperation in which he is permitted to acquire benefits in ways that do not contribute to the welfare of others. There is no basis for his making this claim. From the standpoint of common sense, then, the difference principle appears to be acceptable both to the more advantaged and to the less advantaged individual.
