  • About the Unicity of the Difference Principle and the Complementarity of Economics and Philosophy on the Question of Justice. Part 2: On the Complementarity of Economics and Philosophy Regarding Theories of Social Justice

    Abstract

    Rawls argued that the difference principle leads to see otherwise the differences of talents. Their distribution is a “common asset”, in particular for the worst off. Nozick had seen there the avowal that a Rawlsian Society considers itself as the owner of our qualities, of us, if one discards the fantasy of a “purified self”. Rawls had proposed a powerful criticism of the absence of a theory of the human persons in Utilitarianism, “not taking seriously the distinction between” them, but a similar argument would be valid against Rawls (‘Tu quoque!’). Nozick’s supposed confutation is a fallacy: not the set of the talents is a common asset, but their differential distribution is one, forming a good basis for complementarities (Rawls would allude to Ricardo, but Arrow, against Nozick’s argument, had made the same point in pointing an analogy with division of labour according to Smith). The answer is that we own our talents, but the environment that made their flourishing possible explains why we may understand that part of our benefices can be redistributed by society. Via Arrow, who quotes Pascal (“Qu’est-ce que le Moi ?”), one suggests that all purely welfarist conceptions lead to the elimination of the self in favor of a concept of individuals as “containers” of satisfactions. The debate between economists and philosophers is necessary. For instance, according to Rawls, a person is a legitimate source of claims for me, and not being reduced to a container of possible satisfactions, it is stratified in incommensurable levels.

  • About the Unicity of the Difference Principle and the Complementarity of Economics and Philosophy on the Question of Justice. Part 1: About the Unicity of Rawls’s Difference Principle

    Abstract

    Between (2,3) and (2,4), does the Difference Principle (DP) select the first one, the second one, or is it indifferent? That last interpretation is confirmed by Rawls’s use of the curve of the perfectly complementary goods. It admits curves of indifference. Once the worst off is maximized, one is indifferent between all the corresponding states. Leximin selects the second state: it iterates the Maximin on the “last” worst off. Sure, Leximin prefers (2, 10) to (2,3), and there is an intuitive point according which it is unjust that only the richest win anything; it cannot be called a “just” improvement, even if is a Pareto-improvement. In a co-operation, the poorest would be a “sucker”. My proposal is that an improvement can be called “just” iff it improves the situation of all (strong Pareto-improvements). Rawls (1999 [1971], § 17) noticed that if it is possible to go from (2,3) to (2,4), it is “surely” possible to go from (2,3) to (2+n, 4-n’), an improvement implied by Maximin, which is only the lexically first rule of justice of DP, to which one adds the secondary rule “Minimize inequality”. The curves in L are the curves of Maximin: DP has no indifference curves. There is an absence of ambiguity in DP. We are unable to generalize its univocity. Our intuitions on justice amid intermediate classes are vague. A component of justice is the solidarity of all. Nobody should stay alone in the same situation while only the situation of others improves.
