Brian Barry and impartiality as the foundation of social justice
Impartiality, rather than mutual benefit, is essential to assess justice in institutions and the injustices hidden behind seemingly stable political balances
When feelings or devotion are not enough to resolve conflicts, the only way left is 'the use of reason, of impartiality, of reasonable compromise'. Thus opens, with this quote from Karl Popper, Justice as Impartiality (Clarendon Press, 1995), the second volume of British philosopher Brian Barry's great treatise on social justice. Impartiality is the key concept that can make an agreement just. We do not have to be altruistic, nor do we have to deny our identities, nor do we have to zero in on conflicts. Justice as impartiality' tells us something more subtle and at the same time more radical. It invites us to take seriously the idea that, in designing our institutions, no one can be worth more than another.
Why impartiality?
In order to understand how Barry comes to base his theoretical edifice on this principle, we need to go back to the starting point from which his entire critique develops: the idea that justice is only a cooperative equilibrium, a mutually beneficial compromise for all. This is the Humean tradition and the neo-contractualism of John Rawls and David Gauthier's Morals by Agreement: a just society is one that eliminates conflict and fosters cooperation because it generates 'mutual benefit' for all. Mutual welfare becomes the measure of what is just. Barry dismantles this paradigm sharply by pointing out how an equilibrium can be both stable and beneficial and unjust at the same time. Agreements can be 'accepted' because those in a disadvantaged position have no better alternatives. In this way, asymmetrical power relations that have nothing moral about them may be hidden behind cooperation and mutual advantage. The example of the noxious neighbours we analysed last week is emblematic in this respect: the agreement is 'mutually beneficial', but it is based on fear and vulnerability. The agreements thus obtained are not just but extorted by necessity. "A theory based on mutual advantage," Barry writes in Theories of Justice, "is necessarily corrupted by the asymmetry of positions" (1989, p. 48). If the only requirement of justice is mutual benefit, then the weaker will never reject anything. That is why we need impartiality.
Rawls had already tried this and Barry explicitly acknowledges it. The Rawlsian idea of the 'veil of ignorance' behind which, in the original position, the principles of the social contract are negotiated represents an attempt to introduce an element of impartiality in judgements and equality in starting positions. The attempt, however, is deemed incomplete by the British philosopher because behind the veil individuals continue to reason as rational maximisers. They do not know who they will be once the veil is lifted, but they do know that whatever they will be, they will have an interest to protect. Rawls 'cleanses' egoism, but does not overcome it (see Mind the Economy of 10/03/2024). Barry's impartiality demands something more: a method of justification that does not depend on interest, power, fear or lack of alternatives.
From this requirement emerges its 'fundamental criterion': a norm is just if no one, starting from conditions of moral equality, could reasonably reject it. The test for every principle of justice and every possible institution is not its acceptability, which can be forced, interested, necessitated, but its 'reasonable rejection'. For this we need impartiality. Any refusal can only be reasonable and free if all parties are in the same position of power, need, availability of resources, etc. Those principles that would be impossible to reasonably refuse if the starting conditions were of moral equality would be just.
