Theories of Justice: Rawls, Nozick and Walzer - Summary

Distributive Justice

Theories of distributive justice provide moral accounts of how the benefits and burdens of social existence should be distributed amongst the members of a society. Some principles may call for radical redistribution (eg, communism with its egalitarian ethic). Some theories may suggest that people should be given a share of the social product proportionate to their merit, effort or desert (just desert theory). Other theories hold that benefits and burdens should be left where they are distributed by the operation of a market.

John Rawls: A Theory of Justice

John Rawls’ theory of justice as fairness has been the most influential distributive justice theory of the last 50 years (see John Rawls A Theory of Justice). Rawls’ theory is complex but has the following characteristics: -
(i)                 It deals with the way we would organise the laws and institutions of a society, it does not seek to deal with the allocation of each and every possible item.
(ii)               Rawls’ methodology says that a distribution will be just if it is fair and it is fair if it is a distribution we would agree to if we were seeking to establish the principles for distribution within a society (the original position) in circumstances where we had no knowledge of our own characteristics and what would advantage or disadvantage us (the veil of ignorance).
(iii)             Rawls argues that it would be rational if we were in the original position behind a veil of ignorance to agree to a general rule of egalitarianism, with inequality tolerated where it satisfied Rawls’ difference principle.
(iv)             The difference principle allows inequality where it can be shown to be to the benefit of the worst off members of the society.
(v)               Rawls sought to justify his difference principle by appeal to so-called “maximin theory” (ie, ensuring the best possible worst outcome. This is similar to what is sometimes called the “precautionary principle”).
Rawls difference principle is quite stringent. In arguing for it Rawls rejected utilitarianism and its concept of expected average utility. This would permit inequality wherever it could be shown that the inequality would improve overall welfare. Rawls’ arguments for his difference principle are far from convincing and have been much criticised.
Rawls opposed the concept of justice as desert. Many inequalities in our society stem from the differential rewards given to natural talent. Rawls argued that we did not deserve our natural talents and therefore it made no sense to suggest we deserve what those talents can earn. (eg, Pavarotti did not deserve his voice, and therefore cannot deserve the millions that his voice might earn).
Some have argued that Rawls’ theory of justice would produce something akin to the classical welfare State of Australia, Britain or Scandinavia in the 1960’s and 1970’s. Redistributive taxation would be justified by Rawls, subject only to his difference principle. Others have argued that a Rawlsian society would be far more radically redistributive then a classical welfare state, while others have argued that it may in fact involve quite wide disparities justified by the difference principle.

Robert Nozick: Rights and Entitlement Theory

Robert Nozick in his book Anarchy State and Utopia criticised Rawls’ theory on several grounds. Nozick offered his "Entitlement theory" argued that if people have rights and exercise them freely inequalities will occur as the natural result of the exercise of that liberty (Nozick’s Wilt Chamberlain example).
Nozick argued that Rawlsian distributive justice involves constant interference with the exercise of individuals’ liberty and freedom of choice.
Nozick argued that the notion of desert was too stringent. Even if I do no deserve something I may be entitled to it (eg, my health, my relationships with my friend’s family, etc). If I am entitled to my natural talents Nozick argued, then this entails that I may be entitled to the benefits derived from using and exercising my natural talents.
Nozick argued that if people had rights and liberty, justice should not be concerned with the distribution of social benefits and burdens that results from the free exercise by citizens of those rights. Justice theory should concentrate on whether or not people’s rights have been violated.
Nozick argued that a distribution will be just if has come about through conduct that did not involve the violation of people’s rights. In other words, that its history did not involve misappropriation or other violations. Nozick argued against Rawls that justice theory should not be concerned with the end state pattern of distribution provided there has not been misappropriation.
An important criticism of Nozick’s historical entitlement theory is that we are not concerned with founding a society from scratch. Any distribution in any existing society is in part the result of past injustices. It would not appear to be just to apply the historical entitlement principle unless we first sought to correct for the effect of past injustices. The effect of those injustices may be so diffused and tied up with the existing distribution that such correction cannot take place. Any historical entitlement theory must confront the problems and paradoxes of whether it is in fact possible to reverse the effects of past injustices.

Walzer: A Pluralist Justice Theory

Michael Walzer in his work Spheres of Justice argued that there is not one principle of justice applicable to all possible social goods. Walzer argued that the applicable principle will depend upon the nature of what is to be distributed. Political power should ideally be distributed equally.  Professional positions should be distributed on the basis of merit and ability. Some benefits should be distributed in accordance with the outcome of market operations, and others on the basis of need.

Laws and Justice

Within the legal system there appears to be no single principle of justice but several operating at once. Property law appears to reflect a rights base and historical concept of justice. Income tax laws appear concerned with redistribution. Some might view tort law as redistributive, while others might view it as merely restorative of pre-accident distributions.
What type of distributive justice principles appear to justify: -
(a)                Succession law
(b)               Trade practices law
(c)                Anti discrimination law
