Rawls on Freedom and Equality

In my last posting I looked at and provided an exegetical reading of Rawls' first lecture on Kantian constructivism as published in The Journal of Philosophy. In this posting I turn to the second of Rawls' lectures in which he turns from the discussion of autonomy to the views of freedom and equality and how these features of the person are represented in the original position. This lecture also features an extended account of the notion of publicity and its place within a Kantian view.

Rawls opens this second piece however by returning to the "model-conception" of a well-ordered society. In returning to this Rawls points out that the model-conceptions he is discussing are special cases of even more general notions but he does not here undertake to determine the way of describing the latter. A well-ordered society is a self-sufficient association which strives to perpetuate itself but is also a closed system. It is viewed as productive, that is, as giving itself its own means of support and not, as is the case in some utopias, as essentially not in need of labour. The "circumstances of justice" under which it exists are both subjective and objective. The objective form of these is that there is moderate scarcity, the subjective form is that there exists contrary conceptions of the good within the society. Despite the subjective circumstances of justice the citizens of the well-ordered society take their institutions to satisfy their public conception of justice. This point is introduced as the manner in which we can both understand the way that citizens are able to have a dual view of justice and as the basis for a distinction between different levels of the notion of publicity.

Rawls distinguishes three levels of publicity. The first level is in terms of the principles of justice. These principles of justice meet the conditions of institutions defined in Theory. They are accepted by all and the knowledge that they are is itself general. They are also supported by the general consensus beliefs held and so buttressed in an epistemic way by "common sense". Since Rawls is working throughout with the conception of a modern democratic society this includes the methods and practices of scientific inquiry and its findings when taken to be settled. The final level of publicity includes the "complete" justification of the public conception of justice which is also taken to be fully known or at least publicly available. This "full justification" includes the connection between the model-conceptions of the person and social cooperation. A "full publicity condition" is met when a well-ordered society meets all these conditions. Such a full condition expresses fair terms of cooperation and is hence Reasonable.

The full condition is also one that is appropriate, according to Rawls, for the restricted purposes of political justice and may be less compelling for other moral notions. Given the principles of justice apply to the political constitution and to all basic institutions, and that such can shape the character and aims of the members of society, the fundamental terms of this cooperation should answer to the requirements of "full" publicity. When institutions are capable of answering to such requirements citizens can account for their beliefs in them in such a way that their account will strengthen the institutions themselves. Publicity thus ensures that free and equal persons are in a position to accept the background social influences that shape their conception of themselves as persons.

For many other moral notions public agreement cannot be reached so consensus is limited in scope to the public moral constitution and its associated terms of cooperation. With regard to public questions ways of reasoning and forms of evidence have to be presented in such a way that they are generally accessible. The conception of a well-ordered society applies to the notions of the good held by citizens the principle of liberty (effectively toleration) held previously by religion alone. The basis for this is precisely due to the role of publicity in the justification of the principles of justice.

Parties to the construction of the original position assess conceptions of justice subject to the constraint that their principles can be public conceptions. The basic level of publicity cannot be met unless there is agreement on rules of evidence and forms of reasoning and these must be limited to those allowed by forms of reasoning as given to "common sense". Unless this stipulation is made no agreement is possible. So, whilst particular views of the good may hold certain institutions and policies to be wrong, the holding of them lacks public force if it does not meet these criteria of common sense (or public reason). Agreement within the original condition is thus not just on principles of justice but also on the ways of reasoning and rules of weighing evidence. The subjective circumstances of justice thus determine ways in which agreement can be articulated.

The second level of publicity concerns the way that general beliefs of social theory and moral psychology enter which is as publicly known to the parties to the construction. Citizens are aware of the factors that support the principles of justice as stated in forms that are common. This does not mean all factors that might support such beliefs are admissible within the process of reasoning since those which belong to controversial doctrines or are stated in ways which cannot avoid such controversy are not public doctrines in Rawls' sense. The articulation of the agreed principles of justice is not required to overcome the subjective circumstances of justice. Rather, it is assumed that only coercion could overcome such circumstances and this would subvert the point of reaching agreement. 

Rawls' careful articulation of public doctrines does not require decision on the truth of the doctrines disallowed public roles. It does however play a role in indicating that whilst fundamental disagreement may never be overcome that such disagreement need not have adverse effects in society. The fundamental principles need to be justified in ways that are impartial to the differences within society if the subjective circumstances of justice are to be respected. 

Only after these points about publicity and public reasoning have been stated does Rawls turn to the account of freedom and equality that is the principal purpose of the second part of his treatment. Moral persons were argued in the first part to be moved by higher-order interests to exercise moral powers. Within a well-ordered society citizens are free in the sense that they hold themselves entitled to make claims on the design of social institutions. Such claims are based on the self-conception persons have within this society which is that they take themselves to be self-originating sources of valid claims.  A second aspect of freedom is that free persons recognize each other as having the moral power to form and articulate a conception of the good. Following from this second element of freedom is that citizens, as citizens, are assumed to have a reflective capacity to reflect on and to alter any final ends they have. Another way of putting this second element of freedom is that the citizens are essentially independent of the particular conceptions of the good they espouse since their public identity is not dependent on any particular such view. In private life such a conception does not apply since privately we take our views to be integral to our identity but this does not affect the public ideal of social cooperation.

Returning to the notion of a well-ordered society Rawls next states that we assume in this that citizens are fully cooperating members of it over the course of their life so the ideal of it does not include special conditions that prevent this being actualized at given times. This helps to make clearer the notion of equality that is here being worked with which states that the public conception of justice is one that all are capable of honouring and of being participants in. All are thus viewed as equally worthy of being represented in any procedure that determines the principles of justice that regulate the basic institutions of society. This does not mean that we don't allow, in the structure of the society, for the fact that some, by virtue of special abilities, may be better qualified to hold offices and positions but only that all, as equal citizens, are assumed to have a sense of justice that is equally sufficient relative to what is required of them.

Rawls next returns to the original position and observes that within it the two powers of moral persons are represented formally as, for example, we do not here give any specific content to the sense of justice possessed to parties within it. So the first power means here only that all participants can follow the most reasonable conception of justice. The second capacity is similarly presented formally meaning that the parties are assumed to be able to have a sense of the good. But parties are also here determinate persons in the sense that both these powers would, after the removal of the veil of ignorance, have specific content. But there is no antecedent principles external to the argument of the position to which anyone has to refer to derive their principles. Freedom as independence is represented in how the parties give priority to guaranteeing the conditions for realizing their highest-order interests. Given that parties can stand above their conceptions of the good and judge them they are independent from them.

The Kantian conception of the veil of ignorance is also stated by Rawls to involve this veil being "thick". It is not only, as with Hume, that we wish to prevent parties from reasoning according to threat advantage. We further wish to prevent specific given notions of the good from being decisive in determining the basis for general agreement. This thicker veil is thus intended to ensure the fullest recognition of the equal status of persons by preventing even the higher-order (but not highest-order) interests of some from weighing more than others. Equality is represented within the original position by taking rights and powers within the procedure of it to be distributed to all. The only relevant feature here is that the capacity for moral personality is fulfilled and accidents of fortune are given no place within the construction. 

Rawls unhappily concludes the second lecture with two misleading contrasts between his approach as articulated here and Kant's own views. The first contrast is between the primacy of the social in the view and the "individual" focus of the Categorical Imperative. This contrast is misleading since Rawls argues that the principles of social justice are understood by Kant to follow from personal considerations of a sort that weigh in moral decisions strictly so called. In fact the supreme principle of right is not derived from such personal considerations even though it is clearly related to the Categorical Imperative itself. The basis of such derivation is a lengthy and difficult question but suffice it to say that the rationale for treating one in relation to the other concerns the overall conditions for the possible sustaining of just relations and is not grounded on personal matters. Rawls' suggestion to the contrary here is based on a very loose reading of the Doctrine of Right, a work he nowhere gives any sustained interpretation of, including, surprisingly, in his lectures on political philosophy (which don't include lectures on Kant).

The second contrast concerns the relationship between Rawls' notion of the "full" publicity requirement and Kant's idea of the "fact" of reason. Here Rawls is emphasizing that his view of autonomy is based on the way that publicity conditions enable it to be given form. By contrast he takes the "fact" of reason to just imply a mysterious basis to autonomy. In fact Kant's account of publicity (as stated in Perpetual Peace) has no essential relationship to the idea of autonomy in his moral philosophy and nor does Kant model political philosophy by it though he does instead discuss a relationship between freedom and independence that has correlates with Rawls' view of full autonomy. Rawls' comparison here mixes up levels of articulation of his doctrine by reference to Kant's and is singularly unhelpful in enabling a relationship between them to be stated.

Rawls on Autonomy

In 1980, almost a decade after publishing A Theory of Justice,  Rawls delivered three lectures on the topic of "Kantian Constructivism in Moral Theory" which were subsequently published in The Journal of Philosophy (from which page numbers are given). Over a series of postings I intend to present an exegesis of these lectures beginning here with the first which concerns the distinction between what Rawls terms "rational" and "full" autonomy. 

In opening the first lecture Rawls refers to the need to consider aspects of justice as fairness that he has not previously emphasised and to "set out more clearly the Kantian roots of that conception". This rationale for the lecture is set alongside a separate one of simply aiming to make the notion of Kantian constructivism more familiar. However the first rationale will be the more important given that what is being made familiar is integrally related to the further working out of the normative implications of A Theory of Justice.

The first part of the first lecture begins with a description of Kantian constructivism as specifying a conception of the person in a reasonable procedure of construction. Otherwise put the constructivist view being advanced sets up a procedure of construction that answers to certain requirements and the latter are understood to have their force in their reasonableness. Essentially the idea is to buttress the apparatus of Theory by showing how there is a connection between the person, as understood in a certain way, and the first principles of justice. The connection is by means of "a procedure of construction". 

Having begun by stating this point about the relation between the sense of the person and the first principles of justice Rawls goes on to argue that the conditions for justifying the latter require a public culture that is capable of sustaining them. In the absence of a sufficient basis for agreement amongst citizens the task of specifying a principle of justice becomes one of showing what is most reasonable to accept given a conception of the person. Within "democratic culture" as Rawls understands it here, which understanding is very broad, it is a sense that persons have moral capacities of a sort that is key. These moral capacities are what permit us to sustain the idea of treating persons as free and equal. If there is dispute at present over the way in which justice is centrally understood democratically then the Kantian procedure has to be one of demonstrating which principles of freedom and equality most reasonably meet the conditions of potential agreement.

Phrasing the beginning of his inquiry in terms of democratic culture ensures that Rawls conceives of his inquiry in a restricted way. It is not trans-historical but rather an inquiry concerned with modern conditions and it is not trans-cultural as it assumes the basic shape of democratic society. Further there is a form of hermeneutic at work in the inquiry being undertaken that expresses the view that there is at least a desire for agreement on the basic principles of justice. This desire for agreement is traced back here to the notion of "common sense" with Rawls assuming that it is either the case that we need to articulate the notions inherent within it or to propose to it instead conceptions and principles that are congenial to its "essential" form. As he further puts this:


The real task is to discover and formulate the deeper bases of agreement which one hopes are embedded in common sense, or even to originate and fashion starting points for common understanding by expressing in a new form the convictions found in the historical tradition by connecting them with a wide range of people's considered convictions: those which stand up to critical reflection. (518)

The way the process of disinterring from common sense the resolution of the problem modern democratic culture is apparently faced with is by means of articulation, in the first instance, of a conception of the person that is affirmed within this culture or that will be acceptable to those formed by it once critical reflection on it has taken place.

So Rawls is concerned with a "public conception" of justice that can be affirmed by all who regard their person in a certain way. This idea is part of the way that Rawls now understands the notion of "congruence" as what has to be provided is a conception of justice that fits our "deeper understanding of ourselves and our aspirations". This entails then that it fits the way that moral psychology resonates with us. This is reinforced by the view that the history and traditions embedded in this public life are resonant with the reasonable doctrine that is so uncovered. This does have a radical implication: "Apart from the procedure of constructing the principles of justice, there are no moral facts" (519).

After introducing the topic like this Rawls next specifies the way in which the conflict within democratic culture is understood by him although the ways he characterises this conflict is not singular. It is between two different traditions and one of them is associated with Locke, the other with Rousseau. However Rawls also refers to the difference Benjamin Constant spoke of between the liberties of the moderns and the liberties of the ancients with Locke associated with the moderns (and thus Rousseau with the ancients). The modern Lockean conception is concerned with civil liberties especially liberties of thought and conscience and also property rights and rights of association. The other ancient Rousseauist conception begins instead from equal political liberties and views civil liberties as subordinate. This appears to imply, in Kant's own terms, that Locke essentially provides the rudiments of a doctrine of private right whilst Rousseau provides one of public right and the task is bringing them together (as Kant sought to do in the Doctrine of Right).

Now in working out a way of specifying notions of freedom and equality that bring together these traditions Rawls introduces the idea of "model-conceptions" as embedded in his notion of justice as fairness. The two key notions in question are those of the "well-ordered society" and a "moral person". The "original position" is now presented as a third model-conception that mediates between the other two (and hence provides us with the means of understanding the process of construction). The means by which the "original position" works is by showing ways in which the citizens of a well-ordered society would have, using the capacities of moral persons, selected the principles that created their own society.

In the original position we begin, however, with a more restricted sense of the persons within it as being only rationally autonomous whereas the citizens of the well-ordered society would be fully autonomous. Rationally autonomous agents are those who possess the powers of formulation of hypothetical imperatives. Before proceeding further with a discussion of rational autonomy, however, Rawls first proceeds to describe the well-ordered society. Such a society would be regulated by a public conception of justice in the sense formulated by his account of institutions in the first section of Theory. This conception would be one understood to be accepted by all and known to be so shared. Further the basic structure of the society would be taken to actualize the conception of justice so understood and would be founded on reasonable beliefs. Within this arrangement the members of the society would treat each other as free and equal moral persons.

Moral persons would all possess the capacity to have a sense of justice and would have an equal right to determine the first principles of justice on which their society was governed. The freedom of these persons would consist in their ability to make claims on the design of institutions in the name of their fundamental aims and higher-order interests. The view of the well-ordered society is used to provide constraints on the way the original position should be set up as the idea that persons are free and equal has to be given place within the original position. In so beginning it operates fairly between persons and thus we have the idea that the procedure in question will settle the principles of justice fairly, an idea that is captured in the notion of justice as fairness.

Rawls' means of picturing the original condition is augmented, as in Theory, by the use of the device of the veil of ignorance. It is intended that the introduction of this device will ensure fairness between persons and thereby provide what Rawls terms "pure procedural justice". The principles of justice are to be constructed by a process of deliberation in which no antecedently given principles are given any particular weight. It is clear though that if a principle weighs heavily against rational assessment of interests it would be rejected. If the citizens of a well-ordered society are such as would regard themselves as moral persons then the parties to the original position must be such as to enable this self-conception to arise.

Having stated this much Rawls describes the capacities he takes to be essential to having moral powers. These are the capacity for an effective sense of justice on the one hand and the capacity to form and revise a rational conception of the good on the other. Persons have higher-order interests to realize and exercise these powers. These interests are then the ones that supremely have to be regulative of how the operation of the original condition is defined. We take the parties also to be "developed" morally in the sense that they aim at particular conceptions of the good. There is also a higher-order interest that each has of being able to prosecute this but this interest is not highest-order like that of realizing and exercising moral powers.

For the veil of ignorance not to prevent recognition of the powers so described we have to specify a means by which rational agreement can plausibly be reached. This is by means of an account of primary goods which will provide a yard-stick by means of which the parties to the original position can evaluate conceptions of justice. The primary goods are described here as including basic liberties (of Lockean sort), freedom of movement, powers and prerogatives of offices, incomes and wealth as all-purpose means and the social bases of self-respect. Primary goods are in general singled out as those generally necessary all-purpose means to enable us to realize and exercise our moral powers. The specified highest-order interests of persons thus select what is to count as a primary good.

So when we state that conceptions that would fail to recognise the interests of the parties to the agreement would fall, we are referring not to material interests, but rather to the interest they all have in enabling each other to develop and protect their moral powers. In the original position, therefore, the parties to the agreement are autonomous in not being bound beforehand by any given conception of justice but also in being moved solely by their highest order interests. This is what Rawls understands as the "rational autonomy" of the parties.

Full autonomy, by contrast, requires a further specification of social cooperation. Rawls argues that the notion of social cooperation contains two elements. The first is a sense of the fair terms of cooperation and these include conditions of reciprocity and mutuality. This element of cooperation is what Rawls now terms the Reasonable. The other element of cooperation, by contrast, is what he calls the Rational. The rational element of social cooperation concerns what each party to the cooperation in question is hoping to achieve by means of this cooperation. In the original position we have determined the rational by means of higher-order interests and acting rationally in relation to these interests includes adopting principles of instrumental reason. The Reasonable, by contrast, is incorporated into the background setup of the original position including in the sense that this position has to meet conditions of publicity.

The original position is set up to represent the minimum adequate notions of moral personality and when to this is added the sense equals in all relevant respects are to be treated equally this idea is meant to ensure that the original position is described in a way that is fair to all members of the agreement. The first subject of justice is also to be the basic structure of society or its main social institutions. 

The summation of the remarks Rawls presents here about the Reasonable and the Rational are to the effect that the Reasonable presupposes and subordinates the Rational. The Reasonable defines the fair terms of cooperation but it presupposes the Rational as without a sense that there are distinct conceptions of the good there is no real point to such cooperation. It restates essentially the argument made in Theory for the priority of the right over the good.

Full autonomy is a moral ideal that is part of the comprehensive ideal of the well-ordered society. Rational autonomy, by contrast, is the device by means of which the conception of the person is related to the procedure of arriving at definite principles of justice.

Rawls and Alternative Views of Justice

In my last posting on Rawls I looked at his response to "common sense" precepts of justice. There we discovered some reasons why "common sense" precepts are at the wrong level of generality to serve as primary principles of justice. However, Rawls concludes Chapter V of A Theory of Justice by considering two other alternatives to his argument for the two principles as the right ones to be adopted in the original position. In section 49 he addresses "mixed" conceptions of justice and in section 50 concludes with a response to the arguments that have been presented for a principle of political perfectionism. In this posting I will look at these arguments in turn.


At the opening of section 49 Rawls makes clear that the "mixed" conceptions considered are ones that require the adoption of the first principle of justice and, concomitantly with this, also agree to its lexical priority over the preferred second principle where this second principle is thought to have replaced the complicated conjunction of fair equality of opportunity and the difference principle that Rawls has advocated as required. So essentially the "mixed" conceptions supplement the liberty principle with something different than the directly egalitarian concerns Rawls has presented them with. An obvious example of a "mixed" conception would be a combination of the liberty principle with the principle of utility where, however, given lexical priority, the principle of utility would be subordinate to the liberty principle. 


Such "mixed" conceptions would be in the classic position of intuitionist positions generally on Rawls' view which is that they would lack precision in application. You could, for example, view the second principle as a combination of "average" utility with some chosen minimum level of agreed income but it would still be an open question how to govern the relations between these elements. Effectively it might well be the case, Rawls suggests, that the difference principle would be being covertly appealed to in such a case. The difficulty here is much as with the appeal to "common sense" precepts which is that the intuitive nature of the combination in question leaves much undecided and without evident mechanisms available for decisions to be made. The difference principle, by contrast, allows for a direct form of appeal to be made in evaluation of decisions and this is a clear advantage of it.


Appeal to utility, even in a combined or "mixed" conception, constantly creates the problem of how the utility functions are to be measured. Maximisation has to include some measurement function and perhaps the most obvious one is the zero-one claim (everyone's preferences to count for one and no more than one). However this leaves a lot undecided between positive and negative outcomes and could lead, for example, to a preference for a large population that was relatively uneducated on the grounds that greater net utility was more easily achieved given greater numbers and fewer wants, an outcome that is, to say the least about it, not intuitive. (To see that Rawls' argument here is far from implausible it suffices only to consider what Parfit, in Reasons and Persons, termed the Repugnant Conclusion.)  Generally speaking "mixed" conceptions that involve the principle of utility can be objected to both on grounds that they involve unacceptable uncertainty given their intuitionist basis and unacceptable risks given their utilitarian element. 


In section 50 Rawls gives the principle of political perfectionism his attention and distinguishes between an absolute and a moderate variant of the principle. The "absolute" variant places a premium on the production of excellence above all else whilst the moderate version is a "mixed" conception that places the weight of excellence alongside other considerations. Essentially principles of perfection involve selection of certain types of lives as those which are given preference over others given their greater intrinsic value. Rawls terms this an "ideal-regarding" principle rather than a "want-regarding" principle. In one sense such a principle as that of perfection is close to Rawls' own endeavour since the principles of justice themselves are taken to have ideal requirements and to encourage certain types of character. But the principles of justice do not require reference to standards of excellence. 


Principles of perfection would not be adopted in the original position on Rawls' view as there is no shared standard of perfection given in the original position. There is only an index of primary goods, which are assumed to be something all would want, not a standard of excellence which only some would aspire to incarnating or aiming towards. Only if a natural duty was assumed in the original position that was accepted as culturally viable could there be space within it for the choice of the principle of perfection. This does not mean that all activities will be taken to be of equal value but that there is not an assumption that the attainment of particular types of excellence will shape the basic structure.


The principle of perfection, if combined with another in the moderate "mixed" version, faces the familiar problems Rawls always poses to intuitionist views. Generally Rawls also considers the appeal to "excellence" to involve considerations that are distinct from those of justice. So, for example, appeals for certain kinds of prohibitions on behaviour (as with sodomy statutes) often require that particular ways of life be given special privilege but this consideration, given as such, has no obvious claim to be a just one. As Rawls puts it, "subtle aesthetic preferences and personal feelings of propriety" shape standards of excellence and these types of preference are not obvious bases for just evaluations.


With the rejection of the principle of perfection in both absolute and moderate forms Rawls concludes Chapter V, a conclusion that effectively closes his consideration of how the principles of justice relate to institutions in a general sense although, as we shall see, in due course, one very important question of institutional type is left for discussion in Chapter VI.

Rawls and Common Sense Precepts of Justice

In my last posting on Rawls I discussed the form the two principles of justice reach in Chapter V of A Theory of Justice. Having stated this form I then wondered what justified the rest of the work, or at least, the rest of Chapter V. Chapter V is, in fact, subsequently, an argument concerning different views of justice to that articulated in the notion of justice as fairness. Two sections concern "common sense" precepts, one the notion of "mixed conceptions" of justice and a final one, the principle of perfection. In this posting I'm simply going to fix on the discussion of "common sense" precepts which is the main subject of sections 47 and 48 of Chapter V.


Section 47 opens with a reiteration of the point that the sketch of the system of institutions that satisfies the two principles of justice is now complete. Assuming the basic structure has this form the distribution that results will be just (or, minimally, not unjust) and the analogy here, as is typical of much of the argument of Theory, is with the outcome of a fair game. However, at this point, Rawls turns to consider the question of how the conception of justice as fairness relates to our common sense precepts of justice. 


Common sense precepts have within them the problem of priority that Rawls articulated back in Chapter I as arising for intuitionist conceptions and which the various arguments for priority of principles that he gave in the previous sections of Chapter V show a basis for having overcome on the conception of justice as fairness. The two principles of justice are taken to define the basic criterion of how we will understand justice but are themselves arranged in an hierarchical order and contain (in the case of the second principle) sub-parts that themselves need articulating in order.


Rawls now considers various types of "common sense" precept and how they arise. However, he is less interested in these precepts themselves than with how different conceptions of justice lead to different ways of weighing them. The difference between different conceptions of justice is not understood by Rawls to reside in different types of common sense precepts but, instead, in different types of attention to them. A society that provides for fair equality of opportunity (the first part of the second principle of justice) responds differently to common sense precepts once this principle is part of its basic structure than does another society that does not provide for fair equality of opportunity in this way.


For one thing the provision of opportunities according to this principle tends to produce greater levelling of incomes with the result that the precept of rewarding each according to training is given less weight in this society than in alternative ones that have not built the principle of fair equality of opportunity into their basic structure. What this example is meant to show is that the type of generality that common sense precepts possess is the wrong sort for the articulation of principles of justice. This is despite the fact that some common sense precepts do initially appear general enough, such as ones that stress the natural right of property in the fruits of our labour (a kind of Lockean view). However, for this view to really be generally applicable it must be the case that the distribution it refers to is part of a generally just order, it cannot simply define one. It is, after all, just one of many precepts with another, also often appealed to and clearly off-setting this, referring to distribution according to need.


In market situations the general problem, at work in the kind of Lockean conception, is one in which contributions are expected to be rewarded. But what matters for any given kind of contribution is the relation of it to the whole system of norms in question. In this respect the questions of choice of occupation and free association are parts of a system of justice but the overall principle of fair equality of opportunity is one that determines the rewards that would arise in relation to them.


If section 47 articulates the problem that common sense precepts lack sufficient generality to stand in for principles of justice at the level of the basic structure, section 48, by contrast, tackles one specific type of principle that would threaten to reduce questions of justice to questions of virtue. This would be the adoption of a general principle that rewards should be adjusted by connection to virtue or moral worth shown (a kind of "republic of virtue"). Justice as fairness is in opposition to such a notion despite recognising the place of legitimate expectations within systems of justice.


The extent of a contribution someone has made at a given time is often determined impersonally by mechanisms such as markets that price the reward of a given effort in ways that may have little connection to the individual effort involved. This is a problem with viewing the conception of just distributive shares as a process of maximising returns by reference to conscientious effort. It also shows the difficulty of adopting such a principle as a public one. Moral worth, whether defined through conscientious effort or in some other way, is not a principle of distributive justice. Indeed, so little is this the case according to Rawls that there would be something grossly offensive about thinking of justice in this way as he suggests in the following striking comparison: "For a society to organize itself with the aim of rewarding moral desert as a first principle would be like having the institution of property in order to punish thieves".


The reason for this striking analogy concerns the distinction Rawls draws between a conception of reward determined by virtue and one that draws on the correct notion of legitimate expectations. In the latter case the expectations are what arise from doing things encouraged by existing arrangements and these would be best defined, on Rawls' view, by reference to the principle of fairness and the natural duty of justice. Institutions are bound to realise legitimate expectations they have encouraged in relation to these superordinate principles of justice. However, even when we have a system of justice that is governed by such principles there is no way of ensuring that conscientious effort or any other such type of moral worth would lead to higher rewards.


In this respect distributive justice is quite unlike retributive justice. If the purpose of the latter is to uphold basic natural duties through the provision of penalties attached to their violation, the purpose of distributive justice is only to ensure a generally just order and to reward individuals for carrying out generally valued social functions, so the variations in rewards should only be concerned with promoting the general ends of the basic structure, not the elevation of particular individuals in a parallel to the degradation suffered by those who have violated natural duties.


In sum then, Rawls concludes that most common sense precepts of justice are insufficiently general to be possible candidates in the original position for the status of general principles of justice and he specifically rules out views that would conceive of social justice as a wide form of reward for virtue since the latter view conflates the purposes of distributive justice with those of retributive justice.
