While a large social-choice-theoretic literature discusses the aggregation of individual judgments into collective ones, there is much less formal work on the transformation of judgments in group communication. I develop a model of judgment transformation and prove a baseline impossibility theorem: Any judgment transformation function satisfying some initially plausible conditions is the identity function, under which no opinion change occurs. I identify escape routes from this impossibility and argue that the kind of group communication envisaged by deliberative democats must be (...) "holistic": It must focus on webs of connected propositions, not on one proposition at a time, which echoes the Duhem-Quine "holism thesis" on scientific theory testing. My approach provides a map of the logical space in which different possible group communication processes are located. (shrink)

The notion of a spontaneous social order, an order in human affairs which operates without the intervention of any directly ordering mind, has a natural fascination for social and political theorists. This paper provides a taxonomy under which there are two broadly contrasting sorts of spontaneous social order. One is the familiar invisible hand; the other is an arrangement that we describe as the intangible hand. The paper is designed to serve two main purposes. First, to provide a pure account (...) of the invisible hand, with some indication of the varieties of invisible hand (and, indeed, backhand) available. Second, to develop and motivate the unfamiliar conception of the intangible backhand. We believe that a recognition of the availability of this latter sort of spontaneous organising mechanism — and the mechanism is implicitly recognised in many traditions — is of great importance in political theory; it is of particular importance nowadays when the usual focus is entirely on the invisible hand.

The tenuous claims of cost-benefit analysis to guide policy so as to promote welfare turn on measuring welfare by preference satisfaction and taking willingness-to-pay to indicate preferences. Yet it is obvious that people's preferences are not always self-interested and that false beliefs may lead people to prefer what is worse for them even when people are self-interested. So welfare is not preference satisfaction, and hence it appears that cost-benefit analysis and welfare economics in general rely on a mistaken theory of (...) well-being. This essay explores the difficulties, criticizes standard defences of welfare economics, and then offers a new partial defence that maintains that welfare economics is independent of any philosophical theory of well-being. Welfare economics requires nothing more than anevidentialconnection between preference and welfare: in circumstances in which people are concerned with their own interests and reasonably good judges of what will serve their interests, their preferences will be reliable indicators of what is good for them.

Modern society is challenged by a loss of efficiency in national governance systems values, and lifestyles. Corporate social responsibility (CSR) discourse builds upon a conception of organizational legitimacy that does not appropriately reflect these changes. The problems arise from the a-political role of the corporation in the concepts of cognitive and pragmatic legitimacy, which are based on compliance to national law and on relatively homogeneous and stable societal expectations on the one hand and widely accepted rhetoric assuming that all members (...) of society benefit from capitalist production on the other. We therefore propose a fundamental shift to moral legitimacy, from an output and power oriented approach to an input related and discursive concept of legitimacy. This shift creates a new basis of legitimacy and involves organizations in processes of active justification vis-à-vis society rather than simply responding to the demands of powerful groups. We consider this a step towards the politicization of the corporation and attempt to re-embed the debate on corporate legitimacy into its broader context of political theory, while reflecting the recent turn from a liberal to a deliberative concept of democracy.

The aim of this paper is to consider whether some seats in a democratically elected legislative assembly ought to be reserved for representatives of future generations. In order to examine this question, I will propose a new democratic model for representing posterity. It is argued that this model has several advantages compared with a model for the democratic representation of future people previously suggested by Andrew Dobson. Nevertheless, the democratic model that I propose confronts at least two difficult problems. First, (...) it faces insoluble problems of representative legitimacy. Second, one might question whether this model provides a reasonably effective way to represent future interests compared with existing representative democratic institutions. Despite such problems, it is argued that political representation of posterity can be defended on the basis of fundamental ideas and ideals in recent theory of deliberative democracy. The first reason for this is that in a number of cases democratic decisions cannot be regarded as normatively legitimate from the point of view of deliberative democracy, unless posterity is given a voice. The second reason is that representation of posterity can contribute to more rational and impartial deliberations and decisions in legislative assemblies. (shrink)

Abstract:We present a model of collective decision making in which aggregation and deliberation are treated simultaneously. Individuals debate in a public forum and potentially revise their judgements in light of deliberation. Once this process is exhausted, a rule is applied to aggregate post-deliberation judgements in order to make a social choice. Restricting attention to three alternatives, we identify conditions under which a democracy is ‘truth-revealing’. This condition says that the deliberation path and the aggregation rule always lead to the correct (...) social choice being made, irrespective of both the original profile of judgements and the size of the electorate.

The paper deals with the mutual interest of both economic and social theory in exploring a broader concept of the rational and in finding validity claims for rational discourse. Efficiency and effectiveness are discussed as possible validity criteria in evaluating norms in practical discussion. In addition to the problem of defining validity criteria for argumentation on norms and social choices, a major difficulty arises from the lack of a legitimate reflective centre in society which could integrate behaviour with norms and (...) metapreferences. As ways of motivating cooperative, collective action, both norm commitment and self‐interest should be appealed to. (shrink)

Most applications of cost-benefit analysis in environmental policy, and almost all the controversial cases, involve the use of contingent valuation (CV) surveys. There is now a relatively well-developed critique of CV as a method of public consultation on environmental issues. Theories of deliberative democracy have been invoked which question the individualistic, preference-based calculus of CV. A particular deliberative institution which has recently received much attention is the citizens' jury (CJ). While CJs and other deliberative institutions have come to be regarded (...) as alternatives to CV, it is far from obvious in what sense this is true. The discussion begins by exploring the extent to which CV and CJ can be meaningfully compared. After specifying a limited sense in which this is possible, the paper goes on to assess the virtues of deliberation by reference to this comparison. Much of the assessment is made from the perspective of rational choice theory, because that approach has been influential amongst critics of deliberative democracy. The main aim is to develop an argument for the merits of deliberation, in terms which its critics must acknowledge. (shrink)

How does public discussion contribute to the reasonableness with which power is exercised in a democracy? Contemporary answers to this question (such as formulated by Rawls or Habermas), are often based upon two interconnected preconceptions. These are, 1. the idea that the value of public discussion lies primarily in the fact that citizens can reach a reasonable consensus through argumentation and discussion and, 2. the belief that the exercise of power is legitimate only if it is determined by a reasonable (...) consensus among citizens. In this sense, 'reasonable consensus among citizens' eliminates, under ideal conditions, the 'autonomy' of the exercise of power. However, these ideals of democracy appear to conflict with certain aspects of democratic society; aspects, moreover, which we tend to value quite highly. I therefore advance an alternative account of the reasonableness of power in democratic societies; one which acknowledges both the characteristically unlimited scope of public discussion in democratic society and the fact that such discussion rarely or perhaps even never ends in a general consensus. In order to elucidate the democratic character of society we must explain the relationship between discussion and power in such a way that we understand both the need for discussion and the necessity of an autonomous exercise of power.

This paper builds upon, but substantially revises, John Harsanyi's concept of ‘extended preferences’. An individual ‘history’ is a possible life that some person (a subject) might lead. Harsanyi supposes that a given spectator, formulating her ethical preferences, can rank histories by empathetic projection: putting herself ‘in the shoes’ of various subjects. Harsanyi then suggests that interpersonal comparisons be derived from the utility function representing spectators’ (supposedly common) ranking of history lotteries. Unfortunately, Harsanyi's proposal has various flaws, including some that have (...) hitherto escaped scholarly attention. In particular, it ignores the limits of personal identity. If the subject has welfare-relevant attributes that the spectator cannot acquire without changing who she is, full empathetic identification of the latter with the former becomes impossible. This paper proposes instead to usesympathyas the attitude on a spectator's part that allows us to make sense of her extended preferences. Sympathy – an attitude of care and concern – is a psychological state quite different from empathy. We should also allow for hetereogeneity in spectators’ extended preferences. Interpersonal comparisons emerge from a plurality of sympathetic spectators, not (as per Harsanyi) from a common empathetic ranking. (shrink)

J’arguerai ici que tout en repoussant d’une main une conception du changement social basé sur la sélection naturelle des pratiques sociales et des individus qui y participent, les théories normatives qui font appel à des modélisations des choix sociaux, qu’ils soient de nature économique, politique ou morale, en entretiennent potentiellement les conséquences. Plus précisément, j’arguerai que les modèles que l’on utilise encore le plus volontiers dans les sciences sociales, c’est-à-dire ceux de la théorie des jeux, de la théorie de la (...) décision ou de la négociation rationnelle, contribuent à répercuter, au plan normatif, les deux aspects — social et individuel — de la sélection naturelle. L’argument s’appuie sur une analyse de la théorie standard de l’utilité et montre que la conception de la rationalité maximisante définie dans ce cadre formel incorpore les exigences de la sélection à celles de la rationalité.I shall argue that though most theoreticians of social change firmly refuse normatively to endorse the natural selection of practices and individuals, they sometimes tacitly validate the consequences of such a conception of social change. More precisely, I shall argue that the formal apparatus still often used in social sciences — such as game theory, bargaining theory or decision theory — contribute to carrying on, at the normative level the social and individual aspects of natural selection. The argument rests on an analysis of what has come to be regarded the standard theory of utility and attempts to show that maximising rationality defined in that framework incorporates the requirement of the selection to those of rationality.

This article addresses the theoretical difficulty of justifying the use of penal coercion in circumstances of marked, unjustified social inequality. The intuitive belief behind the text is that in such a context—that of an indecent State—justifying penal coercion becomes very problematic, particularly when directed against the most disfavored members of society.

La théorie du choix social qui s'est développée durant les dernières décennies, notamment dans la ligne des travaux d'Arrow et de Sen , ne s'est pas seulement soldée par une série de résultats négatifs exprimés dans les théorèmes d'impossibilité d'Arrow, de Sen et d'autres; ses notions centrales ont aussi été utilisées de manière fort variée au point que cette théorie souffre aujourd'hui d'un déficit important qui se traduit par de multiples indéterminations conceptuelles.
