Are companies, churches, and states genuine agents? Or are they just collections of individuals that give a misleading impression of unity? This question is important, since the answer dictates how we should explain the behaviour of these entities and whether we should treat them as responsible and accountable on the model of individual agents. Group Agency offers a new approach to that question and is relevant, therefore, to a range of fields from philosophy to law, politics, and the social sciences. (...) Christian List and Philip Pettit argue that there really are group or corporate agents, over and above the individual agents who compose them, and that a proper approach to the social sciences, law, morality, and politics must take account of this fact. Unlike some earlier defences of group agency, their account is entirely unmysterious in character and, despite not being technically difficult, is grounded in cutting-edge work in social choice theory, economics, and philosophy.

Democracy is not naturally plausible. Why turn such important matters over to masses of people who have no expertise? Many theories of democracy answer by appealing to the intrinsic value of democratic procedure, leaving aside whether it makes good decisions. In Democratic Authority, David Estlund offers a groundbreaking alternative based on the idea that democratic authority and legitimacy must depend partly on democracy's tendency to make good decisions.Just as with verdicts in jury trials, Estlund argues, the authority and legitimacy of (...) a political decision does not depend on the particular decision being good or correct. But the "epistemic value" of the procedure--the degree to which it can generally be accepted as tending toward a good decision--is nevertheless crucial. Yet if good decisions were all that mattered, one might wonder why those who know best shouldn't simply rule.Estlund's theory--which he calls "epistemic proceduralism"--avoids epistocracy, or the rule of those who know. He argues that while some few people probably do know best, this can be used in political justification only if their expertise is acceptable from all reasonable points of view. If we seek the best epistemic arrangement in this respect, it will be recognizably democratic--with laws and policies actually authorized by the people subject to them. (shrink)

Liberalism without Perfection offers an introduction to the debate between liberal perfectionism and political liberalism. This book is a new account and defence of Rawlsian political liberalism, one of the most discussed, but widely misunderstood and criticized theories in contemporary political theory.

According to republican theory, we are free persons to the extent that we are protected and secured in the same fundamental choices, on the same public basis, as one another. But there is no public protection or security without a coercive state. Does this mean that any freedom we enjoy is a superficial good that presupposes a deeper, political form of subjection? Philip Pettit addresses this crucial question in On the People's Terms. He argues that state coercion will not involve (...) individual subjection or domination insofar as we enjoy an equally shared form of control over those in power. This claim may seem utopian but it is supported by a realistic model of the institutions that might establish such democratic control. Beginning with a fresh articulation of republican ideas, Pettit develops a highly original account of the rationale of democracy, breathing new life into democratic theory. (shrink)

In this innovative and important work, Gerald Gaus advances a revised and more realistic account of public reason liberalism, showing how, in the midst of fundamental disagreement about values and moral beliefs, we can achieve a moral and political order that treats all as free and equal moral persons. The first part of this work analyzes social morality as a system of authoritative moral rules. Drawing on an earlier generation of moral philosophers such as Kurt Baier and Peter Strawson as (...) well as current work in the social sciences, Gaus argues that our social morality is an evolved social fact, which is the necessary foundation of a mutually beneficial social order. The second part considers how this system of social moral authority can be justified to all moral persons. Drawing on the tools of game theory, social choice theory, experimental psychology and evolutionary theory, Gaus shows how a free society can secure a moral equilibrium that is endorsed by all, and how a just state respects, and develops, such an equilibrium.

This book examines the Condorcet Jury Theorem and how its assumptions can be applicable to the real world. It will use the theorem to assess various familiar political practices and alternative institutional arrangements, revealing how best to take advantage of the truth-tracking potential of majoritarian democracy.

This book advances a theory of personal, public and political justification. Drawing on current work in epistemology and cognitive psychology, the work develops a theory of personally justified belief. Building on this account, it advances an account of public justification that is more normative and less "populist" than that of "political liberals." Following the social contract theories of Hobbes, Locke and Kant, the work then argues that citizens have conclusive reason to appoint an umpire to resolve disputes arising from inconclusive (...) public justifications. The rule of law, liberal democracy and limited judicial review are defended as elements of a publicly justified umpiring procedure. (shrink)

Suppose that the members of a group each hold a rational set of judgments on some interconnected questions, and imagine that the group itself has to form a collective, rational set of judgments on those questions. How should it go about dealing with this task? We argue that the question raised is subject to a difficulty that has recently been noticed in discussion of the doctrinal paradox in jurisprudence. And we show that there is a general impossibility theorem that that (...) difficulty illustrates. Our paper describes this impossibility result and provides an exploration of its significance. The result naturally invites comparison with Kenneth Arrow's famous theorem (Arrow, 1963 and 1984; Sen, 1970) and we elaborate that comparison in a companion paper (List and Pettit, 2002). The paper is in four sections. The first section documents the need for various groups to aggregate its members' judgments; the second presents the discursive paradox; the third gives an informal statement of the more general impossibility result; the formal proof is presented in an appendix. The fourth section, finally, discusses some escape routes from that impossibility. (shrink)

Taken as a model for how groups should make collective judgments and decisions, the ideal of deliberative democracy is inherently ambiguous. Consider the idealised case where it is agreed on all sides that a certain conclusion should be endorsed if and only if certain premises are admitted. Does deliberative democracy recommend that members of the group debate the premises and then individually vote, in the light of that debate, on whether or not to support the conclusion? Or does it recommend (...) that members individually vote on the premises, and then let their commitment to the conclusion be settled by whether or not the group endorses the required premises? Deliberative-democratic theory has not addressed this issue, and this is a problem. The discursive dilemma of my title--a generalisation of the doctrinal paradox from analytical jurisprudence--shows that the procedures distinguished can come apart. Thus deliberative democrats must make up their minds on where they stand in relation to the issue; they cannot sit on the fence. This paper is an attempt to address the issue and look at the grounds on which it may be resolved. (shrink)

Revisioning macro-democratic processes in light of the processes and promise of micro-deliberation, Innovating Democracy provides an integrated perspective on democratic theory and practice after the deliberative turn.

Aggregating individuals’ consistent attitudes might produce inconsistent collective attitudes. Some groups therefore need the capacity to form attitudes that are irreducible to those of their members. Such groups, group-agent realists argue, are agents in control of their own attitude formation. In this paper, however, I show how group-agent realism overlooks the important fact that groups consist of strategically interacting agents. Only by eliminating group agency from our social explanations can we see how individuals vote strategically to gain control of their (...) groups and produce collective attitudes we cannot make sense of if we treat groups as agents.

Political theorists have offered many accounts of collective decision-making under pluralism. I discuss a key dimension on which such accounts differ: the importance assigned not only to the choices made but also to the reasons underlying those choices. On that dimension, different accounts lie in between two extremes. The ‘minimal liberal account’ holds that collective decisions should be made only on practical actions or policies and that underlying reasons should be kept private. The ‘comprehensive deliberative account’ stresses the importance of (...) giving reasons for collective decisions, where such reasons should also be collectively decided. I compare these two accounts on the basis of a formal model developed in the growing literature on the ‘discursive dilemma’ and ‘judgment aggregation’ and address several questions: What is the trade-off between the (minimal liberal) demand for reaching agreement on outcomes and the (comprehensive deliberative) demand for reason-giving? How large should the ‘sphere of public reason’ be? When do the decision procedures suggested by the two accounts agree and when not? How good are these procedures at truthtracking on factual matters? What strategic incentives do they generate for decision-makers? My discussion identifies what is at stake in the choice between minimal liberal and comprehensive deliberative accounts of collective decisionmaking, and sheds light not only on these two ideal-typical accounts themselves, but also on many characteristics that intermediate accounts share with them.

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Free Public Reason examines the idea of public justification, stressing its importance but also questioning the coherence of the concept itself. Although public justification is employed in the work of theorists such as John Rawls, Jeremy Waldron, Thomas Nagel, and others, it has received little attention on its own as a philosophical concept. In this book Fred D'Agostino shows that the concept is composed of various values, interests, and notions of the good, and that no ranking of these is possible. (...) The notion of public justification itself is thus shown to be contestable. In demonstrating this, D'Agostino undermines many current political theories that rely on this concept. Having broken down the foundations of public justification, D'Agostino then offers an alternative model of how a workable consensus on its meaning might be reached through the interactions of a community of interpreters or delegates at a constitutional convention.

The two most influential traditions of contemporary theorizing about democracy, social choice theory and deliberative democracy, are generally thought to be at loggerheads, in that the former demonstrates the impossibility, instability or meaninglessness of the rational collective outcomes sought by the latter. We argue that the two traditions can be reconciled. After expounding the central Arrow and Gibbard-Satterthwaite impossibility results, we reassess their implications, identifying the conditions under which meaningful democratic decision making is possible. We argue that deliberation can promote (...) these conditions, and hence that social choice theory suggests not that democratic decision making is impossible, but rather that democracy must have a deliberative aspect.

The revival of republicanism was meant to challenge the hegemony of liberalism in contemporary political theory on the grounds that liberals show insufficient concern with institutional protection against political misrule. This article challenges this view by showing how neorepublicanism, particularly on Philip Pettit’s formulation, demands no greater institutional protection than does political liberalism. By identifying neutrality between conceptions of the good as the constraint on institutional requirements that forces neorepublicanism into the liberal framework, the article shows that neutrality is what (...) neorepublicans must jettison to offer a tenable critique of liberalism. Only then can neorepublicans ensure greater protection against misrule by demanding that citizens participate more actively in politics. They can then also criticize liberalism for failing to appreciate the importance of such protection. (shrink)

Mainstream political liberalism holds that legal coercion is permissible only if it is based on reasons that all can share, access or accept. But these requirements are subject to well-known problems. I articulate and defend an intelligible reasons requirement as an alternative. An intelligible reason is a reason that all suitably idealized members of the public can see as a reason for the person who offers it according to that person’s own evaluative standards. It thereby permits reasons into public justification (...) that all cannot share, access, or accept, and so contrasts with standard approaches to public justification. The intelligible reasons requirement has two striking implications. First, it severs the connection between public justification and principles of deliberative restraint. Second, it pushes political liberals to appeal to other political processes to publicly justify law, specifically bargaining, adjudication, and social evolution. (shrink)

I drive a wedge between public deliberation and public justification, concepts tightly associated in public reason liberalism. Properly understood, the ideal of public justification imposes no restraint on citizen deliberation but requires that those who have a substantial impact on the use of coercive power, political officials, advance proposals each person has sufficient reason to accept. I formulate this idea as the Principle of Convergent Restraint and apply it to legislators to illustrate the general reorientation I propose for the public (...) reason project. (shrink)

I model sequential decisions over multiple interconnected propositions and investigate path-dependence in such decisions. The propositions and their interconnections are represented in propositional logic. A sequential decision process is path-dependent if its outcome depends on the order in which the propositions are considered. Assuming that earlier decisions constrain later ones, I prove three main results: First, certain rationality violations by the decision-making agent—individual or group—are necessary and sufficient for path-dependence. Second, under some conditions, path-dependence is unavoidable in decisions made by (...) groups. Third, path-dependence makes decisions vulnerable to strategic agenda setting and strategic voting. I also discuss escape routes from path-dependence. My results are relevant to discussions on collective consistency and reason-based decision-making, focusing not only on outcomes, but also on underlying reasons, beliefs, and constraints. (shrink)

The rationality of individual agents is secured for the most part by their make-up or design. Some agents, however – in particular, human beings – rely on the intentional exercise of thinking or reasoning in order to promote their rationality further; this is the activity that is classically exemplified in Rodin’s sculpture of Le Penseur. Do group agents have to rely on reasoning in order to maintain a rational profile? Recent results in the theory of judgment aggregation show that under (...) a range of plausible conditions they do. In a slogan: group agents are made, not born. (shrink)

Most political liberals argue that only rules, policies and institutions that are part of society’s basic structure need to be justified with so-called public reasons. Laws enacted outside this set are legitimate if and when public reasons can justify the procedure that selects them. I argue that this view is susceptible to known problems from social choice theory. However, there are resources within political liberalism that could address them. If the scope of public reason is extended beyond the basic structure (...) it could order people’s preferences in a way that circumvents the identified issues. (shrink)

Public reasoning is widely thought to be essential to democracy, but there is much disagreement about whether such deliberation should be constrained by a principle of public reason, which may seem to conflict with important democratic values. This paper denies that there is such a conflict, and argues that the distinctive contribution of public reason is to constitute a relationship of civic friendship in a diverse society. Acceptance of public reason would not work against mutual understanding, learning, or compromise, nor (...) does the principle involve any violation of political equality. The real threat to democracy is not public reason, but the framing of public reason by a presumption against state action. (shrink)

ABSTRACTThe idea of public reason requires that citizens in their public deliberation employ considerations stemming from a shared conception of justice. One worry is that public reason's content will be incomplete, in that it does not contain sufficient material for adequate public debate. Rawls has a way of expanding the content of public reason to address such concerns—by including in public reason all those things you and I say in our justification of the conception of justice. After arguing that this (...) strategy fails, a new way of expanding public reason's content is proposed. Instead of understanding the Supreme Court—which Rawls famously calls the “exemplar” of public reason—as an institution that appeals to exogenously determined public reasons, we should understand the judicial authority in a liberal democratic society as an endogenous fountain of public reason.

Expert reasoning is responsible for some of the most stunning human achievements, but also for some of the most disastrous decisions ever made. The argumentative theory of reasoning has proven very effective at explaining the pattern of reasoning’s successes and failures. In the present article, it is expanded to account for expert reasoning. The argumentative theory predicts that reasoning should display a strong confirmation bias. If argument quality is not sufficiently high in a domain, the confirmation bias will make experts (...) tap into their vast knowledge to defend whatever opinion they hold, with polarization and overconfidence as expected results. By contrast, experts should benefit even more from the power of group discussion to make the best of the confirmation bias—when they genuinely disagree that is, otherwise polarization is again likely to ensue. When experts interact with laymen other mechanisms can take the lead, in particular trust calibration and consistency checking. They can yield poor outcomes if experts do not have a sustained interaction with laymen, or if the laymen have strong opinions when they witness a debate between experts. Seeing reasoning as a mechanism of epistemic vigilance aimed at finding and evaluating arguments helps make better sense of expert reasoning performance, be it in individual ratiocination, in debates with other experts, or in interactions with laymen.
