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.

The case for secrecy in voting depends on the assumption that voters reliably vote for the political outcomes they want to prevail. No such assumption is valid. Accordingly, voting procedures should be designed to provide maximal incentive for voters to vote responsibly. Secret voting fails this test because citizens are protected from public scrutiny. Under open voting, citizens are publicly answerable for their electoral choices and will be encouraged thereby to vote in a discursively defensible manner. The possibility of bribery, intimidation or blackmail moderates this argument but such dangers will be avoidable in many contemporary societies without recourse to secrecy.

This authoritative collection of the seminal texts in post-war political philosophy has now been updated and expanded. Reprints key articles, mainly unabridged, touching upon the nature of the state, democracy, justice, rights, liberty, equality and oppression. Includes work from politics, law and economics, as well as from continental and analytic philosophy. Now includes thirteen additional texts, taking account of recent developments in the field and reflecting the most pressing concerns in international affairs. Can be used alongside A Companion to Contemporary Political Philosophy as the basis for a systematic introduction to the subject

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? Is deliberative democracy to enforce the discipline of reason at the individual level, as in the first possibility, or at the collective level, as in the second?

A generation of social theorists have argued that if free-rider considerations show that certain collective action predicaments are unresolvable under individual, rational choice – unresolvable under an arrangement where each is free to pursue their own relative advantage – then those considerations will equally show that the predicaments cannot be resolved by recourse to norms (Buchanan, 1975, p. 132; Heath, 1976, p. 30; Sober and Wilson, 1998, 156ff; Taylor, 1987, p. 144). If free-rider considerations explain why people do not spontaneously keep the streets clean, though they would each prefer unlittered streets, then those considerations will also explain why there is no effective norm against littering the streets.

In common-sense morality, certain special obligations loom large. These are duties which are laid upon agents, be they individuals or groups, in virtue of their distinctive identities, relationships or histories: because of who they are, how they are linked to others or what they have done in the past. The particularistic basis of these obligations means that no one but the agent in question is engaged by such a duty. It is that agent's alone.These special obligations include duties towards oneself, towards one's dependants and towards those to whom one has made certain commitments. In each case they prescribe partisan treatment. The beneficiary is to enjoy a benefit which may not be especially important in the global scheme of things, and which may even be obtained at the cost of others’ being deprived of benefits that are equally or more important in some cosmic sense.

Assuming that states will remain a permanent feature of our world, what is the ideal that we should hold out for the international order? An attractive proposal is that those peoples that are already organized under non-dominating, representative states should pursue a twin goal: first, arrange things so that they each enjoy the republican ideal of freedom as non-domination in relation to one another and to other multi-national and international agencies; and second, do everything possible and productive to facilitate the representation of less fortunate peoples in non-dominating states and to incorporate them in a non-dominating international order. This republican ideal stands midway between a utopian ideal of cosmopolitan justice and a sceptical ideal of non-intervention. The article explores its attractions and the broad institutional measures that it would support

The economic explanation of individual behaviour, even behaviour outside the traditional province of the market, projects a distinctively economic image on the minds of the agents involved. It suggests that, in regard to motivation and rationality, they conform to the profile of homo economicus. But this suggestion, by many lights, flies in the face of common sense; it conflicts with our ordinary assumptions about how we each feel and think in most situations, certainly most non-market situations, and about how that feeling and thought manifests itself in action. What, then, to conclude? That common sense is deeply in error on these matters? That, on the contrary, economics is in error—at least about non-market behaviour—and common sense sound? Or that some form of reconciliation is available between the two perspectives? This paper is an attempt to defend a conciliationist position.

Can groups be rational agents over and above their individual members? We argue that group agents are distinguished by their capacity to mimic the way in which individual agents act and that this capacity must “supervene” on the group members' contributions. But what is the nature of this supervenience relation? Focusing on group judgments, we argue that, for a group to be rational, its judgment on a particular proposition cannot generally be a function of the members' individual judgments on that proposition. Rather, it must be a function of their individual sets of judgments across many propositions. So knowing what the group members individually think about some proposition does not generally tell us how the group collectively adjudicates that proposition: the supervenience relation must be “setwise,” not “proposition‐wise.” Our account preserves the individualistic view that group agency is nothing mysterious but also suggests that a group agent may hold judgments that are not directly continuous with its members' corresponding individual judgments.

In order to vindicate rational-choice theory as a mode of explaining social patterns in general - social patterns beyond the narrow range of economic behaviour - we have to recognize the legitimacy of explaining the resilience of certain patterns of behaviour: that is, explaining, not necessarily why they emerged or have been sustained, but why they are robust and reliable. And once we allow the legitimacy of explaining resilience, then we can see how functionalist theory may also serve us well in social science; we lose the basis - the empty black box argumenton which the rational-choice critique of the theory has mostly been grounded
