Rational explanation, as I understand it here, is the sort of explanation we practise when we try to make intentional sense of a person’s attitudes and actions. We may postulate various obstacles to rationality in the course of offering such explanations but the point of the exercise is generally to present the individual as a more or less rational subject: as a subject who, within the constraints of the obstacles postulated - and they can be quite severe - displays a rational pattern of attitude - formation and decision-making.In this paper I want to draw attention to three distinct, and progressively more specific, aspects of such rational explanation. I do so, because I believe that they are not always prised apart sufficiently. The first aspect of rational explanation is that it is a programming variety of explanation, in a phrase that Frank Jackson and I introduced some years ago (Jackson and Pettit 1988). The second is, in another neologism (Pettit 1986), that it is a normalising kind of explanation. And the third is that it is a variety of interpretation: if you like, it is a hermeneutic form of explanation.

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.

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.

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 market is traditionally hailed as the very exemplar of a system under which people enjoy freedom, in particular the negative sort of freedom associated with liberal and libertarian thought: freedom as noninterference. But how does the market appear from the perspective of a rival conception of freedom (freedom as non-domination) that is linked with the Roman and neo-Roman tradition of republicanism? The republican conception of freedom argues for important normative constraints on property, exchange, and regulation, without supporting extremes to the effect that ‘property is theft’ or ‘taxation is theft’ or anything of that kind. It does not cast a cold eye on commerce; it merely provides an alternative view of the attractions

Examines what is necessary for a group to constitute an agent that can display akrasia, and what steps such a group might take to establish self‐control. The topic has some interest in itself, and the discussion suggests some lessons about how we should think of akrasia in the individual as well as in the collective case. Under the image that the lessons support, akrasia is a sort of constitutional disorder: a failure to achieve a unity projected in the avowal of agency. This image fits well with the constitutional model of the soul in Plato's Republic.

Philip Pettit has drawn together here a series of interconnected essays on three subjects to which he has made notable contributions. The first part of the book discusses the rule-following character of thought. The second considers how choice can be responsive to different sorts of factors, while still being under the control of thought and the reasons that thought marshals. The third examines the implications of this view of choice and rationality for the normative regulation of social behaviour. Rules, Reasons, and Norms makes original and illuminating connections across a large swathe of territory, from metaphysics to philosophical psychology to the theory of rational regulation

How sensitive should you be to the testimony of others? You saw the car that caused an accident going through traffic lights on the red; or so you thought. Should you revise your belief on discovering that the majority of bystanders, equally well-equipped, equally well-positioned and equally impartial, reported that it went through on the green? Or take another case. You believe that intelligent design is the best explanation for the order of the living universe. Should you revise that belief on finding that most other people, or at least most who by your own lights are as intelligent, informed and impartial as yourself, believe that evolutionary theory offers the better account? Should you do this, in particular, if your own personal sense of where the evidence points – like your own vivid memory of the car going through on the red – remains firmly on the side of intelligent design? Assume, to take a third case, that there is a matter of fact about whether abortion is right or wrong. You believe that it is wrong, having a firm picture of it as an act on a par with murder. Should you revise that belief on discovering that among those whom you regard as equally intelligent, informed and impartial, most believe that abortion is not wrong, or at least not wrong in the way that murder is wrong? Should you do this, in particular, if your own personal sense of abortion remains unchanged; it still seems to you to be a grievous wrong? Should you put aside your own sense of things as mistaken, in the way you might put aside your imagined memory of the car going through on the red, and decide to go along with the majority view?

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.
