This essay outlines some of the main issues that arise in the theory of freedom and, in particular, those that divide the liberal conception of freedom as non-interference from the republican conception of freedom as non-domination. It goes on to explore the idea that discourse theory provides reasons for favouring the republican conception. Discourse theory is taken for these purposes to be a theory that subsumes, but goes beyond decision theory. It accepts the decision-theoretic view that human agents are moved by beliefs and desires that, on the whole, are rationally maintained and rationally issued in action. But it adds the further, crucial assumption that human beliefs and desires are shaped under the transformative influence of discursive argument and exchange

Allan Gibbard’s strategy in his new book is to begin by describing a psychology of thinking and planning that certain agents might instantiate, then to argue that this psychology involves an ‘expressivism’ about thought that bears on what to do, and, finally, to try to show that ascribing that same psychology to human beings would explain the way we deploy various concepts in practical and normative deliberation. The idea is to construct an imaginary normative psychology, purportedly conforming to expressivist specifications, and then to campaign for the hypothesis that that psychology is ours and that we ourselves conform to those specifications. The upshot is an original and intriguing argument for the claim that ‘expressivism’, as Gibbard understands it, is sound. There is more in the book than that bare argument. Filling out the strategy pursued, for example, the volume contains useful discussions of a number of current debates (chs 2, 12), an enlightening argument that the strategy survives the introduction of the notion that a concept can have a character distinct from its content (ch. 6), and an extended set of reflections on how far the point of view defended leaves room for the idea of gaining normative knowledge (pt. 4). But I shall ignore those aspects of the book in this commentary; the focus is on its central argument. My approach will be to reconstuct the main stages in the Aufbau of our normative psychology that Gibbard provides, emphasizing some crucial points that are passed over rather quickly, and then to suggest on the basis of this reconstruction that the more natural lesson to derive is not an expressivist one. Although I break with Gibbard in that way, however, I have great admiration for the book. Thinking How to Live is a sharp, fresh and invigorating treatment of the main issues of metaethics

This book is in three sections, with two chapters in each. It begins with questions of psychology: questions to do with what it means to be an intentional agent and, in particular, what it means to be an agent with the capacity for thought. Having sketched an overall view of the intentional, thinking agent, it then goes on to explore the difference that social life makes to the mentality of such agents; in effect, it outlines a social ontology. And, having developed a picture of the mind in society – of the common or social mind – it turns, finally, to the lessons of this picture for the pursuit of social and political theory: for the explanation of what happens on the social scene and for the evaluation of the different ways in which that scene may be structured.

Imagine a very fi ne grid or graph on which dots are placed at various coordinates so that, as a consequence, this or that shape materializes there. Depending on the coordinates of the dots, different shapes will appear, and for every shape there will be a pattern in the coordinates that guarantees its appearance. Take, for example, the diagonal line that slopes rightward and upward at an angle of 45 degrees from the origin. This line is bound to make an appearance so long as the coordinates satisfy the condition or pattern that as they move away from the origin, (0,0), the coordinates are progressively larger pairs of equal numbers: (1,1), (3,3), and so on. In the world of such dots and shapes, it is going to be in principle possible, for any array of dots that realizes a relevant shape, to derive the presence of the shape from the numerical coordinates of the dots. More particularly, it is going to be possible to derive that shape without reliance on anything other than, fi rst, the empirical fact that the given array of coordinates instantiates this or that pattern; and second, the a priori knowable fact that the pattern guarantees the presence of the shape in question. The nature of the shapes on any grid—if indeed there are any relevant shapes present—is going to be a priori derivable from the positions of the dots; it is going to be possible in principle to derive the one from the other. The simplest and most appealing version of physicalism parallels this sort of doctrine about dots and shapes (Pettit 1994, 1995). It holds that just as the positions of the dots determine the nature of the shapes a priori, so the way the natural world is physically organized a priori determines the way it presents itself in psychological and other terms. The way things are physically confi gured entails the presence of psychological and other realities, and it does this without reliance on anything other than what a..

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.

Si les non-conséquentialistes veulent adhérer à l'exigence d'universalisabilité, alors ils devront adopter une prise de position étonnamment relativiste. Non seulement vont-ils affirmer, dans une veine familière, que les prémisses invoquées dans l'argumentation morale n'ont de force que relative à l'agent, c'est-à-dire qu'elles peuvent impliquer l'usage d'un indexical — comme dans la considération que cette option-ci ou celle-là favoriserait mes engagements, me délesterait de mes devoirs ou bénéficierait à mes enfants — et qu'elles ne peuvent fournir de raisons qu'à l'agent indexicalement pertinent, moi-même en l'occurrence. Ils devront aussi interpréter la considération invoquée dans les conclusions morales typiques, selon laquelle telle ou telle option est juste ou devrait être choisie ou peu importe, comme n'ayant elle-même qu'une force relative à l'agent.If non-consequentialists are to embrace the requirement of universalisability, then they will have to strike a surprisingly relativistic stance. Not only will they say, in familiar vein, that the premises adduced in moral argument may only be agent-relative in force: that is, may involve the use of an indexical — as in the consideration that this or that option would advance my commitments, discharge my duty, or benefit my children — and may provide reasons only for the indexically relevant agent: in this case, me. They will also have to construe the consideration adduced in typical moral conclusions, to the effect that this or that option is right or ought to be chosen or whatever, as itself only agent-relative in force
