In a recent discussion of Amartya Sen's concept of the capabilities of people for functioning in their society – and the idea of targeting people's functioning capabilities in evaluating the society – G. A. Cohen accuses Sen of espousing an inappropriate, ‘athletic’ image of the person (Cohen, 1993, pp. 24–5). The idea is that if Sen's formulations are to be taken at face value, then life is valuable only so far as people actively choose most facets of their existence: if they fare well in the material stakes, for example, they must fare well as a result of active choice and effort, not because anyone else looks after them. ‘That’, says Cohen, ‘overestimates the place of freedom and activity in well-being’ (p. 25).

Trusting someone in an intuitive, rich sense of the term involves not just relying on that person, but manifesting reliance on them in the expectation that this manifestation of reliance will increase their reason and motive to prove reliable. Can trust between people be formed on the basis of Internet contact alone? Forming the required expectation in regard to another person, and so trusting them on some matter, may be due to believing that they are trustworthy; to believing that they seek esteem and will be rationally responsive to the good opinion communicated or promised by an act of trust; or to both factors at once. Neither mechanism can rationally command confidence, however, in the case where people are related only via the Internet. On the Internet everyone wears the ring of Gyges; everyone is invisible, in their personal identity, to others

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 problem which motivates this paper bears on the relationship between Marxism and morality. It is not the well-established question of whether the Marxist's commitments undermine an attachment to ethical standards, but the more neglected query as to whether they allow the espousal of political ideals. The study and assessment of political ideals is pursued nowadays under the title of theory of justice, the aim of such theory being to provide a criterion for distinguishing just patterns of social organization from unjust ones. The main rivals in the field represent justice respectively as legitimacy, welfare and fairness. Marxism does not put forward a distinctive conception of justice itself and the question is whether the Marxist is free to choose as he thinks fit among the candidates on offer.

If an agent is to be moved to action, then two requirements have to be fulfilled: first, the agent must possess beliefs about the way things actually are, about the actions possible given the way things are, and about the likely effects of those actions on how things are; and, second, the agent must have or form desires to change the way things are by resorting to this or that course of action. The beliefs tell the agent about how things are and about how they can be altered; the desires attract the agent to how things are not but can be made to be.

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

Modal functionalism is the view that talk about possible worlds should be construed as talk about fictional objects. The version of modal fictionalism originally presented by Gideon Rosen adopted a simple prefixing strategy for fictionalising possible worlds analyses of modal propositions. However, Stuart Brock and Rosen himself in a later article have independently advanced an objection that shows that the prefixing strategy cannot serve fictionalist purposes. In this paper we defend fictionalism about possible worlds by showing that there are other strategies besides the prefixing strategy for fictionalising talk about possible worlds, and that these strategies are proof against the objection advanced by Brock and Rosen

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..
