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.

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.

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.

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.

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

The long republican tradition is characterized by a conception of freedom as non‐domination, which offers an alternative, both to the negative view of freedom as non‐interference and to the positive view of freedom as self‐mastery. The first part of the book traces the rise and decline of the conception, displays its many attractions and makes a case for why it should still be regarded as a central political ideal. The second part of the book looks at the sorts of political and civil institutions that would be required in a society in which freedom as non‐domination is systematically fostered. It outlines the causes and policies, the constitutional and democratic forms, and the regulatory controls that a republican state ought to endorse. And it argues for a vision of the state's relation to civil society in which there is no pretence of doing without widespread civility and trust; the argument is that the state ought, at once, to foster and build on such extra‐political foundations.

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

We have two ways of talking about liberty or freedom, one in the singular, the other in the plural. We concern ourselves in the singular mode with how far someone is free to do or not to do certain things, or with how far someone is a free person or not a free person. But, equally, we concern ourselves with the plural question as to how far the person enjoys the liberties that we take to be important or basic. What are those plural liberties, however? What does it take for something to count as a basic liberty? e usual approach to this question is to give a list of some presumptive basic liberties — say, those of thought, speech, and association — and then to add a gestural ‘and so on’. My aim in this paper is to do a little better in elaborating a conception of the sorts of liberties at which the ‘and so on’ gestures. I argue that the basic liberties can be usefully identifi ed as the liberties required for living the life of a free person or citizen and I spell out that requirement in three constraints, which I describe as feasible extension, personal signifi cance and equal co-enjoyment. ere are many candidate sets of basic liberties that might be proposed for protection, whether in general or for a particular society. e claim that I defend is that in order to count as a set of basic liberties, the types of choice protected under any proposal should be capable of being equally enjoyed at the same time by everyone (equal co-enj oyment), should be important in the life of normal human beings (personal signifi cance), and should not be unnecessarily restricted: they should be as extensive as the other constraints allow (feasible extension). e aim of the paper being quite limited, I abstract from many important issues. I do not provide an argument for why it is important that some set of basic liberties be protected, nor do I rate the importance of such protection against other social goals. I say nothing on how far it should be a requirement of democracy that certain sorts of liberties are entrenched—whether constitutionally or otherwise—and how far democratic process should be allowed to vary the specifi - cation and protection of basic liberties..

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

As the first ontologist, Parmenides has a special place in the history of philosophy, not only because of his originality, but also because of the greatness of his particular attempt in the philosophy of being. His stature is such that any later attempt in the inquiry into being must measure itself against his achievement. His famous philosophical poem, which we have in fragments, is a permanent challenge to later philosophers. Thus Plato could describe Parmenides as ‘a man to be respected and at the same time feared’. And in our own day Martin Heidegger has said that.
