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.

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.

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..

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

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.

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

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? Deliberative-democratic theory has not addressed this issue, and this is a problem. The discursive dilemma of my title--a generalisation of the doctrinal paradox from analytical jurisprudence--shows that the procedures distinguished can come apart. Thus deliberative democrats must make up their minds on where they stand in relation to the issue; they cannot sit on the fence. This paper is an attempt to address the issue and look at the grounds on which it may be resolved.
