Readers of fictions sometimes resist taking certain kinds of claims to be true according to those fictions, even when they appear explicitly or follow from applying ordinary principles of interpretation. This "imaginative resistance" is often taken to be significant for a range of philosophical projects outside aesthetics, including giving us evidence about what is possible and what is impossible, as well as the limits of conceivability, or readers' normative commitments. I will argue that this phenomenon cannot do the theoretical work that has been asked of it. Resistance to taking things to be fictional is often best explained by unfamiliarity with kinds of fictions than any representational, normative, or cognitive limits. With training and experience, any understandable proposition can be made fictional and be taken to be fictional by readers. This requires a new understanding both of imaginative resistance, and what it might be able to tell us about topics like conceivability or the bounds of possibility.

Moral fictionalism is the doctrine that the moral claims we accept should be treated as convenient fictions. One standard kind of moral fictionalism maintains that many of the moral claims we ordinarily accept are in fact false, but these claims are still useful to produce and accept, despite this falsehood. Moral fictionalists claim they can recover many of the benefits of the use of moral concepts and moral language, without the theoretical costs incurred by rivals such as moral realism or traditional moral noncognitivism. These benefits might include social benefits, like being able to resolve conflict peacefully, or psychological benefits for individuals, like resisting temptations that would be harmful.

This paper discusses an infinite regress that looms behind a certain kind of historical explanation. The movement of one barbarian group is often explained by the movement of others, but those movements in turn call for an explanation. While their explanation can again be the movement of yet another group of barbarians, if this sort of explanation does not stop somewhere we are left with an infinite regress of barbarians. While that regress would be vicious, it cannot be accommodated by several general views about what viciousness in infinite regresses amounts to. This example is additional evidence that we should prefer a pluralist approach to infinite regresses.

In May 1999, David Lewis sent Timothy Williamson an intriguing letter about knowledge and vagueness. This paper has a brief discussion of Lewis on evidence, and a longer discussion of a distinctive theory of vagueness Lewis puts forward in this letter, one rather different from standard forms of supervaluationism. Lewis's theory enables him to provide distinctive responses to the challenges to supervaluationism famously offered in chapter 5 of Timothy Williamson's 1994 book Vagueness. However these responses bring out a number of very surprising features of Lewis's own view. The letter from Lewis itself is available on the blog of The Age of Metaphysical Revolution Project, University of Manchester.

Parties to a temporary marriage agree in advance that their marriage will only last for a fixed period of time unless renewed: that it will automatically expire after two years, for instance, or five, or twenty. This paper defends the claim that temporary marriages deserve state recognition. The main argument for this is an application of a principle of marriage equality. Some other arguments for are also canvassed, including an argument from religious freedom, and a number of arguments against recognition are also discussed. The paper also discusses the question of whether such “temporary marriages” are in fact a kind of marriage, and defends the claim that they are, or would be, genuinely marriages.

In this paper, I take up three tasks in turn. The first is to set out what Routley thought we should demand of an all-purpose universal logic, and some of his reasons for those demands. The second is to sketch Routley's own response to those demands. The third is to explore how else we could satisfy some of the theoretical demands Routley identified, if we are not to follow him in endorsing Routleyan Ultralogic as a foundational logic. As part of this third project, I articulate what seems to me a preferable way of going to respond to the challenges Routley correctly identifies: and while I doubt what I will have to say would have convinced Routley himself, I will try to show that the approach I prefer has several advantages over Routley's.

Liberals agree that free speech should be protected, where speech is understood broadly to include all forms of intentional communication, including actions and pictures, not merely the spoken or written word. A surprising view about free speech in some liberal and legal circles is that communications should be protected on free-speech grounds only if the communications are mentally mediated. By “mentally mediated communication” we mean speech which communicates its message in such a way that the message can be rationally evaluated by hearers, and causes the hearers to believe it, when it does, through the mechanism of those hearers employing their rational capacity to judge that it is correct. The mental-mediation or persuasion principle, as it is sometimes called, has some important legal and public policy implications. It has been applied to argue that certain forms of expression, despite being forms of speech or expression, lack even a prima facie claim to protection on free speech grounds. Our central aim is to show why the mental mediation principle is mistaken. Liberals should think that some speech which is not mentally mediated deserves protection for the very same reasons that speech which is mentally mediated is often thought to deserve protection.

There is a class of fictionalist strategies (the reflexive fictionalisms) which appear to suffer from a common problem: the problem that the entities which are supposedly fictional turn out, by the lights of the fictionalist theory itself, to exist. The appropriate solution is to reject so-called strong fictionalism in each case: that is, to reject the variety of fictionalism which takes appeal to the domain of fictional entities to provide an explanation or analysis of the operators or predicates with which the objects are systematically correlated.

Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological naturalism, and how naturalists view the role of science in ethics and metaethics. It discusses how naturalism interacts with the use of intuitions, using conceptual analysis, and reflective equilibrium methods. Finally, it discusses some ways using scientific investigation can make distinctive contributions to ethics and metaethics.

Unified theories of de se attitudes and de dicto attitudes, along the lines of David Lewis’s proposal, face a problem. Whether or not they are adequate for representing beliefs, they can misrepresent the content of many of our desires, which rank possible outcomes in which the agent with the desire does not exist. These desires are shown to play a role in the rational explanation of action, and recognising them is important in our understanding of ourselves. Lewis’s account of attitudes de dicto and de se is shown to be unsatisfactory, and the lessons learned are applied more broadly.

Many people are inclined to think that consequences of actions, or perhaps reasonably expected consequences of those actions, have moral weight. Firing off shotguns in crowded areas is typically wrong, at least in part, because of the people who get maimed and killed. Committed consequentialists think that consequences (either actual consequences, or expected consequences, or intended consequences, or reasonably expected consequences, or maybe some other different shade) are all that matters, morally speaking. Lying and stealing are wrong, when they are wrong, only because of the consequences they have – these may include direct consequences, such as the loss of property by another, or another’s hurt at being deceived, but also indirect consequences, such as setting a bad example or cultivating a disposition to lie or steal too easily that risks manifesting when the direct harm would be more serious. Consequentialists do not have to agree on much else – they may not agree what the morally relevant consequences are (Bentham thought they were a matter of pleasure and avoidance of pain, others may define a conception of human welfare, or preference satisfaction, or something else), they may disagree over whether there is one sort of consequence or many sorts that are relevant, and they can disagree about how the consequences matter. A maximiser thinks that as much as possible of the relevant consequences is morally important, others may think that beyond some point, consequences are indifferent, others may think that the average distribution of consequences across agents is what matters, or largely what matters, and so on.1..

As is well known, Aristotelian natural philosophy, and many other systems of natural philosophy since, have relied heavily on teleology and teleological causation. Somehow, the purpose or end of an obj ect can be used to predict and explain what that object does: once you know that the end of an acorn is to become an oak, and a few things about what sorts of circumstances are conducive to the attainment of this end, you can predict a lot about the sprouting of the acorn and the subsequent behaviour of the piece of vegetation that results. Once you know that a rock seeks to move towards the centre of the Earth, you gain some insight into why it falls when released, and why it deforms the carpet or foot that it lands on. Once you know that the rabbit seeks to preserve itself, you can predict it will run from the fox. And so on. There are at least three features of Aristotle’s teleology, and more generally of an Aristotelian frame of mind about teleology, that may induce suspicion. One is that an end can serve as a "cause": as well as the sort of causation we all recognize, efficient causation, there are other forms, one of which is teleological causation. However, this can look less odd if we think of causes as things that figure in "because" answers to "why" questions. Whether or not self-preservation, or the rabbit’s continued existence, or something similar, causes the rabbit to run, the reply "because it seeks to continue in existence" certainly makes sense as an answer, or part of an answer, to a question about why it ran from the fox. (At present we are only.

David Lewis’s work in the past few decades produced a powerful and thought-provoking system, and this collection of eleven essays represents state-of-the-art engagement with that system across a range of topics. The title would suggest that the papers would deal in particular with Lewis’s doctrine of Humean supervenience, the doctrine that all the contingent truths are ultimately determined by instantiations of fundamental categorical properties at points of space-time, and the spatiotemporal relationships between those instantiations: that everything in our world supervenes on “local, particular matters of fact.” It is a bold philosophical program, with a reductionist approach to our everyday theoretical commitments and a goal of explaining the connections between the mental and the physical, laws and regularities, causes and effects, and chances and their outcomes, all without “necessary connections between distinct existences.” It is a program that many philosophers believe deserves attention in detail, even if many would wish to dispute parts of the picture. Indeed, Lewis himself does not so much defend Humean supervenience outright as argue that it need not be given up on philosophical grounds —in principle the materials allowed by Lewis would be enough to enable the world to contain such things as minds, causation, people, and languages; and in principle, Lewis claims, his Humean world has everything needed for truths of counterfactual conditionals and statements of objective chances. Lewis leaves open the question of whether physics in fact delivers us such a sparse world, but he thought that the lessons of his in-principle defense of Humean supervenience would carry over to a system including whatever fundamental physical posits will be eventually settled upon by science.

_ Source: _Volume 10, Issue 3, pp 441 - 456 Several kinds of historical alternatives are distinguished. Different kinds of historical alternatives are valuable to the practice of history for different reasons. Important uses for historical alternatives include representing different sides of historical disputes; distributing chances of different outcomes over alternatives; and offering explanations of why various alternatives did _not_ in fact happen. Consideration of counterfactuals about what would have happened had things been different in particular ways plays particularly useful roles in reasoning about historical analogues of current conditions; reasoning about causal claims; and in evaluating historical explanations. When evaluating the role of alternative histories in historical thinking, we should keep in mind the uses of historical alternatives that go well beyond the long-term and specific scenarios that are the focus of so-called “counterfactual history”.

This article focuses on the main methods used in analytic metaphysics. It first considers five important sources of constraints on metaphysical theorizing: linguistic and conceptual analysis, consulting intuitions, employing the findings of science, respecting folk opinion, and applying theoretical virtues in metaphysical theory choice such as preferring simpler theories, or preferring more explanatory theories. It then examines the role of formal methods in metaphysics as well as the role of metaphysical communities, traditions, and the place of the history of metaphysics in contemporary work. It also discusses the issue of whether metaphysics should be seen as an enterprise that will yield knowledge of metaphysical matters or whether it should have more modest epistemic goals. Finally, it explores the question of how much of metaphysics is a priori.

Curry's paradox for "if.. then.." concerns the paradoxical features of sentences of the form "If this very sentence is true, then 2+2=5". Standard inference principles lead us to the conclusion that such conditionals have true consequents: so, for example, 2+2=5 after all. There has been a lot of technical work done on formal options for blocking Curry paradoxes while only compromising a little on the various central principles of logic and meaning that are under threat. Once we have a sense of the technical options, though, a philosophical choice remains. When dealing with puzzles in the logic of conditionals, a natural place to turn is independently motivated semantic theories of the behaviour of "if... then...". This paper argues that the closest-worlds approach outlined in Nolan 1997 offers a philosophically satisfying reason to deny conditional proof and so block the paradoxical Curry reasoning, and can give the verdict that standard Curry conditionals are false, along with related "contraction conditionals".

This paper builds on the system of David Lewis’s “Parts of Classes” to provide a foundation for mathematics that arguably requires not only no distinctively mathematical ideological commitments (in the sense of Quine), but also no distinctively mathematical ontological commitments. Provided only that there are enough individual atoms, the devices of plural quantification and mereology can be employed to simulate quantification over classes, while at the same time allowing all of the atoms (and most of their fusions with which we are concerned) to be individuals (that is, urelements of classes). The final section of the paper canvasses some reasons to be committed to the required ontology for other than mathematical reasons.
