Abstract: This article offers a logical, linguistic, and philosophical account of modern quantification theory. Contrasting the standard approach to quantifiers (according to which logical quantifiers are defined by enumeration) with the generalized approach (according to which quantifiers are defined systematically), the article begins with a brief history of standard quantifier theory and identifies some of its logical, linguistic, and philosophical strengths and weaknesses. It then proceeds to a brief history of generalized quantifier theory and explains how it overcomes the weaknesses of the standard theory. One of the main philosophical advantages of the generalized theory is its philosophically informative criterion of logicality. The paper describes the work done so far in this theory, highlights some of its central logical results, offers an overview of its main linguistic contributions, and discusses its philosophical significance.

Abstract: Conceptions of individual autonomy and of rational autonomy have played large parts in twentieth century moral philosophy, yet it is hard to see how either could be basic to morality. Kant's conception of autonomy is radically different. He predicated autonomy neither of individual selves nor of processes of choosing, but of principles of action. Principles of action are Kantianly autonomous only if they are law-like in form and could be universal in scope; they are heteronomous if, although law-like in form, they cannot have universal scope. Puzzles about claims linking morality, reason and autonomy are greatly reduced by recognising the distinctiveness of Kantian autonomy

Abstract: Probabilism is committed to two theses: 1) Opinion comes in degrees - call them degrees of belief, or credences. 2) The degrees of belief of a rational agent obey the probability calculus. Correspondingly, a natural way to argue for probabilism is: i) to give an account of what degrees of belief are, and then ii) to show that those things should be probabilities, on pain of irrationality. Most of the action in the literature concerns stage ii). Assuming that stage i) has been adequately discharged, various authors move on to stage ii) with varied and ingenious arguments. But an unsatisfactory response at stage i) clearly undermines any gains that might be accrued at stage ii) as far as probabilism is concerned: if those things are not degrees of belief, then it is irrelevant to probabilism whether they should be probabilities or not. In this paper, the authors scrutinize the state of play regarding stage i). We critically examine several of the leading accounts of degrees of belief: reducing them to corresponding betting behavior (de Finetti); measuring them by that behavior (Jeffrey); and analyzing them in terms of preferences and their role in decision-making more generally (Ramsey, Lewis, Maher). We argue that the accounts fail, and so they are unfit to subserve arguments for probabilism. We conclude more positively: "degree of belief" should be taken as a primitive concept that forms the basis of our best theory of rational belief and decision: probabilism.

Abstract: This article presents a Kantian alternative to the mainstream approach in ethics concerning the phenomena that are widely thought to require a category of the supererogatory. My view is that the phenomena do not require this category of imperfect duties. Elsewhere I have written on Kant on this topic; here I shift my focus away from interpretive issues and consider the pros and cons of the Kantian approach. What background assumptions would lean one to favour the Kantian approach and what sorts would lean one to favour the mainstream approach? I also consider the possibility that in institutional contexts, there is a need for the category of the supererogatory. Here, it seems, we do need to know what we really have to do and what is beyond the call of duty; in this context, however, duty is not the Kantian moral notion, but rather is pegged to particular roles, or to the needs of the institution or group or club of which one is a member. But even here, I argue, the notion of the supererogatory is not crucial.

Abstract: Various scientific theories stand in a reductive relation to each other. In a recent article, the authors argue that a generalized version of the Nagel-Schaffner model (GNS) is the right account of this relation. In this article, they present a Bayesian analysis of how GNS impacts on confirmation. They formalize the relation between the reducing and the reduced theory before and after the reduction using Bayesian networks, and thereby show that, post-reduction, the two theories are confirmatory of each other. They ask when a purported reduction should be accepted on epistemic grounds. To do so, they compare the prior and posterior probabilities of the conjunction of both theories before and after the reduction and ask how well each is confirmed by the available evidence

Introduction: Are Constructivism and Contractualism different, and if so how? Seemingly they are not wholly different, and certainly not incompatible, since some writers have described themselves as both. As a first shot one might suggest that contractualists ground ethical or political justification in agreement of some sort, whereas constructivists ground them in some conception of reason. This will not provide any neat separation of the two approaches to justification, since agreement may provide a basis for reasons, and reasoning a way of achieving agreement. In opening up these questions a bit further I shall consider some of the moves John Rawls and Tim Scanlon make in talking about their own methods of ethics, and in particular, some of the connections they draw between their methods and the scope of their accounts of ethical reasoning.

Summary: Analysis review article of recent work on the topic of paternalism. Discusses different ways in which the term is defined, reviews the debate between 'paternalists' and 'anti-paternalists', and presents soft paternalism.

Abstract: There has been some debate as to whether or not it is possible to keep a promise, and thus fulfil a duty, to supererogate. In this paper, I argue, in agreement with Jason Kawall, that such promises cannot be kept. However, I disagree with Kawall's diagnosis of the problem and provide an alternative account. In the first section, I examine the debate between Kawall and David Heyd, who rejects Kawall's claim that promises to supererogate cannot be kept. I disagree with Heyd's argument, as it fails to get to the heart of the problem Kawall articulates. Kawall's argument however fails to make clear the problem with promising to supererogate because his discussion relies on the plausibility of the following claim: that supererogatory actions cannot also fulfil obligations. I argue that this view is mistaken because there are clear examples of supererogatory actions that also fulfil obligations. In the final section, I give my alternative account of the problem, identifying exactly what is wrong with fulfilling a duty, and thus keeping a promise, to supererogate. My diagnosis emphasises the importance of identifying non-supererogatory actions when it comes to understanding the way in which supererogatory actions go above and beyond the call of duty.

Abstract: Description: This article is a short overview of philosophical and formal issues in the treatment and analysis of logical consequence. The purpose of the paper is to provide a brief introduction to the central issues surrounding two questions: (1) that of the nature of logical consequence and (2) that of the extension of logical consequence. It puts special emphasis in the role played by formal systems in the investigation of logical consequence.

Abstract: This paper examines the connection between model-theoretic truth and necessary truth. It is argued that though the model-theoretic truths of some standard languages are demonstrably "necessary" (in a precise sense), the widespread view of model-theoretic truth as providing a general guarantee of necessity is mistaken. Several arguments to the contrary are criticized.
