Abstract:

Vetter's Potentiality is an exposition and development of a new account of possibility and necessity, given in terms of potentialities. In this critical notice, I give an outline of some of the key claims of the book. I then raise some issues for the extent to which Vetter's view can accommodate genuine de re modalities, especially those of possible existence and non-existence. 

Summary: Defends an account of mathematical knowledge in which mathematical knowledge is a kind of modal knowledge. Leng argues that nominalists should take mathematical knowledge to consist in knowledge of the consistency of mathematical axiomatic systems, and knowledge of what necessarily follows from those axioms. She defends this view against objections that modal knowledge requires knowledge of abstract objects, and argues that we should understand possibility and necessity in a primative way.

Abstract:

Are there ever good epistemic reasons to neglect base rates? Assuming an empiricist modal epistemology, I argue that we face an interesting tension between some very plausible epistemic norms: a norm requiring us to proportion our beliefs to the evidence may facilitate knowledge of the actual world, whilst inhibiting our acquisition of modal knowledge—knowledge of how things could be, but are not. The potential for this tension in our epistemic norms is a significant result in its own right. It can also rationalize certain forms of demographic base-rate neglect.

Abstract: David Lewis famously argued that the time traveller ‘can’ murder her grandfather, even though she never will: it is compossible with a particular set of facts including her motive, opportunity and skill (1976: 150). I argue that while ordinary agents ‘can’ under Lewis’s conception, philosophers cannot – the latter will not only fail to fulfill their homicidal intentions but also fail to form them in the first place.

Publisher's Note: Traditionally, philosophers of quantum mechanics have addressed exceedingly simple systems: a pair of electrons in an entangled state, or an atom and a cat in Dr. Schrodinger's diabolical device. But recently, much more complicated systems, such as quantum fields and the infinite systems at the thermodynamic limit of quantum statistical mechanics, have attracted, and repaid, philosophical attention. Interpreting Quantum Theories has three entangled aims. The first is to guide those familiar with the philosophy of ordinary QM into the philosophy of 'QM infinity', by presenting accessible introductions to relevant technical notions and the foundational questions they frame. The second aim is to develop and defend answers to some of those questions. Does quantum field theory demand or deserve a particle ontology? How (if at all) are different states of broken symmetry different? And what is the proper role of idealizations in working physics? The third aim is to highlight ties between the foundational investigation of QM infinity and philosophy more broadly construed, in particular by using the interpretive problems discussed to motivate new ways to think about the nature of physical possibility and the problem of scientific realism.

Abstract: Description: Survey article on logical pluralism. The article is divided into three main parts: i) in the first one the author presents the main arguments for logical pluralism with respect to logical consequence; ii) in the second part, the author considers the relation between logical pluralism and Carnap's linguistic pluralism; iii) in the last section, the author considers further kinds of logical pluralism.

Abstract: This paper describes motivations for the view that some objects have essential properties: properties which they must have in any world/situation where they exist (without qualification). I raise objections to the motivations for so-called ``hardcore essentialism''. And I articulate and defend an alternative theory: explanation-relative essentialism.

Introduction: It is not easy to say what metaphysics is. Ancient and Medieval philosophers might have said that metaphysics was, like chemistry or astrology, to be defined by its subject matter: metaphysics was the 'science' that studied 'being as such' or 'the first causes of things' or 'things that do not change'. It is no longer possible to define metaphysics that way. First, a philosopher who denied the existence of those things that had once been seen as constituting the subject-matter of metaphysics - first causes or unchanging things - would now be considered to be making thereby a metaphysical assertion. Second, there are many philosophical problems that are now considered to be metaphysical problems (or at least partly metaphysical problems) that are in no way related to first causes or unchanging things - the problem of free will, for example, or the problem of the mental and the physical. The first three sections of this entry examine a broad selection of problems considered to be metaphysical and discuss ways in which the purview of metaphysics has expanded over time. The central problems of metaphysics were significantly more unified in the Ancient and Medieval eras. Which raises a question - is there any common feature that unites the problems of contemporary metaphysics? The final two sections of the entry discuss some recent theories of the nature and methodology of metaphysics, including those that consider metaphysics as an impossible enterprise.

Abstract:

Abstract: The Explanatory Gap' is a label for the idea that we cannot explain consciousness in terms of brain activity. There are many different formulations of the explanatory gap, but all discussion about it assumes that there is only one gap, which consists of the absence of a deductive explanation. This assumption is mistaken. In this paper, I show that the position that deductive explanation is privileged in this case is unmotivated. I argue that whether or not there is an explanatory gap depends on the kind of explanation in question, so there is no single, unified explanatory gap but only the absence and (perhaps) presence of different sorts of explanation.

Publisher’s Note:

Philosophical theories often hinge on claims about what is necessary or possible. But what are possibilities and necessities, and how could we come to know about them? This book aims to help demystify the methodology of philosophy, by treating such claims not as attempted descriptions of strange facts or distant 'possible worlds', but rather as ways of expressing rules or norms.

Summary: In this paper, Vetter looks at the argument for Dispositional Essentialism (DE) that has been put forward by A. Bird in his recent book Nature's Metaphysics. Bird's overall argument comes in two parts, one negative and one positive, which together are to establish DE as the best contender for a theory of properties and laws. Vetter argues that, even if all their particular steps go through, both parts of the argument have significant gaps. The negative argument, if successful, shows that at least one property has an essence, but not that any property has a dispositional essence. The positive argument, which aims to demonstrate the explanatory power of DE, fails to take account of the quantitative nature of the fundamental natural properties and laws. The paper finishes by suggesting a revision of DE's doctrine that might solve the latter problem, but yet remains to be spelled out.

Abstract: Dispositions are modal properties. The standard conception of dispositions holds that each disposition is individuated by its stimulus condition(s) and its manifestation(s), and that their modality is best captured by some conditional construction that relates stimulus to manifestation as antecedent to consequent. In this paper Vetter proposes an alternative conception of dispositions: each disposition is individuated by its manifestation alone, and its modality is closest to that of possibility - a fragile vase, for instance, is one that can break easily. The view is expounded in some detail and defended against the major objections.

Publisher's Note: This book develops and defends dispositionalism about modality: the view that metaphysical modality is a matter of the dispositions that objects have. Dispositionalism is an attractive view for actualists about modality, and for anyone who embraces an anti-Humean metaphysics of powers. This book shows in detail how such a view is to be formulated, which challenges it faces, and how they may be met. The metaphysics of potentiality is examined in detail to show that the view meets the three main challenges for a metaphysics of modality: (1) Extensional correctness: providing the right truth-values for statements of possibility and necessity; (2) formal adequacy: providing the right logic for metaphysical modality; and (3) semantic utility: providing a semantics that links ordinary modal language to the metaphysics of modality.
