The paper discusses two problems with Graham Priest’s version of dialetheism: the thesis that one cannot be rationally obliged to both accept and reject something, and the use of a Contraction-less conditional in dealing with Curry paradoxes. Some solutions are suggested.
Logical Pluralism from a Pragmatic Perspective
This paper presents a new view of logical pluralism. This pluralism takes into account how the logical connectives shift, depending on the context in which they occur. Using the Question-Under-Discussion Framework as formulated by Craige Roberts, I identify the contextual factor that is responsible for this shift. I then provide an account of the meanings of the logical connectives which can accommodate this factor. Finally, I suggest that this new pluralism has a certain Carnapian flavour. Questions about the meanings of the connectives or the best logic outside of a specified context are not legitimate questions.
Metalinguistic Negotiation and Logical Pluralism
Logical pluralism is the view that there is more than one right logic. A particular version of the view, what is sometimes called domain-specific logical pluralism, has it that the right logic and connectives depend somehow on the domain of use, or context of use, or the linguistic framework. This type of view has a problem with cross-framework communication, though: it seems that all such communication turns into merely verbal disputes. If two people approach the same domain with different logics as their guide, then they may be using different connectives, and hence talking past each other. In this situation, if we think we are having a conversation about “ ¬ A”, but are using different “ ¬ ”s, then we are not really talking about the same thing. The communication problem prevents legitimate disagreements about logic, which is a bad result. In this paper I articulate a possible solution to this problem, without giving up pluralism, which requires adopting a notion of metalinguistic negotiation, and allows people to communicate and disagree across domains/contexts/frameworks.
Potentiality
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.
How to Water a Thousand Flowers. On the Logic of Logical Pluralism
How many logics do logical pluralists adopt, or are allowed to adopt, or ought to adopt, in arguing for their view? These metatheoretical questions lurk behind much of the discussion on logical pluralism, and have a direct bearing on normative issues concerning the choice of a correct logic and the characterization of valid reasoning. Still, they commonly receive just swift answers – if any. Our
aim is to tackle these questions head on, by clarifying the range of possibilities that logical pluralists have at their disposal when it comes to the metatheory of their position, and by spelling out which routes are advisable. We explore ramifications of all relevant responses to our question: no logic, a single logic, more than one logic. In the end, we express skepticism that any proposed answer is viable. This threatens the coherence of current and future versions of logical pluralism.
Ruth Barcan Marcus and quantified modal logic
Analytic philosophy in the mid-twentieth century underwent a major change of direction when a prior consensus in favour of extensionalism and descriptivism made way for approaches using direct reference, the necessity of identity, and modal logic. All three were first defended, in the analytic tradition, by one woman, Ruth Barcan Marcus. But analytic philosophers now tend to credit them to Kripke, or Kripke and Carnap. I argue that seeing Barcan Marcus in her historical context – one dominated by extensionalism and descriptivism – allows us to see how revolutionary she was, in her work and influence on others. I focus on her debate with Quine, who found himself retreating to softened, and more viable, versions of his anti-modal arguments as a result. I make the case that Barcan’s formal logic was philosophically well-motivated, connected to her views on reference, and well-matched to her overall views on ontology. Her nominalism led her to reject posits which could not be directly observed and named, such as possibilia. She conceived of modal calculi as facilitating counterfactual discourse about actual existents. I conclude that her contributions ought to be recognized as the first of their kind. Barcan Marcus must be awarded a central place in the canon of analytic philosophy.
Symmetry and Hybrid Contingentism
This paper outlines a defense of hybrid contingentism: that it is contingent which individuals there are, but not contingent what properties there are. Critics pursue two main lines of complaint. First, that the hybrid contingentist’s treatment of haecceitistic properties is metaphysically mysterious, and second, that hybrid contingentism involves an unjustified asymmetry in the associated modal logic. I suggest that these complaints may be too quick, at least in the setting of higher-order metaphysics. It is not at all obvious whether and to what extent we should expect particular “symmetries” across the orders, and so whether (as Williamson (2013) argues) “the default preference is for a uniform metaphysics, on which being is contingent at all orders or none.”
Environmental Virtue Aesthetics
How should we characterize the interaction between moral and aesthetic values in the context of
environmental aesthetics? This question is important given the urgency of many environmental
problems and the particular role played by aesthetic value in our experience of environment. To
address this question, we develop a model of Environmental Virtue Aesthetics (EVA) that, we argue,
offers a promising alternative to current theories in environmental aesthetics with respect to the
relationship between aesthetics and ethics. EVA counters environmental aesthetic theories that focus
more narrowly on scientific knowledge and ground aesthetic value in ways that obfuscate pluralistic
modes of appreciation of and relationships with natural and semi-natural environments. To develop
EVA, we work with a revised notion of respect and engage with ideas concerning the development of
aesthetic sensibilities, care, and virtuous aesthetic appreciation. EVA has the potential to support
forms of human-nature co-flourishing, as well as constituting an aesthetic grounding for ecological
citizenship.
‘But it’s your job!’ The moral status of jobs and the dilemma of occupational duties
Do individuals have moral duties to fulfil all the demands of their jobs? In this paper, we discuss how to understand such ‘occupational duties’ and their normative bases, with a specific focus on duties that go beyond contractually agreed upon duties. Against views that reduce occupational duties to contractual duties, we argue that they often have greater moral weight, based on skills, roles, and the duty of social cooperation. We discuss what it would take to make sure that individuals are not unfairly overburdened by such occupational duties, distinguishing between choice conditions (voluntariness, availability of alternatives, full information) and conditions concerning the role and the social structures within which such duties are embedded (feasible role design, existence of support structures, employee voice). These conditions, however, are not fulfilled for many existing jobs, especially for jobs typically occupied by structurally disadvantaged groups such as women or ethnic minorities. This leads to a dilemma between the claims of those who depend on the occupational duties to be fulfilled, and the rights of those who hold these occupations and are unfairly overburdened. We conclude by arguing for the need for structural reform to dissolve this dilemma.
What a Home Does
Analytic philosophy has largely neglected the topic of homelessness.
The few notable exceptions, including work by Jeremy Waldron and Christopher
Essert, focus on our interests in shelter, housing, and property rights, but ignore the
key social functions that a home performs as a place in which we are welcomed,
accepted, and respected. This paper identifies a ladder of home-related concepts
which begins with the minimal notion of temporary shelter, then moves to persistent
shelter and housing, and finally to the rich notion of a home which focuses on meeting
our social needs including, specifically, our needs to belong and to have meaningful
control over our social environment. This concept-ladder enables us to distinguish
the shelterless from the sheltered; the unhoused from the housed; and the unhomed
from the homed. It also enables us to decouple the concept of a home from property
rights, which reveals potential complications in people’s living arrangements. For
instance, a person could be sheltered but unhoused, housed but homeless, or, indeed,
unhoused but homed. We show that we should reserve the concept of home to
capture the rich idea of a place of belonging in which our core social needs are met.
