• Limiting Logical Pluralism
    Synthese. forthcoming.
    In this paper I argue that pluralism at the level of logical systems requires a certain monism at the meta-logical level, and so, in a sense, there cannot be pluralism all the way down. The adequate alternative logical systems bottom out in a shared basic meta-logic, and as such, logical pluralism is limited. I argue that the content of this basic meta-logic must include the analogue of logical rules Modus Ponens (MP) and Universal Instantiation (UI). I show this through a detailed analysis of t…Read more
  • The Adoption Problem and Anti-Exceptionalism about Logic
    Australasian Journal of Logic. forthcoming.
    Anti-exceptionalism about logic takes logic to be, as the name suggests, unexceptional. Rather, in naturalist fashion, the anti-exceptionalist takes logic to be continuous with science, and considers logical theories to be adoptable and revisable accordingly. On the other hand, the Adoption Problem aims to show that there is something special about logic that sets it apart from scientific theories, such that it cannot be adopted in the way the anti-exceptionalist proposes. In this paper I assess…Read more
  • The Metaphysics of Surrogacy
    In David Boonin (ed.), The Palgrave Handbook of Philosophy and Public Policy, Springer International Publishing Ag. pp. 649-659. 2018.
    As with most other areas of reproduction, surrogacy is highly regulated. But the legislation and policies on surrogacy are written in such ways that make large (and possibly mistaken) assumptions about the metaphysical relationship between the mother and the fetus – whether the fetus is a part of, or contained by, the mother. It is the purpose of this chapter to highlight these assumptions, and to demonstrate the impact that alternative metaphysical views can have on our conceptualization of sur…Read more
  • Quantifier Variance Dissolved
    with Otávio Bueno
    Royal Institute of Philosophy Supplement 82 289-307. 2018.
    Quantifier variance faces a number of difficulties. In this paper we first formulate the view as holding that the meanings of the quantifiers may vary, and that languages using different quantifiers may be charitably translated into each other. We then object to the view on the basis of four claims: (i) quantifiers cannot vary their meaning extensionally by changing the domain of quantification; (ii) quantifiers cannot vary their meaning intensionally without collapsing into logical pluralism; (…Read more
  • Metametametaphysics and Dialetheism
    Australasian Journal of Logic 14 (1): 128-146. 2017.
    This paper reflects on metametaphysics and as such develops a metametameta-physical view: that quietist metametaphysics requires dialetheism, and in turn a paraconsistent logic. I demonstrate this using Carnap’s metametaphysical position in his 'Empiricism, Semantics and Ontology' as an example, with regard to how it exhibits self-reference and results in inconsistency. I show how applying Carnap’s position to itself produces a dilemma, both horns of which lead to a contradiction. Such inconsist…Read more
  • Dissolving Yablo’s Hostage Crisis: In Defence of Defiance
    Australasian Philosophical Review 1 (2): 184-188. 2017.
    Yablo suggests a ‘hostage crisis’ occurs when an unproblematic statement ϕ entails, and is therefore hostage to, a problematic statement ψ. Yablo proposes a technical solution to this kind of problem by diminishing ϕ to ϕ*, where ϕ* does not entail ψ and thus is not hostage to it. I argue that Yablo’s proposal is unnecessary because the original, undiminished ϕ does not in fact entail ψ. This is what Yablo calls a ‘defiant’ position. I defend defiance by arguing that ϕ and ψ are of different met…Read more
  • Scientific realism holds that the terms in our scientific theories refer and that we should believe in their existence. This presupposes a certain understanding of quantification, namely that it is ontologically committing, which I challenge in this paper. I argue that the ontological loading of the quantifiers is smuggled in through restricting the domains of quantification, without which it is clear to see that quantifiers are ontologically neutral. Once we remove domain restrictions, domains …Read more
  • Humean Supervenience Rebugged
    Philosophia 42 (4): 959-970. 2014.
    This paper is a response to Lewis’ ‘Humean Supervenience Debugged’ . Lewis was in the business of defending Humean Supervenience, and the project seemed successful until the case of chance. Lewis thus originally named chance the ‘big bad bug’ for Humean Supervenience until the aforementioned paper in which he claims victory. Here I argue that he was unsuccessful and that Humean Supervenience remains bugged by chance. I will show how this bug remains due to a misdiagnosis of where the problem lie…Read more
