This chapter develops a theory of metaphysical indeterminacy. It construes indeterminacy as a metaphysical primitive and contrasts this approach to more familiar (semantic or epistemic) accounts of indeterminacy. It argues that there is no conceptual barrier to understanding indeterminacy along these lines. It then shows how indeterminacy (taken as a metaphysical primitive) can be explicated using familiar modal resources. Using this modal framework as a basis, the chapter develops a logic for metaphysical indeterminacy that is fully classical and bivalent. Developing this logic allows for the evaluation of key issues concerning indeterminacy, including higher-order indeterminacy, the interaction of indeterminacy and possibility, and de re indeterminacy.

In this paper, I argue that whether, how, and to what extent an experience is transformative is often highly contingent. I then further argue that sometimes social conditions are a major factor in whether a certain type of experience is often or typically transformative. Sometimes social conditions make it easy for a type of experience to be transformative, and sometimes they make it hard for a type of experience to be transformative. This, I claim, can sometimes be a matter of social justice: social conditions can make transformativeness too easy or too hard, in a way that harms people.

When are we obligated to believe someone? To what extent are people authorities about their own experiences? What kind of harm might we enact when we doubt? Questions like these lie at the heart of many debates in social and feminist epistemology, and they’re the driving issue behind a key conceptual framework in these debates—gaslighting. But while the concept of gaslighting has provided fruitful insight, it's also proven somewhat difficult to adjudicate, and seems prone to over-application. In what follows, I argue that Katherine Hawley's theory of trust can provide a useful alternative lens for looking at contested testimony. To do this, I focus on a particularly complex—but increasingly popular—application of gaslighting: the physician/patient relationship, and the idea of ‘medical gaslighting’. I argue that, even though patients can experience harm when they are disbelieved, there are nevertheless good reasons for physicians not to trust patients about at least some of their own narratives.

We discuss arguments against the thesis that the world itself can be vague. The first section of the paper distinguishes dialectically effective from ineffective arguments against metaphysical vagueness. The second section constructs an argument against metaphysical vagueness that promises to be of the dialectically effective sort: an argument against objects with vague parts. Firstly, cases of vague parthood commit one to cases of vague identity. But we argue that Evans' famous argument against will not on its own enable one to complete the reductio in the present context. We provide a metaphysical premise that would complete the reductio, but note that it seems deniable. We conclude by drawing general morals from our case study.

Metaphysicians eager to engage with substantive, thoughtful, and provocative issues will be happy with John Heil’s From an Ontological Point of View. The book represents not only a sustained defence of a specific metaphysical theory, but also of a specific way of doing metaphysics. Put ontology first, Heil urges us, in order to remember that the original fascination of metaphysics wasn’t the question ‘what must the world be like in order to correspond neatly to our use of language?’, but rather the altogether more fundamental ‘what must the world be like?’.

Guy Kahane and Julian Savulescu respond to my paper “Valuing Disability, Causing Disability” by arguing that my assessment of objections to the mere-difference view of disability is unconvincing and fails to explain their conviction that it is impermissible to cause disability. In reply, I argue that their response misconstrues, somewhat radically, both what I say in my paper and the commitments of the mere-difference view more generally. It also fails to adequately appreciate the unique epistemic factors present in philosophical discussions of disability.

In this paper I develop a framework for understanding ontic vagueness. The project of the paper is two-fold. I first outline a definitional account of ontic vagueness – one that I think is an improvement on previous attempts because it remains neutral on other, independent metaphysical issues. I then develop one potential manifestation of that basic definitional structure. This is a more robust (and much less neutral) account which gives a fully classical explication of ontic vagueness via modal concepts. The overarching aim is to systematically investigate the puzzling question of what exactly it could be for the world itself to be vague.

Disability is primarily a social phenomenon -- a way of being a minority, a way of facing social oppression, but not a way of being inherently or intrinsically worse off. This is how disability is understood in the Disability Rights and Disability Pride movements; but there is a massive disconnect with the way disability is typically viewed within analytic philosophy. The idea that disability is not inherently bad or sub-optimal is one that many philosophers treat with open skepticism, and sometimes even with scorn. The goal of this book is to articulate and defend a version of the view of disability that is common in the Disability Rights movement. To be physically disabled is not to have a defective body, but simply to have a minority body.
