Embodiment is a fact of human existence which philosophers should not ignore. They may differ to a great extent in what they have to say about our bodies, but they have to take into account that for each of us our body has a special status, it is not merely one amongst the physical objects, but a physical object to which we have a unique relation. While Descartes approached the issue of embodiment through consideration of sensation and imagination, it is more directly reached by consideration of action and agency: whenever we act upon the world, we act by moving our bodies. So if we can understand what an immaterialist such as Berkeley thinks about agency, we will have gone a fair way to understanding what he thinks about embodiment. §1 discusses a recent flurry of articles on the subject of Berkeley’s account of action. I choose to present Berkeley as a causal-volitional theorist (realist) not because I think it is the uniquely correct interpretation of the texts, but because I find it more philosophically interesting as a version of immaterialism. In particular, it raises the possibility of a substantive account of human embodiment which is completely unavailable to the occasionalist. §2 articulates an apparent philosophical problem for Berkeley qua causal-volitional theorist and show that Locke was aware of a related problem and had a solution of which Berkeley would have known. §3 distinguishes two interpretations of Berkeley’s famous denial of blind agency – as the assertion of a weak representational condition or a strong epistemic one – and provide evidence that there was a well-established debate about blind powers in the seventeenth century which took the metaphor of blindness as indicating an epistemic rather than merely representational failing. What remains to do in §4 is to consider whether Berkeley, with his own peculiar commitments, could in fact accept this account of agency.

Locke and Leibniz on Substance gathers together papers by an international group of academic experts, examining the metaphysical concept of substance in the writings of these two towering philosophers of the early modern period. Each of these newly-commissioned essays considers important interpretative issues concerning the role that the notion of substance plays in the work of Locke and Leibniz, and its intersection with other key issues, such as personal identity. Contributors also consider the relationship between the two philosophers and contemporaries such as Descartes and Hume

In well-documented cases, it is plausibly unethical to ask trauma sufferers for details relating to their trauma. We propose that the reasons are twofold: First, the details requested are not required by those asking for them; second, the request comes with potential for significant harm for the victim arising from the exchange. Requests meeting these conditions are widespread, including in predominant forms of psychotherapy, so accepting these conditions has surprising and challenging consequences for a wide range of interactions with the victims of trauma, including well-meaning ones. Given these surprising and challenging consequences, we explore what, if anything, could offset the two conditions, focusing primarily on therapeutic interactions, which are sometimes thought to have a distinctive or sui generis character. We conclude that none of the options we consider wholly off-set the two conditions, and that they are only partly off-set by insufficient research into alternatives. We outline implications for the status of treatments which require the recollection of trauma as the default kind of intervention, and for interactions with victims of trauma more broadly.

We argue that genuine modal realism can be extended, rather than modified, so as to allow for the possibility of nothing concrete, a possibility we term ‘metaphysical nihilism’. The issue should be important to the genuine modal realist because, not only is metaphysical nihilism itself intuitively plausible, but also it is supported by an argument with pre-theoretically credible premises, namely, the subtraction argument. Given the soundness of the subtraction argument, we show that there are two ways that the genuine modal realist can accommodate metaphysical nihilism: (i) by allowing for worlds containing only spatiotemporal points and (ii) by allowing for a world containing nothing but the null individual. On methodological grounds, we argue that the genuine modal realist should reject the former way but embrace the latter way.

Suppose nothing exists. Then it is true that nothing exists. What makes that true? Nothing! So it seems that if nothing existed, then the principle that every truth is made true by something (the truthmaker principle) would be false. So if it is possible that nothing exists, a claim often called 'metaphysical nihilism', then the truthmaker principle is not necessary. This paper explores various ways to resolve this conflict without restricting metaphysical nihilism in such a way that it would become trivial and uninteresting.

This volume brings together a collection of new essays by leading scholars on the subject of causation in the early modern period, from Descartes to Lady Mary Shepherd. Aimed at researchers, graduate students and advanced undergraduates, the volume advances the understanding of early modern discussions of causation, and situates these discussions in the wider context of early modern philosophy and science. Specifically, the volume contains essays on key early modern thinkers, such as Descartes, Hobbes, Spinoza, Leibniz, Hume, Kant. It also contains essays that examine the important contributions to the causation debate of less widely discussed figures, including Louis la Forge, Thomas Brown and Lady Mary Shepherd.

Could an object have only mass and no other property? In giving an affirmative answer to this question, Jonathan Schaffer (2003, pp. 136-8) proposes what he calls ‘the subtraction argument’ for ‘the possibility of free mass’. In what follows, we aim to assess the cogency of this argument in comparison with an argument of the same general form which has also been termed a subtraction argument, namely, Thomas Baldwin’s (1996) subtraction argument for metaphysical nihilism, which is the claim that there might have been no concrete objects. The comparison will be instructive because Baldwin’s argument has been the subject of considerable recent debate (of particular relevance for current purposes are Paseau 2002, Authors 2005, and Paseau 2006), and the lesson of this debate seems to be that subtraction arguments, such as Baldwin’s and Schaffer’s, are faced with a dilemma: either they are invalid or they fail to be suasive. We outline how Baldwin’s argument can be reformulated so as to avoid both horns of this dilemma, and we then argue that Schaffer’s argument cannot so avoid the dilemma.
