Abstract Temporal Externalism is the view that future events can contribute to determining the present content of our thoughts and utterances. Two objections to Temporal Externalism are discussed and rejected. The first is that Temporal Externalism has implausible consequences for the epistemology of biology and other taxonomic sciences (Brown, 2000). The second is that it is committed to implausible claims about dispositions.

Jessica Wilson has recently offered a more sophisticated version of the self-defeat objection to Cartesian scepicism. She argues that the assertion of Cartesian scepticism results in an unstable vicious regress. The way out of the regress is to not engage with the Cartesian sceptic at all, to stop the regress before it starts, at the warranted assertion that the external world exists. We offer three reasons why this objection fails: first, the sceptic need not accept Wilson’s characterization of the sceptical (...) thesis and thus need not start her regress; second, even if she did commit to the regress, it would not undermine scepticism in the way Wilson envisages; and third, the appeal to mental state scepticism which is necessary to generate the second and subsequent steps in the regress is not justified.

Tom Stoneham offers a clear and detailed study of Berkeley's metaphysics and epistemology, as presented in his classic work Three Dialogues between Hylas and Philonous, originally published in 1713 and still widely studied. Stoneham shows that Berkeley is an important and systematic philosopher whose work is still of relevance to philosophers today.

There are many questions we can ask about time, but perhaps the most fundamental is whether there are metaphysically interesting differences between past, present and future events. An eternalist believes in a block universe: past, present and future events are all on an equal footing. A gradualist believes in a growing block: he agress with the eternalist about the past and the present but not about the future. A presentist believes that what is present has a special status. My first (...) claim is that the familiar ways of articulating these views result in there being no substantive disagreement at all between the three parties. I then show that if we accept the controversial truthmaking principle, we can articulate a substantive disagreenment. Finally, I apply this way of formulating the debate to related questions such as the open future and determinism, showing that these do not always line up in quite the way one would expect. (shrink)

An argument is presented which shows that coherence theories of justification are committed to a conception of epistemic support which conflicts with an axiom of probability theory.

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. (shrink)

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 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. (shrink)

It is argued that a second-order belief to the effect that I now have some particular propositional attitude is always true (Incorrigibility). This is not because we possess an infallible cognitive faculty of introspection, but because that x believes that he himself now has attitude A to proposition P entails that x has A to P. Incorrigibility applies only to second-order beliefs and not to mere linguistic avowals of attitudes. This view combines a necessary asymmetry between 1st and 3rd person (...) ascriptions with Objectivism about the propositional attitudes. The epistemic justification of second-order beliefs is shown to be a further question. (shrink)

Paul Boghossian has argued that Externalism is incompatible with privileged self-knowledge because (i) the Externalist can cite no property to be the reference of an empty natural kind concept such as the ether; (ii) without reference there is no content; hence (iii) either we do know on the basis of introspection alone whether an apparent natural kind thought has content or not, in which case we can infer from self-knowledge and a priori knowledge of Externalism alone to the existence in (...) our environment of water, gold etc.; (iv) or we do not know, without empirical investigation, whether an apparent natural kind thought has content. An Externalist not wanting to accept either (iii) or (iv) can deny (i). All empty natural kind concepts refer to the necessarily uninstantiated property of being identical to nothing. Since they have different senses and self-knowledge is only held to extend to the existence and identity of sense, this is compatible with privileged self-knowledge, and Externalism is still true of the concepts.

I aim to draw the reader's attention to an easily overlooked account of perception, namely that there are no perceptual experiences, that to perceive something is to stand in an external, purely non-Leibnizian relation to it. I introduce the Purely Relational account of perception by discussing a case of it being overlooked in the writings of G.E. Moore, though we also find the same move in J. Cook Wilson, so it has nothing to do with an affection for sense-data. I (...) then discuss the relation between the PR account and recent disjunctive accounts of perceptual experience, and note that the PR account has some claim to be the only one that truly respects the directness of perception. The paper does not aspire to persuade the reader of the correctness of the neglected PR account, merely that it should be treated as a serious candidate in philosophical debates about perception.

Berkeley thinks that we only see the size, shape, location, and orientation of objects in virtue of the correlation between sight and touch. Shadows have all of these spatial properties and yet are intangible. In Seeing Dark Things (2008), Roy Sorensen argues that shadows provide a counterexample to Berkeley's theory of vision and, consequently, to his idealism. This paper shows that Berkeley can accept both that shadows are intangible and that they have spatial properties.

In this paper, we give a precise characterization of the principle of recombination and argue that it need not be subject to any restrictions.

Equivocation is often described as a fallacy. In this short note I argue that it is not a logical concept but an epistemic one. The argument of one who equivocates is not logically flawed, but it is unpersuasive in a very distinctive way.

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. (shrink)

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.

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. (shrink)

We argue that Armstrong's Combinatorialism allows for the possibility of nothing by giving a Combinatorial account of the empty world and show that such an account is consistent with the ontological and conceptual aims of the theory. We then suggest that the Combinatorialist should allow for this possibility given some methodological considerations. Consequently, rather than being 'spoils for the victor', as Armstrong maintains, deciding whether there might have been nothing helps to determine which metaphysics of modality is to be preferred.

Ross Cameron charges the subtraction argument for metaphysical nihilism with equivocation: each premise is plausible only under different interpretations of 'concrete'. This charge is ungrounded; the argument is both valid and supported by basic modal intuitions.

Some philosophers have thought that life could only be meaningful if there is no God. For Sartre and Nagel, for example, a God of the traditional classical theistic sort would constrain our powers of self-creative autonomy in ways that would severely detract from the meaning of our lives, possibly even evacuate our lives of all meaning. Some philosophers, by contrast, have thought that life could only be meaningful if there is a God. God and the Meanings of Life is interested (...) in exploring the truth in both these schools of thought, seeking to discover what God could and couldn't do to make life meaningful (as well as what he would and wouldn't do). Mawson espouses a version of the 'amalgam' or 'pluralism' thesis about the issue of life's meaning – in essence, that there are a number of different legitimate meanings of 'meaning' (and indeed 'life') in the question of life's meaning. According to Mawson, God, were he to exist, would help make life meaningful in some of these senses and hinder in some others. He argues that whilst there could be meaning in a Godless universe, there could be other sorts of meaning in a Godly one and that these would be deeper. (shrink)

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. (shrink)

Jonathan Schaffer has recently argued that there can be objects having only mass. We show that his argument is either invalid or question begging.

T. A. Cavanaugh's Hippocrates' Oath and Asclepius' Snake: The Birth of the Medical Profession articulates the Oath as establishing the medical profession's unique internal medical ethic - in its most basic and least controvertible form, this ethic mandates that physicians help and not harm the sick. Relying on Greek myth, drama, and medical experience (e.g., homeopathy), the book shows how this medical ethic arose from reflection on the most vexing medical-ethical problem -- injury caused by a physician -- and argues (...) that deliberate iatrogenic harm, especially the harm of a doctor choosing to kill (physician assisted suicide, euthanasia, abortion, and involvement in capital punishment), amounts to an abandonment of medicine as an exclusively therapeutic profession. The book argues that medicine as a profession necessarily involves stating before others what one stands for: the good one seeks and the bad one seeks to avoid on behalf of the sick, and rejects the view that medicine is purely a technique lacking its own unique internal ethic. It concludes noting that medical promising (as found in the White Coat Ceremony through which U. S. medical students matriculate) implicates medical autonomy which in turn merits respect, including honoring professional conscientious objections. (shrink)
