Surrogacy and adoption are both family-making measures subject to extensive domestic and international regulation. In this nationally representative survey study (N = 1552), we explore public attitudes to various forms of surrogacy and adoption in the United Kingdom, in response to an early proposal to allow “double donor” surrogacy as part of the ongoing legal reform project. We sought to both gauge public moral support for adoption and surrogacy generally, the effect that prospective parents’ fertility had on this support, and (...) the extent to which the public would find equivalencies between “double donor” surrogacy (DDS) and planned private adoption (PPA) to be morally significant. Our findings indicate that whilst there is broad baseline support for all forms of adoption and surrogacy, this support increases significantly when one or both prospective parents are infertile. These findings also suggest that the language in which a family-making arrangement is characterized has a greater influence on moral support for the arrangement than practical features such as the biological relationship (or absence thereof) between one/both parents and the child.

Why does the practice of the siesta vary across human cultures? One explanation is that it is a form of energy conservation in environments with high temperatures and/or agricultural labor. Disease palliation and prevention represents another area where the siesta might be beneficial. A preliminary study used the Human Relations Area Files (HRAF) to examine the characteristics associated with siesta occurrence. Siestas were not statistically associated with high temperatures or agricultural labor (p>.05). They were, however, statistically associated with the occurrence (...) of malaria (p<.05) and marginally associated with parasitic and chronic infectious disease. Preliminary results suggest that siestas could be adaptive in environments with chronic infectious disease. (shrink)

Epistemic circularity occurs when a subject forms the belief that a faculty F is reliable through the use of F. Although this is often thought to be vicious, externalist theories generally don't rule it out. For some philosophers, this is a reason to reject externalism. However, Michael Bergmann defends externalism by drawing on the tradition of common sense in two ways. First, he concedes that epistemically circular beliefs cannot answer a subject's doubts about her cognitive faculties. But, he argues, subjects (...) don't have such doubts, so epistemically circular beliefs are rarely called upon to play this role. Second, following Thomas Reid, Bergmann argues that we have noninferential, though epistemically circular, knowledge that our faculties are reliable. I argue, however, that Bergmann's view is undermined by doubts a subject should have and that there is no plausible explanation for how we can have noninferential knowledge that our faculties are reliable.

30th Nov. and 1st Dec. 2013 at Kyoto University. Organizer: Takeshi Sakon.

Work in quantum gravity suggests that spacetime is not fundamental. Rather, spacetime emerges from an underlying, non-spatiotemporal reality. After clarifying the type of emergence at issue, I argue that standard conceptions of emergence available in metaphysics won’t work for the emergence of spacetime. I go on to consider spacetime functionalism as a way to make sense of spacetime emergence. I argue that a functionalist approach to spacetime modelled on mental state functionalism is not a viable alternative to the standard conception (...) of emergence in metaphysics. I go on to consider an alternative: ‘partial’ functionalism, whereby certain aspects of spacetime are functionalised, rather than spacetime as a whole. (shrink)

Doubtless, the conscious brain integrates masses of information. But declaring that consciousness simply “emerges” when enough has accumulated, doesn't really explain how first person experience is implemented by neurons. Moreover, empirical observations challenge integrated information theory's (IIT) reliance on thalamo–cortical interactions as the information integrator. More likely, the cortex streams processed information to a still-enigmatic consciousness generator, one perhaps located in the brainstem.

It is widely agreed that the top three Model Penal Code culpability levels suffice for criminal liability, but the fourth is controversial. And it isn’t just the particular MPC wording; that negligence should be on the list at all is controversial. My question is: What makes negligence so different? What is it about negligence that gives rise to the view that it should not suffice for criminal liability? In addressing it, I draw attention to how we conduct the debate, and (...) how our framing of the issues is shaping it. My hope is to prompt thought and discussion on just what we want the element of mens rea to provide, and to draw attention to background assumptions that shape our views of what it should take for negligence to count as a species of mens rea.

Current debate in the metaphysics of time ordinarily assumes that we should be realists about time. Recently, however, a number of physicists and philosophers of physics have proposed that time will play no role in a completed theory of quantum gravity. This paper defends fictionalism about temporal thought, on the supposition that our world is timeless. We argue that, in the face of timeless physical theories, realism about temporal thought is unsustainable: some kind of anti-realism must be adopted. We go (...) on to provide an argument against eliminativism about temporal thought. While it doesn't follow from this argument that fictionalism about temporal thought is true, we suggest that this nonetheless shows that fictionalism should be regarded as the preferred view.

The Triviality Argument against presentism maintains that we should reject presentism because there is no way to define the view that is not either trivially true or obviously false. We suggest that this style of argument over-emphasises purely linguistic means of representing a philosophical thesis. We argue that there is no reason to suppose that all philosophical theses must be linguistically representable, and thus that the failure to linguistically represent presentism is no big deal. It certainly shouldn’t lead us to (...) reject the view. We offer a more general moral for philosophy, and that is to look beyond purely linguistic methods of representing philosophical views and embrace a wider range of representational media. (shrink)

La réception du livre de Bergson chez les biologistes a été lente, partielle, voire irritée. Cette grande œuvre est ignorée des historiens de la biologie. Bergson n’a pas voulu faire une philosophie de la biologie, mais comprendre et exprimer de façon métaphorique le sens philosophique de l’évolution des espèces, le transformisme biologique. L’exigence de rigueur philosophique et la réflexion métaphysique de Bergson au sujet de la vie n’ont pas eu l’écho qu’il attendait, malgré le succès de l’œuvre. La réception théologique (...) a, elle aussi, été négative, et l’article examine les clauses de la mise à l’Index des trois premiers ouvrages de Bergson . La congrégation de l’Index a jugé dangereuse la philosophie bergsonienne au nom de préjugés néo-thomistes qui ne sont pas plus valables que les préjugés scientistes des biologistes.The Reception of Creative Evolution by the Biologists was slow, partial and sometimes angry. This important work is now ignored by the historians of Biology. Bergson won’t make a philosophy of Biology, but he does understand and express metaphorically the philosophical sense about the Evolution of Species and biological Transformism. The theological Reception was negative too. This feature studies the clauses of the sentence from Index which condemns Bergson’s three first works . The Congregation of Index makes a negative judgment about the bergsonian philosophy – on account of prejudice neothomistical which is not valid more than the scientist prejudice of the Biologists.

It is plausible that the models of our scientific theories correspond to possibilities. But exactly which models of which scientific theories stand in this correspondence? The answers to this question hinted at so far in the literature are too restrictive: they don't support the idea that the models of many of our best scientific theories correspond to physical possibilities. The paper thus provides a novel proposal for guiding belief about physical possibilities based on physics. The proposal draws on the notion (...) of an effective theory: a theory that applies very well to a particular, restricted domain. We argue that it is the models of effective theories that we should believe correspond, at least in part, to physical possibilities. It is thus effective theories that should guide modal reasoning in science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:25 MORALITY AS A BACK-UP SYSTEM: HUME'S VIEW? The sense of duty is a useful device for helping men to do what a really good man would do without a sense of duty..... Nowell-Smith A certain picture of morality — arguably a Humean one — has come to have a prominent place in contemporary philosophy. On this picture, morality, as Richard Brandt asserts, is "a back-up system, which operates (...) when spontaneous personal caring fails 2 to motivate us to do as we ought." Morality — at least in the form of moral principles, whose force is felt through one's sense of duty — is, on this view, ideally superfluous. As a guide for one's own conduct it is needed only insofar as the agent's affective network is deficient. If one only spontaneously desired a, cared about b, cared for c, felt aversion towards d as, ideally, one should, moral principles and a sense of duty would be of no use. There are good reasons for supposing that this is Hume's view. After all, his characterization of acting from duty is more than a little disparaging: When any virtuous motive or principle is common in human nature, a person, who feels his heart devoid of that motive, may hate himself upon that account, and may perform the action without the motive, from a certain sense of duty, in order to acquire by practice, that virtuous principle, or at least, to disguise to himself,,as much as possible, his want of it. I will argue, however, that there is tension in Hume's ethics between two lines of thought. According to the first line of thought, and the one 26 usually associated with Hume, good conduct is conduct which is spontaneously prompted by virtuous desires. Unless our desires either are not what they should be or are motivationally weak, there is no need for mediation or tempering by a sense of duty or moral principles. According to the second line, the very good desires of a very good person may nonetheless need to be filtered, tempered, redirected or checked. This line is most evident in "Of the Origin of the Natural Virtues and Vices." Before arguing that these strains of thought are in tension in Hume's ethics, I need to clarify what is at issue and to develop the two competing pictures of moral motivation. First the issue. The issue is not 'Who is better: someone with a sense of duty but corrupt desires or someone with no sense of duty but ideal desires?' Nor is the issue one of the moral worth of actions ('Can an action have moral worth if it is not performed out of duty?') The issue, rather, is how to characterize morally good (or right) conduct. What role, if any, does a sense of duty or a Butlerian principle of reflection, i.e., an overarching, guiding conception of what is right or good which is 'juridically' supreme within the self, play in good conduct? Is morally good conduct ideally a matter of acting as one should from the proper desires? Or should the desires be governed and guided by moral principles? Consider two models of moral conduct. Model I: Morality as a Back-Up System On this picture, wrongness in conduct is traceable to an affective deficiency. The claim underlying this picture seems to be as follows: One 27 acts wrongly because one's passions are not quite what they should be. One person cheats in her business dealings because she cares too little about the welfare of others (and too much about her own); another is harsh and abrupt to a student because he cares too little about his students' concerns and is jealous and possessive when it comes to 'his time.' In each case the problem can be traced to an affective deficiency. Hume appears to be supporting this view when he asserts, "it may be establish'd as an undoubted maxim, that no act can be virtuous, or morally good, unless there be in human nature some motive to produce it, distinct from a sense of its morality' (T 479). A few pages later he writes, "[E]very immorality... (shrink)

Rousseaus Verhältnis zu den Institutionen ist zumindest ambivalent, eher paradox: Einerseits gilt er als ein dezidierter Kritiker nicht nur der Institutionen seiner eigenen Zeit, sondern von Institutionalität überhaupt. Andererseits lässt sich kaum leugnen, dass Institutionen eine wichtige Rolle in seinem Denken spielen. Man mag darin eine gewisse Zwangsläufigkeit erkennen: Sofern Rousseau nicht nur kritisieren, sondern aktiv gestalten will, sofern er nicht nur punktuell intervenieren, sondern seinen reformerischen Vorschlägen Beständigkeit verleihen möchte, bleibt er auf Institutionen und Institutionalität angewiesen. Rousseau ist in (...) diesem Sinne kein Utopist: Auch wenn seine Schriften z.T. utopische Züge aufweisen, wenn sich in ihnen die Tendenz zum Ausbruch aus dem von der Gesellschaft gesteckten Rahmen manifestiert, kehren sie doch letztlich immer wieder zu den Institutionen zurück. Dass dies keine Kapitulation vor der Macht des Faktischen bedeutet, sondern ganz im Gegenteil den Realismus eines aufgeklärten Denkens ausmacht, das sich - obgleich eminent kritisch- stets aufs Neue vor institutionelle Herausforderungen stellt, belegen die in diesem Band versammelten Beiträge.

In this essay I rethink a view that I developed in my Kantian Ethics Almost Without Apology , concerning how ethical theory should handle the phenomena that are standardly classified as supererogatory acts. The view I elaborated rejects the standard contemporary picture, according to which ethics needs to draw a line separating duty from what is "beyond duty"--the supererogatory. On the Kantian picture, beneficent acts are not beyond duty, for we are required to help others, but we are not required (...) to help whenever possible, and so it is not the case that each individual beneficent act is required by duty. Helping is required; helping here and now is not. After contrasting this view with the standard picture and explaining that much of what contemporary philosophers wanted to capture with the notion of the supererogatory can be captured with the Kantian notion of imperfect duties together with attention to the agent's character, I raise some problems for my view and try to address them. First, what about heroic actions that are not in character? Don't we need the notion of supererogatory acts to recognize their greatness? Second, isn't virtue doing all the conceptual work? Is there even any need to appeal to the notion of imperfect duties? Third, although I claimed in my book that it is an advantage of the Kantian view that moral excellence comes in many varieties, arguably it is too pluralistic. In dem Beitrag überdenke ich eine Auffassung, die ich in meinem Buch Kantian Ethics Almost Without Apology entwickelt habe. Sie betrifft die Frage, wie ethische Theorien das Phänomen behandeln sollen, das üblicherweise als "Supererogation" bezeichnet wird. Die von mir ausgearbeitete Auffassung verwirft das heute gängige Bild, nach dem Ethik abgrenzen muß zwischen dem, was Pflicht ist, und dem, was "jenseits der Pflicht" steht -- dem Supererogatorischen. Nach Kants Vorstellung sind wohltätige Handlungen nicht jenseits der Pflicht, da wir verpflichtet sind, anderen zu helfen. Wir müssen jedoch nicht in jeder möglichen Situation helfen, und daher ist es nicht der Fall, daß jede einzelne wohltätige Handlung Pflicht ist. Hilfe zu leisten , ist geboten; Hilfe hier und jetzt zu leisten, nicht. In einer Gegenüberstellung dieser Auffassung mit der gängigen Vorstellung zeige ich, daß vieles von dem, was moderne Philosophen mit dem Begriff des Supererogatorischen erklären wollen, auch mit Kants Begriff der unvollkommenen Pflichten, verbunden mit einem Blick auf den Charakter des Handelnden, erklärt werden kann. Danach werfe ich einige Probleme auf, die sich meiner Auffassung stellen, und versuche, Antworten zu geben. Erstens: Wie steht es mit heldenhaften Handlungen, die nicht dem Charakter des Handelnden entsprechen? Brauchen wir nicht den Begriff des supererogatorischen Handelns, um ihre Größe zu erkennen? Zweitens: Genügt nicht der Begriff der Tugend? Besteht irgendeine Notwendigkeit, auf den Begriff der unvollkommenen Pflicht zurückzugreifen? Drittens: Obwohl ich in meinem Buch behaupte, es sei ein Vorteil der Kantischen Sicht, daß moralische Vortrefflichkeit viele Gesichter hat, ist Kants Auffassung doch vielleicht zu pluralistisch.

Context: Public universities in South Africa are currently facing the challenge of decolonising knowledge. This change requires a review of curriculums, as well as teaching and learning with the goal of embracing the epistemology of the learners, addressing issues such as social justice and transformation. Problem: Human communication is subject to several perceptual errors in both listening and seeing, which challenges the success of the communication in the education system. The ability of the teacher and the learners to effectively communicate (...) with one another is a factor for the success of each reaching their goals. The teacher imparts her knowledge in the classroom, but according to von Foerster, “[i]t is the listener, not the speaker, who determines the meaning of an utterance,” for the listener contextualises this information based on her own past lived experience. Thus, the student’s epistemology and her expression of her understanding is integral in the classroom context and should be actively included into the education system. Method: I present a cybernetic approach to the teacher-learner system, challenging traditional ideas about the role of each actor within the system, with special attention given to Pask’s conversation theory. Results: Early empirical findings suggest that a conversational contextual approach results in higher student involvement and better memory retention among the learners. Conversational approaches that are epistemologically inclusive diffuse social problems where the student groups require their individual worldviews to be reflected within the curriculum. This reduces the friction of competing epistemologies within the education system, moving toward a co-created contextually-driven knowledge system. Implications: Many educators would like deeper engagement from their learners but have not found a way to successfully engage the student group. A cybernetic approach is one method that can be adopted to remedy this. This is particularly useful in contexts where there is cultural diversity and impending social change. Constructivist content: I address von Glasersfeld’s points on human cognition, linking it to Austin’s speech acts. (shrink)

La notion de génie revêt une importance cruciale dans la pensée de Denis Diderot. En promouvant l'idée nouvelle d'homme de génie, le philosophe encyclopédiste contribua à transformer l'histoire culturelle de l'Europe. Dans son oeuvre, le génie se montre toujours en mouvement : il oscille entre la chaleur de l'enthousiasme et la froideur de l'esprit observateur ; il reflète les lois de la nature tout en les dépassant ; il perturbe toute certitude morale et apparaît, enfin, comme un moteur aussi ambivalent (...) qu'efficace du progrès. Les études rassemblées dans ce volume retracent l'hétérogénéité protéiforme du génie diderotien en mettant en valeur ses enjeux philosophiques, esthétiques, politiques et sociaux."--Page 4 of cover.

In this paper we confront a challenge to truthmaker theory that is analogous to the objections raised by deflationists against substantive theories of truth. Several critics of truthmaker theory espouse a ‘deflationary’ attitude about truthmaking, though it has not been clearly presented as such. Our goal is to articulate and then object to the underlying rationale behind deflationary truthmaking. We begin by developing the analogy between deflationary truth and deflationary truthmaking, and then show how the latter can be found in (...) the work of Dodd, Hornsby, Schnieder, Williamson, and others. These philosophers believe that the ambitions of truthmaker theory are easily satisfied, without recourse to ambitious ontological investigation—hence the analogy with deflationary truth. We argue that the deflationists’ agenda fails: there is no coherent deflationary theory of truthmaking. Truthmaking, once deflated, fails to address the questions at the heart of truthmaking investigation. Truthmaking cannot be had on the cheap. (shrink)

Although the method of Belgian budgeting and controlling has considerably improved during recent years, there still remain a lot of shortcommings such as: frequently late introduction into Parliament of the budget, inadequate information about expenditure, rarely application of zero base budgeting aften combined with techniques which embellish the budget. Debudgeting is the most important camouflage technique. Debudgeting appears in different manners and influences not only the height but also the evolution of the budget deficit. An improvement of the budgeting technique (...) in Belgium doesn't ask fundamental changes of actual law. Just a switch in applicating the law according to the original spirit and interpretation of actual legislation, would be satisfactory to obtain an efficient and effective budget-policy. (shrink)

Pierre le Pesant Boisguilbert was considered by Marx as one of the founders of classical political economy. His writings contain a large number of concepts and ideas that reappear in the writings of Quesnay, Cantillon and Adam Smith. George Berkeley - a major figure in the history of philosophical idealism - was the author of 'The Querist', a treatise on the nature of Irish under-development and cures for Irish poverty. Baron de Montesquieu - one of the great 18th century (...) polymaths - is author of the masterpiece 'The Spirit of the Laws' (1748) which, while ostensibly a treatise on law, is actually a study of political organization, types of government, national character and the determining ethos of different societies. It enjoyed enormous success in the 18th century and was almost certainly read and studied by Adam Smith. Ferdinando Galiani was a leading critic of physiocracy and a major 18th century proponent of the subjective theory of value. In 1751 he published 'Della Moneta' which contains some notable chapters on monetary theory, and some brilliant pages on the utility theory of value. James Anderson was a Scottish farmer and a prolific author of tracts on the agricultural development of Scotland and the outstanding policy issues of the last quarter of the 18th century. Dugald Stewart was author of 'Account of the Life and Writings of Adam Smith LLD' (1793) which is one of the earliest, extended commentaries on the works of Adam Smith by one who knew him well.

Justifications and excuses are defenses that exculpate. They are therefore much more like each other than like such defenses as diplomatic immunity, which does not exculpate. But they exculpate in different ways, and it has proven difficult to agree on just what that difference consists in. In this paper I take a step back from justification and excuse as concepts in criminal law, and look at the concepts as they arise in everyday life. To keep the task manageable, I focus (...) primarily on excuses and excusing activities, distinguishing them from justifications as well as from other close relatives, in particular, forgiving and pardoning. I draw upon J.L. Austin’s classic A Plea for Excuses, but expand on his account, suggesting that we offer excuses for reasons besides those he mentions. My hope is that my examination of excuses and excusing activities will help us rethink our views on just how justifications and excuses differ, views which often are worked out without much attention to how these concepts function in everyday life and to the connection between offers of excuses and justifications and the rules of civility.

We use a new model of metarepresentational development to predict a cognitive deficit which could explain a crucial component of the social impairment in childhood autism. One of the manifestations of a basic metarepresentational capacity is a ‘ theory of mind ’. We have reason to believe that autistic children lack such a ‘ theory ’. If this were so, then they would be unable to impute beliefs to others and to predict their behaviour. This hypothesis was tested using Wimmer (...) and Perner’s puppet play paradigm. Normal children and those with Down’s syndrome were used as controls for a group of autistic children. Even though the mental age of the autistic children was higher than that of the controls, they alone failed to impute beliefs to others. Thus the dysfunction we have postulated and demonstrated is independent of mental retardation and specific to autism. (shrink)

Standard approaches to counterfactuals in the philosophy of explanation are geared toward causal explanation. We show how to extend the counterfactual theory of explanation to non-causal cases, involving extra-mathematical explanation: the explanation of physical facts by mathematical facts. Using a structural equation framework, we model impossible perturbations to mathematics and the resulting differences made to physical explananda in two important cases of extra-mathematical explanation. We address some objections to our approach.

Mathematics appears to play a genuine explanatory role in science. But how do mathematical explanations work? Recently, a counterfactual approach to mathematical explanation has been suggested. I argue that such a view fails to differentiate the explanatory uses of mathematics within science from the non-explanatory uses. I go on to offer a solution to this problem by combining elements of the counterfactual theory of explanation with elements of a unification theory of explanation. The result is a theory according to which (...) a counterfactual is explanatory when it is an instance of a generalized counterfactual scheme. (shrink)

Time is woven into the fabric of our lives. Everything we do, we do in and across time. It is not just that our lives are stretched out in time, from the moment of birth to the moment of our death. It is that our lives are stories. We make sense of ourselves, today, by understanding who we were yesterday, and the day before, and the day before that; by understanding what we did and why we did it. Our memories (...) shape our present selves, since we are the product of who we were, and who we remember being. Yet who we are lasts for but a moment. It is who we will be that demands attention. We are forever projecting ourselves into the future. We painstakingly plan for the needs of our future selves, all the while knowing that while what we do will make those future selves who they are, still, our future selves are elusive. So it is not simply that we happen to live our lives in time, the way, say, one might happen to live in Australia, or Singapore. It is hard to fathom how things could be otherwise. What would it be to live a life without time? Yet time itself is intangible. Though we are keenly aware of what has been ‒ of pain and loss, regret and pride ‒ and of what might be ‒ of anticipation, and dread, and longing ‒ time itself seems unaffected by anything we do. Though we can anticipate a future birthday cake, time itself cannot be tasted. Though we can dread a future dentist’s appointment, time itself cannot be touched. Though we remember the crunching of leaves this past autumn, time itself cannot be heard. How can it be that something so central to each of us, to who we are, and what we care about, can be so spectral? What, in the end, is time? Is time real, like a substance in which each of us, like insects in amber, finds ourselves trapped? Is time a dimension through which we can move? Is time not a thing at all, but some connection between events? If time is real, what is it like? Does it flow like a river, taking each of us prisoner in its current, washing us ever closer to the end of our lives? Is time like a cresting wave, coming ever closer to each of us from the future, engulfing us, and then receding into the past? Or is time static? Like a one-way road that each of us might wander, with no chance to turn back? Or perhaps time is like none of these things. Perhaps time is more like space; something we can navigate freely, so that we can visit different times just like we visit different places. Perhaps we can we travel in time the way we can travel in space. These questions, and many more, are the focus of this book. Now, you might wonder what philosophers are doing writing a book about time. Surely that’s a job for physicists! It is true: a great deal of what we know about time stems from our understanding of physics. However, even in physics we find that there are questions about time that go unanswered. Moreover, increasingly, physicists are turning to philosophers for help in understanding the role that time plays in current physical theories. Our goal is to get the reader up to speed on some of the central issues that influence our understanding of time so that they too may play a role in this ongoing discussion between science and philosophy. We hope that in doing so it will become clear what philosophy can bring to the study of time. There is a natural narrative in philosophy regarding the study of time, and we have chosen to organise this book according to that narrative. However, the book may also be approached in a ‘choose-your-own adventure’ spirit. While later chapters build on material introduced in earlier chapters, you can skip around, reading the book in any order you choose. For the instructor, this means that she can design her course around this book in any number of ways, depending on the particular topic she wishes to focus on. (shrink)

Is time necessary for causation? We argue that, given a counterfactual theory of causation, it is not. We defend this claim by considering cases of counterfactual dependence in quantum mechanics. These cases involve laws of nature that govern entanglement. These laws make possible the evaluation of causal counterfactuals between space-like separated entangled particles. There is, for the proponent of a counterfactual theory of causation, a possible world in which causation but not time exists that can be reached by ‘stripping out’ (...) time from the actual world, leaving quantum mechanical laws intact.

During the past decade ethical theory has been in a lively state of development, and three basic approaches to ethics - Kantian ethics, consequentialism, and virtue ethics - have assumed positions of particular prominence.

This paper addresses the extent to which both Julian Barbour‘s Machian formulation of general relativity and his interpretation of canonical quantum gravity can be called timeless. We differentiate two types of timelessness in Barbour‘s (1994a, 1994b and 1999c). We argue that Barbour‘s metaphysical contention that ours is a timeless world is crucially lacking an account of the essential features of time—an account of what features our world would need to have if it were to count as being one in which (...) there is time. We attempt to provide such an account through considerations of both the representation of time in physical theory and in orthodox metaphysical analyses. We subsequently argue that Barbour‘s claim of timelessness is dubious with respect to his Machian formulation of general relativity but warranted with respect to his interpretation of canonical quantum gravity. We conclude by discussing the extent to which we should be concerned by the implications of Barbour‘s view. (shrink)

According to dialetheism, there are some true contradictions. According to the A-theory, the passage of time is a mind-independent feature of reality. On some A-theories, the passage of time involves the movement of the present. I show that by appealing to dialetheism one can explain why the present moves. I then argue that A-theorists should adopt this explanation. To do this, I defend two claims. First, that the dialetheic explanation is an improvement on the only other explanation available for why (...) the present moves and, second, that adopting the explanation is better than leaving the motion of the present unexplained. Assuming that A- theorists should adopt the best available version of their view, it follows that they should adopt a dialetheic explanation of why time passes. (shrink)

In this paper, we explore locative grounding harmony, according to which the location of the grounds mirrors the location of the grounded. We proceed in three stages. First, we clarify the notion of locative harmony and describe different locative harmony principles. Second, we offer two arguments for the claim that grounding between physically located entities obeys principles of locative harmony. Third, we consider and respond to a range of cases that seem to show that grounding relations between physically located entities (...) do not obey such principles. We conclude that grounding between such entities obeys locative harmony. (shrink)

Why do children with autism have such trouble developing normal social understanding of other people's feelings? This new edition updates the field by linking autism research to the newest methods for studying the brain.

Presentism faces a serious challenge from truthmaker theory. Standard solutions to the truthmaker objection against presentism proceed in one of two ways. Easy road presentists invoke new entities to satisfy the requirements of truthmaker theory. Hard road presentists, by contrast, flatly refuse to give in to truthmaker demands. Recently, a third way has been proposed. This response seeks to address the truthmaking problem by tensing our truthmaker principles. These views, though intuitive, are under-developed. In this paper, I get serious about (...) a fundamentally tensed approach to truthmaking by sketching out the underlying ontological picture needed to make sense of tensed truthmaker theory. (shrink)

The existence and fundamentality of spacetime has been questioned in quantum gravity where spacetime is frequently described as emerging from a more fundamental non-spatiotemporal ontology. This is supposed to lead to various philosophical issues such as the problem of empirical coherence. Yet those issues assume beforehand that we actually understand and agree on the nature of spacetime. Reviewing popular conceptions of spacetime, we find that there is substantial disagreement on this matter, and little hope of resolving it. However, we argue (...) that this should not trouble us as these issues, which seem to suggest the need for an account of spacetime in quantum gravity, can be addressed without one. (shrink)

Priority monism (hereafter, ‘monism’) is the view that there exists one fundamental entity—the world—and that all other objects that exist (a set of objects typically taken to include tables, chairs, and the whole menagerie of everyday items) are merely derivative. Jonathan Schaffer has defended monism in its current guise, across a range of papers. Each paper looks to add something to the monistic picture of the world. In this paper we argue that monism—as Schaffer describes it—is false. To do so (...) we develop an ‘island universe’ argument against Schaffer's monistic theory. (shrink)

Enhanced indispensability arguments seek to establish realism about mathematics based on the explanatory role that mathematics plays in science. Idealizations pose a problem for such arguments. Idealizations, in a similar way to mathematics, boost the explanatory credentials of our best scientific theories. And yet, idealizations are not the sorts of things that are supposed to attract a realist attitude. I argue that the explanatory symmetry between idealizations and mathematics can potentially be broken as follows: although idealizations contribute to the explanatory (...) power of our best theories, they do not carry the explanatory load. It is at least open however that mathematics is load-carrying. To give this idea substance, I offer an analysis of what it is to carry the explanatory load in terms of difference-making and counterfactuals. (shrink)
