I argue that David Lewis’s philosophically dominant conception of time travel cannot straightforwardly handle what we might call cases of relativistic time travel—that is, the sort of time travel which could only plausibly occur in a relativistic setting. I evaluate whether or not the Lewisian account can be successfully adapted such that it would able to analyse potential cases of relativistic time travel satisfactorily while still being employable in the analysis of those cases that make no mention of physics or (...) the structure of spacetime. This is primarily an analytical and explanatory exercise, rather than a polemical one. (shrink)

Mereological challenges have recently been raised against the endurantist. For instance, Barker and Dowe (2003) have argued that eternalist endurantism entails (1) persisting objects are both 3D and 4D, and that (2) the lives of persisting objects last longer than they actually do. They also argue that presentist endurantism also entails, albeit in a tensed way, that (3) the lives of persisting objects last longer than they actually do. While they’ve further argued (2005) that the objections raised by McDaniel (2003) (...) and Beebee and Rush (2003) fail, here I show that such objections are tenable without requiring further significant metaphysical commitments; I argue that such endurantist defences are tenable, contra to prior analyses. (shrink)

Endurantists have recently faced a mereological puzzle in various forms. Here I argue that, instead of presenting a genuine worry, the puzzle actually reveals a common misunderstanding about the endurantist ontology. Furthermore, through this discussion of the alleged problem and the misunderstanding which motivates it, I reveal metaphysical commitments the endurantist has that may not be widely recognized. For instance, she is committed to interesting and perhaps controversial views about shape and location. I highlight these commitments and what they mean (...) for the endurantist. (shrink)

We argue that mereological essentialism for events is independent of mereological essentialism for objects, and that the philosophical fallout of embracing mereological essentialism for events is minimal. We first outline what we should consider to be the parts of events, and then highlight why one would naturally be inclined to think that the object-question and the event-question are linked. Then, we argue that they are not. We also diagnose why this is the case and emphasize the upshot. In particular, we (...) argue that the way we evaluate modal claims which concern events differs from the way we evaluate modal claims which concern objects. Ultimately, then, to our title question we say: the answer does not matter as much as you might think. (shrink)

Nietzsche and "The birth of tragedy"" provides a clear account of the text and explores the philosophical, literary and historical influences bearing upon it. Each chapter examines part of the text, explaining the ideas presented and assessing relevant scholarly points of interpretation. The book will be an invaluable guide to readers in philosophy, literary studies and classical studies coming to "The birth of tragedy" for the first time.

Here I defend the compatibility of presentism and time travel against a few objections. Keller and Nelson argue that, if presentism is at all plausible, presentism and time travel are as compatible as eternalism and time travel. But Miller and Sider are not convinced. I reply that for their concerns to have merit, Miller and Sider must assume presentists are committed to positions they need not be; I explain why presentists are not so committed and, in the process, defend Keller (...) and Nelson’s position that there is no roadblock to presentist time travel that does not also apply to eternalist time travel.

I explicate and defend a non-standard theory of persistence, which I calltransdurantism. In short, transdurantism is the view is that objects persist by being temporally extended simples. Transdurantism is sometime misrepresented as a version of endurantism. Other times, transdurantism is misrepresented as a version of perdurantism. But I argue transdurantism must be disambiguated from perdurantism and endurantism—when endurantism, perdurantism, and transdurantism are properly construed, transdurantism stands apart from the other theories of persistence and we can better understand the distinct burdens (...) they each bear. I also argue that the transdurantist is capable of handling several key problems found in the persistence literature at least as well as her rivals, but she does face her own unique challenges. (shrink)

According to the presentist, only the present moment exists and, as time passes, what’s present changes. However some argue that, if only one moment exists, the presentist cannot explain the passage of time. While the presentist historically appeals to surrogates—proxies which exist in the present but play the role of non-existent past times—to evade this sort of worry, the appeal to surrogates has come under renewed attack from Lisa Leininger. But hope is not lost for the presentist. I argue that (...) presentists do have the resources available to address the underlying issue Leininger articulates. Moreover, there’s disagreement amongst presentists about which version of presentism is best. For instance, David Ingram has recently argued that thisness presentism is preferable to other versions of presentism because it’s able to handle certain problems other versions of presentism cannot. However, I argue that this assessment is premature. More specifically, I argue that Ingram’s response to an objection from Lisa Leininger fails to address the core issue she raises. Consequently, I argue that presentists shouldn’t embrace thisness presentism just yet. In this way, my aims here are to: sharpen Leininger’s objection, highlight tenable presentist replies to it, and advance the discussion about which version of presentism should be favoured. (shrink)

Endurantism is commonly characterized as a sweeping thesis, according to which enduring objects persist by sweeping or moving through time. I argue that the endurantist should resist this characterization as it makes her view incompatible with eternalism, the moving spotlight theory, and the growing block theory. Moreover, even the presentist endurantist should resist this characterization as it undermines the modal analogy. As a result, those who argue against endurantism should avoid characterizing endurantism in this way. Through this discussion we can (...) better understand the endurantist picture and appreciate why caution is needed when characterizing the nature of enduring objects. (shrink)

Nietzsche's philosophy - at once revolutionary, erudite and deep - reaches into all spheres of the arts. Well into a second century of influence, the profundity of his ideas and the complexity of his writings still determine Nietzsche's power to engage his readers. His first book, "The Birth of Tragedy", presents us with a lively inquiry into the existential meaning of Greek tragedy. We are confronted with the idea that the awful truth of our existence can be revealed through tragic (...) art, whereby our relationship to the world transfigures from pessimistic despair into sublime elation and affirmation. It is a landmark text in his oeuvre and remains an important book both for newcomers to Nietzsche and those wishing to enrich their appreciation of his mature writings. "Nietzsche and The Birth of Tragedy" provides a clear account of the text and explores the philosophical, literary and historical influences bearing upon it. Each chapter examines part of the text, explaining the ideas presented and assessing relevant scholarly points of interpretation.

The main theme of this thesis is time travel; time travel cases—both from relativistic physics and science fiction—provide or highlight deep problems for certain positions in contemporary debates about the metaphysical nature of time and of how material objects persist through time. This thesis explores the implications of these discussions; more specifically, I draw attention to some of the interesting things we can learn about presentism and endurantism from discussions of time travel cases that have been raised recently in the (...) literature. In the end, I argue in favour of what I consider a non-standard theory of persistence, which I call transdurantism, according to which persisting objects are temporally extended simples. (shrink)

In the Critique of the Power of Judgment, Immanuel Kant proposes a puzzling account of the experience of the beautiful: that aesthetic judgments are both subjective and speak with a universal voice. 1 These properties – the subjective and the universal – seem mutually exclusive but Kant maintains that they are compatible if we explain aesthetic judgment in terms of the mind’s a priori structure, as explicated in his earlier Critique of Pure Reason. Kant advances two major claims towards arguing (...) for the compatibility of the subjectivity and universality of the experience of beauty: that aesthetic judgments are ‘disinterested’, and that the universality of an aesthetic judgment derives from the transcendental idealist’s account of ordinary spatio-temporal experience – that is, our ordinary cognitive framework can explain the experience of beauty. If correct, these two claims support the thesis that, while the experience of beauty is wholly subjective, it nevertheless speaks with a universal voice . I will move to interpret Kant’s theory of the beautiful with reference to his earlier two Critiques in order to better understand the marriage of subjectivity and universality. In turn, this re- veals a deeper symmetry between the disinterestedness of the experience of beauty and the freedom of moral action, allowing Kant to maintain, as he indeed does, that “beauty is the symbol of morality.”.

In The Langoliers, passengers on an airline flight wake to find that they’ve mysteriously travelled a few minutes back in time… a few minutes behind everyone else. They find that the world still exists, after ‘the present’ has moved on, but only for a short duration before the Langoliers—the timekeepers of eternity—arrive to remove it permanently from existence. This story prompts two interesting questions: How should we understand the nature of time in The Langoliers? Could the nature of time in (...) our world be the same as in The Langoliers? And, are the characters in The Langoliers really time travellers? In answering these questions, we can gain a greater understanding of the world depicted in The Langoliers, as well as of our own world. (shrink)

I argue that, according to Just War Theory, those who work as administrative personnel in the private military industry can be permissibly harmed while at work by enemy combatants. That is, for better or worse, a Just War theorist should consider all those who work as administrative personnel in the private military industry either: (i) individuals who may be permissibly restrained with lethal force while at work, or (ii) individuals who may be harmed by permissible attacks against their workplace. In (...) doing so, I also provide some critical analysis of the relevant Just War concepts. (shrink)

In this paper, I first explain Slajov Žižek’s analysis of the grounds of Kant’s categorical imperative. I show how Žižek considered the grounds of the categorical imperative to be an example of irrationalism that ran counter to the spirit of the Enlightenment, of which Kant was, ironically, a major proponent. The irrationalism in Kant’s moral law makes him vulnerable to moral skepticism. I go on to counter this interpretation by drawing from Kant’s practical philosophy. I counter the moral skeptic by (...) arguing from moral phenomenology to the existence of a reason that is independent of empirical motivations and so objectively determining. Whatever is objectively determining logically supersedes that which is based on a particular context. The moral law is rooted in the ontology of an independent faculty of reason capable of issuing a universal law. The union of ontology and ethics means that the categorical imperative is not irrational. (shrink)

The present research was designed to test whether the subjective experience of more effort related to more reward valuation as measured by a neural response. This prediction was derived from the theory of cognitive dissonance and its effort justification paradigm. Young adult participants (n = 82) engaged in multiple trails of a low or high effort task that resulted in a loss or reward on each trial. Neural responses to the reward (loss) cue were measured using EEG, so that the (...) event-related potential known as the Reward Positivity (RewP) could be assessed. Results revealed no significant differences between low and high effort conditions on the RewP. However, within the high effort condition, a more subjective experience of effort was associated with a larger RewP. This research extends past research on the effort justification paradigm of cognitive dissonance theory by suggesting that effort justification is associated with an implicit measure of reward valuation. It therefore challenges recent perspectives on dissonance processes that posit that these evaluative changes should only occur on explicit but not implicit measures. (shrink)

In the research ethics literature, there is strong disagreement about the ethical acceptability of placebo-controlled trials, particularly when a tested therapy aims to alleviate a condition for which standard treatment exists. Recently, this disagreement has given rise to debate over the moral appropriateness of the principle of clinical equipoise for medical research. Underlying these debates are two fundamentally different visions of the moral obligations that investigators owe their subjects.Some commentators and ethics documents claim that physicians, whether acting as care givers (...) or researchers, have the same duty of beneficence towards their patients and subjects: namely, that they must provide optimal medical care. In discussing placebo surgery in research on refractory Parkinson's disease, Peter Clark succinctly states this view: “The researcher has an ethical responsibility to act in the best interest of subjects.”.

The possibilities of a realistic interpretation of quantum mechanics are investigated by means of a statistical analysis of experiments performed on the simplest type of quantum systems carrying spin or helicity. To this end, fundamental experiments, some new, for measuring polarization are reviewed and (re)analyzed. Theunsharp reality of spin is essential in the interpretation of some of these experiments and represents a natural motivation for recent generalizations of quantum mechanics to a theory incorporating effect-valued measures as unsharp observables and generalized (...) systems of imprimitivity.

Emotions are discrete, automatic responses to universally shared, culture-specific and individual-specific events. The emotion terms, such as anger, fear, etcetera, denote a family of related states sharing at least 12 characteristics, which distinguish one emotion family from another, as well as from other affective states. These affective responses are preprogrammed and involuntary, but are also shaped by life experiences.

What is 'praxis'? How do we study theology from its perspective? These are the main questions which this book seeks to answer.

The metaphor of space/place has always been crucial to theological discourse. Throughout its history, theology has expressed itself in spatial images correlative to its concomitant culture. The phenomenon of globalization makes possible a revolution in the concept of space/place. It is this transformation which we seek to examine in order to bear out some methodological consequences for theological reflection. This article consists in three parts. First, we explore the notions of space in two contemporary theorists of globalization – Anthony Giddens (...) and David Harvey. We have seen that both Giddens’ “empty spaces” and Harvey’s “compression of time and space”, even as they partly describe the present-day global situation, are also deficient if only considered individually. In a second step, we propose to integrate into the analytical framework Raymond Williams’ concept of “placeable social identities” as establishing a complementary relationship between Giddens and Harvey. In this powerful spatial metaphor, Williams has argued for the primacy of real “placeable” communities of peoples where meaning is constantly constructed and negociated. His assertion of identifiable settlements and rooted communal identities is an antidote to the often ideological talk of the high-speed movement and constantly shifting identities in globalization. But these are not nostalgic identities since in their borders, they constantly reshape their own meanings and valuations as they interact with contemporary global challenges. In a third move, we examine two spatial views of the church , two ways of doing theology) as response to globalization: Milbank’s “enclave” and Schreiter’s “World Church”. While Milbank’s discourse of the “difference” of the Christian traditions echoes the postmodern sensibilities of a globalized world, his concept of the Church as “enclave” also reminds us of a reactionary persecuted Church which hides behind its mantle the rhetoric of universalism characteristic of an isolated minority. Schreiter’s “World Church” is much more open; but his concern for “universality” and “catholicity” almost erases the asymmetry and disruption which the global culture has done to Two-Thirds of the world population. Beyond Milbank and Schreiter , we conclude by suggesting that Williams’ placeable social identities may thus provide a metaphor for theorizing spatiality in a global world that would be consistent with liberative theological methodology.

Detection of deception and confirmation of truth telling with conventional polygraphy raised a host of technical and ethical issues. Recently, newer methods of recording electromagnetic signals from the brain show promise in permitting the detection of deception or truth telling. Some are even being promoted as more accurate than conventional polygraphy. While the new technologies raise issues of personal privacy, acceptable forensic application, and other social issues, the focus of this paper is the technical limitations of the developing technology. Those (...) limitations include the measurement validity of the new technologies, which remains largely unknown. Another set of questions pertains to the psychological paradigms used to model or constrain the target behavior. Finally, there is little standardization in the field, and the vulnerability of the techniques to countermeasures is unknown. Premature application of these technologies outside of research settings should be resisted, and the social conversation about the appropriate parameters of its civil, forensic, and security use should begin.

Surveillance is a core function of all public health systems. Responses to the COVID-19 pandemic have deployed traditional public health surveillance responses, such as contact tracing and quarantine, and extended these responses with the use of varied technologies, such as the use of smartphone location data, data networks, ankle bracelets, drones, and big data analysis. Applying Foucault’s (1979) notion of the panopticon, with its twin focus on surveillance and self-regulation, as the preeminent form of social control in modern societies, we (...) examine the increasing levels of surveillance enacted during this pandemic and how people have participated in, and extended, this surveillance, self-regulation, and social control through the use of digital media. Consideration is given to how such surveillance may serve public health needs and/or political interests and whether the rapid deployment of these extensive surveillance mechanisms risks normalizing these measures so that they become more acceptable and then entrenched post-COVID-19.

Future robots should have common sense about the world in order to handle the problems they will encounter. A large part of this commonsense knowledge must be naive physics knowledge, since carrying out even the simplest everyday chores requires familiarity with physics laws. But how should one start codifying this knowledge? What kind of skills should be elicited from the experts (each and every one of us)? This paper will attempt to provide some hints by studying the mental models of (...) force and motion. (shrink)

Research has demonstrated that two types of affect have an influence on judgment and decision making: incidental affect (affect unrelated to a judgment or decision such as a mood) and integral affect (affect that is part of the perceiver’s internal representation of the option or target under consideration). So far, these two lines of research have seldom crossed so that knowledge concerning their combined effects is largely missing. To fill this gap, the present review highlights differences and similarities between integral (...) and incidental affect. Further, common and unique mechanisms that enable these two types of affect to influence judgment and choices are identified. Finally, some basic principles for affect integration when the two sources co-occur are outlined. These principles are discussed in relation to existing work that has focused on incidental or integral affect but not both. (shrink)

In two studies of a GO–NOGO task assessing sustained attention, we examined the effects of altering speed–accuracy trade-offs through instructions and auditory alerts distributed throughout the task. Instructions emphasizing accuracy reduced errors and changed the distribution of GO trial RTs. Additionally, correlations between errors and increasing RTs produced a U-function; excessively fast and slow RTs accounted for much of the variance of errors. Contrary to previous reports, alerts increased errors and RT variability. The results suggest that standard instructions for sustained (...) attention tasks, emphasizing speed and accuracy equally, produce errors arising from attempts to conform to the misleading requirement for speed, which become conflated with attention-lapse produced errors and auditory alerts have complex, and sometimes deleterious, effects on attention. We argue that instructions emphasizing accuracy provide a more precise assessment of attention lapses in sustained attention tasks. (shrink)
