This paper investigates the use of theories of mechanics to provide answers to questions in the metaphysics of spatial location and persistence. Investigating spatial location, I find that in classical physics bodies pertend the region of space at which they are exactly located, while a quantum system spans a region at which it is exactly located. Following this analysis, I present a ‘no-go’ result which shows that quantum mechanics restricts the available options for locational persistence theories in an interesting way: (...) it demonstrates that the spatiotemporal path of a persisting thing is discrete in time. This leads to unpalatable consequences for both perdurantists and endurantists. In particular, I argue that Butterfield's ‘anti-pointilliste’ perdurantism is ruled out, and show that endurantists relying on immanent causation run into trouble. I conclude by suggesting the revival of Whitehead's alternative mode of persistence called ‘reiteration.’. (shrink)

Much debate has ensued regarding the challenge to scientific realism provided by consideration of certain problematic episodes of theory change in the history of science. This paper contends that there is an interesting case which has been overlooked in this debate, namely the prediction of the positron by Dirac from his ‘hole’ theory, and its subsequent replacement by a theory which failed to contain a central, and essential, theoretical posit: the ‘Dirac sea’ of negative energy electrons. Accounting for this case (...) with the ‘divide and conquer’ strategy of contemporary scientific realism proves particularly troublesome, even for the structural realist. (shrink)

This article provides a new context for an established metaphysical debate regarding the problem of persistence. I contend that perdurance, a popular view about persistence which maintains that objects persist by having temporal parts, can be formulated in quantum mechanics due to the existence of a formal analogy between temporal and spatial location. However, this analogy fails due to a ‘no-go’ result which demonstrates that quantum systems cannot be said to have temporal parts in the same way that they have (...) spatial parts. Therefore, if quantum mechanics describes persisting physical objects then those objects cannot be said to perdure. (shrink)

Quantum mechanics has provided philosophers of science with many counterintuitive insights and interpretive puzzles, but little has been written about the role that time plays in the theory. One reason for this is the celebrated argument of Wolfgang Pauli against the inclusion of time as an observable of the theory, which has been seen as a demonstration that time may only enter the theory as a classical parameter. Against this orthodoxy I argue that there are good reasons to expect certain (...) kinds of 'time observables' to find a representation within quantum theory, including clock operators and event time operators, which provide predictions for the time at which a particular event occurs, such as the appearance of a dot on a luminescent screen. I contend that these time operators deserve full status as observables of the theory, and on reflection provide a uniquely compelling reason to expand the set of observables allowed by the standard formalism of quantum mechanics. In addition, I provide a novel association of event time operators with conditional probabilities, and propose a temporally extended form of quantum theory to better accommodate the time of an event as an observable quantity. This leads to a proposal to interpret quantum theory within an event ontology, inspired by Bertrand Russell's Analysis of Matter. On this basis I mount a defense of Russell's relational theory of time against a recent attack. (shrink)

In this paper I am concerned with analyzing in detail how ideas and expectations regarding the role of time in quantum theory arose and evolved in the early years of quantum mechanics. The general theme is that expectations which seemed reasonable from the point of view of matrix mechanics and Dirac's q-number formalism became implausible in light of Dirac-Jordan transformation theory, and were dashed by von Neumann's Hilbert space formalism which came to replace it. Nonetheless, I will identify two concerns (...) that remain relevant today, and which blunt the force of Hilgevoord's claim that the demand that time feature as an observable arose as the result of a simple conceptual error. (shrink)

In an event ontology, matter is 'made up of' events. This provides a distinctive foil to the standard view of a quantum state in terms of properties possessed by a system. Here I provide an argument against the standard view and suggest instead a way to conceive of quantum mechanics in terms of probabilities for the occurrence of events localized in space and time. To that end I construct an appropriate probability space for these events and give a way to (...) calculate them as conditional probabilities. I suggest that these probabilities can be usefully thought of as Lewisian objective chances. (shrink)

This paper provides a general method for defining a generalized quantum observable that supplies properly normalized conditional probabilities for the time of occurrence. This method treats the time of occurrence as a probabilistic variable whose value is to be determined by experiment and predicted by the Born rule. This avoids the problematic assumption that a question about the time at which an event occurs must be answered through instantaneous measurements of a projector by an observer, common to both Rovelli and (...) Oppenheim et al.. I also address the interpretation of experiments purporting to demonstrate the quantum Zeno effect, used by Oppenheim et al. to justify an inherent uncertainty for measurements of times. (shrink)

In this article I reply to Fleming׳s response to my ‘Time and quantum theory: a history and a prospectus.’ I take issue with two of his claims: (i) that quantum theory concerns the (potential) properties of eternally persisting objects; (ii) that there is an underdetermination problem for Positive Operator Valued Measures (POVMs). I advocate an event-first view which regards the probabilities supplied by quantum theory as probabilities for the occurrence of physical events rather than the possession of properties by persisting (...) objects. (shrink)

In this reply to Prof. Fleming's response to my `Time and Quantum Theory: A History and A Prospectus' I take issue with two of his claims: that quantum theory concerns the properties of eternally persisting objects; that there is a underdetermination problem for POVMs.

Ulrich Meyer's book The Nature of Time uses tense logic to argue for a `modal' view of time, which replaces substantial times with `ersatz times' constructed using conceptually basic tense operators. He also argues against Bertrand Russell's relationist theory, in which times are classes of events, and against the idea that relativity compels the integration of time and space. I find fault with each of these negative arguments, as well as with Meyer's purported reconstruction of empty spacetime from tense operators (...) and substantial spatial points. I suggest that Meyer's positive project is best conceived as an elimination of time in the mode of Julian Barbour's The End of Time. (shrink)

Russell's nonchalant response to Newman's apparently devastating critique of his structural realism presents a puzzle: if Russell conceded the point why did he not alter his theory or address the problem in print? I argue that Newman had merely pointed out an ambiguity in the formulation of Russell's theory in Analysis of Matter, and Russell already had the resources to avoid the problem through his contention that some relations are perceived. This concession gives his criterion of structural equivalence enough empirical (...) purchase to avoid Newman's triviality objection without the need to make stronger claims of knowledge of external relations than are present in Analysis of Matter. This provides a precise criterion of structural equivalence that explains exactly how the structural realist may escape Newman's objection by taking relations in intension. (shrink)

Big Ideas for Little Kids includes everything a teacher, a parent, or a college student needs to teach philosophy to elementary school children from picture books. Written in a clear and accessible style, the book explains why it is important to allow young children access to philosophy during primary-school education. Wartenberg also gives advice on how to construct a "learner-centered" classroom, in which children discuss philosophical issues with one another as they respond to open-ended questions by saying whether they agree (...) or disagree with what others have said.

This paper is an exposition and evaluation of the Agustín Rayo's views about the epistemology and metaphysics of mathematics, as they are presented in his book The Construction of Logical Space.

This volume is a study of the influence of Timaeus on the development of Western cosmology in three axial periods of European culture: Late Antiquity, Middle Ages and Renaissance.

Thomas Reid is now recognized as one of the towering figures of the Enlightenment. Best known for his published writings on epistemology and moral theory, he was also an accomplished mathematician and natural philosopher, as an earlier volume of his manuscripts edited by Paul Wood for the Edinburgh Reid Edition, Thomas Reid on the Animate Creation, has shown. The Correspondence of Thomas Reid collects all of the known letters to and from Reid in a fully annotated form. (...) Letters already published by Sir William Hamilton and others have been reedited, and roughly half of the letters included appear in print for the first time. Writing in 1802, Reid's disciple and biographer Dugald Stewart doubted that Reid's correspondence &"would be generally interesting.&" This collection proves otherwise, for the letters illuminate virtually every aspect of Reid's life and career and, in some instances, provide us with invaluable evidence about activities otherwise undocumented in his manuscripts or published works. Through his correspondence we can trace Reid's relations with contemporaries such as David Hume and his colleagues at both King's College, Aberdeen, and the University of Glasgow, as well as his engagement with the most controversial philosophical, scientific, and political issues of his day. If anything, the letters assembled here serve as the starting point for understanding Reid and his place in the Enlightenment. (shrink)

This book is a fiftieth anniversary republication of Thomas Nagel's "What Is It Like to Be a Bat?", a classic in the philosophy of mind. Through its argument for the irreducible subjectivity of consciousness, it played an essential role in making the study of consciousness a central part of philosophy, psychology, and neuroscience. It also spurred the now flourishing scientific attention to the consciousness of non-human creatures: mammals, birds, fish, mollusks, and insects. The book also includes a second essay (...) offering Nagel's more recent thoughts on the most promising positive response to the mind-body problem, as posed in the original essay. (shrink)

Thomas Hill, a leading figure in the recent development of Kantian moral philosophy, presents a set of essays exploring the implications of basic Kantian ideas for practical issues. The first part of the book provides background in central themes in Kant's ethics; the second part discusses questions regarding human welfare; the third focuses on moral worth-the nature and grounds of moral assessment of persons as deserving esteem or blame. Hill shows moral, political, and social philosophers just how valuable moral (...) theory can be in addressing practical matters. (shrink)

Respect, Pluralism, and Justice is a series of essays which sketches a broadly Kantian framework for moral deliberation, and then uses it to address important social and political issues. Hill shows how Kantian theory can be developed to deal with questions about cultural diversity, punishment, political violence, responsibility for the consequences of wrongdoing, and state coercion in a pluralistic society.

The word “emotion” has named a psychological category and a subject for systematic enquiry only since the 19th century. Before then, relevant mental states were categorised variously as “appetites,” “passions,” “affections,” or “sentiments.” The word “emotion” has existed in English since the 17th century, originating as a translation of the French émotion, meaning a physical disturbance. It came into much wider use in 18th-century English, often to refer to mental experiences, becoming a fully fledged theoretical term in the following century, (...) especially through the influence of two Scottish philosopher-physicians, Thomas Brown and Charles Bell. This article relates this intellectual and semantic history to contemporary debates about the usefulness and meaning of “emotion” as a scientific term. (shrink)

Nietzsche is often regarded as a paradigmatically anti-theoretical philosopher. Bernard Williams has said that Nietzsche is so far from being a theorist that his text “is booby-trapped not only against recovering theory from it, but, in many cases, against any systematic exegesis that assimilates it to theory.” Many would apply this view especially to Nietzsche’s moral philosophy. They would say that even when he is making positive normative claims, as against just criticizing existing morality, his claims have neither the content (...) nor the organization characteristic of moral theory.

For early modern metaphysician Anne Conway, the world comprises creatures. In some sense, Conway is a monist about creatures: all creatures are one. Yet, as Jessica Gordon-Roth has astutely pointed out, that monism can be understood in very different ways. One might read Conway as an ‘existence pluralist’: creatures are all composed of the same type of substance, but many substances exist. Alternatively, one might read Conway as an ‘existence monist’: there is only one created substance. Gordon-Roth has done the (...) scholarship a great favor by illuminating these issues in Conway. However, this article takes issue with Gordon-Roth's further view that Conway ‘oscillates’ between the extremes of existence pluralism and monism. In its place, I argue we should read Conway as a priority monist: the whole of creation is ontologically prior to its parts. (shrink)

Thomas Aquinas produced a voluminous body of work on moral theory, and much of that work is on virtue, particularly the status and value of the virtues as principles of virtuous acts, and the way in which a moral life can be organized around them schematically. Thomas Osborne presents Aquinas's account of virtue in its historical, philosophical and theological contexts, to show the reader what Aquinas himself wished to teach about virtue. His discussion makes the complexities of Aquinas's (...) moral thought accessible to readers despite the differences between Thomas's texts themselves, and the distance between our background assumptions and his. The book will be valuable for scholars and students in ethics, medieval philosophy, and theology. (shrink)

Glymour and Quine propose two different formal criteria for theoretical equivalence. In this paper we examine the relationships between these criteria.

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are still to be favoured over the (...) perceptual confidence view. (shrink)

Divided into three parts, this work is a record of the direction Kuhn was taking during the last two decades of his life. It consists of essays in which he refines the basic concepts set forth in "Structure"--Paradigm shifts, incommensurability, and the nature of scientific progress.

Socrates is one of the most important yet enigmatic philosophers of all time; his fame has endured for centuries despite the fact that he never actually wrote anything. In 399 B.C.E., he was tried on the charge of impiety by the citizens of Athens, convicted by a jury, and sentenced to death (ordered to drink poison derived from hemlock). About these facts there is no disagreement. However, as the sources collected in this book and the scholarly essays that follow them (...) show, several of even the most basic facts about these events were controversial in antiquity, and the questions persist today: How and why was Socrates brought to trial? Why did the jurors, members of the world's first democracy, find him guilty? When he was given an opportunity to escape execution, why did he refuse to do so and instead accept the punishment that he and his friends agreed was unjustly assigned to him? How exactly did Socrates die? Differences of opinion on these and other issues continue to arouse our curiosity and to challenge new generations of students and scholars. The Trial and Execution of Socrates: Sources and Controversies is the first work to collect in one place all of the major ancient sources on Socrates' death--those of both his critics and his defenders--as well as recent scholarly views. Part I includes new translations of Plato's Euthyphro, Apology, Crito, and the death scene from Phaedo, as well as other ancient sources that shed light on Socrates' trial and execution. Part II features some of the most influential recent scholarship on this historically momentous event with work by M. F. Burnyeat, Robert Parker, Mark L. McPherran, Thomas C. Brickhouse and Nicholas D. Smith, Richard Kraut, Christopher Gill, and Enid Bloch (whose essay is published here for the first time). Ideal for undergraduate surveys of ancient Greek philosophy and upper-level courses on Socrates and Socratic philosophy, this unique collection provides an unprecedented look into the many perplexing questions surrounding the trial and execution of this remarkable man.

Issues concerning patients' rights are at the center of bioethics, but the political basis for these rights has rarely been examined. In Bioethics in a Liberal Society: The Political Framework of Bioethics Decision Making , Thomas May offers a compelling analysis of how the political context of liberal constitutional democracy shapes the rights and obligations of both patients and health care professionals. May focuses on how a key feature of liberal society -- namely, an individual's right to make independent (...) decisions -- has an impact on the most important relational facets of health care, such as patients' autonomy and professionals' rights of conscience. Although a liberal political framework protects individual judgments, May asserts that this right is based on the assumption of an individual's competency to make sound decisions. May uses case studies to examine society's approach to medical decision making when, for reasons ranging from age to severe mental disorder, a person lacks sufficient competency to make independent and fully informed choices. To protect the autonomy of these vulnerable patients, May emphasizes the need for health care ethics committees and ethics consultants to help guide the decision-making process in clinical settings. Bioethics in a Liberal Society is essential reading for all those interested in understanding how bioethics is practiced within our society. (shrink)
