This brief, affordable text helps students to think critically, using examples from the weird claims and beliefs that abound in our culture to demonstrate the sound evaluation of any claim. It explains step-by-step how to sort through reasons, evaluate evidence, and tell when a claim is likely to be true. The emphasis is neither on debunking nor on advocating specific assertions, but on explaining principles of critical thinking that enable readers to evaluate claims for themselves. The authors focus on types (...) of logical arguments and proofs, making How to Think about Weird Things a versatile supplement for logic, critical thinking, philosophy of science, or any other science appreciation courses.

According to Eugenie Scott, methodological materialism---the view that science attempts to explain the world using material processes---does not imply philosophical materialism---the view that all that exists are material processes. Thus one can consistently be both a scientist and a theist. According to Phillip Johnson, however, methodological materialism presupposes philosophical materialism. Consequently, scientists are unable to see the cogency of supernatural explanations, like creationism. I argue that both Scott and Johnson are wrong: scientists are not limited to explaining tbe world using (...) material processes and science does not presuppose materialism. Thus scientists’ rejection of creationism is not irrational. (shrink)

This book is a unique introductory overview of decision theory. It is completely non-technical, without a single formula in the book. Written in a crisp and clear style it succinctly covers the full range of philosophical issues of rationality and decision theory, including game theory, social choice theory, prisoner's dilemma and much else. The book aims to expand the scope and enrich the foundations of decision theory. By addressing such issues as ambivalence, inner conflict, and the constraints imposed upon us (...) by our attachments to others, Frederic Schick reveals that our thinking is often more subtle than standard theories of rationality allow. Only a theory that respects that subtlety can illumine what is otherwise puzzling. The book contains many examples drawn from history and literature dealing with subjects such as love, war, friendship, and crime. (shrink)

This study defends the legitimacy of the Enlightenment project by way of its different realizations in the philosophies of Immanuel Kant and Friedrich Heinrich Jacobi. Today, Enlightenment as a cosmopolitan project with a global claim is often considered synonymous with Western chauvinism. The assertion of a universally binding reason is all too obviously inconsistent with the much-cited recognition of cultural differences. In contrast, it is the conviction brought forward in this book that an adequately understood Enlightenment is an unconditional right (...) of every person taking an active interest in a self-determined way of life. Only the realization of this conception of Enlightenment can provide the required space for the reciprocal recognition of human differences to freely unfold. (shrink)

Models are of central importance in many scientific contexts. The centrality of models such as inflationary models in cosmology, general-circulation models of the global climate, the double-helix model of DNA, evolutionary models in biology, agent-based models in the social sciences, and general-equilibrium models of markets in their respective domains is a case in point (the Other Internet Resources section at the end of this entry contains links to online resources that discuss these models). Scientists spend significant amounts of time building, (...) testing, comparing, and revising models, and much journal space is dedicated to interpreting and discussing the implications of models. In short, models are one of the principal instruments of modern science. (shrink)

Recently, some philosophers have argued that we should take quantification of any (finite) order to be a legitimate and irreducible, sui generis kind of quantification. In particular, they hold that a semantic theory for higher-order quantification must itself be couched in higher-order terms. Øystein Linnebo has criticized such views on the grounds that they are committed to general claims about the semantic values of expressions that are by their own lights inexpressible. I show that Linnebo’s objection rests on the assumption (...) of a notion of semantic value or contribution which both applies to expressions of any order, and picks out, for each expression, an extra-linguistic correlate of that expression. I go on to argue that higher-orderists can plausibly reject this assumption, by means of a hierarchy of notions they can use to describe the extra-lingustic correlates of expressions of different orders.

A commonly held idea regarding the nature of time is that the future is open and the past is fixed or closed. This article investigates the notion that there is an asymmetry in openness between the past and the future. The following questions are considered: How exactly is this asymmetry in openness to be understood? What is the relation between an open future and various ontological views about the future? Is an open future a branching future? What is the relation (...) between an open future and the question of whether contingent statements about the future are true or false? Is an open future compatible with a single determinate future? (shrink)

A number of physicists have recently been espousing what appears to be a strong form of subjective idealism. Clauser and Horne, professors of physics at Berkeley and Stonehill College, respectively, for example, report.

A conjunction of two hypotheses may provide a better explanation than either one of them individually, even if each already provides a good explanation on its own. An appropriate measure of explanatory power should reflect this, but none of the measures discussed in the literature do so because they only consider how much an explanatory hypothesis reduces our surprise at the evidence – which is problematic. This chapter introduces and defends a class of coherentist measures of explanatory power, and shows (...) that one particular such measure that combines different intuitions underlying the epistemological notion of coherence overcomes the aforementioned problems of surprise reduction measures.

Coherence considerations play an important role in science and in everyday reasoning. However, it is unclear what exactly is meant by coherence of information and why we prefer more coherent information over less coherent information. To answer these questions, we first explore how to explicate the dazzling notion of ``coherence'' and how to measure the coherence of an information set. To do so, we critique prima facie plausible proposals that incorporate normative principles such as ``Agreement'' or ``Dependence'' and then argue (...) that the coherence of an information set is best understood as an indicator of the truth of the set under certain conditions. Using computer simulations, we then show that a new probabilistic measure of coherence that combines aspects of the two principles above, but without strictly satisfying either principle, performs particularly well in this regard.

There is currently disagreement about whether the phenomenon of first-person, or de se, thought motivates a move towards special kinds of contents. Some take the conclusion that traditional propositions are unable to serve as the content of de se belief to be old news, successfully argued for in a number of influential works several decades ago.1 Recently, some philosophers have challenged the view that there exist uniquely de se contents, claiming that most of the philosophical community has been under the (...) grip of an attractive but unmotivated myth.2 At the very least, this latter group has brought into question the arguments in favor of positing special kinds of content for de se belief; I think they have successfully shown that these arguments are not as conclusive, or fully articulated, as many have taken them to be. In this paper I will address these challenges directly and I will present and defend an argument for the conclusion that the phenomenon of de se thought does indeed motivate the move to a special kind of content, content that is uniquely de se. First, I characterize a notion of de se belief that is neutral with respect to friends and foes of uniquely de se content. I then argue for a determination thesis relating de se belief to belief content: that there is no difference in de se belief without a difference in belief content. I argue that various proposals for rejecting this determination thesis are unsuccessful. In the last part of the paper, I employ this determination thesis to argue for the existence of a type of belief content that is uniquely de se. (shrink)

continent. 1.2 (2011): 141-144. This January, while preparing a new course, Robert Seydel was struck and killed by an unexpected heart attack. He was a critically under-appreciated artist and one of the most beloved and admired professors at Hampshire College. At the time of his passing, Seydel was on the brink of a major artistic and career milestone. His Book of Ruth was being prepared for publication by Siglio Press. His publisher describes the book as: “an alchemical assemblage that composes (...) the life of his alter ego, Ruth Greisman— spinster, Sunday painter, and friend to Joseph Cornell and Marcel Duchamp. Through collages, drawings, and journal entries from Ruth’s imagined life, Seydel invokes her interior world in novelistic rhythms.” This convergence of his professional triumph with the tragedy of his death makes now a particularly appropriate time to think about Robert Seydel and his work. This feature contains a selection of excerpts from Book of Ruth (courtesy of Siglio Press) alongside a pair of texts remembering him and giving critical and biographical insights into his art and his person. These texts, from a former student and a colleague respectively, were originally prepared for Seydel's memorial at Hampshire College and have since been revised for publication in continent. For more information on Book of Ruth, please visit the book's page at the Siglio Press website. —Ben Segal draughty R. * Lauren van Haaften-Schick 2011 “The most apt way to order Smithson's library is with the conjunction 'and'; science and religion; modernism and mass culture; what is present and what is missing.” —Alexander Alberro, 248 Robert Seydel's classes on collage and collecting immersed his students in a curious world of cabinets, oddities, exhaustive archives and obscure histories, explored always with critical rigor and a sincere eye for wonder. His office was a compendium of the ancient, mythic, potential and unworldy, where seemingly unrelated references were endlessly pulled, piled and fused in an ecstatic dance of hyper-annotation. The small room and all its contents overflowed with notes tucked in every margin and corner. Books coated the walls like a switchboard, anxious and humming, waiting for infinite links to be activated. William Blake's books of Job and Urizen summoned Greek mythology and the animal as metaphor, leading to 19th century cryptozoology and the cave paintings at Lascaux, Gaston Bachelard's description of the bird in his garden and Robert Rauschenberg's Canyon . Tracking archetypes and following tangential threads, new revelations and ancient narratives were compiled and ordered to form a new text, a bibliography as assemblage, portrait and poem. Robert's library—one of his many collections—is a portrait, an “artifact, collage of time, a token and remnant” (Seydel, 2007) He is humming with it still. The imagination of this room—of Robert—breathes through the pages of Book of Ruth, as every decision and detail unfolds to a cosmos. Allegory, invention, personal and art histories are entangled and leveled, rendering lived, perceived and absorbed experiences indistinguishable. Anonymous scraps discovered on the street or studio floor, careful clippings and drawn figures are chosen and animated through serendipitous destruction and whimsical, delicate positioning. A precise vocabulary of characters and terms erupts and collapses as personas and passers-by wave and whisper, “Every figure reveals aspects of the total form, which is open and green” (Seydel, 2007). The initials R.S. repeat, a nod to Robert's true family tree and further complicating identification. Robt, Robert's sometimes alter-ego, appears in myriad forms as a trickster “half-wit,” mercurial and skittish, or soft and worn thin. Saul is a solemn tinkerer, parsing the world and sometimes blind. Ruth, the speaker of the book, records and translates all, her voice wavering between poetic verse and a cryptic half-speech as complex as it is sparse. The rhythm of frayed edges sets time - the weight of the world and the lightness of paper. Robert wrote of his process, “Material is essential; scuffings carry history, which wanders throughout” (Seydel, 2007). Collectors, assemblers, sway between careful movements of selection and placement as they pull from the found world, mediating calculated and unconscious association to form a lexicon of gestures, symbols and allusion, the “artifacts of a life... the refuse and rejecta of days” (Seydel, 2007). These assembled fragments shift and chatter, at home in their homelessness, actors performing in their own lives, populating an invented world of similar orphans. Such accumulated, severed parts carry the injury of their cutting and retain the evidence of their source, binding loss to creation in a symbiosis of trauma and repair. Mourning and remembrance are deeply embedded in the histories and acts of such practices. Grievance, acceptance, and the fragility of life are conveyed in the 18th century allegorical arrangements of fetal specimens by Frederik Ruysch. A certain melancholy reverence colors Joseph Cornell's intimately tactile assemblages rendering the universe tangible in miniature, or made in devotion to unrequited loves. Preserved in stasis, these ghosts and idols are kept in a purgatory where fact and fiction, past and present are irrelevant distinctions. Catalogued and contained, the subject of loss is transferred to an artifact. Every thread, scrap and letter may be glued, gathered and placed in a museum, a tomb, a box, a page, ripe and open for possession. Holding on to grief and reveling in disrepair, we opt to be haunted. Forever unbalanced and in flux, the sublime of collage is its resolve to irresolution. For Robert, “Art, as creation and as sign of primary Imagination, is not objects but a state, a kind of fluid” (Seydel, 2007) Reflecting on his work, life, and death, I am drawn to my library and the myriad titles acquired through his inspiration. There is Daniel Spoerri's An Anecdoted Topography of Chance , Susan Stewart's On Longing , various Borges, Barthes, Perec, and especially Life: A User's Manual , which concludes that the perfect puzzle will have no solution. I think of the drawers of miscellaneous swallowed objects at the Mutter Museum, Ray Johnson coding the every day in riddles, Wallace Berman twisting tongues, and Susan Hiller laying every detail to bear. Collectors and makers working in endless cycles of observation, ingestion and display. Every gesture informs and is defined by others, every space is shaped by that which surrounds and fills it, the knot has an inner logic, the gigantic is not so different from the miniature, there is a world in every detail, and “All art is collage” (Seydel, 2011) These thoughts have molded my life, my art, and all the minutia that keep the two so profoundly intertwined; There is no difference between life and what we do with our time. “I write my life. I make me up.” What a gift to share this secret way of knowing the world, and to leave this knowledge for us to do with what we please. “Art begins in admiration” (Seydel, 2011) Lauren van Haaften-Schick is a curator, writer and artist based in New York.

Sura Levine on Robert Seydel If early on in his time at Hampshire College I was officially his “mentor,” Robert Seydel quickly became one of my great teachers. Over the years we talked about everything, from art, music, collage, and poetry, to campus politics, this latter far too often. It was always a sublime pleasure, if all too rarely done, to enter his apartment to look at his work in progress, to peruse his bookshelves where, inevitably, there were always new treats to examine. And, while he was working on his Book of Ruth , I was given the opportunity over the course of many meals at the Korean and other restaurants, to talk with him about image and poem ordering. To see how he thought through each comma, each juxtaposition across the gutters of the Book, was to watch a brilliant curator at work. Each day, I walk past his wonderful collaged portrait of Ruth, purchased, after much haggling, as a birthday present, a couple of years ago. And each day, I think how lucky I am to have known Robert as he produced this magnum opus. One of my greatest pleasures in 24 years at the College was to teach “The Collector” with Robert. One of my greatest regrets is that the magic we created together in the classroom will not, and cannot, be duplicated. Its various incarnations, its utter intelligence and magic, were all so deeply Robert’s. His was a mind that put poetry, philosophy, history of science, and history together with art, and art together with music. His intellect and eye were unparalleled. He introduced us to so many artists. He shared his fascination with the cabinets of curiosity of Aldrovandi, of Seba, and Peter the Great’s collection of fetal anomalies, as well as the Museum of Jurassic Technology in Los Angeles. Robert knew them all and so many more. He was a walking encyclopedia, his home a great archive. Arcane knowledge, perhaps, but oh so important for another of Robert’s heroes, the mid-20th century Belgian artist Marcel Broodthaers, whose name he invariably mispronounced as “Broadthayers.” In speaking his name, Robert would always look in my direction in a panic, and then he go on and maul it. I absolutely loved his various mispronunciations of French names and terms! “The Collector” was always filled with talented young artists, art historians, philosophers and writers who all came to understand the wondrous obsessions of the figure of the collector. Students in this course created dazzling projects each term. He always moved while looking and speaking. He read deeply, and commented on everyone’s work with wonderful generosity. Robert always found something to praise even in the least developed of projects. Robert inspired and mentored all of his students into making work that far exceeded their expectations—and ours. For those of you who were lucky enough to have been touched by or to have had an evaluation written by Robert, savor it, keep it, reread it, and share it. He loved working with you all; it is somehow fitting that he died while prepping yet another new course. Robert, it’s almost impossible to speak of you in the past tense, even though you left us a month ago. No doubt, if you knew about our gatherings and celebrations of you, you would be embarrassed that we are making a fuss over you; you always placed the focus on others rather than on yourself. This trait is exactly why so many people miss you now. We’re here to love you publicly as we all did privately for the eleven years you were among us. Robert, my very dear friend, you were an extraordinary artist—you were my brother of choice. My heart broke when yours did. I miss you profoundly. —Sura Levine, February 26, 2011 Sura Levine is a professor of art history at Hampshire College. Her field of specialty is 19th century Belgian and French art, particularly realism and impressionism. Having worked in museums for a number of years both prior to coming to the College, and, as guest curator and co-author of exhibition catalogues, she became particularly interested in the history of museum and trends in collecting. It was because of their shared interests that she and Robert Seydel developed their course, The Collector, which they co-taught for many years. (shrink)

Some writers have noted that valuation is often focused on foreseen changes. They say that we often don't value situations in terms of what we would have in them only but also in terms of the gains or losses that they offer us — that we then focus on departures from our status quo. They argue that such thinking conflicts with basic economic analysis, and also that it violates logic: they say that it is irrational. I agree that it seems (...) to be common. But is such a way of setting one's values a challenge to economics? And does it conflict with being rational? (shrink)

Levi’s work in decision theory has for many years been a major influence on the field. His writings have raised important new issues and opened new lines of inquiry. This collection of his papers brings out the range of his recent studies and the close bearing of his work on the work of others.

The relation of global supervenience is widely appealed to in philosophy. In slogan form, it is explained as follows: a class of properties A supervenes on a class of properties B if no two worlds differ in the distribution of A-properties without differing in the distribution of B-properties. It turns out, though, that there are several ways to cash out that slogan. Three different proposals have been discussed in the literature. In this paper, I argue that none of them is (...) adequate. Furthermore, I present a puzzle that reveals a tension in our concept of global supervenience. (shrink)

Bayesian epistemology addresses epistemological problems with the help of the mathematical theory of probability. It turns out that the probability calculus is especially suited to represent degrees of belief (credences) and to deal with questions of belief change, confirmation, evidence, justification, and coherence. Compared to the informal discussions in traditional epistemology, Bayesian epis- temology allows for a more precise and fine-grained analysis which takes the gradual aspects of these central epistemological notions into account. Bayesian epistemology therefore complements traditional epistemology; it (...) does not re- place it or aim at replacing it. (shrink)

Models are of central importance in many scientific contexts. The centrality of models such as the billiard ball model of a gas, the Bohr model of the atom, the MIT bag model of the nucleon, the Gaussian-chain model of a polymer, the Lorenz model of the atmosphere, the Lotka-Volterra model of predator-prey interaction, the double helix model of DNA, agent-based and evolutionary models in the social sciences, or general equilibrium models of markets in their respective domains are cases in point. (...) Scientists spend a great deal of time building, testing, comparing and revising models, and much journal space is dedicated to introducing, applying and interpreting these valuable tools. In short, models are one of the principal instruments of modern science. -/- Philosophers are acknowledging the importance of models with increasing attention and are probing the assorted roles that models play in scientific practice. The result has been an incredible proliferation of model-types in the philosophical literature. Probing models, phenomenological models, computational models, developmental models, explanatory models, impoverished models, testing models, idealized models, theoretical models, scale models, heuristic models, caricature models, didactic models, fantasy models, toy models, imaginary models, mathematical models, substitute models, iconic models, formal models, analogue models and instrumental models are but some of the notions that are used to categorize models. While at first glance this abundance is overwhelming, it can quickly be brought under control by recognizing that these notions pertain to different problems that arise in connection with models. For example, models raise questions in semantics (what is the representational function that models perform?), ontology (what kind of things are models?), epistemology (how do we learn with models?), and, of course, in philosophy of science (how do models relate to theory?; what are the implications of a model based approach to science for the debates over scientific realism, reductionism, explanation and laws of nature?).

De se attitudes seem to play a special role in action and cognition. This raises a challenge to the traditional way in which mental attitudes have been understood. In this chapter, we review the case for thinking that de se attitudes require special theoretical treatment and discuss various ways in which the traditional theory can be modified to accommodate de se attitudes.

Among the questions to be raised under the heading of “personal identity” are these: “What are we?” (fundamental nature question) and “Under what conditions do we persist through time?” (persistence question). Against the dominant neo-Lockean approach to these questions, the view known as animalism answers that each of us is an organism of the species Homo sapiens and that the conditions of our persistence are those of animals. Beyond describing the content and historical background of animalism and its rivals, this (...) entry explores some of the arguments for and objections to this controversial account of our nature and persistence.

This comprehensive new book introduces the core history of phenomenology and assesses its relevance to contemporary psychology, philosophy of mind, and cognitive science. From critiques of artificial intelligence research programs to ongoing work on embodiment and enactivism, the authors trace how phenomenology has produced a valuable framework for analyzing cognition and perception, whose impact on contemporary psychological and scientific research, and philosophical debates continues to grow. The first part of _An Introduction to Phenomenology_ is an extended overview of the history (...) and development of phenomenology, looking at its key thinkers, focusing particularly on Husserl, Heidegger and Merleau-Ponty, as well as its cultural and intellectual precursors. In the second half Chemero and Käufer turn their attention to the contemporary interpretations and uses of phenomenology in cognitive science, showing that phenomenology is a living source of inspiration in contemporary interdisciplinary studies of the mind. Käufer and Chemero have written a clear, jargon-free account of phenomenology, providing abundant examples and anecdotes to illustrate and to entertain. This book is an ideal introduction to phenomenology and cognitive science for the uninitiated, as well as for philosophy and psychology students keen to deepen their knowledge. (shrink)

What are we? What is the nature of the human person? Animalism has a straightforward answer to these long-standing philosophical questions: we are animals. After being ignored for a long time in philosophical discussions of our nature, this idea has recently gained considerable support in metaphysics and philosophy of mind. Containing mainly new papers as well as two highly important articles that were recently published elsewhere, this volume's contributors include both emerging voices in the debate and many of those who (...) have been instrumental in shaping it. Some of their contributions defend animalism, others criticize it, still others explore its more general implications. The book also contains a substantial introduction by the editors explaining what animalism is, identifying leading issues that merit attention, and highlighting many of the issues that the contributors have raised.

In the opinion of most philosophers, the capacity to entertain I-thoughts is grounded on a basic capacity to self-consciousness. It is because a creature has a concept of herself that she is able to say “I”. The aim of that book is to reverse the order of dependence and to show that the capacity to form I-thoughts is the primitive aptitude that transforms an impersonal consciousness into a Self.

Conditionals pervade every aspect of our thinking, from the mundane and everyday such as ‘if you eat too much cheese, you will have nightmares’ to the most fundamental concerns as in ‘if global warming isn’t halted, sea levels will rise dramatically’. Many decades of research have focussed on the semantics of conditionals and how people reason from conditionals in everyday life. Here it has been rather overlooked how we come to such conditionals in the first place. In many cases, they (...) are learned through testimony: someone warns us about the ill-effects of cheese. Any full account of the conditional must consequently incorporate such learning. Here, we provide a new formal account of belief change in response to a testimonial conditional. (shrink)

In a conflict between two people, one person wants one thing and the other wants something else and they think they can't both have what they want. Suppose that what they want can only be the outcome of some joint action. Adam must do either y or z and Eve either y ' or z ' – here y -and- y ' would be one joint action, y -and- z ' would be another, and so on. Adam wants the outcome (...) of his doing z while Eve is doing y '. Eve wants the outcome of her doing z ' while Adam is doing y. Each thinks that these outcomes can't both be had. (shrink)

" Le normal a pris la relève de l'ancestral ". C'est en ces termes que Michel Foucault salua l'avènement d'une nouvelle ère, celle des disciplines - moment où les sujets cessent de s'identifier par leurs généalogies et leurs positions dans un système d'alliances, par des mécanismes historico-rituels, mais sont plutôt voués à l'interminable hantise de la norme, à ne plus se connaître et se reconnaître que par le détour de l'altérité de l'anormal : voués à ne ressaisir leur identité et (...) à n'être auprès d'eux-mêmes qu'au plus proche du spectre inquiétant de ce tout autre qu'ils repoussent au plus loin. Alors, l'enfance de l'homme n'est plus la mémoire de son innocence perdue, mais la forme première de son insoumission ; le primitif n'est plus celui qui, depuis l'autre rive d'un quelconque voyage, lui fait signe vers le mirage de sa bonté native, mais celui qui indique, sous les espèces de la plus honteuse barbarie, le danger qu'il représente pour sa propre race ; et la folie n'est plus le masque grotesque ou sublime d'un au-delà de la raison, mais le miroir tendu de sa propre faiblesse. Car, si le temps est venu où " l'homme calculable " a remplacé " l'homme mémorable ", il n'en reste pas moins que le travail de la norme ne consiste pas, comme on le croit trop souvent, à produire un effet d'uniformisation sociale, mais fait bien plutôt jouer un complexe système de codage différentiel des conduites, à l'intérieur duquel nous sommes pris et advenons comme sujets. Pour autant qu'il engage notre mode d'être de sujets modernes, il nous appartient donc d'explorer ce code étrange et familier : c'est la tâche que se fixe l'auteur, à partir de l'un des concepts-clé de l'œuvre de Foucault.

This entry sketches the theory of personal identity that has come to be known as animalism. Animalism’s hallmark claim is that each of us is identical with a human animal. Moreover, animalists typically claim that we could not exist except as animals, and that the (biological) conditions of our persistence derive from our status as animals. Prominent advocates of this view include Michael Ayers, Eric Olson, Paul Snowdon, Peter van Inwagen, and David Wiggins.

There is a long philosophical tradition of addressing questions in philosophy of science and epistemology by means of the tools of Bayesian probability theory (see Earman (1992) and Howson and Urbach (1993)). In the late '70s, an axiomatic approach to conditional independence was developed within a Bayesian framework. This approach in conjunction with developments in graph theory are the two pillars of the theory of Bayesian Networks, which is a theory of probabilistic reasoning in artificial intelligence. The theory has been (...) very successful over the last two decades and has found a wide array of applications ranging from medical diagnosis to safety systems for hazardous industries. (shrink)

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

In this paper I consider two strategies for providing tenseless truth-conditions for tensed sentences: the token-reflexive theory and the date theory. Both theories have faced a number of objections by prominent A-theorists such as Quentin Smith and William Lane Craig. Traditionally, these two theories have been viewed as rival methods for providing truth-conditions for tensed sentences. I argue that the debate over whether the token-reflexive theory or the date theory is true has arisen from a failure to distinguish between conditions (...) for the truth of tensed tokens and conditions for the truth of propositions expressed by tensed tokens. I demonstrate that there is a true formulation of the token-reflexive theory that provides necessary and sufficient conditions for the truth of tensed tokens, and there is a true formulation of the date theory that provides necessary and sufficient conditions for the truth of propositions expressed by tensed tokens. I argue that once the views are properly formulated, the A-theorist’s objections fail to make their mark. However, I conclude by claiming that even though there is a true formulation of the token-reflexive theory and a true formulation of the date theory, the New B-theory nonetheless fails to provide a complete account of the truth and falsity of tensed sentences.

The Problem of Old Evidence has troubled Bayesians ever since Clark Glymour first presented it in 1980. Several solutions have been proposed, but all of them have drawbacks and none of them is considered to be the definite solution. In this article, I propose a new solution which combines several old ideas with a new one. It circumvents the crucial omniscience problem in an elegant way and leads to a considerable confirmation of the hypothesis in question.

This book successfully achieves to serve two different purposes. On the one hand, it is a readable physics-based introduction into the philosophy of science, written in an informal and accessible style. The author, himself a professor of physics at the University of Notre Dame and active in the philosophy of science for almost twenty years, carefully develops his metatheoretical arguments on a solid basis provided by an extensive survey along the lines of the historical development of physics. On the other (...) hand, this book supplies one long argument for Cushing´s own attitude in the philosophy of science. While former studies of the author, from which this book draws in part, focused each on one special episode in the history of science, this book gathers case material from many different parts of physics and epochs. The main goal of this book is ”to impress upon the reader the essential and ineliminable role that philosophical considerations have played in the actual practice of science” (p. xv). (shrink)

This paper reviews four leading strategies for addressing the problem of material constitution, along with some of the prominent objections faced by each approach. Sections include (1) "The Orthodox View: Coincident Objects," (2) "Dominant Kinds," (3) "Nihilism," (4) "Revising the Logic of Identity," and (5) "Future Research." Also included is an annotated bibliography.

The proper evaluation of a theory's virtues seems to require taking into account what the theory is indirectly or implicitly committed to, in addition to what it explicitly says. Most extant proposals for criteria of theory choice in the literature spell out the relevant notion of implicit commitment via some notion of entailment. I show that such criteria behave implausibly in application to theories that differ over matters of entailment. A recent defence by Howard Peacock of such a criterion against (...) this objection is examined and rejected. I go on to a develop a better proposal on which, roughly speaking, a theory is counted committed to a claim if and only if its best fully explicit extension is explicitly committed to the claim. Such extensions in turn are evaluated by ordinary standards of theory choice adapted to the case of theories assumed to articulate their intended content in a fully explicit fashion. (shrink)

I consider whether the self-ascription theory can succeed in providing a tenseless (B-theoretic) account of tensed belief and timely action. I evaluate an argument given by William Lane Craig for the conclusion that the self-ascription account of tensed belief entails a tensed theory (A-theory) of time. I claim that how one formulates the selfascription account of tensed belief depends upon whether one takes the subject of selfascription to be a momentary person-stage or an enduring person. I provide two different formulations (...) of the self-ascription account of tensed belief, one that is compatible with a perdurantist account of persons and the other that is compatible with an endurantist account of persons. I argue that a self-ascription account of tensed beliefs for enduring subjects most plausibly involves the self-ascription of relations rather than properties. I argue that whether one takes the subject of self-ascription to be a momentary personstage or an enduring person, the self-ascription theory provides a plausible B-theoretic account of how tensed belief and timely action are possible.

When do objects at different times compose a further object? This is the question of diachronic composition. The universalist answers, ‘under any conditions whatsoever’. Others argue for restrictions on diachronic composition: composition occurs only when certain conditions are met. Recently, some philosophers have argued that restrictions on diachronic compositions are motivated by our best physical theories. In Persistence and Spacetime and elsewhere, Yuri Balashov argues that diachronic compositions are restricted in terms of causal connections between object stages. In a recent (...) article, Nikk Effingham argues that the standard objections to views that endorse restrictions on composition do not apply to a view that restricts composition according to compliance with the laws of nature. On the face of it, such restrictions on diachronic composition preserve our common-sense ontology while eliminating from it scientifically revisionary objects that travel faster than the speed of light. I argue that these attempts to restrict diachronic composition by appealing to either causal or nomological constraints face insurmountable difficulties within the context of special relativity. I discuss how the universalist should best respond to Hudson’s argument for superluminal objects, and in doing so, I present and defend a new sufficient condition for motion that does not entail that such objects are in superluminal motion. 1 Introduction2 Diachronic Composition3 Diachronic Composition and Superluminal Objects4 Restricting Diachronic Composition5 Causal and Nomological Restrictions on Composition in a Relativistic Context6 Superluminal Objects and Motion7 Conclusion.

In this paper I examine an argument that has been made by Patrick Grim for the claim that de se knowledge is incompatible with the existence of an omniscient being. I claim that the success of the argument depends upon whether it is possible for someone else to know what I know in knowing (F), where (F) is a claim involving de se knowledge. I discuss one reply to this argument, proposed by Edward Wierenga, that appeals to first-person propositions and (...) argue that this response is unsuccessful. I then consider David Lewis’s theory of de se attitudes involving the self-ascription of properties. I claim that, according to this theory, there are two senses in which someone else can know what I know in knowing (F). I then argue that the second sense allows for the compatibility of de se knowledge with the existence of an omniscient being. (shrink)
