BioPortal is a Web portal that provides access to a library of biomedical ontologies and terminologies developed in OWL, RDF(S), OBO format, Protégé frames, and Rich Release Format. BioPortal functionality, driven by a service-oriented architecture, includes the ability to browse, search and visualize ontologies (Figure 1). The Web interface also facilitates community-based participation in the evaluation and evolution of ontology content.

The National Center for Biomedical Ontology is a consortium that comprises leading informaticians, biologists, clinicians, and ontologists, funded by the National Institutes of Health (NIH) Roadmap, to develop innovative technology and methods that allow scientists to record, manage, and disseminate biomedical information and knowledge in machine-processable form. The goals of the Center are (1) to help unify the divergent and isolated efforts in ontology development by promoting high quality open-source, standards-based tools to create, manage, and use ontologies, (2) to create (...) new software tools so that scientists can use ontologies to annotate and analyze biomedical data, (3) to provide a national resource for the ongoing evaluation, integration, and evolution of biomedical ontologies and associated tools and theories in the context of driving biomedical projects (DBPs), and (4) to disseminate the tools and resources of the Center and to identify, evaluate, and communicate best practices of ontology development to the biomedical community. Through the research activities within the Center, collaborations with the DBPs, and interactions with the biomedical community, our goal is to help scientists to work more effectively in the e-science paradigm, enhancing experiment design, experiment execution, data analysis, information synthesis, hypothesis generation and testing, and understand human disease.

The National Center for Biomedical Ontology is now in its seventh year. The goals of this National Center for Biomedical Computing are to: create and maintain a repository of biomedical ontologies and terminologies; build tools and web services to enable the use of ontologies and terminologies in clinical and translational research; educate their trainees and the scientific community broadly about biomedical ontology and ontology-based technology and best practices; and collaborate with a variety of groups who develop and use ontologies and (...) terminologies in biomedicine. The centerpiece of the National Center for Biomedical Ontology is a web-based resource known as BioPortal. BioPortal makes available for research in computationally useful forms more than 270 of the world's biomedical ontologies and terminologies, and supports a wide range of web services that enable investigators to use the ontologies to annotate and retrieve data, to generate value sets and special-purpose lexicons, and to perform advanced analytics on a wide range of biomedical data.

The Plant Ontology (PO) (http://www.plantontology.org) (Jaiswal et al., 2005; Avraham et al., 2008) was designed to facilitate cross-database querying and to foster consistent use of plant-specific terminology in annotation. As new data are generated from the ever-expanding list of plant genome projects, the need for a consistent, cross-taxon vocabulary has grown. To meet this need, the PO is being expanded to represent all plants. This is the first ontology designed to encompass anatomical structures as well as growth and developmental stages (...) across such a broad taxonomic range. While other ontologies such as the Gene Ontology (GO) (The Gene Ontology Consortium, 2010) or Cell Type Ontology (CL) (Bard et al., 2005) cover all living organisms, they are confined to structures at the cellular level and below. The diversity of growth forms and life histories within plants presents a challenge, but also provides unique opportunities to study developmental and evolutionary homology across organisms.

A wide variety of ontologies relevant to the biological and medical domains are available through the OBO Foundry portal, and their number is growing rapidly. Integration of these ontologies, while requiring considerable effort, is extremely desirable. However, heterogeneities in format and style pose serious obstacles to such integration. In particular, inconsistencies in naming conventions can impair the readability and navigability of ontology class hierarchies, and hinder their alignment and integration. While other sources of diversity are tremendously complex and challenging, agreeing (...) a set of common naming conventions is an achievable goal, particularly if those conventions are based on lessons drawn from pooled practical experience and surveys of community opinion. We summarize a review of existing naming conventions and highlight certain disadvantages with respect to general applicability in the biological domain. We also present the results of a survey carried out to establish which naming conventions are currently employed by OBO Foundry ontologies and to determine what their special requirements regarding the naming of entities might be. Lastly, we propose an initial set of typographic, syntactic and semantic conventions for labelling classes in OBO Foundry ontologies. Adherence to common naming conventions is more than just a matter of aesthetics. Such conventions provide guidance to ontology creators, help developers avoid flaws and inaccuracies when editing, and especially when interlinking, ontologies. Common naming conventions will also assist consumers of ontologies to more readily understand what meanings were intended by the authors of ontologies used in annotating bodies of data. (shrink)

A review of Chris Tucker's collection of papers on phenomenal conservatism.

In 'Literature Suspends Death: Sacrifice and Storytelling in Kierkegaard, Kafka and Blanchot' Chris Danta takes Genesis 22 as the starting point for an investigation of the role of literary imagination. His aim is to read the Genesis story from a literary-theoretical perspective in order to show how it can 'illuminate the secular situation of the literary writer.' To do this, Danta stages a fruitful confrontation between Søren Kierkegaard as defender of religion and inwardness and Franz Kafka and Maurice Blanchot (...) as defenders of literature. In this review, three important points in this confrontation are highlighted. 1. The problem of identification. 2. The moment of substitution. 3. The spectrality of the writer. (shrink)

The Philosopher Queen: Feminist Essays on War, Love, and Knowledge. By Chris Cuomo. Lanham, Md.: Rowman and Littlefield Publishers, Inc., 2003. The Philosopher Queen is a powerful illustration of what Cherríe Moraga calls a "theory in the flesh." That is, theorizing from a place where "physical realities of our lives—our skin color, the land or concrete we grow up on, our sexual longings—all fuse to create a politic [and, I would add, an ethics, spirituality, and epistemology] born out of (...) necessity" (Moraga 21). Cuomo's theory in the flesh combines standard philosophical essays with personal narratives and invites us to do philosophy from this joyful and witty place. Readers are invited to reframe and reexamine war, science, gender, sexuality, race, ecology, knowledge, and politics in a voice that is fearless, funny, faithful, and feminist—one that disrupts common understandings of how philosophy ought to be done. Instead philosophy should help us to "negotiate a wild, wicked world, and to provide some understanding of being and existence. The best philosophy aims to promote good and to produce knowledge, and therefore enable flourishing" (xi). Accepted philosophical approaches alone are inadequate. Life's challenges resist formulaic solutions. Knowledge is not always produced through neat deductions: truths are partial, power divides, stomachs growl, hearts are broken, and emotions influence...

It is now more than twenty years since Knight (1987) first presented his paradigm-shifting theory of how and why the ‘human revolution’ occurred — and had to occur — in modern humans who, as climates dried under ice age conditions and African rainforests shrank, found themselves surrounded by vast prairies and savannahs, with rich herds of game animals roaming across them. The temptation for male hunters, far from any home base, to eat the best portions of meat at the kill (...) site — as do other social carnivores — called for strong measures from human females, who were paying the heavy metabolic and physical costs of bearing large-brained but helpless children. Even in the modern west, with well stocked supermarkets, a pregnant or lactating woman can lose ten percent of the dry weight of her brain, because developing babies demand dietary lipids for brain growth (Horrobin, 1998). Hence the idea of the menstrual sex strike, designed to force males to deliver their kills entirely into the hands of women for cooking and distribution—a practice common in foraging communities to this day.

This study firstly addresses three threads in Chris Marker’s work – theology, Marxism, and Surrealism – through a mapping of the work of both Giorgio Agamben and Jacques Derrida onto the varied production of his film and photographic work. Notably, it is late Agamben and late Derrida that is utilized, as both began to exit so-called post-structuralism proper with the theological turn in the late 1980s and early 1990s. It addresses these threads through the means to ends employed and (...) as ends proper (as production of semi-autonomous works that also, paradoxically, index a much larger field of inquiry and theoretical praxis). It is perhaps French “schizophrenia” regarding theological versus political agency that best accounts for the sardonic deployment of irony and humor in Marker’s work in the face of Big History. Such means to ends (plus a subtle anti-intellectualism vis-à-vis fashionable academic trends) tend to underscore the severity and ultimate sincerity of Marker’s overall cultural-political project. -/- Dossier Chris Marker is also a study of a late-modern chiasmus, impersonal-personal agency, as it comes to expression in the works of Marker, as the dynamic interplay of political and subjective agency. As chiasmus, the complementary halves of this often-apocalyptic dynamis (a semi-catastrophic, temporal or historical force-field) also – arguably – secretly agree to meet, through the work of art, in the futural (problematized in contemporary French post-phenomenological and post-post-structuralist theory as “the event).” Consistent with the classical figure of concordia discors, Marker resolves these irreducible warring aspects of life experience in an atemporal and ahistorical moment that inhabits the work of art from its inception. This redemptive aspect in art is also the ultimate gesture of the artwork as autonomous subject and “mask” (or “screen”) for forces that reside beyond the frame of the image or work, as its proverbial Other, or within the frame, as other to that Other. -/- Despite the complications of the as-yet unresolved post-modern condition (its nihilist-relativist bias), and its similar, mostly circular concerns with the image and/or media, Marker’s work is clearly not post-modern. In fact, when tested against immemorial cultural epiphenomena, that work withstands all attempts at categorization and/or art-historical analysis proper. It remains unassimilable to the post-modern cause ... What emerges, upon closer examination, and through rigorous re-contextualization, is the prescient force of Marker’s works toward that futural state buried in art that is also “theological,” versus atheological, and heedlessly anterior to cultural politics per se. -/- In the case of Marker, this age-old or immemorial “thing-in-itself” (the artwork as image of world-chiasmus) finds its foremost or penultimate formation in his very-still photography – the singular images that are also the building blocks for his renowned ciné-essays. Not without irony, this same austere, reductive force of the still image (as form of proscription) also inhabits the more complex, synthetic works (or montages) that he has formulated and presented “dramatically,” here and there, through the often-sketchy apparatuses of his new-media experiments, as of the late 1980s. Ultimately, this world-image as chiasmus was always present within his earliest literary projects, from the 1940s forward – most especially in books and essays, with or without actual images. -/- Marker’s “return” to photography (to exhibiting still photography in galleries), in the late 2000s, is in many ways a return to the singular object of the artist-critic’s desire; the image in/for itself, while that image – endlessly troubled or interrogated for decades – continues to speak “in tongues” anyway, often against, or oblivious to, the voice of the author/artist/narrator. -/- Marker is a High Romantic Christian Marxist. The “Christic” aspect is rightly well-hidden, but emerges when the eschatological versus historical center of his work is exposed (the existential-metaphysical fuse such as also inhabits the works of Caravaggio), and when his early years are examined in light of his later and/or final years. Marker’s semi-personal/semi-impersonal apocalyptic vision is writ large in diverse works that cross decades, figuring a redemptive, world-shattering formation of art as pleroma. (shrink)

In different papers, David Liggins and Chris Daly tell philosophers what they should not do. There is no sign of them withdrawing any of these prohibitions, but I show that they fail to be consistent when asserting them. The inconsistency concerns when a philosopher should defer to the empirical findings of science.

David Liggins and Chris Daly have argued against a recent trend in which some philosophical debate or other is said to be settled by claims from a discipline other than philosophy, because claims from that discipline entail a position on the debate and any claims from that discipline have greater authority than any philosophical claims when the aim is to extend our knowledge. They label this trend deferentialism. This paper presents a dilemma for their argument.

Critical discussion of Chris Hill's perceptual theory of pain.

Chris Marker’s portrait of Alexandre Medvedkine in the 1993 film Le tombeau d’Alexandre/The Last Bolshevik is highly instructive of his own relationship to Soviet cinema. Most especially, this difficult or troubled rapport with the antecedents to cinéma vérité in the West (and its protean formal properties, in terms of structure and often satirical-critical commentary) comes forth in the figures he assembles to comment upon Medvedkine’s life work. When Medvedkine’s Scast’e (Le Bonheur/Happiness) (1934) leaked to the West (c.1967), sent like (...) an “SOS” in multiple bottles to various film archives (one by one from deep within the Soviet film world), Marker and SLON received a copy by way of Jacques Ledoux (curator of the Cinémathèque Royale de Belgique, in Belgium). The film opened the floodgates of a retrospective survey of Soviet filmmaking repressed and forgotten other than by remote and distant figures (partisans) who somehow survived the Stalinist purges of the 1930s.

This paper evaluates an argument for the conclusion that in order to produce a viable objection to a particular error theory, the objection must not be applicable to any error theory. The reason given for this conclusion is that error theories about some discourses are uncontroversial. But the examples given of uncontroversial error theories are not good ones, nor do there appear to be other examples available.

Gender classifications often are controversial. These controversies typically focus on whether gender classifications align with facts about gender kind membership: Could someone really be nonbinary? Is Chris Mosier (a trans man) really a man? I think this is a bad approach. Consider the possibility of ontological oppression, which arises when social kinds operating in a context unjustly constrain the behaviors, concepts, or affect of certain groups. Gender kinds operating in dominant contexts, I argue, oppress trans and nonbinary persons in (...) this way: they marginalize trans men and women and exclude nonbinary persons. As a result, facts about membership in dominant gender kinds should not settle gender classification practices. (shrink)

The category of sympathy marks a number of basic divisions in early modern approaches to action explanations, whether for human agency or for change in the wider natural world. Some authors were critical of using sympathy to explain change. They call such principles “unintelligible” or assume they involve “mysterious” action at a distance. Others, including Margaret Cavendish, Anne Conway, and Gottfried Wilhelm Leibniz, appeal to sympathy to capture natural phenomena, or to supply a backbone to their metaphysics. Here I discuss (...) how concerns about sympathetic actions form at least a partial background for differing seventeenth-century conceptions of what it is to explain action. I argue that critics of sympathy generally insist on an “atomistic” approach to action explanation, which makes primitively relational phenomena come out as problematic. Proponents of sympathy, by contrast, allow for a more holistic approach to action explanation, which allows for such basic connections. Hence, divergent attitudes toward sympathetic action in part explain differences in approaches to explanation. I conclude by showing how some of these core concerns fade into the background when in the eighteenth-century sympathy gets psychologised and individualised. (shrink)

Looking out the window, I see that it's raining outside. Do I know that it’s raining outside? According to proponents of the Entailment Thesis, I do. If I see that p, I know that p. In general, the Entailment Thesis is the thesis that if S perceives that p, S knows that p. But recently, some philosophers (McDowell 2002, Turri 2010, Pritchard 2011, 2012) have argued that the Entailment Thesis is false. On their view, we can see p and not (...) know that p. In this paper, I argue that their arguments are unsuccessful. (shrink)

Many contemporary philosophers rate error theories poorly. We identify the arguments these philosophers invoke, and expose their deficiencies. We thereby show that the prospects for error theory have been systematically underestimated. By undermining general arguments against all error theories, we leave it open whether any more particular arguments against particular error theories are more successful. The merits of error theories need to be settled on a case-by-case basis: there is no good general argument against error theories.

Just as theory of representation is deficient if it can’t explain how misrepresentation is possible, a theory of computation is deficient if it can’t explain how miscomputation is possible. Nonetheless, philosophers have generally ignored miscomputation. My primary goal in this paper is to clarify both what miscomputation is and how to adequately explain it. Miscomputation is a special kind of malfunction: a system miscomputes when it computes in a way that it shouldn’t. To explain miscomputation, you must provide accounts of (...) computational behavior, computational norms, and how computational behavior can deviate from computational norms. A secondary goal of this paper is to defend an (quasi-)individualist, mechanistic theory of miscomputation. Computational behavior is narrowly individuated. Computational norms are widely individuated. A system miscomputes when its behavior manifests a narrow computational structure that the widely individuated norms say that it should not have.

Subjective theories of well-being claim that how well our lives go for us is a matter of our attitudes towards what we get in life rather than the nature of the things themselves.

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...) of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

Geography, as a discipline, has provided significant leadership in explicating the history and cultural construction of human and nonhuman animal relations, as well as their gendered and racialized character and their economic embeddedness.

The struggles between groups to create their “places,” livelihoods, and future visions also will be struggles (...) to impose particular narratives and representations as the correct interpretation.

Contemporary theories of consciousness are based on widely different concepts of its nature, most or all of which probably embody aspects of the truth about it. Starting with a concept of consciousness indicated by the phrase “the feeling of what happens” (the title of a book by Antonio Damásio), we attempt to build a framework capable of supporting and resolving divergent views. We picture consciousness in terms of Reality experiencing itself from the perspective of cognitive agents. Each conscious experience is (...) regarded as composed of momentary feeling events that are combined by recognition and evaluation into extended conscious episodes that bind cognitive contents with a wide range of apparent durations (0.1 secs to 2 or more secs, for us humans, depending on circumstances and context). Three necessary conditions for the existence of consciousness are identified: a) a ground of Reality, envisaged as an universal field of potentiality encompassing all possible manifestations, whether material or 'mental'; b) a transitional zone, leading to; c) a manifest world with its fundamental divisions into material, 'informational' and quale-endowed aspects. We explore ideas about the nature of these necessary conditions, how they may relate to one another and whether our suggestions have empirical implications. (shrink)

The doctrine of permanent sovereignty over natural resources is a hugely consequential one in the contemporary world, appearing to grant nation-states both jurisdiction-type rights and rights of ownership over the resources to be found in their territories. But the normative justification for that doctrine is far from clear. This article elucidates the best arguments that might be made for permanent sovereignty, including claims from national improvement of or attachment to resources, as well as functionalist claims linking resource rights to key (...) state functions. But it also shows that these defences are insufficient to justify permanent sovereignty and that in many cases they actually count against it as a practice. They turn out to be compatible, furthermore, with the dispersal of resource rights away from the nation-state which global justice appears to demand. (shrink)

Perceptual dogmatism holds that if it perceptually seems to S that P, then S thereby has prima facie perceptual justification for P. But suppose Wishful Willy's desire for gold cognitively penetrates his perceptual experience and makes it seem to him that the yellow object is a gold nugget. Intuitively, his desire-penetrated seeming can't provide him with prima facie justification for thinking that the object is gold. If this intuitive response is correct, dogmatists have a problem. But if dogmatists have a (...) problem, you do too (well, most of you anyway). Reliabilists have denounced dogmatism's cognitive penetration problems, but they have problems with cognitive penetration that are even worse. (shrink)

Kant's views on revolution are notoriously paradoxical: on the one hand he appears to condemn all instances of revolution, but on the other he expresses enthusiasm for the French Revolution and other revolutionary acts. I argue that we can reconcile Kant’s views on revolution by examining instances when an individual is under a moral obligation to revolt. First, I show how Kant reconciles his position on the French Revolution with his position on revolution in general. His answer, however, raises additional (...) questions involving revolution in relation to his overall philosophical theory. Next, I present what is generally understood to be Kant’s philosophy on revolution, and Christine Korsgaard’s analysis using this traditional understanding to reconcile his seemingly contradictory views. After critiquing her position, I present my own analysis of Kant’s philosophy, and show how this apparent paradox can be resolved by examining an individual’s overriding moral obligation to leave the state of nature and establish civil society.

Perceptual dogmatism is a prominent theory in epistemology concerning the relationship between perceptual experience and reasonable belief. It holds that, in the absence of counterevidence, it is reasonable to believe what your perceptual experience tells you. Thus, if you are not aware of your experience’s casual history, then it doesn’t matter. Critics object that the causal history does matter: when a perceptual experience is caused in certain ways, it is unreasonable to trust what it tells you. These objections regularly appeal (...) to cognitive penetration and biased searches for evidence. Given the myriad accounts of what covert attention is, one wonders (at least I wondered) if biased patterns of covert attention could raise a new objection to dogmatism. I argue that, while covert selection might raise various problems for dogmatism, none of them are new. This is good news for dogmatism, because the fewer distinct problems it faces, the more likely it can resolve them all. (shrink)

One of the main challenges confronting Humean accounts of natural law is that Humean laws appear to be unable to play the explanatory role of laws in scientific practice. The worry is roughly that if the laws are just regularities in the particular matters of fact (as the Humean would have it), then they cannot also explain the particular matters of fact, on pain of circularity. Loewer (2012) has defended Humeanism, arguing that this worry only arises if we fail to (...) distinguish between scientific and metaphysical explanations. However, Lange (2013, 2018) has argued that scientific and metaphysical explanations are linked by a transitivity principle, which would undercut Loewer's defense and re-ignite the circularity worry for the Humean. I argue here that the Humean has antecedent reasons to doubt that there are any systematic connections between scientific and metaphysical explanations. The reason is that the Humean should think that scientific and metaphysical explanation have disparate aims, and therefore that neither form of explanation is beholden to the other in its pronouncements about what explains what. Consequently, the Humean has every reason to doubt that Lange's transitivity principle obtains. (shrink)

It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content?

If dangerous climate change is to be avoided, it is vital that carbon sinks such as tropical rainforests are protected. But protecting them has costs. These include opportunity costs: the potential economic benefits which those who currently control rainforests have to give up when they are protected. But who should bear those costs? Should countries which happen to have rainforests within their territories sacrifice their own economic development, because of our broader global interests in protecting key carbon sinks? This essay (...) develops an argument from the “principle of fairness,” which seeks to establish that outsiders should pay states with rainforests so as to share the costs of protection. If they do not, they can be condemned for free-riding on forest states. The argument is, I suggest, compelling and also capable of enjoying support from adherents of a wide variety of positions on global justice. (shrink)

In replying to certain objections to the existence of God, Robert Adams, Bruce Langtry, and Peter van Inwagen assume that God can appropriately choose a suboptimal world, a world less good than some other world God could have chosen. A number of philosophers, such as Michael Slote and Klaas Kraay, claim that these theistic replies are therefore committed to the claim that satisficing can be appropriate. Kraay argues that this commitment is a significant liability. I argue, however, that the relevant (...) defenses of theism are committed to the appropriateness of, not satisficing, but motivated submaximization. When one submaximizes with motivation, one aims at the optimum but accepts the good enough because of a countervailing consideration. When one satisfices, one aims at the good enough and chooses the good enough because it realizes her aim at the good enough. While commitment to the appropriateness of satisficing may be a significant liability, commitment to the appropriateness of motivated submaximization is not. (shrink)

Do numbers exist? Do properties? Do possible worlds? Do fictional characters? Many metaphysicians spend time and effort trying to answer these and other questions about the existence of various entities. These inquiries have recently encountered opposition: a group of philosophers, drawing inspiration from Aristotle, have argued that many or all of the existence questions debated by metaphysicians can be answered trivially, and so are not worth debating. Our task is to defend existence questions from the neo-Aristotelians' attacks.

There is a recent and growing trend in philosophy that involves deferring to the claims of certain disciplines outside of philosophy, such as mathematics, the natural sciences, and linguistics. According to this trend— deferentialism , as we will call it—certain disciplines outside of philosophy make claims that have a decisive bearing on philosophical disputes, where those claims are more epistemically justified than any philosophical considerations just because those claims are made by those disciplines. Deferentialists believe that certain longstanding philosophical problems (...) can be swiftly and decisively dispatched by appeal to disciplines other than philosophy. In this paper we will argue that such an attitude of uncritical deference to any non-philosophical discipline is badly misguided. With reference to the work of John Burgess and David Lewis, we consider deference to mathematics. We show that deference to mathematics is implausible and that main arguments for it fail. With reference to the work of Michael Blome-Tillmann, we consider deference to linguistics. We show that his arguments appealing to deference to linguistics are unsuccessful. We then show that naturalism does not entail deferentialism and that naturalistic considerations even motivate some anti-deferentialist views. Finally, we set out deferentialism’s failings and present our own anti-deferentialist approach to philosophical inquiry. (shrink)

In the Critique of Practical Reason, Kant grounds his postulate for the immortality of the soul on the presupposed practical necessity of the will’s endless progress toward complete conformity with the moral law. Given the important role that this postulate plays in Kant’s ethical and political philosophy, it is hard to understand why it has received relatively little attention. It is even more surprising considering the attention given to his other postulates of practical reason: the existence of God and freedom. (...) The project of this paper is to examine Kant’s postulate of the immortality of the soul, examine critiques of this argument, and show why the argument succeeds in showing that belief in the moral law also obligates one to believe in the soul’s immortality.

Some philosophers deny the existence of composite material objects. Other philosophers hold that whenever there are some things, they compose something. The purpose of this paper is to scrutinize an objection to these revisionary views: the objection that nihilism and universalism are both unacceptably uncharitable because each of them implies that a great deal of what we ordinarily believe is false. Our main business is to show how nihilism and universalism can be defended against the objection. A secondary point is (...) that universalism is harder to defend than nihilism. (shrink)

Kant’s deontological ethics, along with Aristotle’s virtue ethics and Mill’s utilitarian ethics, is often identified as one of the three primary moral options between which individuals can choose. Given the importance of Kant’s moral philosophy, it is surprising and disappointing how little has been written on his important contributions to moral education. Kant argues for a catechistic approach to moral education. By memorizing a series of moral questions and answers, an individual learns the basic principles of morality in the same (...) way that Martin Luther believed an individual should learn the tenets of Christianity. The difficulty, however, is that this approach appears to violate a central tenet of Kantian morality: virtuous acts must be performed out of respect for the moral law itself, not due to habituation. This paper demonstrates Kant’s significant contribution to moral education by showing how a catechistic moral education establishes the foundation necessary for autonomous action. (shrink)

We address the question of whether it is possible to operate a time machine by manipulating matter and energy so as to manufacture closed timelike curves. This question has received a great deal of attention in the physics literature, with attempts to prove no- go theorems based on classical general relativity and various hybrid theories serving as steps along the way towards quantum gravity. Despite the effort put into these no-go theorems, there is no widely accepted definition of a time (...) machine. We explain the conundrum that must be faced in providing a satisfactory definition and propose a resolution. Roughly, we require that all extensions of the time machine region contain closed timelike curves; the actions of the time machine operator are then sufficiently "potent" to guarantee that closed timelike curves appear. We then review no-go theorems based on classical general relativity, semi-classical quantum gravity, quantum field theory on curved spacetime, and Euclidean quantum gravity. Our verdict on the question of our title is that no result of sufficient generality to underwrite a confident "yes" has been proven. Our review of the no-go results does, however, highlight several foundational problems at the intersection of general relativity and quantum physics that lend substance to the search for an answer.

This introduction to the second international conference on Formal Ontology and Information Systems presents a brief history of ontology as a discipline spanning the boundaries of philosophy and information science. We sketch some of the reasons for the growth of ontology in the information science field, and offer a preliminary stocktaking of how the term ‘ontology’ is currently used. We conclude by suggesting some grounds for optimism as concerns the future collaboration between philosophical ontologists and information scientists.
