Linguistic phenomena of tense and aspect have been investigated in a great deal of theoretical work in linguistics, philosophy and computer science. Modern tense logics, established by Prior, are part of this effort. Point tense logics offer an intuitive representation of tense but lack the expressiveness to represent many aspectual structures. Interval tense logics offer more expressiveness but in the general case can be computationally intractable. From a linguistic perspective there is the problem of precisely how to formalise the aspectual (...) structures, such as a culmination and a culminated process. In this paper we define a computationally tractable augmented fragment of Halpern and Shoham's interval tense logic HS and apply it to represent a core set of aspectual structures, which are incorporated into a temporal semantics of a simple fragment of English. We model the logic fragment using timelines and define two procedures, one for constructing the minimal timelines that satisfy a formula and one for checking semantic entailments between one formula and another by comparing their timelines. The former is applied to compute models of temporal readings and the latter to check entailments between them. Possible extensions to the logic fragment and timeline models are discussed as ways of accounting for a wider range of linguistic behaviour. (shrink)

A Prolog implementation of a new theorem-prover for first-order classical logic is described. The prover is based on the calculus KE and the rules used for analysing quantifiers in free variable semantic tableaux. A formal specification of the rules used in the implementation is described, for which soundness and completeness is straightforwardly verified. The prover has been tested on the first 47 problems of the Pelletier set, and its performance compared with a state of the art semantic tableaux theorem-prover. It (...) has also been applied to model building in a prototype system for logical animation, a technique for symbolic execution which can be used for validation. The interest of these experiments is that they demonstrate the value of certain “characteristics” of the KE calculus, such as the significant space-saving in theorem-proving, the mutual inconsistency of open branches in KE trees, and the relation of the KE rules to “traditional” forms of reasoning.

Jennifer Hornsby has defended the Reasons-Knowledge Thesis : the claim that \-ing because p requires knowing that p, where the ‘because’ at issue is a rationalising ‘because’. She defends by appeal to the thought that it provides the best explanation of why the subject in a certain sort of Gettier case fails to be in a position to \ because p. Dustin Locke and, separately, Nick Hughes, present some modified barn-façade cases which seem to constitute counterexamples to and undermine Hornsby’s (...) way of motivating it by rendering their alternative Reasons-Explanation Thesis a better explanation of Hornsby’s datum. This paper defends and Hornsby’s argument for it against those objections. First, I point out that their supposedly intuitive verdict about the relevant barn-façade cases is not as intuitive as they think. Second, I point out that even if we share the intuition: we have strong reason to doubt the verdict anyway. And finally, I point out that since is independently implausible, the two problems can be tackled anyway. (shrink)

A startling look at one of this century's most influential philosophers, the book chronicles every stage of Foucault's personal and professional odyssey, from his early interest in dreams to his final preoccupation with sexuality and the nature of personal identity.

In the last decade there has been an upsurge in the popularity of electric mountain bikes. However, opinion is divided regarding the implications of this emerging technology. Critics warn of the dangers they pose to landscapes, habitats, and ecological diversity, whilst advocates highlight their potential in increasing the accessibility of the outdoors for riders who would otherwise be socially and/or physically excluded. Drawing on interview data with 30 electric mountain bike users in England, this paper represents one of the first (...) attempts to empirically explore the experiential, ecological and socio-cultural implications of this activity. Utilising Stiegler’s (2013a) account of the pharmakon, in which technology is positioned as both remedy and poison, we suggest that the e-mountain bike’s role in the promotion of social and environmental responsibility is both complex and contradictory. Specifically, findings indicate that while this assistive technology can play a key role in facilitating deeper connections between riders as well as an ethic of care towards others, it can, at the same time, generate more individualised and automated experiences of recreational mobility in outdoor environments.

An important function of the self is to identify external objects that are potentially personally relevant. We suggest that such objects may be identified through mere ownership. Extant research suggests that encoding information in a self-relevant context enhances memory , thus an experiment was designed to test the impact of ownership on memory performance. Participants either moved or observed the movement of picture cards into two baskets; one of which belonged to self and one which belonged to another participant. A (...) subsequent recognition test revealed that there was a significant memory advantage for objects that were owned by self. Acting on items had no impact on memory. Results are discussed with reference to the importance of self-object associations in cognition. (shrink)

In response to Hoeltje I concede the main point of his first section: for each logical truth S of the object language, it is a logical consequence of the Davidsonian theory of meaning I offered in my paper that S is logically true, contrary to what I asserted in the paper. However, I now argue that a Davidsonian theory of meaning may be formulated equally well in such a way that it not a logical consequence of the theory that S (...) is a logical truth. Nonetheless, the revised theory of meaning will still ‘entail’ in a wider sense that S is a logical truth, for we can prove by induction on the consequence class of the revised theory that S is a logical truth. So far, my disagreement with Hoeltje is over the more charitable interpretation of a passage from Davidson. I close by arguing that Davidson was mistaken on one point, a theory of meaning will entail a threefold distinction among the sentences of the object language, not a twofold distinction as he claimed.

Presenting portraits of many central figures in modern physics, including Stephen Hawking and Leonard Susskind, this critique of modern theoretical physics provides the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy.

Ethnic competition theory provides a powerful explanation for ethnic conflict, by demonstrating how variation in ethnic mobilization relates to intergroup struggles over scarce resources. However, the tendency to capture such relationships at the aggregate level, through macro-level proxies of intergroup competition, offers little insight into the processes through which ethnic grievances mobilize into contentious action. This article integrates insights from the social movements literature to address how competitive contexts crystallize into broader conflicts. Drawing on data from the civil rights-era Ku (...) Klux Klan—perhaps the quintessential case of contentious ethnic organization in the United States—the analysis focuses on the ways in which meso-level arrangements mediate the relationship between overarching competitive contexts and ethnic conflict. Results of a paired comparative analysis of KKK mobilization in Greensboro and Charlotte demonstrate that social and spatial relations within each city shaped the contours of perceived competition and subsequent ethnic organization in ways that were not always predictable through observation of conventional proxies of competition.

ABSTRACT: In memory of Professor Louise Marcil, from the University of Montreal, who died prematurely in April 1995, this special issue of Dialogue is dedicated to Equality. In addition to presenting the various contributions, the Introduction traces the main strands of Louise Marcil’s work on equality. The impressive corpus of her writings on the subject is characterized throughout by sensitivity to the historical and conceptual complexity of egalitarian theories and policies and by a depth of scholarship, the richness of which (...) defies classification into traditional philosophical schools. Moreover, far from being merely abstract scholarship, this work was clearly intended to strengthen actual egalitarian social projects, to which Louise Marcil was passionately committed. The contributions to this special issue of Dialogue have been selected in large part to reflect the diversity and scholarly standards of Louise Marcil’s approach to equality as well as its engaged spirit.

In this article, I argue for an historical understanding of the relationship between ideology and utopia/utopianism that positions the latter as a specifically modern compensation for the loss of the cosmologically grounded, unitary ideology supplied by the late medieval Christian Church. This claim relies upon but revises Fredric Jameson’s early theorization of the collaboration between ideology and utopia/utopianism, which emphasizes that utopian elements allow ideology to offer subjects a ‘compensatory exchange’ for their complicity. Developing my central argument requires considering the (...) current viability of the ‘secularization thesis’, which classically associated modernization with secularization but which has undergone heavy criticism and revision by social scientists over the past half-century. These theoretical discussions, finally, are couched within a critical appraisal of the status of utopianism in contemporary politics. (shrink)

This article argues for a task-based approach to identifying and individuating cognitive systems. The agent-based extended cognition approach faces a problem of cognitive bloat and has difficulty accommodating both sub-individual cognitive systems ("scaling down") and some supra-individual cognitive systems ("scaling up"). The standard distributed cognition approach can accommodate a wider variety of supra-individual systems but likewise has difficulties with sub-individual systems and faces the problem of cognitive bloat. We develop a task-based variant of distributed cognition designed to scale up and (...) down smoothly while providing a principled means of avoiding cognitive bloat. The advantages of the task-based approach are illustrated by means of two parallel case studies: re-representation in the human visual system and in a biomedical engineering laboratory. (shrink)

The spiritual rewards and intellectual challenges of Eastern philosophy are revealed in this visually stunning book, illustrated by Joe Lee and with 19th-century engravings. Eastern philosophy is not only an intellectual pursuit, but one that involves one’s entire being. Much of it is so deeply entwined with the non-intellectual art of meditation, that the two are impossible to separate. In this survey of the major philosophies of India, China, Tibet and Japan, Jim Powell draws upon his knowledge of Sanskrit and (...) Chinese, as well as decades of meditation. Whether tackling Buddha, Confucius, Lao Tzu, Dogen, the Dalai Lama or Patanjal–Powell’s insights are deeply illuminating. All the major philosophies of India, China, Tibet and Japan are explained and everyone, from beginner to expert, will find Eastern Philosophy For Beginners an insightful overview. (shrink)

Using Jim Woodward's Counterfactual Dependency account as an example, I argue that causal claims about indeterministic systems cannot be satisfactorily analysed as including counterfactual conditionals among their truth conditions because the counterfactuals such accounts must appeal to need not have truth values. Where this happens, counterfactual analyses transform true causal claims into expressions which are not true.

Modern physics describes the mechanics of the Universe. We have discovered a new foundation for physics, which explains the components of the Universe with precision and depth. We quantify the existence of Aether, subatomic particles, and the force laws. Some aspects of the theory derive from the Standard Model, but much is unique. A key discovery from this new foundation is a mathematically correct Unified Force Theory. Other fundamental discoveries follow, including the origin of the fine structure constant and subatomic (...) particle g-factors, a slight correction of neutron magnetic moment, a geometrical structure for charge, the quantification of electromagnetic charge as separate from electrostatic charge, a more precise meaning of spin, the quantification of space-resonance in five dimensions, and a new system of quantum units. The Aether quantifies as a fabric of quantum rotating magnetic fields with electromagnetic, electrostatic, and gravitational dipole structures. Subatomic particles quantify as angular momentum encapsulated in a quantum, rotating magnetic field. All quantum, atomic, and molecular processes can be precisely modeled, leading to discrete physics with new understandings and insights. (shrink)

l examine the degree to which the so-called “deep ecology” movement embodies a feminist sensibility. In part one I take a brief look at the ambivalent attitude of “eco-feminism” toward deep ecology. In part two I show that this ambivalence sterns largely from the fact that deep ecology assimilates feminist insights to a basically masculine ethical orientation. In part three I discuss some of the ways in which deepecology theory might change if it adopted a fundamentally feminist ethical orientation.

This highly original book calls for, and suggests, a new way of considering war and warfare.

When we start with the wrong question, no matter how good an answer we get, it won’t give us the results we want. Rather than joining the throngs who are asking, When will this economic crisis be over? Jim Wallis says the right question to ask is How will this crisis change us? The worst thing we can do now, Wallis tells us, is to go back to normal. Normal is what got us into this situation. We need a new (...) normal, and this economic crisis is an invitation to discover what that means. Some of the principles Wallis unpacks for our new normal are . . . • Spending money we don’t have for things we don’t need is a bad foundation for an economy or a family. • It’s time to stop keeping up with the Joneses and start making sure the Joneses are okay. • The values of commercials and billboards are not the things we want to teach our children. • Care for the poor is not just a moral duty but is critical for the common good. • A healthy society is a balanced society in which markets, the government, and our communities all play a role. • The operating principle of God’s economy says that there is enough if we share it. • And much, much more . . . In the pages of this book, Wallis provides us with a moral compass for this new economy—one that will guide us on Wall Street, Main Street, and Your Street. Embracing a New Economy Getting back to "the way things were" is not an option. It is time we take our economic uncertainty and use it to find some moral clarity. Too often we have been ruled by the maxims that greed is good, it’s all about me, and I want it now. Those can be challenged only with some of our oldest and best values—enough is enough, we are in it together, and thinking not just for tomorrow but for future generations. Jim Wallis shows that the solution to our problems will be found only as individuals, families, friends, churches, mosques, synagogues, and entire communities wrestle with the question of values together.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.3 (2001) 207-224 [Access article in PDF] Virtual Witnessing and the Role of the Reader in a New Natural Philosophy Richard Cunningham [Figures]How did the self-described new natural philosophies of the early modern period displace other philosophic (moral, ethical, legal), and specifically religious, discourses as the locus of truth in our culture? Natural philosophy's rejection of disputation and of revelation as means of producing truth (...) in favor of the "discovery" of truth was more accurately an introduction of the invention of truth than of its discovery, and this invention demanded the creation of and participation of a certain kind of reader. Rhetorical examination of the early modern magnetic philosopher William Gilbert's most influential work, De Magnete, 1 will help us understand the "paradigm change," to use Thomas Kuhn's oft-misquoted term, 2 from a culture that accepted probabilistic truth in the natural realm to one that expected moral certainty, from a culture that accepted revelation as a legitimate means of access to truth to one that increasingly recognized only the "discovery" of truth through sensual experience disciplined through experiment.One way this paradigm change was effected was through the inclusion of the reader as an active participant in the new natural philosophies. The reader was included in the new natural philosophies by engendering in him desires for particular forms of knowledge and particular ways of attaining that knowledge. Peter Dear notes that "in the seventeenth century old practices changed and new ones appeared. Those changing practices represent shifts in the meaning of experience itself" (12-13), and he then asks the question that might well have been on the tongues of many as the old practices gave way to the new: "how can a universal knowledge-claim about the natural world be justified on the basis of singular items of individual experience?" (13). A crucially important way to justify the universal knowledge-claim on singular items of individual experience [End Page 207] was through the employment of a technique Steven Shapin and Simon Schaffer have labeled "virtual witnessing" (60-65). Briefly, "virtual witnessing" describes the use of linguistic resources to produce a vicarious experience enabling a reader to confer agreement as though she had actually been present when an experiment was conducted. Virtual witnessing alone, however, cannot explain how the scientific became the dominant truth-producing paradigm in our culture. Virtual witnessing intermingled with a variety of other elements in early modern natural philosophy to encourage readers to participate in the invention of "true" accounts of the world in which we live. In this article I will apply the tools of rhetorical analysis as I use the example of De Magnete to elaborate on how a Foucauldian form of disciplinary impulse combined in the early modern period with the technology of virtual witnessing to create an audience inculcated with desire, interest, and belief in the new natural philosophy, which had to precede and accompany expansion of the scientific into the dominant truth-producing paradigm it has long since become.For the sake of clarity I should expound upon the two key elements of my argument, "discipline," in the Foucauldian sense in which I use the term, and "virtual witnessing." According to Michel Foucault, "discipline" is "a political anatomy of detail... situated on the axis that links the singular and the multiple" (139-49), and I argue that this point, on the "axis that links the singular and the multiple," is exactly the point that enables modern science. William Gilbert's De Magnete can help us understand how knowledge and power--or epistemê and technê, to use another, perhaps more rhetorically inflected, vocabulary--combined in the early modern period to produce the effects that would become those of modern science. Gilbert provides an excellent example of the movement from the production of truth through revelation to the production of truth through discovery and the experimental method. De Magnete persuades its reader by rendering visible a formerly invisible "universal nature," 3 so that truth is no longer warranted by the invisible workings... (shrink)

Standard philosophical discussions of theory-ladeness assume that observational evidence consists of perceptual outputs (or reports of such outputs) that are sentential or propositional in structure. Theory-ladeness is conceptualized as having to do with logical or semantical relationships between such outputs or reports and background theories held by observers. Using the recent debate between Fodor and Churchland as a point of departure, we propose an alternative picture in which much of what serves as evidence in science is not perceptual outputs or (...) reports of such outputs and is not sentential in structure.

After Ontotheology: Reciprocal, Caring, Creative, and Right Relationships With the end of ontotheology we may realize, as Dewey did, that what sustains us is our caring relationships with physical nature, biological life, and other persons. My paper argues that relationships are ontologically basic and caring relations are morally basic. Right relationship binds us to the world and holds us together. We live by the grace of others. I conclude that after ontotheology, we must seek to form reciprocal, caring, and creative (...) relationships. (shrink)

Art and its Objects by Richard Wollheim had a major impact on aesthetics and the philosophy of art when it was first published in 1968. Of the arguments offered in response to Wollheim’s essay, Jerrold Levinson’s intentional-historical theory of art has been one of the most enduring. Levinson was influenced by three key sections of Wollheim’s enquiry: Section 40, which considers the claim that works of art fall under a concept of art, or that we are disposed to regard certain (...) things as works of art; and Sections 60 and 61, which deal with art as a historical phenomenon, and problems arising from its identification and interpretation. To date, these claims have been raised as points of contention in the philosophy of art. This paper takes a different perspective. Wollheim’s understanding of art’s historicity draws explicitly on the literature of theoretical art history. Via Wollheim, old art-historical problems will reappear as new philosophical questions.

The purpose of this article is to examine three different approaches to autonomy in order to demonstrate how each leads to a different conclusion about the ethicality of advertising. I contend that Noggle's belief-based autonomy theory provides the most complete understanding of autonomy. Read in conjunction with Arendt's theory of cooperative power, Noggle's theory leads to the conclusion that advertising does not violate consumers' autonomy. Although it is possible for advertisers to abuse the power granted them by society these abuses (...) do not constitute a violation of consumers' autonomy. (shrink)

Some biological processes move from step to step in a way that cannot be completely understood solely in terms of causes and correlations. This paper develops a notion of mechanistic information that can be used to explain the continuities of such processes. We compare them to processes that do not involve information. We compare our conception of mechanistic information to some familiar notions including Crick’s idea of genetic information, Shannon-Weaver information, and Millikan’s biosemantic information.

Deep ecologists have criticized reform environmentalists for not being sufficiently radical in their attempts to curb human exploitation of the nonhuman world. Ecofeminists, however, maintain that deep ecologists, too, are not sufficiently radical, for they have neglected the cmcial role played by patriarchalism in shaping the cultural categories responsible for Western humanity’s domination of Nature. According to eco-feminists, only by replacing those categories-including atomism, hierarchalism, dualism, and androcentrism - can humanity learn to dweIl in harmony with nonhuman beings. After reviewing (...) the eco-feminist critique both of reform environmentalism and of deep ecology, I sketch a critical dialogue between eco-feminism and deep ecology. (shrink)

This paper presents a counterfactual account of what a mechanism is. Mechanisms consist of parts, the behavior of which conforms to generalizations that are invariant under interventions, and which are modular in the sense that it is possible in principle to change the behavior of one part independently of the others. Each of these features can be captured by the truth of certain counterfactuals.

A central mistake in Rolf Gruner's recent article on understanding in the socia sciences in ferreted out, and consideration of it is used both to analyse Gruner's interpretation of understanding and to sketch a more adequate interpretation. The mistake is in distinguishing meanings and facts. The analysis suggests that Gruner was forced to see understanding both as a special kind of explanation and at the same time as no explanation. The sketch offers a distinction of three senses of ?understanding? ? (...) as identification of a certain kind of subject matter, as explanation of it, and as a subjective feeling consequent upon such explanation. (shrink)

Recent developments in ethics and postmodemist epistemology have set the stage for a reconceptualization of environmental ethics. In this paper, I sketch a path for postmodemism which makes use of certain notions current in contemporary environmentalism. At the center of my thought is the idea of place: place as the context of our lives and the setting in which ethical deliberation takes place; and the epistemological function of place in the construction of our understandings of self, community, and world. Central (...) to these themes, in tum, are the related notions of myth, narrative, storied residence, and ethical vernacular. (shrink)

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a critique by (...) Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (shrink)
