The Philosophy of Nature does not begin, as we expect, with nature. Instead, Hegel describes the practical and theoretical approaches we make to nature as philosophers; that is, in thought and, metaphorically, with our teeth. This ledge on the climb into nature is often overlooked as we rush from the logic into space and time. There may be two reasons for this. The first is a natural expectation that a philosophy of nature begin by describing natural phenomena, not our approaches (...) to them. The second is that the terms ‘practical’ and ‘theoretical’, familiar from the Logic and Philosophy of Spirit, may seem at first glance to be out of place here. Whatever the reason, these paragraphs have not been discussed at any length in the secondary literature. (shrink)

This book provides a compositional, truth-conditional, crosslinguistic semantics for evidentiality, the linguistic encoding of the source of information on which a statement is based. Central to the proposed theory is the distinction between what propositional content is at-issue and what content is not-at-issue. Evidentials contribute not-at-issue content, and can affect the level of commitment a sentence makes to the main proposition, contributed by sentential mood. In this volume, Sarah Murray builds on recent work in the formal semantics of evidentials (...) and related phenomena, and proposes a semantics that does not appeal to separate dimensions of illocutionary meaning. Instead, she argues that all sentences make three contributions: at-issue content, not-at-issue content, and an illocutionary relation. At-issue content is presented and made available for subsequent anaphora, but is not directly added to the common ground; not-at-issue content directly updates the common ground; and the illocutionary relation uses the at-issue content to impose structure on the common ground, which, depending on the clause type, can trigger further updates. 0The analysis is supported by extensive empirical data from Cheyenne, drawn from the author's own fieldwork, as well as from English and a variety of other languages.

Hegel’s discussion of sense certainty in the Phenomenology of Spirit contains the following, humorous, observation.

The essay distils from Badiou's writing a pedagogy based on his theories of knowledge and truth, as brought to bear on poetry and the arts. By following Badiou's implicit ontology of learning, which presupposes a dynamic and passionate engagement with a concrete situation, the essay argues that Badiou's view of modernity, in particular, contributes greatly to the educational topic, and offers an alternative teaching paradigm to the outmoded schools of criticism of the 20th century. It also argues that the concept (...) of universalism in education, as against identitarian particularism, is further evinced from a discussion of Badiou's study of St. Paul. (shrink)

Language and culture endow humans with access to conceptual information that far exceeds any which could be accessed by a non-human animal. Yet, it is possible that, even without language or specific experiences, non-human animals represent and infer some aspects of similarity relations between objects in the same way as humans. Here, we show that monkeys’ discrimination sensitivity when identifying images of animals is predicted by established measures of semantic similarity derived from human conceptual judgments. We used metrics from computer (...) vision and computational neuroscience to show that monkeys’ and humans’ performance cannot be explained by low-level visual similarity alone. The results demonstrate that at least some of the underlying structure of object representations in humans is shared with non-human primates, at an abstract level that extends beyond low-level visual similarity. Because the monkeys had no experience with the objects we tested, the results suggest that monkeys and humans share a primitive representation of object similarity that is independent of formal knowledge and cultural experience, and likely derived from common evolutionary constraints on object representation.

To examine Heidegger's pedagogy is to be invited into a particular era and cultural reality—starting in Weimar Germany and progressing into the rise and fall of the Third Reich. In his attempt to reform the German university in a strictly hierarchical, authoritarian and nationalistic mold, Heidegger addressed one group of students and professors and not another. The petit‐bourgeois student and the future philosophers he invited with his ‘logic of recruitment’ into the corps of instructors, would share his coded language with (...) its built‐in taboos and censorship. The result was a rhetoric of absolute self‐reference and a semiotic of pure propaganda, based on the evocation of the ancient Greeks in which the philosopher meant to project all that was properly Germanic. Heidegger's rhetoric is exclusionary; its politics and its philosophy are interpenetrating. His lecture courses grew increasingly poeticized, and thus mired in ambiguity, evasion, elision, avoidance, grandiloquence. Parallels are drawn in this essay between Heidegger and our time. Is Heidegger's insistence on autocratic controls within the German university comparable to the corporate positions taken today by some educators? How does the shifting relation between disciplines affect the role of the specialist? How might the sciences morales or humanities, along with the much maligned ‘humanism’, be redefined morally and holistically? (shrink)

Many languages grammatically mark evidentiality, i.e., the source of information. In assertions, evidentials indicate the source of information of the speaker while in questions they indicate the expected source of information of the addressee. This dissertation examines the semantics and pragmatics of evidentiality and illocutionary mood, set within formal theories of meaning and discourse. The empirical focus is the evidential system of Cheyenne (Algonquian: Montana), which is analyzed based on several years of fieldwork by the author.

The behavior of individuals currently living will generally have long-term consequences that affect the well-being of those who will come to live in the future. Intergenerational interdependencies of this nature raise difficult moral issues because only the current generation is in a position to decide on actions that will determine the nature of the world in which future generations will live. Although most are willing to attach some weight to the interests of future generations, many would argue that it is (...) not necessary to treat these interests as equivalent to those of the current generation. A common approach in this context is to use a system of discounting to evaluate future benefits and harms. This paper assesses the logic of discounting drawing on the writings of economists and philosophers. Much of the economic literature concerns the choice of an appropriate social discount rate. The social discount rate can be taken to reflect beliefs about the rights of future generations, a subject that has been extensively debated in the phioosophic literature. The writings of both economists and philosophers concerned with the weight to attach to the interests of future generations are reviewed and evaluated in this paper and the implications for environmental policy are discussed.

This paper discusses three potential varieties of update: updates to the common ground, structuring updates, and updates that introduce discourse referents. These different types of update are used to model different aspects of natural language phenomena. Not-at-issue information directly updates the common ground. The illocutionary mood of a sentence structures the context. Other updates introduce discourse referents of various types, including propositional discourse referents for at-issue information. Distinguishing these types of update allows a unified treatment of a broad range of (...) phenomena, including the grammatical evidentials found in Cheyenne (Algonquian) as well as English evidential parentheticals, appositives, and mood marking. An update semantics that can formalize all of these varieties of update is given, integrating the different kinds of semantic contributions into a single representation of meaning. (shrink)

Property rights are important institutions that influence economic performance and reflect the historical, cultural, and political realities of particular societies. Drawing on a variety of concepts from legal and economic studies, a framework for explaining the origin and evolution of property rights is developed and applied to the specific case of changing ground water rights in Nebraska. The Nebraska case is an interesting example of reliance on local control in regulating water use. Despite the importance of local initiatives in ground (...) water management, this case also illustrates the need for external support from the judicial and legislative systems. The evolution of ground water property rights in Nebraska, as in other parts of the United States, has been conditioned by historical circumstances and changing values and attitudes as well as by economic and political forces.

The Common Agricultural Policy (CAP) of the European Community (EC) has been criticized for causing a misallocation of resources, inequitable income transfers, and enormous budgetary costs. The purpose of this paper is to examine the political economy of agriculture and agricultural policy in the EC. The results of the analysis indicate that conflicts between national political objectives and broader, community-wide concerns are important factors in the performance of EC agriculture. The pressures for reform of the CAP will lead to modification (...) of the system, but changes in EC agricultural policy are likely to be moderate because of the inherent inertia of the policy-making process. As a result, the agricultural system in the EC will probably continue to evolve in an atmosphere of crisis with most reforms directed at symptoms rather than fundamental problems. (shrink)

Research focused on the prodromal period prior to the onset of psychosis is essential for the further development of strategies for early detection, early intervention, and disease pre-emption. Such efforts necessarily require the enrollment of individuals who are at risk of psychosis but have not yet developed a psychotic illness into research and treatment protocols. This work is becoming increasingly internationalized, which warrants special consideration of cultural differences in conceptualization of mental illness and international differences in health care practices and (...) rights regarding research participation. The process of identifying and requesting informed consent from individuals at elevated risk for psychosis requires thoughtful communication about illness risk and often involves the participation of family members. Empirical studies of risk reasoning and decisional capacity in young people and individuals with psychosis suggest that most individuals who are at-risk for psychosis can adequately provide informed consent; however ongoing improvements to tools and procedures are important to ensure that this work proceeds with maximal consideration of relevant ethical issues. This review provides a discussion of these issues in the context of international research efforts. (shrink)

The purpose of this paper is to review critically Julian Savulescu's principle of 'Procreative Beneficence,' which holds that prospective parents are morally obligated to select, of the possible children they could have, those with the greatest chance of leading the best life. According to this principle, prospective parents are obliged to use the technique of pre-implantation genetic diagnosis (PGD) to select for the 'best' embryos, a decision that ought to be made based on the presence or absence of both disease (...) traits and non-disease traits such as intelligence. While several articles have been written in response to Savulescu's principle, none has systematically explored its philosophical underpinnings to demonstrate where it breaks down. In this paper I argue that the examples that Savulescu employs to support his theory in fact fail to justify it. He presents these examples as analogous to PGD, when in fact they differ from it in subtle but morally relevant ways. Specifically, Savulescu fails to acknowledge the fact that his examples evoke deontological and virtue ethics concerns that are absent in the context of PGD. These differences turn out to be crucial, so that, in the end, the analogies bear little support for his theory. Finally, I lay out the implications of this analysis for reproductive ethics.

Across cultures, people employ space to construct representations of time. English exhibits two deictic space–time metaphors: the “moving ego” metaphor conceptualizes the ego as moving forward through time and the “moving time” metaphor conceptualizes time as moving forward towards the ego. Earlier research investigating the psychological reality of these metaphors has shown that engaging in certain types of spatial-motion thinking may influence how people reason about events in time. More recently, research has shown that people’s interactions with cultural artifacts may (...) also influence their representations of time. Extending research on space–time mappings in new directions, three experiments investigated the role of cultural artifacts, namely calendars and clocks, in the interpretation of metaphorical expressions about time. Taken together, the results provide initial evidence that, in their interpretation of ambiguous metaphorical expressions about time, people automatically access and use spatial representations of absolute time, whereby moving forward in space corresponds with moving later in time. Moreover, asking participants to use a reverse space–time mapping causes interference, which is reflected through their temporal reasoning. (shrink)

In this fascinating book, Sarah Worth addresses from a philosophical perspective the many ways in which reading benefits us morally, socially and cognitively.

Examined as an isolated situation, and through the lens of a rare and feared disease, Mr. Duncan's case seems ripe for second-guessing the physicians and nurses who cared for him. But viewed from the perspective of what we know about errors and team communication, his case is all too common. Nearly 440,000 patient deaths in the U.S. each year may be attributable to medical errors. Breakdowns in communication among health care teams contribute in the majority of these errors. The culture (...) of health care does not seem to foster functional, effective communication between and among professionals. Why? And more importantly, why do we not do something about it? (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Storytelling and Narrative Knowing:An Examination of the Epistemic Benefits of Well-Told StoriesSarah E. Worth (bio)IntroductionPeople love to tell stories. When something scary, or funny, or out of the ordinary happens, we cannot wait to tell others about it. If it was really funny, etc., we tell the story repeatedly, embellishing as we see fit, shortening or lengthening it as the circumstances prescribe. When people are bad storytellers we tend (...) not to pay as close attention to their stories; our minds drift, and we hope for a swift conclusion. We tend not to remember those stories as well as the ones that were carefully constructed and skillfully delivered. Storytelling is one of our primary forms of communication with other people. Narrativity is the principle way that human beings order their experience in time. It is also one of the primary ways that humans make coherent sense out of seemingly unrelated sequences of events. Thus, an account of how this ordering works is essential to understanding one of the many ways of knowing used by humans, one that has been widely unaccounted for, I believe. What I will argue in this article is that reading, telling, and hearing well-constructed narratives are not just idle pastimes that we have created for entertainment purposes or even as a mere means of communication. Rather, there are epistemological benefits to reading, hearing, and telling well-constructed narratives. In particular, by practicing what I call narrative reasoning, we develop this skill, just as by practicing discursive reasoning we develop discursive reasoning skills. In turn, we develop an enhanced reasoning ability that arises from narrative reasoning and narrative meaning construction. Ultimately, I will argue that those who are able to develop the capacity to reason narratively will be able to have a more comprehensive understanding of the human experience. [End Page 42]Defining NarrativeTo begin, I will go into some detail about what I mean when I talk about narratives since the reasoning skills that will ultimately come from engaging with narratives will be related to the way that we come to understand and make sense of them. Since I do not intend to posit a theory of narrative, I will talk about what constitutes narrativity and what sort of features contribute to increasing the narrativity of a story. To begin, narrative is generally the representation of an event or sequence of events. It is closely tied to description, but it goes beyond description. "My cat has fleas" is a description of a state of affairs. "My cat was bitten by a flea" is a narrative about my cat, which includes a description. Some theorists (such as Barthes and Rimmon-Kenan) argue that a narrative must consist of more than one event or state of affairs in order to be minimally considered a narrative. For my purposes, the change in states of affairs from one to another will be essential for understanding the cognitive aspects that can be gained from engaging with narrative. Although I do not advocate a minimal requirement for something to be considered a narrative, at least two, if not multiple, states of affairs increase narrativity significantly. Narratives also have a unified subject and some relatively easily understood temporal structure. Although many narratives do not order all of their events sequentially, good narratives will have a temporal order that can be gleaned by its reader.1An annal might be something that is temporally ordered and likely have more than two events or states of affairs, and for this reason it might be put into a category of "story form." The primary principle of organization of an annal, however, is merely a temporal list of events. It cannot count as a full-fledged narrative since it may be a temporal list of events that has no unified subject. For example,A: "The Space shuttle Challenger explodes in 1988, the Berlin wall comes down in 1989, there is a massacre at Srebenica, Bosnia in 1995."B: "The Space Shuttle Columbia blows up upon reentry to Earth; the Space Shuttle Challenger explodes upon take off."A is a temporally ordered list of events and is an annal; B, however, is...

Mastery imagery (i.e., images of being in control and coping in difficult situations) is used to regulate anxiety. The ability to image this content is associated with trait confidence and anxiety, but research examining mastery imagery ability's association with confidence and anxiety in response to a stressful event is scant. The present study examined whether trait mastery imagery ability mediated the relationship between confidence and anxiety, and the subsequent associations on performance in response to an acute psychological stress. Participants (N= (...) 130; 55% male;Mage= 19.94 years;SD= 1.07 years) completed assessments of mastery imagery ability and engaged in a standardized acute psychological stress task. Immediately prior to the task, confidence, cognitive and somatic anxiety intensity, and interpretation of anxiety symptoms regarding the task were assessed. Path analyses supported a model whereby mastery imagery ability mediated the relationship between confidence and cognitive and somatic anxiety interpretation. Greater mastery imagery ability and confidence were both directly associated with better performance on the stress task. Mastery imagery ability may help individuals experience more facilitative anxiety and perform better during stressful tasks. Improving mastery imagery ability by enhancing self-confidence may help individuals successfully cope with anxiety elicited during stressful situations. (shrink)

Bodily methodologies that engage with the affective, rhythmic, and temporal dimensions of movement have altered the landscape of social science and humanities research. Walking is one such methodology by which scholars have examined vital, sensory, material, and ephemeral intensities beyond the logics of representation. Extending this rich field, this article invokes the concept trans to reconceptualize walking research through theories that attend to the vitality and agency of matter, the interconnectedness between humans and non-humans, the importance of mediation and bodily (...) affect, and the necessity of acknowledging ethico-political responsibility. While theoretical and empirical research about embodied, emplaced, and sensorial relations between moving bodies and space are well developed in the field of walking studies, their entanglements become profoundly altered by theories of trans – transcorporeality, transspecies, and transmaterialities. Taking up trans theories we experiment in thinking-with a sonic art performance, Walking to the Laundromat, which probes bodily, affective, and gendered labour. (shrink)

Nuclear speckles are eukaryotic nuclear bodies enriched in splicing factors. Their exact purpose has been a matter of debate. The different proposed roles of nuclear speckles are reviewed and an additional layer of function is put forward, suggesting that by accumulating splicing factors within them, nuclear speckles can buffer the nucleoplasmic levels of splicing factors available for splicing and thereby modulate splicing rates. These findings build on the already established model that nuclear speckles function as a storage/recycling site for splicing (...) factors. Many studies have demonstrated proximity between nuclear speckles and sites of active transcription, suggesting that this juxtaposition can enhance the rates of gene expression. It is found that nuclear speckle disassembly increases splicing factor availability in the nucleoplasm, leading to an increase in splicing rates and faster release of nascent transcripts from the gene after transcription. Altogether, this era in which genomic and imaging approaches are applied to study nuclear organization has expanded the outlook on the possible roles of nuclear speckles. (shrink)

In her book Specifications Grading, Linda B. Nilson advocates for a grading regimen she claims will save faculty time, increase student motivation, and improve the quality and rigor of student work. If she is right, there is a strong case for many faculty to adopt some version of the system she recommends. In this paper, we argue that she is mostly right and recommend that faculty move away from traditional grading. We begin by rehearsing the central features of specifications grading (...) and providing two examples of how to implement it in philosophy classes. In light of the examples, we argue that specifications grading fulfills two of Nilson’s central desiderata but not the third. Since specifications grading generates two benefits that when combined increase student learning, without adding or increasing burdens, we conclude that student learning increases when courses are revised to include aspects of specifications grading.

ABSTRACTIn 1651, Alexander Ross published an attack on Thomas Browne's Pseudodoxia Epidemica, Bacon's Natural History and William Harvey's De generatione. Ross's work, Arcana Microcosmi, defended Aristotelian natural philosophy against the ‘new philosophy’ that figures like Bacon, Harvey and Browne represented. Though Ross's attacks on these authors make up no more than half of the treatise’s contents, the book’s paratextual materials emphasise scientific debate. While Ross's authorial approach advocates reading exclusively ancient authorities for the sake of glossing and transmitting their knowledge (...) to a wider public, in order to argue against the new philosophy Ross must engage with its textual production. Furthermore, his works advertise their focus on Bacon, Harvey and Browne, which would have attracted a readership drawn to new scientific approaches to knowledge formation. Ross's polemic represents an effort to model his devotion to ancient authority while also generating a reading public that would resist the new approach to reading that the new philosophy proposed.

On one view, the point of an assertion is to update the common ground (Stalnaker 1978, Karttunen 1974). On another, the point of an assertion is to propose an update to the com- mon ground (Groenendijk 2009, Mascarenhas 2009, and related work on the structure of discourse, e.g., Ginzburg 1996, Roberts 1996, Gunlogson 2001). In Murray (to appear), I merge these two views. I argue based on evidence from declarative sentences with eviden- tials that assertion has two components: what is (...) at-issue and what is not. The not-at-issue component of assertion is added directly to the common ground while the at-issue compo- nent is proposed to be added to the common ground. Here, I extend this analysis to yes/no questions in Cheyenne and their interaction with evidentials. I propose that the distinction between what is at-issue and what is not is also present in questions, and that it can be modeled in the same way. Specifically, both declarative and interrogative sentences make two contributions: they restrict and structure the common ground. The restriction is based on the not-at-issue component while the structuring relation is based on the at-issue component. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Peaceful Persuasion: The Geopolitics of Nonviolent RhetoricSarah E. DempseyPeaceful Persuasion: The Geopolitics of Nonviolent Rhetoric. Ellen W. Gorsevski. Albany: State University of New York Press, 2004.pp. 262. $55.00, hardcover.The overriding emphasis on violence, militarization, and retribution within current geopolitical contexts demands that we acquire greater understandings of nonviolent communicative practices. In Peaceful Persuasion, author Ellen Gorsevski, Professor of English and Communication at Oregon State University, argues that nonviolent (...) rhetoric tends to be ignored by scholars—that its methods, strategies, and impacts are often passed over and that nonviolence is often framed as hopelessly utopian, unrealistic, and ineffective. Gorsevski situates her study of nonviolent rhetoric less within its humanistic and religious inheritance, drawing instead on a contrast with existing models of rhetoric. As a strategy for rhetorical and political action, Gorsevski takes nonviolence to be instructive of new ways to reconfigure both rhetorical studies and social movement strategy.It is important to note that Gorsevski's need to study peaceful means of relating to others is driven as much by a love of rhetorical theory as by a passion for translating an understanding of nonviolent rhetoric into strategies for activists. As such, this book provides a solid introduction to rhetorical theory, including an appendix on the connection between rhetoric and nonviolence that details what activists have to gain from each. In addition, instructors will find useful a chapter on the specifics of incorporating nonviolence into speech communication classrooms.Peaceful Persuasion's greatest contribution to rhetorical studies is the careful drawing out of the many ways that a rhetorical take on nonviolence has become increasingly necessary. To make this solid case, Gorsevski draws on four very diverse case studies of nonviolent rhetoric. In a move that is both surprising and refreshing, Gorsevski's case studies do more than provide exemplars of how critics may read nonviolence as a powerful rhetorical strategy; each helps to further delineate the key characteristics of what has been, until now, a relatively undefined area of rhetorical action.Gorsevski's gift to her readers is the ability to demonstrate the rich subtleties of nonviolence through very different contexts. The case studies [End Page 89] draw from such different sources that at first seem disorienting. Upon reflection, it becomes clearer that they greatly complicate our notions of nonviolence, redressing the disservices of previous bleary analyses that configured nonviolence only by its lack of violence rather than according to its fruitful range of seemingly contradictory strategies. The cavernous distances each study crosses illuminate the multiplicity of forms, meanings, and strategies that nonviolence may take. As such, any definition of nonviolence that I may provide in this short review does a serious disservice to the depth that Gorsevski creates through her sometimes disjointed case studies.The case studies serve at least dual purposes, as each provides an analysis that extends our understandings of nonviolence in action as it also offers instructive mini-lessons for the further development of rhetorical studies. In the first case study, Gorsevski provides a contextualized analysis of critics' interpretations of the film The Spitfire Grill, which she shows to be reflective of the "predominantly accepting orientation that rhetoric and film critics hold for the idea that humans are characterized by "innate aggression" and violence" (68). For Gorsevski, this study demonstrates that nonviolence as a lens can be applied to a range of texts just as well as any other approach to rhetoric. Gorsevski moves her analysis of nonviolent rhetoric into the geopolitical realm for her study of President of Macedonia Kiro Gligorov's historic first speech before the United Nations. She takes his speech as evidence of the usefulness of pragmatic nonviolence, which entails "noncooperation or defiance of political adversaries in order to decry a perceived injustice" (72). Gligorov's speech illustrates that nonviolence and violence are best seen less as equivalent than, rather, as operating on a sliding scale. For Gorsevski, successful use of pragmatic nonviolence may even include a measure of violence as long as it serves to reduce the escalation of further strife.Next Gorsevski explores the visual rhetoric of the gendered body of Burmese activist and Nobel Peace Prize winner Aung San Suu Kyi to show...

In aging humans, aerobic exercise interventions have been found to be associated with more positive or less negative changes in frontal and temporal brain areas, such as the anterior cingulate cortex (ACC) and hippocampus, relative to no-exercise control conditions. However, individual measures such as gray-matter (GM) probability may afford less reliable and valid conclusions about maintenance or losses in structural brain integrity than a latent construct based on multiple indicators. Here, we established a latent factor of GM structural integrity based (...) on GM probability assessed by voxel-based morphometry, magnetization transfer saturation, and mean diffusivity. Based on this latent factor, we investigated changes in structural brain integrity during a six-month exercise intervention in brain regions previously reported in studies using volumetric approaches. Seventy-five healthy, previously sedentary older adults aged 63–76 years completed an at-home intervention study in either an exercise group (EG;n= 40) or in an active control group (ACG;n= 35). Measures of peak oxygen uptake (VO2peak) taken before and after the intervention revealed a time-by-group interaction, with positive average change in the EG and no reliable mean change in the ACG. Significant group differences in structural brain integrity changes were observed in the right and left ACC, right posterior cingulate cortex (PCC), and left juxtapositional lobule cortex (JLC). In all instances, average changes in the EG did not differ reliably from zero, whereas average changes in the ACG were negative, pointing to maintenance of structural brain integrity in the EG, and to losses in the ACG. Significant individual differences in change were observed for right ACC and left JLC. Following up on these differences, we found that exercising participants with greater fitness gains also showed more positive changes in structural integrity. We discuss the benefits and limitations of a latent-factor approach to changes in structural brain integrity, and conclude that aerobic fitness interventions are likely to contribute to brain maintenance in old age.

Parts and wholes come in an infinite variety, but in each instance something, namely relations, joins the parts together to make them into a whole rather than an Aristotelian "heap." The ontological status of relations is the subject of this dissertation. ;The question of whether relations are real presupposes some method of determining what is real. A modified version of Whitehead's ontological principle, or the idea that only real things can have effects on other things, serves as the test of (...) the reality. If any effects result from a whole but not from a collection of parts, then a whole differs from its parts and relations are real. Such effects can manifest themselves in two ways: parts themselves may somehow be affected by being joined into a whole or some new property may emerge with a whole that cannot be attributed to the parts taken separately. If one discovers either type of effect, then relations are real. ;The first section of the dissertation is an historical examination on the question of the reality of the relations. In the first chapter, the positions of Hume, Parmenides and Whitehead are considered but ultimately rejected. The second chapter examines the positions of Aristotle and Wittgenstein, thinkers for whom relations are in some cases real, while the third examines Plato's idea on relations. ;In the fourth chapter, a distinction between two types of relations is drawn. The difference between these relations is found in whether or not the parts joined are affected by being in a whole. Static relations are those which join parts into a whole without affecting those parts, while parts joined by dynamic relations are affected by being in a whole. Both static and dynamic wholes possess emergent properties which come into being only when parts are joined into wholes. ;The second section focuses on the consequences of the reality of relations in philosophy, specifically in ethics, logic and the philosophy of space and time.

There has been much discussion of changing agricultural structure in the United States. In this paper, the author reviews some of the factors contributing to structural change in the United States and describes the policies adopted by the European Community with respect to agricultural structure. The European experience with structural policies suggests that this approach is not very promising for the United States where no specific structural policies exist. The argument developed in this paper is that structural changes in agriculture (...) are simply one example of economic adjustment in a capitalist economy, that economic adjustments are generally desirable although they are not costless, and that discussions of agricultural structure should focus on methods to alleviate the costs of adjustment rather than on efforts to prevent change.

In this paper, I discuss the quantificational variability of Cheyenne indeterminates: the variety of interpretations they can receive and the grammatical contexts that condition these interpretations. Building on analyses of indeterminates in other languages, such as Kratzer and Shimoyama (2002), I present a Hamblin-style analysis of Cheyenne indeter- minates. The proposal builds on the analysis of declaratives and interrogatives argued for in Murray (2010). This analysis can account for the quantificational variability of indeterminates in the scope of propositional operators as (...) well as the scope of illocutionary mood markers. The analysis is formalized in an independently motivated update semantics (Update with Centering, Bittner 2011), which automatically provides the required alternatives. (shrink)

Chapter 1. The causal relata. Ordinary talk suggests that entities from different ontological categories can cause and be caused: Kathy's throw, the fact that Kathy threw, and Kathy herself can all cause the window to break. But according to the majority view, causation exclusively relates events. This chapter defends the contrary view that the causal relata are as miscellaneous as ordinary talk suggests. A question remains: is there an ontological kind K such that causal relations on entities of that kind (...) are somehow more fundamental than causal relations on the non-Ks? I argue that there is such a kind: facts. I defend this claim against objections. ;Chapter 2. Causation by omission. Ordinary talk also suggests that omissions can be causes. For example, if Barry promised to water Alice's plant, didn't water it, and the plant then dried up and died, then Barry's not watering the plant---his omitting to water the plant---is a cause of its death. But there are reasons to think that either there is no causation by omission, or there is far more of it than common sense allows. I argue that neither disjunct is acceptable, and propose that we avoid the dilemma by embracing the view that causation has a normative component. The proposal faces the objection that causation is a paradigmatic example of a natural, and so entirely non-normative, relation. I argue that the objection can be defused once we are clear about the kind of normativity that plays a role in causation by omission. ;Chapter 3. Causation and the Making/Allowing Distinction. Common sense morality suggests that it can matter morally whether an agent makes an outcome occur or merely allows it to occur. For example, it is far worse to pinch your little brother than to allow him to be pinched.
