Technologies and services provided to resource-poor farmers need to be relevant and compatible with the context in which they operate. This paper examines the contribution of extension services to the food security of resource-poor farmers in a rural village in South Africa. It considers these in terms of the local context and the production of African vegetables in household food plots. A mixture of participatory, qualitative and quantitative research tools, including a household survey, is used to argue that local production (...) practices contribute more to food security requirements than the extension services. This is because of the ability of African vegetables to grow relatively well in semi-arid areas where other exotic plants do not, their ability to provide at least two foodstuffs during their life cycle, and the ability of either the fruit or the leaves, or both, to be dried and stored for consumption in the winter months. These crops can make a significant contribution in terms of household food security, but a number of social and agroecological factors are constraining their production and placing their availability under threat. Despite this, the extension services remain focused on certain activities within vegetable garden projects, even when these are not meeting their proposed purpose—food security by means of cash-crop production. The paper concludes that social and agroecological constraints could be improved if the extension services were changed. This could include the use of context specific and low-cost technologies to ensure that these crops are able to increase their contribution to household food security for resource-poor farmers in semi-arid areas.

Whistleblowers have usually been treated as outcasts by private-sector employers. But legal, ethical, and practical considerations increasingly compel companies to encourage employees to disclose suspected illegal and/or unethical activities throughinternal communication channels. Internal disclosure policies/procedures (IDPP''s) have been recommended as one way to encourage such communication.This study examined the relationship between IDPP''s and employee whistleblowing among private-sector employers. Almost 300 human resources executives provided data concerning their organizations'' experiences.

Because of the growing debate concerning the nature of Soviet-type societies, a symposium-review was organized around two important recent books on the subject. The following are discussions of either one or both of the following volumes: Ferenc Feher, Agnes Heller, Gyorgy Markus, Dictatorship over Needs, St. Martin's Press (New York, 1983). Victor Zaslavsky, The Neo-Stalinist State: Class, Ethnicity and Consensus in Soviet Society, M.E. Sharpe, Inc. (New York, 1982). In social analysis, effective explanations alternate “thick description” with “thin description” Zaslavsky's (...) The Neo-Stalinist State and Feher's, Heller's and Markus’ Dictatorship over Needs, can be seen to track “actually existine socialism” down the respective paths of “thick” and “think” analysis.

The microbiome of human hair follicles (HFs) has emerged as an important player in different HF and skin pathologies, yet awaits in‐depth exploration. This raises questions regarding the tightly linked interactions between host environment, nutrient dependency of host‐associated microbes, microbial metabolism, microbe‐microbe interactions and host immunity. The use of simple model systems facilitates addressing generally important questions and testing overarching, therapeutically relevant principles that likely transcend obvious interspecies differences. Here, we evaluate the potential of the freshwater polyp Hydra, to dissect (...) fundamental principles of microbiome regulation by the host, that is the human HF. In particular, we focus on therapeutically targetable host‐microbiome interactions, such as nutrient dependency, microbial interactions and host defence. Offering a new lens into the study of HF – microbiota interactions, we argue that general principles of how Hydra manages its microbiota can inform the development of novel, microbiome‐targeting therapeutic interventions in human skin disease.

Zuidema et al. illustrate how empirical AGL studies can benefit from computational models and techniques. Computational models can help clarifying theories, and thus in delineating research questions, but also in facilitating experimental design, stimulus generation, and data analysis. The authors show, with a series of examples, how computational modeling can be integrated with empirical AGL approaches, and how model selection techniques can indicate the most likely model to explain experimental outcomes.

Philosophy has much to offer psychiatry, not least regarding ethical issues, but also issues regarding the mind, identity, values, and volition. This has become only more important as we have witnessed the growth and power of the pharmaceutical industry, accompanied by developments in the neurosciences. However, too few practising psychiatrists are familiar with the literature in this area. -/- The Oxford Handbook of Philosophy and Psychiatry offers the most comprehensive reference resource for this area ever published. It assembles challenging and (...) insightful contributions from key philosophers and others to the interactive fields of philosophy and psychiatry. Each contributions is original, stimulating, thorough, and clearly and engagingly written - with no potentially significant philosophical stone left unturned.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

In her ground-breaking and highly influential book Transformative Experience, L.A. Paul makes two claims: (1) one cannot evaluate and compare certain experiential outcomes (e.g. being a parent and being a non-parent) unless one can grasp what these outcomes are like; and (2) one can evaluate and compare certain intuitively horrible outcomes (e.g. being eaten alive by sharks) as bad and worse than certain other outcomes even if one cannot grasp what these intuitively horrible outcomes are like. We argue that the (...) conjunction of these two claims leads to an implausible discontinuity in the evaluability of outcomes. One implication of positing such a discontinuity is that evaluative comparisons of outcomes will not be proportionally sensitive to variation in the underlying features of these outcomes. This puts pressure on Paul to abandon either (1) or (2). But (1) is central to her view and (2) is very hard to deny. We call this the Shark Problem. (shrink)

While the challenges workers face in the gig economy are now well-known, reflections on emancipatory solutions in political philosophy are still underdeveloped. Some have pleaded for enhancing workers' bargaining power through unionisation; others for enhancing exit options in the labour market. Both strategies, however, come with unin-tended side-effects and do not exhaust the full potential for worker self-government present in the digital gig economy. Using the republican theory of freedom as non-domination , I argue that G.D.H. Cole's 20th-century defence of (...) guild socialism offers a promising avenue for enhancing worker autonomy in the gig economy. Platform companies rely on relational and structural domination to undermine worker autonomy, but Cole's guild socialism was specifically designed to enhance autonomy in the workplace. Following Cole's advice today would amount to a defence of worker-owned cooperative platforms. By putting workers in control of platform design and governance, cooperative platforms create new opportunities for worker autonomy. However, platform coopera-tivism faces serious challenges if it plans on becoming a realistic alternative to the traditional gig economy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Ambiguities of Mild Cognitive ImpairmentTim Thornton (bio)Keywordsclassification, disease, mild cognitive impairment, normative, valuesCorner and Bond's paper (2006) raises some key ethical questions about the classification and diagnosis of mild cognitive impairment (MCI). In this commentary, I wish to revise some of the general issues about the classification of mental disorder raised by this particular classificatory concept. The central issue raised is the connection between the pathologic status of (...) a condition and what I term the plain facts about the frequency and nature of its symptoms.There are a number of ethical questions raised by applying the label of MCI. Centrally, perhaps, is the concern, illustrated by the case vignettes, that a diagnosis carries negative repercussions that might outweigh the more narrowly medical advantages of an early diagnosis. But although that concern may be appropriate, such ethical complications are a danger of any psychiatric classification or diagnosis, even the most well grounded. Any psychiatric diagnosis can carry a danger of stigma, for example.What seems to make such ethical concerns more serious in this case—at least to a philosopher outsider—is the implicit further concern that MCI is not a real, objective, or, to use a more medical term, valid category or classification. If it is not valid, then any negative connotations of the diagnosis will not be outweighed by medical technological achievements. In other words, the further ethical issues are given much greater weight if the question of validity is not satisfactorily resolved.The question of the reality, objectivity, or validity of MCI can be divided into two issues:1. Is MCI a real, objective, or valid feature of psychological phenomenology?2. Is MCI a real, objective, or valid psychological illness, disease, or pathology?A condition might be a real, objective, or valid feature of psychological phenomenology without being a real illness. It might be some other aspect of human living. Szasz (1960) suggests that this is the case with mental illness (he might more properly say "so-called mental illness") as a whole. But, less controversially, the unusual ability to calculate, mentally and in a flash, the date of future Easter Sundays is a genuine feature of human living—some people possess the ability even if most do not—without either it, or its lack, being an illness. Being real as an illness is a very specific kind of being. It is this, I suggest, that raises difficulties in the case of MCI by contrast with the easier question of whether something is a genuine feature of human living in some other way. [End Page 21]From "normal" and "normative" to "correct" and "incorrect"Corner and Bond (2006) usefully suggest that the question of whether MCI is real is made more difficult by an ambiguity in the sense of the word normal. They suggest that although "physiologic and cognitive decline is assumed to be a normal experience" this still leaves "boundary problems" about "distinguishing normal aging from disease" (Corner and Bond 2006, 3–4). Thus, if the symptoms of MCI are continuous with the ordinary phenomena of physiologic and cognitive decline, then they might also be merely normal. But this does not settle the status of MCI because normal can mean either "normative, that is, usual; or it can mean nonpathologic" (Corner and Bond 2006, 4).On the assumption that MCI is at least continuous with phenomena that are normal, then its symptoms might be normal in the sense of usual but nevertheless pathologic: an inevitable illness. Or they might be usual and nonpathologic, that is, merely a feature of aging that, although regrettable, lacks the connotations of illness (e.g., the appropriateness, if not the possibility, of treatment). (In principle on the assumption in play—that the symptoms of MCI are normal—they might be unusual but nonpathologic akin, for example, to an improved ability to solve crosswords with age that might affect a small lucky proportion of the population. Perhaps such a crossword puzzler might be reassured by their doctor: "Well that is very unusual but there is no need to worry: it is not a symptom of any illness. You are perfectly normal.")Thus the question "Is MCI normal... (shrink)

This article explores how Mortimer J. Adler's philosophy of history, as it developed from the 1930s through the 1950s, affected the construction of Encyclopedia Britannica's Great Books of the Western World and the same set's Syntopicon. A thorough examination of Adler's influences (e.g. Arthur O. Lovejoy, Jacques Maritain, and Columbia University faculty) demonstrates that his philosophy of history derived from a coincidental confluence of developments in the fields of literature, history, and philosophy. Adler's processing of these trends reveals both irony (...) and paradox, and also explains some philosophical objections articulated by later foes of the great books idea. (shrink)

An influential view in the epistemology of testimony is that typical or paradigmatic beliefs formed through testimonial uptake are noninferential. Some epistemologists in particular defend a causal version of this view: that beliefs formed from testimony (BFT) are generated by noninferential processes. This view is implausible, however. It tends to be elaborated in terms that do not really bear it out – e.g. that BFT is fixed directly, immediately, unconsciously or automatically. Nor is causal noninferentialism regarding BFT plausibly expressed in (...) terms of belief-independent belief formation; the complex cognitive details of BFT fixation do not accord well with such a view. But perhaps the most significant issue is that the relevant causal notion of inference itself is not particularly well-defined, at least with respect to BFT. Causal noninferentialism in this domain is obscure as a result, but this does not in turn clearly vindicate any interesting version of inferentialism. (shrink)

In the early modern period one can find unity of consciousness arguments in the writings of Rene Descartes and G. W. Leibniz, and in the recent literature they have been defended by David Barnett, William Hasker, and Richard Swinburne (among others). Descartes's unity of consciousness argument for dualism is to be found in the sixth of his Meditations on First Philosophy. Descartes claims that his unity of consciousness argument was itself sufficient to establish substance dualism. Swinburne's central line of argument (...) involves deploying a number of puzzle cases. He argues that our intuitions about these cases can be accommodated only by adopting a “further fact” view of the self, according to which the continued existence of a person over time consists in the continued existence of a mental substance, and “it is metaphysically possible that the substance acquires a totally new body, totally new apparent memories, and character”.

In "The Disunity of Consciousness," Gerard O'Brien and Jon Opie argue that human consciousness is not synchronically unified. They suggest that the orthodox conception of the unity of consciousness admits of two readings, neither of which they find persuasive. According to them, "a conscious individual does not have a single consciousness, but several distinct phenomenal consciousnesses, at least one for each of the senses, running in parallel." They call this conception of consciousness the _multi-track account. I make three points in (...) reply: (1) O'Brien and Opie's characterization of the orthodox conception of the unity of consciousness is problematic; (2) their arguments in support of the multitrack account are unpersuasive; and (3) the phenomenon of intersensory integration suggests that O'Brien and Opie are wrong to claim that "the only sense in which it is correct to talk of a 'unified' consciousness (...) is that in which the representational contents of the various components coincide.".

In Knowledge and its Limits (2000) Williamson defends not only the negative claim that knowledge cannot be analysed, but also the positive claim that knowledge is the most general factive mental state. In this paper two objections to the positive claim are presented: First, knowledge is not more general than e. g. seeing. After discussing several alleged examples of seeing without knowing a new example is offered. Although both seeing and knowing are incompatible with luck, they are incompatible with different (...) kinds of luck. Secondly, factive mental states that are more general than knowledge are conceivable. Williamson's characterisation of knowledge as being the most general factive mental state is not substantial enough to pick out exactly one state. The idea that there is such a thing as a maximal factive mental state cannot be sustained merely on the assumption that knowledge is unanalysable. (shrink)

In this paper, I argue that businesses bear a pro tanto, negative, moral obligation to refuse to engage in economic relationships with representatives of intolerable ideologies. For example, restaurants should refuse to serve those displaying Nazi symbols. The crux of this argument is the claim that normal economic activity is not a morally neutral activity but rather an exercise of political power. When a business refuses to engage with someone because of their membership in some group, e.g., Black Americans, this (...) is a use of political power to signal that Black Americans are other. Conversely, when businesses engage with someone who is clearly representing an intolerable ideology, this is a use of political power that signals the acceptability of that ideology. Businesses should not do this. (shrink)

Since its discovery in 1959 the Aharonov-Bohm effect has continuously been the cause for controversial discussions of various topics in modern physics, e.g. the reality of gauge potentials, topological effects and nonlocalities. In the present paper we juxtapose the two rival interpretations of the Aharonov-Bohm effect. We show that the conception of nonlocality encountered in the Aharonov-Bohm effect is closely related to the nonseparability which is common in quantum mechanics albeit distinct from it due to its topological nature. We propose (...) a third alternative interpretation based on the loop space of holonomies which serves to solve some of the problems and we trace back the topological nonlocality and thereby the Aharonov-Bohm effect to their quantum mechanical origin. All three discussed interpretations are, of course, empirically equivalent. In fact, they present us with an instructive case study for the thesis of theory underdetermination by empirical data.

Place mouse over image continent. 2.1 (2012): 36–39. From an ethical and political perspective, people and property can hardly be separated. Indeed, the modern political subject – that is, the individual, the person, the self, the autonomous actor, the rational self-interest maximizer, etc. – has taken shape in and through the elaboration, institutionalization, and enactment of that which rightfully belongs to it. This thread can be traced back perhaps most directly to Locke’s notion that the origin of the political state (...) occurs when people rise above the state of nature by ceding the power to prosecute offenses. The rule of law begins then with a defense of the right to property. People become subjects by adhering to the social contract, which they do by deferring the defense of their own property to the state. In this light, the response of the United States federal government to the financial crisis of 2008 appears to many as a breach of the social contract. The chant “banks got bailed out, we got sold out” states the claim plainly. Why exactly did some subjects (e.g., the banks) have their property defended by the state (i.e., through the variety of programs including TARP, the discount window at the US Federal Reserve, etc.), when other subjects (e.g., homeowners) found themselves without protection of their property rights, forced to default on mortgage debts and face dispossession? Even if the rhetoric about “too big to fail” can be believed, and the collapse of the financial system would lead to negative consequences for people who had little or no connection to the activities that brought it about, such consequences need not call into question the notion that everyone stands equally before the law. To occupy, then, appears as a form of civil disobedience, an intentional, retaliatory breach of the social contract by those who feel that they have lost the support of the state to which they ceded their power as sovereign agents. The visible and the invisible The violation of property rights of people who have recognition, protection and power under the law destabilizes their very status as citizens and tests the limit of democracy. Does the financial system force the dematerialized victimization of individuals? Do people become numbers, or worse still, percentages of unemployed, tranches of defaulted mortgages and foreclosures? Are they perhaps instead disenfranchised prospectively from the privileged position occupied by virtual entities and actors such as those involved in the derivatives markets, always already exiled back into the physical, visible realm? The line of conflict appears to be drawn between invisibility/absence/deferral and visibility/presence/realization. The demonstrators occupy an excess property of those subjects, namely, the banks and financial elite, who did receive recognition and protection under the law. By domesticating this excess property, rendering its invisibility visible within the political economy, the protesters raise a new form of threat to the hegemonic order. To occupy, then, involves a rejection of the order under which the “99%” have been subjected to erasure. The occupation seeks creatively to establish a new means of communication and law for its subjects. In the face of an existing power structure that is increasingly disenfranchising the majority of people while consolidating nodes of power and influence, the “occupation”, or the work of the Occupy movement, involves seizing a space that refuses the rules of the existing, allegedly corrupt sovereign state. This refusal of governance extends even to include a steadfast refusal to articulate a strategy, to formulate a list of demands, to converse with the sovereign power on the grounds of its own conventions, to put forth a leader, to resolve the ambiguity of the movement into a discreet identity, face, or voice. Do these tactics provide a resolution to the problem that was its genesis? Not in such a direct and easily resolved manner, but it remains difficult to imagine a direct and simple resolution to the problematic of the breach of the social contract. The ambiguity of the situation has generated significant interest within the broader populace, though many people sympathetic to the cause appear to be frustrated because the movement has not simply put forward a short list of concrete demands, or even a set of leaders and spokespeople, much less a resolution. And yet, this lack of coherence appears as a resolution of a problem generic to protest movements in the past, where individual leaders can be removed or discredited, and lists of demands can be co-opted by others holding more political power. Meanwhile, the ambiguity has compelled imitations on a global scale, with the Occupy Wall Street participants consciously taking actions that can be replicated by anyone anywhere without significant cost. These actions have taken place not in a peripheral location such as a parking lot in New Jersey, but instead close to the centers of power and governance, adjacent to Wall Street, close to the White House, on college campuses, etc. This spontaneous archipelago of protests becomes an irritant, a negation of the accepted order of protests, but when the protesters themselves move outside of their encampments, they are escorted by the police, constantly monitored and maintained so that a permanent state of paranoid persecution takes hold. To occupy, occupying, occupation – these actions involve a variable degree of danger – are you willing to step into a different space, where the rule of law is unclear and evolving? Are you presenting yourself as a representative of the majority, the 99%? Who has a sense of belonging to the 99%? This previously invisible population becomes a focal point of political power, garners increasing public support, infects the public dialogue. The government recognizes this population by forcing it from the occupied space, removing the element of possession of property. It is at this point of conflict, in the struggle to hold the physical property, where the greatest friction and violence occurs. Scaling the rule of law While occupied, the property calls for a redress of grievances, a restoration of the rule of law. The Occupy movement does not select and put forward individuals or leaders, it puts forward places – the occupied property represents the point of conflict, not the individual. And it is this very property that the government then tries to reclaim. The movement remains faceless, anonymous, uncounted, or rather counted only as a mass, the self-labeled mass of 99%. These spaces are like refugee camps or favelas, but constructed to unite the political life and private life of the protesters. This objective is presented as a tactical necessity, as all other means of protest and communication have failed, leaving only the option of seizing, holding, occupying a property. But to what end, exactly? Can anyone deliberately return to the prior social contract, embrace, affirm, and govern in strict accordance with the earlier relationship to property, following the logic of Locke’s arguments? In this respect, the contemporary crisis indicates a new, transitional phase in the way that property operates, or rather, in the balance between real and virtual value. The roots of the crisis lay in the massive overvaluation of property caused by lax lending practices, as more people were encouraged to borrow more money, which drove up the prices of property. At the same time, these individual properties, these mortgages for homes actual families lived in and worked to support, were bundled into securities that could be bought, sold, and speculated on. The reduction of a physical house or piece of real estate to an almost incalculably small element in an investment vehicle appears as a scaling of the hedge that radically diminishes the value of any individually owned property. Moreover, a number of recently-innovated financial products allow investors to hedge in new ways, to deliberately spread risk around a portfolio in hopes of bringing returns even when the individual mortgage defaults. At the level of the ‘free’ market, these virtual negative valuations are designed to balance the physical positive valuation, though many of the biggest lenders are now being investigated for controlling both sides of this valuation, the positive and the negative, to facilitate both the creation and failure of the investments and to profit from both. The ability to benefit from both the negative and positive value of an investment is a result of a technologically enabled capacity to operate within a complex field. These layered and scaled investment vehicles and the simultaneous negation of their value together represent a commingling of the virtual and physical existence that is both complex and multiple. The valuation of a virtual property has tremendous power to change the valuation of the physical - either injecting it with or depriving it of funds, pumping in or draining life and energy. This situation has roots of its own – the notion of property advanced e.g., throughout the enclosure movement in Britain was, from the outset, an imposition of virtuality (i.e., the concept of law, the institutions associated with ownership, etc.) on the physical reality of land. 1 The difference today is that technological trading platforms combined with innovations within the financial services industry have enabled the reduction of each individual property receiving or losing value in scale to an almost atomic level. In turn, the number of properties held simultaneously and valued as a massive, multiple wholes – i.e., the derivatives market in mortgage-backed securities – is a new phenomenon made possible through the application of similar technologies and institutional structures. And those actors who can trade in these layers of complexity can then profit from the new phase of disassociation of the virtual and the physical – unconcerned with and operating at such a virtual distance from the individual residing physically on a particular piece of real estate that they no longer feel the tug of the physical tying them back to the physical, operating literally as in a video game, in a virtually distanced world. What can or should be done about this situation? Answers lie outside the scope of this current essay, but merit consideration in the near future… NOTE 1) Hernando de Soto has emphasized this dimension by empirically demonstrating its non-existence in many countries in The Mystery of Capital.

This course aims to assess the principle of compositionality (CP) and how it fits with recent developments in natural language interpretation, especially those that stress the role of context. We first try to lay down a suitable formal framework for CP, reviewing proposals by Montague, Janssen, Hendriks, Kracht and Hodges. Versions of CP of varying strength are formulated, and some recent results on the existence of compositional semantics and the (much debated) issue of the empirical import of CP discussed. Complementing (...) CP is the notion of context which, under modern (e.g. "dynamic") conceptions, not only conditions interpretation but also is transformed during interpretation. The tension between CP and context is examined relative to problems of anaphora, presupposition, idioms and ambiguity. A somewhat un-orthodox computational application of CP is suggested, emphasizing co-inductive aspects of interpretation that cut across the divide between model-theoretic and proof-theoretic approaches, and between procedural and declarative styles.

Both patients and clinicians frequently report problems around communicating and assessing pain. Patients express dissatisfaction with their doctors and doctors often find exchanges with chronic pain patients difficult and frustrating. This chapter thus asks how we could improve pain communication and thereby enhance outcomes for chronic pain patients. We argue that improving matters will require a better appreciation of the complex meaning of pain terms and of the variability and flexibility in how individuals think about pain. We start by examining (...) the various accounts of the meaning of pain terms that have been suggested within philosophy and suggest that, while each of the accounts captures something important about our use of pain terms, none is completely satisfactory. We propose that pain terms should be viewed as communicating complex meanings, which may change across different communicative contexts, and this in turn suggests that we should view our ordinary thought about pain as similarly complex. We then sketch what a view taking seriously this variability in meaning and thought might look like, which we call the “polyeidic” view. According to this view, individuals tacitly occupy divergent stances across a range of different dimensions of pain, with one agent, for instance, thinking of pain in a much more “bodycentric” kind of way, while another thinks of pain in a much more "mindcentric” way. The polyeidic view attempts to expand the multidimensionality recognised in, e.g., biopsychosocial models in two directions: first, it holds that the standard triumvirate— dividing sensory/cognitive/affective factors— needs to be enriched in order to capture important distinctions within the social and psychological dimensions. Second, the polyeidic view attempts to explain (at least in part) why modulation of experience by these social and psychological factors is possible in the first place. It does so by arguing that because the folk concept of pain is complex, different weightings of the different parts of the concept can modulate pain experience in a variety of ways. Finally, we argue that adopting a polyeidic approach to the meaning of pain would have a range of measurable clinical outcomes. (shrink)

Consider a simple form of process reliabilism: S is justified in believing that p if and only if S’s belief that p was formed through a reliable process. Such accounts are thought to face a counter-example in the form of defeaters. It seems possible that a belief might result from a reliable belief forming process and yet be unjustified because one possesses a defeater with respect to that belief. This counter-example is merely apparent. The problem of defeaters is just a (...) special case of the generality problem, i.e., the problem of determining which of the process types instantiated by a process token is relevant to determining that reliability of the process token. Drawing on similarities between cases that involve defeaters and cases that involve adverse local conditions, e.g., a white-out blizzard, I argue that any adequate solution to the generality problem for all cases that don’t involve defeaters will pick out an unreliable process type as relevant in cases that do involve defeaters. Thus, there is no sui generis problem of defeaters for simple process reliablism. (shrink)

R.G. Collingwood's An Essay on Metaphysics is a full-fledged response toA.J.Ayer's Language, Truth and Logic. Ayer's book forced Collingwood to revisit his critique of realism, to respond to the 'scientific dogmatism' of logical positivism, and to modify his own idealist metaphysical views in new and unprecedented ways. This article argues that Collingwood's critique of Ayer provides the impetus for the later metaphysical theory of An Essay on Metaphysics. Part I delineates Collingwood's critique of realism as a 'sea anemone view of (...) knowledge.' Part II argues that Ayer's logical positivism is a form of realism. Part III contends that Collingwood's response to Ayer -- a historical metaphysics based on absolute presuppositions and the logic of question and answer -- presupposes a novel, modified coherence theory of truth. Collingwood's later metaphysics signify merely a shift in how he responds to different forms of realism, however, rather than a significant turn in his thought. (shrink)

Few philosophers believe that G. E. Moore's notorious proof of an external world can give us justification to believe that skepticism about perceptual beliefs is false. The most prominent explanation of what is wrong with Moore's proof—as well as some structurally similar anti-skeptical arguments—centers on conservatism: roughly, the view that someone can acquire a justified belief that p on the basis of E only if he has p-independent justification to believe that all of the skeptical hypotheses that undermine the support (...) lent by E to p are false. In this paper I argue that conservatism does not make trouble for Moore's proof. I do this by setting up a dilemma concerning the notion of "justification to believe" that figures in conservatism. On one understanding of justification to believe, conservatism is subject to obvious counterexamples. On another understanding of justification to believe, conservatism is consistent with Moore's "proof conferring justification upon its conclusion. Since these two understandings exhaust the logical space, the conservative indictment of Mooreanism fails. (shrink)

The Cyrenaics assert that (1) particular pleasure is the highest good, and happiness is valued not for its own sake, but only for the sake of the particular pleasures that compose it; (2) we should not forego present pleasures for the sake of obtaining greater pleasure in the future. Their anti-eudaimonism and lack of future-concern do not follow from their hedonism. So why do they assert (1) and (2)? After reviewing and criticizing the proposals put forward by Annas, Irwin and (...) Tsouna, I offer two possible reconstructions. In the first reconstruction, I explain claim (1) as follows: happiness has no value above and beyond the value of the particular pleasures that compose it. Also, there is no "structure" to happiness. The Cyrenaics are targeting the thesis that happiness involves having the activities of one's life forming an organized whole, the value of which cannot be reduced to the value of the experiences within that life. I explain claim (2) as follows: a maximally pleasant life is valuable, but the best way to achieve it is to concentrate heedlessly on the present. In the second reconstruction, the good is radically relativized to one's present preferences. The Cyrenaics assert that we desire some particular pleasure, e.g., the pleasure that results from having this drink now. Thus, our telos -- which is based upon our desires -- is this particular pleasure, not (generic) 'pleasure' or the maximization of pleasure over our lifetime. As our desires change, so does our telos. I conclude that the scanty texts we have do not allow us to decide conclusively between these reconstructions, but I give some reasons to support the second over the first. (shrink)
