I argue that a version of Pascal's Wager applies to the persistent vegetative state with sufficient force that it ought to part of advance directives.

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people perceive patients in a persistent vegetative state to have less mentality than the dead. Following on from Gomes and Parrott, we provide evidence to show that participants' responses in the initial experiments are an artifact of the questions posed. Results from two experiments show that, once the questions have been clarified, people do not ascribe more mental capacity to the (...) dead than to PVS patients. There is no reason to think that people perceive PVS patients as more dead than dead. (shrink)

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people judge patients in a persistent vegetative state to have less mental capacity than the dead. They explain this result by claiming that people have implicit dualist or afterlife beliefs. This essay critically evaluates their experimental findings and their proposed explanation. We argue first that the experiments do not support the conclusion that people intuitively think PVS patients have less mentality (...) than the dead. And second, we provide an alternative explanation of our ascriptions of mentality to the dead and PVS patients, one which turns on Epicurean considerations about the nature of death. (shrink)

Recent work in neuroimaging suggests that some patients diagnosed as being in the persistent vegetative state are actually conscious. In this paper, we critically examine this new evidence. We argue that though it remains open to alternative interpretations, it strongly suggests the presence of consciousness in some patients. However, we argue that its ethical significance is less than many people seem to think. There are several different kinds of consciousness, and though all kinds of consciousness have some (...) ethical significance, different kinds underwrite different kinds of moral value. Demonstrating that patients have phenomenal consciousness — conscious states with some kind of qualitative feel to them — shows that they are moral patients, whose welfare must be taken into consideration. But only if they are subjects of a sophisticated kind of access consciousness — where access consciousness entails global availability of information to cognitive systems — are they persons, in the technical sense of the word employed by philosophers. In this sense, being a person is having the full moral status of ordinary human beings. We call for further research which might settle whether patients who manifest signs of consciousness possess the sophisticated kind of access consciousness required for personhood. (shrink)

Consciousness in experimental subjects is typically inferred from reports and other forms of voluntary behaviour. A wealth of everyday experience confirms that healthy subjects do not ordinarily behave in these ways unless they are conscious. Investigation of consciousness in vegetative state patients has been based on the search for neural evidence that such broad functional capacities are preserved in some vegetative state patients. We call this the standard approach. To date, the results of the standard approach (...) have suggested that some vegetative state patients might indeed be conscious, although they fall short of being demonstrative. The fact that some vegetative state patients show evidence of consciousness according to the standard approach is remarkable, for the standard approach to consciousness is rather conservative, and leaves open the pressing question of how to ascertain whether patients who fail such tests are conscious or not. We argue for a cluster-based ‘natural kind’ methodology that is adequate to that task, both as a replacement for the approach that currently informs research into the presence or absence of consciousness in vegetative state patients and as a methodology for the science of consciousness more generally.

In debates over life and death it is often said that one should err on the side of caution—that is, on the side of life. In light of the recent case of Terri Schiavo, it is explained how the “err-on-the-side-of-life” argument proceeds, and an objection to it is offered.

Is the being in an irreversible persistent vegetative state as the result of a horrible accident numerically identical to the human person, Lindsay, who existed before the accident? Many proponents of Thomistic metaphysics have argued that Aquinas’s answer to this question must be “yes.” In particular, it seems that Aquinas’s commitment to both Aristotelian hylomorphism and the unity of substantial form (viz., that each body/soul composite possesses one and only one substantial form) entails the position that the (...) human person remains alive as long as biological life persists. I argue, however, that although Aquinas does possess a deeply integrated account of human nature and is indeed committed to the claim that the person, Lindsay, exists as long as Lindsay’s body lives, there is good reason to suppose that he also holds that the body in the PVS is not Lindsay’s body in anything more than an equivocal sense.

This paper aims to propose and justify a framework for understanding the concept of personhood in both biological and artificial entities. The framework is based on a set of requirements that make up a suitable cognitive architecture for an entity to be considered a person, including the ability to have propositionally structured intentional states, having a form of sensory capabilities, and having a means of interacting with the environment. The case of individuals in a persistent vegetative state, (...) as studied by Owen, serves as an example to show the importance of each of these requirements and the possibility of a "hybridization" of personhood. The proposed set of requirements provide a complete framework for understanding the concept of personhood and highlight the significance of cognitive architecture in determining personhood. (shrink)

The aim of the present article is to accomplish two things. The first is to show that given some further plausible assumptions, existing challenges to the indispensability of knowledge in causal explanation of action fail. The second is to elaborate an overlooked and distinct argument in favor of the causal efficacy of knowledge. In short, even if knowledge were dispensable in causal explanation of action, it is still indispensable in causal explanation of other mental attitudes and, in particular, some reactive (...) attitudes and factive emotions. Taking into account this sort of causal efficacy in determining which mental states are genuine mental states opens up new perspectives for defending the view that knowledge is the most general factive and genuine mental state.

The paper presents an ethnographic approach to the study of culture change, here the culture of the practice of Afiye (Caste system) among the Yala communities of Cross River State and why the persistence of such culture by a homogenous community such as the Yala community? The paper further, wonders why after the high status achieved by the Yala people in every facet of life and indeed the influence of factors of change, such as Christianity, globalization, technology and modernity, (...) that the Afiye practice still remained unchanged. It is the discovery of this paper that the factors responsible for the persistence of this practice against all factors of change are anchored on the religious factor, cultural identity, socio-political factors and, economic factors. It is the argument of this paper that instead of the factors above contributing to its persistence, it should be the ready factors to its discontinuity. For the advantages outweigh any given disadvantages. It is therefore the conclusion of this paper that the persistence of this practice be used to abrogate the practice which will in turn leads to an egalitarian Yala society, built on trust, unity and a mutual acceptance of one another, as a people, who indeed appreciate and love themselves as exemplified in their greetings.

How to reconcile monadic simplicity with the successive plurality of the monadic states ? The doctrine of continued creation seems to entail the existence of independent temporal parts and thus lead to the thesis that the world contains only transitory things. I try to show how Leibniz has the resources to get out of this quandary. The analysis of the concept of extension shows that a plurality of states does not constitute a divisible aggregate. Then I examine the Leibnizian interpretation (...) of continued creation, by com- paring it to the scholastic and Cartesian Background. From thence I conclude that Leibniz’s final thesis is that monads are wholly present at each moment of their duration. (shrink)

Many philosophers hypothesize that our concept of personal identity is partly constituted by the one-person-one-place rule, which states that a person can only be in one place at a time. This hypothesis has been assumed by the most influential contemporary work on personal identity. In this paper, we report a series of studies testing whether the hypothesis is true. In these studies, people consistently judged that the same person existed in two different places at the same time. This result undermines (...) some widely held philosophical assumptions, supports others, and fits well with recent discoveries on identity judgments about inanimate objects and non-human animals.

This study used a flame atomic absorption spectrometer (FAAS) and atomic fluorescence spec-trophotometer (AFS) to detect the concentrations of chromium (Cr), cadmium (Cd), lead (Pb), hy-drargyrum (Hg) and arsenic (As) in soils and three genotypes of vegetables in greenhouse, as well as analyzed the physical and chemical properties of soils, including soil pH, soil organic matter (OM), basic nutrients, electrical conductivity (EC) and cation exchange capacity (CEC) in Guan- zhong areas, Shaanxi province, China. The results showed that comparing to subsoil, (...) the sampled topsoil is enriched in Cr, Cd, Pb, As and Hg. Cd (0.83 - 3.17 mg·kg-1) and Hg (0.40 - 1.44 mg·kg-1) are exceeding the limited value stated in “the 2006 Greenhouse Vegetable Producing Environmental Quality Evaluation Standards” of 0.40 mg·kg-1 and 0.35 mg·kg-1 respectively. However, Nanzhuang greenhouse soil is within the limits. The heavy metal pollution index (HPI) of soil in Sanyuan (8.10) is the highest and in Dongzhang (4.23) is the lowest. The contents of Pb (0.201 - 0.376 mg·kg-1) were exceeding the limited value (0.20 mg·kg-1) in vegetables species, and Cd (0.0363 - 0.0572 mg·kg-1) in some place were also exceeding the limited value (0.05 mg·kg-1). Greenhouse soils were becoming acidified year after year; the ratios of N, P and K in soil were seriously imbalanced. According to the impacting factors, OM, pH, available P, EC and CEC have obviously effected the accumulation of Cr and Hg. However, there was not enough evidence for the effects of available nitrogen and available potassium. (shrink)

Status of the national currency of Ukraine exchange rate has been characterized as unstable in recent years. Herewith, the Government has not implemented decisive measures on its stabilization, as a rule, underestimating the importance of the Hryvnia exchange rate stability for the successful economic growth in terms of socio-economic transformations. It should also be noted that in modern conditions among scientific and methodical approaches to the State exchange rate formation mechanisms some uncertainty regarding basic and additional tools for such (...) regulatory activities allocation is still persist. The problem relevance is exacerbated by the lack of effective policy (coordination between the NBU and the Government actions) regarding the national currency stabilization as an indispensable prerequisite for an effective macroeconomic development. These circumstances determine the importance of factors influencing the national currency exchange rate and its regulation tools research, as well as new organizational and economic mechanisms for the national currency exchange rate in Ukraine stabilization identification. In the emerging market economy conditions formation of the efficient State currency exchange-rate regulation system provides an opportunity not only to stabilize its exchange rate in different socio-economic conditions, but to create the basis for improvement the country economic development as a whole. Given this, the issue of effective tools for the national currency exchange-rate regulation by the state determination is of theoretical, practical and methodological significance. This emphasizes the relevance of further scientific-methodological and practical principles in-depth development for the national currency exchange-rate regulation. (shrink)

The article discusses the corruption of the state administration and clergy as one of the factors of persistence of paganism in Later Roman Empire. The spread of the practice of bribing state officials and clergymen by pagans, coming from different social strata of the Late Roman Society is demonstrated by various examples. It is suggested that this phenomenon was a result of the spread of suffragium.

al-Fārābi was well aware that ecumenism can easily convert to tyranny if a certain city–state attempts to impose its laws outside its territory. State legislation depends on specific cultural and historical factors which deprives it from being universal because culture and history could not unite different nations in an ecumenical state. Legislation has to be built on universal premises, e.g. on philosophy, so as to serve the needs of a global state. Philosophy is the bond which (...) unites humans and communities, while religion and legislation are disruptive factors. Despite the fact that in our days there are different philosophies, philosophy encourages dialogue, not hatred. As a result, al-Fārābi was right when he founded his ecumenical state on philosophy. Consequently, philosophers ought to persuade the citizens through rational arguments, dialectic, symbols and religion so as to accept the existence of an ecumenical state. The goal of this state is the supreme good, understood as the theoretical living. Al-Fārābi’s ecumenism is a means for the perfection of human beings and societies and not simply for the augmentation of wealth, as it is seen today. Al-Fārābi dreams of an anthropocentric ecumenical state. I support that this should be the form of modern ecumenism. While modern scholars have strong objections to the governing of philosophers, we should agree that philosophy is the appropriate universal language. The persistence on power and other divisive factors, such as religion or tradition, is doomed to fail. (shrink)

The tension between the authority of states and the authority of international institutions is a persistent feature of international relations. Legitimacy assessments of international institutions play a crucial role in resolving such tensions. If an international institution exercises legitimate authority, it creates binding obligations for states. According to Raz’s well-known service conception, legitimate authority depends on the reasons for actions of those who are subject to it. Yet what are the practical reasons that should guide the actions of states? (...) Can states be bound by international institutions on all kinds of issues or are certain issues exempted because of sovereignty considerations? This paper argues that self-regarding reasons cannot ground political authority with the respective demand for compliance. Since reasons for states concern individuals both inside and outside of their jurisdiction and other state peoples, self-regarding reasons for states, which form a domain of personal pursuits or sovereign decisions, are highly restricted.

This paper situates the Sub-Saharan African state amidst the conflictual interface between the forces of political and economic globalization that have been ushered in the state milieu by neo-liberalism . The paper argues that states are situated in an imperialistic globalization with capitalistic economic extirpation as central concern and social justice as a peripheral one. This categorically explicates the persistence of globalised economies and localized oppressive state apparatuses, ideologies and practices. The paper also contends that the forces (...) of economic globalization have superimposed the cultural mantra in the Sub-Saharan Africa state milieu, rendering it virtually impossible to pursue a Rights Based Approach to Development (RBAD). The apparent assault by this globalization from above (economic globalization), continues almost unabated due to absence of an afro centric globalization from below to mitigate the homogenizing effects of economic globalization. Worse still, the inability of political globalization to check the daunting implications of economic globalization using a human rights antidote and the consequent slumber of the glocalisation dialectic in the African state locale explicate the problematic of Africa in the wake of erosion from above (global pillage) and devolution from below.

Disorders of consciousness (DoC)—that is, unresponsive wakefulness syndrome/vegetative state and minimally conscious state—are debilitating conditions for which no reliable markers of consciousness recovery have yet been identified. Evidence points to the GABAergic system being altered in DoC, making it a potential target as such a marker.

Consciousness and emotion feature prominently in our personal lives, yet remain enigmatic. Recent advances prompt further distinctions that should provide more experimental traction: we argue that emotion consists of an emotion state (functional aspects, including emo- tional response) as well as feelings (the conscious experience of the emotion), and that consciousness consists of level (e.g. coma, vegetative state and wake- fulness) and content (what it is we are conscious of). Not only is consciousness important to aspects of (...) emotion but structures that are important for emotion, such as brainstem nuclei and midline cortices, overlap with structures that regulate the level of consciousness. The intersection of consciousness and emotion is ripe for experimental investigation, and we outline possible examples for future studies. (shrink)

In 1959 two French neurologists, Pierre Mollaret and Maurice Goullon, coined the term coma dépassé to designate a state beyond coma. In this state, patients are not only permanently unconscious; they lack the endogenous drive to breathe, as well as brainstem reflexes, indicating that most of their brain has ceased to function. Although legally recognized in many countries as a criterion for death, brain death has not been universally accepted by bioethicists, by the medical community, or by the (...) public. I this paper, I defend brain death as a biological concept. I challenge two assumptions in the brain death literature that have shaped the debate and have stood in the way of an argument for brain death as biological. First, I challenge the dualism established in the debate between the body and the brain. Second, I contest the emphasis on consciousness, which prevents the inclusion of psychological phenomena into a biological criterion of death. I propose that the term organism should apply both to the functioning of the body and the brain. I argue that the cessation of the organism as a whole should take into account three elements of integrated function. Those three elements are: 1) the loss of integrated bodily function; 2) the loss of psychophysical integration required for processing of external stimuli and those required for behavior; and, 3) the loss of integrated psychological function, such as memory, learning, attention, and so forth. The loss of those three elements of integrated function is death. (shrink)

It seems obvious that phenomenally conscious experience is something of great value, and that this value maps onto a range of important ethical issues. For example, claims about the value of life for those in a permanent vegetative state, debates about treatment and study of disorders of consciousness, controversies about end-of-life care for those with advanced dementia, and arguments about the moral status of embryos, fetuses, and non-human animals arguably turn on the moral significance of various facts about (...) consciousness. However, though work has been done on the moral significance of elements of consciousness, such as pain and pleasure, little explicit attention has been devoted to the ethical significance of consciousness. In this book Joshua Shepherd presents a systematic account of the value present within conscious experience. This account emphasizes not only the nature of consciousness, but the importance of items within experience such as affect, valence, and the complex overall shape of particular valuable experiences. Shepherd also relates this account to difficult cases involving non-humans and those with disorders of consciousness, arguing that the value of consciousness influences and partially explains the degree of moral status a being possesses, without fully determining it. The upshot is a deeper understanding of both the moral importance of phenomenal consciousness and its relations to moral status. This book will be of great interest to philosophers and students of ethics, bioethics, philosophy of psychology, philosophy of mind and cognitive science. (shrink)

We generally accept that medicine’s conceptual and ethical foundations are grounded in recognition of personhood. With patients in vegetative state, however, we’ve understood that the ethical implications of phenomenal consciousness are distinct from those of personhood. This suggests a need to reconsider medicine’s foundations. What is the role for recognition of consciousness (rather than personhood) in grounding the moral value of medicine and the specific demands of clinical ethics? I suggest that, according to holism, the moral value of (...) medicine is secured when conscious states are recognized in everyday medical science. Moreover, consciousness fully motivates traditional principles of clinical ethics if we understand respect for autonomy as respect for the dominion of an experiencer in the private, inescapable realm of bodily experience. When medicine’s foundations are grounded in recognition of consciousness, we understand how patients fully command respect even when they lack capacity to exercise their bodily dominion through decision-making.

Disorders of consciousness include coma, the vegetative state and the minimally conscious state. Such patients are often regarded as unconscious. This has consequences for end of life decisions for these patients: it is much easier to justify withdrawing life support for unconscious than conscious patients. Recent brain imaging research has however suggested that some patients may in fact be conscious.

Mental images, or envisioning things with your "mind's eye," are now studied via multiple levels of observation and involve computational neuroscience, robotics and many disciplines that complement philosophy and form integral parts of cognitive science. MENTAL IMAGERY AND CREATIVITY offers an historical analysis of the use of "mental images" in science. This book also gives many useful illustrations, depicting roles of imagery with 21st century technology, including the usage of imagery, fMRIs and internet connections, allowing people to control virtual avatars (...) or robots at remote distances. Imagery formations and brain imaging techniques allow non-communicative patients, who appear to be in vegetative states, to communicate effectively, despite brain damage. Notwithstanding many 21st century developments of imagery combined with technology and science, many speculative accounts of imagery arose in the 20th century. Philosophic developments, regarding the relation between mental imagery and creativity, are provided in order to compare and contrast speculative and rational foundations. Creativity is defined in relation to problem-solving, inventiveness, art, discovery and cognitive formations of ranges of possibilities, arising before and after realizations (i.e., when one recognizes real and unreal events or solutions), involving images of events, solutions and alternatives.

Should the state punish its disadvantaged citizens who have committed crimes? Duff has recently argued that where disadvantage persists the state loses its authority to hold individuals to account and to punish for criminal wrongdoings. I here scrutinize Duff’s argument for the claim that social justice is a precondition for the legitimacy of state punishment. I sharpen an objection to Duff’s argument: with his framework, we seem unable to block the implausible conclusion that where disadvantage persists the (...) state lacks the authority to punish any citizen for any crime. I then set out an alternative line of argument in support of the claim that social deprivation can threaten the states legitimate punitive authority. I argue that a penal system must incorporate certain proportionality principles, and that these principles cannot both be met where citizens suffer from deprivation. (shrink)

I consider the current best interests of patients who were once thought to be either completely unaware (to be in PVS) or only minimally aware (MCS), but who, because of advanced fMRI studies, we now suspect have much more “going on” inside their minds, despite no ability to communicate with the world. My goal in this chapter is twofold: (1) to set out and defend a framework that I think should always guide thinking about the best interests of highly cognitively (...) compromised patients, and then (2) to defend a particular conclusion that applies to this specific patient population. The framework requires us to ask two questions: Is the individual suffering? Is the individual gaining any benefit from life? There must be benefit of some sort for life to be worth preserving, and the benefit must outweigh any suffering (if there is suffering present). I then argue it would be best overall to allow these patients to die. Either these patients are not really very aware at all, in which case they are most likely not suffering, but not benefiting from life either, or they are mentally intact enough to make benefit a theoretical possibility, but in fact they are not benefiting because they cannot communicate with anyone. Such patients would most likely suffer. As there is no way currently to address their suffering, we should allow them to die. No matter the truth about their cognitive lives, death would either be a neutral event, or a blessing. (shrink)

We discuss at some length evidence from the cognitive science suggesting that the representations of objects based on spatiotemporal information and featural information retrieved bottomup from a visual scene precede representations of objects that include conceptual information. We argue that a distinction can be drawn between representations with conceptual and nonconceptual content. The distinction is based on perceptual mechanisms that retrieve information in conceptually unmediated ways. The representational contents of the states induced by these mechanisms that are available to a (...) type of awareness called phenomenal awareness constitute the phenomenal content of experience. The phenomenal content of perception contains the existence of objects as separate things that persist in time and time, spatiotemporal information, and information regarding relative spatial relations, motion, surface properties, shape, size, orientation, color, and their functional properties.

Persistent disagreements may induce parties in the disagreement to experience a strong state of anxiety. Such anxiety has a psychological nature in ordinary cases of disagreement (i.e., cases which do not impact on the doxastic identity of the opposing epistemic agents). On the contrary, the more the content of a disagreement concerns basic issues related to the non-negotiable views for the parties involved, the more anxiety turns out to be of an epistemic kind, and, accordingly, suggests a set (...) of normative consequences. I will outline the main differences between ordinary and doxastic-identity-related disagreements in terms of the nature of the anxiety they give rise. In light of this distinction, I will characterize religious disagreements as disagreements of the latter type, and I will provide a few insights for approaching them. (shrink)

Philosophers often state that the persistence of objects in vision is experienced differently than the persistence of sounds in audition. This difference is expressed by using metaphors from the metaphysical endurantism/perdurantism debate. For instance, it is claimed that only sounds are perceived as “temporally extended”. The paper investigates whether it is justified to characterize visually experienced objects and auditorily experienced sounds as different types of entities: endurants and perdurants respectively. This issue is analyzed from the perspective of major specifications (...) of the endurance/perdurance distinction connected, inter alia, with the notions of temporal parts and temporal localization. It is argued that it is unjustified to characterize visually experienced objects and auditorily experienced sounds as different types of entities in respect of how they persist. On the other hand, the apparent difference in the way of persisting can be explained by the presence of contingent differences between typical visual and auditory experiences. (shrink)

According to a persistent objection against metaethical expressivism, this view is committed to a strong version of internalism which is unable to account for cases where a person’s moral judgment and motivation come apart. Recently, leading expressivists have argued that they can meet this objection by maintaining that moral judgments consist in non-cognitive states that motivate in normal conditions. In this paper, it is maintained that an important dimension of internalism has, on the whole, gone unnoticed: Internalist claims vary (...) depending on whether moral judgments and motivation are understood as dispositional states or occurrent states. This variation can be invoked in an argument showing that expressivists are indeed committed to versions of internalism that make it impossible to account for cases in which moral judgment and motivation diverge.

Nonreductive physicalism states that actions have sufficient physical causes and distinct mental causes. Nonreductive physicalism has recently faced the exclusion problem, according to which the single sufficient physical cause excludes the mental causes from causal efficacy. Autonomists respond by stating that while mental-to-physical causation fails, mental-to-mental causation persists. Several recent philosophers establish this autonomy result via similar models of causation :1031–1049, 2016; Zhong, J Philos 111:341–360, 2014). In this paper I argue that both of these autonomist models fail on account (...) of the problem of Edwards’s Dictum. However, I appeal to foundational principles of action theory to resuscitate mental-to-mental causation in a manner that is consistent with the models of causation endorsed by these autonomists.

Confronting persistent and widening inequality in educational opportunity, advocates have regarded the right to education as a linchpin for reform. In the forty years since the Supreme Court relegated that right to the domain of state constitutional law, its power has surged and faded in litigation challenging state school finance systems. Like so many of the students it is meant to protect, however, the right to education has generally underachieved, in part because those wielding it have not (...) always appreciated its distinctive forms and function. Deconstructed, the right to education held by children has been formulated doctrinally as both a claim-right, imposing affirmative duties on the state to act, and an immunity, disabling certain state action. These two strands—oft-manifested as the claim-right to educational “adequacy” and an immunity entailing “equality” of educational opportunity—once considered irreconcilable, are actually interlocked by the right’s core historical function to protect children’s liberty and equality interests. And yet the right to education is ill equipped to fulfill its protection function. Education clauses in state constitutions do not fix the standards for mutually enforcing equality and adequacy. This encumbers already-reluctant courts in addressing educational disparities and emboldens legislative resistance when they do. Appreciating that the right to education has a protection function entailing equality and liberty interests nevertheless suggests that the right can be adjudicated in a way that unifies the demands and guarantees of substantive due process and equal protection. That union holds the potential to ameliorate the enforcement standards thereby reconstituting the right to education as a mainstay of reform. (shrink)

Background: A bean is the seed of one of several genera of the flowering plant family Fabaceae, which are used as vegetables for human or animal food. They can be cooked in many different ways, including boiling, frying, and baking, and are used in many traditional dishes throughout the world. Beans are one of the longest-cultivated plants. Broad beans, also called fava beans, in their wild state the size of a small fingernail, were gathered in Afghanistan and the Himalayan (...) foothills. In a form improved from naturally occurring types, Beans were an important source of protein throughout old and new world history, and still are today. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment. Methods: In this paper, the design of the proposed Expert System was produced to help farmers and those interested in agriculture in diagnosing many of the Bean diseases such as Fusarium wilt, Charcoal rot or ashy stem blight, Bacterial leaf spot and blight, Mung bean yellow mosaic virus, Cercospora leaf spot. The proposed expert system presents an overview of Bean diseases are given, the cause of diseases outlined and the treatment of disease whenever possible is given out. CLIPS Expert System language was used for designing and implementing the proposed expert system. Results: The proposed Bean diseases diagnosis expert system was evaluated by Agricultural experts and some friends interested in agriculture and they were satisfied with its performance. Conclusions: The proposed expert system is very useful for Farmers and those interested in agriculture. (shrink)

According to perdurantism, objects persist by being spread out over time, just as composite three-dimensional objects are spread out over space. Just as a composite three-dimensional object is spread out over space by having spatial parts, objects persist, according to perdurantism, by having temporal parts. Perdurantism can be stated more precisely by saying what exactly a temporal part is. In the sequel, Theodore Sider's definition of "instantaneous temporal part" shall be assumed: x is an instantaneous temporal part of y at (...) instant t =df. x exists at, but only at, t; x is part of y at t; and x overlaps at t everything that is part of y at t. Much more could be and has been said about how perdurantism should be formulated. Though interesting in their own right, nothing of importance here turns on these matters of formulation. (shrink)

Should we understand implicit attitudes on the model of belief? I argue that implicit attitudes are (probably) members of a different psychological kind altogether, because they seem to be insensitive to the logical form of an agent’s thoughts and perceptions. A state is sensitive to logical form only if it is sensitive to the logical constituents of the content of other states (e.g., operators like negation and conditional). I explain sensitivity to logical form and argue that it is a (...) necessary condition for belief. I appeal to two areas of research that seem to show that implicit attitudes fail spectacularly to satisfy this condition—although persistent gaps in the empirical literature leave matters inconclusive. I sketch an alternative account, according to which implicit attitudes are sensitive merely to spatiotemporal relations in thought and perception, i.e., the spatial and temporal orders in which people think, see, or hear things.

David Lewis is a natural target for those who believe that findings in quantum physics threaten the tenability of traditional metaphysical reductionism. Such philosophers point to allegedly holistic entities they take both to be the subjects of some claims of quantum mechanics and to be incompatible with Lewisian metaphysics. According to one popular argument, the non-separability argument from quantum entanglement, any realist interpretation of quantum theory is straightforwardly inconsistent with the reductive conviction that the complete physical state of the (...) world supervenes on the intrinsic properties of and spatio-temporal relations between its point-sized constituents. Here I defend Lewis's metaphysical doctrine, and traditional reductionism more generally, against this alleged threat from quantum holism. After presenting the non-separability argument from entanglement, I show that Bohmian mechanics, an interpretation of quantum mechanics explicitly recognized as a realist one by proponents of the non-separability argument, plausibly rejects a key premise of that argument. Another holistic worry for Humeanism persists, however, the trouble being the apparently holistic character of the Bohmian pilot wave. I present a Humean strategy for addressing the holistic threat from the pilot wave by drawing on resources from the Humean best system account of laws. (shrink)

The central and defining characteristic of thoughts is that they have objects. The object of a thought is what the thought concerns, or what it is about. Since there cannot be thoughts which are not about anything, or which do not concern anything, there cannot be thoughts without objects. Mental states or events or processes which have objects in this sense are traditionally called ‘intentional,’ and ‘intentionality’ is for this reason the general term for this defining characteristic of thought. Under (...) the heading of ‘thought’ we can include many different kinds of mental apprehension of an object—including relatively temporary episodes of contemplating or scrutinising, as well as persisting states like beliefs and hopes which are not similarly episodic in character. These are all ways of thinking about an object. But even construing ‘thought’ in this broad way, it is clear that not all mental states and events are thoughts: sensations, emotions and perceptual experiences are not thoughts, but they are also paradigmatically mental. Do these mental states and events have objects too? Or are there mental states and events which have no objects? (shrink)

The performance of natural behavior is commonly used as a criterion in the determination of animal welfare. This is still true, despite many authors having demonstrated that it is not a necessary component of welfare – some natural behaviors may decrease welfare, while some unnatural behaviors increase it. Here I analyze why this idea persists, and what effects it may have. I argue that the disagreement underlying this debate on natural behavior is not one about which conditions affect welfare, but (...) a deeper conceptual disagreement about what the state of welfare actually consists of. Those advocating natural behavior typically take a “teleological” view of welfare, in which naturalness is fundamental to welfare, while opponents to the criterion usually take a “subjective” welfare concept, in which welfare consists of the subjective experience of life by the animal. I argue that as natural functioning is neither necessary nor sufficient for understanding welfare, we should move away from the natural behavior criterion to an alternative such as behavioral preferences or enjoyment. This will have effects in the way we understand and measure welfare, and particularly in how we provide for the welfare of animals in a captive setting. (shrink)

In many African states, numerous different pre-colonial systems of power – such as kingships, sultanates or chieftaincies – which have a traditional legitimacy often confirmed in colonial and post-colonial times, have survived till our day. Their role in the contemporary republican state has been studied by many African intellectuals, and the views of Kwame Anthony Appiah, a thinker originating from Ghana, are of particular interest. He believes that in order to understand the significance of traditional authority and the phenomenon (...) of its continued existence in contemporary Africa, it is important to consider the source of its legitimacy. Appiah presents various sources – symbolic, religious and state – from which local African rulers derive the right to exert power and to exact obedience from their subjects. He minimizes the significance of most of these, however, and concludes that the basic source of legitimacy for traditional authority in the contemporary African state is the fact that this power, being a very important point of reference for the group over which it is wielded, reinforces its members’ sense of self-respect, and helps form their identity. He uses this idea to attempt to reconcile the continued existence of African power systems with liberal theory. Appiah, who is very unfavorably disposed towards most political and social hierarchies, views the political rights of individuals as the rights of citizens, not as the rights of persons who are the depositaries of some attributed or hereditary status. He enumerates the costs, in terms of liberal principles, of allowing traditional monarchy to persist. In his view, it is contrary to the liberal principle of public offices being open to persons of merit for the king of the Ashanti to be chosen from among persons of royal lineage. Such a perspective should generate a generally negative attitude towards the monarchy of the Ashanti, a people from whom Appiah originates, and yet he views Ashanti’s traditional monarchy as a source of pride.

Hydranencephaly is a developmental malady, where the cerebral hemispheres of the brain are reduced partly or entirely too membranous sacs filled with cerebrospinal fluid. Infants with this malady are presumed to have reduced life expectancy with a survival of weeks to few years and which solely depends on care and fostering of these individuals. During their life span these individuals demonstrate behaviours that are termed “vegetative” by neuroscientists but can be comparable to the state of being “aware” or (...) “conscious”. Based on the most simplified definition for consciousness i.e. “awareness” or “to be aware”, these individuals are undeniably aware of their existence and therefore should be termed “conscious”. The bigoted approach of neuroscience towards understanding consciousness is usually linked with the cortex of the brain and therefore a malady as hydranencephaly poses a great challenge to this field. This paper is a compilation of behaviours and aptitudes observed in several cases of hydranencephaly which suggests, that consciousness is not just a brain process, but is a highly quantum computed process that follows laws of quantum physics, giving rise to the subjective experience of consciousness in these individuals.

It is usual to distinguish between two kinds of doxastic attitude: standing or dispositional states, which govern our actions and persist throughout changes in consciousness; and conscious episodes of acknowledging the truth of a proposition. What is the relationship between these two kinds of attitude? Normally, the conscious episodes are in harmony with the underlying dispositions, but sometimes they come apart and we act in a way that is contrary to our explicit conscious judgements. Philosophers have often tried to explain (...) these situations in largely doxastic terms, by identifying one or other of the attitudes as our ‘real’ beliefs. This chapter argues that this is not generally realistic and we should appeal to a wider range of psychological attitudes. Such an account would be best supported by a picture of the unconscious mind which does not sharply separate the doxastic from the conative and the affective. (shrink)

Culling seems to be a cruel method of human interference in the lives of elephants. The method of culling is generally used to control population numbers of highly developed mammals to protect vegetation and habitat for other less important species. Many people are against human interference in the lives of elephants. In this article aspects of this highly controversial issue are explored. Three fascinating characteristics of this ethical dilemma are discussed in the introductory part, and then the major arguments raised (...) against human interference in the lives of elephants are evaluated. These arguments are the following: First, that nature should be allowed to run its course and establish its own balance; nature will thus solve the problem of elephant overpopulation. The second argument raised by animal-rights activists as well as by animal-welfare groups either claim that animals have rights that humans must respect at all times, or that all sentient beings have interests that humans ought to respect, as those beings can experience pleasure or pain. The third argument often associates culling elephants as method for population control with the commercial use and exploitation of wilderness areas. Many people argue that it is unethical to use wildlife as a sustainable resource for fighting poverty. In conclusion it is stated that despite these arguments human intervention in the lives of elephants are ethically justified. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant (...) future; catastrophe trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

The performance of natural behavior is commonly used as a criterion in the determination of animal welfare. This is still true, despite many authors having demonstrated that it is not a necessary component of welfare –some natural behaviors may decrease welfare, while some unnatural behaviors increase it. Here I analyze why this idea persists, and what effects it may have. I argue that the disagreement underlying this debate on natural behavior is not one about which conditions affect welfare, but a (...) deeper conceptual disagreement about what the state of welfare actually consists of. Those advocating natural behavior typically take a “teleological” view of welfare, in which naturalness is fundamental to welfare, while opponents to the criterion usually take a “subjective” welfare concept, in which welfare consists of the subjective experience of life by the animal. I argue that as natural functioning is neither necessary nor sufficient for understanding welfare, we should move away from the natural behavior criterion to an alternative such as behavioral preferences or enjoyment. This will have effects in the way we understand and measure welfare, and particularly in how we provide for the welfare of animals in a captive setting. (shrink)

There is an under-appreciated tradition of genealogical explanation that is centrally concerned with social functions. I shall refer to it as the tradition of pragmatic genealogy. It runs from David Hume (T, 3.2.2) and the early Friedrich Nietzsche (TL) through E. J. Craig (1990, 1993) to Bernard Williams (2002) and Miranda Fricker (2007). These pragmatic genealogists start out with a description of an avowedly fictional “state of nature” and end up ascribing social functions to particular building blocks of our (...) practices – such as the fact that we use a certain concept, or live by a certain virtue – which we did not necessarily expect to have such a function at all. That the seemingly archaic device of a fictional state-of-nature story should be a helpful way to get at the functions of our actual practices must seem a mystifying proposal, however; I shall therefore endeavor to demystify it in what follows. My aim in this chapter is twofold. First, by delineating the framework of pragmatic genealogy and contrasting it with superficially similar methods, I argue that pragmatic genealogies are best interpreted as dynamic models whose point is to reveal the function – and non-coincidentally often the social function – of certain practices. Second, by buttressing this framework with something it notably lacks, namely an account of the type of functionality it operates with, I argue that both the type of functional commitment and the depth of factual obligation incurred by a pragmatic genealogy depend on what we use the method for: the dynamic models of pragmatic genealogy can be used merely as heuristic devices helping us spot functional patterns, or more ambitiously as arguments grounding our ascriptions of functionality to actual practices, or even more ambitiously as bases for functional explanations of the resilience or the persistence of practices. By bringing these distinctions into view, we gain the ability to distinguish strengths and weaknesses of the method’s application from strengths and weaknesses of the method itself. (shrink)

This article offers a normative analysis of some of the most controversial incidents involving police—what I call police-generated killings. In these cases, bad police tactics create a situation where deadly force becomes necessary, becomes perceived as necessary, or occurs unintentionally. Police deserve blame for such killings because they choose tactics that unnecessarily raise the risk of deadly force, thus violating their obligation to prioritize the protection of life. Since current law in the United States fails to ban many bad tactics, (...) police- generated killings often are treated as “lawful but awful.” To address these killings, some call on changes to departmental policies or voluntary reparations by local governments, yet such measures leave in place a troubling gap between ethics and law. I argue that police-generated killings merit legal sanctions by appealing to a relevant analogy: self-generated self-defense, where the person who engages in self-defense started the trouble. The persistent lack of accountability for police-generated killings threatens life, police legitimacy, and trust in democratic institutions. The article closes by identifying tools in law and policy to address this challenge. (shrink)

The study area was a small lowland river valley (the Łęg river) located in the south-east of Poland. The object of investigation was the macrophytes of 10 river lakes with corresponding active river channel stretches of the same length as the cut-offs. The aim was to check the difference in species diversity between cut-off and active river channels. The second aim was to test the following hypothesis: vegetation of river lake has been shaped under the influence of contiguous river stretch (...) which has left a measurable mark in species abundance and composition. To test this, we checked whether a cut-off channel’s flora is more similar to flora of the contiguous river stretch, than to flora of a farther river stretch. During the course of the study it was found that the average species richness was approximately two times higher in the cut-off channels than in the river stretches. The number of the species exclusive for the river lakes was nine times higher in comparison with the river’s exclusives (not found in the cut-offs). The Shannon diversity index definitely spoke in favor of the river lakes. These results clearly show the significance of river lakes in maintaining biodiversity of aquatic ecosystems in a small river valley. We did not confirm our hypothesis concerning floristic relation between an active channel and its cut-offs. The floristic similarity between a given cut-off channel and the contiguous active river channel stretch is not stronger than the similarity between this lake and more distant river stretches. The cause of such a state of affairs may be high natural dynamics of investigated habitats and anthropogenic transformation of the river valley. (shrink)

In this article I respond to the obligation to institute the policy of decoupled crop subsidies as is provided in Pilchman’s article “Money for Nothing: Are decoupled Crop Subsidies Just?” With growing problems of poor nutrition in the United States there have been two different but related phenomenon that have appeared. First, the obesity epidemic that has ravaged the nation and left an increasing number of people very unhealthy; and second, the phenomenon of food deserts where individuals are unable to (...) access fresh fruits and vegetables. A possible solution to this problem, as has been proposed by some, is to institute a decoupled crop subsidy that would increase the production of fruits and vegetables in the United States. In this paper I explore the possible unintended consequences of this policy and how it may violate liberal international conceptions of justice. I conclude that there must be further empirical research before anyone can call decoupled crop subsidies an obligation to justice. (shrink)

Sven Rosenkranz’s Justification as Ignorance shows how a strongly internalist conception of justification can be derived from a strongly externalist conception of knowledge, given an identification of justification with second-order ignorance and a set of structural principles concerning knowing and being in a position to know. Among these principles is an epistemic analogue of the Geach modal schema which states that one is always in a position to know that one doesn’t know p or in a position to know that (...) one doesn’t know not-p. Even suitably refined, the principle faces a range of counterexamples in which it misleadingly and persistently seems to one that one knows whether p without it seeming to one that one knows p nor that one knows not-p. These cases also threaten the book’s case for the luminosity of second-order ignorance, which is in turn central to its derivation of strongly internalist principles of justification. (shrink)
