Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

The causal closure of the physical world is assumed everywhere in physics but has little empirical support within living organisms. For the spiritual to have effects in nature, and make a difference there, the laws of physical nature would have to be modified or extended. I propose that the renormalized parameters of quantum field theory (masses and charges) are available to be varied locally in order to achieve ends in nature. This is not adding extra forces to nature but rescaling (...) the forces which already exist. We separate metric time in 4 dimensions from process time as the order of actualization of potentialities. This is to allow iterative forward and reverse steps in metric time to influence intermediate variations in the vacuum permittivities to move charged bodies towards achieve specific targets at a later time. Then mental or spiritual influx could have effects in nature, and these should be measurable in biophysics experiments. With this proposal, we see after some centuries how ‘final causes’ could once again be seen active in nature. (shrink)

In order to link fine-tuning in physics with spiritual influx, I propose that the highest degree in physics is where ‘ends’ are received in physics. By ends, I refer to what it is that determines the means or causes in physics, and what it is that manages or influences to basis parameters (masses and charge values) of the quantum fields. This is fine-tuning, in the sense that it occurs not just for the whole universe (in the Big Bang, for example), (...) but locally. That is, this fine-tuning is different at each time, and in point in space. Thus this influx can be specific to living organisms, and can occur at all the needed scales and levels in psychology and biology, namely every day and every micros-second of our lives. (shrink)

Which way does causation proceed? The pattern in the material world seems to be upward: particles to molecules to organisms to brains to mental processes. In contrast, the principles of quantum mechanics allow us to see a pattern of downward causation. These new ideas describe sets of multiple levels in which each level influences the levels below it through generation and selection. Top-down causation makes exciting sense of the world: we can find analogies in psychology, in the formation of our (...) minds, in locating the source of consciousness, and even in the possible logic of belief in God.

Fragment B 1 of Parmenides describes a youth’s journey to the house of a goddess who enlightens him as to the nature of all things. The task of translating Parmenides’ Greek text is beset with many difficulties, most notably the phrase kata pant’ atê at B 1.3. There, the neuter accusative plural panta (‘all things’) combines with the feminine nominative singular atê (‘heaven sent blindness’) to render translation impossible. Some have proposed emending the text to read astê (‘down to all (...) cities’), understood in connection with the pathway of divine inspiration. Others reject the emendation in so far as the youth is said at B 1.27 to travel ‘far from the beaten path of men.’ I argue in defense of the reading kata pant’ a<s>tê in so far as references to pathways of inspiration and poetic journeys to the cities of men occur frequently in the poetry of Parmenides’ era.

Modern physics has cast doubt on Newton's idea of particles with definite properties. Do we have to go back to Aristotle for a new understanding of the ultimate nature of substance? If we ask, `what is the nature of substance?', we might be told that this substance is salt, that one is copper, or that the atomic nucleus is a mixture of protons and neutrons. But what are all these substances? What do they have in common which makes them substances? (...) We don't seem to think that such things as colours, numbers, or shapes are by themselves `substantial enough' to be substances in their own right. We therefore change our question to `what is it to be a substance?', or to `what is the ultimate nature of the simplest substances?'. (shrink)

In Posterior Analytics II 19 Aristotle likens the way in which sense perception gives rise to knowledge of the universal to the way in which one soldier’s ceasing his flight from the enemy leads other soldiers to do the same ‘heôs epi archên êlthen.’ Although the remark seems intended to characterize knowledge as the end result of an accumulative process, the concluding reference to ‘a starting point’ or archê has no clear meaning. I argue that the phrase can be plausibly (...) understood in light of Aristotle’s explanation of how a single calm thought can spread calm to other thoughts (Problems 917a29-33) and a single cloud can serve as a starting point (archê) for a revival of stormy weather (Problems 941a9-13). In addition, Aristotle elsewhere (e.g. Generation of Animals 788a13-16) speaks of the archê as the person or thing which initiates a process. Thus, when one soldier’s stopping causes another soldier to stop, this process can continue ‘until they come to the one who initiated the process.’ . (shrink)

State of nature theories have a long history and play a lively role in contemporary work. Theories of this kind share certain nontrivial commitments. Among these are commitments to inclusion of a Lockean proviso among the principles of justice and to an assumption of invariance of political principles across changes of circumstances. In this article I want to look at those two commitments and bring to light what I believe are some important difficulties they engender. For nonpattern state of nature (...) theories, the justness of a society is marked by the conformance of the society to procedural principles. Distributions of resources and the like have no particular import for questions of justice. Whatever may later result, so long as it came about in accordance with the rules determined by the principles of justice, is itself just. The Lockean proviso is one of the principles of justice governing property and other rights of nonpattern theories of justice. The proviso hangs as a "shadow" over the results of the operation of the other (usual) principles of justice. It is intended to remedy a complaint which arises when the positions of those no longer at liberty to use some resource are worsened (1) by no longer being able to use freely what they previously were free to use and (2) in such a way that they fall below a "baseline." Following Locke, a traditional formulation of the proviso is to allow acquisition just so long as there is "enough and as good" left over for others. Section I concerns the relation of the Lockean proviso to pattern and nonpattern principles of justice, demonstrating that a Lockean proviso turns a nonpattern into a pattern theory of justice. Section II is about the relation of the Lockean proviso to the ideas revealed by an examination of a state of nature, suggesting reasons to reject ideal theories of justice. (shrink)

In fragment B 18 (DK) Xenophanes asserts that ‘Not from the outset did the gods reveal all things to mortals’ but that ‘in time, as they seek, men discover better.’ The remark has been understood in different ways but is usually read as a rejection of the view of the gods as the givers of all good things and an expression of faith in the capacity of human beings to make progress through their own efforts. I argue that the ‘hymn (...) to progress’ reading of B 18 is unjustified by any other aspect of Xenophanes’ thought and at odds with his generally dour view of the intelligence and character of his fellow citizens. A detailed analysis of the fragment supports the view that Xenophanes is here rejecting belief in divine revelation through natural signs and affirming the value of historiê or inquiry in the form of travel and direct observation.

The cucumber is a creeping vine that roots in the ground and grows up trellises or other supporting frames, wrapping around supports with thin, spiraling tendrils. The plant may also root in a soilless medium, whereby it will sprawl along the ground in lieu of a supporting structure. The vine has large leaves that form a canopy over the fruits. Among these common diseases, we single out the diseases that affect the cucumber, which is affected by about 22 diseases, with (...) different symptoms for each disease. Today, technology is facilitating human life in all areas of life, and among these facilities are expert systems that have become an integral part of human life as they contain several systems and areas, for example: Artificial Intelligence (AI), which refers to systems or devices that simulate Human intelligence to perform tasks that can improve itself based on some human information, and other areas, and with reference to expert systems and their importance to humans, an integrated expert system has been created in the agricultural field that diagnoses cucumber diseases using CLIPS Expert System language Delphi language. The system was used to design and implement the proposed expert system. The system facilitates the diagnosis of cucumber-related diseases. There is no doubt that this expert system will help farmers and those involved in the agricultural field to diagnose cucumber-related diseases. Objectives: is to help farmers diagnose pear diseases in the correct way and how to treat these diseases. Method: The system contains a program that diagnoses 22 diseases that affect cucumber. Results: The expert system was evaluated by farmers and praised for helping them with it. Conclusion: The expert system for diagnosing cucumber diseases is effective and usable. (shrink)

Given the fact of moral disagreement, theories of state neutrality which rely on moral premises will have limited application, in that they will fail to motivate anyone who rejects the moral premises on which they are based. By contrast, contractarian theories can be consistent with moral scepticism, and can therefore avoid this limitation. In this paper, I construct a contractarian model which I claim is sceptically consistent and includes a principle of state neutrality as a necessary condition. The principle of (...) neutrality which I derive incorporates two conceptions of neutrality which have usually been thought of as distinct and incompatible. I argue that contractarianism gives us a unified account of these concep- tions. Ultimately, the conclusion that neutrality can be derived without violating the constraint established by moral scepticism turns out to rely on an assumption of equal precontractual bargaining power. I do not attempt to defend this assumption here. If the assumption cannot be defended in a sceptically consistent fashion, then the argument for neutrality given here is claimed to be morally minimal, rather than fully consistent with moral scepticism.

A naturalistic theory of intentionality is proposed that differs from previous evolutionary and tracking theories. Full-blown intentionality is constructed through a series of evolvable refinements. A first, minimal version of intentionality originates from a conjectured internal process that estimates an organism’s own fitness and that continually modifies the organism. This process produces the directedness of intentionality. The internal estimator can be parsed into intentional components that point to components of the process that produces fitness. It is argued that such intentional (...) components can point to mistaken or non-existing entities. Different Fregian senses of the same reference correspond to different components that have different roles in the estimator. Intentional components that point to intentional components in other organisms produce directedness towards semi-abstract entities. Finally, adding a general, population-wide means of communication enables intentional components that point to fully abstract entities. Intentionality thus naturalized has all of its expected properties: being directed; potentially making errors; possibly pointing to non-existent, abstract, or rigid entities; capable of pointing many-to-one and one-to-many; distinguishing sense and reference; having perspective and grain; and having determinate content. Several examples, such as ‘swampman’ and ‘brain-in-a-vat’, illustrate how the theory can be applied. (shrink)

This essay considers the nature of duties incumbent on legislators in virtue of the office itself. I argue that there is no duty for a legislator to enact a criminal law based on morality; there is no duty to incorporate substantive moral conditions into the criminal law; and there is therefore no duty derivable from the nature of the legislative office itself to make conditions of culpability depend on those of moral responsibility. Finally, I argue that the relation between morality (...) and the criminal law is therefore much less direct than assumed in most theories of the criminal law. (shrink)

Is there a place in scientific inquiry for guessing? Jonathan Cohen has recently argued that resorting to guesswork entails a loss of objectivity and regard for evidence which are essential to proper scientific investigation. I assess the merits of Cohen’s view first by taking as a test case Aristotle’s positive view of the role of guesswork (anchinoia) and conjecture (eustochia) in the search for the connections essential to the construction of scientific demonstrations. I then argue contra Cohen that one can (...) usefully employ guesswork while also employing reason; that it is possible to guess either intelligently or mindlessly; and consequently, that the use of guesswork need not represent a diminution in respect for the objectivity essential to scientific investigation. Although I would not claim that guesswork has a role to play in all scientific inquiry, there appear to be some datable instances of the useful and respectable scientific guess. (shrink)

The causal efficacy of a material system is usually thought to be produced by the law-like actions and interactions of its constituents. Here, a specific system is constructed and explained that produces a cause that cannot be understood in this way, but instead has novel and autonomous efficacy. The construction establishes a proof-of-feasibility of strong emergence. The system works by utilizing randomness in a targeted and cyclical way, and by relying on sustained evolution by natural selection. It is not vulnerable (...) to standard arguments against strong emergence, in particular ones that assume that the physical realm is causally closed. Moreover, it does not suffer from epiphenomenalism or causal overdetermination. The system uses only standard material components and processes, and is fully consistent with naturalism. It is discussed whether the emergent cause can still be viewed as ‘material’ in the way that term is commonly understood. (shrink)

Addressing the question of how medicine should engage with people who consider their clinical disease condition to be importantly constitutive of their identity, this article focuses on one group—advocates for the fat acceptance (FA) or body positivity movement in American society. Drawing on philosophical analysis, I try to show that FA and physician communities represent different traditions within the larger culture and that whether obesity should be considered a disease is a culture battle. I argue that diseases (medical) and illnesses (...) (cultural) are 2 different designations of clinical symptoms and that both disease and illness designations can change over time or be uncertain.

A new theory that naturalizes biological function is explained and compared with earlier etiological and causal role theories. Etiological theories explain functions from how they are caused over their evolutionary history. Causal role theories analyze how functional mechanisms serve the current capacities of their containing system. The new proposal unifies the key notions of both kinds of theories, but goes beyond them by explaining how functions in an organism can exist as factors with autonomous causal efficacy. The goal-directedness and normativity (...) of functions exist in this strict sense as well. The theory depends on an internal physiological or neural process that mimics an organism’s fitness, and modulates the organism’s variability accordingly. The structure of the internal process can be subdivided into subprocesses that monitor specific functions in an organism. The theory matches well with each intuition on a previously published list of intuited ideas about biological functions, including intuitions that have posed difficulties for other theories.

The number of police departments carrying Narcan keeps increasing at a fast pace throughout the U.S., as it is considered an effective measure to fight the opioid epidemic. However, there have been strong oppositions to the idea of the police Narcan use. Still, in 2018, the nation is debating about it. Though not clearly visible to the public, there are important ethical arguments against the police Narcan use which necessarily involve understanding of the ethical roles and responsibilities of police as (...) the law enforcement agency and apprehension of the moral status of a non-therapeutic opioid use. The authors of the paper investigate, primarily, the existing ethical controversies surrounding the police Narcan use while touching upon the issue of the decriminalizing drug policy in the U.S. The authors conclude that the police can carry and administer Narcan without self-contradiction and that the policymakers’ investigation on the drug decriminalization policy should begin with the understanding of the “common morality” of the American public, the ethical view shared and practiced by the greatest number of people.

The 2017 story of Charlie Gard is revisited. Upon the British High Court’s ruling in favor of the physicians that the infant should be allowed to die without the experimental treatment, the view of the public as well as the opinions of bioethicists and Catholic bishops are divided, interestingly along with a cultural line. American bioethicists and Catholic bishops tend to believe that the parents should have the final say while British/European bioethicists and Catholic bishops in general side with the (...) court’s decision. The paper explores the place of culture in bioethical reasoning between the UK/Europe and the US while claiming that cultural differences are more important than geopolitical or religious differences to understand the bioethical positions of a group. In addition, the authors introduce a decision-making program for handicapped neonates which is developed by the American Jesuit Bioethicist, Richard McCormick, and modified further by the contemporary American Jesuit Bioethicist, Peter A. Clark, in an attempt to see if the program’s normatizing categories can contribute to the culture-laden ethical discussions on Charlie’s case. However, it is admitted that the McCormick-Clark device is borne out of the American and Catholic theological context. (shrink)

This paper is a study about Philadelphia’s comprehensive user engagement sites (CUESs) as the authors address and examine issues related to the upcoming implementation of a CUES while seeking solutions for its disputed questions and plans. Beginning with the federal drug schedules, the authors visit some of the medical and public health issues vis-à-vis safe injection facilities (SIFs). Insite, a successful Canadian SIF, has been thoroughly researched as it represents a paradigm for which a Philadelphia CUES can expand upon. Also, (...) the existing criticisms against SIFs are revisited while critically unpackaged and responded to in favor of the establishment. In the main section, the authors propose the layout and services of the upcoming CUES, much of which would be in congruent to Vancouver’s Insite. On the other hand, the CUES would be distinct from Insite, as the authors emphasize, in that it will offer an information center run by individuals in recovery and place additional emphasis on early education for young healthcare professionals by providing them a platform to work at the site. The paper will also briefly investigate the implementation of a CUES site under an ethical scope of the Harm Reduction Theory. Lastly, the authors recommend some strategic plans that the Philadelphia City government may consider employing at this crucial stage. (shrink)

Recent studies show that racism still exists in the American medical profession, the fact of which legitimizes the historically long-legacy of mistrust towards medical profession and health authorities among African Americans. Thus, it was suspected that the participation of black patients in end-of-life care has always been significantly low stemmed primarily from their mistrust of the medical profession. On the other hand, much research finds that there are other reasons than the mistrust which makes African Americans feel reluctant to the (...) end-of-life care, such as cultural-religious difference and genuine misunderstanding of the services. If so, two crucial questions are raised. One is how pervasive or significant the mistrust is, compared to the other factors, when they opt out of the end-of-life care. The other is if there is a remedy or solution to the seemingly broken relationship. While no studies available answer these questions, we have conducted an experiment to explore them. The research was performed at two Philadelphia hospitals of Mercy Health System, and the result shows that Black patients’ mistrust is not too great to overcome and that education can remove the epistemic obstacles as well as overcome the mistrust.

Ebola is a deadly disease with no cure; there is no vaccine developed yet. Many died during the 2014 outbreak in West Africa, and many healthcare professionals went to the virus infected area to treat the patients while placing their lives in danger.

When unexpected outbreaks of the (...) virus occur in the places, the doctor(s) would encounter medical and ethical dilemmas. Should they leave or stay? In fact, this dilemma is not confined to the Ebola pandemic but relevant to all similar cases.

An explorative contribution to the ongoing discussion of thought experiments. While endorsing the majority view that skepticism about thought experiments is not well justified, in what follows we attempt to show that there is a kind of “bodiliness” missing from current accounts of thought experiments. That is, we suggest a phenomenological addition to the literature. First, we contextualize our claim that the importance of the body in thought experiments has been widely underestimated. Then we discuss David Gooding's work, which contains (...) the only explicit recognition of the importance of the body to understanding thought experiments. Finally, we introduce a phenomenological perspective of the body, which will give us the opportunity to sketch the power and promise of a phenomenological approach to thought experiments. (shrink)

The Deaf culture in the United States is a unique culture that is not widely understood. To members of the Deaf community in the United States, deafness is not viewed as a disease or pathology to be treated or cured; instead it is seen as a difference in human experience. Members of this community do not hide their deafness; instead they take great pride in their Deaf identity. The Deaf culture in the United States is very communitarian not individualistic. Mary (...) Beth and Dominic are a married couple in their late 20s who are genetically deaf. They are active members in the Deaf community and work as advocates for individuals who are deaf, family members of Deaf people and sign language interpreters who identify with the Deaf culture. Mary Beth and Dominic approach the fertility clinic with a request that they only want a child with the genetic gene for deafness. They would want the embryos that do not have the gene to be destroyed. This would entail creating a child who would have the gene for deafness. Medically and ethically, should the fertility clinic agree to the couple’s request? The authors argue that the couple's request should be denied and provide reasons for it from the perspectives of foundational and clinical ethics. (shrink)

As the Zika virus pandemic continues to bring worry and fear to health officials and medical scientists, Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) have recommended that residents of the Zika-infected countries, e.g., Brazil, and those who have traveled to the area should delay having babies which may involve artificial contraceptive, particularly condom. This preventive policy, however, is seemingly at odds with the Roman Catholic Church’s position on the contraceptive. As least since the promulgation of (...) Paul VI’s 1968 encyclical, Humanae Vitae, the Church has explicitly condemned artificial birth control as intrinsic evil. However, the current pontiff, Pope Francis, during his recent visit to Latin America, remarked that the use of artificial contraception may not be in contradiction to the teaching of Humanae Vitae while drawing a parallel between the current Zika Crisis and the 1960’s Belgian Congo Nun Controversy. The pope mentioned that the traditional ethical principle of the lesser of two evils may be the doctrine that justified the exceptions. The authors of this paper attempt to expand the theological rationale of the pope’s suggestion. In so doing, the authors rely on casuistical reasoning as an analytic tool that compares the Belgian Congo Nun case and the given Zika case, and suggest that the former is highly similar to, if not the same as, the latter in terms of normative moral feature. That is, in both cases the use of artificial contraception is theologically justified in reference to the criteria that the doctrine of the lesser of two evils requires. The authors wish that the paper would provide a solid theological-ethical ground based on which condom-use as the most immediate and effective preventive measure can be recommended in numerous Catholic hospitals as well as among Catholic communities in the world, particularly the most Zika-affected and largest Catholic community in the world, Brazil – 123 million present Brazilian citizens are reported to be Roman Catholic.

Plant diseases are numerous in the world of agriculture. These diseases cause a lot of trouble to most farmers. Among these common diseases, we single out the diseases that affect the Passion fruit, which is affected by about seven diseases, with different symptoms for each disease. Today, technology is facilitating human life in all areas of life, and among these facilities are expert system, a computer program that uses artificial-intelligence methods to solve problems within a specialized domain that ordinarily requires (...) human expertise. The first expert system was developed in 1965 by Edward Feigen Baum and Joshua Lederberg of Stanford University in California, U.S. Dendral, as their expert system was later known, was designed to analyses chemical compounds. Expert systems now have commercial applications in fields as diverse as medical diagnosis, petroleum engineering, and financial investing and other areas, and with reference to expert systems and their importance to humans, an integrated expert system has been created in the agricultural field that diagnoses Passion diseases using CLIPS Expert System language. The system was used to design and implement the proposed expert system. The system facilitates the diagnosis of Passion -related diseases. There is no doubt that this expert system will help farmers and those involved in the agricultural field to diagnose Passion -related diseases. Objectives: is to help farmers diagnose Passion diseases in the correct way and how to treat these diseases. Method: The system contains a program project that diagnoses 7 diseases that affect Passion and the seven diseases are: Brown spot, Septoria spot, Root and crown rot, Fusarium wilt, Anthracnose, Woodiness virus, Scab. Results: The expert system was evaluated by farmers and praised for helping them with it. Conclusion: The expert system for diagnosing Passion diseases is effective and usable. (shrink)

The origin and development of consciousness is poorly understood. Although it is clearly a naturalistic phenomenon evolved through Darwinian evolution, explaining it in terms of physicochemical, neural, or symbolic mechanisms remains elusive. Here I propose that two steps had to be taken in its evolution. First, living systems evolved an intrinsic goal-directedness by internalizing Darwinian fitness as a self-estimated fitness. The self-estimated fitness participates in a feedback loop that effectively produces intrinsic meaning in the organism. Second, animals with advanced nervous (...) systems evolved a special form of communication that modifies the way each partner estimates fitness. The resulting change in intrinsic meaning is experienced subjectively as a primary form of consciousness. This primary form is subsequently used to generate, partly through internalized dialogue, more complex forms of consciousness, such as consciousness of the natural and social worlds, consciousness of the self, and language-dependent forms of consciousness. An updated version of the theory in this paper can be found as Chapter 12 ('Consciousness') in my book 'The estimator theory of life and mind: how agency and consciousness can emerge', see VANTET-8 at philpapers .

Recently developed extensions of evolutionary theory are used to explain the human self as an evolved, unitary, and purposeful phenomenon. A basic mechanism that can generate life's agency and goal-directedness is combined with mechanisms that can account for awareness by and of the self, and for the social characteristics of humans. The new theory is largely consistent with major existing theories of the self, in particular theories centred on self-esteem, self-determination theory, and terror management theory. It can therefore be regarded (...) as a meta-theory that brings these theories, and related ones, within a common evolutionary framework. The theory suggests two primary dimensions of the self, the depth of awareness of the self and the social extent of the self.

The paper attempts to set a guideline to contemporary common morality debate. The author points out what he sees as two common problems that occur in the field of comparative cultural studies related to a common morality debate. The first problem is that the advocates and opponents of common morality, consciously or unconsciously, define the moral terms in question in a way that their respective meanings would naturally lead to the outcomes that each party desires. The second problem is that (...) the examples each party chooses as the empirical evidences may not be as simple and clear-cut as the researchers think they are, mainly because the situational contexts where the examples are located between two different cultures vastly differ. To prevent these mistakes, the author emphasizes that we should pay attention to a subtle distinction between "thick" and "thin" construed from the levels of "theoretical status" and of "material content". With the conceptual distinctions in mind, the author shows how different cultures (i.e., Western individualist society and East Asian neo-Confucian society) see the moral principles like autonomy and beneficence in different lexical orders.

Increasing behavioural evidence suggests that expert video game players (VGPs) show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear. We administered the Poffenberger paradigm with concurrent electroencephalogram (EEG) recording to assess occipital N1 latencies and interhemispheric transfer time (IHTT) in expert VGPs. Participants comprised 15 right-handed male expert VGPs and 16 non-VGP controls matched for age, handedness, IQ and years of education. Expert VGPs began playing before age 10, had a minimum 8 years experience, and (...) maintained playtime of at least 20 hours per week over the last 6 months. Non-VGPs had little-to-no game play experience (maximum 1.5 years). Participants responded to checkerboard stimuli presented to the left and right visual fields while 128-channel EEG was recorded. Expert VGPs responded significantly more quickly than non-VGPs. Expert VGPs also had significantly earlier occipital N1s in direct visual pathways (the hemisphere contralateral to the visual field in which the stimulus was presented). IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. No significant between-group differences in electrophysiological estimates of IHTT were found. Shorter N1 latencies may enable expert VGPs to discriminate attended visual stimuli significantly earlier than non-VGPs and contribute to faster responding in visual tasks. As successful video-game play requires precise, time pressured, bimanual motor movements in response to complex visual stimuli, which in this sample began during early childhood, these differences may reflect the experience and training involved during the development of video-game expertise, but training studies are needed to test this prediction.

Reductive intellectualists hold that knowledge-how is a kind of knowledge-that. For this thesis to hold water, it is obviously important that knowledge-how and knowledge-that have the same epistemic properties. In particular, knowledge-how ought to be compatible with epistemic luck to the same extent as knowledge-that. It is argued, contra reductive intellectualism, that knowledge-how is compatible with a species of epistemic luck which is not compatible with knowledge-that, and thus it is claimed that knowledge-how and knowledge-that come apart.

A common epistemological assumption in contemporary bioethics held b y both proponents and critics of non-traditional forms of cognitive enhancement is that cognitive enhancement aims at the facilitation of the accumulation of human knowledge. This paper does three central things. First, drawing from recent work in epistemology, a rival account of cognitive enhancement, framed in terms of the notion of cognitive achievement rather than knowledge, is proposed. Second, we outline and respond to an axiological objection to our proposal that draws (...) from recent work by Leon Kass (2004), Michael Sandel (2009), and John Harris (2011) to the effect that ‘enhanced’ cognitive achievements are (by effectively removing obstacles to success) not worthy of pursuit, or are otherwise ‘trivial’. Third, we show how the cognitive achievement account of cognitive enhancement proposed here fits snugly with recent active externalist approaches (e.g., extended cognition) in the philosophy of mind and cognitive science.

According to reductive intellectualism, knowledge-how just is a kind of propositional knowledge (e.g., Stanley & Williamson 2001; Stanley 2011a, 2011b; Brogaard, 2008a, 2008b, 2009, 2011, 2009, 2011). This proposal has proved controversial because knowledge-how and propositional knowledge do not seem to share the same epistemic properties, particularly with regard to epistemic luck. Here we aim to move the argument forward by offering a positive account of knowledge-how. In particular, we propose a new kind of anti-intellectualism. Unlike neo-Rylean anti-intellectualist views, according (...) to which the possession of knowledge-how is just a matter of possessing certain abilities, we submit that knowledge-how is a particular kind of cognitive achievement attained just when cognitive ability is connected in the right way with successful performance.

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then examine first (...) the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.

A critical analysis of Alfred Schuetz' conception of rationality based upon Edmund Husserl's phenomenology.

The classical theory of probability has long been abandoned and is seen by most philosophers as a non-contender—a mere precursor to newer and better theories. In this paper I argue that this is a mistake. The main reasons for its rejection—all related to the notorious principle of indifference—are that it is circular, of limited applicability, inconsistent, and dependent upon unjustified empirical assumptions. I argue that none of these claims is true and that the classical theory remains to be refuted.

What are the properties of composite objects, and how do the properties of composite objects and the properties of their proper parts relate to one another? The answers to these questions depend upon which view of composition one adopts. One view, which I call the orthodox view, is that composite objects are numerically distinct from their proper parts, individually and collectively. Another view, known as composition as identity, is that composite objects are numerically identical to their proper parts, taken together. (...) I argue that the orthodox view entails that the intuitive picture of composite objects and their properties that most accept is false. Not so for composition as identity. I also show that all of the available alternatives face serious difficulties. This puts composition as identity at an advantage over the orthodox view, at least when it comes to accounting for the properties of composite objects. (shrink)

In a recent paper Shieva Kleinschmidt has argued that if certain scenarios involving extended simple regions are possible (so-called ‘Place Cases’), then no logic of location with only one primitive locative notion (i.e., no ‘parsimonious logic of location’) will suffice to describe all of the locative possibilities. Since almost all existing logics of location are parsimonious (and apparently for good reason) the argument is a considerable obstacle to the development of a satisfactory logic of location. Kleinschmidt suggests that the best (...) way out of the difficulty is to deny the possibility of Place Cases by denying that extended simple regions are possible. I argue that much the same problem arises even in cases not involving extended simple regions or indeed exotic regions of any kind. Thus, simply denying the possibility of extended simple regions will not save parsimonious logics of location. (shrink)

Perhaps the most commonly discussed argument against the possibility of extended simples is the argument from heterogeneity. The argument states that, if extended simples are possible, then extended simples which exhibit intrinsic qualitative variation across space (or spacetime) are also possible [Premise 1]. But, the argument goes, it is impossible for an extended simple to exhibit intrinsic qualitative variation across space (or spacetime) [Premise 2]. Thus, extended simples are impossible. I argue that there is a serious problem with the argument (...) from heterogeneity: the best arguments in support of the first premise undermine support for the second. Thus, there appears to be no good reason to accept both premises. (shrink)

We argue that, insofar as one accepts either supersubstantivalism or strong composition as identity for the usual reasons, one has (defeasible) reasons to accept the other as well. Thus, all else being equal, one ought to find the package that combines both views—the Identity Package—more attractive than any rival package that includes one, but not the other, of either supersubstantivalism or composition as identity.

While it is widely regarded that intellectual humility is among the intellectual virtues, there is as of yet little consensus on the matter of what possessing and exercising intellectual humility consists in, and how it should be best understood as advancing our epistemic goals. For example, does intellectual humility involve an underestimation of one’s intellectual abilities, or rather, does it require an accurate conception? Is intellectual humility a fundamentally interpersonal/social virtue, or might it be valuable to exercise in isolation? To (...) what extent does intellectual humility demand of us an appreciation of how the success of our inquiries depends on features of our social and physical environment beyond our control? These are just a few of the many questions that are crucial to getting a grip on this intellectual virtue and why we might aspire to cultivate it. Furthermore, and apart from the nature and value of humility, it is worthwhile to consider how this notion, properly understood, might have import for other philosophical debates, including those about (for example) scepticism, assertion, epistemic individualism and anti-individualism, and the philosophy of education. This special issue brings together a range of different philosophical perspectives on these and related questions to do with intellectual humility with an aim to contributing to this important and timely topic.

Almost all philosophers interested in parthood and composition think that a composite object is a further thing, numerically distinct from the objects that compose it. Call this the orthodox view. I argue that the orthodox view is false, and that a composite object is identical to the objects that compose it (collectively). This view is known as composition as identity. -/- I argue that, despite its unpopularity, there are many reasons to favour com- position as identity over the orthodox view. (...) First, defenders of the orthodox view have not offered complete theories of composition. For instance, they have not given adequate accounts of heterogeneous properties like being black and white in composite objects. Nor have they given satisfactory explanations for the necessary connections that hold between composite objects and their proper parts. -/- Second, there appears to be no good way for defenders of the orthodox view to remedy this. Any account of the heterogeneous properties of composite objects which is compatible with the orthodox view faces serious problems, as does any account of the necessary connections between an object and its proper parts. Composition as identity, on the other hand, is compatible with intuitive responses to both of these challenges. -/- Third, there are a number of strong arguments in favour of composition as identity. For example, composition as identity fits our evidence about the way the world is better than the orthodox view does. It also allows us to easily maintain that composition sometimes occurs and sometimes does not—i.e., it allows us to easily maintain that composition is restricted. The orthodox view does not. The theories of composition put forward by most philosophers are at best incomplete or in need of improvement. At worst, they are false and composition as identity is true. (shrink)

Some stories of moral exemplars motivate us to emulate their admirable attitudes and behaviors, but why do some exemplars motivate us more than others? We systematically studied how motivation to emulate is influenced by the similarity between a reader and an exemplar in social or cultural background (Relatability) and how personally costly or demanding the exemplar’s actions are (Attainability). Study 1 found that university students reported more inspiration and related feelings after reading true stories about the good deeds of a (...) recent fellow alum, compared to a famous moral exemplar from decades past. Study 2A developed a battery of short moral exemplar stories that more systematically varied Relatability and Attainability, along with a set of non-moral exemplar stories for comparison. Studies 2B and 2C examined the path from the story type to relatively low stakes altruism (donating to charity and intentions to volunteer) through perceived attainability and relatability, as well as elevation and pleasantness. Together, our studies suggest that it is primarily the relatability of the moral exemplars, not the attainability of their actions, that inspires more prosocial motivation, at least regarding acts that help others at a relatively low cost to oneself.
