Common everyday materials such as textiles, foodstuffs, soil or skin can have complex, mutable and varied appearances. Under typical viewing conditions, most observers can visually recognize materials effortlessly, and determine many of their properties without touching them. Visual material perception raises many fascinating questions for vision researchers, neuroscientists and philosophers, yet has received little attention compared to the perception of color or shape. Here we discuss some of the challenges that material perception raises and argue that further philosophical thought should (...) be directed to how we see materials. (shrink)

RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

Experiments with remote perception and Random Event Generators (REG) performed over the last decades show small but significant anomalous effects. Since these effects seem to be independent of spatial and temporal distance, they appear to be in disagreement with the standard scientific worldview. A very simple explanation of quantum mechanics is pre- sented, rejecting all unjustified claims about the world. A view of mind in agreement with cognitive neuroscience is introduced. It is argued that mind and consciousness are emer- gent (...) properties of the brain and are understandable without any nonphysical assumptions. A plausible explanation of the results of anomalous experiments, based on the concept of synchronicity, introduced by C.G. Jung and advocated by W. Pauli, is offered. A proof is given that strong correlations should exist between any systems that once interacted. Synchronicity events between parts of the brain and physical objects may be sufficient to explain the results of anomalous experiments. Standard physics is sufficient to understand these phenomena.

Metacognition is the capacity to evaluate the success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that is applied to different tasks or if self-evaluative processes are domain specific. Here, we investigated this issue directly by examining the neural substrates engaged when metacognitive judgments were made by human participants of both sexes during perceptual and memory tasks matched for stimulus and performance characteristics. By comparing patterns (...) of fMRI activity while subjects evaluated their performance, we revealed both domain-specific and domain-general metacognitive representations. Multivoxel activity patterns in anterior prefrontal cortex predicted levels of confidence in a domain-specific fashion, whereas domain-general signals predicting confidence and accuracy were found in a widespread network in the frontal and posterior midline. The demonstration of domain-specific metacognitive representations suggests the presence of a content-rich mechanism available to introspection and cognitive control. (shrink)

The problem with reductionism in biology is not the reduction, but the implicit attitude of determinism that usually accompanies it. Methodological reductionism is supported by deterministic beliefs, but making such a connection is problematic when it is based on an idea of determinism as fixed predictability. Conflating determinism with predictability gives rise to inaccurate models that overlook the dynamic complexity of our world, as well as ignore our epistemic limitations when we try to model it. Furthermore, the assumption of a (...) strictly deterministic framework is unnecessarily hindering to biology. By removing the dogma of determinism, biological methods, including reductive methods, can be expanded to include stochastic models and probabilistic interpretations. Thus, the dogma of reductionism can be saved once its ties with determinism are severed. In this paper, I analyze two problems that have faced molecular biology for the last 50 years—protein folding and cancer. Both cases demonstrate the long influence of reductionism and determinism on molecular biology, as well as how abandoning determinism has opened the door to more probabilistic and unconstrained reductive methods in biology.

There is a conflict between a strictly political approach to LGBT rights, in which the battle must never cease. and the less encountered notion that individuals can let the battle settle into the background and simply get on with unpolitical life. at least unpolitical at home. The article takes the example of India as a salient place to view this conflict. As a democratic nation, India has had some limited progress in protecting LGBT rights. How its massively differentiated and traditional (...) society has adopted and tolerated this moral enjoinder is another matter. Certainly, acceptance is as important as legal recognition. But how are the politics faring at the individual level? One of the best media for feeling a nation’s political pulse is not internet or television but literature. Two current Indian authors exemplify how, at the personal level, some sexual politicking has already succeeded, in some social realms, by almost disappearing from the narrative. (shrink)

Most current dental ethics curricula use a deontological approach to biomedical and dental ethics that emphasizes adherence to duties and principles as properties that determine whether an act is ethical. But the actual ethical orientation of students is typically unknown. The purpose of the current study was to determine the ethical orientation of dental students in resolving clinical ethical dilemmas. First-year students from one school were invited to participate in an electronic survey that included eight vignettes featuring ethical conflicts common (...) to the health care setting. The Multidimensional Ethics Scale was used to evaluate the students’ ethical judgments of these conflicts. Students rated each vignette along 13 ethically relevant items using a 7-point scale. Nine of the thirteen items were analyzed because they represent the dominant ethical theories, including deontology. One hundred sixteen dental students successfully completed the survey. Of the analyzed items, those associated with deontology had comparatively weak associations with whether students judged the action to be ethical and whether students judged themselves likely to perform the action. Whether an action was judged to be caring had the strongest association with whether the action was judged to be ethical and whether students judged themselves likely to perform the action. These results suggest that adherence to duties or principles has weaker association with students’ ethical judgments and behavior compared to caring, which was found to be more influential in their ethical judgments and behavior. Current dental school curricula with a primary focus on deontology may no. (shrink)

Despite the United Nations Declaration of the Rights of Indigenous Peoples, assimilationist policies continue, whether official or effective. Such policies affect more than the right to group choice. The concern is whether indeed genocide or “only” ethnocide (or culturecide)—the elimination of a traditional culture—is at work. Discussions of the distinction between the two terms have been inconsistent enough that at least one commentator has declared that they cannot be used in analytical contexts. While these terms, I contend, have distinct senses, (...) yet in cases of governmental and other institutional assimilationist policy for indigenous peoples, such ethnocide effectively entails genocide. Insofar as any people’s cultural practices and beliefs are essential for life and health, individuals in groups value, if tacitly, their culture as highly as their language or any artifact: Thus, attempts to eradicate a culture through assimilation in fact eradicate individuals’ lives and health and so are effectively murderous. Acknowledgement by worldwide organizations that assimilationist ethnocide is effectively genocide should affect policy concerning indigenous peoples and thus has significance for international law.

A dissociated area of medical research warrants bioethical consideration: a proposed transplantation of a donor’s entire body, except head, to a patient with a fatal degenerative disease. The seeming improbability of such an operation can only underscore the need for thorough bioethical assessment: Not assessing a case of such potential ethical import, by showing neglect instead of facing the issue, can only compound the ethical predicament, perhaps eroding public trust in ethical medicine. This article discusses the historical background of full-body (...) transplantation, documents the seriousness of its current pursuit, and builds an argument for why prima facie this type of transplant is bioethically distinct. Certainly, this examination can only be preliminary, indicating what should be a wide and vigorous discussion among practitioners and ethicists. It concludes with practical suggestions for how the medical and bioethics community may proceed with ethical assessment. (shrink)

As engineers propose constructing humanlike automata, the question arises as to whether such machines merit human rights. The issue warrants serious and rigorous examination, although it has not yet cohered into a conversation. To put it into a sure direction, this paper proposes phrasing it in terms of whether humans are morally obligated to extend to maximally humanlike automata full human rights, or those set forth in common international rights documents. This paper’s approach is to consider the ontology of humans (...) and of automata and whether ontological difference between them, that pertains to the very bases of human rights, affects the latter’s claims to full human rights. Considering common bases of human rights, can these bases tell us whether a certain ontological distinction of humans from automata—or a de facto distinction about humans tacitly acknowledged by full-rights-recognizing societies—makes a difference in whether humans are morally obligated to assign these entities full rights? Human rights to security also arise. The conclusion is that humans need not be under any moral obligation to confer full human rights on automata. The paper’s ultimate point is not to close the discussion with this ontological cap but to set a solid moral and legal groundwork for opening it up tout court. (shrink)

Since the Nuremberg Code and the first Declaration of Helsinki, globally there has been increasing adoption and adherence to procedures for ensuring that human subjects in research are as well informed as possible of the study’s reasons and risks and voluntarily consent to serving as subject. To do otherwise is essentially viewed as violation of the human research subject’s legal and moral rights. However, with the recent philosophical concerns about responsible robotics, the limits and ambiguities of research-subjects ethical codes become (...) apparent on the matter of constructing automata that maximally resemble human beings (as defined hereunder). In this case, the automata themselves, as products of research and development, are in the very process of their construction subjects of research and development. However, such research faces a paradox: The subjects cannot give their informed consent to this research for their own development, although their consent would be needed for the research. According to ethical codes, this research would be unethical. The article then explores whether the background concepts giving rise to this paradox could be reframed in order to allow such research to proceed ethically. (shrink)

Over the past several decades environmental ethics has grown markedly, normative ethics having provided essential grounding in assessing human treatment of the environment. Even a systematic approach, such as Paul Taylor’s, in a sense tells the environment how it is to be treated, whether that be Earth’s ecosystem or the universe itself. Can the environment, especially the ecosystem, as understood through the study of ecology, in turn offer normative and applied ethics any edification? The study of ecology has certainly increased (...) awareness of the fact that it is not possible for a moral agent within the ecosystem to step outside its intricate mesh of actions and events, of causes and effects. That is, absolutely everything that an agent can do can have some, often unforeseeable, outcome in the environment. An incompletely snuffed-out match tossed out a car window can cause a forest fire, which causes biome destruction, which causes x, y, and z. In sum, the ecosystem can edify ethics in terms of the scope of ethics, which remains an unsettled, if too-often ignored, matter. By such an inclusive view of moral scope, as derived in part from ecology and as presented here, the scope of moral behavior would include—whether or not adventitiously—every action an agent may do. By this view, moral scope is, in essence, unlimited. The article offers some ramifications of this view of moral scope. (shrink)

The aspiration for volitional evolution, or human evolution directed by humans themselves,has increased in philosophical, scientific, technical, and commercial literature. The prospect of shaping the very being who is the consumer of all other innovations offers great commercial potential, one to which all other innovations would in effect be subservient. Actually an amalgam of projected technical/commercial developments, this prospective innovation has practical and ethical ramifications. However, because it is often discussed in a scientific way (specifically that of evolutionary theory), it (...) first calls for examination in terms of common scientific approaches to evolution. Yet, as evolutionary-theory controversies point up, evolution may be considered as neither a directed nor a directable process – a problem for the ontology of volitional evolution. One challenge for theories and programs aiming to implement the proposed innovation is then whether it is theoretically coherent. While I offer responses to the challenge in the form of objections, these in turn remain problematic. Two central issues of responsible innovation arise: (1) If this prospect were feasible, would it be responsible to implement it, and (2) if it is not even theoretically coherent, is it responsible for innovators, even this early-on, to keep promoting it as if it were?

An inequality in quantum mechanics, which does not appear to be well known, is derived by elementary means and shown to be quite useful. The inequality applies to 'all' operators and 'all' pairs of quantum states, including mixed states. It generalizes the rule of the orthogonality of eigenvectors for distinct eigenvalues and is shown to imply all the Robertson generalized uncertainty relations. It severely constrains the difference between probabilities obtained from 'close' quantum states and the different responses they can have (...) to unitary transformations. Thus, it is dubbed a master inequality. With appropriate definitions the inequality also holds throughout general probability theory and appears not to be well known there either. That classical inequality is obtained here in an appendix. The quantum inequality can be obtained from the classical version but a more direct quantum approach is employed here. A similar but weaker classical inequality has been reported by Uffink and van Lith. (shrink)

This article serves as either an addendum or as an expansion of ideas and work developed in my 2024 book, The Rationality Project: Across the Millennia, issued by Palgrave Macmillan. The book explores 21 potential theories for explaining rationality in terms of why and how one among these can serve in the position of explanatory power. The book does not fully explain all of these candidate theories, assigning that complete role to this addendum or work-in-progress. The main reason for this (...) abbreviation in assessing all the theories in the book is that the complete coverage—which this addendum allows—of all 21 theories would become too detailed for some philosophical readers. This addendum; one may consider, is then for the more technically minded reader—although certainly not-too-technically minded readers are welcome to explore it. If it becomes too bogged in detail for those latter kinds of readers, they may end up skimming the material in this addendum, trying at least to get the general idea of how these addendum sections fit into the book's goals.

Autonomy, equality and freedom often appear to be significantly interrelated with one another. However, it has been a challenge to unite these concepts. This article attempts to take up the challenge and demonstrate how these interrelate: .

Two Socratic dialogues often considered “comic”—Ion and Hippias Major—have also been contested as to their Platonic authenticity. Plato’s dialogues; while certainly engaging, can also seem grim in their philosophical intensity: At least one author has contended that the dialogue more firmly established as genuinely by Plato, Symposium; has some comic elements: This article goes a step further in suggesting that this dialogue does not merely have comic elements but is in fact a comedy. It draws on several texts in the (...) literature on Greek comedy over the past century and suggests that; although the dialogue sets itself serious philosophical challenges, its structure; style; and method are deeply steeped in comedic modes from around Plato’s day. This is not to presume whether Plato was deliberately writing a comedy. In general, writers are often strongly influenced by literary fashions of the day, so it would not be far stretching the matter to understand the work as comedic. Thereby, the article offers, via textual analysis, an argument for how the dialogue is a comedy along withcounter-arguments against such a notion. In the end, indeed, acknowledging it is a comedy promises to open up new angles on interpreting that dialogue. (shrink)

Recent years have seen a surge of interest in the question of whether humans should reproduce. Some say human life is too punishing and cruel to impose upon an innocent. Others hold that such harms do not undermine the great and possibly unique value of human life. Tracing these outlooks historically in the debate has barely begun. What might philosophers have said, or what did they say, about human life itself and its value to merit reproduction? This article looks to (...) Kant, who wrote much on whether, by reproducing, humans do wrong or right morally. It assesses two main arguments: one examining whether perfect or imperfect duties condone reproduction, the other whether Kant’s teleological or, in the opposite sense, his eschatological outlooks can salvage reproduction. These two arguments are essential for building the entire argument. This article finds that, although Kant’s arguments against reproducing are strong, some of his writing seems to support reproduction as a good. Yet, must we must assume an author, even one who strove for systematicity, must be consistent over his entire oeuvre on every issue, especially if not handled directly in a single work? The article concludes that Kant does not sufficiently, systematically support anti-natalism as more moral than pro-natalism. It is best for the current debate to grapple with the very dilemma that daunted Kant. (shrink)

Human-sciences research often focuses on social problems to create tools for solving them. Yet, in using common prejudices in gathering and sorting data on their subjects, they risk propagating those same prejudices. This article proposes that a major subject matter of human sciences is human concepts themselves. Concepts about “what we are,” individually and as a species, are deeply embedded, if not essential. It concludes that for greater precision, practitioners in human sciences must take maximum advantage of this characteristic of (...) the subject, making individuals’ concepts about what they consider themselves to be integral criteria of data gathering and sorting.

As to what distinguishes music from other sound, some investigators in both philosophy and cognitive scientists have answered “tonality.” It seems subservient even to rhythm. Tonality is considered to be the central factor around which the piece is oriented; it gives a sense of home, expectation, and completeness. Most important, much of this inquiry builds on naturalistic, evolutionary explanation to account for human nature and behavior. The conclusion of such line of thought is that sounds missing tonality or tonal focus (...) cannot be music. This article challenges such sort of naturalistic criteria distinguishing music from nonmusic. Permitting certain sets of sounds to be considered music does not necessitate denial or approval of naturalistic explanations but does allow nontonal music to serve a part of human and musical evolution.

If any area of current philosophy is so incendiary as to veer on violence, it is argument about a divide being’s existence. Hinman’s sober offering is possibly one of the most thorough apologetics in contemporary times, meriting serious consideration yet certain to draw fire. Since Darwin, the religious have taken up arms, both metaphorically and, in the case of World Trade Center and its imitators, literally. In turn, growing atheist movements reacted against such defensiveness. This upsurge in side-taking and regrouping (...) evidences a powerful human need for settling the issue. A peek at the arguments reveals a mess. One advantage of Hinman’s new work is that, among other goals, it attempts to order the mess. The work exudes care and some respect for the various perspectives. Its sheer breadth and depth of scholarship and capacity in articulating it attests the generally due respect of the many sides, which often exhibit the rational and irrational in one commentator. The central theme tying the various arguments together is that ideologies outside of the sciences’ themselves are informing science-based, evidential arguments about any divine’s existence. Many sides of the debate, including the monotheistic, are equally guilty. (shrink)

Care is more than dispensing pills or cleaning beds. It is about responding to the entire patient. What is called “bedside manner” in medical personnel is a quality of treating the patient not as a mechanism but as a being—much like the caregiver—with desires, ideas, dreams, aspirations, and the gamut of mental and emotional character. As automata, answering an increasing functional need in care, are designed to enact care, the pressure is on their becoming more humanlike to carry out the (...) function more effectively. The question becomes not merely whether the care automaton can effect good bedside manner but whether the patient’s response is not feeling deceived by the humanlikeness. It seems the device must be designed either to effect explicit mere human-“likeness,” thus likely undermining its bedside-manner potential, or to fool the patient completely. Neither option is attractive. This article examines the social problems of designing maximally humanlike care automata and how problems may start to erode the human rights of users/patients. The article then investigates the alternatives for dealing with this problem, whether by industrial and professional self-regulation or public-policy initiatives. It then frames the problem in the broader historical perspective in terms of previous bans, moratoria, and other means of control of hazardous and potentially rights-violating techniques and materials.

Conscious experiences involve subjective qualities, such as colours, sounds, smells and emotions. In this Perspective, we argue that these subjective qualities can be understood in terms of their similarity to other experiences. This account highlights the role of memory in conscious experience, even for simple percepts. How an experience feels depends on implicit memory of the relationships between different perceptual representations within the brain. With more complex experiences such as emotions, explicit memories are also recruited. We draw inspiration from work (...) in machine learning as well as the cognitive neuroscience of learning and decision making to make our case and discuss how the account could be tested in future experiments. The resulting findings might help to reveal the functions of subjective experience and inform current theoretical debates on consciousness. (shrink)

One of the most salient contemporary concerns in academic debates and pop culture alike is the extent to which new technologies may re-cast Homo sapiens. Species members may find themselves encased in a type of existence they deem to be wanting in comparison with their present form, even if the promised form was assured to be better. Plausibly, the concern is not merely fear of change or of the unknown, but rather it arises out of individuals’ general identification with what (...) they are and what their friends and family are. In altering that identity beyond a point, they lose it and thus lose themselves in a kind of living death. The three volumes analysed in this essay offer widely differing perspectives on the relations between humans and new technology. As the three works reviewed here together make clear, a whole, fully coherent, definitive work on the composite redesign of human nature (CROHN) still has yet to materialize. (shrink)

Thanks to mounting discussion about projected technologies’ possibly altering the species mentally and physically, philosophical investigation of what human beings are proceeds robustly. Many thinkers contend that whatever we are has little to do with how we should behave. Yet, tampering with what the human being is may tread upon human rights to be whatever one is. Rights given in widely recognized documents such as the U.N. Declaration of the Rights of Indigenous Peoples assume what humans are and need depends (...) upon ontological assumptions about human existence. Godman turns to human ontology—just what kind of beings humans are (from an angle distinct from the other two books) and how these play into rights. She is concerned with how well the social sciences accord with what we are. Gunkel homes in on a more specific moral topic than Godman's general concern with identity’s role in rights: automata moral status and rights. He enjoins us to inquire into what human rights are before we take on the new technologies’ challenge to it. Schneider’s Artificial You, while not explicitly about rights, poses a rights quandary. Certain individuals with reputable resources and practical backing explicitly seek to evolve the species as they see fit. The urgency among these works concerns how we need a sharper idea of what we are, how we should act and be treated, and how our rights fare among potential human improvements. (shrink)

The method of reflective equilibrium (MRE) is a method of justification popularized by John Rawls and further developed by Norman Daniels, Michael DePaul, Folke Tersman, and Catherine Z. Elgin, among others. The basic idea is that epistemic agents have justified beliefs if they have succeeded in forming their beliefs into a harmonious system of beliefs which they reflectively judge to be the most plausible. Despite the common reference to MRE as a method, its mechanisms or rules are typically expressed in (...) a metaphorical or simplified manner and are therefore criticized as too vague. Recent efforts to counter this criticism have been directed towards the attempt to provide formal explications of MRE. This paper aims to supplement these efforts by providing an informal working definition of MRE. This approach challenges the view that MRE can adequately be characterized only in the negative as a set of anti-essentialisms. I argue that epistemic agents follow MRE iff they follow four interconnected rules, which are concerned with a minimalistic form of foundationalism, a minimalistic form of fallibilism, a moderate form of holism, and a minimalistic form of rationality. In the critical spirit of MRE, the corresponding working definition is, of course, provisional and revisable. In general, the aim is to contribute to a reflective equilibrium (RE) concerning MRE. If it is successful, this working definition provides a better grasp of the most basic elements of the method and thereby enhances our understanding of it. (shrink)

This narrative commentary on Nietzschean ambitions, in part influenced by Zarathustra and Ecce Homo, centers on a long, ongoing, expansive, and highly imaginative technological projects by two men, Stuart Beholt and Alby Tolby. Having worked up adventurous software in university days, their experiences interwoven with their friendship bring out a panoply of current philosophical issues--and beyond. This narrative philosophy evokes and explores more issues than current philosophical debates concerning emerging technologies can include in a more conventional work. At the same (...) time, this structure makes the read readily accessible , including such issues as the intriguing recent flirtation of religion and materialism that have only been broached in the literature. At the same time, high finance and monetary issues, besides the alluring beauty of solving tremendous engineering problems, pull the two übermensch into ever greater schemes, well evoking the question of the limits of ethics and epistemology. Even if this approach does not coincide with the reader's research, it can offer an enjoyable delving into philosophical problems. (shrink)

This philosophical narrative delves into deepening crises afflicting modern democracies, when extreme inequality and its resultant alienation grips not just adults but, even more anguishingly, children. These children and often their parents come in far under the social radar, so out-of-touch that even census takers overlook them. In this milieu, weapons and narcotics are as much an unquestioned part of life as breathing. The world beyond this invisible cage entirely escapes them, nor does the larger society miss them or know (...) about them. This documentary narrative follows a thirteen-year-old who forces himself to escape his oblivious father, not out of hope, but for sheer escape from the execrable situation, without even the will to be himself, whatever that is. He also must navigate through his nightmare existemce, relying on an illicit business, the only thing he knows as well as breathing. If the individuals in this milieu--which cut across racial boundaries--ever even hear of voting, they are drawn to strong-arm politicians, who appeal to these scattered inhabitants, as examples of strength, no-nonsense, even hatred. The ethics of such circumstances' mere existence--further extreme than even those in Les Miserable--in our societies poses a formidable challenge to the ethics of social and political philosophy and are hardly touched upon in the academic literature. The central philosophical question is whether it is possible for a political system to preempt such conditions, particularly when these individuals, especially the children, are veritably invisible. The metaphilosophical issue is why philosophy does not focus more concern about this ignored human morass. To say an indictment of soiciopolitical philosophy is not justified here, that the persons encountered here are merely messed-up self-indulgent people, only adds cause to the charge. (shrink)

While more species are being identified as cultural on a regular basis, stark differences between human and animal cultures remain. Humans are more richly cultural, with group-specific practices and social norms guiding almost every element of our lives. Furthermore, human culture is seen as cumulative, cooperative, and normative, in contrast to animal cultures. One hypothesis to explain these differences is grounded in the observation that human children across cultures appear to spontaneously over-imitate silly or causally irrelevant behaviors that they observe. (...) The few studies on over-imitation in other species are largely taken as evidence that spontaneous over-imitation is not present in other species. This leads to the over-imitation hypothesis – that the differences between human culture and animal cultures can be traced to the human unique tendency to over-imitate. In this paper, we analyze the current state of the literature on animal over-imitation and challenge the adequacy of the over-imitation hypothesis for the differences between humans and animal cultures. To make this argument, we first argue that the function of human over-imitation is norm-learning and that over-imitation, like skill-learning, should be subject to selective social learning effects. Then we review the empirical evidence against animal over-imitation and argue that these studies do not take into account the relevant variables given the normative and selective nature of over-imitation. We then analyze positive empirical evidence of over-imitation in great apes and canids from the experimental literature and conclude that the current body of evidence suggests that some canids and primates may have the capacity for over-imitation. This paper offers a methodological suggestion for how to study animal over-imitation, and a theoretical suggestion that over-imitation might be much more widely found among species. The larger implication for claims about human uniqueness suggests that if we do find widespread evidence of over-imitation across species, many of the current theories of human uniqueness that focus on human hyper-cooperation or social norms may have only identified a difference of degree, not of kind, between humans and other animals.

In terms of validity in Kripke frames, a modal formula expresses a universal monadic second-order condition. Those modal formulae which are equivalent to first-order conditions are called elementary. Modal formulae which have a certain persistence property which implies their validity in all canonical frames of modal logics axiomatized with them, and therefore their completeness, are called canonical. This is a survey of a recent and ongoing study of the class of elementary and canonical modal formulae. We summarize main ideas and (...) results, and outline further research perspectives. (shrink)

In the world of philosophy of science, the dominant theory of confirmation is Bayesian. In the wider philosophical world, the idea of inference to the best explanation exerts a considerable influence. Here we place the two worlds in collision, using Bayesian confirmation theory to argue that explanatoriness is evidentially irrelevant.

As automating technologies are increasingly integrated into workplaces, one concern is that many of the human workers who remain will be relegated to more dull and less positively impactful work. This paper considers two rival theories of meaningful work that might be used to evaluate particular implementations of automation. The first is achievementism, which says that work that culminates in achievements to workers’ credit is especially meaningful; the other is the practice view, which says that work that takes the form (...) of an open-ended practice is especially meaningful. Of the two, the practice view is the better tool for assessing the future of meaningful work, because achievementism is explanatorily inadequate in two ways. Moreover, the practice view can explain why the most meaningful forms of work cannot be automated. A procedure can only be automated as long as the steps are defined, whereas, in such work, which steps to take is indefinitely open to redefinition. This reveals the real threat to meaningful work to be a political-economic one. The relevant ethical questions there have to do with how much creative control workers retain in crafting their own jobs, when those jobs involve meaningful work in collaboration with machines; and how to liberate workers from jobs that do not involve meaningful work, which should be left to machines anyway.

Ausgangspunkt ist die Frage, was Masse ist, wodurch sie insbesondere befähigt ist, Dauer zu konstituieren und deshalb - im Sinn des kinematischen Relativitätsprinzips - ebenso als bewegt wie als ruhend betrachtet werden kann. In einem Gedankenexperiment wird diese Frage, in Umkehrung der Perspektive, hier nicht von der Masse selbst, sondern von einer stehenden Lichtwelle her angegangen. In diesem Modell lassen sich masse-analoge Strukturen rekonstruieren, die in relativer Bewegung sein können. Die (empirisch bekannte) Unabhängigkeit der Lichtgeschwindigkeit vom Bezugssystem ist dabei nicht (...) vorausgesetzt. Doch kann gezeigt werden, dass die Lichtgeschwindigkeit Grenzgeschwindigkeit solcher relativer Bewegungen ist, dass dies für alle durch masse-analoge Strukturen konstituierte, relativ zueinander gleichförmig bewegten Bezugssysteme gilt und dass die Lichtgeschwindigkeit selbst in allen diesen Systemen gleich ist. Die Absolutheit der Lichtgeschwindigkeit und die Relativität der Massebewegungen erweisen sich so als zwar differente, aber intrinsisch zusammengehörende Momente des kinematischen Relativitätsprinzips: ein Beitrag zu einer Philosophie der Relativitätstheorie. - Die mathematischen Zusammenhänge werden im Anhang ausführlicher dargelegt.

How do brains create all our different colors, pains, and other conscious qualities? These various qualia are the most essential aspects of consciousness. Yet standard neuroscience (primarily based on synaptic information processing) has not found the synaptic-firing codes, sometimes described as the “spike code,” to account for how these qualia arise and how they unite to form complex perceptions, emotions, et cetera. Nor is it clear how to get from these abstract codes to the qualia we experience. But electromagnetic field (...) (versus synaptic) approaches to how qualia arise have been offered in recent years by Pockett, McFadden, Jones, Bond, Ward and Guevera, Keppler and Shani, Hunt and Schooler, et cetera. These EM-field approaches show promise in offering more viable accounts of qualia. Yet, until now, they have not been evaluated together. We review various EM field theories of qualia, highlight their strengths and weaknesses, and contrast these theories with standard neuroscience approaches. -/- . (shrink)

The nature-nurture debate rages so, one cannot help but wonder why the sides are so vehemently partitioned. What's at stake? It is simply not clear why a great amount of people embrace either one side or the other, but dare not even blow a kiss to the opposite opinion. Prinz does an excellent job of arguing for the nurture position, zeroing in on some of the most preciously held nature arguments including the basis of knowledge, thought, and feelings in experience (...) and cultural values, increasing as a child grows. Most prominent of the nature hypothèses that Prinz takes on may be that of language acquisition and the Chomskyean notion of inborn lingusitic knowledge, via the proposed universal language. He contends that children's language acquisition--even the notion that the supposed inborn language device shuts off somewhere in mid-childhood, meaning most people will not be fully bilingual--need not demand such a natural language faculty in the brain, as general learning strategies can account for language acquisition. His arguments can stimulate both nurturists and naturists. Yet, in the end--realizing how much of the human arise from the genes--one still cannot help wonder why the two debated positions so rally to one flag or the other. (shrink)

In the last two decades we have witnessed considerable efforts directed towards making electronic healthcare records comparable and interoperable through advances in record architectures and (bio)medical terminologies and coding systems. Deep semantic issues in general, and ontology in particular, have received some interest from the research communities. However, with the exception of work on so-called ‘controlled vocabularies’, ontology has thus far played little role in work on standardization. The prime focus has been rather the rapid population of terminologies at the (...) level of fine detail. In this paper, we argue that more efforts are needed on the side of both research and standardization to ensure that the coding systems used in electronic healthcare records enjoy a semantics that is coherent with the semantics of the record. We propose realist ontology as a method to bring about this coherence by means of a robust system of top-level ontological categories. (shrink)

Nudging works through dispositions to decide with specific heuristics, and has three component parts. A nudge is a feature of an environment that enables such a disposition; a person is nudged when such a disposition is triggered; and a person performs a nudged action when such a disposition manifests in action. This analysis clarifies an autonomy-based worry about nudging as used in public policy or for private profit: that a person’s ability to reason well is undermined when she is nudged. (...) Reasoning well is a component of self-guidance, which is an aspect of autonomy and so something there is reason to promote, preserve, or respect. However, a person can reason well when she is nudged: Many of these heuristics are good rules to reason with, and she can be flexible with respect to them when she takes there to be a better way to reason. Along the way, this paper uncovers several design specifications for responsible nudging, and discusses open empirical questions. However, nudging’s being compatible with reasoning well crystallizes a distinct worry about manipulation: that nudge designers can rely on nudged people guiding themselves toward the designers’ own ends. Manipulation of this sort exploits one aspect of autonomy (namely, self-guidance) to undermine autonomy in other respects. (shrink)

I offer a line of argument that aims at the conclusion that the notion of radically different and incommensurable systems of value is incoherent, which would mean that the presumption of some significant common ground of valuation is rationally required in value inquiry.

Amalia Holst was an important pedagogical theorist and philosopher who was part of the distinctive intellectual milieu of Hamburg in the late 18th and early 19th century. Holst has enjoyed a fair amount of attention from scholars working on the history of feminism, and she has recently come to the attention of historians of philosophy for her incisive critique of (Rousseau-inspired) educational theories, her vocal advocacy for women’s access to higher education, and for apparently radical lines of thinking in her (...) views on history, religion, and morality. While Holst was something of a public figure in Hamburg—she published two controversial treatises in her lifetime, in addition to a lengthy review of a popular novel—there is relatively little known about her life, with most of what we do know owed to only a sparse handful of sources. It is, therefore, a rather significant development for scholars working on Holst that two letters by her should come to light. These letters are replete with new details of Holst’s life, her intellectual network, and they seem to have been wholly unaccounted for by Holst’s biographers. In this article, I will provide a transcription and translation, with annotations, of the two new letters. (shrink)

The Swiss psychologist Jean Piaget contends that children below the age of 12 see no necessity for the logical law of non-contradiction. I argue this view is problematic. First of all, Piaget's dialogues with children which are considered supportive of this position are not clearly so. Secondly, Piaget underestimates the necessary nature of following the logical law of non-contradiction in everyday discourse. The mere possibility of saying something significant and informative at all presupposes that the law of non-contradiction is enforced.

This paper details how ghost hunting, as a set of learning activities, can be used to enhance critical thinking and philosophy of science classes. We describe in some detail our own work with ghost hunting, and reflect on both intended and unintended consequences of this pedagogical choice. This choice was partly motivated by students’ lack of familiarity with science and philosophic questions about it. We offer reflections on our three different implementations of the ghost hunting activities. In addition, we discuss (...) the practical nuances of implementing these activities, as well the relation of ghost hunting to our course content, including informal fallacies and some models for scientific inference. We conclude that employing ghost hunting along-side traditional activities and content of critical thinking and philosophy of science offers a number of benefits, including being fun, increasing student attendance, enhancing student learning, and providing a platform for campus wide dialogues about philosophy.

Russellian monism (RM) attributes experience to the intrinsic nature of physics’ abstract mathematical accounts of the world. It’s touted as a promising mind-body solution, for it avoids dualist and physicalist issues. Yet this status is imperiled by its deeply obscure ideas of mental combination, protophenomenal entities, emergent experience, grounded abstractions, et cetera. This “metaphysical magical mystery tour” may render RM as problematic as competing views. A clear, simple panpsychism akin to Strawson’s might avoid these issues. In this theory (NPP), experience (...) is the real, underlying nature of matter-energy, hidden beyond its sensory appearances. NPP may avoid panpsychist combination problems by showing how neurons can electrically bind their minimal experience to form percepts, thoughts, and subjects. This might explain combination in testable ways, while RM instead turns to questionable microsubjects and binding mechanisms. NPP’s virtues are its metaphysical simplicity, empirical support, testable foundations—and its avoidance of the issues in RM and other standard theories. It might point to a mind-body solution.

Maximalism is the view that an agent is permitted to perform a certain type of action if and only if she is permitted to perform some instance of this type, where φ-ing is an instance of ψ-ing if and only if φ-ing entails ψ-ing but not vice versa. Now, the aim of this paper is not to defend maximalism, but to defend a certain account of our options that when combined with maximalism results in a theory that accommodates the idea (...) that a moral theory ought to be morally harmonious—that is, ought to be such that the agents who satisfy the theory, whoever and however numerous they may be, are guaranteed to produce the morally best world that they have the option of producing. I argue that, for something to count as an option for an agent, it must, in the relevant sense, be under her control. And I argue that the relevant sort of control is the sort that we exercise over our reasons-responsive attitudes by being both receptive and reactive to reasons. I call this sort of control rational control, and I call the view that φ-ing is an option for a subject if and only if she has rational control over whether she φs rationalism. When we combine this view with maximalism, we get rationalist maximalism, which I argue is a promising moral theory. (shrink)
