Nearly all research in neurofeedback since the 1960s has focused on training voluntary control over EEG constructs. By contrast, EEG state discrimination training focuses on awareness of subjective correlates of EEG states. This study presents the first successful replication of EEG alpha state discrimination first reported by Kamiya . A 150-s baseline was recorded in 106 participants. During the task, low triggered a prompt. Participants indicated “high” or “low” with a keypress response and received immediate feedback. Seventy-five percent of participants (...) achieved significant discrimination within nine sessions, with a significant learning curve effect. Performance was significantly related to physical properties of the EEG signal, including magnitude, duration, and absolute vs. relative amplitude. These results are consistent with a conceptualization of EEG state discrimination as a sensory modality, although it is also intricately related to voluntary control of these states. (shrink)

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

This paper involves one crucial assumption; namely, that the statistical predictions of quantum mechanics for Bell's variant of the EPR experiment will continue to be verified as detector efficiencies are improved and the need for coincidence counters is eliminated. This assumption entails that any hidden-variables theory for quantum mechanics must violate Bell's inequality--the inequality derived in Bell (1964). It is shown here that four locality conditions are involved in the derivation of Bell's inequality; and that a violation of any of (...) the four locality conditions will either entail the existence of superluminal influences or the existence of superluminal signals (superluminal influences that can be used to transmit information), if conspiratorial theories can be ruled out. The attempts so far to rule out conspiratorial theories are all found to be rather dubious, but there are other considerations developed here that rule them out convincingly. Finally, it is demonstrated that violations of each of the four locality conditions can be used to transmit information superluminally, if certain auxiliary conditions are satisfied. This is of particular interest because one of these conditions corresponds to a condition dubbed "completeness" by Jon Jarrett. Jarrett and others have suggested that violations of completeness cannot be used to send information superluminally. Demonstrating otherwise is, perhaps, the most significant result obtained in this paper. (shrink)

Scholars find that political elites are badly polarized over a large range of policy issues, but they tend to agree that the mass public is much more ambivalent. The abortion war in particular is regarded as one in which millions of ambivalent citizens are caught in the crossfire of polarized activists. Yet even abortion activists struggle to escape the very ambivalent sentiments that plague ordinary Americans. These common sentiments even exert a moderating influence on both movements in ways that are (...) consistent with the preferences of the American public. They also suggest that liberalism may be mired in permanent conflict and ambivalence over the scope of basic human rights. (shrink)

No articulation of `historical thinking' has been as influential as Sam Wineburg's position, according to which historical thinking is, fundamentally, the recognition of the ways in which the past is different than the present. Wineburg argues, further, that achieving that state is `unnatural.' This paper critiques both of these claims, arguing instead that we should replace a generic conception of historical thinking with one that is much more rooted in the specific practice of the discipline. It is surely necessary for (...) students to learn this practice, but it is not unnatural. Instead, learning to think historically is learning to speak the language of the discipline that we call ‘history.’. (shrink)

MORE THAN MOST PHILOSOPHERS, Spinoza needed a coherent and sophisticated set of views on the nature of possibility: many of his most important philosophical positions and arguments depended on it. As one example, take Ethics IP33. This Proposition—among the most famous of the Ethics— states, “Things could have been produced by God in no other way, and in no other order than they have been produced.” In a salutary attempt to clarify the meaning of IP33 et relata, Spinoza adds in (...) the first Scholium to IP33 that “by these propositions I have shown more clearly than the noon light that there is absolutely nothing in things on account of which they can be called contingent.” Now, such assertions were bound to give rise to numerous objections and Spinoza knew it. To meet these objections, he immediately proceeds to one of the most powerful: namely, are there not things that actually have been “produced by God” that need not have been “produced by God?” And would it not make sense to call these things “contingent or possible?” In reply, Spinoza reinterprets the concept of possibility. We call existing things “contingent” “only because of a defect of our knowledge.” There are, he continues, two types of deficiency that lead us to regard existing things as “contingent or possible”: either we do not know “that the thing’s essence involves a contradiction” or we do know that the thing’s essence does not involve a contradiction but we do not know enough about the “order of causes” to affirm anything “certainly about its existence.”.

ABSTRACT The media's attentive vigil over America's most militant and outrageous activists in the abortion wars has obscured a massive but quiet effort on the part of evangelicals to engage their opponents in exemplary deliberative discussions about bioethics. For a variety of reasons, activists in the pro‐life movement are more committed to carving out civic spaces for such dialogue than are their pro‐choice counterparts. This discrepancy invites investigation into the forces that promote and constrain political movements' interest in deliberation, as (...) well as highlighting the undeniable limits to deliberative ideals.

The cumulative impact of enhancement technologies may alter the human species in the very long-term future. In this article, I will start showing how radical genetic enhancements may accelerate the conversion into a novel species. I will also clarify the concepts of ‘biological species’, ‘transhuman’ and ‘posthuman’. Then, I will summarize some ethical arguments for creating a transhuman or posthuman species with a substantially higher level of well-being than the human one. In particular, I will present what I shall call (...) the Principle of the Best Interests of Posthumanity, which states that the enhancement of the human and transhuman species must be directed towards the creation of a posthuman existence that is substantially more valuable than its predecessors. I suggest that human extinction may be considered, within that principle, as one of the best interests of posthumanity. Finally, I will develop three objections that make that principle unattractive and that show that pursuing a full-blown programme of posthuman evolution is ethically flawed. (shrink)

A critique of the hypothesis of extended cognition.

Social roles theorists claim that differences between the sexes are of limited consequence. Such misperceptions lead to misunderstanding the important role of sexual selection in explaining phenotypic differences both between species and within humans. Countering these claims, we explain how sexual dimorphism in humans affect expressions of artistic display and patterns of male and female aggression across the ovulatory cycle.

Historians typically tell stories about the past, but how are we to understand the epistemic status of those narratives? This problem is particularly pressing for history education, which seeks guidance not only on the question of which narrative to teach but also more fundamentally on the question of the goals of instruction in history. This article explores the nature of historical narrative, first, by engaging with the seminal work of Hayden White, and second, by developing the critique of White by (...) David Carr. The picture of historical inquiry that emerges is one in which the fundamental cognitive activity is one of negotiating among narratives. Students, like historians, like any of us, come to the work of historical inquiry in possession of prior narratives, which are then thrown into an encounter with other narratives of varying size and scope. Good historians enact the negotiation among narratives responsibly and well, demonstrating the virtues of historical interpretation. History education, therefore, ought to help students improve their historical interpretations at the same time as it fosters those qualities that make them good interpreters. (shrink)

This paper takes up and provides three answers to the question “Why study philosophy?” Beginning with a discussion of why this question has been ignored in literature pertaining to the teaching of philosophy, the paper turns to an analysis of what it means to ask about the importance of philosophy, pointing out that the question is ambiguous with other questions like “why should so-and-so study philosophy” or “why does so-and-so study philosophy.” The author then provides three answers that are similar (...) to those provided by Hume: one should study philosophy because it may contribute to the entertainment, instruction, and reformation of mankind. The paper argues for the superiority of these answers over traditional responses and points to the importance of this question in teaching philosophy. (shrink)

Talisse and Maloney seem to think that professors, not ordinary citizens, are the key to a more deliberative democracy. Yet these professors fail to appreciate the reasonableness of the pro‐life activists and thinkers they disagree with. For example, they falsely charge even the most deliberative groups with resurrecting an obsolete debate and framing conversations in a fallacious way. They further place an unreasonable justificatory burden on pro‐life activists and hold them culpable for framing the debate around the ontology of the (...) embryo . In drawing such a hard line between academics and activists, they also miss what has been an unavoidable partnership between academics and social movements in our imperfect deliberative republic.

Objective Bayesianism is a methodological theory that is currently applied in statistics, philosophy, artificial intelligence, physics and other sciences. This book develops the formal and philosophical foundations of the theory, at a level accessible to a graduate student with some familiarity with mathematical notation.

Bringing together powerful new tools from set theory and the philosophy of language, this book proposes a solution to one of the few unresolved paradoxes from antiquity, the Paradox of the Liar. Treating truth as a property of propositions, not sentences, the authors model two distinct conceptions of propositions: one based on the standard notion used by Bertrand Russell, among others, and the other based on J.L. Austin's work on truth. Comparing these two accounts, the authors show that while the (...) Russellian conception of the relation between sentences, propositions, and truth is crucially flawed in limiting cases, the Austinian perspective has fruitful applications to the analysis of semantic paradox. In the course of their study of a language admitting circular reference and containing its own truth predicate, Barwise and Etchemendy also develop a wide range of model-theoretic techniques--based on a new set-theoretic tool, Peter Aczel's theory of hypersets--that open up new avenues in logical and formal semantics.

Critics of attention-deficit/hyperactivity disorder (ADHD) have repeatedly argued that there is no proof for the condition being symptomatic of an organic brain disease and that the current "ADHD epidemic" is an expression of medicalization. To this, the supporters of ADHD can retort that the condition is only defined as a mental disorder and not a physical disease. As such, ADHD needs only be a harmful mental dysfunction, which, like other genuine disorders, can have a complex and obscure etiology. This article (...) argues that such a line of argument fails to save ADHD as a valid diagnostic category. Given the general diagnostic logic of the DSM-IV and how ADHD has been defined in terms of everyday (male) child behaviors, there are compelling grounds to disbelieve that ADHD can be a true medical syndrome united by some type of harmful dysfunction. Indeed, strong logical and empirical reasons will be adduced to show that people may qualify for ADHD diagnosis without suffering from any type of underlying pathology. (shrink)

According to the ‘fact-plus-value’ model of pathology propounded by K. W. M. Fulford, ‘disease’ is a value term that ought to reflect a ‘balance of values’ stemming from patients and doctors and other ‘stakeholders’ in medical nosology. In the present article I take issue with his linguistic-analytical arguments for why pathological status must be relative to such a kind of medico-ethical normativity. Fulford is right to point out that Boorse and other naturalists are compelled to utilize evaluative terminology when they (...) characterize the nature of diseases and biological dysfunctions. But the relevant ‘biofunctional judgements’ are no less factual and empirical for that. While it is indeed evaluative to say that biological dysfunctions involve failures to execute naturally selected functions, such judgments are not bound to entail anything about what is good or bad for us, and what should be treated or not. In the last part of the paper I ruminate briefly on the relationship between ‘biological evaluationism’, on my construal, and descriptions of ‘causal biology’. As I note in my conclusion, a strict bioevaluative concept of disease can be valid for every species on earth, and thus be of particular usefulness in general biological contexts. (shrink)

Hyperproof is a system for learning the principles of analytical reasoning and proof construction, consisting of a text and a Macintosh software program. Unlike traditional treatments of first-order logic, Hyperproof combines graphical and sentential information, presenting a set of logical rules for integrating these different forms of information. This strategy allows students to focus on the information content of proofs, rather than the syntactic structure of sentences. Using Hyperproof the student learns to construct proofs of both consequence and nonconsequence using (...) an intuitive proof system that extends the standard set of sentential rules to incorporate information represented graphically. Hyperproof is compatible with various natural-deduction-style proof systems, including the system used in the authors' Language of First-Order Logic. (shrink)

Bayesian nets are widely used in artificial intelligence as a calculus for causal reasoning, enabling machines to make predictions, perform diagnoses, take decisions and even to discover causal relationships. This book, aimed at researchers and graduate students in computer science, mathematics and philosophy, brings together two important research topics: how to automate reasoning in artificial intelligence, and the nature of causality and probability in philosophy.

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly phenomenon (...) whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

Hegel is one of the major philosophers of the nineteenth century. Many of the major philosophical movements of the twentieth century - from existentialism to analytic philosophy - grew out of reactions against Hegel. He is also one of the hardest philosophers to understand and his complex ideas, though rewarding, are often misunderstood. In this magisterial and lucid introduction, Frederick Beiser covers every major aspect of Hegel's thought. He places Hegel in the historical context of nineteenth-century Germany whilst clarifying (...) the deep insights and originality of Hegel's philosophy. A masterpiece of clarity and scholarship, _Hegel_ is both the ideal starting point for those coming to Hegel for the first time and essential reading for any student or scholar of nineteenth century philosophy. Additional features: glossary chapter summaries chronology annotated further reading. (shrink)

Weltschmerz is a study of the pessimism that dominated German philosophy in the second half of the nineteenth century. Pessimism was essentially the theory that life is not worth living, and was introduced into German philosophy by Schopenhauer. Frederick C. Beiser examines the intense and long controversy that arose from Schopenhauer's pessimism, which changed the agenda of philosophy in Germany away from the logic of the sciences and toward an examination of the value of life. He examines the major (...) defenders of pessimism and its chief critics, especially Eugen Dühring and the neo-Kantians. The pessimism dispute of the second half of the century has been largely ignored in secondary literature and this book is a first attempt since the 1880s to re-examine it and to analyze the important philosophical issues raised by it. The dispute concerned the most fundamental philosophical issue of them all: whether life is worth living. (shrink)

ABSTRACT Donald Trump’s victory depended on the defection of hundreds of longstanding Democratic communities. Trump appealed to these communities partly because he behaves like some of their most beloved politicians. Like the president, these politicians are brazen, thin skinned, nepotistic, and offer an older, boss-centered vision of politics. Trump—the anti-establishment outsider—appealed to voters in these communities because he resembles the local insiders. This appeal widens an old fault line inside the Democratic Party.

The claim that corporations are not people is perhaps the most frequently voiced criticism of the United States Supreme Court decision Citizens United v. Federal Election Commission. There is something obviously correct about this claim. While the nature and extent of obligations with respect to group agents like corporations and labor unions is far from clear, it is manifest in moral understanding and deeply embedded in legal practice that there is no general requirement to treat them like natural persons. Group (...) agents may be denied rights to marry, vote, or run for public office. More generally the need to guard against discrimination, the core injustice in racism and sexism, has no direct application to the case of group agents. There is also something obviously incorrect about the claim that corporations are not people. The legal practice of treating some group agents as persons under law is ancient, found already in Roman law at the time of Justinian. In this essay I propose that reflection on this tension reveals that fundamental revision to the doctrine of legal personhood is needed. More specifically I propose that legal personhood be decomposed into at least two elements—standing and liability—and that legal systems reject the principle that an entity possesses one just in case it possesses the other. The import of this change ramifies broadly. Decomposing legal personhood not only enables a satisfactory account of the status of corporations and labor unions, who as such have liability but not standing, it also enables a satisfactory account of the status of those who as such have standing but not liability: severely mentally disabled persons, very young children, and non-human animals with phenomenal consciousness but lacking capacities to understand reasons and justifications.

The Human Sciences after the Decade of the Brain brings together exciting new works that address today’s key challenges for a mutual interaction between cognitive neuroscience and the social sciences and humanities. Taking up the methodological and conceptual problems of choosing a neuroscience approach to disciplines such as philosophy, history, ethics and education, the book deepens discussions on a range of epistemological, historical, and sociological questions about the "neuro-turn" in the new millennium. The book’s three sections focus on (i) epistemological (...) questions posed by neurobiologically informed approaches to philosophy and history, (ii) neuroscience’s influence on explanations for social and moral behavior, and (iii) the consequences of the neuro-turn in diverse sectors of social life such as science, education, film, and human self-understanding. This book is an important resource both for students and scholars of cognitive neuroscience and biological psychology interested in the philosophical, ethical, and societal influences of—and on—their work as well as for students and scholars from the social sciences and humanities interested in neuroscience.

While there are several arguments on either side, it is far from clear as to whether or not countable additivity is an acceptable axiom of subjective probability. I focus here on de Finetti's central argument against countable additivity and provide a new Dutch book proof of the principle, To argue that if we accept the Dutch book foundations of subjective probability, countable additivity is an unavoidable constraint.

We discuss external and internal graphical and linguistic representational systems. We argue that a cognitive theory of peoples' reasoning performance must account for (a) the logical equivalence of inferences expressed in graphical and linguistic form, and (b) the implementational differences that affect facility of inference. Our theory proposes that graphical representation limit abstraction and thereby aid “processibility”. We discuss the ideas of specificity and abstraction, and their cognitive relevance. Empirical support both comes from tasks which involve the manipulation of external (...) graphics and tasks that do not. For the former, we take Euler's (1772) circles, provide a novel computational reconstruction, show how it captures abstractions, and contrast it with earlier construals and with Johnson‐Laird's (1983) mental models representations. We demonstrate equivalence of the graphical Euler system, and the nongraphical mental models system. For tasks not involving manipulation of external graphics, we discuss text comprehension, and the mental performance of syllogisms. By positing an internal system with the same specificity as Euler's circles, we cover the mental models data, and generate new empirical predictions. Finally, we consider how the architecture of working memory explains why such specific representations are relatively easy to store. (shrink)

Histories of German philosophy in the nineteenth century typically focus on its first half--when Hegel, idealism, and Romanticism dominated. By contrast, the remainder of the century, after Hegel's death, has been relatively neglected because it has been seen as a period of stagnation and decline. But Frederick Beiser argues that the second half of the century was in fact one of the most revolutionary periods in modern philosophy because the nature of philosophy itself was up for grabs and the (...) very absence of certainty led to creativity and the start of a new era. In this innovative concise history of German philosophy from 1840 to 1900, Beiser focuses not on themes or individual thinkers but rather on the period's five great debates: the identity crisis of philosophy, the materialism controversy, the methods and limits of history, the pessimism controversy, and the Ignorabimusstreit. Schopenhauer and Wilhelm Dilthey play important roles in these controversies but so do many neglected figures, including Ludwig Büchner, Eugen Dühring, Eduard von Hartmann, Julius Fraunstaedt, Hermann Lotze, Adolf Trendelenburg, and two women, Agnes Taubert and Olga Pluemacher, who have been completely forgotten in histories of philosophy. The result is a wide-ranging, original, and surprising new account of German philosophy in the critical period between Hegel and the twentieth century. (shrink)

Alvin Plantinga has famously responded to the logical problem of evil by appealing to the intrinsic value of significant free will. A problem, however, arises because traditional theists believe that both God and the redeemed who go to heaven cannot do wrong acts. This entails that both God and the redeemed in heaven lack significant freedom. If significant freedom is indeed valuable, then God and the redeemed in heaven would lack something intrinsically valuable. However, if significant freedom is not intrinsically (...) valuable, then Plantinga’s reply to the logical problem of evil fails. In this paper, we assess three contemporary solutions to the dilemma above. The first is the love solution, which proposes that significant freedom is necessary for agents to love, and loving others is intrinsically good. The second is the soul-making solution, which argues that significant freedom is necessary for self-developing one’s moral character, and having a self-developed moral character is intrinsically good. The third is the derivative free will solution, which argues that significant freedom is necessary for derivative free will in heaven, and derivative free will is intrinsically good. We raise problems against all three solutions and instead defend a fourth solution – the ultimate responsibility solution. That is, significant freedom is instrumentally valuable as it gives agents ultimate responsibility with regards to morally significant acts. Finally, we defend the ultimate responsibility solution against two major objections. (shrink)

Del Giudice addresses a complex and pertinent theoretical issue: the evolutionary adaptiveness of sex differences in attachment styles in relation to life history strategy. Although we applaud Del Giudice for calling attention to the problem, we regret that he does not sufficiently specify how attachment styles serve as an integral part of a coordinate life history strategy for either sex.
