GraphicalThirty healthy participants received 60 trials of intermittent SO tACS at an intensity of 2 mA. Motor cortical excitability was assessed using TMS-induced MEPs acquired across different oscillatory phases during and outlasting tACS, as well as at the start and end of the stimulation session. Mean MEP amplitude increased by ∼41% from pre- to post-tACS ; however, MEP amplitudes were not modulated with respect to the tACS phase.Converging evidence suggests that transcranial alternating current stimulation may entrain endogenous neural oscillations to (...) match the frequency and phase of the exogenously applied current and this entrainment may outlast the stimulation. However, observing entrainment in the electroencephalograph during stimulation is extremely difficult due to the presence of complex tACS artifacts. The present study assessed entrainment to slow oscillatory tACS by measuring motor cortical excitability across different oscillatory phases during and outlasting stimulation. 30 healthy participants received 60 trials of intermittent SO tACS at an intensity of 2 mA peak-to-peak. Motor cortical excitability was assessed using transcranial magnetic stimulation of the hand region of the primary motor cortex to induce motor evoked potentials in the contralateral thumb. MEPs were acquired at four time-points within each trial – early online, late online, early offline, and late offline – as well as at the start and end of the overall stimulation period. A significant increase in MEP amplitude was observed from pre- to post-tACS and from the first to the last tACS block. However, no phase-dependent modulation of excitability was observed. Therefore, although SO tACS had a facilitatory effect on motor cortical excitability that outlasted stimulation, there was no evidence supporting entrainment of endogenous oscillations as the underlying mechanism.

The increasingly lively controversy over scientific realism has become one of the principal themes of recent philosophy. 1 In watching this controversy unfold in the rather technical way currently in vogue, it has seemed to me that it would be useful to view these contemporary disputes against the background of such older epistemological issues as fallibilism, scepticism, relativism, and the traditional realism/idealism debate. This, then, is the object of the present book, which will recon sider the newer concerns about scientific (...) realism in the context of these older philosophical themes. Historically, realism concerns itself with the real existence of things that do not "meet the eye" - with suprasensible entities that lie beyond the reach of human perception. In medieval times, discussions about realism focused upon universals. Recognizing that there are physical objects such as cats and triangular objects and red tomatoes, the medievels debated whether such "abstract objects" as cathood and triangularity and redness also exist by way of having a reality indepen dent of the concretely real things that exhibit them. Three fundamen tally different positions were defended: (1) Nominalism. Abstracta have no independent existence as such: they only "exist" in and through the objects that exhibit them. Only particulars (individual substances) exist. Abstract "objects" are existents in name only, mere thought fictions by whose means we address concrete particular things. (2) Realism. Abstracta have an independent existence as such. (shrink)

This volume is about abstract objects and the ways we refer to them in natural language. Asher develops a semantical and metaphysical analysis of these entities in two stages. The first reflects the rich ontology of abstract objects necessitated by the forms of language in which we think and speak. A second level of analysis maps the ontology of natural language metaphysics onto a sparser domain--a more systematic realm of abstract objects that are fully analyzed. This second level reflects the (...) commitments of real metaphysics. The models for these commitments assign truth conditions to natural language discourse.

Contending that only a normative theory of rationality can be adequate to the complexities of the subject, this book explains and defends the view that rationality consists of the intelligent pursuit of appropriate objectives. Rescher considers the mechanics, rationale, and rewards of reason, and argues that social scientists who want to present a theory of rationality while avoiding the vexing complexities of normative deliberations must amend their perspective of the rational enterprise.

In mainstream analytic epistemology, Reformed theology has made its presence prominently felt in Reformed epistemology, the view of religious belief according to which religious beliefs can be properly basic and warranted when formed by the proper functioning of the sensus divinitatis, an inborn capacity or faculty for belief in God that can be prompted to generate certain religious beliefs when presented with things (e.g., certain majestic aspects of creation). A major competitor to Reformed epistemology is Wittgensteinian quasi-fideism, a position drawn (...) from the epistemology of Wittgenstein’s On Certainty, according to which some foundational religious commitments are not properly basic beliefs but some kind of apodictic, unshakeable certainties that form part of the structure of one’s rationality and worldview. I argue that the Reformed tradition has contained elements of quasi-fideism at least as far back as Calvin’s account of faith from the Institutes of the Christian Religion, book 3, chapter 2.

How can we think about things in the outside world? There is still no widely accepted theory of how mental representations get their meaning. In light of pioneering research, Nicholas Shea develops a naturalistic account of the nature of mental representation with a firm focus on the subpersonal representations that pervade the cognitive sciences.

Sandra Harding is working on the reconstruction of scientific objectivity. Lorraine Daston argues that objectivity is a concept that has historically evolved. Her account of the development of "aperspectival objectivity" provides an opportunity to see Harding's "strong objectivity" project as a stage in this evolution, to locate it in the history of migration of ideals from moral philosophy to natural science, and to support Harding's desire to retain something of the ontological significance of objectivity.

The uncanny is the weird, the strange, the mysterious, a mingling of the familiar and the unfamiliar. Even Freud, patron of the uncanny, had trouble defining it. Yet the uncanny is everywhere in contemporary culture. In this elegant book, Nicholas Royle takes the reader across literature, film, philosophy, and psychoanalysis as he marks the trace of the uncanny in the modern world. Not an introduction in the usual sense, Nicholas Royle's book is a geography of the uncanny as (...) it manifests itself - and disturbs our thinking - in a range of disciplines. (shrink)

A clearly written, authoritative introduction to Taylor's work.

Nicholas Rescher presents a critical reaction against two currently influential tendencies of thought. On the one hand, he rejects the facile relativism that pervades contemporary social and academic life. On the other hand, he opposes the rationalism inherent in neo-contractarian theory--both in the idealized communicative-contract version promoted in continental European political philosophy by J;urgen Habermas, and in the idealized social contract version of the theory of political justice promoted in the Anglo-American context by John Rawls. Against such tendencies, Rescher's (...) pluralist approach takes a more realistic and pragmatic line, eschewing the convenient recourse of idealization in cognitive and practical matters. Instead of a utopianism that looks to a uniquely perfect order that would prevail under ideal conditions, he advocates incremental improvements within the framework of arrangements that none of us will deem perfect but that all of us "can live with." Such an approach replaces the yearning for an unattainable consensus with the institution of pragmatic arrangements in which the community will acquiesce--not through agreeing on their optimality, but through a shared recognition among the dissonant parties that the available options are even worse.

Vice essentialism is the view that epistemic vices have robustly negative effects on our epistemic projects. Essentialists believe that the manifestation of epistemic vices can explain many of our epistemic failures, but few, if any, of our epistemic successes. The purpose of this paper is to argue that vice essentialism is false. In §1, I review the case that some epistemic vices, such as closed-mindedness and extreme epistemic deference, have considerably beneficial effects when manifested in collectivist contexts. In §2, I (...) add that there are putative epistemic vices whose repeated manifestation leads to significant epistemic achievements over time. Epistemic recklessness is one such unstable vice. Though Sosa argues that epistemically reckless judgements cannot constitute knowing full well, the repeated manifestation of epistemic recklessness is essential to our becoming fully well knowledgeable in the long run. Without making incompetent judgements in environments that offer unambiguous, actionable feedback, we could not develop the intuitive and reflective competences and meta-competences required for knowing full well.

How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows (...) us, as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature..."--Jacket. (shrink)

This chapter provides an introduction to higher-order metaphysics as well as to the contributions to this volume. We discuss five topics, corresponding to the five parts of this volume, and summarize the contributions to each part. First, we motivate the usefulness of higher-order quantification in metaphysics using a number of examples, and discuss the question of how such quantifiers should be interpreted. We provide a brief introduction to the most common forms of higher-order logics used in metaphysics, and indicate a (...) number of questions which can be raised in such systems using logical vocabulary alone. Using a further example, we return to applications of higher-order logics in metaphysics. We also mention key developments in the history of higher-order logic as it pertains to metaphysics. Finally, we mention certain arguments which have been raised against the use of higher-order logic, and some ways of responding to them. (shrink)

In this entertaining and provocative introduction, Royle offers lucid explanations of various key ideas, including deconstruction, undecidability, iterability, differance, aporia, the pharmakon, the supplement, a new enlightenment, and the democracy to come. He also gives attention, however, to a range of less obvious key ideas of Derrida, such as earthquakes, animals and animality, ghosts, monstrosity, the poematic, drugs, gifts, secrets, war, and mourning. Derrida is seen as an extraordinarily inventive thinker, as well as a brilliantly imaginative and often very funny (...) writer. Other critical introductions tend to highlight the specifically philosophical nature and genealogy of his work. Royle's book proceeds in a new and different way, in particular by focusing on the crucial but strange place of literature in Derrida's writings. He thus provides an appreciation and understanding based on detailed reference to Derrida's texts, interwoven with close readings of such writers as Shakespeare, Coleridge, P.B. Shelley, Poe, Emily Brontë, Franz Kafka and Elizabeth Bowen. In doing so, he explores Derrida's consistent view that deconstruction is "a coming-to-terms with literature". He emphasizes the ways in which "literature", for Derrida, is indissociably bound up with other concerns, such as philosophy and psychoanalysis, politics and ethics, responsibility and justice, law and democracy.

The concept of an "idea" played a central role in 17th-century theories of mind and knowledge, but philosophers were divided over the nature of ideas. This book examines an important, but little-known, debate on this question in the work of Leibniz, Malebranche, and Descartes. Looking closely at the issues involved, as well as the particular context in which the debate took place, Jolley demonstrates that the debate has serious implications for a number of major topics in 17th-century philosophy.

I take pseudoscience to be a pretence at science. Pretences are innumerable, limited only by our imagination and credulity. As Stove points out, ‘numerology is actually quite as different from astrology as astrology is from astronomy’ (Stove 1991, 187). We are sure that ‘something has gone appallingly wrong’ (Stove 1991, 180) and yet ‘thoughts…can go wrong in a multiplicity of ways, none of which anyone yet understands’ (Stove 1991, 190). Often all we can do is give a careful description of (...) a way of pretending, a motivation for pretence, a source of pretension. In this chapter I attempt the latter. We will be concerned with the relation of conviction to rational belief. I shall be suggesting that the question of whether an enquiry is a pretence at science can be, in part, a question over the role of conviction in rational belief, and that the answer is to be found in the philosophical problem of the role of values in rational belief.

This volume sets out to reverse the neglect.

: In the epistemology of the late Wittgenstein, a central place is given to the notion of the hinge: an arational commitment that provides a foundation of some sort for the rest of our beliefs. Quasi-fideism is an approach to the epistemology of religion that argues that religious belief is on an epistemic par with other sorts of belief inasmuch as religious and non-religious beliefs all rely on hinges. I consider in this paper what it takes to find the appropriate (...) hinge for a quasi-fideist approach to the epistemology of religion. (shrink)

We discuss the rational role of highly inattentive experiences, and argue that they can provide rational support for beliefs.

The aim of this paper is to provide a detailed characterisation of some ways in which our preferences reflect our reasons. I will argue that practical reasons can be characterised along two dimensions that influence our preferences: their balance and their weight. This is analogous to a similar characterisation of the way in which probabilities reflect the balance and weight of evidence in epistemology. In this paper, I will illustrate the distinction between the balance and weight of reasons, and show (...) how this is crucial for an adequate account of preference and choice. The upshot is a more complete picture of a particular kind of decision, labelled by Isaac Levi and, more recently, Ruth Chang as ‘hard choices’. These are choices in which one option is better than another in some ways, the other is better than the first in some ways, but neither seems better overall. The distinction between the balance and weight of reasons presents a new way of understanding how hard choices vary by degree and what it is that makes them so hard. (shrink)

Philosophy in community projects provide powerful, immersive introductions to philosophical thinking for both children and tertiary students. Such introductions can jumpstart transformative learning as well as diversify who seeks out philosophy in the longer term, both in schools and in universities. Using survey responses from teachers, parents, participants, staff, and volunteers of two such programs – Eurekamp Oz! and philosothons – we show how participants find value in engaging in communities of inquiry and philosophical thinking more broadly. We argue correspondingly (...) that such philosophy in community projects are an asset to universities, both as highly successful university outreach programs and in offering high school, undergraduate, and postgraduate students mentoring and employment opportunities utilising their growing philosophical skills. For these reasons, philosophy in community programs provide alternative and supplementary pathways into sustained philosophical thinking to those available within traditional philosophy in the classroom approaches.

This book advocates a radical shift of concern in philosophical, historical, and sociological studies of the sciences, and explores the consequences of such a shift. The historically-oriented first part of the work deals with the ways in which ranges of questions become real and cease to be real for communities of inquirers. The more philosophically-oriented second part of the work introduces the notion of absolute reality of questions, and addresses doubt about the claims of the sciences to have accumulated absolutely (...) real questions. It is argued that recent studies in the sociology and social history of the science pose strong challenges to the sciences by revealing how appeals to authority, vested interests, and rhetorical and aesthetic sensibilities play substantial roles in the practices of the sciences. The final chapter defends the pragmatic stance of the work, and of its companion, The Fortunes of Inquiry, and draws morals about the roles of criticism and reflection in the philosophy of science and in the sciences themselves.

Block’s well-known distinction between phenomenal consciousness and access consciousness has generated a large philosophical literature about putative conceptual connections between the two. The scientific literature about whether they come apart in any actual cases is rather smaller. Empirical evidence gathered to date has not settled the issue. Some put this down to a fundamental methodological obstacle to the empirical study of the relation between phenomenal consciousness and access consciousness. Block (2007) has drawn attention to the methodological puzzle and attempted to (...) answer it. While the evidence Block points to is relevant and important, this paper puts forward a more systematic framework for addressing the puzzle. To give it a label, the approach is to study phenomenal consciousness as a natural kind. The approach allows consciousness studies to move beyond the initial means of identifying instances of the kind, like verbal report, and to find its underlying nature. It is wellrecognised that facts about an underlying kind may allow identification of instances of the kind that do not match the initial means of identification (cp. non-liquid samples of water). This paper shows that the same method can be deployed to investigate phenomenal consciousness independently of access consciousness. (shrink)

The authors explore the history of experiments in economics, provide examples of different types of experiments and show that the growing use of experimental methods is transforming economics into an empirical science.

This book confronts the threats of epistemic relativism and Pyrrhonian scepticism to analytic philosophy. Epistemic relativists reject absolute notions of knowledge and justification, while sceptics claim that knowledge and justification of any kind are unattainable. If either of these views is correct, then there can be no objective basis for thinking that one set of methods does a better job of delivering accurate information than any other set of methods. Philosophers have generally sought to resist these threats by responding to (...) the argument that seems to motivate both positions: the Agrippan trilemma. Steven Bland argues that this is a mistaken strategy. He surveys the most influential responses to the Agrippan trilemma, and shows that none of them succeeds in undermining epistemic relativism. Bland also offers a new, dialectical strategy of challenging epistemic relativism by uncovering how epistemic methods depend on one another for their applications. By means of this novel analysis, the book concludes that there are principled reasons to prefer naturalistic to non-naturalistic methods, even if these reasons do little to ease the threat of scepticism.

This paper examines three programmatic responses to the problem of cognitive bias: virtue epistemology, epistemic paternalism, and epistemic collectivism. Each of these programmes focuses on asinglelevel of epistemic analysis: virtue theorists on individuals, paternalists on environments, and collectivists on groups. I argue that this is a mistake in light of the fact that cognitive biases arise frominteractionsbetween these three domains. Consequently, epistemologists should spend less time defending these programmes, and more timecoordinatingthem. This paper offers empirically based arguments for the interactionist (...) approach, and contends that its adoption is an essential step for minimizing bias in empirical science. (shrink)

Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In _Humanity's End,_ Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines (...) the proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve "longevity escape velocity"; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.

The chapter outlines Nietzsche's view of decadence, its history and effects. The philosopher held decadence to be any condition, deceptively thought good, which limits what something or someone can be. This concept informs his critical and affirmative projects, acting as a versatile tool to identify and overcome his own decadence and to resist the decadence of Western culture. Decadence appears in five major areas of concern to Nietzsche: physiology; psychology; art and artists; politics; and philosophy. Physical and mental phenomena provide (...) the substrate of his understanding, but they manifest in cultural, political, and philosophical forms that, in turn, affect the body and mind. In each of the five areas, the concept of decadence for Nietzsche serves 1) to unmask valued cultural phenomena as corrupt, 2) to name and analyze degenerate effects, and 3) to spur reflection on how to respond.

This paper has four aims: first, to outline the role of the sceptical problem of the criterion in the principal argument for epistemic relativism; second, to establish that methodist and particularist responses to the problem of the criterion do not, by themselves, constitute successful strategies for resisting epistemic relativism; third, to argue that a more fruitful strategy is to attempt to evaluate epistemic frameworks on the basis of the epistemic resources that they have in common; and finally, to make the (...) case that finding this common ground will necessarily involve determining how it is that a framework’s constituent epistemic methods depend on one another for not only their warrant, but for their application.

While there are many competing accounts and scales of intellectual humility, philosophers and psychologists are generally united in treating it as an epistemically _beneficial_ disposition of _individual_ agents. I call the research guided by this supposition the _traditional approach_ to studying intellectual humility. The traditional approach is entirely understandable in light of recent findings that individual differences in intellectual humility are associated with various deleterious epistemic tendencies. Nonetheless, I argue that its near monopoly has resulted in an underestimation of important (...) limitations of human cognition. In particular, it neglects the fact that intellectual arrogance can be both deeply recalcitrant and significantly beneficial for bounded cognitive agents whose reliance on one another is profound. I propose to integrate these insights into the study of intellectual humility by treating it as a _collective virtue_ that gets manifested in the structure of epistemic environments. More specifically, it is an interactive virtue that harnesses and constrains intellectual arrogance to yield benefits for both individuals and collectives. I claim that this can happen only within _humbling environments_, such as forecasting tournaments and open institutional science. (shrink)

The question of whether it is permissible to quantify into a modal context is re-examined from an empiricist perspective. Following Wiggins, it is argued that an ontology of continuants implies essentialism, but it is also argued, against Wiggins, that the only conception of necessity that we need to start out with is that of analyticity. Essentialism, of a limited kind, can then be actually generated from this. An exceptionally fine-grained identity criterion for continuants is defended in this context. The debate (...) between Wiggins and Ayer over the legitimacy of de re modality is then examined in the light of these results, and it is argued that my position is consistent with Ayer’s minimalist assumptions. It is also argued that non-continuants will not sustain the essential/accidental distinction, thus giving some concessions to the sceptics. It is also shown that there are close connections between these issues and the more modern two-dimensionalist way of disentangling the necessary from the a posteriori, and that the latter needs to learn from the former.
