Shors & Matzel's target article is a thought-provoking attempt to reconceptualise long-term potentiation as an attentional or arousal mechanism rather than a memory storage mechanism. This is incompatible with the facts of the neurobiology of attention and of the behavioural neurophysiological properties of hippocampal neurons.

Pains are subject to obvious, well-documented, and striking top-down influences. This is in stark contrast to visual perception, where the debate over cognitive penetrability tends to revolve around fairly subtle experimental effects. Several authors have recently taken up the question of whether top-down effects on pain count as cognitive penetrability, and what that might show us about traditional debates. I review some of the known mechanisms for top-down modulation of pain, and suggest that it reveals an issue with a relatively (...) neglected part of the cognitive penetrability literature. Much of the debate inherits Pylyshyn’s stark contrast between transducers and cognition proper. His distinction grew out of his running fight with Gibson, and is far too strong to be defensible. I suggest that we might therefore view top-down influences on pain as a species of transducer calibration. This provides a novel but principled way to distinguish between several varieties of top-down effect according to their architectural features. (shrink)

Schopenhauer repeatedly claims that suicide is both foolish and futile. But while many commentators have expressed sympathy for his charge of foolishness, most regard his charge of futility as indefensible even within his own system. In this paper, I offer a defense of Schopenhauer’s futility charge, based on metaphysical and psychological considerations. On the metaphysical front, Schopenhauer’s view implies that psychological connections extend beyond death. Drawing on Parfit’s discussion of personal identity, I argue that those connections have personal significance, such (...) that suicide does not allow one, as Hamlet hopes, simply “not to be.” On the psychological front, I argue that a distinction between agents’ intentions and underlying desires makes room for Schopenhauer to claim that paradigmatic suicidal agents ultimately desire the opposite of what suicide accomplishes. I conclude by showing how the resulting account of futility can buttress the charge of foolishness as well. My interpretation still leaves Schopenhauer vulnerable to certain objections, but shows that his account is significantly more defensible than previous commentators have realized. (shrink)

Nanotechnology thrives in the realm of the virtual. Throughout its history, the field has been shaped by futuristic visions of technological revolution, hyperbolic promises of scientific convergence at the molecular scale, and science fiction stories of the world rebuilt atom by atom. Even today, amid the welter of innovative nanomaterials that increasingly appear in everyday consumer products—the nanoparticles enhancing our sunscreens, the carbon nanotubes strengthening our tennis rackets, the antimicrobial nano-silver lining our socks, the nanofilms protecting our wrinkle-free trousers—the public (...) rhetoric of nanotechnology constantly reminds us that such precision-engineered materials merely represent a trace or a premonition of the amazing future still to come...

ABSTRACTOscar Larsson’s sympathetic critique of constructivist institutionalism calls for a clarification of my understanding of subjectivity, inter-subjectivity, and their mutual interdependence. That interdependence lies at the heart of any genuinely constructivist approach, just as the interdependence of structure and agency lies at the heart of any genuinely institutionalist approach. As such, I reject the charge of subjectivism just as I would that of voluntarism. Building on the social ontology of Berger and Luckmann, we can distinguish between subjectivity and intra-subjectivity and (...) proceed to show how the latter implies a notion of inter-subjectivity. An example of the social construction of a political crisis shows that social facts are made and remade through a fusion of inter- and intra-subjectivities. (shrink)

In this chapter I explore the reciprocal relationship between the metaphysical views mathematicians hold and their mathematical activity. I focus on the set-theoretic pluralism debate, in which set theorists disagree about the implications of their formal mathematical work. As a first case study, I discuss how Woodin’s monist argument for an Ultimate-L feeds on and is fed by mathematical results and metaphysical beliefs. In a second case study, I present Hamkins’ pluralist proposal and the mathematical research projects it endows with (...) relevance. These case studies support three claims: (1) the metaphysical views of mathematicians can shape what counts as relevant research; (2) mathematical results can shape the metaphysical beliefs of mathematicians; (3) metaphysical thought and mathematical activity develop in tandem in mathematical practices. This makes metaphysical thought an integral part of mathematical practices. (shrink)

Nicolas Malebranche (1638-1715) holds that the senses, imagination, and passions aim at survival and the satisfaction of the body’s needs, rather than truth or the good of the mind. Each of these faculties makes a distinctive and, indeed, an indispensable contribution to the preservation of life. Commentators have largely focused on how the senses keep us alive. By comparison, the imagination and passions have been neglected. In this paper, I reconstruct Malebranche’s account of how the imagination contributes to the preservation (...) of the body by compensating for the limitations of the senses. First, the imagination represents non-actual states of affairs, such as probable or possible future states. Second, the imagination forges new and often helpful associations based on past experiences. Third, the imagination (mis)represents that objects will cause pleasure and pain, thereby imbuing them with emotional significance they would otherwise lack. Together, these features flesh out Malebranche’s view that the imagination is necessary for the preservation of life. (shrink)

A book on human communication that is worthy of its subject must introduce the reader to the dynamic interaction of a number of diverse fields. Colin Cherry's book, over successive editions, has served for twenty years as perhaps the most literate and readable introduction to this interaction available. Readers have consistently found that fields within their specialty are covered with authority; that fields far removed are covered with clarity; and that the connections among them are shown to be close (...) and natural. This third edition includes a new chapter, "Feeling, Knowledge, and Understanding," that extends the book's reach into philosophy, and in particular communicates some existential points-of-view. In it the author undertakes to demonstrate that "The language of physical science is inadequate for discussion of what is essentially human about human communication." In addition, numerous changes have been introduced throughout the text, and the bibliography has been expanded and updated. (shrink)

In recent years there has been a bold revival in the field of natural theology, where “natural theology” can be understood as the attempt to demonstrate that God exists by way of reason, evidence, and argument without the appeal to divine revelation. Today's practitioners of natural theology have not only revived and recast all of the traditional arguments in the field, but, by drawing upon the findings of contemporary cosmology, chemistry, and biology, have also developed a range of fascinating new (...) ones. -/- Contemporary Arguments in Natural Theology brings together twenty experts working in the field today. Together, they practice natural theology from a wide range of perspectives, and show how the field of natural theology is practiced today with a degree of diversity and confidence not seen since the Middle Ages. Aimed primarily at advanced undergraduates and graduate students, the volume will also be of interest to researchers in philosophy, theology, biblical studies, and religious studies, as an indispensable resource on contemporary theistic proofs.

Frege maintains that there are not two distinct acts, assertion and denial; rather, denying p is one and the same as asserting not-p. Wittgenstein appears not to recognise this identity in Frege, attributing to him the contrary view that a proposition may have one of two verbs, "is true" or "is false". This paper explains Wittgenstein’s attribution as a consequence of Frege’s treatment of content as theoretically prior to the act of judgment. Where content is prior to judgment, the denial (...) of p—what is rejected in asserting p—is distinct from the assertion of not-p. Wittgenstein’s own embrace of Frege’s identity is then considered, an embrace explained in part by his repudiation of Frege’s theoretical order. (shrink)

In this paper I argue that individuals are, prior to the existence of just institutions requiring that they do so, bound as a matter of global distributive justice to restrict their use, or share the benefits fairly of any use beyond their entitlements, of the Earth’s capacity to absorb greenhouse gases (EAC) to within a specified justifiable range. As part of the search for an adequate account of climate morality, I approach the task by revisiting, and drawing inspiration from, two (...) prominent models from classical political philosophy for thinking about norms (rights, permissions, limits, etc.) regarding “pre-institutional” appropriation of unowned resources; Locke and Kant, respectively. The basic resources they develop—connected to fundamental norms of equality and rights to self-preservation and freedom—in order to generate their particular schema for distributive shares prior to the existence of just institutions can be usefully and plausibly connected up with the scarce, valuable, rival, non-excludable, global, and unowned resource that is EAC in order to undergird a picture of individual climate duties in the contemporary world. It is a picture that comes with some fairly radical implications, especially for the well-off. (shrink)

This paper is about the underlying logical principles of scientific theories. In particular, it concerns ex contradictione quodlibet (ECQ) the principle that anything follows from a contradiction. ECQ is valid according to classical logic, but invalid according to paraconsistent logics. Some advocates of paraconsistency claim that there are ‘real’ inconsistent theories that do not erupt with completely indiscriminate, absurd commitments. They take this as evidence in favor of paraconsistency. Michael (2016) calls this the non-triviality strategy (NTS). He argues that this (...) strategy fails in its purpose. I will show that Michael's criticism significantly over-reaches. The fundamental problem is that he places more of a burden on the advocate of paraconsistency than on the advocate of classical logic. The weaknesses in Michael's argument are symptomatic of this preferential treatment of one viewpoint in the debate over another. He does, however, make important observations that allow us to clarify some of the complexities involved in giving a logical reconstruction of a theory. I will argue that there are abductive arguments deserving of further consideration for the claim that paraconsistent logic offers the best explanation of the practice of inconsistent science. In this sense, the debate is still very much open. (shrink)

Peter Carruthers argues that phenomenal consciousness might not matter very much either for the purpose of determining which nonhuman animals are appropriate objects of moral sympathy, or for the purpose of explaining for the similarities in behavior of humans and nonhumans. Carruthers bases these claims on his version of a dispositionalist higher-order thought (DHOT) theory of consciousness which allows that much of human behavior is the result of first-order beliefs that need not be conscious, and that prima facie judgments about (...) the importance of consciousness are due to confabulation. We argue briefly against his claim that ‘the moral landscape can remain unchanged’ even if all or nearly all nonhuman animals are taken to be incapable of conscious experience. We then show how a first-order representational (FOR) theory of consciousness might be defended against Carruthers’ criticisms. Finally, we argue that Carruthers’ appeal to confabulation undercuts his own arguments for an evolutionary explanation for consciousness, posing a greater epiphenomenalist threat to his DHOT theory than he concedes.

Structuralism in philosophy of mathematics has largely focused on arithmetic, algebra, and basic analysis. Some have doubted whether distinctively structural working methods have any impact in other fields such as differential equations. We show narrowly construed structuralism as offered by Benacerraf has no practical role in differential equations. But Dedekind’s approach to the continuum already did not fit that narrow sense, and little of mathematics today does. We draw on one calculus textbook, one celebrated analysis textbook, and a monograph on (...) the Navier–Stokes equation to show structural methods like Dedekind’s have long been central to differential equations, and have philosophically respectable ontology and epistemology.

For 300 years, Fermat’s Last Theorem seemed to be pure arithmetic little connected even to other problems in arithmetic. But the last decades of the twentieth century saw the discovery of very special cubic curves, and the rise of the huge theoretical Langlands Program. The Langlands perspective showed those curves are so special they cannot exist, and thus proved Fermat’s Last Theorem. With many great contributors, the proof ended in a deep and widely applicable geometric result relating nice curves in (...) rational coordinates to very nice surfaces in complex coordinates. This geometry is the only proof strategy for FLT yet known. Outstanding but not atypical of current mathematics, the proof challenges common philosophic views on abstraction and structure and raises still-open logical questions in arithmetic. (shrink)

In this chapter, I taxonomize early modern modes of relating self-interest and the common good. I discuss Protestant natural law theory, republicanism, utilitarianism, and—my main focus—Scottish social thought from Adam Smith and others. My aim is twofold. First, historically, I lay out the conceptual field for the early modern relation of self-interest and the common good while giving special attention to Scottish innovations. Second, from a philosophical point of view, I argue that the Scottish theory of the common good offers (...) some of the best conceptual resources for considering the relation of individual and community in present-day large, industrial nation-states and empires. More specifically, I claim that the Scots develop a concept of the common good that is (1) more social and economic than its alternatives, (2) more systemic and less dependent on the psychology and intentions of individuals, and (3) less tied to thick notions of community (including the state) and more amenable to empire. I conclude by bringing out the significance of these claims for our thinking about self-interest, the common good, and community. (shrink)

The following review summarizes and examines Mark Solms's article Dreaming and REM Sleep are controlled by different brain mechanisms, which argues why the understanding of REM sleep as the physiological equivalent of dreaming needs to be re-analyzed. An analysis of Solms's article demonstrates that he makes a convincing argument against the paradigmatic activation-synthesis model proposed by Hobson and McCarley and provides provocative evidence to support his claim that REM and dreaming are dissociable states. In addition, to situate Solms's findings in (...) concurrent research, other studies are mentioned that are further elucidated by his argument. [Solms]. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leo Strauss on Plato's Euthyphro ed. Hannes Kerber, and Svetozar Y. MinkovColin David PearsKERBER, Hannes, and Svetozar Y. Minkov, editors. Leo Strauss on Plato's Euthyphro. University Park: Pennsylvania State University Press, 2023. vii + 231 pp. Cloth, $74.95; paper, $22.95Leo Strauss is an enigmatic figure in the landscape of political philosophy, deeply committed to the restoration of political philosophy as the premiere discipline in academia. He spent his (...) career working to reopen le querelle des anciens et des modernes and the theologico-political problem underlying those tensions. Though, as the editors of this volume point out, Strauss's motivations were not merely historiographic and the evolution of his thought was not without significant, if fruitful, setbacks.Strauss's early thought is defined by his engagement with Maimonides, and especially Philosophy and Law (1935). Without fully abandoning the [End Page 550] traditional interpretation of Maimonides as reconciling Jewish and Aristotelian philosophy, Strauss advances Maimonides as an esoteric thinker with a more complex and nuanced philosophic perspective. Strauss later turned to al-Farabi, who like Maimonides grapples with the complex interrelation of reason, revelation, and the role of philosophy. It was during this era that Strauss, having just fled Nazi Germany in 1938, confirmed his view of esoterism in philosophic writing and jettisoned limited traditional interpretations.However, these phases of Strauss's early development prove short-lived. In 1946, Strauss "suffers" his famous "shipwreck," a profound philosophic crisis, which compelled him "to begin again from the beginning" (Strauss to Löwith, 1946). Al-Farabi had led Strauss back into a study of Plato and to the crisis of reason laid out in Plato's dialogues, the crux of which is the possibility that there may exist permanent limits on what philosophy or science can know about the fundamental nature of things. The implications this has regarding the legitimacy of divine revelation led to the "second sailing" suggested in the Phaedo, and to Strauss's complete reevaluation of the theologico-political problem.The present volume provides a view of Strauss's evolving thought immediately following his "shipwreck" and as he begins to critically elaborate on his view of the relationship between philosophy and religion. Included are Strauss's notebook on Plato's Euthyphro and Crito (1948), a draft of his first lecture on the Euthyphro (1950), notes for his second lecture on the Euthyphro and the text of the lecture itself (1952), as well as marginalia and selections from his copy of Plato's dialogue. Together, these materials make up the several layers surrounding the heart of Strauss's thought on the problems of justice and piety, or "whether the right and necessity of philosophy are completely evident."Reading this volume is an exercise in flipping back and forth between one section and another to the point where one is tempted to break the spine, separate the sections, and lay them out side by side. Strauss's notebook provides his line-by-line interpretation of the Platonic dialogues and forms the basis for both the draft of his first lecture, his notes on the second, and his 1952 lecture itself. Astute readers may already notice in the notebook how Strauss subtly opens up his view of piety, for example by taking seriously Euthyphro's first but formally flawed definition of piety and gradually refusing to position Euthyphro as a fool. Strauss's draft of his first lecture picks up the notebook's themes but still presents a view of piety more in line with the pro-philosopher stance presented early in the notes. By contrast, the 1952 lecture presents a more elegant formulation of Strauss's position, both in words and actions. That is, not only does the second lecture closely follow the notebook's nuanced exegesis, but it is also designed to stimulate the reader's thinking on the problems of justice and piety, rather than resolve these didactically.Strauss appears to have abandoned the approach he took in the first lecture in favor of an approach that echoed Plato's own presentation in the Euthyphro. He closes the 1952 lecture with two especially salient [End Page 551] points. Returning to his early claim... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Theory of Bioethics by David DeGrazia and Joseph MillumColin Hoy (bio) and Winston Chiong (bio)Review of David DeGrazia and Joseph Millum, A Theory of Bioethics (Cambridge University Press, 2021)David DeGrazia and Joseph Millum’s A Theory of Bioethics 2021 arrives at a curious time for an ambitious effort at systematic theory construction, seemingly out of step with bioethical fashion. At the same time, a prominent group of philosophical (...) bioethicists authored an article, possibly with a touch of defensiveness, to “make the case that philosophy and philosophers still have a very important and meaningful role to play in contemporary bioethics” (Blumenthal-Barby et al. 2021). Meanwhile, the annual meeting of the American Society for Bioethics and Humanities included several expressions of impatience with the historical privileging of philosophy over more empirical, situated, and community-oriented approaches to moral problems in health.DeGrazia and Millum’s work itself reflects the current state of bioethics and how it has changed since the heyday of grand bioethical theory construction in the late twentieth century. To apply Parfit’s philosophical taxonomy (1984), the general frameworks promulgated by theorists like Veatch, Engelhardt, and Gert, as well as Beauchamp and Childress, were by necessity revisionary. These bioethical theories were whole-cloth alternatives to a conventional and paternalistic medical ethos that was already widely acknowledged as unsatisfactory. Today, however, bioethics is a mature and institutionalized field, with well-established practices and a corpus of accepted tenets (alongside matters of ongoing but generally demarcated controversy). A plausible and fruitful contemporary theory of bioethics must be largely descriptive, in Parfit’s sense, providing an intellectual framework that gives coherence and sense to existing practice, while at the same time clarifying matters of confusion.In contemporary bioethics, a central component of this practice is the application of the four principles of biomedical ethics—non-maleficence, beneficence, justice and autonomy—not merely as originally proposed by Beauchamp and Childress (2019), but in their refined form, following decades of exchange, critique, and revision. DeGrazia and Millum’s theory begins with two core values: well-being and respect for rights holders. [End Page 321] The bulk of the book then applies the method of reflective equilibrium to specify these two values in terms of the canonical four principles, here treated as “mid-level” constructs with readier application to specific cases than the two core values. Experienced bioethicists may have an uncanny sense of setting off from a new trailhead, and yet, eventually finding themselves still walking a familiar path. However, this way of introducing and explicating the four principles will likely be more accessible to a wider audience, including high-level undergraduates and graduate students not already versed in the revisions, refinements, and compromises embedded in Beauchamp and Childress’s discussions.Two other features recommend this book as a resource for trainees and interested non-experts seeking to deepen their understanding of bioethics. First, the clarity of its style and organizational approach provides a welcome orientation for non-specialists. The chapters are structured so that major contending perspectives are outlined before the authors develop arguments for their own positions in that context. Each chapter proceeds by considering applications of the broader theory, showing how it can illuminate potential candidate approaches or policies, as well as demonstrating how to use the tools of ethical analysis to evaluate these proposals in both ideal and non-ideal cases. This didactic approach to the relationship between conceptual argument and practice will be accessible to many who are initially unfamiliar with or intimidated by theory. Second the commendable decision to make the book electronically available and accessible also has the potential to broaden the reach of the work, and in particular, to engage parties in under-resourced settings, which have so often been overlooked in bioethical discourse.As noted above, while the authors’ approach is descriptive in Parfit’s sense, it is not necessarily conservative. In many places, the authors highlight how their theory includes elements or renders conclusions that are not broadly accepted, and following the method of reflective equilibrium, they advocate for these positions both in terms of broad principles and particular judgments about cases. This begins with their dual-value... (shrink)

An argument has been recently proposed by Watkins, whose objective is to show the impossibility of a statistical explanation of single events. This present paper is an attempt to show that Watkins's argument is unsuccessful, and goes on to argue for an account of statistical explanation which has much in common with Hempel's classic treatment.

The term ‘space’ is inherently geographical. Educational provision and activity takes place within spaces ranging from a room at home or in a school to a campus to an administrative area which could be a state within a country, a whole country or a group of countries. Such spaces are known as geographical surfaces. Within these spaces the process of learning and teaching takes place at particular points that are often nodes in a network which may be formal, such as (...) a group of schools or universities, or non-formal, such as in cyberspace. Understanding what goes on depends on the scale at which it is observed, ranging from individuals to global outreach. Altogether, this constitutes the geography of educational reality. This comprehensive volume includes a theoretical background, plus a sample of situations including school level, policy and administration, inequitable access, education hubs, and small states. It offers an introduction to a relatively neglected member of the family of education foundation disciplines, the geography of education. This book was originally published as a special issue of _Comparative Education. _. (shrink)

This paper will proceed from the assumption of scholars like Anne Fernihough, Peter Fjagsund, Michael Black, and Michael Bell that there are sufficient connecting links between the literary oeuvre of D.H. Lawrence and the philosophizing of Martin Heidegger that they warrant consideration in each other's company. The paper will attempt to provide more evidence for what these scholars have been contending. It seeks to make the case that although D.H. Lawrence and Martin Heidegger start from very different beginning points, the (...) one literary, the other epistemological (so to speak), they arrive at surprisingly similar conclusions about the deficiencies in the specifically modern way of viewing human existence and the world. The paper isolates certain of Lawrence and Heidegger's key passages relevant to the themes of science, humanism, art and death and reveals them as looking at these fundamental issues from a remarkably similar standpoint. These two metaphysicians were groping for the right path forward from the intellectual and social crises of the twentieth century and the evidence suggests they saw it as lying in the same direction.

Many traditional arguments in favor of enhancement are consequentialist in nature. Many of the classic arguments against enhancement seem to have loosely Kantian origins. In this paper I offer a different interpretation of what a Kantian should be committed to with respect to enhancement by focusing on Kant's sometimes overlooked imperfect duty to cultivate our talents. I argue that in promoting an end that Kant thinks we have a duty to set, enhancing is more than just permissible, but has morally (...) weighty reasons behind it and would in part constitute a duty we owe to ourselves. This shows that Kantians have a unique position to add to debates about enhancement and positions Kant as pushing a view that is potentially more radical than even most ethicists friendly to enhancement, who might grant that enhancement is permissible in a wide array of cases, but often fall short of judging it part of a duty we owe to ourselves.

In 1959, Richard Feynman suggested that the most compelling reason to pursue nanoscale research might be ‘just for fun.’ This article traces a history of playful images and ludic practices in nanotechnology. Two case studies—nanocars and nanosoccer—exemplify the ways in which scientific research mobilizes speculative futures, less through engineering design or stepwise protocol than through the recreational dynamics of play. Although such molecular toys might appear frivolous, they index the increasingly widespread conditions of play labor, or ‘playbor’, shaping today’s technoculture. (...) Exploring the processes of transmutation and transvaluation by which technological imaginaries are rendered operative, this article tells a story of how the nanoworld became an everyday reality by becoming a game.

According to Stephen Law’s “X-claim argument,” the theist’s acquiring (what I call) an “x-claim defeater” automatically provides the theist with a reason to give up her x-claim belief. Contrary to Law, I argue that, even if the theist acquires such a defeater, it does not follow that the theist ought to give up her x-claim belief. This is because the degree of justification possessed by the theist’s belief may be sufficient to epistemically insulate itself against the x-claim defeater that was (...) initially brought against it. Hence, the theist may be justified in maintaining her x-claim belief. (shrink)

Understanding the ethical importance of the Religion of Humanity therefore implies understanding the central role of imagination in Millian ethical life. This investigation serves to articulate a feature of Mill's utilitarianism that differentiates it from Bentham's, namely (...) his commitment to the importance of a religious sensibility in the moral agent. It also raises the broader philosophical issue of what narratives a psychologically tenable humanist world-view requires. (shrink)

: What would constitute just representation for the climate vulnerable? My purpose in this essay is to provide a critique of the default frame for approaching this question, as well as to offer a suggestion for expanding our conception of what an adequate answer should include. The standard frame conceives of representing vulnerable climate interests largely in terms of formal mechanisms of representation in technocratic and bureaucratic institutions. I show the limits of that standard approach and caution against the discussion (...) of climate representation being overly confined to the level of “formal” representation. I go on to detail the importance of thinking about more “informal” modes of representing vulnerable climate interests. In order to pursue both of these aims, I draw on lessons in meaningful representation and inclusion during postconflict peacebuilding. (shrink)

We question whether the postulated revenge and forgiveness systems constitute true adaptations. Revenge and forgiveness are the products of multiple motivational systems and capacities, many of which did not exclusively evolve to support deterrence. Anger is more aptly construed as an adaptation that organizes independent mechanisms to deter transgressors than as the mediator of a distinct revenge adaptation.
