The social consequences of extending the human life span might be quite bad; perhaps the worst outcome is that power could be concentrated into ever fewer hands, as those who wield it gave way more slowly to death and disease. But the worry that more life would damage individuals' quality of life is not persuasive. Depending on what the science of aging makes possible, and on how people plan their lives, longer life might even facilitate a richer and deeper life.

New C. elegans studies imply that lipases and lipid desaturases can mediate signaling effects on aging. But why might fat homeostasis be critical to aging? Could problems with fat handling compromise health in nematodes as they do in mammals? The study of signaling pathways that control longevity could provide the key to one of the great unsolved mysteries of biology: the mechanism of aging. But as our view of the regulatory pathways that control aging grows ever clearer, the nature of (...) aging itself has, if anything, grown more obscure. In particular, focused investigations of the oxidative damage theory have raised questions about an old assumption: that a fundamental cause of aging is accumulation of molecular damage. Could fat dyshomeostasis instead be critical? (shrink)

Plato's Phaedo is a literary gem that develops many of his most famous ideas. David Ebrey's careful reinterpretation argues that the many debates about the dialogue cannot be resolved so long as we consider its passages in relative isolation from one another, separated from their intellectual background. His book shows how Plato responds to his literary, religious, scientific, and philosophical context, and argues that we can only understand the dialogue's central ideas and arguments in light of its overall structure. (...) This approach yields new interpretations of the dialogue's key ideas, including the nature and existence of 'Platonic' forms, the existence of the soul after death, the method of hypothesis, and the contemplative ethical ideal. Moreover, this comprehensive approach shows how the characters play an integral role in the Phaedo's development and how its literary structure complements Socrates' views while making its own distinctive contribution to the dialogue's drama and ideas.

As David White explains in the Introduction to Tantra in Practice, Tantra is an Asian body of beliefs and practices that seeks to channel the divine energy that grounds the universe, in creative and liberating ways. The subsequent chapters reflect the wide geographical and temporal scope of Tantra by examining thirty-six texts from China, India, Japan, Nepal, and Tibet, ranging from the seventh century to the present day, and representing the full range of Tantric experience--Buddhist, Hindu, Jain, and even (...) Islamic. Each text has been chosen and translated, often for the first time, by an international expert in the field who also provides detailed background material. Students of Asian religions and general readers alike will find the book rich and informative. The book includes plays, transcribed interviews, poetry, parodies, inscriptions, instructional texts, scriptures, philosophical conjectures, dreams, and astronomical speculations, each text illustrating one of the diverse traditions and practices of Tantra. Thus, the nineteenth-century Indian Buddhist Garland of Gems, a series of songs, warns against the illusion of appearance by referring to bees, yogurt, and the fire of Malaya Mountain; while fourteenth-century Chinese Buddhist manuscripts detail how to prosper through the Seven Stars of the Northern Dipper by burning incense, making offerings to scriptures, and chanting incantations. In a transcribed conversation, a modern Hindu priest in Bengal candidly explains how he serves the black Goddess Kali and feeds temple skulls lentils, wine, or rice; a seventeenth-century Nepalese Hindu praise-poem hammered into the golden doors to the temple of the Goddess Taleju lists a king's faults and begs her forgiveness and grace. An introduction accompanies each text, identifying its period and genre, discussing the history and influence of the work, and identifying points of particular interest or difficulty. The first book to bring together texts from the entire range of Tantric phenomena, Tantra in Practice continues the Princeton Readings in Religions series. The breadth of work included, geographic areas spanned, and expert scholarship highlighting each piece serve to expand our understanding of what it means to practice Tantra. (shrink)

This article concerns Quentin Meillassoux’s claim that Kant’s revolution is responsible for philosophy’s catastrophic loss of the ‘great outdoors’, of our knowledge of things as they are in themselves. I argue that Meillassoux’s critique of Kant’s ‘weak’ correlationism and his defence of ‘strong’ correlationism are predicated on a fallacious argument (termed ‘the Gem’ by David Stove) and the traditional, but in my view mistaken, metaphysical interpretation of Kant’s transcendental distinction. I draw on Henry Allison’s interpretation of Kant’s idealism to (...) argue that when Kant’s transcendental distinction is understood epistemologically we can avoid the fallacious reasoning underpinning Meillassoux’s argument, and at the very least attenuate his concerns about the ‘Kantian catastrophe’.

In this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a (...) form of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use (...) in other populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

A collection of 14 essays honoring the life and work of Oxford philosopher Wiggins touching on topics from ancient philosophy to ethics, metaphysics and the theory of meaning. The contributing scholars debate many of the seminal issues of Wiggins' work, including the determinancy of distinctness, relative identity, naturalism in ethics, logic and truth in moral judgments, and the practical wisdom of Aristotle. The collection uniquely features replies by Wiggins to each of the papers. Annotation copyright by Book News, Inc., Portland, (...) OR. (shrink)

The identity of indiscernibles states that indiscernible objects must be identical. Many philosophers have held that the PII turns out to be either true but trivial, or non-trivial but false, depending on how the notion of discernibility is spelled out. In this paper, I propose and defend an account of this notion which aims to yield a minimally non-trivial and yet plausible version of the PII. I argue moreover that this version of the principle is immune to a number of (...) well-known and recent objections to the PII. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Reading David Hume’s “Of the Standard of Taste.” ed. by Babette BabichTina BaceskiBabette Babich, ed. Reading David Hume’s “Of the Standard of Taste.” Berlin: deGruyter, 2020. Pp. VII + 333. ISBN: 978-3-11-058564-3, paper, $24.99.Reading David Hume’s “Of the Standard of Taste,” a volume of essays edited by Babette Babich, purports to offer the reader a “collective stud[y]” of Hume’s famous essay and its related concerns. (...) Almost all the contributions have previously been published, either as journal articles or book chapters. “Of the Standard of Taste” is helpfully included at the beginning of the volume, though Hume Studies readers will already be familiar with the text. The book is divided into five parts. The editor’s introduction comprises part I. Hume’s essay makes up the entirety of part II. Parts III–V are organized around different general themes, with each part containing from three to five essays. In total the book contains twelve essays.Hume’s “Of the Standard of Taste” is a “classic” work in aesthetics today, but what entitles it to this appellation? Indeed, why do we judge any work to be of “classical value?” “Taste” plays a central role in evaluations of this sort, particularly the “taste” of modern scholars. But, as Hume knew, the historical sensibilities of judges are liable to change over the years, and so “some things that appear in their day to be sure classics, things that have until then withstood the test of time, can undergo a shift in value for another era” (13). In her Introduction, Babich tells an engaging, if not always easy to follow, story about Hume’s “deathbed readings” to illustrate the point. From final conversations with Adam Smith, we know that Hume was reading Lucian’s Dialogues of the Dead. But which of Lucian’s several such dialogues was he reading? When the question was put to Annette Baier (who was at that time herself writing about Hume and “last things”), she confessed to being puzzled by the very [End Page 341] question (6). Baier’s initial puzzlement and subsequent investigations to resolve this confusion revealed just how much her own sensibilities diverged from those of Hume’s day. Babich observes: “[T]he Lucian who was popular in Hume’s own day and even through to the beginning of the twentieth century, has today so diminished in “classical” value that he is sufficiently esoteric that Hume scholars like Baier have trouble tracking him down” (13). My own initial confusions reading the Introduction are likely attributable, in part, to the fact that I, too, was unfamiliar with Lucian. Ironically, this fact is, itself, further evidence of Babich’s point: yesterday’s literary gems have dimmed in value today because modern scholars are not conversant with their works. I have already ordered my copy of Lucian.The book’s rationale is explained as follows: “The entire concern of this volume is all about the critical basis for such claims [which works have “classical” value]. How can we determine a standard for estimating tomorrow’s likely classic, whether in the literary domain or other areas where taste plays a role” (14)? There is more at stake with respect to Hume’s “Of the Standard of Taste,” however, than merely predicting “literary futures.” The question concerning a standard of taste has important consequences for improving judgments in a much wider arena: art more broadly (painting, architecture, sculpture, etc.), but perhaps also science and even economics, to mention but a few. Only one of the essays collected here takes up the topic of “classical value” and “literary futures” per se: the editor’s own. The reader is left to make out what they can from the various contributions. But the essays can all advance the discussion insofar as each one attempts to shed light on an important related concern, e.g., the nature of taste, the nature of a standard, influences on taste, and so on. In what follows, I will offer a brief account of some of the essays in parts III–V, so the reader can get an overall flavor (taste) of the volume.Part III... (shrink)

Why study notations, diagrams, or more broadly the variety of nonverbal “representations” or “signs” that are used in mathematical practice? This chapter maps out recent work on the topic by distinguishing three main philosophical motivations for doing so. First, some work (like that on diagrammatic reasoning) studies signs to recover norms of informal or historical mathematical practices that would get lost if the particular signs that these practices rely on were translated away; work in this vein has the potential to (...) broaden our view of the specific normativity of mathematics beyond logical proof. Second, some work focuses on signs to highlight the open-ended and “nonrigorous” aspects of mathematical practice, and the role of these aspects in the historical development of mathematics. The third motivation is based on the following observation: the reason differences in signs matter in mathematics is that humans are finite agents, with cognitive and computational limitations. Accordingly, studying signs can be a way to study how human computational constraints shape the mathematics that we do, and to tackle the topic of mathematical understanding. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

According to dispositionalism about modality, a proposition <p> is possible just in case something has, or some things have, a power or disposition for its truth; and <p> is necessary just in case nothing has a power for its falsity. But are there enough powers to go around? In Yates (2015) I argued that in the case of mathematical truths such as <2+2=4>, nothing has the power to bring about their falsity or their truth, which means they come out both (...) necessary and not possible. Combining this with axiom (T), it is easy to derive a contradiction. I suggested that dispositionalists ought to retreat a little and say that <p> is possible just in case either p, or there is a power to bring it about that p, grounding the possibility of mathematical propositions in their truth rather than in powers. Vetter’s (2015) has the resources to provide a response to my argument, and in her (2018) she explicitly addresses it by arguing for a plenitude of powers, based on the idea that dispositions come in degrees, with necessary properties a limiting case of dispositionality. On this view there is a power for <2+2=4>, without there being a power to bring about its truth. In this paper I argue that Vetter’s case for plenitude does not work. However, I suggest, if we are prepared to accept metaphysical causation, a case can be made that there is indeed a power for <2+2=4>. (shrink)

In order to effectively communicate information, the choice of representation is important. Ideally, a chosen representation will aid readers in making desired inferences. In this paper, we develop the theory of observation: what it means for one statement to be observable from another. Using observability, we give a formal characterization of the observational advantages of one representation of information over another. By considering observational advantages, people will be able to make better informed choices of representations of information. To demonstrate the (...) benefit of observation and observational advantages, we apply these concepts to set theory and Euler diagrams. In particular, we can show that Euler diagrams have significant observational advantages over set theory. This formally justifies Larkin and Simon’s claim that “a diagram is worth ten thousand words”. (shrink)

Japan and the Enemies of Open Political Science argues that Eurocentric blindness is a scientific failing, not a moral one. In a way true of no other political system, Japan's greatness has the potential to enliven and reform almost all the main branches of Western Political Science. David Williams criticizes Western social science, Anglo-American Philosophy and French Theory and explains why mainstream economists, historians of political thought and postculturalists have ignored Japan's modern achievements. Williams demonstrates why the renewal of (...) social science and the nurturing of a "a philosophy of the Pacific Century" requires a sustained act of intellectual demolition. (shrink)

Extant theoretical work on the political resource curse implies that dependence on resource revenues should decrease autocracies’ likelihood of democratizing but not necessarily affect democracies’ chances of survival. Yet most previous empirical studies estimate models that are ill-suited to address this claim. We improve upon earlier studies, estimating a dynamic logit model that interacts a continuous measure of resource dependence with an indicator of regime type using data from 166 countries, covering the period from 1816-2006. We find that an increase (...) in resource dependence at time t - 1 increases the likelihood of autocratic persistence at t, but has no appreciable effect on democratic survival. We go beyond existing empirical studies to show that increases in resource dependence have persistent and substantial cumulative effects on autocracies' likelihood of becoming democratic over the long-term, showing that the total effect of resource dependence on regime type is much larger than the short-term (one period) effect indicates.

This is an in-depth study of J.G. Fichte’s philosophy of mathematics and theory of geometry. It investigates both the external formal and internal cognitive parallels between the axioms, intuitions and constructions of geometry and the scientific methodology of the Fichtean system of philosophy. In contrast to “ordinary” Euclidean geometry, in his Erlanger Logik of 1805 Fichte posits a model of an “ursprüngliche” or original geometry – that is to say, a synthetic and constructivistic conception grounded in ideal archetypal elements that (...) are grasped through geometrical or intelligible intuition. -/- Accordingly, this study classifies Fichte’s philosophy of mathematics as a whole as a species of mathematical Platonism or neo-Platonism, and concludes that the Wissenschaftslehre itself may be read as an attempt at a new philosophical mathesis, or “mathesis of the mind.” -/- “This work testifies to the author's exact and extensive knowledge of the Fichtean texts, as well as of the philosophical, scientific and historical contexts. Wood has opened up completely new paths for Fichte research, and examines with clarity and precision a domain that up to now has hardly been researched.” Professor Dr. Marco Ivaldo -/- “This study, written in a language distinguished by its limpidity and precision, and constantly supported by a close reading of the Fichtean texts and secondary literature, furnishes highly detailed and convincing demonstrations. In directly confronting the difficult historical relationship between the Wissenschaftslehre and mathematics, the author has broken new ground that is at once stimulating, decidedly innovative, and elegantly audacious.” Professor Dr. Emmanuel Cattin.

In 1962, the philosopher Richard Taylor used six commonly accepted presuppositions to imply that human beings have no control over the future. David Foster Wallace not only took issue with Taylor's method, which, according to him, scrambled the relations of logic, language, and the physical world, but also noted a semantic trick at the heart of Taylor's argument. _Fate, Time, and Language_ presents Wallace's brilliant critique of Taylor's work. Written long before the publication of his fiction and essays, Wallace's (...) thesis reveals his great skepticism of abstract thinking made to function as a negation of something more genuine and real. He was especially suspicious of certain paradigms of thought-the cerebral aestheticism of modernism, the clever gimmickry of postmodernism-that abandoned "the very old traditional human verities that have to do with spirituality and emotion and community." As Wallace rises to meet the challenge to free will presented by Taylor, we witness the developing perspective of this major novelist, along with his struggle to establish solid logical ground for his convictions. This volume, edited by Steven M. Cahn and Maureen Eckert, reproduces Taylor's original article and other works on fatalism cited by Wallace. James Ryerson's introduction connects Wallace's early philosophical work to the themes and explorations of his later fiction, and Jay Garfield supplies a critical biographical epilogue. (shrink)

Human thought is unable to acknowledge the reality of affliction. To acknowledge affliction means saying to oneself: I may lose at any moment, through the play of circumstances over which I have no control, anything whatsoever I possess, including those things which are so intimately mine that I consider them as being myself. There is nothing that I might not lose.

David Williams explores the complex links between Condorcet as visionary ideologist and pragmatic legislator, and between his concept of modernity and the management of change. The Marquis de Condorcet was one of the few Enlightenment thinkers to witness and participate in the French Revolution. Based on an extensive array of printed and original manuscript sources, Williams' analysis of Condorcet's politics will be a major contribution to Enlightenment studies.

The author of this book has traced the major lines of argument over those years in a most engaging style with clear descriptions of the concepts and ideas.

This book puts forward a revisionist view of Japanese wartime thinking. It seeks to explore why Japanese intellectuals, historians and philosophers of the time insisted that Japan had to turn its back on the West and attack the United States and the British Empire. Based on a close reading of the texts written by members of the highly influential Kyoto School, and revisiting the dialogue between the Kyoto School and the German philosopher Heidegger, it argues that the work of Kyoto (...) thinkers cannot be dismissed as mere fascist propaganda, and that this work, in which race is a key theme, constitutes a reasoned case for a post-White world. The author also argues that this theme is increasingly relevant at present, as demographic changes are set to transform the political and social landscape of North America and Western Europe over the next fifty years.

The Discovery of Evolution explains what the theory of evolution is all about by providing a historical narrative of discovery. Some of the major puzzles that confront anyone studying living things are discussed and it details how these were solved from an evolutionary perspective. Beginning with the emergence of the early naturalists in the seventeenth century, the scientific discoveries that led up to and then flowed from Darwin and Wallace's theory of evolution by natural selection are then discussed, and finally (...) the modern evolutionary studies at the close of the twentieth century are detailed. This new edition of The Discovery of Evolution is fully updated and contains a new chapter on the evolutionary studies of the twentieth century. By approaching the topic of evolution in this way, it is made accessible to the non-specialist and no previous study of biology is required in order to read and understand this book. (shrink)

Receiving social support from community and extended family has been typical for mothers with infants in human societies past and present. In non-industrialised contexts, infants of mothers with extended family support often have better health and higher survival through the vulnerable infant period, and hence shared infant care has a clear fitness benefit. However, there is scant evidence that these benefits continue in industrialised contexts. Better infant health and development with allocare support would indicate continued evolutionary selection for allocare. The (...) research reported here used multiple logistic regression analysis to test whether a lack of family and other social support for mothers was associated with an increased risk of developmental delay in 9-month-old infants in the UK Millennium Cohort (analysis sample size, 15,696 infants). Extended family-based childcare during work hours and more maternal time spent with friends were the most influential kin and social support variables: infants of mothers with kin-based childcare versus all other childcare arrangements had a lower risk of developmental delay (OR = 0.61, 95% CIs: 0.46–0.82). Infants of mothers who spent no time with friends when compared with those who saw friends every day had double the odds of delay. Greater paternal involvement in infant care was associated with a lower odds of developmental delay. In conclusion, shared care of infants and social support for mothers may influence fitness-related traits in industrialised societies rather than being factors that influenced selection only in the past and in societies which retain close kin networks and a strong local community focus.
