This book is an edited collection on one of Plato’s most dramatic as well as most complex dialogues, where a defence of the philosopher’s way of life is carried out against the background of interconnected rhetorical and political stances of the time.

This essay develops a comparison between the Stoic and Daoist theories of emotions in order to provide a new interpretation of the emotional life of the wise person according to the Daoist classic Zhuangzi 莊子, and to shed light on larger divergences between the Greco-Roman and Chinese intellectual traditions. The core argument is that both Zhuangzi and the Stoics believed that there is a peculiar kind of emotional responses that emerge by themselves and are therefore wholly natural, since they do (...) not involve evaluative judgment and desire, and distinguished them sharply from emotions, or “passions,” that arise as a result of mistaken evaluative judgments and artificial additions to things as they are, as well as to self-emerging feelings themselves. It is argued that while both Zhuangzi and the Stoics acknowledged the natural and therefore normative status of self-emerging feelings, Zhuangzi assessed them more favorably than the Stoics. The final part of the essay suggests that this divergence can be ultimately traced to different dichotomies that structured the debates in both traditions: rational versus non-rational in the Greco-Roman tradition, and artificial versus natural in the Chinese.

We focus on the question of how expertise as conceived by the Stoics interacts with the content of impressions. In Section 1, we situate the evidence concerning expert perception within the Stoic account of cognitive development. In Section 2, we argue that the content of rational impressions, and notably of expert impressions, is not exhausted by the relevant propositions. In Section 3, we argue that expert impressions are a subtype of kataleptic impressions which achieve their level of clarity and distinctness (...) due to the contribution of expertise. In Section 4, we argue that the expertise in living well not only allows the wise person to assent correctly but also affects the content of her impressions. We suggest that these two models – one’s attitude toward an impression being informed by expertise, and one’s impressions being affected by expertise – might characterize distinct stages of cognitive development. Stoic wisdom is not only a matter of the way one assents to one’s impressions but also a matter of the condition of one’s soul and, consequently, of the kinds of impressions one even entertains. Expertise offers a model of how cognitive and discriminatory improvement through practice and effort can transform the non-wise into the wise. A reading on which the content of impressions is not exclusively propositional illuminates a further aspect of this transformation. If the same propositions are accessible through impressions with different non-propositional content, we can account for cases in which the novice and the expert entertain the same proposition.

This article offers a new interpretation of Aristotle’s ambiguous and much-discussed claim that pleasure perfects activity. This interpretation provides an alternative to the two main competing readings of this claim in the scholarship: the addition-view, which envisages the perfection conferred by pleasure as an extra perfection beyond the perfection of activity itself; and the identity-view, according to which pleasure just is the perfect activity itself. The proposed interpretation departs from both these views in rejecting their assumption that pleasure cannot perfect (...) the activity itself, and argues that pleasure makes activity perfect by optimising the exercise of one’s capacities for that activity. Those who build or play music with pleasure do so better than those who do not delight in these activities. The basis of this interpretation is Aristotle’s little-read remarks from the following chapter, i. e. NE x.5, about how pleasure “increases” the activity. (shrink)

Comparisons between early Chinese Daoism and ancient Greco-Roman Stoicism have recently become quite popular with scholars working in Sino-Western comparative philosophy. It has been pointed out that there are fundamental similarities between the two schools in their commitment to the ideal of "following nature" or in their views about emotional detachment. In this comparative article, I would like to suggest that these similarities are even deeper than has so far been acknowledged, and that the existing differences between the two schools, (...) which we can grasp against this background of robust similarities, are therefore bound to be particularly pertinent with regard to our...

This article reconstructs grounds for Mengzi's view that moral self-cultivation, or the process of "nourishing the heart" (yangxin 養心), depends largely on minimizing the desires of the senses. I argue that these desires are detrimental for the growth of the heart in two different ways: directly, by distorting or desensitizing the heart's moral perception, and indirectly, by depriving it of its nutrients, that is, of the exercise of moral actions.

in book six of the Nicomachean Ethics, Aristotle famously argues that the excellences of the rational and nonrational parts of the soul, that is, practical wisdom and character virtue, are interdependent: "it is not possible to possess virtue in the primary sense [κυρίως] without wisdom, nor to be wise without virtue of character."1 The latter part of this claim—that it is impossible to be practically wise without character virtue—has been a particular topic of attention in the scholarship. While Aristotle does (...) give us an explanation of why two types of nonvirtuous agents necessarily lack practical wisdom,2 commentators have been puzzled by the... (shrink)

ABSTRACTThis article engages with a recent view that the Daoist Classic Zhuangzi advances an alternative to the Confucian role-ethics. According to this view, Zhuangzi opposes the Confucian idea that we should play our social roles with sincerity and instead argues that we should take the liberty to detach ourselves from the roles we play and ‘pretend’ them. It is argued in this article that Zhuangzi’s ideal of role-playing is based neither on sincerity nor on pretense. Instead, it is akin to (...) the excellence of theatre actors when they enact a role: they are able, for a limited time, to restructure their personality into a particular role, but de-structure it again when the performance is over. The prerequisite for this ability is to keep one’s self fundamentally unstructured, or, as Zhuangzi puts it, ‘empty’. This reading of Zhuangzian role-playing provides a fresh perspectives on ‘playing’ or ‘rambling’ as the central philosophical concept in the Zhuangzi. (shrink)

Zusammenfassung: Freundschaft ist ein wichtiges Thema der aristotelischen Moraltheorie. Aristoteles versteht unter Freundschaft die optimale Form der Beziehung, in der sich die Beteiligten gegenseitig schätzen und Wohltaten leisten. Im Rahmen seiner Freundschaftstheorie hat Aristoteles auch eine Auffassung der Freundschaft zwischen Eltern und Kindern entworfen. Im Vergleich zu seiner allge-meinen Freundschaftstheorie haben seine Ansätze zur Freundschaft zwischen Eltern und Kindern sowohl in der historischen als auch in der systematischen Forschung wenig Aufmerksamkeit gefunden. Das Ziel dieses Artikels ist es, die Auffassung dieser (...) speziellen Beziehung im Kontext seiner Moral- und Freundschaftstheorie darzustellen, zu interpretieren, aber auch weiterzuentwickeln bzw. zu vervollständi-gen. Zudem wird eine kritische Beurteilung sowie Korrektur einiger Aspekte dieser Theorie, insbesondere der Gläubiger-Schuldner-Auffassung der Eltern-Kinder-Beziehung, vorgenommen. Diese Auseinandersetzung mit Aristoteles’ Theorie führt zu einer klareren, systematischeren, aber auch attraktiveren und angemesseneren aristotelischen Theorie der Eltern-Kinder-Freundschaft, als sie in den Schriften des Aristoteles vorliegt. -/- Summary: Friendship (philia), the optimal form of a relationship, in which the friends love and do good things for each other, is an important theme of Aristotle’s ethics. In the framework of his friendship theory, Aristotle also outlined an account of the specific friendship emerging within the relationship between parents and their children. In comparison to his general theory of friendship, which has been widely discussed both by historians of philosophy and by ethicists, has this account received little at-tention. The objective of this article is to present and interpret, but also to develop and qualify, this account of parent-child friendship in the context of Aristotle’s general friendship theory. I shall also suggest that some aspects of this theory, in particular the debtor-creditor account of filial duties, need to be reassessed. This interpretation and discussion should yield a clearer, more systematic but also more attractive and adequate Aristotelian account of the optimal parent-children relationship than the one we find in the texts of Aristotle.

This article offers a philosophical reflection on ambivalences inherent in the notion of craft analogy in the thought of Zhuangzi and Aristotle. Does it make sense to establish the analogy between the structure of the good conduct of life and the structure of the successful performance of craft? In turn, what are the reasons for rejecting this analogy? This study shows that both philosophers had strong reasons both for their commitment to some aspects of the analogy and for its decisive (...) denial in other respects. However, their particular reasons for this ambiguous view on the craft analogy are remarkably different and even opposite. This divergence owes to some central cosmological and ontological commitments that undergird their theories of action; while Aristotle’s conception of the human world calls for conscious interference and deliberate action, Zhuangzi’s view is that ideal action should spontaneously follow the order immanent in all things.

For Aristotle, the happy life is the highest human good. But could even unhappy human lives have a grain of intrinsic goodness? Aristotle’s views about the value of the “mere living,” in contrast to the good living, have been neglected in the scholarship, despite his recurrent preoccupation with this question. Offering a close reading of a passage from Nicomachean Ethics IX.9, I argue that, for Aristotle, all human lives are intrinsically good by virtue of fully satisfying the definition, and thus (...) function, of their biological species. On the one hand, this rudimentary goodness is independent of whether the life is lived well or badly; on the other hand, it is ultimately outweighed by the badness inflicted on life by vice or extreme pain, so that unhappy lives are, all things considered, not worth choosing.

Insofar as living well is, for Aristotle, the ultimate end of human life, and insofar as our life comprises different activities (energeiai), the key prerequisite for living well is to rank and choose different activities according to their value. The objective of this article is to identify and discuss different considerations that determine the value of an activity in Aristotle's ethics. Focusing on selected passages from Nicomachean Ethics X, I argue that the structure of an activity's value displays considerable heterogeneity. (...) An activity can be good on account of its excellence, excellence-independent worthwhileness, as well as its continuity; these kinds of value do not necessarily entail each other, and they can even occur at each other's expense. This interpretation shifts the focus from the notion of virtue to the notion of activity, and thus opens up a fresh angle on Aristotle's: virtue or excellence is just one source of activity's value, alongside its worthwhileness and continuity.

The account of the best life for humans - i.e. a happy or flourishing life - and what it might consist of was the central theme of ancient ethics. But what does it take to have a life that, if not happy, is at least worth living, compared with being dead or never having come into life? This question was also much discussed in antiquity, and David Machek's book reconstructs, for the first time, philosophical engagements with the question (...) from Socrates to Plotinus. Machek's comprehensive book explores ancient views on a life worth living against a background of the pessimistic outlook on the human condition which was adopted by the Greek poets, and also shows the continuities and contrasts between the ancient perspective and modern philosophical debates about biomedical ethics and the ethics of procreation. His rich study of this relatively neglected theme offers a fresh and compelling narrative of ancient ethics. (shrink)

The article offers a critical analysis Plútarchovy moral theory in the work De Morali Virtue in its historical context and monitors while the more general philosophical question: what problems they must address philosophical theory of action that is motivated by the need to prove it is a substantial difference between reason and emotion as two sources of motivation, as Plutarch sought for it in this polemic against stoikům? In the first part, the author reconstructs Plútarchovo concept with special attention to (...) the way based on the Aristotelian framework and deviates from it. The second part shows that the rejection of Aristotle dealing with the relationship between cognitive and nerozumovou motivation and the adoption of some of the stoic nature of assumptions about human behavior theory Plútarchova slides towards stoic concept, against which it is directed. In conclusion the author based on several Plútarchových statement outlines an alternative and less vulnerable argumentative direction, which is used to Plutarch could go. (shrink)

This article attempts to provide an overview and discussion of Plutarch’s views in his Moralia about emotions and their relation to moral virtue and reason. By tracking different clusters of imagery – artisanal, zoological and botanic – that Plutarch uses in his essays to articulate the relationship between emotions and reason, it explores three philosophical perspectives on emotions: emotions of a virtuous person are likened to a well-shaped piece of material; to animals that need to be guided or reined in (...) by their master; and to wholesome plants in a garden. Each of these imageries is used to support a different account of moral virtue: virtue as the emotional disposition to feel moderately; virtue as the obedience of emotions to the commands of reason; and virtue as the absence of bad emotions and flourishing of the good ones. This analysis enables us to weigh the influences of major philosophers on Plutarch’s account, and to elucidate his commitment on both metriopatheia and apatheia. (shrink)

One of the most discussed parts of Cicero’s De Officiis is a theory (1.107–121), attributed by Cicero to a Stoic scholarch Panaetius, which attributes to all human beings four different roles (personae): our universal or rational nature; a set of our individual natural dispositions or traits; what we are by external circumstances; and the vocation or lifestyle that we freely choose. An appropriate action (officium) is to conform to constraints associated with one or more of these personae. Since Cicero does (...) not provide any clear model for weighing up or harmonizing constraints corresponding with different roles, scholars have worried that this theory is unstable and even conflicting. In particular, our individual inclinations often seem to pull against our reason or virtue. The aim of the first part of this article is to vindicate the cogency of the four-personae account by interpreting the relationship between the first and second persona in terms of the Stoic distinction between virtue and indifferent things. Our individual psychological dispositions are quasi-externals that are to be used well by our reason: they are first-order constraints on our reason, which itself is the second order constraint. Therefore, the first and second personae cannot directly conflict with each other. We are to use the individual dispositions well by choosing in the given circumstances (the third persona) a profession or a way of life (the fourth persona) that best suits these dispositions. In the second part, I am trying to show that this two-order psychological model of the self was adopted by other Stoics after Panaetius, particularly Epictetus and Seneca. All these thinkers distinguished between our universal psychological traits, i.e. our rationality, and individual natural psychological dispositions that are to be used well by our reason. I also provide an assessment of how this psychological model bears on recent debates in the scholarship about the Stoic philosophy of self, and suggest how it was motivated by developments in the Stoic ethics.

In this special issue, our goal is to ... show that the distinguished history of philosophical reflection on attention, insofar as the Western tradition is concerned, has at least some of its roots in Classical Greek and Roman philosophy. This is offered as a partial corrective to historical overviews of the Western discourse, which rarely reach further back than René Descartes. Furthermore, we wish to emphasize that ancient treatments of attention are especially concerned with its role in the context of (...) ethics and human agency. Even when they take their departure from an analysis of selective perceptual attention, their intention is not only to account for this phenomenon as part of a naturalistic science of the mind but also to motivate the view that the capacity to focus or to shift our attention is indispensable to human flourishing. Moral training is to a large extent conceived of as a matter of acquiring and sustaining the mental strength required for maintaining an attentive state of mind while resisting the interference of competing stimuli. -/- TABLE OF CONTENTS Pauliina Remes: From Natural Tendencies to Perceptual Interests and Motivation in Plato’s Timaeus Voula Tsouna: The Epicurean Notion of epibolê Katerina Ierodiakonou: The Stoic Provenance of the Notion of Prosochê Charles Brittain: A Stoic Ethics for Attention (Seneca Letter 56) Lenka Karfíková: Attention in Augustine.

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)

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.

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 the twenty-first century, the debate about life on other worlds is quickly changing from the realm of speculation to the domain of hard science. Within a few years, as a consequence of the rapid discovery by astronomers of planets around other stars, astronomers very likely will have discovered clear evidence of life beyond the Earth. Such a discovery of extraterrestrial life will change everything. Knowing the answer as to whether humanity has company in the universe will trigger one of (...) the greatest intellectual revolutions in history, not the least of which will be a challenge for at least some terrestrial religions. Which religions will handle the discovery of extraterrestrial life with ease and which will struggle to assimilate this new knowledge about our place in the universe? Some religions as currently practiced appear to only be viable on Earth. Other religions could be practiced on distant worlds but nevertheless identify both Earth as a place and humankind as a species of singular spiritual religious importance, while some religions could be practiced equally well anywhere in the universe by any sentient beings. Weintraub guides readers on an invigorating tour of the world's most widely practiced religions. It reveals what, if anything, each religion has to say about the possibility that extraterrestrial life exists and how, or if, a particular religion would work on other planets in distant parts of the universe.

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)

What is called ``orthodox'' quantum mechanics, as presented in standard foundational discussions, relies on two substantive assumptions --- the projection postulate and the eigenvalue-eigenvector link --- that do not in fact play any part in practical applications of quantum mechanics. I argue for this conclusion on a number of grounds, but primarily on the grounds that the projection postulate fails correctly to account for repeated, continuous and unsharp measurements and that the eigenvalue-eigenvector link implies that virtually all interesting properties are (...) maximally indefinite pretty much always. I present an alternative way of conceptualising quantum mechanics that does a better job of representing quantum mechanics as it is actually used, and in particular that eliminates use of either the projection postulate or the eigenvalue-eigenvector link, and I reformulate the measurement problem within this new presentation of orthodoxy.

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)

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.

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)
