Polarization is a topic of intense interest among social scientists, but there is significant disagreement regarding the character of the phenomenon and little understanding of underlying mechanics. A first problem, we argue, is that polarization appears in the literature as not one concept but many. In the first part of the article, we distinguish nine phenomena that may be considered polarization, with suggestions of appropriate measures for each. In the second part of the article, we apply this analysis to evaluate (...) the types of polarization generated by the three major families of computational models proposing specific mechanisms of opinion polarization.

ABSTRACT This article distinguishes nine senses of polarization and provides formal measures for each one to refine the methodology used to describe polarization in distributions of attitudes. Each distinct concept is explained through a definition, formal measures, examples, and references. We then apply these measures to GSS data regarding political views, opinions on abortion, and religiosity—topics described as revealing social polarization. Previous breakdowns of polarization include domain-specific assumptions and focus on a subset of the distribution’s features. This has conflated multiple, (...) independent features of attitude distributions. The current work aims to extract the distinct senses of polarization and demonstrate that by becoming clearer on these distinctions we can better focus our efforts on substantive issues in social phenomena.

A scientific community can be modeled as a collection of epistemic agents attempting to answer questions, in part by communicating about their hypotheses and results. We can treat the pathways of scientific communication as a network. When we do, it becomes clear that the interaction between the structure of the network and the nature of the question under investigation affects epistemic desiderata, including accuracy and speed to community consensus. Here we build on previous work, both our own and others’, in (...) order to get a firmer grasp on precisely which features of scientific communities interact with which features of scientific questions in order to influence epistemic outcomes.

Understanding the dynamics of information is crucial to many areas of research, both inside and outside of philosophy. Using computer simulations of three kinds of information, germs, genes, and memes, we show that the mechanism of information transfer often swamps network structure in terms of its effects on both the dynamics and the fitness of the information. This insight has both obvious and subtle implications for a number of questions in philosophy, including questions about the nature of information, whether there (...) is genetic information, and how to arrange scientific communities.

s for the Second Workshop on Implementing Machine Ethics.

The famous Cartesian Nicolas Malebranche (1638-1715) espoused the occasionalist doctrine that ‘there is only one true cause because there is only one true God; that the nature or power of each thing is nothing but the will of God; that all natural causes are not true causes but only occasional causes’ (LO, 448, original italics). One of Malebranche’s well-known arguments for occasionalism, known as, the ‘no necessary connection’ argument (or, NNC ) stems from the principle that ‘a true cause… is (...) one such that the mind perceives a necessary connection between it and its effect’ (LO, 450). The outline of this paper is as follows. I explicitly layout NNC and articulate some of its prima facie strengths (§1). I then critically discuss, what I take to be, the two main arguments against NNC of the Lee-Pyle interpretation (§2). The main conclusion from (§2) is that Malebranche did not abandon NNC in his later works given textual evidence from the Dialogues, contrary to the Lee-Pyle interpretation. In (§3) I discuss in what ways Suárez, Leibniz, Régis and Spinoza all accepted the main premise of NNC. Then, I rebut Steven Nadler’s influential and unchallenged criticism that Malebranche conflated causal and logical necessity, and provide a more accurate interpretation of Malebranche that only commits him to a partial reduction of causal to logical necessity (§4).

Advocates of cladistic parsimony methods have invoked the philosophy of Karl Popper in an attempt to argue for the superiority of those methods over phylogenetic methods based on Ronald Fisher's statistical principle of likelihood. We argue that the concept of likelihood in general, and its application to problems of phylogenetic inference in particular, are highly compatible with Popper's philosophy. Examination of Popper's writings reveals that his concept of corroboration is, in fact, based on likelihood. Moreover, because probabilistic assumptions are (...) necessary for calculating the probabilities that define Popper's corroboration, likelihood methods of phylogenetic inference—with their explicit probabilistic basis—are easily reconciled with his concept. In contrast, cladistic parsimony methods, at least as described by certain advocates of those methods, are less easily reconciled with Popper's concept of corroboration. If those methods are interpreted as lacking probabilistic assumptions, then they are incompatible with corroboration. Conversely, if parsimony methods are to be considered compatible with corroboration, then they must be interpreted as carrying implicit probabilistic assumptions. Thus, the non-probabilistic interpretation of cladistic parsimony favored by some advocates of those methods is contradicted by an attempt by the same authors to justify parsimony methods in terms of Popper's concept of corroboration. In addition to being compatible with Popperian corroboration, the likelihood approach to phylogenetic inference permits researchers to test the assumptions of their analytical methods (models) in a way that is consistent with Popper's ideas about the provisional nature of background knowledge.

As the premier early modern advocate of an Epicurean alternative to the prevailing neo-Scholastic framework of Aristotelianism, Pierre Gassendi promoted not only ancient but also innovative reasoning on behalf of atomism, probabilism, empiricism, psychological hedonism, social contractarianism, and a range of other stances associated with the philosophy of the Garden. Much commentary has focused on the extent to which Gassendi ‘baptizes’ Epicurean thought. Beyond this aspect of his Epicureanism are questions as to whether, and how, Gassendi is true to core (...) Epicurean thinking, and what he preserves and promotes as valuable to philosophical and natural investigations of his time. Indeed, much subsequent modern philosophy builds on or reacts to an Epicurean legacy bequeathed by Gassendi, comprising his adjustments to, constraints on, or corrections of, the canonical views. Yet, for all his amendments, he retains as a primary philosophical motivation the Epicurean goal of striving for ataraxia. In this, he signals his firm commitment to philosophy in the tradition of the canonical Epicurean views. And, as with Epicurus’ own notion, his account of the centrality of attaining tranquility directs us to a better understanding of our nature and that of the world around us; amenable, in Gassendi’s framework, to Christian thought and contemporary natural philosophical investigations.

This new and expanded edition of The Logic of Real Arguments explains a distinctive method for analysing and evaluating arguments. It discusses many examples, ranging from newspaper articles to extracts from classic texts, and from easy passages to much more difficult ones. It shows students how to use the question 'What argument or evidence would justify me in believing P?', and also how to deal with suppositional arguments beginning with the phrase 'Suppose that X were the case.' It aims to (...) help students to think critically about the kind of sustained, theoretical arguments which they commonly encounter in the course of their studies, including arguments about the natural world, about society, about policy, and about philosophy. It will be valuable for students and their teachers in a wide range of disciplines including philosophy, law and the social sciences. (shrink)

Can the Hippocratic and Judeo-Christian traditions be synthesized with contemporary thought about practical reason, virtue and community to provide real-life answers to the dilemmas of healthcare today? Bishop Anthony Fisher discusses conscience, relationships and law in relation to the modern-day controversies surrounding stem cell research, abortion, transplants, artificial feeding and euthanasia, using case studies to offer insight and illumination. What emerges is a reason-based bioethics for the twenty-first century; a bioethics that treats faith and reason with equal seriousness, that (...) shows the relevance of ancient wisdom to the complexities of modern healthcare scenarios and that offers new suggestions for social policy and regulation. Philosophical argument is complemented by Catholic theology and analysis of social and biomedical trends, to make this an auspicious example of a new generation of Catholic bioethical writing which has relevance for people of all faiths and none.

Value Sensitive Design (VSD) is an established method for integrating values into technical design. It has been applied to different technologies and, more recently, to artificial intelligence (AI). We argue that AI poses a number of challenges specific to VSD that require a somewhat modified VSD approach. Machine learning (ML), in particular, poses two challenges. First, humans may not understand how an AI system learns certain things. This requires paying attention to values such as transparency, explicability, and accountability. Second, ML (...) may lead to AI systems adapting in ways that ‘disembody’ the values embedded in them. To address this, we propose a threefold modified VSD approach: 1) integrating a known set of VSD principles (AI4SG) as design norms from which more specific design requirements can be derived; 2) distinguishing between values that are promoted and respected by the design to ensure outcomes that not only do no harm but also contribute to good; and 3) extending the VSD process to encompass the whole life cycle of an AI technology in order to monitor unintended value consequences and redesign as needed. We illustrate our VSD for AI approach with an example use case of a SARS-CoV-2 contact tracing app. (shrink)

Spinoza's Ethics is one of the most remarkable, important, and difficult books in the history of philosophy: a treatise simultaneously on metaphysics, knowledge, philosophical psychology, moral philosophy, and political philosophy. It presents, in Spinoza's famous 'geometric method', his radical views on God, Nature, the human being, and happiness. In this wide-ranging 2006 introduction to the work, Steven Nadler explains the doctrines and arguments of the Ethics, and shows why Spinoza's endlessly fascinating ideas may have been so troubling to his (...) contemporaries, as well as why they are still highly relevant today. He also examines the philosophical background to Spinoza's thought and the dialogues in which Spinoza was engaged - with his contemporaries, with ancient thinkers, and with his Jewish rationalist forebears. His book is written for the student reader but will also be of interest to specialists in early modern philosophy. (shrink)

The distinction between presentism and eternalism is usually sought in some formula like ‘Only presently existing things exist’ or ‘Past, present, and future events are equally real’. I argue that ambiguities in the copula prevent these slogans from distinguishing significant opposed positions. I suggest in addition that one can find a series of significant distinctions if one takes spacetime structure into account. These presentisms and eternalisms are not contradictory. They are complementary elements of a complete naturalistic philosophy of time.

In this paper, we review recent neuroimaging investigations of disorders of consciousness and different disciplines' understanding of consciousness itself. We consider potential tests of consciousness, their legal significance, and how they map onto broader themes in U.S. statutory law pertaining to advance directives and surrogate decision-making. In the process, we outline a taxonomy of themes to illustrate and clarify the variance in state-law definitions of consciousness. Finally, we discuss broader scientific, ethical, and legal issues associated with the advent of neuroimaging (...) for disorders of consciousness and conclude with policy recommendations that could help to mitigate confusion in this realm.

This paper provides an account of truth in interactive fiction. Interactive fiction allows the audience to make choices, resulting in many different possible fictions within each interactive fiction, unlike in literary fiction where there is just one. Adequately capturing this feature of interactive fiction requires us to address familiar issues regarding impossible fiction and the nature of time in fiction. Truth in interactive fiction thus requires a complex account to capture its multitude of fictions. It is argued that a full (...) account of truth in interactive fiction requires distinguishing two works for each interactive fiction, which contain distinct fictional truths. The actual work encompasses what is in fact represented as fictional (hence mistakes can be fictionally true in this work), whilst in the implied work, truth in fiction is governed by authorial intention, hence mistakes are not fictionally true. This dual account best captures our aesthetic evaluation of interactive fictions, for which we often need to distinguish how the work actually is from how it was intended to be. (shrink)

The potential for vaccines to prevent the spread of infectious diseases is crucial for vaccination policy and ethics. In this paper, I discuss recent evidence that the current COVID-19 vaccines have only a modest and short-lived effect on reducing SARS-CoV-2 transmission and argue that this has at least four important ethical implications. First, getting vaccinated against COVID-19 should be seen primarily as a self-protective choice for individuals. Second, moral condemnation of unvaccinated people for causing direct harm to others is unjustified. (...) Third, the case for a harm-based moral obligation to get vaccinated against COVID-19 is weak. Finally, and perhaps most significantly, coercive COVID-19 vaccination policies (e.g., measures that exclude unvaccinated people from society) cannot be directly justified by the harm principle.

Design for Values (DfV) philosophies are a series of design approaches that aim to incorporate human values into the early phases of technological design to direct innovation into beneficial outcomes. The difficulty and necessity of directing advantageous futures for transformative technologies through the application and adoption of value-based design approaches are apparent. However, questions of whose values to design are of critical importance. DfV philosophies typically aim to enrol the stakeholders who may be affected by the emergence of such a (...) technology. However, regardless of which design approach is adopted, all enrolled stakeholders are human ones who propose human values. Contemporary scholarship on metahumanisms, particularly those on posthumanism, have decentred the human from its traditionally privileged position among other forms of life. Arguments that the humanist position is not (and has never been) tenable are persuasive. As such, scholarship has begun to provide a more encompassing ontology for the investigation of nonhuman values. Given the potentially transformative nature of future technologies as relates to the earth and its many assemblages, it is clear that the value investigations of these design approaches fail to account for all relevant stakeholders (i.e., nonhuman animals). This paper has two primary objectives: (1) to argue for the cogency of a posthuman ethics in the design of technologies; and (2) to describe how existing DfV approaches can begin to envision principled and methodological ways of incorporating non-human values into design. To do this, the paper provides a rudimentary outline of what constitutes DfV approaches. It then takes up a unique design approach called Value Sensitive Design (VSD) as an illustrative example. Out of all the other DfV frameworks, VSD most clearly illustrates a principled approach to the integration of values in design. (shrink)

Steven Crowell has been for many years a leading voice in debates on twentieth-century European philosophy. This volume presents thirteen recent essays that together provide a systematic account of the relation between meaningful experience and responsiveness to norms. They argue for a new understanding of the philosophical importance of phenomenology, taking the work of Husserl and Heidegger as exemplary, and introducing a conception of phenomenology broad enough to encompass the practices of both philosophers. Crowell discusses Husserl's analyses of first-person (...) authority, the semantics of conscious experience, the structure of perceptual content, and the embodied subject, and shows how Heidegger's interpretation of the self addresses problems in Husserl's approach to the normative structure of meaning. His volume will be valuable for upper-level students and scholars interested in phenomenological approaches to philosophical questions in both the European and the analytic traditions. (shrink)

Emerging technologies such as cloud computing, augmented and virtual reality, artificial intelligence and robotics, among others, are transforming the field of manufacturing and industry as a whole in unprecedent ways. This fourth industrial revolution is consequentially changing how operators that have been crucial to industry success go about their practices in industrial environments. This short paper briefly introduces the notion of the Operator 4.0 as well as how this novel way of conceptualizing the human operator necessarily implicates human values in (...) the technologies that constitute it. Similarly, the design methodology known as value sensitive design (VSD) is drawn upon to discuss how these Operator 4.0 technologies can be design for human values and, conversely, how a potential value-sensitive Operator 4.0 can be used to strengthen the VSD methodology in developing novel technologies.

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we (...) express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed.

The last decade has witnessed the mass distribution and adoption of smart home systems and devices powered by artificial intelligence systems ranging from household appliances like fridges and toasters to more background systems such as air and water quality controllers. The pervasiveness of these sociotechnical systems makes analyzing their ethical implications necessary during the design phases of these devices to ensure not only sociotechnical resilience, but to design them for human values in mind and thus preserve meaningful human control over (...) them. This paper engages in a conceptual investigations of how meaningful human control over smart home devices can be attained through design. The value sensitive design (VSD) approach is proposed as a way of attaining this level of control. In the proposed framework, values are identified and defined, stakeholder groups are investigated and brought into the design process and the technical constraints of the technologies in question are considered. The paper concludes with some initial examples that illustrate a more adoptable way forward for both ethicists and engineers of smart home devices. (shrink)

Autonomous weapons systems (AWS), sometimes referred to as “killer robots”, are receiving evermore attention, both in public discourse as well as by scholars and policymakers. Much of this interest is connected with emerging ethical and legal problems linked to increasing autonomy in weapons systems, but there is a general underappreciation for the ways in which existing law might impact on these new technologies. In this paper, we argue that as AWS become more sophisticated and increasingly more capable than flesh-and-blood soldiers, (...) it will increasingly be the case that such soldiers are “in the power” of those AWS which fight against them. This implies that such soldiers ought to be considered hors de combat, and not targeted. In arguing for this point, we draw out a broader conclusion regarding hors de combat status, namely that it must be viewed contextually, with close reference to the capabilities of combatants on both sides of any discreet engagement. Given this point, and the fact that AWS may come in many shapes and sizes, and can be made for many different missions, we argue that each particular AWS will likely need its own standard for when enemy soldiers are deemed hors de combat. We conclude by examining how these nuanced views of hors de combat status might impact on meaningful human control of AWS. (shrink)

Baruch Spinoza (1632–1677) was one of the most important philosophers of all time; he was also arguably the most radical and controversial. This was the first complete biography of Spinoza in any language and is based on detailed archival research. More than simply recounting the story of Spinoza's life, the book takes the reader right into the heart of Jewish Amsterdam in the seventeenth century and, with Spinoza's exile from Judaism, right into the midst of the tumultuous political, social, intellectual (...) and religious world of the young Dutch Republic. Though the book will be an invaluable resource for philosophers, historians, and scholars of Jewish thought, it has been written for any member of the general reading public with a serious interest in philosophy, Jewish history, seventeenth-century European history, and the culture of the Dutch Golden Age. Spinoza: A Life has recently been awarded the Koret Jewish Book Award. (shrink)

What are the inherent claims that lie at the core of religion? Which of them are defensible by reason, and which are not? Potential answers to these questions and more, from influential philosophers past and present, may be found in this short book edited by Steven M. Cahn. Featuring fifty-two classic and contemporary readings, Exploring Philosophy of Religion: Text and Readings is a topically-organized anthology that presents broad coverage of seven major areas in the philosophy of religion - the (...) concept of God, the existence of God, religious language, miracles and mysticism, belief in God, resurrection and immortality, and religious pluralism - in a clear and accessible format. With guiding introductory material from Professor Cahn, each of the readings has been carefully selected and edited for maximum clarity and comprehensiveness; only the most essential material is included. To further foster understanding, the text also features an appendix consisting of Professor Cahn's monograph, God, Reason, and Religion, which provides a synthesis and interpretation of the crucial issues raised throughout the readings.

Background: Recent research demonstrates that people sometimes make different medical decisions for others than they would make for themselves. This finding is particularly relevant to end-of-life decisions, which are often made by surrogates and require a trade-off between prolonging life and maintaining quality of life. We examine the impact of decision role, patient age, decision maker age and multiple individual differences on these treatment decisions. Methods: Participants read a scenario about a terminally ill cancer patient faced with a choice between (...) an aggressive chemotherapy regimen that will extend life by two years and palliative treatments to control discomfort for one remaining month. Participants were randomly assigned to one of three decision roles (patient, physician, or an abstract other) and the scenario randomly varied whether the patient was described as 25 or 65-years old. Results: When deciding for a 65-year old patient, approximately 60% of participants selected aggressive chemotherapy regardless of decision role. When deciding for a 25-year old patient, however, participants were more likely to select chemotherapy for a patient (physician role) or another person (abstract other) than for themselves (70%, 67%, and 59%, respectively). In addition, confidence that powerful others (eg, physicians) control one’s health, as well as respondents’ age and race, consistently predicted treatment choices. Conclusions: Patient age appears to influence medical decisions made for others but not those that we make for ourselves. These findings may help to explain the discord that often occurs when younger cancer patients refuse life-extending treatments. (shrink)

This is the first detailed study to explore the little-understood notions of "knowing who someone is," "knowing a person's identity," and related locutions. It locates these notions within the context of a general theory of believing and a semantical theory of belief- and knowledge-ascriptions.The books's main contention is that what one knows, when one knows who someone is, is not normally an identity in the numerical sense of "a = b," but rather a certain sort of predication to know who (...) someone is is just to know that that person is F, where "F" is a predicate that is "important," in a technical sense defined by the authors, for the purposes determined by context. Their book offers a rigorous formal semantics for ascriptions of knowing and of knowing-who in particular, solving such well-known problems and paradoxes as Kripke's Puzzle, and Quines difficulties with de re belief, along the way.The authors apply their analysis to each of several important issues in philosophy of language, philosophy of mind, and ethical theory in which the previously unexamined notion of "knowing who" has loomed large-the mechanics of linguistic referring, the foundations of epistemic logic, problems of self-knowledge and self-regarding belief, universalizability and "Golden Rule" arguments in ethics, and moral "personalism" versus "impartialism."Stephen Boër is Professor of Philosophy at the Ohio State University.

Released in 1984, Steven E. Rhoads' classic was considered by many to be among the best introductions to the economic way of thinking and its applications. This anniversary edition has been updated to account for political and economic developments - from the greater interest in redistributing income and the ascendancy of behaviorism to the Trump presidency. Rhoads explores opportunity cost, marginalism, and economic incentives and explains why mainstream economists - even those well to the left - still value free (...) markets. He critiques economics for its unbalanced emphasis on narrow self-interest as controlling motive and route to happiness, highlighting philosophers and positive psychologists' findings that happiness is far more dependent on friends and family than on income or wealth. This thought-provoking tour of the economist's mind is a must read for our times, providing a clear, lively, non-technical insight into how economists think and why they shouldn't be ignored. (shrink)
