In the philosophy of climate science, debate surrounding the issue of variety of evidence has mostly taken the form of attempting to connect these issues in climate science and climate modeling with philosophical accounts of what has come to be known as “robustness analysis.” I argue that an “explanatory” conception of robustness is the best candidate for understanding variety of evidence in climate science. I apply the analysis to both examples of model agreement, as well at to the convergence of (...) evidence from both model and non-model sources. (shrink)

In computer simulations of physical systems, the construction of models is guided, but not determined, by theory. At the same time simulations models are often constructed precisely because data are sparse. They are meant to replace experiments and observations as sources of data about the world; hence they cannot be evaluated simply by being compared to the world. So what can be the source of credibility for simulation models? I argue that the credibility of a simulation model comes not only (...) from the credentials supplied to it by the governing theory, but also from the antecedently established credentials of the model building techniques employed by the simulationists. In other words, there are certain sorts of model building techniques which are taken, in and of themselves, to be reliable. Some of these model building techniques, moreover, incorporate what are sometimes called “falsifications.” These are contrary-to-fact principles that are included in a simulation model and whose inclusion is taken to increase the reliability of the results. The example of a falsification that I consider, called artificial viscosity, is in widespread use in computational fluid dynamics. Artificial viscosity, I argue, is a principle that is successfully and reliably used across a wide domain of fluid dynamical applications, but it does not offer even an approximately “realistic” or true account of fluids. Artificial viscosity, therefore, is a counter-example to the principle that success implies truth – a principle at the foundation of scientific realism. It is an example of reliability without truth.

This book offers a state-of-the-art introduction to the basic techniques and results of neighborhood semantics for modal logic. In addition to presenting the relevant technical background, it highlights both the pitfalls and potential uses of neighborhood models – an interesting class of mathematical structures that were originally introduced to provide a semantics for weak systems of modal logic. In addition, the book discusses a broad range of topics, including standard modal logic results ; bisimulations for neighborhood models and other model-theoretic (...) constructions; comparisons with other semantics for modal logic ; neighborhood semantics for first-order modal logic, applications in game theory ; applications in epistemic logic ; and non-normal modal logics with dynamic modalities. The book can be used as the primary text for seminars on philosophical logic focused on non-normal modal logics; as a supplemental text for courses on modal logic, logic in AI, or philosophical logic ; or as the primary source for researchers interested in learning about the uses of neighborhood semantics in philosophical logic and game theory.

In a large and impressive body of published work, Quayshawn Spencer has meticulously articulated and defended a metaphysical project aimed at resuscitating a biological conception of race—one free from many of the pitfalls of biological essentialism. If successful, such a project would be highly rewarding, since it would provide a compelling response to philosophers who have denied the genuine existence of race while avoiding the very dangers that they sought to avoid. The aim of this paper is to subject those (...) moves to careful scrutiny and thereby appraise the prospects for a new biologism about race. (shrink)

We use Nietzsche’s On the Genealogy of Morality as a touchstone for comprehending Trump’s appeal and victory. Following Nietzsche’s concerns, the most noteworthy puzzle is that of Trump’s peculiar popularity, especially given his impolitic statements and policy proposals that often appear in tension with the interests of his voter base. While Nietzsche’s discussions of power and resentment would seem obvious starting points to examine the success of Trump and Trumpism, we contend that these provide largely superficial and, at best, incomplete (...) explanations. Instead, informed by Nietzsche’s moral psychology, we analyze Trump’s strategy in the context of the instinctual need for self-preservation. Trump’s amplification of this need through his rhetoric and cultivation of negative emotions, including resentment, has led to a revaluation that diminishes humanity. We conclude by drawing out the implications of Nietzsche’s view, revealing a forceful Nietzschean critique of Trump’s methods and values. (shrink)

Focusing on the breakthrough field of molecular engineering--a new technology enabling scientists to build tiny machines atom by atom--the author offers projections on how this technological revolution will affect the future of computer science, space travel, medicine, and manufacturing.

This book uncovers a logical structure that is common to many, if not all, of the kinds posited by scientific taxonomies. Specification relations, such as those holding between determinates and determinables (determination), are central to this logical investigation of kinds. The species–genus relation is a familiar specification relation for substantival kinds, but this book focuses on adjectival kinds—whose instances are properties—instead. Determination relations are then used to structure kinds at the same level of abstraction into property spaces, which in turn (...) leads to a theory for individuating properties (tropes). These determination relations are contrasted with realization relations, the latter being the favored way of understanding the connection between the mental and the physical. Particular attention is given to the distinction between multiple realizability and multiple determination, and it is argued that determination and realization are mutually exclusive. The claim that multiple realizability entails various senses of autonomy is defended from various reductionist challenges. These theories of determination and realization then provide general standards for establishing the autonomy of the special sciences or, conversely, their reduction. (shrink)

Violations of the Bell inequalities in EPR-Bohm type experiments have set the literature on the metaphysics of microscopic systems to flirting with some sort of metaphysical holism regarding spatially separated, entangled systems. The rationale for this behavior comes in two parts. The first part relies on the proof, due to Jon Jarrett [2] that the experimentally observed violations of the Bell inequalities entail violations of the conjunction of two probabilistic constraints. Jarrett called these two constraints locality and completeness. We prefer (...) the terminology of locality and factorizability.[3] The first part of the rationale for metaphysical holism urges that only Jarrett’s locality allows for “peaceful coexistence” between any model of EPR-Bohm type experiments and special relativity. Factorizability, it is suggested, must be jettisoned. (shrink)

Self-deception poses longstanding and fascinating paradoxes. Philosophers have questioned whether, and how, self-deception is even possible; evolutionary theorists have debated whether it is adaptive. For Sigmund Freud self-deception was a fundamental key to understanding the unconscious, and from The Bible to The Great Gatsby literature abounds with characters renowned for their self-deception. But what exactly is self-deception? Why is it so puzzling? How is it performed? And is it harmful? ...

In his original semantics for counterfactuals, David Lewis presupposed that the ordering of worlds relevant to the evaluation of a counterfactual admitted no incomparability between worlds. He later came to abandon this assumption. But the approach to incomparability he endorsed makes counterintuitive predictions about a class of examples circumscribed in this paper. The same underlying problem is present in the theories of modals and conditionals developed by Bas van Fraassen, Frank Veltman, and Angelika Kratzer. I show how to reformulate all (...) these theories in terms of lower bounds on partial preorders, conceived of as maximal antichains, and I show that treating lower bounds as cutsets does strictly better at capturing our intuitions about the semantics of modals, counterfactuals, and deontic conditionals.

This paper presents and discusses a range of counterexamples to the common view that quantifiers cannot take scope over epistemic modals. Some of the counterexamples raise problems for ‘force modifier’ theories of epistemic modals. Some of the counterexamples raise problems for Robert Stalnaker’s theory of counterfactuals, according to which a special kind of epistemic modal must be able to scope over a whole counterfactual. Finally, some of the counterexamples suggest that David Lewis must countenance ‘would’ counterfactuals in which a covert (...) ‘would’ scopes over the whole consequent of the counterfactual, including an overt ‘might.’.

In some contexts, not saying S generates a conversational implicature: that the speaker didn’t have sufficient reason, all things considered, to say S. I call this an omissive implicature. Standard ways of thinking about conversational implicature make the importance and even the existence of omissive implicatures somewhat surprising. But I argue that there is no principled reason to deny that there are such implicatures, and that they help explain a range of important phenomena. This paper focuses on the roles omissive (...) implicatures play in Quantity implicatures—in particular, in solving the symmetry problem for scalar implicatures—and on the political and social importance of omissions where apologies, objections, or other communicative acts are expected or warranted.

Written in debate format, this book covers developing fields such as social cognition, as well as classic areas such as memory, learning, perception and categorization. The links between emotion and memory, learning, perception, categorization, social judgements, and behavior are addressed.

In his latest book, Eric Scerri presents a completely original account of the nature of scientific progress. It consists of a holistic and unified approach in which science is seen as a living and evolving single organism. Instead of scientific revolutions featuring exceptionally gifted individuals, Scerri argues that the "little people" contribute as much as the "heroes" of science. To do this he examines seven case studies of virtually unknown chemists and physicists in the early 20th century quest to (...) discover the structure of the atom. They include the amateur scientist Anton van den Broek who pioneered the notion of atomic number as well as Edmund Stoner a then physics graduate student who provided the seed for Pauli's Exclusion Principle. Another case is the physicist John Nicholson who is virtually unknown and yet was the first to propose the notion of quantization of angular momentum that was soon put to good use by Niels Bohr. Instead of focusing on the logic and rationality of science, Scerri elevates the role of trial and error and multiple discovery and moves beyond the notion of scientific developments being right or wrong. While criticizing Thomas Kuhn's notion of scientific revolutions he agrees with Kuhn that science is not drawn towards an external truth but is rather driven from within. The book will enliven the long-standing debate on the nature of science, which has increasingly shied away from the big question of "what is science?". (shrink)

Uncertainty and affect are fundamental and interrelated aspects of the human condition. Uncertainty is often associated with negative affect, but in some circumstances it is associated with positive affect. In this paper, we review different explanations for the varying relationship between uncertainty and affect. We identify “mental simulation” as a key process that links uncertainty to affective states. We suggest that people have a propensity to simulate negative outcomes, which results in a propensity towards negative affective responses to uncertainty. We (...) also propose the existence of several important moderators of this process, including context and individual differences such as uncertainty tolerance, as well as emotion regulation strategies. Finally, we highlight important knowledge gaps and promising areas for future research, both empirical and conceptual, to further elucidate the relationship between uncertainty and affect. (shrink)

The law of desire has been proposed in several forms, but its essential claim is that agents always act on their strongest proximal action motivation. This law has threatening consequences for human freedom, insofar as it greatly limits agents’ ability to do otherwise given their motivational state. It has proven difficult to formulate a version that escapes counterexamples and some categorically deny its truth. Noticeable by its absence in the literature is any attempt to provide an argument for the law (...) of desire – I propose such an argument here. It is noted that Sripada's “divided mind” theory of willpower provides a counterexample to the version of the law of desire my argument defends, but I note that a reformulated version of the law of desire survives this critique. I conclude that there is a serious case for the law of desire, and note the broader implications of this. (shrink)

Recently, Doolittle and Inkpen formulated a thought provoking theory, asserting that evolution by natural selection was responsible for the sideways evolution of two radically different kinds of selective units (also called Domains). The former entities, termed singers, correspond to the usual objects studied by evolutionary biologists (gene, genomes, individuals, species, etc.), whereas the later, termed songs, correspond to re‐produced biological and ecosystemic functions, processes, information, and memes. Singers perform songs through selected patterns of interactions, meaning that a wealth of critical (...) phenomena might receive novel evolutionary explanations. However, this theory did not provide an empirical approach to study evolution in such a broadened context. Here, we show that analyzing songs and singers, using patterns of interaction networks as a common ontology for both, offers a novel, actionable, inclusive and mathematical way to analyze not only the re‐production but also the evolution and fitness of biological and ecosystemic interconnected processes.

Many philosophical theories make comparisons between objects, events, states of affairs, worlds, or systems, and many such theories deliver plausible verdicts only if some of the elements they compare are ranked as ‘best.’ When the relevant ordering does not have such ‘best’ or ‘tied for best’ elements the theory wrongly falls silent or gives badly counterintuitive results. This paper develops ordering supervaluationism---a very general technique that allows any such theory to handle these problematic cases. Just as ordinary supervaluation helps us (...) save and generalize ‘uniqueness assuming’ theories, ordering supervaluationism helps us save and generalize ‘limit assuming’ theories. With so many otherwise attractive limit assuming theories, this is a sensible, methodologically conservative approach. (shrink)

What is group well-being? There is, as of yet, shockingly little philosophical literature explicitly aiming to answer this question. This essay sketches some of the logical space of possible answers, and nudges us to seriously consider certain overlooked options. There are several importantly different ways the well-being of a collective or a group could be related to the well-being of the individuals who constitute it: 1) eliminativism, 2) functionalism, 3) partialism, or 4) the independent view. If the relation between individual (...) and collective well-being is either functional or partial, then we face a further question: What is the direction of constitutive dependence? Does the well-being of a group depend upon the well-being of the well-being of the individuals who compose it, or does the well-being of an individual depend upon the well-being of the groups to which they belong? Or both? These questions raise some puzzles that I begin to resolve. I conclude that there might be a wide variety of ways the well-being of a collective obtains, only some of which are related to the well-being of the individuals who are its members. In the end, I hope to vindicate the thought that an injury to one is an injury to all. (shrink)

Scientific modelling is a value-laden process: the decisions involved can seldom be made using 'scientific' criteria alone, but rather draw on social and ethical values. In this paper, we draw on a body of philosophical literature to analyze a COVID-19 vaccination model, presenting a case study of social and ethical value judgments in health-oriented modelling. This case study urges us to make value judgments in health-oriented models explicit and interpretable by non-experts and to invite public involvement in making them.

We propose that doping be legalized under medical supervision. First, we discuss two motivations for allowing medically supervised doping. We reject the ‘compromised choice/harm minimization’ motivation as unlikely to win the support of athletes. We agree that it could lead to an arms race. Instead, we favor full acceptance of doping under medical supervision and answer Reid’s spirit of sport objection to medical manipulation. After presenting a set of guiding principles, we use them to answer the arms race objection and (...) rebut one of the most prominent objections in the literature about the safety of medically supervised doping, the game-theoretic objection.

It seems that we can know moral truths. We are also rather reluctant to defer to moral testimony. But it’s not obvious how moral cognitivism is compatible with pessimism about moral testimony. If moral truths are knowable, shouldn’t it be possible for others to know moral truths you don’t know, so that it is wise for you to defer to what they say? Or, alternatively, if it’s always reasonable to refuse to defer to the wisest among us, doesn’t this show (...) that morality is not genuinely cognitive? There is a tension in our commonsense moral epistemology. In this chapter I (a) explicate this tension, (b) criticize how others have attempted to resolve it, and finally (c) explain how Rossian deontology helps us see that the tension is only apparent: morality is indeed knowable, despite the fact that it is usually wise to refuse to defer to moral testimony.

"The king is dead. Long live the king!" In early modern Europe, the king's body was literally sovereign—and the right to rule was immediately transferrable to the next monarch in line upon the king's death. In The Royal Remains, Eric L. Santner argues that the "carnal" dimension of the structures and dynamics of sovereignty hasn't disappeared from politics. Instead, it migrated to a new location—the life of the people—where something royal continues to linger in the way we obsessively track (...) and measure the vicissitudes of our flesh. Santner demonstrates the ways in which democratic societies have continued many of the rituals and practices associated with kingship in displaced, distorted, and usually, unrecognizable forms. He proposes that those strange mental activities Freud first lumped under the category of the unconscious—which often manifest themselves in peculiar physical ways—are really the uncanny second life of these "royal remains," now animated in the body politic of modern neurotic subjects. Pairing Freud with Kafka, Carl Schmitt with Hugo von Hofmannsthal,and Ernst Kantorowicz with Rainer Maria Rilke, Santner generates brilliant readings of multiple texts and traditions of thought en route to reconsidering the sovereign imaginary. Ultimately, The Royal Remains locates much of modernity—from biopolitical controversies to modernist literary experiments—in this transition from subjecthood to secular citizenship. This major new work will make a bold and original contribution to discussions of politics, psychoanalysis, and modern art and literature. (shrink)

In this philosophy classic, which was first published in 1951, E. R. Dodds takes on the traditional view of Greek culture as a triumph of rationalism. Using the analytical tools of modern anthropology and psychology, Dodds asks, "Why should we attribute to the ancient Greeks an immunity from 'primitive' modes of thought which we do not find in any society open to our direct observation?" Praised by reviewers as "an event in modern Greek scholarship" and "a book which it would (...) be difficult to over-praise," _The Greeks and the Irrational _was Volume 25 of the Sather Classical Lectures series.

When proponents of cognitive externalism (CE) turn to empirical studies in cognitive science to put the framework to use and to assess its explanatory success, they typically refer to perception, memory, or motor coordination. In contrast, not much has been said about reasoning. One promising avenue to explore in this respect is the theory of bounded rationality (BR). To clarify the relationship between CE and BR, we criticize Andy Clark's understanding of BR, as well as his claim that BR does (...) not fit his version of CE. We then propose and defend a version of CE—“scaffolded cognition”—that is not committed to constitutive claims about the mind, but still differs from mainstream internalism. Finally, we analyze BR from our own CE perspective, thereby clarifying its vague appeals to the environment, and argue that cognitive internalism cannot explain important aspects of the BR program.

Individuals who become ill as a result of personal lifestyle choices often shift the monetary costs of their healthcare needs to the taxpaying public or to fellow members of a private insurance pool. Some argue that policies permitting such cost shifting are unfair. Arguments for this view may seem to draw support from luck egalitarian accounts of distributive justice. This essay argues that the luck egalitarian framework provides no such support. To allocate healthcare costs on the basis of personal responsibility (...) would arbitrarily and publicly burden socially detectable risk-takers while undetectable risk-takers continue to get a free ride. That problem is unavoidable even on the assumption that distributive institutions outside the healthcare sector are fully just. In actual, farfrom-just societies, imposing personal liability for the costs of voluntary risk taking would be wrong for an additional reason. Doing so would tend to magnify existing distributive injustices. These conclusions draw attention to two common ‘moral fallacies of the second best’ that can arise when applying ideal normative theory to matters of institutional design and in real-world policy contexts.

A collection of quirky, entertaining, and reader-friendly short pieces on philosophical topics that range from a theory of jerks to the ethics of ethicists. Have you ever wondered about why some people are jerks? Asked whether your driverless car should kill you so that others may live? Found a robot adorable? Considered the ethics of professional ethicists? Reflected on the philosophy of hair? In this engaging, entertaining, and enlightening book, Eric Schwitzgebel turns a philosopher's eye on these and other (...) burning questions. In a series of quirky and accessible short pieces that cover a mind-boggling variety of philosophical topics, Schwitzgebel offers incisive takes on matters both small and large. A common theme might be the ragged edge of the human intellect, where moral or philosophical reflection begins to turn against itself, lost among doubts and improbable conclusions. The history of philosophy is humbling when we see how badly wrong previous thinkers have been, despite their intellectual skills and confidence. Some of the texts resist thematic categorization—thoughts on the philosophical implications of dreidels, the diminishing offensiveness of the most profane profanity, and fatherly optimism—but are no less interesting. Schwitzgebel has selected these pieces from the more than one thousand that have appeared since 2006 in various publications and on his popular blog, The Splintered Mind, revising and updating them for this book. Philosophy has never been this much fun. (shrink)

International borders concentrate opportunities in some societies while limiting them in others. Borders also prevent those in the less favored societies from gaining access to opportunities available in the more favored ones. Both distributive effects of borders are treated here within a comprehensive framework. I argue that each state should have broad discretion under international law to grant or deny entry to immigration seekers; but more favored countries that find themselves under immigration pressure should be legally obligated to fund development (...) assistance for countries that generate immigration pressure. Funding should be subject to conditions of fair and effective use in recipient countries, and should aim at a near-term target of immigration-pressure equilibrium. Equilibrium obtains between two countries when, given appropriate background circumstances, the same proportion of individuals in each manifests a preference to migrate to the other. If meeting the equilibrium target in the short term would be to the long-term disadvantage of the worst-off countries, then a Pareto-superior alternative target supersedes. It mandates development assistance at the level that yields the most favorable human development projections for the worstoff countries. An implementable set of institutions is described that can achieve the equilibrium goal in the long term without unduly sacrificing other important ends, including economic growth, political stability, cultural integrity, the political autonomy of distinct societies, and their proper accountability for policy choices. Key Words: global justice • immigration • borders • development • distributive justice • development assistance • equality • international law • cosmopolitanism. (shrink)

It is sometimes claimed that formalism and the logical incompatibility thesis together imply that fouls cannot be part of the game. Some philosophers think this proves that therefore strategic fouls are always morally wrong, but other philosophers think this result undermines formalism itself, since strategic fouls clearly are part of the game and are at least sometimes morally permissible. I show that formalism in fact does accommodate strategic fouls and that it is neutral about whether strategic fouls are morally permissible (...) or not. (shrink)

In this collection of new and previously published essays, noted philosopher Eric Schliesser offers new interpretations of the signifance of Isaac Newton's metaphysics on his physics and the subsequent development of philosophy more broadly. In particular, he explores the rich resonances between Newton's and Spinoza's metaphysics. The volume includes a substantive introduction, new chapters on Newton's modal metaphysics and his theology, and two postscripts in whichSchliesser responds to some of his most important critics, including Katherine Brading, Andrew Janiak, Hylarie (...) Kochiras, Steffen Ducheyne, and Adwait Parker. The collection provides new and varied analyses on familiar focuses of Newton's work, adding important perspectives to the recent revival ofinterest in Spinoza's metaphysics. (shrink)

Bernard Williams argued that philosophers should pay more attention to the role thick ethical concepts play in our moral thinking, and, separately, that all reasons for action depend in the first place upon the agent's pre-exisitng motives. Here I argue that these two views are in tension. Much like the standard examples of thick ethical concepts, the concept REASONABLE is likewise thick, and the features of the world that guide its correct use have much less to do with the agent's (...) pre-existing motives than internalism about reasons for action maintains.

Taking as the focus of enquiry the engagements of Félix Guattari with Marcel Duchamp, namely, those rare passages in Schizoanalytic Cartographies and Chaosmosis, the question of the encounter is posed in the field of the sign, but of a sign ‘destructured’ (as Duchamp du signe), in the sense also that Guattari started by destructuring Lacan (from Psychoanalysis and Transversality to Anti-Oedipus). Introduced by the relationships between Guattari and Foucault to better play in between the early and the late Guattari, Guattari’s (...) key insight into the Bottle Rack readymade as an existential function is critically discussed from a reopening to enunciation through the ‘Duchamp effect’. If the latter seems to privilege language contrary to Guattari’s own semiotics, it is to derail it as a machinic unconscious. Duchamp’s writings on his readymades and other machinations are analysed, with the role of Raymond Roussel for Duchamp (and Deleuze-Guattari via Foucault), as well as the implications of a trans-Duchamp, his alter-ego Rrose Sélavy, as an opening to a machinic alterity undoing and queering gender binarity and phallic centricity, recovering the singularity of the bachelor machine and its rupture of subjectivation. The article shows how it could be transversally returned to the very middle of the Guattarian trajectory. (shrink)
