Inspired by recent breakthroughs in predictive modeling, practitioners in both industry and government have turned to machine learning with hopes of operationalizing predictions to drive automated decisions. Unfortunately, many social desiderata concerning consequential decisions, such as justice or fairness, have no natural formulation within a purely predictive framework. In efforts to mitigate these problems, researchers have proposed a variety of metrics for quantifying deviations from various statistical parities that we might expect to observe in a fair world and offered a (...) variety of algorithms in attempts to satisfy subsets of these parities or to trade o the degree to which they are satised against utility. In this paper, we connect this approach to fair machine learning to the literature on ideal and non-ideal methodological approaches in political philosophy. The ideal approach requires positing the principles according to which a just world would operate. In the most straightforward application of ideal theory, one supports a proposed policy by arguing that it closes a discrepancy between the real and the perfectly just world. However, by failing to account for the mechanisms by which our non-ideal world arose, the responsibilities of various decision-makers, and the impacts of proposed policies, naive applications of ideal thinking can lead to misguided interventions. In this paper, we demonstrate a connection between the fair machine learning literature and the ideal approach in political philosophy, and argue that the increasingly apparent shortcomings of proposed fair machine learning algorithms reflect broader troubles faced by the ideal approach. We conclude with a critical discussion of the harms of misguided solutions, a reinterpretation of impossibility results, and directions for future research. (shrink)

Machine learning algorithms are increasingly used to shape high-stake allocations, sparking research efforts to orient algorithm design towards ideals of justice and fairness. In this research on algorithmic fairness, normative theorizing has primarily focused on identification of “ideally fair” target states. In this paper, we argue that this preoccupation with target states in abstraction from the situated dynamics of deployment is misguided. We propose a framework that takes dynamic trajectories as direct objects of moral appraisal, highlighting three respects in which (...) such trajectories can be subject to evaluation in relation to their temporal dynamics, robustness, and representation.

Typically, fair machine learning research focuses on a single decision maker and assumes that the underlying population is stationary. However, many of the critical domains motivating this work are characterized by competitive marketplaces with many decision makers. Realistically, we might expect only a subset of them to adopt any non-compulsory fairness-conscious policy, a situation that political philosophers call partial compliance. This possibility raises important questions: how does partial compliance and the consequent strategic behavior of decision subjects affect the allocation outcomes? (...) If k% of employers were to voluntarily adopt a fairness-promoting intervention, should we expect k% progress (in aggregate) towards the benefits of universal adoption, or will the dynamics of partial compliance wash out the hoped-for benefits? How might adopting a global (versus local) perspective impact the conclusions of an auditor? In this paper, we propose a simple model of an employment market, leveraging simulation as a tool to explore the impact of both interaction effects and incentive effects on outcomes and auditing metrics. Our key findings are that at equilibrium: (1) partial compliance by k% of employers can result in far less than proportional (k%) progress towards the full compliance outcomes; (2) the gap is more severe when fair employers match global (vs local) statistics; (3) choices of local vs global statistics can paint dramatically different pictures of the performance vis-a-vis fairness desiderata of compliant versus non-compliant employers; (4) partial compliance based on local parity measures can induce extreme segregation. Finally, we discuss implications for auditors and insights concerning the design of regulatory frameworks. (shrink)

How do we go about weighing evidence, testing hypotheses, and making inferences? According to the model of _Inference to the Best Explanation_, we work out what to infer from the evidence by thinking about what would actually explain that evidence, and we take the ability of a hypothesis to explain the evidence as a sign that the hypothesis is correct. In _Inference to the Best Explanation_, Peter Lipton gives this important and influential idea the development and assessment it deserves. (...) The second edition has been substantially enlarged and reworked, with a new chapter on the relationship between explanation and Bayesianism, and an extension and defence of the account of contrastive explanation. It also includes an expanded defence of the claims that our inferences really are guided by diverse explanatory considerations, and that this pattern of inference can take us towards the truth. This edition of _Inference to the Best Explanation_ has also been updated throughout and includes a new bibliography. (shrink)

For decades, scholars in the social sciences and humanities have questioned the appropriateness and utility of prior review of their research by human subjects' ethics committees. This essay seeks to organize thematically some of their published complaints and to serve as a brief restatement of the major critiques of ethics review. In particular, it argues that 1) ethics committees impose silly restrictions, 2) ethics review is a solution in search of a problem, 3) ethics committees lack expertise, 4) ethics committees (...) apply inappropriate principles, 5) ethics review harms the innocent, and 6) better options exist.

Social studies of interdisciplinary science investigate how scientific collaborations approach complex challenges that require multiple disciplinary perspectives. In order for collaborators to meet these complex challenges, interdisciplinary collaborations must develop and maintain integrative capacity, understood as the ability to anticipate and weigh tradeoffs in the employment of different disciplinary approaches. Here we provide an account of how one group of interdisciplinary fog scientists intentionally catalyzed integrative capacity. Through conversation, collaborators negotiated their commitments regarding the ontology of fog systems and the (...) methodologies appropriate to studying fog systems, thereby enhancing capabilities which we take to constitute integrative capacity. On the ontological front, collaborators negotiated their commitments by setting boundaries to and within the system, layering different subsystems, focusing on key intersections of these subsystems, and agreeing on goals that would direct further investigation. On the methodological front, collaborators sequenced various methods, anchored methods at different scales, validated one method with another, standardized the outputs of related methods, and coordinated methods to fit a common model. By observing the process and form of collaborator conversations, this case study demonstrates that social studies of science can bring into critical focus how interdisciplinary collaborators work toward an integrated conceptualization of study systems.

Doxastic normativism is the thesis that norms are constitutive of or essential to belief, such that no mental state not subject to those norms counts as a belief. A common normativist view is that belief is essentially governed by a norm of truth. According to Krister Bykvist and Anandi Hattiangadi, truth norms for belief cannot be formulated without unpalatable consequences: they are either false or they impose unsatisfiable requirements on believers. I propose that we construe the fundamental norm of belief (...) as a knowledge norm, rather than a truth norm. I argue that a specific kind of knowledge norm—one that has a subject's obligation to believe that p depend on her being in a position to know that p—might avoid the well-known formulation problems with truth norms.

The current research investigates how prior preferences affect causal learning. Participants were tasked with repeatedly choosing policies (e.g., increase vs. decrease border security funding) in order to maximize the economic output of an imaginary country and inferred the influence of the policies on the economy. The task was challenging and ambiguous, allowing participants to interpret the relations between the policies and the economy in multiple ways. In three studies, we found evidence of motivated reasoning despite financial incentives for accuracy. For (...) example, participants who believed that border security funding should be increased were more likely to conclude that increasing border security funding actually caused a better economy in the task. In Study 2, we hypothesized that having neutral preferences (e.g., preferring neither increased nor decreased spending on border security) would lead to more accurate assessments overall, compared to having a strong initial preference; however, we did not find evidence for such an effect. In Study 3, we tested whether providing participants with possible functional forms of the policies (e.g., the policy takes some time to work or initially has a negative influence but eventually a positive influence) would lead to a smaller influence of motivated reasoning but found little evidence for this effect. This research advances the field of causal learning by studying the role of prior preferences, and in doing so, integrates the fields of causal learning and motivated reasoning using a novel explore‐exploit task.

Although mind-wandering occupies up to half of our waking thoughts, it is seldom discussed in philosophy. My paper brings these neglected thoughts into focus. I propose that mind-wandering is unguided attention. Guidance in my sense concerns how attention is monitored and regulated as it unfolds over time. Roughly speaking, someone’s attention is guided if she would feel pulled back, were she distracted from her current focus. Because our wandering thoughts drift unchecked from topic to topic, they are unguided. One motivation (...) for my theory is what I call the “Puzzle of the Purposeful Wanderer”. On the one hand, mind-wandering seems essentially purposeless; almost by definition, it contrasts with goal-directed cognition. On the other hand, empirical evidence suggests that our minds frequently wander to our goals. My solution to the puzzle is this: mind-wandering is purposeless in one way—it is unguided—but purposeful in another—it is frequently caused, and thus motivated, by our goals. Another motivation for my theory is to distinguish mind-wandering from two antithetical forms of cognition: absorption and rumination. Surprisingly, previous theories cannot capture these distinctions. I can: on my view, absorption and rumination are guided, whereas mind-wandering is not. My paper has four parts. Section 1 spells out the puzzle. Sections 2 and 3 explicate two extant views of mind-wandering—the first held by most cognitive scientists, the second by Thomas Metzinger. Section 4 uses the limitations of these theories to motivate my own: mind-wandering is unguided attention. (shrink)

According to one recently popular “flicker of freedom” style response to Frankfurt-style arguments against the Principle of Alternative Possibilities—the “Triple O” flicker strategy—agents in Frankfurt-style cases are really or most fundamentally morally responsible for performing an action (A-ing) on their own, but not for A-ing simpliciter. This essay has two related aims. First, I offer an interpretation of the Triple O strategy which insulates it against an objection raised by Carolina Sartorio in “Flickers of Freedom and Moral Luck.” Second, I (...) argue that a sub-version of the strategy (“the inheritance view”) according to which agents in Frankfurt-style cases are derivatively responsible for A-ing simpliciter in virtue of A-ing on their own, for which they are basically responsible, is untenable. I show that “A-ing simpliciter” is not plausibly an outcome of “A-ing on one’s own” in the sense required for the transfer of responsibility. Several candidates for the generative relation via which responsibility might be transferred are canvassed, and it is found that none of these relations plausibly hold between an agent’s A-ing on his own and his A-ing simpliciter. Next, I identify the generative relation (if any) that does hold between these items and show that the direction of generation problematically conflicts with the direction of the inheritance view’s purported transfer of responsibility.

In this paper I argue that Kant’s pre-critical ontology, though generally dismissed by environmental philosophers, provides ecological lessons by way of its metaphysical affinities with environmental philosophy. First, I reference where environmental philosophy tends to place Kant and highlight his relative marginalization. This marginalization makes sense given focus on his critical works. I then outline Kant’s pre-critical ontological framework and characterize the ways in which it is ecological. Finally, I conclude with some ecological reflections on the pre-critical philosophy and its (...) possible relevance for contemporary environmental issues. (shrink)

Individualist normative theories appear inadequate for the complex moral challenges of climate change. In climate ethics, this is especially notable with the relative marginalization of Kant. I argue that Kant’s philosophy, understood through its historical and cosmopolitan dimensions, has untapped potential for the climate crisis. First, I situate Kant in climate ethics and evaluate his marginalization due to perceived individualism, interiority and anthropocentrism. Then, I explore aspects of Kant’s historical and cosmopolitan writings, which present a global, future-orientated picture of humanity. (...) Ultimately, Kant’s philosophy offers a unique take on the climate deadlock capable of sustaining the individual in the collective. (shrink)

Causal models of agents have been used to analyse the safety aspects of machine learning systems. But identifying agents is non-trivial -- often the causal model is just assumed by the modeler without much justification -- and modelling failures can lead to mistakes in the safety analysis. This paper proposes the first formal causal definition of agents -- roughly that agents are systems that would adapt their policy if their actions influenced the world in a different way. From this we (...) derive the first causal discovery algorithm for discovering agents from empirical data, and give algorithms for translating between causal models and game-theoretic influence diagrams. We demonstrate our approach by resolving some previous confusions caused by incorrect causal modelling of agents. (shrink)

A large body of research has indicated international students in the United States and abroad experience difficulties understanding what academic integrity is and how to avoid academic misconduct, 159–172 2011; Brown & Howell, 2001; Gullifer and Tyson Studies in Higher Education, 39, 1202-1218 2014). While most studies focus on academic misconduct and academic corruption in research ethics, 339-358 2014), this study analyzes the length, English-language readability, and translation of academic integrity policies of 453 four-year U.S. institutions of higher education. Findings (...) indicate average academic integrity policies are over 2000 words long, are written above the 16th-grade reading level, and are very rarely translated into a language other than English. In addition, no institutions published their academic integrity policies in full on their institutional international student website, possibly rendering the policy difficult to locate on the institution’s website for international students. Implications for research, policy, and practice are addressed. (shrink)

This essay will address the question for what good or purpose is evil. First, an examination of the use-mention distinction between evil and “evil” produces two distinct questions: what good is the presence of evil in the world, and what good is the concept of evil as part of our ethical vocabulary describing human interaction. By severing all logically necessary connections between evil and greater goods, we discover that the answer to the first question—what good is evil in the world—is (...) none whatsoever. Evil deeds leave an enduring and destructive impact on people’s lives. Attempts to justify this ruination belittle the torment that sufferers of evil sustain. Because there is no normative vindication of evil’s existence, recognizing it as an indelible fact of human interaction proves to be crucial to understanding elemental features of the moral community and one’s role within it. Hence, the answer to the second question—what good is the concept of evil—is that it is of the utmost importance. Insofar as evil is a perpetual element of human interaction, being aware of this very fact—that is, understanding the concept of evil—is central to comprehending one’s moral agency, to appropriately reacting to others in the moral community, and to possibly inhibiting future incidents of evil.

In numerous studies, experimental economists have documented the fact that people tend to propose that divisible goods be divided equally. It has often been proposed, most notably by the sociobiologists, that this tendency may have a biological basis, and might be the product of evolution and natural selection. ;My dissertation addresses methodological and philosophical problems that arise in the course of establishing this naturalistic claim. Specifically, the focus of this dissertation is on the project of using evolutionary game theory to (...) model the emergence of behavioral norms in a population. ;Chapter 1 briefly surveys the experimental economics literature that supports the existence of such behavioral propensities, and gives an overview of the dissertation. Chapter 2 introduces the fundamental concepts of game theory and evolutionary game theory. Chapter 3 argues that certain robustness failures may be overcome if group selection mechanisms are incorporated into the evolutionary models. Chapter 5 defends Peter Railton's causal theory of explanation, and argues that it best accommodates the dynamical models of evolutionary game theory. Chapter 6 addresses the question of whether a descriptive account of the origins of our moral intuitions is relevant to the normative project of identifying our moral obligations, and critiques arguments by Peter Singer and Peter Unger that our moral intuitions lack justification.

When confronting the unexplained, it is helpful to consider it from many different points of view. In an essay published in 2004, entitled "Sensors, Filters, and the Source of Reality," Robert Jahn and Brenda Dunne of Princeton University's PEAR laboratory proposed that consciousness constructs its reality by ordering the information it derives from the external world through an array of physiological, psychological, and cultural filters. This thesis has now been considered by nineteen distinguished scholars who here present their commentaries from (...) a broad spectrum of professional and personal perspectives. Drawn from such diverse backgrounds as art, Buddhism, evolutionary biology, fantasy, out-of-body experiences, philosophy, physics, psychology, semiotics, and systems engineering, among others, these contributions offer an assortment of unique and fascinating glimpses of how our experiences and their styles of representation are reflected through these filters of consciousness.

Much work in the philosophy of religion has been devoted to exploring the virtue of faith. Very little of it, however, has done so from the perspective of Christian worship and liturgical practice. In this essay, I explore the virtue of faith, articulated in a traditionally Catholic manner, as it is practiced, engaged, and deepened through participation in the Eucharist. I begin by emphasizing both the cognitive and the volitional dimensions of a robust conception of the virtue of faith and (...) then show how devout Eucharistic practice confirms and strengthens them, affording believers a unique opportunity to deepen their belief and concretely strengthen their trust in God. I conclude by noting how a Eucharistic approach to faith can avoid a common criticism—that faith is exceedingly passive—and also help us to understand why faith and religious practice can so easily become stagnant.

Analytic philosophers have disputed the nature of “artistic value” for over six decades, bringing much needed clarity and rigor to a subject discussed with fashionable obscurity in other disciplines. This essay frames debates between analytic philosophers on artistic value and suggests new directions for future research. In particular, the problem of “intrinsic value” is considered, that is, whether a work’s value derives from its experienced properties, as a work of art, or from cultural trends outside the work’s properties. It is (...) argued that neurobiological research helps resolve perceived differences between a work’s intrinsic and extrinsic values. A work can be both rewarding and punishing on its own, “intrinsic” merit—as a percipient, real thing in the world evoking predictable kinds of emotion—and with respect to ever shifting, “extrinsic” cultural norms.

Dieser Beitrag untersucht die Entstehung und die Wirkung von Luther an unsere Zeit, Karl Gottlieb Bretschneiders vielgelesenes Buch der Auszüge, als Fallstudie darüber, wie moderne wissenschaftliche Theologen und Herausgeber Luther gelesen, kommentiert und anderen Lesern vorgestellt haben: in diesem Beispiel als Rationalist. Das Buch war umstritten. Der Beitrag befasst sich auch mit zwei konkurrierenden Auswahlen von Luthers Schriften, die von den konservativeren Protestanten Friedrich Perthes und Hans Lorenz Andreas Vent sowie den ultramontanen Katholiken Nikolaus Weis und Andreas Räß als Antwort (...) verfasst wurden. Es deutet darauf hin, dass eine stärkere Berücksichtigung solcher Zusammenstellungen und der Arbeitsmethoden der Compiler selbst – als Teil der kritischen Geschichte der Wissenschaft – sowohl unser Verständnis des tatsächlichen Einsatzes der Reformer und ihrer breiten Rezeption durch verschiedene Leser bereichern als auch neues Licht werfen wird über die Polemik des frühen neunzehnten Jahrhunderts. This article examines the creation and impact of Luther for Our Time, Karl Gottlieb Bretschneider’s much-read book of excerpts, as a case study of how modern scientific theologians and editors read, annotated, and introduced Luther to other readers: in this instance as a rationalist. The book was controversial. The article also looks at two competing selections of Luther’s texts prepared in response by the more conservative Protestants Friedrich Perthes and Hans Lorenz Andreas Vent and the ultramontane Catholics Nikolaus Weis and Andreas Räß. It suggests that greater consideration of such compilations and the working methods of the compilers themselves – part of the critical history of scholarship – will both enrich our understanding of the actual use of reformers and their broad reception by various readers, as well as shed new light on the polemics of the early nineteenth century.

Although scientists dating back to Darwin have noted the importance of the body in communicating emotion, current research on emotion communication tends to emphasize the face. In this article we review the evidence for bodily expressions of emotions—that is, the handful of emotions that are displayed and recognized from certain bodily behaviors (i.e., pride, joy, sadness, shame, embarrassment, anger, fear, and disgust). We also review the previously developed coding systems available for identifying emotions from bodily behaviors. Although no extant coding (...) system provides an exhaustive list of bodily behaviors known to communicate a panoply of emotions, our review provides the foundation for developing such a system.

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. I (...) argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.

A revisionist view incorrectly identifies a growing awareness of historical and cultural relativity by scholars of Roman law in sixteenth-century France with a modern historical consciousness. Friedrich Meinecke more correctly identified historicism as the juncture of the ideas of individuality and development. The perception by these Renaissance scholars of successive changes in language and law only constitutes an awareness of individuality, not of an idea of development. They conceived of an entity as unfolding from a germ or essence, an essential (...) quality which defined it as an individuality. They could not conceive of an entity as developing in relation to its circumstances. (shrink)

The thirteenth century mystic Ibn ʻArabi was the foremost Sufi theorist of the premodern era. For more than a century, Western scholars and esotericists have heralded his universalism, arguing that he saw all contemporaneous religions as equally valid. In Rethinking Ibn ʻArabi, Gregory Lipton calls this image into question and throws into relief how Ibn ʻArabi's discourse is inseparably intertwined with the absolutist vision of his own religious milieu-- that is, the triumphant claim that Islam fulfilled, superseded, and therefore (...) abrogated all previous revealed religions. Lipton juxtaposes Ibn ʻArabi's absolutist conception with the later reception of his ideas, exploring how they have been read, appropriated, and universalized within the reigning interpretive field of Perennial Philosophy in the study of Sufism. The contours that surface through this comparative analysis trace the discursive practices that inform Ibn ʻArabi's Western reception back to the eighteenth and nineteenth century study of 'authentic' religion, where European ethno-racial superiority was wielded against the Semitic Other - both Jewish and Muslim. Lipton argues that supersessionist models of exclusivism are buried under contemporary Western constructions of religious authenticity in ways that ironically mirror Ibn ʻArabi's medieval absolutism.

Efforts from diverse disciplines, including evolutionary studies and biomechanical experiments, have yielded new insights into the genetic, signaling, and mechanical control of tooth formation and functions. Evidence from fossils and non‐model organisms has revealed that a common set of genes underlie tooth‐forming potential of epithelia, and changes in signaling environments subsequently result in specialized dentitions, maintenance of dental stem cells, and other phenotypic adaptations. In addition to chemical signaling, tissue forces generated through epithelial contraction, differential growth, and skeletal constraints act (...) in parallel to shape the tooth throughout development. Here recent advances in understanding dental development from these studies are reviewed and important gaps that can be filled through continued application of evolutionary and biomechanical approaches are discussed.

Our paper serves as an introduction to a budding field: the philosophy of mind-wandering. We begin with a philosophical critique of the standard psychological definitions of mind-wandering as task-unrelated or stimulus-independent. Although these definitions have helped bring mind-wandering research onto centre stage in psychology and cognitive neuroscience, they have substantial limitations that researchers must overcome to move forward. Specifically, the standard definitions do not account for (i) the dynamics of mind wandering, (ii) task-unrelated thought that does not qualify as mind-wandering, (...) and (iii) the ways that mind-wandering can be task-related. We then survey three philosophical accounts that improve upon the current psychological definitions. We first present our account of mind-wandering as “unguided thinking”. Next we review Thomas Metzinger’s view that mind-wandering can be defined as thought lacking meta-awareness and cognitive agency, as well as Peter Carruthers’s and Fabian Dorsch’s definitions of mind-wandering as disunified thinking. We argue that these latter views are inadequate, and we show that our definition of mind-wandering as unguided thinking is not only conceptually and phenomenologically precise but also can be operationalized in a principled way for empirical research.

This paper reports on a study of crowd-sourcing ‘study aid’ web platforms. Students are sharing completed academic coursework through a growing network of ‘study aid’ web platforms like CourseHero.com. These websites facilitate the crowd-sourced exchange of coursework, and effectively support plagiarism. However, virtually no data exists concerning the scope or extent of coursework being shared through these platforms. This paper reports on two experiments to monitor the frequency of coursework from a sample university uploaded onto CourseHero.com. Ultimately, both experiments failed (...) to produce a clear or meaningful measurement of coursework upload frequency. The apparently widespread use of these crowd-sourcing ‘study aid’ websites and the failure of these experiments demonstrates the need for further investigation into how much coursework is being shared through such platforms, how frequently it is shared, and what kind of coursework is being shared. Addressing these issues is an important step into measuring the impact of these wellsprings of academically dishonest behavior. (shrink)

The contours of sustainable systems are defined according to communities’ goals and values. As researchers shift from sustainability-in-the-abstract to sustainability-as-a-concrete-research-challenge, democratic deliberation is essential for ensuring that communities determine what systems ought to be sustained. Discourse analysis of dialogue with Michigan direct marketing farmers suggests eight sustainability values – economic efficiency, community connectedness, stewardship, justice, ecologism, self-reliance, preservationism and health – which informed the practices of these farmers. Whereas common heuristics of sustainability suggest values can be pursued harmoniously, we discuss (...) how this typology reflects the more intricate project of balancing values in tension with one another.

Attribution theorists assume that character information informs judgments of blame. But there is disagreement over why. One camp holds that character information is a fundamental determinant of blame. Another camp holds that character information merely provides evidence about the mental states and processes that determine responsibility. We argue for a two-channel view, where character simultaneously has fundamental and evidential effects on blame. In two large factorial studies (n = 495), participants rate whether someone is blameworthy when he makes a mistake (...) (burns a cake or misses a bus stop). Although mental state inferences predict blame judgments, character information does not. Using mediation analyses, we find that character information influences responsibility via two channels (Studies 3–4; n = 447), which are sensitive to different kinds of information (Study 5; n = 149). On the one hand, forgetfulness increases judgments of responsibility, because mental lapses manifest an objectionable character flaw. On the other hand, forgetfulness decreases judgments of state control, which in turn decreases responsibility judgments. These two channels cancel out, which is why we find no aggregate effect of forgetfulness on responsibility. Our results challenge several fundamental assumptions about the role of character information in moral judgment, including that good character typically mitigates blame. (shrink)
