Addressing concerns about the treatment of psychopaths, Grant Gillett and Flora Huang (2013) argue that we ought to accept a relational or holistic view of psychopathy and APSD rather than the default biomedical-deficit model since the latter “obscures moral truths about the psychopath”. This change in approach to the psychopath will both mitigate at least some of their moral responsibility for the harms they cause, and force communities to incur special obligations, so they claim, because the harms endured by psychopaths (...) will be understood as part of the cause for the harms they are guilty of committing. However, as I will argue, even if we accept that a relational or holistic approach is better suited to understand psychopathy (which is itself contentious), it does not follow that their responsibility is mitigated in a way that causes communities to have special obligations to them as Gillett and Huang suggest. A diagnosis of APSD or psychopathy does not, prima facie, exculpate an agent or suggest a different way of treating them. My discussion will focus on the widely accepted excusing conditions one must meet for responsibility to me mitigated and conclude, contra Gillett and Huang, that psychopaths are no different from you or I with regards to having a causal history that leads to action. Outside forces play a role in all of our behavior. If the psychopath is owed anything because of the way they have come to understand the world then we all are owed that same debt. (shrink)

There are a variety of ways to accomplish a goal. But how we choose to accomplish a goal matters, morally speaking. The focus of my dissertation is on the ways in which the use of pharmacological enhancements should affect our moral evaluations. I’m concerned with this central question: how should our decision to enhance or not affect our evaluation of the act or person in question? I discuss a number of moral evaluations including deontic evaluations of human action, which concern (...) assessments of actions being right, wrong, or obligatory; agent evaluations, which include assessments of how we should treat people; these include assessments of moral responsibility and just punishment; and outcome evaluations which include whether or not the completion of a goal is an achievement or not and whether such an achievement is meaningful or hollow. These latter evaluations have received much less attention and one goal in this dissertation is to remedy that gap in the literature. After carefully examining many of the arguments against the use of pharmacological enhancements and casting doubt on them, I conclude that utilizing various pharmacological enhancements is not only permissible in many contexts but may be obligatory in far more cases than has been previously suggested.

There is a widely held view that the rules forbidding the use of performance enhancing drugs (PEDs) are justified on grounds that utilizing these drugs constitutes cheating . In this chapter we engage with this assumption. Relying on an interpretative approach borrowed from Ronald Dworkin, we offer a novel analysis of cheating, one that makes it out to be a matter of inhibiting the attainment of certain sorts of achievements. These achievements are the important goods at the centre of sport, (...) the telos of sport. We then argue that a given enhancement should be regarded as cheating only when it inhibits or prevents competitors from realizing these important goods. (shrink)

Compassion is widely regarded as an important moral emotion – a fitting response to various cases of suffering and misfortune. Yet contemporary theorists have rarely given it sustained attention. This volume aims to fill this gap by offering answers to a number of questions surrounding this emotion.

Determinism is, roughly, the thesis that facts about the past and the laws of nature entail all truths. A venerable, age-old dilemma concerning responsibility distils to this: if either determinism is true or it is not true, we lack "responsibility-grounding" control. Either determinism is true or it is not true. So, we lack responsibility-grounding control. Deprived of such control, no one is ever morally responsible for anything. A number of the freshly-minted essays in this collection address aspects of this dilemma. (...) Responding to the horn that determinism undermines the freedom that responsibility (or moral obligation) requires, the freedom to do otherwise, some papers in this collection debate the merits of Frankfurt-style examples that purport to show that one can be responsible despite lacking alternatives. Responding to the horn that indeterminism implies luck or randomness, other papers discuss the strengths or shortcomings of libertarian free will or control. Also included in this collection are essays on the freedom requirements of moral obligation, forgiveness and free will, a "desert-free" conception of free will, and vicarious legal and moral responsibility. This chapter points to the importance of the topics discussed in the volume and interesting arguments worth noting. (shrink)

I articulate the challenge disagreement poses for epistemic contextualism, and then discuss several possible replies on behalf of the contextualist.

In the global academic capitalist race, academics, institutions and countries’ symbolic power results from the accumulation of scientific capital. This paper relies on the perspectives of system actors located at the institutional, national and international levels to assess the perceived importance of eight systemic factors in contributing to the comparative advantage of social-democratic regimes, namely Denmark, Finland, Norway and Sweden. A deductive thematic analysis performed on 56 transcripts and a one-way repeated-measure ANOVA performed on 324 questionnaires confirmed the hypotheses regarding (...) the positive influence of academic traditions and internationalization. This study contributes to the development of a varieties of academic capitalism approach to apprehend how political-economies condition higher education systems’ comparative advantage. (shrink)

The W-defense is among the most prominent arguments for the principle of alternative possibilities (PAP). Here I offer some considerations in support of the W-defense and respond to what I see as the most forceful objections to it to date. My response to these objections invokes the well-known flicker of freedom response to Frankfurt cases. I argue that the W-defense and the flicker response are mutually reinforcing and together yield a compelling defense of PAP.

Epistemicists claim that vague predicates have precise but unknow- able cutoffs. I argue against against the standard, Williamsonian, answer, that appeals to metalinguistic safety: we can know that p even if our true belief that p is metalinguistically lucky. I then propose that epistemicists should be diagonalized epistemicists and show how this alternative formulation of the view avoids the chal- lenge. However, in an M. Night Shyamalan-style twist, I then argue we should not be diagonalized epistemicists either.

Recent work in cognitive science of religion (CSR) is beginning to converge on a very interesting thesis—that, given the ordinary features of human minds operating in typical human environments, we are naturally disposed to believe in the existence of gods, among other religious ideas (e.g., seeAtran [2002], Barrett [2004; 2012], Bering [2011], Boyer [2001], Guthrie [1993], McCauley [2011], Pyysiäinen [2004; 2009]). In this paper, we explore whether such a discovery ultimately helps or hurts the atheist position—whether, for example, it lends (...) credence to atheism by explaining away religious belief or whether it actually strengthens some already powerful arguments against atheism in the relevant philosophical literature.We argue that the recent discoveries of CSR hurt, not help, the atheist position—that CSR, if anything, should not give atheists epistemic assurance.

Criticism plays an essential role in the growth of scientific knowledge. In some cases, however, criticism can have detrimental effects; for example, it can be used to ‘manufacture doubt’ for the purpose of impeding public policy making on issues such as tobacco consumption and greenhouse gas emissions (e.g., Oreskes & Conway 2010). In this paper, we build on previous work by Biddle and Leuschner (2015) who argue that criticism that meets certain conditions can be epistemically detrimental. We extend and refine (...) their account by arguing that such criticism can be epistemically corrupting—it can create social conditions that are conducive to the development of epistemic vice by agents operating within them.

Reformed epistemology and cognitive science have remarkably converged on belief in God. Reformed epistemology holds that belief in God is basic—that is, belief in God is a natural, non-inferential belief that is immediately produced by a cognitive faculty. Cognitive science of religion also holds that belief in gods is (often) non-reflectively and instinctively produced—that is, non-inferentially and automatically produced by a cognitive faculty or system. But there are differences. In this paper, we will show some remarkable points of convergence, and (...) a few points of divergence, between Reformed epistemology and the cognitive science of religion. (shrink)

Experimental philosophy (or “x-phi”) is a way of doing philosophy. It is “traditional” philosophy, but with a little something extra: In addition to the expected philosophical arguments and engagement, x-phi involves the use of empirical methods to test the empirical claims that arise. This extra bit strikes some as a new, perhaps radical, addition to philosophical practice. We don’t think so. As this chapter will show, empirical claims have been common across the history of Western philosophy, as have appeals to (...) empirical observation in attempting to support or subvert these claims. While conceptions of philosophy have changed over time, across these changes we find philosophers employing empirical methods in pursuing their philosophical questions. Our primary aim in this chapter is to illustrate this fact. We begin by discussing the relevance of history to experimental philosophy (Section 2), then offer a necessarily condensed and highly selective history of empirical work in Western philosophy, ranging from the ancients (Section 3), to the early moderns (Section 4), to the late moderns (Section 5), and on to the present (Section 6).

In his précis of a recent book, Richard Joyce writes, “My contention…is that…any epistemological benefit-of-the-doubt that might have been extended to moral beliefs…will be neutralized by the availability of an empirically confirmed moral genealogy that nowhere…presupposes their truth.” Such reasoning – falling under the heading “Genealogical Debunking Arguments” – is now commonplace. But how might “the availability of an empirically confirmed moral genealogy that nowhere… presupposes” the truth of our moral beliefs “neutralize” whatever “epistemological benefit-of-the-doubt that might have been extended (...) to” them? In this article, I argue that there appears to be no satisfactory answer to this question. The problem is quite general, applying to all arguments with the structure of Genealogical Debunking Arguments aimed at realism about a domain meeting two conditions. The Benacerraf-Field Challenge for mathematical realism affords an important special case. (shrink)

Recent scholarship in philosophy of science and technology has shown that scientific and technological decision making are laden with values, including values of a social, political, and/or ethical character. This paper examines the role of value judgments in the design of machine-learning systems generally and in recidivism-prediction algorithms specifically. Drawing on work on inductive and epistemic risk, the paper argues that ML systems are value laden in ways similar to human decision making, because the development and design of ML systems (...) requires human decisions that involve tradeoffs that reflect values. In many cases, these decisions have significant—and, in some cases, disparate—downstream impacts on human lives. After examining an influential court decision regarding the use of proprietary recidivism-prediction algorithms in criminal sentencing, Wisconsin v. Loomis, the paper provides three recommendations for the use of ML in penal systems. (shrink)

I develop a reduction of grounding to essence. My approach is to think about the relation between grounding and essence on the model of a certain conceptof existential dependence. I extend this concept of existential dependence in a coupleof ways and argue that these extensions provide a reduction of grounding to essenceif we use sorted variables that range over facts and take it that for a fact to obtain is forit to exist. I then use the account to resolve various (...) issues surrounding the concept of grounding and its connection with essence; apply the account to paradigm cases andto the impure logic of grounding; and respond to objections.

This paper focuses on the concept of collective essence: that some truths are essential to many items taken together. For example, that it is essential to conjunction and negation that they are truth-functionally complete. The concept of collective essence is one of the main innovations of recent work on the theory of essence. In a sense, this innovation is natural, since we make all sorts of plural predications. It stands to reason that there should be a distinction between essential and (...) accidental plural predications if there is a distinction among singular predications. In this paper I defend the view that the concept of collective essence is governed by the principle of Monotonicity: that something is essential to some items only if it is essential to any items to which they belong.

This work draws an analogical defence of strong emotionism—the metaethical claim that moral properties and concepts consist in the propensity of actions to elicit emotional responses from divergent emotional perspectives. I offer a theory that is in line with that of Prinz. I build an analogy between moral properties and what I call emotion-dispositional properties. These properties are picked out by predicates such as ‘annoying’, ‘frightening’ or ‘deplorable’ and appear to be uncontroversial and frequent cases of attribution error—the attributing of (...) subjective emotional states as mind-independent properties. I present a linguistic analysis supporting the claim that moral properties and their related concepts are reducible to a subset of emotion-dispositional properties and concepts. This is grounded in the observation that utterances featuring moral predicates function linguistically and conceptually in analogous ways to emotion-dispositional predicates. It follows from this view that asserted moral utterances are truth-apt relative to ethical communities, but that speakers misconceive the extensions of predicates. I show how the framework of Cognitive Linguistics allows us to explain this error. Further analysis of moral and non-moral utterances exposes the deeper conceptual schemas structuring language through cognitive construal processes. An understanding of these processes, coupled with an emotionist elucidation of moral properties and concepts, makes the attribution error an expected upshot of the emotionist thesis, rather than an uncomfortable consequence.

The aim of this paper is to address the neglected but important problem of differentiating between epistemically beneficial and epistemically detrimental dissent. By “dissent,” we refer to the act of objecting to a particular conclusion, especially one that is widely held. While dissent in science can clearly be beneficial, there might be some instances of dissent that not only fail to contribute to scientific progress, but actually impede it. Potential examples of this include the tobacco industry’s funding of studies that (...) questioned the link between smoking and lung cancer, and the attempt by the petroleum industry and other groups to cast doubt upon the conclusion that human consumption of fossil fuels contributes to global climate change. The problem of distinguishing between good and bad dissent is important because of the growing tendency of some stakeholders to attempt to delay political action by ’manufacturing doubt’. Our discussion in this paper focuses on climate science. This field, in our view, is rife with instances of bad dissent. On the basis of our discussion of climate science, we articulate a set of sufficient conditions for epistemically problematic dissent in general, which we call “the inductive risk account of epistemically detrimental dissent.”.

This paper examines the state of the field of “science and values”—particularly regarding the implications of the thesis of transient underdetermination for the ideal of value-free science, or what I call the “ideal of epistemic purity.” I do this by discussing some of the main arguments in the literature, both for and against the ideal. I examine a preliminary argument from transient underdetermination against the ideal of epistemic purity, and I discuss two different formulations of an objection to this argument—an (...) objection that requires the strict separation of the epistemic from the practical. A secondary aim of the paper is to suggest some future directions for the field, one of which is to replace the vocabulary of values that is often employed in the literature with a more precise one.

This essay* takes two notions of autonomy and two notions of explanation and argues that colours occur in explanations that fall under all of them. The claim that colours can be used to explain anything at all may seem to some people an outrage. But their pessimism is unjustified and the orthodox dispositional view which may seem to support it, I shall argue, itself has difficulties. In broad terms, Section 2 shows that there exist good straight scientific laws of colour, (...) constituting what one might call a phenomenal science. Section 3 offers a larger view of what we are doing when we attribute colours to things, a view which makes it a case of holistic explanation, similar in many ways to psychological explanation. Section 2 emphasizes the model of scientific explanation, and Section 3 the holistic model found in rational explanation; but it will emerge that colour explanation in different ways fits both models, as it also does the two principal notions of autonomy that the first section identifies.

Through the lenses of cognitive science of religion, successful god concepts must possess a number of features. God concepts must be counterintuitive, an intentional agent, possessing strategic information, able to act in the human world in detectable ways and capable of motivating behaviors that reinforce belief. That Santa Claus appears to be only inconsistently represented as having all five requisite features Santa has failed to develop a community of true believers and cult. Nevertheless, Santa concepts approximate a successful god concept (...) more closely than other widespread cultural characters such as Mickey Mouse and the Tooth Fairy, in part explaining Santa's relative cultural prominence.

What is it for something to be essential to an item? For some time, it was standard to think that the concept of necessity alone can provide an answer: for something to be essential to an item is for it to be strictly implied by the existence of that item. We now tend to think that this view fails because its analysans is insufficient for its analysandum. In response, some argue that we can supplement the analysis in terms of necessity (...) with a further condition. In this paper I argue that this view is untenable in its current form. I then provide a glimmer of hope to those who think that essence is at least partially analyzable in terms of necessity. (shrink)

The biological functions debate is a perennial topic in the philosophy of science. In the first full-length account of the nature and importance of biological functions for many years, Justin Garson presents an innovative new theory, the 'generalized selected effects theory of function', which seamlessly integrates evolutionary and developmental perspectives on biological functions. He develops the implications of the theory for contemporary debates in the philosophy of mind, the philosophy of medicine and psychiatry, the philosophy of biology, and biology (...) itself, addressing issues ranging from the nature of mental representation to our understanding of the function of the human genome. Clear, jargon-free, and engagingly written, with accessible examples and explanatory diagrams to illustrate the discussion, his book will be highly valuable for readers across philosophical and scientific disciplines.

ABSTRACTIn this paper, I develop a truthmaker semantics for essence and use the semantics to investigate the explanatory role of essence.

This book is a critical survey of and guidebook to the literature on biological functions. It ties in with current debates and developments, and at the same time, it looks back on the state of discourse in naturalized teleology prior to the 1970s. It also presents three significant new proposals. First, it describes the generalized selected effects theory, which is one version of the selected effects theory, maintaining that the function of a trait consists in the activity that led to (...) its differential persistence or reproduction in a population, and not merely its differential reproduction. Secondly, it advances “within-discipline pluralism” (as opposed to between-discipline pluralism) a new form of function pluralism, which emphasizes the coexistence of function concepts within diverse biological sub-disciplines. Lastly, it provides a critical assessment of recent alternatives to the selected effects theory of function, namely, the weak etiological theory and the systems-theoretic theory. The book argues that, to the extent that functions purport to offer causal explanations for the existence of a trait, there are no viable alternatives to the selected effects view. -/- The debate about biological functions is still as relevant and important to biology and philosophy as it ever was. Recent controversies surrounding the ENCODE Project Consortium in genetics, the nature of psychiatric classification, and the value of ecological restoration, all point to the continuing relevance to biology of philosophical discussion about the nature of functions. In philosophy, ongoing debates about the nature of biological information, intentionality, health and disease, mechanism, and even biological trait classification, are closely related to debates about biological functions.

The present study sought to determine whether Barrett's counterintuitiveness coding and quantifying scheme could be applied to cultural materials with sufficient intercoder reliability, provide evidence concerning just how counterintuitive is too counterintuitive for a concept to be a recurrent cultural idea, and test whether counterintuitive intentional agent concepts are more common in folktales than other classes of counterintuitive concepts. Seventy-three folktales from around the world were sampled from larger collections. Using Barrett's CI-Scheme, two independent coders identified 116 counterintuitive objects and (...) scored them for degree of counterintuitiveness with very high inter-rater concordance. Of folktales, 79% had one or two counterintuitive objects. Of the counterintuitive objects 93% had a counterintuitiveness score of only one. Of counterintuitive objects, 98% were agents. Results suggest the CI-Scheme may have utility for analyzing cultural materials, that the cognitive optimum for cultural transmission falls around one counterintuitive feature, and that counterintuitive agents are more common than other types of counterintuitive objects in folktales.

. Recent philosophers of science have not only revived the classical argument from inductive risk but extended it. I argue that some of the purported extensions do not fit cleanly within the schema of the original argument, and I discuss the problem of overdiagnosis of disease due to expanded disease definitions in order to show that there are some risks in the research process that are important and that very clearly fall outside of the domain of inductive risk. Finally, I (...) introduce the notion of epistemic risk in order to characterize such risks. (shrink)

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups in (...) academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against certain theories (...) in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

We identify a novel ‘cultural red king effect’ that, in many cases, results in stable arrangements which are to the detriment of minority groups. In particular, we show inequalities disadvantaging minority groups can naturally arise under an adaptive process when minority and majority members must routinely determine how to divide resources amongst themselves. We contend that these results show how inequalities disadvantaging minorities can likely arise by dint of their relative size and need not be a result of either explicit (...) nor implicit prejudices, nor due to intrinsic differences between minority and majority members.

Since the early 1980s, private, for-profit corporations have become increasingly involved in all aspects of scientific research, especially of biomedical research. In this essay, I argue that there are dangerous epistemic consequences of this trend, which should be more thoroughly examined by social epistemologists. In support of this claim, I discuss a recent episode of pharmaceutical research involving the painkiller Vioxx. I argue that the research on Vioxx was epistemically problematic and that the primary cause of these inadequacies was faulty (...) institutional arrangements. More specifically, the research was organized in such a way as to allow short-term commercial interests to compromise epistemic integrity. Thus, the Vioxx case study, in conjunction with numerous case studies developed elsewhere, provides strong reasons for believing that the privatization of the biomedical sciences is epistemically worrisome, and it suggests that the primary response to this situation should be a social, or organizational, one. What kind of organizational response would be most beneficial? I briefly discuss two prominent social epistemological proposals for how scientific research should be organized - namely those of Philip Kitcher and Helen Longino - and I suggest that they are incapable of dealing with the phenomenon of privatization. I then draw upon the Vioxx episode in order to outline an alternative suggestion for reorganizing certain aspects of pharmaceutical research. (shrink)

For epistemic subjects like us, updating our credences incurs epistemic costs. Expending our limited processing power and working memory to properly update our credences by some information can come at the cost of not responding to other available information. It is thus desirable to flesh out and compare alternative ways of taking information into account in light of cognitive shortcomings like our own. This paper is a preliminary attempt to do so. I argue that it is better, in a range (...) of circumstances and from the point of view of expected credal accuracy, for epistemic subjects like us not to update on available information that bears on propositions for which substantial evidence has been gathered than it is to update on information as it presents itself. In order to clarify the argument, and enable comparisons between information-response policies more generally, I develop a queue-theoretic model of learning for subjects with cognitive limitations. The model characterizes how policies for responding to information interact with a subject’s limitations to yield confidences. Finally, I discuss implications of the discussion for work on confidence, outright belief, and the relationship between those two states. The comparison of information-response policies helps to explain how some of the “biases” revealed by psychological research might be cognitively valuable, clarify views that take outright belief to be a kind of epistemic plan that resists reconsideration, and assuage certain “demandingness” worries for the hypothesis that we are credal reasoners.

Christian Protestants typically affirm both the essential moral perfection of heaven and the sufficiency of saving faith. Yet these two commitments generatean apparently self-destructive dilemma—one I call the dilemma of sanctification. The prima facie puzzle can be resolved in at least three ways. In this paper, I articulate the dilemma of sanctification in some detail and offer an argument against a widely-held Protestant solution I call provisionism. This constitutes indirect support for the solution I find most promising, namely, a doctrine (...) of purgatory. I close by sketching a model of purgatory consistent with Protestant soteriology.

Despite its small stature, "if" occupies a central place both in everyday language and the philosophical lexicon. In allowing us to talk about hypothetical situations, "if" raises a host of thorny philosophical puzzles about language and logic. Addressing them requires tools from linguistics, logic, probability theory, and metaphysics. Justin Khoo uses these tools to navigate a maze of interconnected issues about conditionals, some of which include: the nature of linguistic communication, the relationship between logical and natural languages, and the (...) relationship between different kinds of modality. According to Khoo's theory, conditionals form a unified class of expressions which share a common semantic core that encodes inferential dispositions. Thus, rather than represent the world, conditionals are devices used to communicate how we are disposed to infer. Khoo shows that this theory can be extended to predict the probabilities of conditionals, as well as how different kinds of conditionals differ both semantically and pragmatically. Khoo's book will make for a significant contribution to the literature on conditionals and should be of interest to philosophers, linguists, and computer scientists. (shrink)

Scholars have suggested that leaders’ ethical failures at the beginning of the twenty-first century have raised awareness about the importance of ethical leadership (EL). Yet, there has been no systematic effort to evaluate whether this awareness indeed led to changes in EL or how followers react to this leadership style over time. To address this gap, we examine the evolution in EL means, variability, and its associations with follower outcomes between 2004 and 2019. Our cross-temporal meta-analysis included 359 independent samples (...) from 314 studies published between 2005 and 2020 and focused on followers’ ratings of their leaders using the Ethical Leadership Scale (ELS; Brown et al., in Organizational Behavior and Human Decision Processes, 97(2), 117–134, 2005). Using cubic spline meta-regressions, our results indicated no global changes in EL mean levels and variability across the 15-year period. Nevertheless, country-level comparisons revealed different EL-trends in China (i.e. decrease) versus the United States (i.e. stable), and further moderation analyses highlighted the role of cultural value dimensions and national corruption rates. Finally, we also found that the relationship between EL and desirable follower outcomes (e.g. organizational citizenship behavior) became gradually stronger over time on a global level. These results provide a solid empirical basis to evaluate cross-temporal trends in EL and its (changing) impact on follower outcomes across the globe. (shrink)

Is modus ponens valid for the indicative conditional? McGee [1985] famously presents several alleged counterexamples to this inference rule. More recently, Kolodny and MacFarlane [2010] and Willer [2010] argue that modus ponens is unreliable in certain hypothetical contexts. However, none of these attacks undermines an informational conception of logic on which modus ponens is valid.
