It is often assumed that engaging in a one‐on‐one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) (...) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5‐step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural‐language‐based computer tutoring (Why2‐Atlas and Why2‐AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text‐based control conditions.

SummaryChristians often presume that immediate and universally extensive divine governance of human behavior is incompatible with human agency and responsibility. Against this presumption, Kathryn Tanner argues for a distinctive metalinguistic paradigm whereby Christians can coherently speak of God’s transcendence in such a way that divine action could never in principle ‘compete’ with human action. Thus, it is said, God can comprehensively will each human action without thereby compromising significant human freedom and corresponding moral responsibility. In this article, it is (...) argued that Tanner’s non-competitivist paradigm fails to circumvent a theological version of the ‘direct argument’ for the incompatibility between human moral responsibility and causal determinism.

Recent work on Mary Shepherd has largely focused on her metaphysics, especially as a response to Berkeley and Hume. However, relatively little attention has thus far been paid to the epistemological aspects of Shepherd’s program. What little attention Shepherd’s epistemology has received has tended to cast her as providing an unsatisfactory response to the skeptical challenge issued by Hume. For example, Walter Ott and Jeremy Fantl have each suggested that Shepherd cannot avoid Hume’s inductive skepticism even if she is granted (...) her metaphysics. In this paper, I examine Shepherd’s epistemology and argue that her response to Hume is more successful than the current literature suggests. In particular, I argue that, if Shepherd is granted her metaphysics, she can answer Hume’s demand for a rational justification of ordinary inductive inferences via a deductively justified uniformity principle and an appeal to parsimony.

The ‘black box problem’ is a long-standing talking point in debates about artificial intelligence. This is a significant point of tension between ethicists, programmers, clinicians and anyone else working on developing AI for healthcare applications. However, the precise definition of these systems are often left undefined, vague, unclear or are assumed to be standardised within AI circles. This leads to situations where individuals working on AI talk over each other and has been invoked in numerous debates between opaque and explainable (...) systems. This paper proposes a coherent and clear definition for the black box problem to assist in future discussions about AI in healthcare. This is accomplished by synthesising various definitions in the literature and examining several criteria that can be extrapolated from these definitions. There are no data in this work. (shrink)

We often feel survivor guilt when the very circumstances that harm others leave us unscathed. Although survivor guilt is both commonplace and intelligible, it raises a puzzle for the standard philosophical account of guilt, according to which people feel guilt only when they take themselves to be morally blameworthy. The standard account implies that survivor guilt is uniformly unfitting, as people are not blameworthy simply for having fared better than others. In this paper, we offer a rival account of guilt, (...) the relational account of guilt, which makes sense of survivor guilt and other forms of guilt without self-blame while preserving the intelligibility of guilt about culpable wrongdoing. According to this account, guilt involves the feeling of being unable to justify ourselves to others, and we lack self-justification when we (however blamelessly) stand on the positive side of an undesirable asymmetry with them. When someone survives something that those around her do not, the disparity in outcome constitutes an asymmetry that is often undesirable, because it arises from luck or violates a requirement of solidarity. Thus, survivor guilt is often fitting. (shrink)

Michael Tanner's readable introduction to Nietzsche's life and work examines the numerous ambiguities inherent in his writings. It also explodes the many misconceptions fostered in the hundred years since Nietzsche wrote, prophetically: 'Do not, above all, confound me with what I amnot!'.

Are demands for equality motivated by envy? Nietzsche, Freud, Hayek, and Nozick all thought so. Call this the Envy Objection. For egalitarians, the Envy Objection is meant to sting. Many egalitarians have tried to evade the Envy Objection.. But should egalitarians be worried about envy? In this paper, I argue that egalitarians should stop worrying and learn to love envy. I argue that the persistent unwillingness to embrace the Envy Objection is rooted in a common misunderstanding of the nature of (...) the charge, what it reveals, and what can be said in response to it. I develop what Bernard Williams might call a vindicatory genealogy of envy, thereby allowing us to see that envy, rather than undermining egalitarian intuitions, can in fact play a distinct justificatory role (when it is fitting), which undermines the Envy Objection.

Strawson (1994) and Peacocke (1992) introduced thought experiments that show that it seems intuitive that there is, in some way, an experiential character to mental events of understanding. Some (e.g., Siewert 1998, 2011; Pitt 2004) try to explain these intuitions by saying that just as we have, say, headache experiences and visual experiences of blueness, so too we have experiences of understanding. Others (e.g., Prinz 2006, 2011; Tye 1996) propose that these intuitions can be explained without positing experiences of understanding. (...) Call this the debate between Realism and Anti-Realism about experiences of understanding. This paper aims to advance that debate in two ways. In the first half, I develop more precise characterizations of what Realists and Anti-Realists propose. In the second half, I distinguish the four most plausible versions of Anti-Realism and argue that Realism better explains the target intuition than any of them does. (shrink)

What does everyone in the modern world need to know? Renowned psychologist Jordan B. Peterson's answer to this most difficult of questions uniquely combines the hard-won truths of ancient tradition with the stunning revelations of cutting-edge scientific research. Humorous, surprising and informative, Dr. Peterson tells us why skateboarding boys and girls must be left alone, what terrible fate awaits those who criticize too easily, and why you should always pet a cat when you meet one on the street. What (...) does the nervous system of the lowly lobster have to tell us about standing up straight (with our shoulders back) and about success in life? Why did ancient Egyptians worship the capacity to pay careful attention as the highest of gods? What dreadful paths do people tread when they become resentful, arrogant and vengeful? Dr. Peterson journeys broadly, discussing discipline, freedom, adventure and responsibility, distilling the world's wisdom into 12 practical and profound rules for life. [This book] shatters the modern commonplaces of science, faith and human nature, while transforming and ennobling the mind and spirit of its readers. (shrink)

If we are going to treat other species so very differently from our own — killing, eating and experimenting on pigs and sheep, for example, but never human beings — then it seems we need to come up with some morally relevant difference between us and them that justifies this difference in treatment. Otherwise it appears we are guilty of bigotry (in just the same way that someone who discriminates on the basis of race or sex is guilty of bigotry). (...) But what is this morally relevant difference? Julia Tanner's article examines, and rejects, some of the most popular answers to this question. -/- . (shrink)

Chemical kinds are generally treated as having timelessly fixed identities. Biological kinds are generally treated as evolved and/or evolving entities. So what kind of kind is a biochemical kind?

The #MeToo movement generated a feminist insistence that we “believe women.” But the men accused of assault, harassment, and other violations frequently defended themselves with the insistence that they had always “respected women” – sometimes, going so far as to get numerous women to sign letters swearing that these men had always respected them. This common MeToo defense reveals the core inconsistency – and the core entitlement – at the heart of misogyny and sexual injustice: some women deserve respect. But (...) the duty to respect those women relies on an invisible entitlement to disrespect – indeed, to assault, harass, dominate, or exploit – others. This chapter explores consent’s role within the superstructure of misogyny and sexual injustice, arguing what consent is a key apparatus of white supremacy. It argues that consent has been constructed through dynamics of colonial and racist sexual entitlement, mapping some (white) women as deserving of respect and the right to consent, while marking other women as expendable or disposable within the sexual economy. This means not only that consent is historically constructed as white, but also that whiteness, and in particular, white womanhood, is constructed through consent. Thus, white women’s right to consent – or to refuse – is premised upon the inability of other women to do so. In this way, the right to sexual consent does not disrupt the norm of male sexual entitlement. Consent has always been premised on non-consent, from coloniality and slavery to contemporary porn, which offers a vision of the world without proper consent, so that granting consent to actual women is an exceptional practice, an “act of respect.” By including race and class alongside gender in my analysis of consent, I argue that contemporary feminist visions of sexual justice must do more than defend or ameliorate consent, but develop intersectional interrogations of sexual justice that reckon with the complicities of consent.

Personalized genomics companies (PG; also called ‘direct-to-consumer genetics’) are businesses marketing genetic testing to consumers over the Internet. While much has been written about these new businesses, little attention has been given to their roles in science communication. This paper provides an analysis of the gene concept presented to customers and the relation between the information given and the science behind PG. Two quite different gene concepts are present in company rhetoric, but only one features in the science. To explain (...) this, we must appreciate the delicate tension between PG, academic science, public expectation, and market forces. (shrink)

This paper attempts to demonstrate Max Scheler’s anticipation of and continued relevance to a burgeoning trend of essence-based accounts of modality, chief among them being Kit Fine’s landmark 1994 “Essence and Modality.” I argue that Scheler’s account of the material a priori not only anticipates the picture of essence-based modality suggested by Fine, but moreover offers resources with the potential to resolve key challenges for the Finean program. In particular, Fine’s account runs into problems in explaining how formal logical necessities (...) are to be grounded in essences, challenges that put pressure on the essentialist to adopt a non-propositional account of the nature of logical principles. I argue that one such account can be found in Scheler’s notion of the material a priori, according to which all necessary propositional truth is grounded in a realm of experientially given yet a priori "phenomenological facts." After showing the general rapprochement between Scheler’s and Fine’s accounts of regional modality, I then turn to address Scheler’s attempt to ground formal logical principles in essences. On Scheler’s picture, propositions expressing formal logical truths are true in virtue of the domain of essences in two senses: In terms of what Scheler calls objective necessity, they are true insofar as they coincide with the essential facts and interconnections shared by all possible regions of being; In terms of what he calls subjective necessity, they are true in virtue of these same essential facts and interconnections insofar as they have become “functionalized” into law-like patterns of cognition.

All else being equal, can granting the objective purport of moral experience support a presumption in favor of some form of moral objectivism? Don Loeb (2007) has argued that even if we grant that moral experience appears to present us with a realm of objective moral fact—something he denies we have reason to do in the first place—the objective purport of moral experience cannot by itself provide even prima facie support for moral objectivism. In this paper, I contend against Loeb (...) that granting the objective purport of ordinary moral experience is sufficient to support a defeasible presumption in favor of moral objectivism, and this by constituting non-explanatory, comparative confirmation that incrementally raises the prima facie likelihood that moral facts exist. More specifically, I appeal to a modest confirmation principle shared by Likelihoodists and Bayesieans - namely, the Weak Law of Likelihood - in an effort to show that (i) at a minimum, moral experience establishes a middling scrutable probability for a sufficient but not necessary condition of moral objectivism being true, and that (ii) this moderate probability in turn constitutes evidence that makes it prima facie more probable than not that some form of moral objectivism is true.

This Element examines Kant's innovative account of labour in his political philosophy and develops an intersectional analysis of Kant. By demonstrating that Kant's analysis of slavery, citizenship, and sex developed in inter-linked ways over several decades, culminating in his development of a 'trichotomy' of Right, the author shows that Kant's normative account of independence is configured through his theory of labour, and is continuous with his anthropological accounts of race and gender, providing a systemic justification for the dependency of women (...) and non-whites embedded in his philosophy of right. By examining Kant's arguments about slavery as intertwined with his account of domestic labour, the author argues that his ultimate rejection of slavery may owe more to his changing conceptualization of labour than to his theory of race, and that his final arguments against slavery rehearse strategies for embedding intersectional patterns of domestic dependence in his account of the rightful state.

Are workers dominated? A recent suite of neo-republican and relational egalitarian philosophers think they are. Suppose they are right; that is, suppose that some workers are governed by an unjust and arbitrary power existing in labour relations, which persists even in the presence of the actual ability to exit. My question is this: does that give us reason to impose restrictions on firms? According to the so-called Efficiency Objection there are relevant trade-offs that need to be considered between the efficiency (...) of firms and the freedom of workers, and upon considering these trade-offs, we should reject workplace democracy. In this paper, I present a dilemma for the Efficiency Objection. I argue that either the Efficiency Objection is justified on moral grounds or non-moral grounds; if the Efficiency Objection is justified on moral grounds, then it fails because efficiency cannot be valued for its own sake (it is only instrumentally good); if the Efficiency Objection is justified on non-moral grounds, then it fails because of the respect that we owe to persons as persons; therefore, the Efficiency Objection fails.

Rules are meant to apply equally to all within their jurisdiction. However, some rules are frequently broken without consequence for most. These rules are only occasionally enforced, often at the discretion of a third-party observer. We propose that these rules—whose violations are frequent, and enforcement is rare—constitute a unique subclass of explicitly codified rules, which we call ‘phantom rules’ (e.g., proscribing jaywalking). Their apparent punishability is ambiguous and particularly susceptible to third-party motives. Across six experiments, (N = 1440) we validated (...) the existence of phantom rules and found evidence for their motivated enforcement. First, people played a modified Dictator Game with a novel frequently broken and rarely enforced rule (i.e., a phantom rule). People enforced this rule more often when the “dictator” was selfish (vs. fair) even though the rule only proscribed fractional offers (not selfishness). Then we turned to third person judgments of the U.S. legal system. We found these violations are recognizable to participants as both illegal and commonplace (Experiment 2), differentiable from violations of prototypical laws (Experiments 3) and enforced in a motivated way (Experiments 4a and 4b). Phantom rule violations (but not prototypical legal violations) are seen as more justifiably punished when the rule violator has also violated a social norm (vs. rule violation alone)—unless the motivation to punish has been satiated (Experiment 5). Phantom rules are frequently broken, codified rules. Consequently, their apparent punishability is ambiguous, and their enforcement is particularly susceptible to third party motives. (shrink)

In this paper I argue that Pereboom’s empirical objection to agent causation fails to undermine the most plausible version of agent-causal libertarianism. This is significant because Pereboom concedes that such libertarianism is conceptually coherent and only falls to empirical considerations. To substantiate these claims I outline Pereboom’s taxonomy of agent-causal views, develop the strongest version of his empirical objections, and then show that this objection fails to undermine what I consider the most plausible view of agent-causal libertarianism, namely, reconciliatory integrationist (...) agent-causalism. I then strengthen my criticism of Pereboom by responding to three objections to my view. I show that these objections, though initially challenging, fail to undermine my argument. I therefore conclude that, to this extent, agent-causal views remain a viable option in the contemporary free will debate. (shrink)

Several recent criticisms of the somatic marker hypothesis (SMH) identify multiple ambiguities in the way it has been formulated by its chief proponents. Here we provide evidence that this hypothesis has also been interpreted in various different ways by the scientific community. Our diagnosis of this problem is that SMH lacks an adequate computational-level account of practical decision making. Such an account is necessary for drawing meaningful links between neurological- and psychological-level data. The paper concludes by providing a simple, five-step (...) model of practical decision making. Recasting SMH in terms of this model generates more precise and empirically tractable computational-level hypotheses about the various ways that somatic markers might influence practical decisions.

A set of qubit channels has a classical representation when it is isomorphic to the convex closure of a group of classical channels. From Crowder and Martin (Proceedings of Quantum Physics and Logic, Electronic Notes in Theoretical Computer Science, 2009), we know that up to isomorphism there are five such sets, each corresponding to either a subgroup of the alternating group on four letters, or a subgroup of the symmetric group on three letters. In this paper, we show that the (...) classical representation of a qubit channel also carries its information theoretic data—in particular, both the Holevo capacity and the scope of a unital qubit channel can be completely calculated from a systematically determined classical channel.

Roy Sorensen introduced the concept of an epistemic blindspot in the 1980s. A proposition is an epistemic blindspot for some individual at some time if and only if that proposition is consistent but unknowable by that individual at that time.

In the second half, I show how such blindspots can contribute to and impair different pursuits of self-understanding. (...) My arguments throughout this paper draw on Luc Bovens’s account of hope.

Philip Reed argues that laws that grant people access to euthanasia on the basis of terminal illness are discriminatory. In support of this claim, he offers an argument by analogy: it would be discriminatory to offer a person access to euthanasia because they are women or because they are disabled, as such restricted access would send the message ‘that life as a woman or as a disabled person is (very often) not worth living’.1 And so it must also be discriminatory (...) to offer people access to euthanasia because they are terminally ill. Arguments by analogies are only as good as the analogies on which they are built. Having a terminal illness, I’m going to suggest, is not relevantly similar enough to either being disabled or being a member of an oppressed social group to make Reed’s claim compelling. Let’s explore each branch of the analogy in turn. Why think that terminal illness is relevantly unlike disability, in a way that makes offering access to euthanasia in the latter case discriminatory, but not the former? For one thing, terminal illness is necessarily time-limited. When my father was dying, he found himself in constant …. (shrink)
