Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

There is a tension between the reasonable desire not to be judgmental of other people’s behaviour or character, and the moral necessity of making negative judgments in some cases. I sketch a way in which we might accommodate both, via an evaluation of the good of reputation and the ethics of judgment of other people’s character and behaviour. I argue that a good reputation is a highly valuable good for its bearer, akin to a property right, and not to be (...) damaged without serious reason deriving from the demands of justice and the common welfare. Rash judgment wrongfully damages reputation and is sometimes a seriously immoral act. Rashness is not merely about lack of evidence, but involves lack of charity and is to be avoided even in some cases where the evidence of bad character or action is epistemically sufficient for judgment. I argue that the desirability of a good name for its holder, whether the reputation is deserved or not, means that in all but a relatively narrow range of cases it is always wrong to think badly of someone, even if they are bad.

This is a brief introduction to the origin and development of Protestant ethical works in the tradition of Aristotle’s Nicomachean Ethics.

Richard Baxter, one of the most famous Puritans of the seventeenth century, is generally known as a writer of practical and devotional literature. But he also excelled in knowledge of medieval and early modern scholastic theology, and was conversant with a wide variety of seventeenth-century philosophies. Baxter was among the early English polemicists to write against the mechanical philosophy of René Descartes and Pierre Gassendi in the years immediately following the establishment of the Royal Society. At the same time, he (...) was friends with Robert Boyle and Matthew Hale, corresponded with Joseph Glanvill, and engaged in philosophical controversy with Henry More. In this book, David Sytsma presents a chronological and thematic account of Baxter's relation to the people and concepts involved in the rise of mechanical philosophy in late-seventeenth-century England. -/- Drawing on largely unexamined works, including Baxter's Methodus Theologiae Christianae (1681) and manuscript treatises and correspondence, Sytsma discusses Baxter's response to mechanical philosophers on the nature of substance, laws of motion, the soul, and ethics. Analysis of these topics is framed by a consideration of the growth of Christian Epicureanism in England, Baxter's overall approach to reason and philosophy, and his attempt to understand creation as an analogical reflection of God's power, wisdom, and goodness, understood as vestigia Trinitatis. Baxter's views on reason, analogical knowledge of God, and vestigia Trinitatis draw on medieval precedents and directly inform a largely hostile, though partially accommodating, response to mechanical philosophy.

This essay examines the development of Reformed treatments of the affections in the period of early orthodoxy (ca. 1565-1640). I argue that discussion of the affections during this period grew within the broad framework of the Aristotelian psychology and certain polemical concerns initially established by early Reformed theologians. With the advent of Protestant universities and academies, Reformed ethicists and theologians treated the affections in greater detail, with a majority drawing on a generally Thomistic approach to the nature and division of (...) the affections, although not without a dissenting Scotistic minority.

To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal identity. First I argue that overemphasis (...) of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay. I would also like to thank Ellen Paul, whose suggestions have helped greatly to improve the essay's style and content. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

This critical edition is the first ever publication of Hale's Of the Law of Nature, which previously existed only in manuscript form. After discussing and defining the law in general, Hale examines the natural law in particular, its discovery and divine origin, and how it relates to both biblical and human laws. Hale's treatise, which was likely written as part of his personal meditations, and was circulated among English lawyers after his death, reveals not only the close relationship between law (...) and theology in his thought, but also the importance of natural law to early modern legal thought.

Corruptionism is the view that following physical death, the human being ceases to exist but their soul persists in the afterlife. Survivalism holds that both the human being and their soul persist in the afterlife, as distinct entities, with the soul constituting the human. Each position has its defenders, most of whom appeal both to metaphysical considerations and to the authority of St Thomas Aquinas. Corruptionists claim that survivalism violates a basic principle of any plausible mereology, while survivalists tend to (...) reject the principle, though without as much detail as one would like. In this paper I examine both the key exegetical issues and the mereological question, arguing that Aquinas cannot be shown to have supported the principle in question, and that the principle should be rejected on independent grounds. If correct, some key planks in support of survivalism are established, with others to await further examination. (shrink)

Many scholars have argued that the Protestant Reformation generally departed from virtue ethics, and this claim is often accepted by Protestant ethicists. This essay argues against such discontinuity by demonstrating John Calvin’s reception of ethical concepts from Augustine and Aristotle. Calvin drew on Augustine’s concept of eudaimonia and many aspects of Aristotle’s Nicomachean Ethics , including concepts of choice, habit, virtue as a mean, and the specific virtues of justice and prudence. Calvin also evaluated the problem of pagan virtue in (...) light of traditional Augustinian texts discussed in the medieval period. He interpreted the Decalogue as teaching virtue, including the cardinal virtues of justice and temperance. Calvin was not the harbinger of an entirely new ethical paradigm, but rather a participant in the mainstream of Christian thinkers who maintained a dual interest in Aristotelian and Augustinian eudaimonist virtue ethics.

This study aimed to understand the preserved elements of self-identity in persons with moderate to severe dementia attributable to Alzheimer’s disease. A semi-structured interview was developed to explore the narrative self among residents with dementia in a residential care facility and residents without dementia in an independent living setting. The interviews were transcribed verbatim from audio recordings and analyzed for common themes, while being sensitive to possible differences between the groups. The participants with dementia showed evidence of self-reference even though (...) losses in explicit memory were evident. The most noticeable difference between the two groups was time frame reference. Nonetheless, all participants showed understanding of their role in relationships and exhibited concrete preferences. Our findings suggest that memory loss and other cognitive deficits associated with moderate to severe dementia do not necessarily lead to a loss of “self.”. (shrink)

Context — Children and adults with psychopathic traits and conduct or oppositional defiant disorder demonstrate poor decision making and are impaired in reversal learning. However, the neural basis of this impairment has not previously been investigated. Furthermore, despite high comorbidity of psychopathic traits and attention deficit/hyperactivity disorder, to our knowledge, no research has attempted to distinguish neural correlates of childhood psychopathic traits and attention-deficit/hyperactivity disorder. Objective—To determine the neural regions that underlie the reversal learning impairments in children with psychopathic traits (...) plus conduct or oppositional defiant disorder. Design — Case-control study. Setting — Government clinical research institute. Participants — Forty-two adolescents aged 10 to 17 years: 14 with psychopathic traits and oppositional defiant disorder or conduct disorder, 14 with attention-deficit/hyperactivity disorder only, and 14 healthy controls. Main Outcome Measure — Blood oxygenation level–dependent signal as measured via functional magnetic resonance imaging during a probabilistic reversal task. Results — Children with psychopathic traits showed abnormal responses within the ventromedial prefrontal cortex (Brodmann area 10) during punished reversal errors compared with children wit hattention deficit/hyperactivity disorder and healthy children (P < .05 corrected for multiple comparisons). Conclusions — To our knowledge, this study provides the first evidence of abnormal ventromedial prefrontal cortex responsiveness in children with psychopathic traits and demonstrates this dysfunction was not attributable to comorbid attention-deficit/hyperactivity disorder. These findings suggest that reversal learning impairments in patients with developmental psychopathic traits relate to abnormal processing of reinforcement information. (shrink)

Significant associations have been found between specific human leukocyte antigen (HLA) alleles and organ transplant rejection, autoimmune disease development, and the response to infection. Traditional searches for disease associations have conventionally measured risk associated with the presence of individual HLA alleles. However, given the high level of HLA polymorphism, the pattern of amino acid variability, and the fact that most of the HLA variation occurs at functionally important sites, it may be that a combination of variable amino acid sites shared (...) by several alleles (shared epitopes) are better descriptors of the actual causative genetic variants. Here we describe a novel approach to genetic association analysis in which genes/proteins are broken down into smaller sequence features and then variant types defined for each feature, allowing for independent analysis of disease association with each sequence feature variant type. We have used this approach to analyze a cohort of systemic sclerosis patients and show that a sequence feature composed of specific amino acid residues in peptide binding pockets 4 and 7 of HLA-DRB1 explains much of the molecular determinant of risk for systemic sclerosis.

Beyond Dordt and ‘De Auxiliis’ explores post-Reformation inter-confessional theological exchange on soteriological topics including predestination, grace, and free choice. These doctrines remained controversial within confessional traditions after the Reformation, as Dominicans and Jesuits and later Calvinists and Arminians argued about these critical issues in the Augustinian theological heritage. Some of those involved in condemning Arminianism at the Synod of Dordt (1618-1619) were inspired by Dominican followers of Thomas Aquinas in Spain who had recently opposed the vigorous defense of free choice (...) by Jesuit Molinists in the Congregatio de auxiliis (1598-1607). This volume, appearing on the 400th anniversary of the closing of the Synod of Dordt, brings together a group of scholars working in fields that only rarely speak to one another to address these theological debates that cross geographical and confessional boundaries.

Behavioral genetic (BG) research has yielded many important discoveries about the origins of human behavior, but offers little insight into how we might improve outcomes. We posit that this gap in our knowledge base stems in part from the epidemiologic nature of BG research questions. Namely, BG studies focus on understanding etiology as it currently exists, rather than etiology in environments that could exist but do not as of yet (e.g., etiology following an intervention). Put another way, they focus exclusively (...) on the etiology of “what is” rather than “what could be”. The current paper discusses various aspects of this field-wide methodological reality, and offers a way to overcome it by demonstrating how behavioral geneticists can incorporate an experimental approach into their work. We outline an ongoing study that embeds a randomized intervention within a twin design, connecting “what is” and “what could be” for the first time. We then lay out a more general framework for a new field—experimental BGs—which has the potential to advance both scientific inquiry and related philosophical discussions. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

The computational genomics community has come increasingly to rely on the methodology of creating annotations of scientific literature using terms from controlled structured vocabularies such as the Gene Ontology (GO). We here address the question of what such annotations signify and of how they are created by working biologists. Our goal is to promote a better understanding of how the results of experiments are captured in annotations in the hope that this will lead to better representations of biological reality through (...) both the annotation process and ontology development, and in more informed use of the GO resources by experimental scientists.

Recent research on the metaethical beliefs of ordinary people appears to show that they are metaethical pluralists that adopt different metaethical standards for different moral judgments. Yet the methods used to evaluate folk metaethical belief rely on the assumption that participants interpret what they are asked in metaethical terms. We argue that most participants do not interpret questions designed to elicit metaethical beliefs in metaethical terms, or at least not in the way researchers intend. As a result, existing methods are (...) not reliable measures of metaethical belief. We end by discussing the implications of our account for the philosophical and practical implications of research on the psychology of metaethics. (shrink)

In this thesis I offer an interpretation of Arthur Schopenhauer’s pessimism. I argue against interpreting Schopenhauer’s pessimism as if it were merely a matter of temperament, and I resist the urge to find a single standard argument for pessimism in Schopenhauer’s work. Instead, I treat Schopenhauer’s pessimism as inherently variegated, composed of several distinct but interrelated pessimistic positions, each of which is supported by its own argument. I begin by examining Schopenhauer’s famous argument that willing necessitates suffering, which I defend (...) against the misrepresentative interpretation advocated by Ivan Soll. I also offer a metaphysical reading of Schopenhauer’s claim that no amount happiness can compensate for the mere fact of suffering, based upon his negative conception of happiness. I proceed by analysing Schopenhauer’s criticisms of two prominent optimists, Leibniz and Rousseau. I attempt to salvage something of Schopenhauer’s counterargument against Leibniz that this is the worse of all possible worlds, and I also examine Schopenhauer’s claim that the optimistic metaphysics of a priori rationalistic philosophy cannot cope with the evidence of meaningless suffering. In the case of Rousseau, I interpret Schopenhauer’s brief objection to Rousseau’s assumption of original goodness, by means of an examination of Schopenhauer’s conception of the contrary doctrine, original sin. Next I consider the metaphysics of Schopenhauer’s account of eternal justice. After defending it against a number of objections, I argue that the nature of his version of eternal justice, which he admits constitutes a justification for suffering, does not conflict with the fact that he so strongly condemns Leibniz’s and Rousseau’s optimistic justifications for suffering. Finally I assess whether and to what extent Schopenhauer’s ethics of salvation are either pessimistic or optimistic. I conclude that the mere fact that salvation is possible is not necessarily a cause for optimism, but that Schopenhauer’s doctrine of salvation is made partly optimistic by the higher form of cognition that he describes as part of it. I also argue that Schopenhauer’s views on the essentially mystical nature of the state of salvation ultimately commit him to being neither positively optimistic nor positively pessimistic about salvation. I conclude overall with some brief remarks about the meaning of Schopenhauer’s pessimism, and how in spite of its diverse nature, it is able to lay down a singular challenge to all future philosophers concerned with the question of suffering.

Traditionally, the investigation of truth has been anchored in a priori reasoning. Cognitive science deviates from this tradition by adding empirical data on how people understand and use concepts. Building on psychophysics and machine learning methods, we introduce conceptual scaling, an approach to map people's understanding of abstract concepts. This approach, allows computing participant-specific conceptual maps from obtained ordinal comparison data, thereby quantifying perceived similarities among abstract concepts. Using this approach, we investigated individual's alignment with philosophical theories on truth and (...) the predictive capacity of conceptual maps. The obtained results indicated that, while people's understanding of truth is multifaceted and encapsulates notions of coherence and authenticity, alignment is best for the correspondence theory of truth. Furthermore, conceptual maps allowed predicting individual outcomes with an accuracy of roughly 70%. This research demonstrates that conceptual scaling offers accurate descriptions of individual's understanding of abstract concepts, behavioral predictions, and quantification of alignment with theoretical perspectives.

According to Brian Loar, an adequate theory of intentionality must acknowledge the fundamental role phenomenology plays in the determination of intentional content. It must take into account individuals’ experience of their intentional states, from a subjective point of view. From this perspective, intentional content is internally determined (given that phenomenology is). On the other hand, Loar is convinced (by arguments given by Tyler Burge) that mental states also have externally determined contents, fixed by objective facts about thinkers’ sociolinguistic environments. This (...) paper argues that Loar’s theory of intentionality is compromised by his acceptance of the Burgean intuitions (which do not, their power and influence notwithstanding, support anti-individualism) and by an overly narrow view of the scope of phenomenology.

The sense of balance remains a Cinderella among our senses. Although the vestibular apparatus and the apprehension of motion, equilibrium and orientation which it serves has now been studied extensively and descriptions abound in textbooks on perceptual psychology, its key role in our agency remains neglected in philosophical accounts of perception. Popularly received wisdom on the senses also largely ignores balance and it has recently even been called 'the lost sense'. -/- Recognition for the discovery of this sense should probably (...) be accorded to Thomas Reid and his contemporary William Charles Wells. Both made crucial observations before the close of the eighteenth century. Since there is now a tendency to emphasize the role of the agent, brain plasticity, and the development of motor skills in all perceptual tasks, some of Reid's comments in particular strike us as remarkably modern. Reid also differs from many authorities in crediting the sense with specific sensations, as would be expected given the role of sensations in his epistemological scheme. -/- In this paper some of the fascinating facts about the sense of balance are reviewed so that Reid's remarks can be evaluated in a modern context. Similarities and differences in the approaches of Wells and Reid are considered and the value that Reid's insights have even now in understanding perceptual processes is explored. It is suggested that Reid should indeed be counted among the hitherto unacknowledged discoverers of this fundamental sense. (shrink)

The principal thesis in this review-essay is that the key linguistic terms in Fichte’s Wissenschaftslehre especially have two main meanings that appear at first sight to be almost in contradiction or opposed to each other. The reader of Fichte therefore has to work hard to overcome any apparent conflicts in the “double sense” of his philosophical terminology. Accordingly, I argue that Fichte’s linguistic method and use of language should be seen as part of his chief philosophical method of synthesis, where (...) we have to carry out a similar procedure and attempt to reconcile opposites using the power of the imagination. This thesis is put forward by means of a number of practical examples and in the context of some critical reflections on the recently published Cambridge Companion to Fichte, eds. David James and Günter Zöller. Review essay published in Volume 15 (December, 2017) of the journal Revista de Estud(i)os sobre Fichte (ed. Emiliano Acosta). (shrink)

This chapter examines the ethical matters that arise from Schopenhauer’s discussions of sexual love and sexual practices. It presents Schopenhauer's remarks on “pederasty”, among other “unnatural lusts”, and attempts to disentangle Schopenhauer’s judgements on these practices from the principles that guide them. It considers these practices in the light of Schopenhauer's ethics of asceticism and his ethics of compassion and concludes that Schopenhauer’s objections to them are not always moral in nature, strictly speaking, and where they are moral, they are (...) not always based on the “unnaturalness” of the practices, but rather the harm that he supposes they may cause.

Plato's Phaedo is a literary gem that develops many of his most famous ideas. David Ebrey's careful reinterpretation argues that the many debates about the dialogue cannot be resolved so long as we consider its passages in relative isolation from one another, separated from their intellectual background. His book shows how Plato responds to his literary, religious, scientific, and philosophical context, and argues that we can only understand the dialogue's central ideas and arguments in light of its overall structure. (...) This approach yields new interpretations of the dialogue's key ideas, including the nature and existence of 'Platonic' forms, the existence of the soul after death, the method of hypothesis, and the contemplative ethical ideal. Moreover, this comprehensive approach shows how the characters play an integral role in the Phaedo's development and how its literary structure complements Socrates' views while making its own distinctive contribution to the dialogue's drama and ideas.

An overview of Kai Nielsen's philosophy focusing on his contributions to metaphilosophy and a critical theory based on wide reflective equilibrium, global justice, and egalitarianism.

In this paper I study how the theoretical categories of consumption theory were used by Milton Friedman in order to classify empirical data and obtain predictions. Friedman advocated a case by case definition of these categories that traded theoretical coherence for empirical content. I contend that this methodological strategy puts a clear incentive to contest any prediction contrary to our interest: it can always be argued that these predictions rest on a wrong classification of data. My conjecture is that this (...) methodological strategy can contribute to explain why Friedman’s predictions never generated the consensus he expected among his peers. (shrink)

I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the value (...) of inquiry. (shrink)

Also (...) included are new studies on the first principles of the particular sub-disciplines of Fichte’s system, such as the doctrines of aesthetics, nature, right, ethics, and history. The volume also contains a number of miscellaneous essays on Fichte research, as well as several book reviews. (shrink)

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

Evaluativism is best thought of as a way of enriching a perceptual view of pain to account for pain’s unpleasantness or painfulness. Once it was common for philosophers to contrast pains with perceptual experiences (McGinn 1982; Rorty 1980). It was thought that perceptual experiences were intentional (or content-bearing, or about something), whereas pains were representationally blank. But today many of us reject this contrast. For us, your having a pain in your toe is a matter not of your sensing “pain-ly” (...) or encountering a sense-datum, but of your having an interoceptive experience representing (accurately or inaccurately) that your toe is in a particular experience-independent condition, such as undergoing a certain “disturbance” or being damaged or in danger (Armstrong 1962; Tye 1995). But even if such representational content makes an experience a pain, a further ingredient seems required to make the pain unpleasant. According to evaluativism, the further ingredient is the experience’s possession of evaluative content: its representing the bodily condition as bad for the subject. In this chapter, I elaborate evaluativism, locate it among alternatives, and explain its attractions and challenges. (shrink)

Ralph Ellison consistently relied on a small set of terms in order to guide his writing practice and his interpretation of literature, history, and society. Following Kenneth Burke, an acquaintance of Ellison, I call this his terministic screen. Perhaps the most important elements of Ellison’s terministic screen are consciousness–conscience and purpose–passion–perception. The first set of terms represents what he saw as our democratic obligations: the pursuit of a progressively clearer consciousness of democratic ideals and a more refined conscientiousness in pursuing (...) these ideals. The second set of terms provided a narrative framework for showing how consciousness and conscience are attained or evaded. This essay analyzes the intellectual history of these terms and how they function in Ellison’s essays and novels. Special attention is given to Ellison’s unfinished second novel. (shrink)

The purpose of this essay is to shed some light on a certain type of sentence, which I call a borderline contradiction. A borderline contradiction is a sentence of the form F a ∧ ¬F a, for some vague predicate F and some borderline case a of F , or a sentence equivalent to such a sentence. For example, if Jackie is a borderline case of ‘rich’, then ‘Jackie is rich and Jackie isn’t rich’ is a borderline contradiction. Many theories (...) of vague language have entailments about borderline contradictions; correctly describing the behavior of borderline contradictions is one of the many tasks facing anyone offering a theory of vague language. Here, I first briefly review claims made by various theorists about these borderline contradictions, attempting to draw out some predictions about the behavior of ordinary speakers. Second, I present an experiment intended to gather relevant data about the behavior of ordinary speakers. Finally, I discuss the experimental results in light of several different theories of vagueness, to see what explanations are available. My conclusions are necessarily tentative; I do not attempt to use the present experiment to demonstrate that any single theory is incontrovertibly true. Rather, I try to sketch the auxiliary hypotheses that would need to be conjoined to several extant theories of vague language to predict the present result, and offer some considerations regarding the plausibility of these various hypotheses. In the end, I conclude that two of the theories I consider are better-positioned to account for the observed data than are the others. But the field of logically-informed research on people’s actual responses to vague predicates is young; surely as more data come in we will learn a great deal more about which (if any) of these theories best accounts for the behavior of ordinary speakers.

We often get reason to doubt the reliability of some of our own reasoning. The rational response to such evidence would seem to depend on how reliable one should estimate that reasoning to be. Independence principles constrain that reliability-assessment, to prevent question-begging reliance on the very reasoning being assessed. But this has consequences some find disturbing: can it be rational for an agent to bracket some of her reasons—which she may, after all, be assessing impeccably? So several arguments have been (...) offered against the very idea of an Independence principle. This paper argues that looking closely at these arguments actually strengthens the case for Independence, and yields some guidance in meeting a formidable challenge for Independence-defenders: formulating the principle in an adequate way.

Consequentialism, many philosophers have claimed, asks too much of us to be a plausible ethical theory. Indeed, the theory's severe demandingness is often claimed to be its chief flaw. My thesis is that as we come to better understand this objection, we see that, even if it signals or tracks the existence of a real problem for Consequentialism, it cannot itself be a fundamental problem with the view. The objection cannot itself provide good reason to break with Consequentialism, because it (...) must presuppose prior and independent breaks with the view. The way the objection measures the demandingness of an ethical theory reflects rather than justifies being in the grip of key anti-Consequentialist conclusions. We should reject Consequentialism independently of the Objection or not at all. Thus, we can reduce by one the list of worrisome fundamental complaints against Consequentialism. (shrink)

I argue that according to Socrates in the Phaedo we should not merely evaluate bodily pleasures and desires as worthless or bad, but actively avoid them. We need to avoid them because they change our values and make us believe falsehoods. This change in values and acceptance of falsehoods undermines the soul’s proper activity, making virtue and happiness impossible for us. I situate this account of why we should avoid bodily pleasures within Plato’s project in the Phaedo of providing Pythagorean (...) and Orphic ideas with clearer meanings and better justifications.

If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own reliability? After distinguishing between two kinds of epistemically illegitimate circularity—bootstrapping and self-verification—I argue for a qualified version of (...) the claim that there is nothing especially illegitimate about using a questionable source to evaluate its own reliability. Instead, it is illegitimate to appeal to a questionable source’s testimony on any matter whatsoever, with the matter of the source’s own reliability serving only as a special case. (shrink)

How should we understand knowledge-how – knowledge how to do something? And how is it related to knowledge-that – knowledge that something is the case? In this paper, I will discuss a very important and influential aspect of this question, namely the claim – dubbed ‘Intellectualism’ by Gilbert Ryle – that knowledge-how can be reduced to knowledge-that. Recently, Jason Stanley and Timothy Williamson have tried to establish Intellectualism with the aid of linguistic considerations. This project – Linguistic Intellectualism – will (...) be criticized on three levels. First, I will reconstruct and object to Stanley and Williamson’s positive argument in favour of Intellectualism. Second, I will assess their view of the relationship between knowledge-how and practical ability and argue that their stance is not well-motivated. Third, I will discuss their criticism of Ryle’s objection against Intellectualism. After distinguishing between different versions of Ryle’s argument, I will show that its strongest version is both immune to the objection by Stanley and Williamson and a decisive argument against their own theory. Given that Intellectualism fails for these three reasons, I finally draw on a broader reading of Ryle in order to develop the beginnings of a positive account of knowledge-how and its relationship to knowledge-that.

• Aggregates of previously isolated cells of Hydra are capable, under suitable solvant conditions, of regeneration forming complete animals. In a first stage, ecto- and endodermal cells sort out, producing the bilayered hollow structure characteristic of Hydra tissue; thereafter, heads are formed (even if the original cell preparation contained no head cells), eventually leading to the separation of normal animals with head, body column and foot. Hydra appears to be the highest type of organism that allows for regeneration of the (...) entire structure from random cell aggregates. The system is particularly useful for studying cell interactions, tissue polarity, pattern formation, and cell differentiation. (shrink)

Formally-inclined epistemologists often theorize about ideally rational agents--agents who exemplify rational ideals, such as probabilistic coherence, that human beings could never fully realize. This approach can be defended against the well-know worry that abstracting from human cognitive imperfections deprives the approach of interest. But a different worry arises when we ask what an ideal agent should believe about her own cognitive perfection (even an agent who is in fact cognitively perfect might, it would seem, be uncertain of this fact). Consideration (...) of this question reveals an interesting feature of the structure of our epistemic ideals: for agents with limited information, our epistemic ideals turn out to conflict with one another.

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality.
