This paper analyses the hidden use of new axioms in set-theoretic practice with a focus on large cardinal axioms and presents a general overview of set-theoretic practices using large cardinal axioms. The hidden use of a new axiom provides extrinsic reasons in support of this axiom via the idea of verifiable consequences, which is especially relevant for set-theoretic practitioners with an absolutist view. Besides that, the hidden use has pragmatic significance for further important sub-groups of the set-theoretic community---set-theoretic practitioners with (...) a pluralist view and set-theoretic practitioners who aim for ZFC-proofs. By describing this, the paper gives a more complete picture of new axioms in set-theoretic practice. These observations, for instance, show that set-theoretic practitioners interested in ZFC-proofs use tools that go beyond ZFC. The analysis is based on empirical data that was collected in an extensive interview study with set-theoretic practitioners. (shrink)

In arguing against the likelihood of consciousness in non-human animals, Descartes advances a slippery slope argument that if thought were attributed to any one animal, it would have to be attributed to all, which is absurd. This paper examines the foundations of Thomas Willis’ comparative neuroanatomy against the background of Descartes’ slippery slope argument against animal consciousness. Inspired by Gassendi’s ideas about the corporeal soul, Thomas Willis distinguished between neural circuitry responsible for reflex behaviour and that responsible for cognitively or (...) consciously mediated behaviour. This afforded Willis a non-arbitrary basis for distinguishing between animals with thought and consciousness and those without, a methodology which retains currency for neuroscience today. (shrink)

Kant’s notorious remark about the impossibility of there ever being a Newton of a blade of grass has often been interpreted as a misguided pre-emptive strike against Darwin and evolutionary theories in general: 'It would be absurd for humans even to make such an attempt or to hope that there may yet arise a Newton who could make comprehensible even the generation of a blade of grass according to natural laws that no intention has ordered; rather, we must absolutely deny (...) this insight to human beings. (CPJ 5:400) My aim in this chapter is to re-evaluate this claim in the context of Kant’s account of organic generation and argue that, contrary to what is usually thought, it does leave room for the possibility of evolution. After spelling out the constraints Kant identifies for any scientific study of the history of living beings, I examine his theory of generation and draw its implications for biological heredity, species diversity, and the role played by environmental factors in organic development. On this basis, I conclude that first, evolution is a possible albeit far-fetched hypothesis for Kant; second, Darwin’s theory of natural selection would have turned a far-fetched possibility into a plausible candidate; and third, it would not have disposed of the need for teleology. This is why, I argue, Darwin could never have been a Newton of a blade of grass. (shrink)

We live in a market system with much economic inequality. This may not be an essential characteristic of market systems but seems historically inevitable. How we should evaluate it, on the other hand, is contentious. I propose that bleeding heart libertarianism provides the best diagnosis and prescription.

Wes Morriston contends that William Lane Craig's argument for the impossibility of a beginningless past results in an equally good argument for the impossibility of an endless future. Craig disagrees. I show that Craig's reply reveals a commitment to an unmotivated position concerning the relationship between actuality and the actual infinite. I then assess alternative routes to the impossibility of a beginningless past that have been offered in the literature, and show that, contrary to initial appearances, these routes similarly seem (...) to support the impossibility of an endless future.

It is well-known that in the fifth of his Cartesian Meditations, Husserl puts forth a theory of intersubjectivity. Most commentators of Husserl have read his Cartesian Meditations as presenting a theory of intersubjectivity whose basis is empathy, in the form of a process of constituting the sense of “other” in one’s own experience, as the primary origin of the intersubjective layer of experience. In this paper, I claim that the structure of intersubjectivity as Husserl presents it in the Cartesian Meditations (...) is articulated as being governed by a logic of parts and wholes rather than that of a phenomenology of empathy, and that the articulation of this logic demonstrates that the transcendental ego is intrinsically intersubjective. My main philosophical claim in this regard is that the way Husserl’s account of transcendental empathy unfolds in the Cartesian Meditations implies a prior fundamental mereological structure of which the individual transcendental ego is only a part. That is, the transcendental ego has an eidetic a-priori intersubjective structure, in the sense of being a moment of an intersubjectively structured transcendental whole. In this sense, rather than being a singulare tantum, it is more fitting to say that transcendental subjectivity is actually a plurale tantum. (shrink)

I defend a neo-Kantian view wherein we are capable of being completely autonomous and impartial and argue that this ability can ground normativity. As this view includes an existentialist conception of the self, I defend radical choice, a primary component of that conception, against arguments many take to be definitive. I call the ability to use radical choice “existentialist voluntarism” and bring it into a current debate in normative philosophy, arguing that it allows that we can be distanced from all (...) ends at once so as to be completely impartial. Finally, I indicate how this can be the source of normativity as it provides a purely impartial reason for being rational. (shrink)

According to Kant, the opacity of human motivation takes two distinct forms – a psychological form: man ‘can never, even by the most strenuous self-examination, get entirely behind [his] covert incentives’ – and a social form: ‘everyone in our race finds it advisable to be on his guard, and not to reveal himself completely’. In other words, first, men's ‘interior’ cannot be entirely revealed to themselves and, second, they tend not to reveal their ‘interior’ to others. A number of Kant (...) scholars have acknowledged the importance of the first form of opacity in Kant's thought and have attempted to draw out from it implications for moral deliberation and ethics in general. The aim of this paper is to examine the second, social form of opacity and draw out its anthropological implications, an issue that has been overlooked in the literature. To do so, I focus on Kant's contrast between men and beings that I would like to call ‘sincere aliens’. These sincere aliens are beings who have the opposite features of man's opacity, namely beings who cannot but reveal their ‘interior’ both to others and to themselves. (shrink)

We explain libertarian thought about family and children, including controversial issues in need of serious attention. To begin our discussion of marriage, we distinguish between procedural and substantive contractarian approaches to marriage, each endorsed by various libertarians. Advocates of both approaches agree that it is a contract that makes a marriage, not a license, but disagree about whether there are moral limits to the substance of the contract with only advocates of the substantive approach accepting such. Either approach, though, offers (...) advantages over the current licensing system, so we discuss paths from that to a contractarian system. We also discuss the concept of marriage itself, the ages of consent for marriage, sexual activity, and reproduction, as well as how marriages can be dissolved, and coercion that sometimes occurs in marriage. We then turn to children. We first discuss reproductive freedom and then discuss the moral relationship between children and parents, especially considering stewardship, propertarian, and best interests approaches (we also touch on anti-natalism). One of the biggest issues facing parents is how to properly raise and educate children; we discuss this in depth and consider the sort of schooling that should be offered in a free society. Since children lack the requisite ability to consent, they cannot choose their education; how to respond to this is of the utmost importance for libertarians. As we note, the same issue of consent looms large for many forms medical treatment of children. (shrink)

Philosophers of language are increasingly engaging with derogatory terms or slurs. Only few theorists take such language as a starting point for addressing puzzles in philosophy of language with little connection to our real-world problems. This paper aims to show that the political nature of derogatory language use calls for non-ideal theorising as we find it in the work of feminist and critical race scholars. Most contemporary theories of slurs, so I argue, fall short on some desiderata associated with a (...) non-ideal approach. They neglect crucial linguistic or political aspects of morally and politically significant meaning. I argue that a two-stage project is necessary to understand the perniciousness of slurs: accounting for the derogatory content of derogatory terms in general and, additionally, explaining the communicative function of slurs more specifically. I end by showing how inferentialism is well-suited to account for the content of derogatory terms whilst allowing for further explanations of the communicative functions of slurs. (shrink)

Virtue, the centerpiece of ancient ethics, has come under attack by virtue skeptics impressed by results of psychology experiments including Milgram’s obedience studies. The virtue skeptic argues that experimental findings suggest that character structures are so fragile vis-à-vis situational factors as to be explanatorily superfluous: virtues and robust character traits are a myth, and should be replaced by situation-specific “narrow dispositions” (Gilbert Harman) or “local traits” (John Doris). This paper argues that the virtue skeptics’ sweeping claims are ill-founded. First, blending (...) Aristotelian and contemporary insights about virtue, I reach adecision about a reasonable, nonstraw defmition of “virtue” and of “character trait.” Next, I argue that explanations give by Lee Ross and Richard Nisbett for the Milgram findings covertly invoke character traits. Reflection reveals that more robust, crosssituationally consistent traits are needed for explanation of subject behavior, and that it is reasonable to suppose that such traits were in place.

There are different narratives on mathematics as part of our world, some of which are more appropriate than others. Such narratives might be of the form ‘Mathematics is useful’, ‘Mathematics is beautiful’, or ‘Mathematicians aim at theorem-credit’. These narratives play a crucial role in mathematics education and in society as they are influencing people’s willingness to engage with the subject or the way they interpret mathematical results in relation to real-world questions; the latter yielding important normative considerations. Our strategy is (...) to frame current narratives of mathematics from a virtue-theoretic perspective. We identify the practice of mathematizing, put forward by Freudenthal’s ‘Realistic mathematics education’, as virtuous and use it to evaluate different narratives. We show that this can help to render the narratives more adequately, and to provide implications for societal organization. (shrink)

Many philosophers in the field of meta-ethics believe that rational degrees of confidence in moral judgments should have a probabilistic structure, in the same way as do rational degrees of belief. The current paper examines this position, termed “moral Bayesianism,” from an empirical point of view. To this end, we assessed the extent to which degrees of moral judgments obey the third axiom of the probability calculus, ifP(A∩B)=0thenP(A∪B)=P(A)+P(B), known as finite additivity, as compared to degrees of beliefs on the one (...) hand and degrees of desires on the other. Results generally converged to show that degrees of moral judgment are more similar to degrees of belief than to degrees of desire in this respect. This supports the adoption of a Bayesian approach to the study of moral judgments. To further support moral Bayesianism, we also demonstrated its predictive power. Finally, we discuss the relevancy of our results to the meta-ethical debate between moral cognitivists and moral non-cognitivists. (shrink)

ABSTRACT: Virtue, the centerpiece of ancient ethics, has come under attack by virtue skeptics impressed by results of psychology experiments including Milgram's obedience studies. The virtue skeptic argues that experimental findings suggest that character structures are so fragile vis-å-vis situational factors as to be explanatorily superfluous: virtues and robust character traits are a myth, and should be replaced by situation-specific "narrow dispositions" (Gilbert Harman) or "local traits" (John Doris). This paper argues that the virtue skeptics' sweeping claims are ill-founded. First, (...) blending Aristotelian and contemporary insights about virtue, I reach a decision about a reasonable, non-straw definition of "virtue" and of "character trait." Next, I argue that explanations give by Lee Ross and Richard Nisbett for the Milgram findings covertly invoke character traits. Reflection reveals that more robust, cross-situationally consistent traits are needed for explanation of subject behavior, and that it is reasonable to suppose that such traits were in place.

This volume includes nineteen articles by scholars from Asia, North America, and Europe on Chinese thinkers from the eleventh to the eighteenth centuries. Included here are intellectual biographies of literati such as Zhou Dunyi, the Cheng brothers, Zhu Xi, Zhang Shi, Hu Hong, Wang Yangming, and Dai Zhen. Essays are arranged chronologically, and most begin with a biographical sketch of their subject. They provide variety rather than uniformity of approach, but all in all these essays are remarkably rich and offer (...) much new material on both familiar and lesser-known thinkers. (shrink)

The ji 己self is a site, storehouse, or depot of individuated allotment associated with the possession of things and qualities: wholesome and unwholesome desires (yu 欲) and aversions, emotions such as anxiety, and positive values such as humaneness and reverence. Each person's allotment is unique, and its "contents" are collected, measured, reflected on, and then distributed to others. The Analects, Mencius, Xunzi, Daodejing, and Zhuangzi each have their own vision for negotiating the space between self and other. Works as seemingly (...) dissimilar as the Analects and Daodejing both agree that positive qualities located within the self should be shared with others, and that the self can be optimized rather than maximized through sharing, emptying, or clearing. Sommer compares the ji self with other terms for body and person current in classical times. This self is strongly individuated, but it exists primarily in relation to other human beings (ren 人 ). These "others" are almost never one's own kind and are usually people who fall outside one's ascribed familial and social relationships. Negotiations between self and other often reflect apprehension regarding degrees of distance, intimacy, worth, recognition, or understanding (zhi 知) between people. (shrink)

Beyond “A Lecture on Ethics,” Wittgenstein says little on the topic of ethics, despite professing a great respect for ethics. I argue that while Wittgenstein ceases to speak of ethics, his account fits equally within his Tractarian and post-Tractarian writing. On both accounts of language, ethics remains nonsense, but it is not insignificant nonsense. However, because Wittgenstein holds ethics to concern absolute values that are in principle inexpressible, his anti-theoretical conception of ethics fails to offer guidance in how one ought (...) to live. That is, ethics ultimately cannot be show unless it can, in some sense, be said. (shrink)

While feminist philosophy has had much to say on the topic of reason, little has been done to develop a specifically feminist account of the concept. I argue for a virtue account of mind grounded in contemporary approaches to rationality. The evolutionary stance adopted within most contemporary theories of mind implicitly entails a rejection of central elements of Cartesianism. As a result, many accounts of rationality are anti-modern is precisely the sorts of ways that feminists demand. I maintain that a (...) virtue account of rationality can provide a satisfactory answer to Benhabib’s question in Situating of the Self: what concept of reason are we willing to defend? (shrink)

Feminist philosophy is highly critical of Cartesian, and more broadly Enlightenment, conceptions of rationality. However, feminist philosophers typically fail to address contemporary theories of rationality and to consider how more current thoeories address feminist concerns. I argue that, contrary to their protestations, feminists are “obsessing over an outdated conception of reason” and that even the most suspect of “malestream” philosophers express an understanding of rationality that is closer to feminist concerns than Cartesian ones. I begin by briefly examining key features (...) of Cartesian rationality and discuss how these features are largely rejected by contemporary philosophy and cognitve science. I then discuss how the philosophical accounts of Robert Nozick and Robert Audi refelect this rejection of Cartesian rationality. Finally, I discuss how the views of Nozick and Audi are in line with many feminist concerns, and I argue that feminists need to take seriously some theory of rationality. (shrink)

Although feminists have spilled a great deal of ink criticizing Enlightenment conceptions of rationality, the time has come to consider constructing a positive account. Recent attempts to construct an account of rationality as a virtue concept reflect many feminist complaints concerning Enlightenment rationality, and, thus, I maintain that feminism should take seriously such a conception. Virtue rationality offers a more diverse account of rationality without sacrificing the fundamental normativity of the concept. Furthermore, the narrower concept of reasonableness, promises to provide (...) a ground for distinguishing among better and worse epistemic perspectives, which is a task critical to the success of the feminist project.

This article examines the complaint that arbitrary algorithmic decisions wrong those whom they affect. It makes three contributions. First, it provides an analysis of what arbitrariness means in this context. Second, it argues that arbitrariness is not of moral concern except when special circumstances apply. However, when the same algorithm or different algorithms based on the same data are used in multiple contexts, a person may be arbitrarily excluded from a broad range of opportunities. The third contribution is to explain (...) why this systemic exclusion is of moral concern and to offer a solution to address it. (shrink)

The concept of acting intentionally is an important nexus where ‘theory of mind’ and moral judgment meet. Preschool children’s judgments of intentional action show a valence-driven asymmetry. Children say that a foreseen but disavowed side-effect is brought about 'on purpose' when the side-effect itself is morally bad but not when it is morally good. This is the first demonstration in preschoolers that moral judgment influences judgments of ‘on-purpose’ (as opposed to purpose influencing moral judgment). Judgments of intentional action are usually (...) assumed to be purely factual. That these judgments are sometimes partly normative — even in preschoolers — challenges current understanding. Young children’s judgments regarding foreseen side-effects depend upon whether the children process the idea that the character does not care about the side-effect. As soon as preschoolers effectively process the ‘theory of mind’ concept, NOT CARE THAT P, children show the side-effect effect.idea.. (shrink)

In this paper I look at three versions of the charge that liberalism’s emphasis on individuals is detrimental to community—that it encourages a pernicious disregard of others by fostering a particular understanding of the individual and the relation she has with her society. According to that understanding, individuals are fundamentally independent entities who only enter into relations by choice and society is seen as nothing more than a venture voluntarily entered into in order to better oneself. Communitarian critics argue that (...) since liberals neglect the degree to which individuals are dependent upon their society for their self-understanding and understanding of the good, they encourage individuals to maintain a personal distance from others in their society. The detrimental effect this distancing is said to have on communities is often called “asocial individualism” or “asocialism.” I argue that all three versions of the charge fail against liberalism and that liberalism—with its insistence on the normative import of individuals—is not detrimental to communities, but can actually foster strong communities.

In this paper, I argue that poet M. Nourbese Philip's Zong! allows us to radically rethink the possibility of historical restitution and recovery. The formal ideas in Zong!, I argue, imply a metaphysical and ontological revolution in the way memory and mnesic traces are to be conceived. The evidentiary status of the voices and narratives that Zong! retrieves cannot be certified by historical-epistemological conceptions of evidence but rather find their warrant in alternative, ontological (or hauntological) registers.

Deepfakes are algorithmically modified video and audio recordings that project one person’s appearance on to that of another, creating an apparent recording of an event that never took place. Many scholars and journalists have begun attending to the political risks of deepfake deception. Here we investigate other ways in which deepfakes have the potential to cause deeper harms than have been appreciated. First, we consider a form of objectification that occurs in deepfaked ‘frankenporn’ that digitally fuses the parts of different (...) women to create pliable characters incapable of giving consent to their depiction. Next, we develop the idea of ‘illocutionary wronging’, in which an individual is forced to engage in speech acts they would prefer to avoid in order to deny or correct the misleading evidence of a publicized deepfake. Finally, we consider the risk that deepfakes may facilitate campaigns of ‘panoptic gaslighting’, where many systematically altered recordings of a single person's life undermine their memory, eroding their sense of self and ability to engage with others. Taken together, these harms illustrate the roles that social epistemology and technological vulnerabilities play in human ethical life. (shrink)

In On Touching, Derrida commends philosopher Jean-Luc Nancy for ‘taking into account [the] plasticity and technicity “at the heart” of the “body proper.”’ Specifying the meaning of this plasticity and technicity, Derrida writes, the"[s]upplementarity of technical prosthetics originarily spaces out, defers, or expropriates all originary properness: there is no “the” sense of touch, there is no “originary” or essentially originary touching before it." What is ‘proper’ or ‘original’ to the body, it seems, is not any set of properties or capacities (...) – including sensorial or perceptual powers – but rather the ‘plastic and substitutive structure of prosthetics’, the very possibility of the body’s ‘technical’ supplementation.

Do facts about what an agent would freely do in certain circumstances at least partly determine any of her moral obligations? Actualists answer ‘yes’, while possibilists answer ‘no’. We defend two novel hybrid accounts that are alternatives to actualism and possibilism: Dual Obligations Hybridism and Single Obligation Hybridism. By positing two moral ‘oughts’, each account retains the benefits of actualism and possibilism, yet is immune from the prima facie problems that face actualism and possibilism. We conclude by highlighting one substantive (...) difference between our two hybrid accounts. (shrink)

In recent years, a new generation of activists has reinvigorated debate over the public commemorative landscape. While this debate is in no way limited to statues, it frequently crystallizes around public representations of historical figures who expressed support for the oppression of certain groups or contributed to their past or present oppression. In this paper, I consider what should be done about such representations. A number of philosophers have articulated arguments for modifying or removing public monuments. Joanna Burch-Brown (2017) grounds (...) her argument for removal in what I call the “honorific” function of such representations—the ways in which they express and tend to cultivate admiration for their subjects. In the first two sections of the paper, I develop a novel argument for modifying these representations based on this insight. I argue that leaving such representations unmodified in the public space tends to undermine the dignity of members of oppressed groups as well as their assurance that society and government are committed to their rights and constitutional entitlements. In the paper’s third section, I develop a “balancing test” for determining whether the relevant moral and pragmatic considerations favor making a particular representation inaccessible to the public, or recontextualizing it for public consumption. Unlike some of the existing philosophical treatments of honorific representations that focus on particular monuments, this balancing test is designed for general application to any honorific representation that satisfies the presumptive case for modification. To conclude, I offer some reasons why weak forms of recontextualization that do not involve altering institutional context may often be an insufficient remedy for the problems I describe. (shrink)

Molyneux's Question (MQ) concerns whether a newly sighted man would recognize/distinguish a sphere and a cube by vision, assuming he could previously do this by touch. We argue that (MQ) splits into questions about (a) shared representations of space in different perceptual systems, and about (b) shared ways of constructing higher dimensional spatiotemporal features from information about lower dimensional ones, most of the technical difficulty centring on (b). So understood, MQ resists any monolithic answer: everything depends on the constraints faced (...) by particular perceptual systems in extracting features of higher dimensionality from those of lower. Each individual question of this type is empirical and must be investigated separately. We present several variations on MQ based on different levels of dimensional integration—some of these are familiar, some novel adaptations of problems known elsewhere, and some completely novel. Organizing these cases in this way is useful because it unifies a set of disparate questions about intermodal transfer that have held philosophical and psychological interest, suggests a new range of questions of the same type, sheds light on similarities and differences between members of the family, and allows us to formulate a much-augmented set of principles and questions concerning the intermodal transfer of spatiotemporal organization.

Orthodox decision theory gives no advice to agents who hold two goods to be incommensurate in value because such agents will have incomplete preferences. According to standard treatments, rationality requires complete preferences, so such agents are irrational. Experience shows, however, that incomplete preferences are ubiquitous in ordinary life. In this paper, we aim to do two things: (1) show that there is a good case for revising decision theory so as to allow it to apply non-vacuously to agents with incomplete (...) preferences, and (2) to identify one substantive criterion that any such non-standard decision theory must obey. Our criterion, Competitiveness, is a weaker version of a dominance principle. Despite its modesty, Competitiveness is incompatible with prospectism, a recently developed decision theory for agents with incomplete preferences. We spend the final part of the paper showing why Competitiveness should be retained, and prospectism rejected. (shrink)

The motivational constraint on normative reasons says that a consideration is a normative reason for an agent to act only if it is logically possible for the agent to act for that reason, or at least to be moved so to act. The claim figures Zelig-like in philosophical debates about practical reasons: on hand, occasionally prominent, but never the focus of discussion. However, because it is entailed by a number of prominent views about normative reasons—including various forms of internalism and (...) some views that closely connect reasons to good practical reasoning—its truth or falsehood has important implications. Mark Schroeder (2007) and Julia Markovits (2014) have recently criticized the Motivational Constraint on the grounds of so-called “elusive reasons”: reasons for some agent to act that are such that it is logically impossible both that they are normative reasons for that agent and the agent is moved to act for those reasons. In response, a number of philosophers (Sinclair 2016; Ridge and McKeever 2012; Paakkunainen 2017) have attempted to reconcile blindspot reasons with the motivational constraint. My aim in this paper is to show that these conciliatory strategies fail to overcome the challenge posed by elusive reasons. First, I examine each strategy and argue that it unsuccessful on its own terms. Second, I adduce another type of elusive reason not heretofore discussed in the literature, and I argue that these strategies also cannot make this kind of reason consistent with the motivational constraint. Finally, I defend the existence of this kind of reason against an important objection. (shrink)

Virtue ethics is often understood as a rival to existing consequentialist, deontological, and contractualist views. But some have disputed the position that virtue ethics is a genuine normative ethical rival. This chapter aims to crystallize the nature of this dispute by providing criteria that determine the degree to which a normative ethical theory is complete, and then investigating virtue ethics through the lens of these criteria. In doing so, it’s argued that no existing account of virtue ethics is a complete (...) normative ethical view that rivals existing consequentialist, deontological, and contractualist views. Moreover, it is argued that one of the most significant challenges facing virtue ethics consists in offering an account of the right-making features of actions, while remaining a distinctively virtue ethical view.

Penelope Maddy’s Second Philosophy is one of the most well-known ap- proaches in recent philosophy of mathematics. She applies her second-philosophical method to analyze mathematical methodology by reconstructing historical cases in a setting of means-ends relations. However, outside of Maddy’s own work, this kind of methodological analysis has not yet been extensively used and analyzed. In the present work, we will make a first step in this direction.

Significant variations in the way objects appear across different viewing conditions pose a challenge to the view that they have some true, determinate color. This view would seem to require that we break the symmetry between multiple appearances in favor of a single variant. A wide range of philosophical and non-philosophical writers have held that the symmetry can be broken by appealing to daylight viewing conditions—that the appearances of objects in daylight have a stronger, and perhaps unique, claim to reveal (...) their true colors. In this note we argue that, whatever else its merits, this appeal to daylight is not a satisfactory answer to the problem posed by perceptual variation. (shrink)

According to many philosophers, psychological explanation canlegitimately be given in terms of belief and desire, but not in termsof knowledge. To explain why someone does what they do (so the common wisdom holds) you can appeal to what they think or what they want, but not what they know. Timothy Williamson has recently argued against this view. Knowledge, Williamson insists, plays an essential role in ordinary psychological explanation.Williamson's argument works on two fronts.First, he argues against the claim that, unlike knowledge, (...) belief is``composite'' (representable as a conjunction of a narrow and a broadcondition). Belief's failure to be composite, Williamson thinks, undermines the usual motivations for psychological explanation in terms of belief rather than knowledge.Unfortunately, we claim, the motivations Williamson argues against donot depend on the claim that belief is composite, so what he saysleaves the case for a psychology of belief unscathed.Second, Williamson argues that knowledge can sometimes provide abetter explanation of action than belief can.We argue that, in the cases considered, explanations that cite beliefs(but not knowledge) are no less successful than explanations that citeknowledge. Thus, we conclude that Williamson's arguments fail both coming andgoing: they fail to undermine a psychology of belief, and they fail tomotivate a psychology of knowledge. (shrink)

Review of John Kekes' *A Case for Conservatism*.

Feynman's sum-over-histories formulation of quantum mechanics has been considered a useful calculational tool in which virtual Feynman histories entering into a coherent quantum superposition cannot be individually measured. Here we show that sequential weak values, inferred by consecutive weak measurements of projectors, allow direct experimental probing of individual virtual Feynman histories, thereby revealing the exact nature of quantum interference of coherently superposed histories. Because the total sum of sequential weak values of multitime projection operators for a complete set of orthogonal (...) quantum histories is unity, complete sets of weak values could be interpreted in agreement with the standard quantum mechanical picture. We also elucidate the relationship between sequential weak values of quantum histories with different coarse graining in time and establish the incompatibility of weak values for nonorthogonal quantum histories in history Hilbert space. Bridging theory and experiment, the presented results may enhance our understanding of both weak values and quantum histories. (shrink)

To enable microbial colonisation of the gut mucosa, the intestinal immune system must not only react to danger signals but also recognize cues that indicate safety. Safety recognition, paradoxically, is mediated by the same environmental sensors that are involved in signalling danger. Indeed, in addition to their well established role in inducing inflammation in response to stress signals, pattern recognition receptors (PRRs) and a variety of metabolic sensors also promote gut-microbiota symbiosis by responding to "microbial symbiosis factors", "resolution-associated molecular patterns", (...) markers of energy extraction and other signals indicating the absence of pathogenic infection and tissue damage. Here we focus on how the paradoxical role of immune receptors and other environmental sensors define the microbiota signature of the individual. (shrink)

How children seek knowledge and evaluate claims may depend on their understanding of the source of knowledge. What shifts in their understandings about why scientists might disagree and how claims about the state of the world are justified? Until about the age of 41/2, knowledge is seen as self-evident. Children believe that knowledge of reality comes directly through our senses and what others tell us. They appeal to these external sources in order to know. The attainment of Theory of Mind (...) (ToM) at this age is commonly seen as the significant shift in development in understanding disagreements in knowledge claims. Children attaining ToM understand that someone exposed to incorrect or incomplete information might have false beliefs. Disagreement, then, is still attributed to objective sources of knowledge. The current study examines the later developing Interpretive Theory of Mind (iToM) as the basis for children’s understanding of how people with access to the same information might disagree and what this means for how to provide justification for a knowledge claim. Fourteen 2nd graders with the most iToM responses to four tasks and 14 with the fewest iToM responses were selected from a larger sample of 91. In analyses of interviews about a story in which two experts make different claims about a scientific phenomenon, those in the high iToM group noted subjective perspective and processes as the source of disagreement and suggested the need for investigation as the means to knowing. In contrast, those in the low iToM group mostly could not explain the source of disagreement and held that knowledge is acquired from external sources. A comparison of the interviews regarding the science story 2 years later allows for a qualitative description of the development. Those in the low iToM group showed more general recognition of subjective and constructive processes in knowing whereas those in the high iToM group identified interpretive processes and the relativity of perspectives with implications for how observations were conducted and interpreted. Only those in the high iToM group referred to the importance of evidence as a basis for knowledge claims at either point in the study. (shrink)
