Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic issues arising from informed (...) disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (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)

This paper articulates a way to ground a relatively high prior probability for grand explanatory theories apart from an appeal to simplicity. I explore the possibility of enumerating the space of plausible grand theories of the universe by using the explanatory properties of possible views to limit the number of plausible theories. I motivate this alternative grounding by showing that Swinburne’s appeal to simplicity is problematic along several dimensions. I then argue that there are three plausible grand views—theism, atheism, and (...) axiarchism—which satisfy explanatory requirements for plausibility. Other possible views lack the explanatory virtue of these three theories. Consequently, this explanatory grounding provides a way of securing a nontrivial prior probability for theism, atheism, and axiarchism. An important upshot of my approach is that a modest amount of empirical evidence can bear significantly on the posterior probability of grand theories of the universe. (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)

It is a widespread intuition that the coherence of independent reports provides a powerful reason to believe that the reports are true. Formal results by Huemer, M. 1997. “Probability and Coherence Justification.” Southern Journal of Philosophy 35: 463–72, Olsson, E. 2002. “What is the Problem of Coherence and Truth?” Journal of Philosophy XCIX : 246–72, Olsson, E. 2005. Against Coherence: Truth, Probability, and Justification. Oxford University Press., Bovens, L., and S. Hartmann. 2003. Bayesian Epistemology. Oxford University Press, prove that, under (...) certain conditions, coherence cannot increase the probability of the target claim. These formal results, known as ‘the impossibility theorems’ have been widely discussed in the literature. They are taken to have significant epistemic upshot. In particular, they are taken to show that reports must first individually confirm the target claim before the coherence of multiple reports offers any positive confirmation. In this paper, I dispute this epistemic interpretation. The impossibility theorems are consistent with the idea that the coherence of independent reports provides a powerful reason to believe that the reports are true even if the reports do not individually confirm prior to coherence. Once we see that the formal discoveries do not have this implication, we can recover a model of coherence justification consistent with Bayesianism and these results. This paper, thus, seeks to turn the tide of the negative findings for coherence reasoning by defending coherence as a unique source of confirmation. (shrink)

The coherence of independent reports provides a strong reason to believe that the reports are true. This plausible claim has come under attack from recent work in Bayesian epistemology. This work shows that, under certain probabilistic conditions, coherence cannot increase the probability of the target claim. These theorems are taken to demonstrate that epistemic coherentism is untenable. To date no one has investigated how these results bear on different conceptions of coherence. I investigate this situation using Thagard’s ECHO model of (...) explanatory coherence. Thagard’s ECHO model provides a natural representation of the evidential significance of multiple independent reports. (shrink)

Why are we conscious? What does consciousness enable us to do that cannot be done by zombies in the dark? This paper argues that introspective consciousness probably co-evolved as a "spandrel" along with our more useful ability to represent the mental states of other people. The first part of the paper defines and motivates a conception of consciousness as a kind of "double vision" – the perception of how things seem to us as well as what they are – along (...) lines recently explored by Peter Carruthers. The second part explains the basic socioepistemic function of consciousness and suggests an evolutionary pathway to this cognitive capacity that begins with predators and prey. The third part discusses the relevance of these considerations to the traditional problem of other minds. (shrink)

Prerequisite to memory is a past distinct from present. Because wave evolution is both continuous and time-reversible, the undisturbed quantum system lacks a distinct past and therefore the possibility of memory. With the quantum transition, a reversibly evolving superposition of values yields to an irreversible emergence of definite values in a distinct and transient moment of time. The succession of such moments generates an irretrievable past and thus the possibility of memory. Bohm’s notion of implicate and explicate order provides a (...) conceptual basis for memory as a general feature of nature akin to gravity and electromagnetism. I propose that natural memory is an outcome of the continuity of implicate time in the context of discontinuous explicate time. Among the ramifications of natural memory are that laws of nature can propagate through time much like habits and that personal memory does not require neural information storage. (shrink)

By deriving the Lorentz transformation from the absolute speed of light, Einstein demonstrated the relativistic variability of space and time, enabling him to explain length contraction and time dilation without recourse to a "luminiferous ether" or preferred frame of reference. He also showed that clocks synchronized at a distance via light signals are not synchronized in a frame of reference differing from that of the clocks. However, by mislabeling the relativity of synchrony the "relativity of simultaneity," Einstein implied that this (...) effect concerns an actual difference in times from one frame to another rather than merely a failure of clock synchronization across frames. As a theory of length contraction and time dilation on the basis of relative motion in the context of the absolute speed of light, special relativity is the definitive interpretation of the Lorentz transformation and the correct explanation of relativistic phenomena. The relativity of simultaneity, as I demonstrate, plays no role in this explanation but instead provides apparent justification for a view of time in which the present moment is frame-dependent. In contrast to its legitimate application, special relativity fails as a theory of time on the basis of the relativity of simultaneity. (shrink)

The problem of biological memory led Russell to propose the existence of mnemic causation, a mechanism by which past experience influences current thought directly, that is, without the need for a material intermediary in the form of a neural "memory trace." Russell appears to have been inspired by German biologist Richard Semon's concept of mnemic homophony, which conveys memory to consciousness on the basis of similarity between current and past circumstances. Semon, however, in no way denied a role for stable (...) neural structures or "engrams" in the memory process. In contrast to Russell, contemporary biologist Rupert Sheldrake provides a viable theory of memory by remaining true to Semon's original idea and expanding it beyond personal memory to the collective memory of species, encompassing not only mental but developmental memory.

Conclusion: The present results support adequate psychometric properties in terms of factorial validity, reliability, convergent validity, and measurement invariance for the PHQ-4 in young adults in Hong Kong. The PHQ-4 demonstrated a substantial mediating role in the relationship between meaning in life and SI in the distress group. These findings support clinical relevance for using the PHQ-4 as a brief and valid measure of psychological distress in the Chinese context.

Suppositions can be introduced in either the indicative or subjunctive mood. The introduction of either type of supposition initiates judgments that may be either qualitative, binary judgments about whether a given proposition is acceptable or quantitative, numerical ones about how acceptable it is. As such, accounts of qualitative/quantitative judgment under indicative/subjunctive supposition have been developed in the literature. We explore these four different types of theories by systematically explicating the relationships canonical representatives of each. Our representative qualitative accounts of indicative (...) and subjunctive supposition are based on the belief change operations provided by AGM revision and KM update respectively; our representative quantitative ones are offered by conditionalization and imaging. This choice is motivated by the familiar approach of understanding supposition as `provisional belief revision' wherein one temporarily treats the supposition as true and forms judgments by making appropriate changes to their other opinions. To compare the numerical judgments recommended by the quantitative theories with the binary ones recommended by the qualitative accounts, we rely on a suitably adapted version of the Lockean thesis. Ultimately, we establish a number of new results that we interpret as vindicating the often-repeated claim that conditionalization is a probabilistic version of revision, while imaging is a probabilistic version of update.

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)

When you and I seriously argue over whether a man of seventy is old enough to count as an "old man", it seems that we are appealing neither to our own separate standards of oldness nor to a common standard that is already fixed in the language. Instead, it seems that both of us implicitly invoke an ideal, shared standard that has yet to be agreed upon: the place where we ought to draw the line. As with other normative standards, (...) it is hard to know whether such borderlines exist prior to our coming to agree on where they are. But epistemicists plausibly argue that they must exist whether we ever agree on them or not, as this provides the only logically acceptable response to the sorites paradox. This paper argues that such boundaries do typically exist as hypothetical ideals, but not as determinate features of the present actual world. There is in fact no general solution to the paradox, but attention to practice in resolving vague disagreements shows that its instances can be dealt with separately, as they arise, in many reasonable ways.

Alex Worsnip's recent book, Fitting Things Together: Coherence and the Demands of Structural Rationality, provides a sustained, wide-ranging defence of dualism.

In this paper I defend two closely related claims. The first claim, to which the first section of the paper is devoted, is that for Kant taste is a sort of cognition, that is, a form of awareness of reality for which questions of justification are appropriate. Nevertheless, In our appreciation of natural beauty we are aware of the suitability of appearances for inclusion in a rational system, albeit in a way that is subject to important limitations in comparison with (...) scientific cognition. In the second section of the paper, I will use this reading of Kant’s theory of taste to throw new light on Kant’s account of genius later in the “Critique of Aesthetic Judgment.”. (shrink)

By eliminating the need for an absolute frame of reference or ether, Einstein resolved the problem of the constancy of light-speed in all inertial frames but created a new problem in our understanding of time. The resolution of this problem requires no experimentation but only a careful analysis of special relativity, in particular the relativity of simultaneity. This concept is insufficiently relativistic insofar as Einstein failed to recognize that any given set of events privileges the frame in which the events (...) occur; relative to those events, only the privileged frame yields the correct measurement. Instead of equally valid frames occupying different times, one frame is correct and all others incorrect within a shared present moment. I conclude that (1) time is a succession of universal moments and (2) in the context of flowing time, time dilation requires absolute simultaneity, whereas relative simultaneity predicts a nonexistent phenomenon here dubbed time regression.

Fears of black-box algorithms are multiplying. Black-box algorithms are said to prevent accountability, make it harder to detect bias and so on. Some fears concern the epistemology of black-box algorithms in medicine and the ethical implications of that epistemology. In ‘Who is afraid of black box algorithms? On the epistemological and ethical basis of trust in medical AI,' Durán and Jongsma seek to allay such fears. While some of their arguments are compelling, we still see reasons for fear.

The quantum measurement problem resolves according to the twofold nature of time. Whereas the continuous evolution of the wave function reflects the fundamental nature of time as continuous presence, the collapse of the wave function indicates the subsidiary aspect of time as the projection of instantaneity from the ongoing present. Each instant irreversibly emerges from the reversible temporal continuum implicit in the smoothly propagating wave function. The basis of this emergence is periodic conflict between quantum systems, the definitive resolution of (...) which requires the momentary reduction of each system from the potentially infinite dimensions of configuration space to the three dimensions of classical space at an instant.

An atom is characterized mathematically as an evolving superposition of possible values of properties and experimentally as an instantaneous phenomenon with a precise value of a measured property. Likewise, an organism is to itself a flux of experience and to an observer a tangible body in a distinct moment. Whereas the implicit atom is the stream of computation represented by the smoothly propagating wave function, the implicit organism is both the species from which the body individuates and the personal mind (...) its behavior explicates. As with the wave computation that underlies the atom, the substance of the implicit organism is not matter but information. And like projection from a superposition of potential values to a single outcome in a precise and fleeting moment, the organism actualizes only one of the many possible behaviors calculated in the ongoing presence we know as consciousness. (shrink)

Because an unmeasured quantum system consists of information — neither tangible existence nor its complete absence — no property can be assigned a definite value, only a range of likely values should it be measured. The instantaneous transition from information to matter upon measurement establishes a gradient between being and not-being. A quantum system enters a determinate state in a particular moment until this moment is past, at which point the system resumes its default state as an evolving superposition of (...) potential values of properties, neither strictly being nor not-being. Like a “self-organized” chemical system that derives energy from breaking down environmental gradients, a quantum system derives information from breaking down the ontological gradient. An organism is a body in the context of energy and a mind in the context of information. (shrink)

The foundation of irreversible, probabilistic time -- the classical time of conscious observation -- is the reversible and deterministic time of the quantum wave function. The tendency in physics is to regard time in the abstract, a mere parameter devoid of inherent direction, implying that a concept of real time begins with irreversibility. In reality time has no need for irreversibility, and every invocation of time implies becoming or flow. Neither symmetry under time reversal, of which Newton was well aware, (...) nor the absence of an absolute parameter, as in relativity, negates temporal passage. Far from encapsulating time, irreversibility is a secondary property dependent on the emergence of distinct moments from the ceaseless presence charted by the wave function. (shrink)

Though Einstein explained time dilation without recourse to a universal frame of reference, he erred by abolishing universal present moments. Relative simultaneity is insufficiently relativistic insofar as it depends on the absolute equality of reference frames in the measurement of the timing of events. Yet any given set of events privileges the frame in which the events take place. Relative to those events, the privileged frame yields the correct measurement of their timing while all other frames yield an incorrect measurement. (...) Instead of multiple frames occupying multiple times, one frame is correct and all others incorrect within a shared present moment. With the collapse of relative simultaneity, we may regard time as a succession of universal moments. Absolute simultaneity, in turn, explains why an accelerated inertial frame dilates in time rather than regressing to a prior moment relative to non-accelerated frames. In the context of flowing time, absolute simultaneity predicts time dilation while relative simultaneity predicts time regression. Einstein's explanation of time dilation is therefore incomplete.

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)

Bradford Hill (1965) highlighted nine aspects of the complex evidential situation a medical researcher faces when determining whether a causal relation exists between a disease and various conditions associated with it. These aspects are widely cited in the literature on epidemiological inference as justifying an inference to a causal claim, but the epistemological basis of the Hill aspects is not understood. We offer an explanatory coherentist interpretation, explicated by Thagard's ECHO model of explanatory coherence. The ECHO model captures the complexity (...) of epidemiological inference and provides a tractable model for inferring disease causation. We apply this model to three cases: the inference of a causal connection between the Zika virus and birth defects, the classic inference that smoking causes cancer, and John Snow’s inference about the cause of cholera.

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.

Johann Georg Hamann's "Metakritik über den Purismum der Vernunft" begins with an allusion to Hume's endorsement of Berkeley's rejection of abstract ideas. On the basis of a close examination of the text of the Metakritik, I show that Hamann's overall point is that Kant cannot, or anyway does not, justify the relation of his own linguistic framework to natural language. Thus the Critique cannot meet its own standard for critical self-examination.

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)

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)

AI-supported methods for identifying and combating disinformation are progressing in their development and application. However, these methods face a litany of epistemic and ethical challenges. These include (1) robustly defining disinformation, (2) reliably classifying data according to this definition, and (3) navigating ethical risks in the deployment of countermeasures, which involve a mixture of harms and benefits. This paper seeks to expose and offer preliminary analysis of these challenges.

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.

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)
