Photons deliver their energy and momentum to a point on a material target. It is commonplace to attribute this to particle impact. But since the in-flight photon also has a wave nature, we are stuck with the paradox of wave-particle duality. It is argued here that the photon’s wave nature is indisputable, but its particle nature is open to question. Photons deliver energy. The problem with invoking impact as a means of delivery is that energy becomes a payload which in (...) turn requires a particle. This assumes that energy is always a payload and there is but one mode of energy delivery; surely two unsupported assumptions. It should be possible to explain photon termination without invoking particle impact. One approach offered here is to question the assumption that the photon is a unitary object. Perhaps the photon has two linked-but-distinct identities: one supporting wave behavior and the other supporting discrete behavior. It is the latter that might imitate particle impact. (shrink)

The Mach-Zehnder Interferometer (MZI) is chosen to illustrate the long-standing wave-particle duality problem. Why is which-way (welcher weg) information incompatible with wave interference? How do we explain Wheeler’s delayed choice experiment? Most crucially, how can the photon divide at the first beam splitter and yet terminate on either arm with its undiminished energy? The position advanced is that the photon has two identities, one supporting particle features and the other wave features. There is photon kinetic energy that never splits (on (...) half-silvered mirrors) or diffracts (in pinholes or slits). Then there are photon probability waves that do diffract and can reinforce or cancel. Photon kinetic energy is oscillatory; its cycles require/occupy time. E = mc2 suggests that kinetic energy is physically real as occurrence in time just as rest mass is physically real as existence in space; both are quantized and both occupy/require a dimension for their occurrence or existence. Photon kinetic energy (KE) thus resides in time, but is still present/available for interactions (events) in space; rest mass (e.g., your desk) resides in space but is still present/available for interactions (events) in time. While photon probability waves progress in space and diffract there, photon KE resides in time and never diffracts in space; at reception it always arrives whole and imitates particle impact without being a particle. Photon probability waves are real; they diffract in space. Acknowledging that the photon has two identities (residing energy and progressing probability), explains photon dual nature. And wave-particle duality is central to quantum mechanics. Understanding it leads to new insights into entanglement, nonlocality and the measurement problem. A 30-minute video on nonlocality and photon dualism can be found by a google: search “youtube klevgard nonlocality”). (shrink)

Particles and photons appear to be total opposites; the former has rest mass which requires space to exist; the latter has kinetic energy which requires time to occur (oscillate). But they do share certain properties (e.g., quantization) that remain invariant when one is transformed (swapped) for the other. This gauge invariance is developed in some detail. The symmetry between particle and photon turns out to be one of inversion. It is the equalities of special relativity that support this inversion and (...) the accompanying invariances: mass transformed to energy; space transformed to time. The great advantage of these symmetries (inversions) is that they provide guidance for an object little understood (the photon) based upon an object well understood (the particle). On this basis, progress can be made in the understanding of some long-standing issues: wave-particle duality, time’s arrow, the constant speed of light and nonlocality. (shrink)

The photon is typically regarded as a unitary object that is both particle-discrete and wave-continuous. This is a paradoxical position and we live with it by making dualism a fundamental feature of radiation. It is argued here that the photon is not unitary; rather it has two identities, one supporting discrete behavior and the other supporting continuous (wave) behavior. There is photon kinetic energy that is always discrete/localized on arrival; it never splits (on half-silvered mirrors) or diffracts (in pinholes or (...) slits). Then there is the photon’s probability wavefront that is continuous and diffractable. Acknowledging that the photon has two identities explains the photon’s dual nature. And wave-particle duality is central to quantum mechanics. Understanding it leads to new insights into the photon’s constant velocity and its entanglement with another photon. (shrink)

Radiation was a big challenge for the quantum pioneers since the photon was massless, probabilistic and appeared to be both wave and particle. Einstein’s special relativity equated mass with energy and space with time. But the equality of mass with energy, then and now, is regarded as quantitative and the equality of space with time is anything but equal; space hosts material entities; time hosts nothing. Exploring these equality issues raises some questions as to how measurable entities – particles and (...) photons – depend upon dimensions. The particle resides in a dimension, space, while also progressing (or persisting) in a dimension, time. The photon certainly progresses in one dimension, space; does it reside there as well? These questions lead to some new conclusions regarding the nature of the photon, its dualism and its nonlocal behavior. (shrink)

We think of kinetic energy (KE) as a quantity possessed by rest mass in motion. But somehow electromagnetic (EM) radiation transports KE across space without any rest mass. In addition, a single photon passing through a double slit diffracts into multiple paths in space without affecting its KE. This is hard to explain. Quantum theories that confront the double slit problem do not address these two issues directly. The ontology of radiation KE is examined which leads to some new ideas (...) as to the nature of KE transmission by radiation. (shrink)

Part I looks at duality for the photon; Part II does the same for the electron. The traditional division of kinetic energy between radiation and matter-in-motion is reexamined permitting new insights into duality. An in-flight photon displays wave characteristics. Such a photon can interfere with itself and take all available space paths as a wave. In addition, photons pass through one another like waves whereas particles impact each other. It is only when the photon terminates on a material object and (...) gives up its energy – and ceases to be a photon – that particle characteristics appear, namely: 1) the photon is finally space located; and 2) oscillation ceases. This suggests that the photon’s wave and particle nature do not overlap. Understanding photon termination as a release of mass stored, rather than particle impact, permits a better understanding of presumed wave-particle duality for the photon. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

Bernard Williams identifies Hume as “in some ways an archetypal reconciler” who, nevertheless, displays “a striking resistance to some of the central tenets of what [Williams calls] ‘morality’”. This assessment, it is argued, is generally correct. There are, however, some significant points of difference in their views concerning moral responsibility. This includes Williams’s view that a naturalistic project of the kind that Hume pursues is of limited value when it comes to making sense of “morality’s” illusions about responsibility and blame. (...) It is, Williams maintains, only when we consider moral responsibility in genealogical terms, which gives attention to the importance of culture and history, that we can find a way of exposing the various prejudices and illusions of “the morality system”. Nevertheless, despite these differences, what Hume and Williams share is a fundamental commitment to provide a more “truthful” and “realistic” understanding of moral responsibility and our human ethical predicament.

A survey of recent literature would suggest that Aristotle has become a whipping boy for philosophers who would advocate equality between the sexes. What I hope to show is that we can actually advance the cause of sexual equality by treating him more judiciously. Aristotle does argue that men and women by nature have different psychologies, and even that men are psychologically superior to women. But contrary to what many today think he himself does not conclude from this proposition that (...) men and women ought to have roles entirely different within a city. Indeed, he leaves ample room in his theory for women to participate in political rule. We shall see by his own arguments that all women ought to have a vote in general assemblies, and that some women ought to hold high political office. (shrink)

Extant theoretical work on the political resource curse implies that dependence on resource revenues should decrease autocracies’ likelihood of democratizing but not necessarily affect democracies’ chances of survival. Yet most previous empirical studies estimate models that are ill-suited to address this claim. We improve upon earlier studies, estimating a dynamic logit model that interacts a continuous measure of resource dependence with an indicator of regime type using data from 166 countries, covering the period from 1816-2006. We find that an increase (...) in resource dependence at time t - 1 increases the likelihood of autocratic persistence at t, but has no appreciable effect on democratic survival. We go beyond existing empirical studies to show that increases in resource dependence have persistent and substantial cumulative effects on autocracies' likelihood of becoming democratic over the long-term, showing that the total effect of resource dependence on regime type is much larger than the short-term (one period) effect indicates.

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

The Gamer’s Dilemma is based on the intuitions that in single-player video games fictional acts of murder are seen as morally acceptable whereas fictional acts of sexual assault are seen as morally unacceptable. Recently, it has been suggested that these intuitions may apply across different forms of media as part of a broader Paradox of Fictionally Going Too Far. This study aims to empirically explore this issue by determining whether fictional murder is seen as more morally acceptable than fictional sexual (...) assault across different media types, and whether audio-visuality and the degree of agency afforded by the medium influences these judgments. An experimental survey study was developed where participants responded to imaginary fictional scenarios as part of a 2 (engages with fictional murder or fictional sexual assault) X 2 (in a high or low agency) X 2 (audio-visual or non-audio-visual medium) factorial design. It was found that fictional murder was seen to be more morally acceptable than fictional sexual assault across all media types, providing empirical support for the Paradox of Fictionally Going Too Far. It was also found that the audio-visuality and degree of agency influenced judgments of moral acceptability. (shrink)

Overview of fundamental work in deontic logic.

It is one thing to hold that merely statistical evidence is _sometimes_ insufficient for rational belief, as in typical lottery and profiling cases. It is another thing to hold that merely statistical evidence is _always_ insufficient for rational belief. Indeed, there are cases where statistical evidence plainly does justify belief. This project develops a dispositional account of the normativity of statistical evidence, where the dispositions that ground justifying statistical evidence are connected to the goals (= proper function) of objects. There (...) are strong intuitive motivations for doing this. For we can turn almost any case of _non-justifying_ merely statistical evidence into a case of _justifying_ merely statistical evidence by adding information about the dispositions and goals of the objects involved. The resulting view not only helps us understand when and why merely statistical evidence is normatively significant, but it also helps us understand how statistical evidence relates to more standard forms of evidence (perceptual, testimonial). The emerging view also has surprising applications, as it imposes limitations on the epistemic value of fine-tuning arguments for theism as well as undermines a standard class of case-based arguments for moral encroachment.

Suppose some person 'A' sets out to accomplish a difficult, long-term goal such as writing a passable Ph.D. thesis. What should you believe about whether A will succeed? The default answer is that you should believe whatever the total accessible evidence concerning A's abilities, circumstances, capacity for self-discipline, and so forth supports. But could it be that what you should believe depends in part on the relationship you have with A? We argue that it does, in the case where A (...) is yourself. The capacity for "grit" involves a kind of epistemic resilience in the face of evidence suggesting that one might fail, and this makes it rational to respond to the relevant evidence differently when you are the agent in question. We then explore whether similar arguments extend to the case of "believing in" our significant others -- our friends, lovers, family members, colleagues, patients, and students. (shrink)

In this chapter, we analyze the relationships between the Internet and its users in terms of situated cognition theory. We first argue that the Internet is a new kind of cognitive ecology, providing almost constant access to a vast amount of digital information that is increasingly more integrated into our cognitive routines. We then briefly introduce situated cognition theory and its species of embedded, embodied, extended, distributed and collective cognition. Having thus set the stage, we begin by taking an embedded (...) cognition view and analyze how the Internet aids certain cognitive tasks. After that, we conceptualize how the Internet enables new kinds of embodied interaction, extends certain aspects of our embodiment, and examine how wearable technologies that monitor physiological, behavioral and contextual states transform the embodied self. On the basis of the degree of cognitive integration between a user and Internet resource, we then look at how and when the Internet extends our cognitive processes. We end this chapter with a discussion of distributed and collective cognition as facilitated by the Internet. (shrink)

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...) of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)

According to many, to have epistemic justification to believe P is just for it to be epistemically permissible to believe P. Others think it is for believing P to be epistemically good. Yet others think it has to do with being epistemically blameless in believing P. All such views of justification encounter problems. Here, a new view of justification is proposed according to which justification is a kind of composite normative status. The result is a view of justification that offers (...) hope of solving some longstanding epistemological problems. (shrink)

JOURNAL OF THE HISTORY OF PHILOSOPHY PRIZE for the best published book in the history of philosophy [Awarded in 2010] _______________ -/- Although it is widely recognized that David Hume's A Treatise of Human Nature (1739-40) belongs among the greatest works of philosophy, there is little agreement about the correct way to interpret his fundamental intentions. It is an established orthodoxy among almost all commentators that skepticism and naturalism are the two dominant themes in this work. The difficulty has been, (...) however, that Hume's skeptical arguments and commitments appear to undermine and discredit his naturalistic ambition to contribute to "the science of man". This schism appears to leave his entire project broken-backed. The solution to this riddle depends on challenging another, closely related, point of orthodoxy: namely, that before Hume published the Treatise he removed almost all material concerned with problems of religion. Russell argues, contrary to this view, that irreligious aims and objectives are fundamental to the Treatise and account for its underlying unity and coherence. It is Hume's basic anti-Christian aims and objectives that serve to shape and direct both his skeptical and naturalistic commitments. When Hume's arguments are viewed from this perspective we can solve, not only puzzles arising from his discussion of various specific issues, we can also explain the intimate and intricate connections that hold his entire project together. This "irreligious" interpretation provides a comprehensive fresh account of the nature of Hume's fundamental aims and ambitions in the Treatise. It also presents a radically different picture of the way in which Hume's project was rooted in the debates and controversies of his own time, placing the Treatise in an irreligious or anti-Chrisitan philosophical tradition that includes Hobbes, Spinoza and freethinking followers. Considered in these terms, Hume's Treatise constitutes the crowning achievement of the Radical Enlightenment. (shrink)

The Limits of Free Will presents influential articles by Paul Russell concerning free will and moral responsibility. The problems arising in this field of philosophy, which are deeply rooted in the history of the subject, are also intimately related to a wide range of other fields, such as law and criminology, moral psychology, theology, and, more recently, neuroscience. These articles were written and published over a period of three decades, although most have appeared in the past decade. Among the (...) topics covered: the challenge of skepticism; moral sentiment and moral capacity; necessity and the metaphysics of causation; practical reason; free will and art; fatalism and the limits of agency; moral luck, and our metaphysical attitudes of optimism and pessimism.

Free Will & The Tragic Predicament : Making Sense of Williams -/- The discussion in this paper aims to make better sense of free will and moral responsibility by way of making sense of Bernard Williams’ significant and substantial contribution to this subject. Williams’ fundamental objective is to vindicate moral responsibility by way of freeing it from the distortions and misrepresentations imposed on it by “the morality system”. What Williams rejects, in particular, are the efforts of “morality” to further “deepen” (...) or “refine” the notion of the voluntary, with a view to securing “ultimate justice”. It is these aims and aspirations, he argues, that take us to the precipice of scepticism. In Shame and Necessity (1993) Williams advances a vindicatory genealogy that unmasks the “illusions” and “fantasies” of our current ethical ideas as they relate to agency and responsibility. What we are then left with is the task of “recasting our ethical conceptions” . It is here that Williams is especially insistent on the importance and value of historical consciousness and reflection. The role of our reflections about the Greeks and tragedy is precisely to show that in order to move forward, into the future, we need to first look back at where we have come from. The value of these “untimely” observations is that they provide us with alternatives and options that we might otherwise lack. What we discover, when we consider the Greeks, is their commitment to a “pessimism of strength” that rests on rejecting scepticism. It is this two-sided perspective on our ethical predicament that delivers a more truthful account of our human situation, one that will help us discard those illusions and fantasies of "morality" that we are “better off” without. An account of this kind refuses to accept an optimism that insists that any form of responsible ethical life must be one that is immune to the influence of luck and fate. This is the fundamental lesson that we can learn from the ancient Greeks and that Williams seeks to “recover” for us. (shrink)

Knowledge implies the presence of a positive relation between a person and a fact. Factual ignorance, on the other hand, implies the absence of some positive relation between a person and a fact. The two most influential views of ignorance hold that what is lacking in cases of factual ignorance is knowledge or true belief, but these accounts fail to explain a number of basic facts about ignorance. In their place, we propose a novel and systematic defense of the view (...) that factual ignorance is the absence of awareness, an account that both comes apart from the dominant views and overcomes their deficiencies. Given the important role that ignorance plays in moral and legal theory and our understanding of various epistemic injustices, a precise and theoretically unproblematic account of the nature of ignorance is important not only for normative epistemology, but also for law, ethics, and applied epistemology.

This paper introduces constitutivism about practical reason, which is the view that we can justify certain normative claims by showing that agents become committed to these claims simply in virtue of acting. According to this view, action has a certain structural feature – a constitutive aim, principle, or standard – that both constitutes events as actions and generates a standard of assessment for action. We can use this standard of assessment to derive normative claims. In short, the authority of certain (...) normative claims arises from the bare fact that we are agents. This essay explains the constitutivst strategy, surveys the extant attempts to generate constitutivist theories, and considers the problems and prospects for the theory. (shrink)

[Significantly updated in Chapter 6 of Awareness and the Substructure of Knowledge] In order for a reason to justify an action or attitude it must be one that is possessed by an agent. Knowledge-centric views of possession ground our possession of reasons, at least partially, either in our knowledge of them or in our being in a position to know them. On virtually all accounts, knowing P is some kind of non-accidental true belief that P. This entails that knowing P (...) is a kind of non-accidental true representation that P. I outline a novel theory of the epistemic requirement on possession in terms of this more general state of non-accidental true representation. It is just as well placed to explain the motivations behind knowledge-centric views of possession, and it is also better placed to explain the extent of the reasons we possess in certain cases of deductive belief-updates and cases involving environmental luck. I conclude with three reflections. First, I indicate how my arguments generate a dilemma for Errol Lord’s view that possessing reasons is just a matter of being in a position to manifest one’s knowledge how to use them. Second, I explain how my view can simultaneously manage cases of environmental luck without falling prey to lottery cases. Finally, I sketch the direction for a further range of counterexamples to knowledge-centric theories of possession. (shrink)

ABSTRACTWhat conditions must be satisfied if a group is to count as having a justified belief? Jennifer Lackey has recently argued that any adequate account of group justification must be sensitive to both the evidence actually possessed by enough of a group's operative members as well as the evidence those members should have possessed. I first draw attention to a range of objections to Lackey's specific view of group justification and a range of concrete case intuitions any plausible view of (...) group justification must explain. I then offer an alternative view of group justification where the basic idea is that group justification is a matter of groups responsibly responding to their total evidence. This view both avoids the problems facing Lackey's account and also explains the relevant concrete case intuitions. (shrink)

The ancient Greeks almost universally accepted the thesis that virtues are skills. Skills have an underlying intellectual structure (logos), and having a particular skill entails understanding the relevant logos. possessing a general ability to diagnose and solve problems (phronesis). as well as having appropriate experience. Two implications of accepting this thesis for moral epistemology and epistemology in general are considered. Thinking of virtues as skills yields a viable virtue epistemology in which moral knowledge is a species of a general kind (...) of knowledge that is not philosophically suspect. Also, the debate between internalists and externalists in epistemology is subversively resolved as moot by adopting this strategy: the locus of justification for a belief is in the nature of skill. Thus, the contingent fact that some skills allow Homo Sapiens an ‘internal access’. while others do not, is theoretically neutral when considering the nature of justification per se. (shrink)

This paper develops a trivalent semantics for the truth conditions and the probability of the natural language indicative conditional. Our framework rests on trivalent truth conditions first proposed by Cooper (1968) and Belnap (1973) and it yields two logics of conditional reasoning: (i) a logic C of certainty-preserving inference; and (ii) a logic U for uncertain reasoning that preserves the probability of the premises. We show systematic correspondences between trivalent and probabilistic representations of inferences in either framework, and we use (...) the distinction between the two systems to cast light on the validity of inferences such as Modus Ponens, Or-To-If, and Conditional Excluded Middle. Specifically, the conditional behaves monotonically in C, but non-monotonically in U; Modus Ponens is valid in C, but valid in U only for non-nested conditionals. The result is a unified account of the semantics and epistemology of indicative conditionals that can be fruitfully applied to analyzing the validity of conditional inferences. (shrink)

In this book, Russell examines Hume's notion of free will and moral responsibility. It is widely held that Hume presents us with a classic statement of a compatibilist position--that freedom and responsibility can be reconciled with causation and, indeed, actually require it. Russell argues that this is a distortion of Hume's view, because it overlooks the crucial role of moral sentiment in Hume's picture of human nature. Hume was concerned to describe the regular mechanisms which generate moral sentiments such as (...) responsibility, and Russell argues that his conception of free will must be interprted within this naturalistic framework. He goes on to discuss Hume's views about the nature and character of moral sentiment; the extent to which we have control over our moral character; and the justification of punishment. Throughout, Russell argues that the naturalistic avenue of interpretation of Hume's thought, far from draining it of its contemporary interest and significance, reveals it to be of great relevance to the ongoing contemporary debate - particuarly in relation to the views of P.F. Strawson and his influential paper "Freedom and Resentment". (shrink)

Alongside existing research into the social, political and economic impacts of the Web, there is a need to study the Web from a cognitive and epistemic perspective. This is particularly so as new and emerging technologies alter the nature of our interactive engagements with the Web, transforming the extent to which our thoughts and actions are shaped by the online environment. Situated and ecological approaches to cognition are relevant to understanding the cognitive significance of the Web because of the emphasis (...) they place on forces and factors that reside at the level of agent–world interactions. In particular, by adopting a situated or ecological approach to cognition, we are able to assess the significance of the Web from the perspective of research into embodied, extended, embedded, social and collective cognition. The results of this analysis help to reshape the interdisciplinary configuration of Web Science, expanding its theoretical and empirical remit to include the disciplines of both cognitive science and the philosophy of mind.

[This papers explores a novel case for the normativity of knowledge for belief – something that is compatible with the knowledge/factual awareness distinction I've explored elsewhere.] There are two different kinds of enkratic principles for belief: evidential enkratic principles and normative enkratic principles. It’s frequently taken for granted that there’s not an important difference between them. But evidential enkratic principles are undermined by considerations that gain no traction at all against their normative counterparts. The idea that such an asymmetry exists (...) between evidential and normative enkratic principles is surprising all on its own. It is also something that calls out for explanation. Similarly, the considerations that undermine evidential enkratic principles also undermine certain narrow-scope evidential principles. This too generates explanatory questions. I show how a knowledge-first view of rationality can easily address these explanatory questions. Thus we have one more reason to put knowledge first in [some areas of] epistemology. (shrink)

Proponents of the extended mind have suggested that phenomenal transparency may be important to the way we evaluate putative cases of cognitive extension. In particular, it has been suggested that in order for a bio-external resource to count as part of the machinery of the mind, it must qualify as a form of transparent equipment or transparent technology. The present paper challenges this claim. It also challenges the idea that phenomenological properties can be used to settle disputes regarding the constitutional (...) status of bio-external resources in episodes of extended cognizing. Rather than regard phenomenal transparency as a criterion for cognitive extension, we suggest that transparency is a feature of situations that support the ascription of certain cognitive/mental dispositional properties to both ourselves and others. By directing attention to the forces and factors that motivate disposition ascriptions, we arrive at a clearer picture of the role of transparency in arguments for extended cognition and the extended mind. As it turns out, transparency is neither necessary nor sufficient for cognitive extension, but this does not mean that it is entirely irrelevant to our understanding of the circumstances in which episodes of extended cognizing are apt to arise.

The distinction between propositional and doxastic justification is the distinction between having justification to believe P (= propositional justification) versus having a justified belief in P (= doxastic justification). The focus of this paper is on doxastic justification and on what conditions are necessary for having it. In particular, I challenge the basing demand on doxastic justification, i.e., the idea that one can have a doxastically justified belief only if one’s belief is based on an epistemically appropriate reason. This demand (...) has been used to refute versions of coherentism and conservatism about perceptual justification as well as to defend phenomenal “conservatism” and other views besides. In what follows I argue that there is virtually no reason to think there is a basing demand on doxastic justification. I also argue that even if the basing demand were true, it would still fail to serve the dialectical purposes for which it has been employed in arguments concerning coherentism, conservatism, and phenomenal “conservatism”. I conclude by discussing the fact that knowledge has a basing demand and show why this needn’t raise the same sort of problems for coherentism and conservatism that doxastic justification’s basing demand seemed to.

Examples of extended cognition typically involve the use of technologically low-grade bio-external resources (e.g., the use of pen and paper to solve long multiplication problems). The present paper describes a putative case of extended cognizing based around a technologically advanced mixed reality device, namely, the Microsoft HoloLens. The case is evaluated from the standpoint of a mechanistic perspective. In particular, it is suggested that a combination of organismic (e.g., the human individual) and extra-organismic (e.g., the HoloLens) resources form part of (...) a common mechanism that realizes a bona fide cognitive routine. In addition to demonstrating how the theoretical resources of neo-mechanical philosophy might be used to evaluate extended cognitive systems, the present paper illustrates one of the ways in which mixed reality devices, virtual objects (i.e., holograms), and online (Internet-accessible) computational routines might be incorporated into human cognitive processes. This, it is suggested, speaks to the recent interest in mixed/virtual reality technologies across a number of disciplines. It also introduces us to issues that cross-cut disparate fields of philosophical research, such as the philosophy of science and the philosophy of technology. (shrink)

The standard analysis of supererogation is that of optional actions that are praiseworthy to perform, but not blameworthy to skip. Widespread assumptions are that action beyond the call is at least necessarily equivalent to supererogation ("The Equivalence") and that forgoing certain agent-favoring prerogatives entails supererogation (“The Corollary”). I argue that the classical conception of supererogation is not reconcilable with the Equivalence or the Corollary, and that the classical analysis of supererogation is seriously defective. I sketch an enriched conceptual scheme, “Doing (...) Well Enough (DWE)”, that allows for distinct analyses of action beyond the call and supererogation, among other often neglected fundamental moral notions. Parallels and asymmetries with suberogation are briefly explored. Apparently, DWE’s core act-evaluative notions are more fundamental than the agent-evaluative ones of supererogation/suberogation.

I provide a novel knowledge-first account of justification that avoids the pitfalls of existing accounts while preserving the underlying insight of knowledge-first epistemologies: that knowledge comes first. The view I propose is, roughly, this: justification is grounded in our practical knowledge (know-how) concerning the acquisition of propositional knowledge (knowledge-that). I first refine my thesis in response to immediate objections. In subsequent sections I explain the various ways in which this thesis is theoretically superior to existing knowledge-first accounts of justification. The (...) upshot is a virtue-theoretic, knowledge-first view of justification that is internalist-friendly and able to explain more facts about justification than any other available view. (shrink)

In the replies to my critics that follow I offer a more detailed account of the specific papers that they discuss or examine. The papers that they are especially concerned with are: “The Material World and Natural Religion in Hume’s Treatise” (Ryan) [Essay 3], “Hume’s Skepticism and the Problem of Atheism” (Fosl) [Essay 12], and “Hume’s Philosophy of Irreligion and the Myth of British Empiricism (Gautier) [Essay 16].

In their article ’Is Pregnancy a Disease? A Normative Approach’, Anna Smajdor and Joona Räsänen contend that, on several of the most prominent accounts of disease, pregnancy should be considered a disease. More specifically, of the five accounts they discuss, each renders pregnancy a disease or suffers serious conceptual problems otherwise. They take issue specifically with the dysfunction account of disease and argue that it suffers several theoretical difficulties. In this response, we focus on defending the dysfunction account against their (...) main objections and show why a version of the dysfunction account is viable on account of the indispensability of normativity in biology and medicine. After disarming their main objections to the dysfunction account, we briefly respond to their treatment of the normality of pregnancy and then draw a distinction between adverse symptoms and underlying causes to show why even though pregnancy may have ’disease-like’ features, it is not a disease.

This paper argues that, given a certain apparently inevitable thesis about content, we could not know our own minds. The thesis is that the content of a thought is determined by its relational properties.

Endurantists have recently faced a mereological puzzle in various forms. Here I argue that, instead of presenting a genuine worry, the puzzle actually reveals a common misunderstanding about the endurantist ontology. Furthermore, through this discussion of the alleged problem and the misunderstanding which motivates it, I reveal metaphysical commitments the endurantist has that may not be widely recognized. For instance, she is committed to interesting and perhaps controversial views about shape and location. I highlight these commitments and what they mean (...) for the endurantist. (shrink)

Recasting Hume and Early Modern Philosophy is a collection of essays that are all concerned with major figures and topics in the early modern philosophy. Most of the essays are concerned, more specifically, with the philosophy of David Hume (1711-1776). The sixteen essays included in this collection are divided into five parts. These parts are arranged under the headings of: (1) Metaphysics and Epistemology; (2) Free Will and Moral Luck; (3) Ethics, Virtue and Optimism; (4) Skepticism, Religion and Atheism; and (...) (5) Irreligion and the Unity of Hume’s Thought. A particularly important theme running through many of these essays is the subject of Hume’s irreligious aims and intentions. The fifth and final part of the collection is devoted to an articulation and defence of this specific understanding of Hume’s philosophical thought. (shrink)

Appears to give the first model-theoretic account of both "must" and "ought" (without conflating them with one another). Some key pre-theoretic semantic and pragmatic phenomena that support a negative answer to the main title question are identified and a conclusion of some significance is drawn: a pervasive bipartisan presupposition of twentieth century ethical theory and deontic logic is false. Next, an intuitive model-theoretic framework for "must" and "ought" is hypothesized. It is then shown how this hypothesis helps to explain and (...) predict all the pre-theoretic phenomena previously observed. Next, I show that the framework hypothesized possesses additional expressive and explanatory power (e.g. derivatively predicting the existence of supererogatory and permissibly suboptimal alternatives), thus adding further confirmation that it is on the right track.
