In the 1920s, David Hilbert proposed a research program with the aim of providing mathematics with a secure foundation. This was to be accomplished by first formalizing logic and mathematics in their entirety, and then showing---using only so-called finitistic principles---that these formalizations are free of contradictions. ;In the area of logic, the Hilbert school accomplished major advances both in introducing new systems of logic, and in developing central metalogical notions, such as completeness and decidability. The analysis of unpublished material presented (...) in Chapter 2 shows that a completeness proof for propositional logic was found by Hilbert and his assistant Paul Bernays already in 1917--18, and that Bernays's contribution was much greater than is commonly acknowledged. Aside from logic, the main technical contribution of Hilbert's Program are the development of formal mathematical theories and proof-theoretical investigations thereof, in particular, consistency proofs. In this respect Wilhelm Ackermann's 1924 dissertation is a milestone both in the development of the Program and in proof theory in general. Ackermann gives a consistency proof for a second-order version of primitive recursive arithmetic which, surprisingly, explicitly uses a finitistic version of transfinite induction up to www . He also gave a faulty consistency proof for a system of second-order arithmetic based on Hilbert's &egr;-substitution method. Detailed analyses of both proofs in Chapter 3 shed light on the development of finitism and proof theory in the 1920s as practiced in Hilbert's school. ;In a series of papers, Charles Parsons has attempted to map out a notion of mathematical intuition which he also brings to bear on Hilbert's finitism. According to him, mathematical intuition fails to be able to underwrite the kind of intuitive knowledge Hilbert thought was attainable by the finitist. It is argued in Chapter 4 that the extent of finitistic knowledge which intuition can provide is broader than Parsons supposes. According to another influential analysis of finitism due to W. W. Tait, finitist reasoning coincides with primitive recursive reasoning. The acceptance of non-primitive recursive methods in Ackermann's dissertation presented in Chapter 3, together with additional textual evidence presented in Chapter 4, shows that this identification is untenable as far as Hilbert's conception of finitism is concerned. Tait's conception, however, differs from Hilbert's in important respects, yet it is also open to criticisms leading to the conclusion that finitism encompasses more than just primitive recursive reasoning.

What is the correct metric of distributive justice? Proponents of the capability approach claim that distributive metrics should be articulated in terms of individuals’ effective abilities to achieve important and worthwhile goals. Defenders of resourcism, by contrast, maintain that metrics should instead focus on the distribution of external resources. This debate is now more than three decades old, and it has produced a vast and still growing literature. The present paper aims to provide a fresh perspective on this protracted debate. (...) It does so by defending capability metrics while also criticizing the two most common arguments used to support them, and sympathetically reconstructing the arguments for resourcism. I ultimately argue that while sweeping defenses of the capability approach do not succeed, capability theorists can indeed vindicate the justice-relevance of certain capabilities while still accommodating what is plausible in resourcism.

This paper argues that societal duties of health promotion are underwritten (at least in large part) by a principle of beneficence. Further, this principle generates duties of justice that correlate with rights, not merely “imperfect” duties of charity or generosity. To support this argument, I draw on a useful distinction from bioethics and on a somewhat neglected approach to social obligation from political philosophy. The distinction is that between general and specific beneficence; and the approach from political philosophy has at (...) times been called equality of concern. After clarifying the distinction and setting out the basis of the equality of concern view, I argue that the result is a justice-based principle of “specific” beneficence that should be reflected in a society’s health policy. I then draw on this account to criticize, refine, and extend some prominent health care policy proposals from the bioethics literature. (shrink)

The ideas behind open source software are currently applied to the production of encyclopedias. A sample of six English text-based, neutral-point-of-view, online encyclopedias of the kind are identified: h2g2, Wikipedia, Scholarpedia, Encyclopedia of Earth, Citizendium and Knol. How do these projects deal with the problem of trusting their participants to behave as competent and loyal encyclopedists? Editorial policies for soliciting and processing content are shown to range from high discretion to low discretion; that is, from granting unlimited trust to limited (...) trust. Their conceptions of the proper role for experts are also explored and it is argued that to a great extent they determine editorial policies. Subsequently, internal discussions about quality guarantee at Wikipedia are rendered. All indications are that review and ?super-review? of new edits will become policy, to be performed by Wikipedians with a better reputation. Finally, while for encyclopedias the issue of organizational trust largely coincides with epistemological trust, a link is made with theories about the acceptance of testimony. It is argued that both non-reductionist views (the ?acceptance principle? and the ?assurance view?) and reductionist ones (an appeal to background conditions, and a?newly defined??expertise view?) have been implemented in editorial strategies over the past decade.

Many virtual communities that rely on user-generated content (such as social news sites, citizen journals, and encyclopedias in particular) offer unrestricted and immediate ‘write access’ to every contributor. It is argued that these communities do not just assume that the trust granted by that policy is well-placed; they have developed extensive mechanisms that underpin the trust involved (‘backgrounding’). These target contributors (stipulating legal terms of use and developing etiquette, both underscored by sanctions) as well as the contents contributed by them (...) (patrolling for illegal and/or vandalist content, variously performed by humans and bots; voting schemes). Backgrounding trust is argued to be important since it facilitates the avoidance of bureaucratic measures that may easily cause unrest among community members and chase them away. (shrink)

Aquinas’s actual response to a naturalistic challenge at ST I.2.3 is one which most naturalists would find unimpressive. However, I shall argue that there is a stronger response latent in his philosophical system. I take Quine as an example of a methodological naturalist, examine the roots of his position and look at two critical responses to his views (those of BonJour and Boghossian). If one adjusts some of the problematical aspects of their responses and establishes a hybrid position on the (...) epistemology and metaphysics of an antinaturalistic stance, it turns out to be the position Aquinas himself takes on meaning and knowledge.

Darcy's law is a phenomenological relationship for fluid flow rate that finds one of its principle applications in hydrology. Theoretical hydrologists rely upon a multiplicity of conceptual models to carry out approximate derivations of Darcy's law. These derivations provide structural explanations of the law; they require the application of fundamental principles, such as conservation of momentum, to idealized models of the porous media within which the flow occurs. In practice, recognition of the idealized conditions incorporated into models facilitates the empirical (...) clarification of the domain within which the law remains accurate. Structural explanations also contribute to the physical interpretation of phenomenological parameters. (shrink)

Cognitive organisms have three rather different techniques for intelligently regulating their intake of environmental information. In order of the time needed to uncover information they are: 1. control of attention: within an image produced by a given sensor certain elements can be selected for additional processing; 2. control of gaze: the orientation and resolution (center of foveation) of the sensor can be regulated to create a new image; 3. control of activity: certain non-perceptual actions can be performed to increase the (...) probability of unearthing salient information that currently is unavailable, hard to detect, or hard to compute.

In this paper we briefly examine and evaluate Quine’s physicalism. On the supposition, in accordance with Quine’s views, that there can be no change of any sort without a physical change, we argue that this point leaves plenty of room to understand and accept a limited autonomy of the special sciences and of other domains of disciplinary and common-sense inquiry and discourse. The argument depends on distinguishing specific, detailed programs of reduction from the general Quinean strategy of reduction by explication. (...) We argue that the details of the relations of particular sciences, disciplines and domains of discourse depend on empirical evidence and empirical-theoretical developments and that the generalized approach of reduction by explication is also subject to related empirical-theoretical constraints. So understood, physicalism lacks much of the controversial force and many of the implications sometimes associated with it. (shrink)

During the two last decades, speeded up by the development of the Internet, several types of commons have been opened up for intellectual resources. In this article their variety is being explored as to the kind of resources and the type of regulation involved. The open source software movement initiated the phenomenon, by creating a copyright-based commons of source code that can be labelled `dynamic': allowing both use and modification of resources. Additionally, such a commons may be either protected from (...) appropriation (by `copyleft' licensing), or unprotected. Around the year 2000, this approach was generalized by the Creative Commons initiative. In the process they added a `static' commons, in which only use of resources is allowed. This mould was applied to the sciences and the humanities in particular, and various Open Access initiatives unfolded. A final aspect of copyright-based commons is the distinction between active and passive commons: while the latter is only a site for obtaining resources, the former is also a site for production of new resources by communities of volunteers (`peer production'). Finally, several patent commons are discussed, which mainly aim at preventing patents blocking the further development of science. Throughout, attention is drawn to interrelationships between the various commons. (shrink)

A critique of two eliminative positions in philosophy of mind in the light of Michael Polanyi's account of mind: Rorty's disappearance theory and Churchland's eliminative materialism.

Huang-Lao is now generally regarded as a set of ideas that gained currency from the final stages of the Warring States period to well into the Han dynasty. "Huang" stands for Huangdi, the Yellow Emperor; "Lao" refers to Laozi, the "Old Master," who is traditionally regarded as the founder of Daoism. Huang-Lao is thus a combination of ideas attributed to the mythical figures of the Yellow Emperor and Laozi. What those ideas are and how they have manifested themselves in Chinese (...) history remains the subject of heated debate. (shrink)

Masculinity? This book attempts to answer this one-word question by revisiting key philosophical concepts in the construction of masculinity, not in order to re-write or debunk them again, but in order to provide a radically new departure to what masculinity means today. This new departure focuses on an understanding of sexuality and gender that is neither structured in oppositional terms nor in performative terms, but in a perpendicular relation akin to that which brings space and time together. In doing so, (...) this book doesn’t aim to establish yet another theory within the field of masculism or men’s studies, but to put forward a personal account of how a revised understanding of the relationship between space, time, and gender can thoroughly alter concepts of masculinity. virility and patriarchy.

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)

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)

Proponents of public reason views hold that the exercise of political power ought to be acceptable to all reasonable citizens. This article elucidates the common structure shared by all public reason views, first by identifying a set of questions that all such views must answer and, second, by showing that the answers to these questions stand in a particular relationship to each other. In particular, we show that what we call the ‘rationale question’ is fundamental. This fact, and the common (...) structure more generally, are often overlooked or distorted within the literature. As a result, we argue, several prominent argumentative moves made by both critics and defenders of public reason are unsuccessful. Our overall conclusion is that discussions of public reason views would be more fruitful if they made consistent use of the common structure we identify. (shrink)

Public shaming plays an important role in upholding valuable social norms. But, under what conditions, if any, is it morally justifiable? Our aim in this paper is systemically to investigate the morality of public shaming, so as to provide an answer to this neglected question. We develop an overarching framework for assessing the justifiability of this practice, which shows that, while shaming can sometimes be morally justifiable, it very often is not. In turn, our framework highlights several reasons to be (...) concerned about the increasingly widespread phenomenon of online public shaming. (shrink)

For almost half a century, the person most responsible for fomenting brouhahas regarding degrees of plasticity in the writing of histories has been Hayden White. Yet, despite the voluminous responses provoked by White’s work, almost no effort has been made to treat White’s writings in a systematic yet sympathetic way as a philosophy of history. Herman Paul’s book begins to remedy that lack and does so in a carefully considered and extremely scholarly fashion. In his relatively brief six chapters (...) (plus an introduction), Paul packs a wealth of information. He convincingly demonstrates that a guiding theme of White’s work from earliest times has been that historians have no choice but to impose a structure on historical data and thus bear responsibility for structures so imposed. As such, a key philosophical question concerns on what bases White contends that a freedom of choice exists regarding forms given to recorded histories. This essay focuses on how Paul argues for a unified vision that answers this question, as well as how he offers an original and comprehensive conception of White’s writings. (shrink)

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.

In the 6th century, Paul the Persian used his own pen to write a summary of Aristotle's Peri Hermeneias in the Persian language. Severus Sebokht translated it into Syriac.

[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)

We are witnessing increasing use of the Internet, particular social media, to criticize (perceived or actual) moral failings and misdemeanors. This phenomenon of so-called ‘online public shaming’ could provide a powerful tool for reinforcing valuable social norms. But it also threatens unwarranted and severe punishments meted out by online mobs. This paper analyses the dangers associated with the informal enforcement of norms, drawing on Locke, but also highlights its promise, drawing on recent discussions of social norms. We then consider two (...) crucial conditions that online public shaming must meet in order to be justifiable: proportionality and accountability. We argue that these requirements are in fact frequently violated, rendering most cases of online public shaming unjustified. While the use of online public shaming against others’ vices has some apparent virtues, it is currently rarely justified, given its own vices. (shrink)

This paper explores the question: What would conceptual engineering have to be in order to promote social justice? Specifically, it argues that to promote social justice, conceptual engineering must deliver the following: it needs to be possible to deliberately implement a conceptual engineering proposal in large communities; it needs to be possible for a conceptual engineering proposal to bring about change to extant social categories; it needs to be possible to bring a population to adopt a conceptual engineering proposal for (...) the right reasons; and it needs to be possible to do – without producing harmful consequences. I show that, of the three dominant approaches to conceptual engineering in the literature, only one of them seems amenable to the idea that it is possible and legitimate to promote social justice in accordance with –.

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)

Social robots are robots that can interact socially with humans. As social robots and the artificial intelligence that powers them becomes more advanced, they will likely take on more social and work roles. This has many important ethical implications. In this paper, we focus on one of the most central of these, the impacts that social robots can have on human autonomy. We argue that, due to their physical presence and social capacities, there is a strong potential for social robots (...) to enhance human autonomy as well as several ways they can inhibit and disrespect it. We argue that social robots could improve human autonomy by helping us to achieve more valuable ends, make more authentic choices, and improve our autonomy competencies. We also argue that social robots have the potential to harm human autonomy by instead leading us to achieve fewer valuable ends ourselves, make less authentic choices, decrease our autonomy competencies, make our autonomy more vulnerable, and disrespect our autonomy. Whether the impacts of social robots on human autonomy are positive or negative overall will depend on the design, regulation, and use we make of social robots in the future. (shrink)

In this paper, I explain the kinematics of non-ideal metalinguistic disagreement. This occurs when one speaker has greater control in the joint activity of pairing contents with words in a context. I argue that some forms of non-ideal metalinguistic disagreement are deeply worrying, namely those that involves certain power imbalances. In such cases, a speaker possesses illegitimate control in metalinguistic disagreement owing to the operation of identity prejudice. I call this metalinguistic injustice. The wrong involves restricting a speaker from participating (...) in the processes that determine the epistemic/linguistic resources of a conversation, and/or undermining a speaker's ability to affect metalinguistic outcomes.

As robots and Artificial Intelligences become more enmeshed in rich social contexts, it seems inevitable that we will have to make them into moral machines equipped with moral skills. Apart from the technical difficulties of how we could achieve this goal, we can also ask the ethical question of whether we should seek to create such Artificial Moral Agents (AMAs). Recently, several papers have argued that we have strong reasons not to develop AMAs. In response, we develop a comprehensive analysis (...) of the relevant arguments for and against creating AMAs, and we argue that all things considered we have strong reasons to continue to responsibly develop AMAs. The key contributions of this paper are threefold. First, to provide the first comprehensive response to the important arguments made against AMAs by Wynsberghe and Robbins (in “Critiquing the Reasons for Making Artificial Moral Agents”, Science and Engineering Ethics 25, 2019) and to introduce several novel lines of argument in the process. Second, to collate and thematise for the first time the key arguments for and against AMAs in a single paper. Third, to recast the debate away from blanket arguments for or against AMAs in general, to a more nuanced discussion about the use of what sort of AMAs, in what sort of contexts, and for what sort of purposes is morally appropriate.

Opponents of the computational theory of mind have held that the theory is devoid of explanatory content, since whatever computational procedures are said to account for our cognitive attributes will also be realized by a host of other ‘deviant’ physical systems, such as buckets of water and possibly even stones. Such ‘triviality’ claims rely on a simple mapping account of physical implementation. Hence defenders of CTM traditionally attempt to block the trivialization critique by advocating additional constraints on the implementation relation. (...) However, instead of attempting to ‘save’ CTM by constraining the account of physical implementation, I argue that the general form of the triviality argument is invalid. I provide a counterexample scenario, and show that SMA is in fact consistent with empirically rich and theoretically plausible versions of CTM. This move requires rejection of the computational sufficiency thesis, which I argue is scientifically unjustified in any case. By shifting the ‘burden of explanatory force’ away from the concept of physical implementation, and instead placing it on salient aspects of the target phenomenon to be explained, it’s possible to retain a maximally liberal and unfettered view of physical implementation, and at the same time defuse the triviality arguments that have motivated defenders of CTM to impose various theory-laden constraints on SMA.

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)

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)

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.

This is a contribution to a Book symposium on The Limits of Free Will: Selected Essays by Paul Russell. Russell provides replies to three critics of The Limits of Free Will. The first reply is to Robert Wallace and focuses on the question of whether there is a conflict between the core compatibilist and pessimist components of the "critical compatibilist" position that Russell has advanced. The second reply is to Angela Smith's discussion of the "narrow" interpretation of moral responsibility (...) responsibility (as defended by R. Jay Wallace) and how best to respond to it. The third and last reply is concerned with Christopher Bennett's criticism of Russell's views concerning "motivational scepticism" and the possibility of pure practical reasons. (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)

[Significantly updated in Chapter 7 of Awareness and the Substructure of Knowledge] Many have found it plausible that knowledge is a constitutively normative state, i.e. a state that is grounded in the possession of reasons. Many have also found it plausible that certain cases of proprioceptive knowledge, memorial knowledge, and self-evident knowledge are cases of knowledge that are not grounded in the possession of reasons. I refer to these as cases of basic knowledge. The existence of basic knowledge forms a (...) primary objection to the idea that knowledge is a constitutively normative state. In what follows I offer a way through the apparent dilemma of having to choose between either basic knowledge or the normativity of knowledge. The solution involves homing in on a state of awareness (≈non-accidental true representation) that is distinct from knowledge and which in turn grounds the normativity of knowledge in a way that is fully consistent with the existence of basic knowledge. An upshot of this is that externalist theories of knowledge turn out to be fully compatible with the thesis that knowledgeable beliefs are always beliefs that are justified by the reasons one possesses.

People more frequently select norm-violating factors, relative to norm- conforming ones, as the cause of some outcome. Until recently, this abnormal-selection effect has been studied using retrospective vignette-based paradigms. We use a novel set of video stimuli to investigate this effect for prospective causal judgments—i.e., judgments about the cause of some future outcome. Four experiments show that people more frequently select norm- violating factors, relative to norm-conforming ones, as the cause of some future outcome. We show that the abnormal-selection effects (...) are not primarily explained by the perception of agency (Experiment 4). We discuss these results in relation to recent efforts to model causal judgment. (shrink)

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

Public reason views hold that the exercise of political power must be acceptable to all reasonable citizens. A growing number of philosophers argue that this reasonable acceptability principle (RAP) can be justified by appealing to the value of civic friendship. They claim that a valuable form of political community can only be achieved among the citizens of pluralistic societies if they refrain from appealing to controversial ideals and values when justifying the exercise of political power to one another. This paper (...) argues against such accounts. In order to justify RAP, one must explain and defend a conception of reasonableness. Civic friendship is unfit to perform this task, rendering it unable to ground public reason alone. Meanwhile, pluralist views that combine civic friendship with other considerations in order to specify RAP either fail or make civic friendship a spare wheel in the argument for public reason.

Many of our most important goals require months or even years of effort to achieve, and some never get achieved at all. As social psychologists have lately emphasized, success in pursuing such goals requires the capacity for perseverance, or "grit." Philosophers have had little to say about grit, however, insofar as it differs from more familiar notions of willpower or continence. This leaves us ill-equipped to assess the social and moral implications of promoting grit. We propose that grit has an (...) important epistemic component, in that failures of perseverance are often caused by a significant loss of confidence that one will succeed if one continues to try. Correspondingly, successful exercises of grit often involve a kind of epistemic resilience in the face of failure, injury, rejection, and other setbacks that constitute genuine evidence that success is not forthcoming. Given this, we discuss whether and to what extent displays of grit can be epistemically as well as practically rational. We conclude that they can be (although many are not), and that the rationality of grit will depend partly on features of the context the agent normally finds herself in. In particular, grit-friendly norms of deliberation might be irrational to use in contexts of severe material scarcity or oppression. (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.

[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)

This paper explicates Descartes’ theory of intuition (intuitus). Departing from certain commentators, I argue that intuition, for Descartes, is a form of clear and distinct intellectual perception. Because it is clear and distinct, it is indubitable, infallible, and provides a grade of certain knowledge he calls ‘cognitio’. I pay special attention to why he treats intuition as a form of perception, and what he means when he says it is ‘clear and distinct’. Finally, I situate his view in relation to (...) those of his Scholastic predecessors on one hand and current theories on the other. His view anticipates the contemporary ‘perceptual model of intuition’, though it is much bolder with its promise of certainty. (shrink)

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.

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.

Creativity pervades human life. It is the mark of individuality, the vehicle of self-expression, and the engine of progress in every human endeavor. It also raises a wealth of neglected and yet evocative philosophical questions: What is the role of consciousness in the creative process? How does the audience for a work for art influence its creation? How can creativity emerge through childhood pretending? Do great works of literature give us insight into human nature? Can a computer program really be (...) creative? How do we define creativity in the first place? Is it a virtue? What is the difference between creativity in science and art? Can creativity be taught? The new essays that comprise The Philosophy of Creativity take up these and other key questions and, in doing so, illustrate the value of interdisciplinary exchange. Written by leading philosophers and psychologists involved in studying creativity, the essays integrate philosophical insights with empirical research. CONTENTS I.
