– We offer a new motivation for imprecise probabilities. We argue that there are propositions to which precise probability cannot be assigned, but to which imprecise probability can be assigned. In such cases the alternative to imprecise probability is not precise probability, but no probability at all. And an imprecise probability is substantially better than no probability at all. Our argument is based on the mathematical phenomenon of non-measurable sets. Non-measurable propositions cannot receive precise probabilities, but there is a natural (...) way for them to receive imprecise probabilities. The mathematics of non-measurable sets is arcane, but its epistemological import is far-reaching; even apparently mundane propositions are liable to be affected by non-measurability. The phenomenon of non-measurability dramatically reshapes the dialectic between critics and proponents of imprecise credence. Non-measurability offers natural rejoinders to prominent critics of imprecise credence. Non-measurability even reverses some of the critics’ arguments—by the very lights that have been used to argue against imprecise credences, imprecise credences are better than precise credences.

The answer to the fine-tuning problem of the universe has been traditionally sought in terms of either design or multiverse. In philosophy circles, this is sometimes expanded by adding the option of explanatory nihilism—the claim that there is no explanation for statements of that high level of generality: fine-tunings are brute facts. In this paper, we consider the fourth option which, at least in principle, is available to us: co-evolution of the universe and observers. Although conceptual roots of this approach (...) could be found already in ancient stoicism, it is still the least investigated explanatory option for resolving the problem of empirical fine tunings. We offer two preliminary models along which the co-evolution hypothesis could be developed further. They are still on the level of speculative metaphysics, but there are opportunities along the way to generate predictions which are in principle testable, especially in the domain of large-scale numerical simulations.

This paper introduces and defends the paradigm response to external world skepticism. To understand it, consider an analogy. One of the hallmarks of being a bird is an ability to fly. A penguin lacks this hallmark and thus fails to be a paradigm bird. Likewise, there are various hallmarks of knowledge. Some of your external world beliefs lack some of these hallmarks, and thus fail to be paradigm cases of knowledge. Just as the inability of penguins to fly doesn’t prevent (...) them from being birds, likewise the lack of these hallmarks doesn’t prevent your beliefs from being knowledge. It just prevents them from being paradigm cases thereof. (shrink)

_ Source: _Page Count 17 Michael Huemer, Ernest Sosa, and Jonathan Vogel have offered a critique of the sensitivity condition on knowledge. According to them, the condition implies that you cannot know of any particular proposition that you do not falsely believe it. Their arguments rest on the claim that you cannot sensitively believe of any particular proposition that you do not falsely believe it. However, as we shall see, these philosophers are mistaken. You can do so. That said, these (...) philosophers were close to the mark. There are some related propositions that you cannot believe sensitively. These propositions are interesting in another respect: they can be used to construct a new skeptical argument that is superior in some respects to a more traditional skeptical argument. This new skeptical argument also reveals insights about the relationship between internalism, externalism, and skepticism. (shrink)

I want to combine two hitherto largely independent research projects, scientific understanding and mechanistic explanations. Understanding is not only achieved by answering why-questions, that is, by providing scientific explanations, but also by answering what-questions, that is, by providing what I call scientific descriptions. Based on this distinction, I develop three forms of understanding: understanding-what, understanding-why, and understanding-how. I argue that understanding-how is a particularly deep form of understanding, because it is based on mechanistic explanations, which answer why something happens in (...) virtue of what it is made of. I apply the three forms of understanding to two case studies: first, to the historical development of thermodynamics and, second, to the differences between the Clausius and the Boltzmann entropy in explaining thermodynamic processes.

This note is a sequel to Huber. It is shown that obeying a normative principle relating counterfactual conditionals and conditional beliefs, viz. the royal rule, is a necessary and sufficient means to attaining a cognitive end that relates true beliefs in purely factual, non-modal propositions and true beliefs in purely modal propositions. Along the way I will sketch my idealism about alethic or metaphysical modality.

Does communicative retributivism necessarily negate capital punishment? My answer is no. I argue that there is a place, though a very limited and unsettled one, for capital punishment within the theoretical vision of communicative retributivism. The death penalty, when reserved for extravagantly evil murderers for the most heinous crimes, is justifiable by communicative retributive ideals. I argue that punishment as censure is a response to the preceding message sent by the offender through his criminal act. The gravity of punishment should (...) be commensurate to the preceding criminal message, so that the offender can face up to the nature and significance of his crime. All murders are not the same. To measure up to the most evil and humanity-degrading murderous message, capital punishment should be the counter-message. Next, I argue that capital punishment does not necessarily violate human dignity. The death penalty and torture may both disrupt human dignity, yet in distinct ways. The death penalty terminates life, the vessel that holds together autonomy, while torture directly assaults autonomy. Torture is never permissible as a form of punishment. But death penalty, when used only on the extravagant evildoers, is justifiable, as life is thoroughly degraded by his own evil act. Further, I argue that mercy is integral to communicative retributivists’ theory of capital punishment. (shrink)

When people argue, they are vulnerable to unwanted and costly changes in their beliefs. This vulnerability motivates the position that belief involuntarism makes argument inherently adversarial, as well as the development of alternatives to adversarial argumentation such as “invitational rhetoric”. The emphasis on involuntary belief change in such accounts, in our perspective, neglects three dimensions of arguing: the diversity of arguer intentions, audience agency, and the benefits of belief change. The complex impact of arguments on both audiences and arguers involves (...) vulnerabilities related to various forces of argument, not just the intellectual force of premise-conclusion complexes. Shifting emphasis from adversariality to vulnerability, we propose a more holistic understanding of argument, in which vulnerability reveals various sources of strength and opportunity in addition to risk.

There is a line of reasoning in metaepistemology that is congenial to naturalism and hard to resist, yet ultimately misguided: that knowledge might be a natural kind, and that this would undermine the use of conceptual analysis in the theory of knowledge. In this paper, I first bring out various problems with Hilary Kornblith’s argument from the causal–explanatory indispensability of knowledge to the natural kindhood of knowledge. I then criticize the argument from the natural kindhood of knowledge against the method (...) of conceptual analysis in the theory of knowledge. A natural motivation for this argument is the following seemingly plausible principle: if knowledge is a natural kind, then the concept of knowledge is a natural kind concept. Since this principle lacks adequate support, the crucial semantic claim that the concept of knowledge is a natural kind concept must be defended in some more direct way. However, there are two striking epistemic disanalogies between the concept of knowledge and paradigmatic natural kind concepts that militate against this semantic claim. Conceptual analyses of knowledge are not affected by total error, and the proponents of such analyses are not subject to a priori conceptual obliviousness. I conclude that the argument from natural kindhood does not succeed in undermining the use of conceptual analysis in the theory of knowledge. (shrink)

Epistemic closure has been a central issue in epistemology over the last forty years. According to versions of the relevant alternatives and subjunctivist theories of knowledge, epistemic closure can fail: an agent who knows some propositions can fail to know a logical consequence of those propositions, even if the agent explicitly believes the consequence (having “competently deduced” it from the known propositions). In this sense, the claim that epistemic closure can fail must be distinguished from the fact that agents do (...) not always believe, let alone know, the consequences of what they know—a fact that raises the “problem of logical omniscience” that has been central in epistemic logic. This paper, part I of II, is a study of epistemic closure from the perspective of epistemic logic. First, I introduce models for epistemic logic, based on Lewis’s models for counterfactuals, that correspond closely to the pictures of the relevant alternatives and subjunctivist theories of knowledge in epistemology. Second, I give an exact characterization of the closure properties of knowledge according to these theories, as formalized. Finally, I consider the relation between closure and higher-order knowledge. The philosophical repercussions of these results and results from part II, which prompt a reassessment of the issue of closure in epistemology, are discussed further in companion papers. As a contribution to modal logic, this paper demonstrates an alternative approach to proving modal completeness theorems, without the standard canonical model construction. By “modal decomposition” I obtain completeness and other results for two non-normal modal logics with respect to new semantics. One of these logics, dubbed the logic of ranked relevant alternatives, appears not to have been previously identified in the modal logic literature. More broadly, the paper presents epistemology as a rich area for logical study. (shrink)

There is some consensus that for S to know that p, it cannot be merely a matter of luck that S’s belief that p is true. This consideration has led Duncan Pritchard and others to propose a safety condition on knowledge. In this paper, we argue that the safety condition is not a proper formulation of the intuition that knowledge excludes luck. We suggest an alternative proposal in the same spirit as safety, and find it lacking as well.

Taking his conceptual cue from Ernest Sosa, John Turri has offered a putative conceptual solution to the Gettier problem: Knowledge is cognitively adept belief, and no Gettiered belief is cognitively adept. At the core of such adeptness is a relation of manifestation. Yet to require that relation within knowing is to reach for what amounts to an infallibilist conception of knowledge. And this clashes with the spirit behind the fallibilism articulated by Gettier when stating his challenge. So, Turri’s form of (...) response is irrelevant to that challenge, which was intended to pose a conceptual problem within fallibilist conceptions of knowledge. (And that failure on Turri’s part needs to be highlighted to remind epistemologists of the need to assess Gettier cases by a fallibilist standard. Although that need was described earlier by Robert Almeder, apparently his advice is being overlooked. This paper develops it anew, in a more general form.). (shrink)

This paper undermines a paradigmatic form of sceptical reasoning. It does this by describing, and then dialectically dissolving, the sceptical-independence presumption, upon which that form of sceptical reasoning relies.

We may usefully distinguish between one’s having fallible knowledge and having a fallibilist stance on some of one’s knowledge. A fallibilist stance could include a concessive knowledge-attribution. But it might also include a questioning knowledge-attribution. Attending to the idea of a QKA leads to a distinction between what we may call closed knowledge that p and open knowledge that p. All of this moves us beyond Elgin’s classic tale of the epistemic capacities of Holmes and of Watson, and towards a (...) way of resolving Kripke’s puzzle about dogmatism and knowing. (shrink)

ABSTRACT: There are some problems with Lynne Baker’s constitution account of personal identity that become evident when we consider brain transplant thought experiments and two kinds of rare cases of conjoined twins — the first appears to be one organism but two persons and the second seems to involve two organisms associated with one person. To handle the problems arising from brain transplants, the constitution theorist must admit an additional level of constitution between the organism and the person. To resolve (...) the problems posed by the two kinds of conjoined twins, the constitution theorist must accept that constitution is not always a one-to-one relationship. RESUME: La théorie constitutionnelle de l’identité personnelle de Lynne Baker soulève certains problèmes qui deviennent évidents lorsque l’on considère des expériences de pensée sur des transplantations de cerveaux et deux genres de cas rares de jumeaux conjoints — du premier cas paraît s’ensuivre qu’il y a deux personnes pour un seul organisme alors que du deuxième découle qu’une seule personne existe dans deux organismes. Afin d’expliquer les problèmes qui surviennent avec les transplantations de cerveaux, le théoricien de la constitution doit admettre un niveau de constitution intermédiaire entre l’organisme et la personne. Pour résoudre les problèmes que posent les cas de jumeaux conjoints, le théoricien de la constitution doit accepter que la relation de constitution ne se réalise pas toujours entre deux termes.

Human subjects seem to have a type of introspective access to their mental states that allows them to immediately judge the types and intensities of their occurrent emotions, as well as what those emotions are about or “directed at”. Such judgments manifest what I call “emotion-direction beliefs”, which, if reliably produced, may constitute emotion-direction knowledge. Many psychologists have argued that the “directed emotions” such beliefs represent have a componential structure, one that includes feelings of emotional responses and related but independent (...) representations of what those feelings are about. I argue that such componentiality may help to explain how emotion-direction knowledge is achievable. I begin by developing a hybrid view of introspection that combines David Chalmers’ phenomenal realism with Alvin Goldman’s “partial redeployment” account of meta-belief content. I then provide a process-reliabilist account of introspectively gained emotion-direction knowledge that outlines the minimum conditions of reliably forming emotion-direction beliefs, and specifies several ways in which the warrant of such beliefs could be defeated by relevant counterfactual alternatives. The overall account suggests how distinct introspective processes might be epistemically synergistic. (shrink)

Edmund Gettier’s paper “Is Justified True Belief Knowledge?” first appeared in an issue of Analysis , dated June of 1963, and although it’s tempting to wax hyperbolic when discussing the paper’s importance and influence, it is fair to say that its impact on contemporary philosophy has been substantial and wide-ranging. Epistemology has benefited from 50 years of sincere and rigorous discussion of issues arising from the paper, and Gettier’s conclusion that knowledge is not justified true belief is sometimes offered as (...) an example of the reality of philosophical progress. However, what can be called the Gettier problem has little to do with the text of the famous paper itself. The importance of the Gettier problem does not depend on the attribution of the tripartite theory of knowledge to Plato, Chisholm, and Ayer, nor on the psychological plausibility of the par ..

This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic (...) theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can, though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence” some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology of persistence—are revealed.

In mathematics, any form of probabilistic proof obtained through the application of a probabilistic method is not considered as a legitimate way of gaining mathematical knowledge. In a series of papers, Don Fallis has defended the thesis that there are no epistemic reasons justifying mathematicians’ rejection of probabilistic proofs. This paper identifies such an epistemic reason. More specifically, it is argued here that if one adopts a conception of mathematical knowledge in which an epistemic subject can know a mathematical proposition (...) based solely on a probabilistic proof, one is then forced to admit that such an epistemic subject can know several lottery propositions based solely on probabilistic evidence. Insofar as knowledge of lottery propositions on the basis of probabilistic evidence alone is denied by the vast majority of epistemologists, it is concluded that this constitutes an epistemic reason for rejecting probabilistic proofs as a means of acquiring mathematical knowledge.

The indexical word “I” has traditionally been assumed to be an overt analogue to the concept of self, and the best model for understanding it. This approach, I argue, overlooks the essential role of cognitive phenomenology in the mastery of the concept of self. I suggest that a better model is to be found in a different kind of representation: phenomenal concepts or more generally phenomenally grounded concepts. I start with what I take to be the defining feature of the (...) concept of self, namely its “super-reflexivity”: to use this concept is not just to think of oneself, but to think of oneself as the thinker of the present thought. I call this familiar observation the “Thinker Intuition”. I review some shortcomings of the indexical model of the concept of self, which is the classical account of the Thinker Intuition. I go on to propose a different account, the “phenomenal model”, according to which the concept of self is a phenomenally grounded concept, anchored in a generic kind of cognitive phenomenolog...

Descartes’s Evil Demon argument has been the subject of many reconstructions in recent analytic debates. Some have proposed a reconstruction with a principle of Infallibility, others with a principle of Closure of Knowledge, others with more original principles. In this paper, I propose a new reconstruction, which relies on the combination of two principles, namely the Meta-Coherence principle and the principle of Closure of Justification. I argue that the argument construed in this way is the best interpretation of what is (...) really at play in the Evil Demon intuition, and also that this argument is dialectically much stronger than previous reconstructions. If this is right, then the “Closure plus Meta-Coherence” argument is what anti-sceptics should really be attacking. (shrink)

This paper characterizes various responses to the question, 'Why does our universe exist?' Some responses- that the question is senseless, that the existence of our universe is logically necessary- are implausible. Adjudication between more plausible responses requires us to evaluate the argument from the 'fine-tuning' of the universe, a refurbished version of the argument from design that appeals to cosmology rather than biology. The evidence of fine-tuning should lead us to adopt, albeit provisionally, cosmological fecundity, the hypothesis that there exist (...) many universes of varying characters. The existence of our universe is thereby rendered less surprising. This is to be preferred both to the theistic hypothesis and to the view that the existence of our universe requires no explanation.

Almost everyone will grant that knowledge is often transmitted through testimony. Indeed, to deny this would be to accept a broad-ranging skepticism. Here is a problem: Knowledge seems to be transmitted right along side lots of garbage. That is, besides transmitting genuine knowledge, we manage to transmit lots of beliefs that are irrational, superstitious, self-deceiving, and flat out false. So how is that possible? How is it that the very same channels manage to transmit both knowledge and garbage together? Call (...) this “the garbage problem”. Part One of the paper explicates the problem in more detail and argues that the problem seems unsolvable by some familiar approaches to testimonial knowledge. Part Two presents and begins to defend a solution. The general idea is to treat the garbage problem as a generality problem. (shrink)

Historically, the hypothesis that our world is a computer simulation has struck many as just another improbable-but-possible “skeptical hypothesis” about the nature of reality. Recently, however, the simulation hypothesis has received significant attention from philosophers, physicists, and the popular press. This is due to the discovery of an epistemic dependency: If we believe that our civilization will one day run many simulations concerning its ancestry, then we should believe that we are probably in an ancestor simulation right now. This essay (...) examines a troubling but underexplored feature of the ancestor-simulation hypothesis: the termination risk posed by both ancestor-simulation technology and experimental probes into whether our world is an ancestor simulation. This essay evaluates the termination risk by using extrapolations from current computing practices and simulation technology. The conclusions, while provisional, have great implications for debates concerning the fundamental nature of reality and the safety of contemporary physics. (shrink)

The inference that things do not matter because they will end is a source of despair for reflective people that features in literature, popular culture, and philosophy. Are there sound arguments in support of the inference? I first review three arguments that have been put forward in the existing philosophical literature and consider the objections that can be made against them. While the objections appear persuasive, these arguments do not exhaust the plausible justifications for the inference. Drawing on examples from (...) philosophy and literature, I introduce two previously undiscussed time-bias arguments in support of the inference that seem to be psychologically powerful. I conclude, however, that the time-bias arguments are also unsound. They involve an inconsistent shift between a temporally neutral and a temporally biased perspective on how the passage of time affects what matters. However the inconsistency is resolved, the conclusion does not follow. (shrink)

Here are three (rough) theories of testimonial knowledge. (1) Speaker's knowledge: a hearer acquires the knowledge that P though testimony because of the speaker's knowledge that P--testimony "transfers" knowledge. This is the popular view, defended by Elizabeth Fricker and Paul Faulkner, among others. (2) Speaker's assertion: a hearer acquires the knowledge that P through testimony because the speaker's assertion that P is reliable that P in the right way (safe or sensitive). That's Jennifer Lackey's view. (3) Speaker's comprehension state: a (...) hearer acquired the knowledge that P through comprehending as of a speaker's assertion that P where the comprehension state is reliable in the right way (safe). That's my view. Lackey would reject such a view for it allows cases of testimonial knowledge that P from a speaker who did not assert that P. But Faulkner might reject Lackey's view on the grounds that it allows cases of testimonial knowledge that P from a speaker who did not know that P. Lackey replies that her account is better unified. But for the same reason, my account is even better unified. This paper runs through a series of cases and shows that my account--the Unified Account--is superior to the others. (shrink)

If you want to understand McDowell's spatial metaphors when he talks about perceptual knowledge, place him side-by-side with Dretske on perceptual knowledge. Though McDowell shows no evidence of reading Dretske's writings on knowledge from the late 1960s onwards (McDowell mentions "Epistemic Operators" once in passing), McDowell gives the same four arguments as Dretske for the conclusion that knowledge requires "conclusive" reasons that rule of the possibility of mistake. Despite various differences, we think it is best to read McDowell as re-discovering (...) Dretske on perceptual knowledge. Since Dretske is easy to understand, all of McDowell's metaphors become easy to understand. But what about McDowell's disjunctivism? Turns out McDowell is not an ontological disjunctivist, and his epistemological disjunctivism is really just the banal point that some perceptual experiences provide conclusive reasons for perceptual belief and some do not. Perceptual experiences are either conclusive or inconclusive. Dretske would agree. (shrink)

Jennifer Lackey ('Testimonial Knowledge and Transmission' The Philosophical Quarterly 1999) and Peter Graham ('Conveying Information, Synthese 2000, 'Transferring Knowledge' Nous 2000) offered counterexamples to show that a hearer can acquire knowledge that P from a speaker who asserts that P, but the speaker does not know that P. These examples suggest testimony can generate knowledge. The showpiece of Lackey's examples is the Schoolteacher case. This paper shows that Lackey's case does not undermine the orthodox view that testimony cannot generate knowledge. (...) This paper explains why Lackey's arguments to the contrary are ineffective for they misunderstand the intuitive rationale for the view that testimony cannot generate knowledge. This paper then elaborates on a version of the case from Graham's paper 'Conveying Information' (the Fossil case) that effectively shows that testimony can generate knowledge. This paper then provides a deeper informative explanation for how it is that testimony transfers knowledge, and why there should be cases where testimony generates knowledge. (shrink)

I am a person. But am I fundamentally and essentially a person? The animalist says no. So must the phenomenal continuity theorist, or so I will argue. Even if, contra animalism, we cannot survive zombification, being a subject of experience is not sufficient for being a person, and phenomenal continuity is not sufficient for our survival as the same person over time. These observations point the way to a positive account of personhood, and provide further insight into the conditions under (...) which literal survival preserves what matters. (shrink)

In work on the ethics of cognitive enhancement use, there is a pervasive concern that such enhancement will—in some way—make us less authentic. Attempts to clarify what this concern amounts to and how to respond to it often lead to debates on the nature of the “true self” and what constitutes “genuine human activity”. This paper shows that a new and effective way to make progress on whether certain cases of cognitive enhancement problematically undermine authenticity is to make use of (...) considerations from the separate debate on the nature of authentic emotion. Drawing in particular on Wasserman and Liao, the present paper offers new conditions that can help us assess the impact of cognitive enhancements on authenticity. (shrink)

Scepticism is sometimes expressed about whether there is any interesting problem of other minds. In this paper I set out a version of the conceptual problem of other minds which turns on the way in which mental occurrences are presented to the subject and situate it in relation to debates about our knowledge of other people's mental lives. The result is a distinctive problem in the philosophy of mind concerning our relation to other people.

The aim of this paper is to study interpretation, specifically, to work toward an account of interpretation that seems descriptively and explanatorily correct. No account of interpretation can be philosophically helpful, I submit, if it is incompatible with a correct account of what people actually do when they interpret others. My question, then, is: how does the (naive) interpreter arrive at his/her judgments about the mental attitudes of others? Philosophers who have addressed this question have not, in my view, been (...) sufficiently psychological, or cognitivist, even those who are otherwise psychologically inclined. I shall defend some proposals about the activity of interpretation that are, I believe, psychologically more realistic than their chief competitors. (shrink)

As the Roman philosopher Lucretius asked, why do we fear and regret death, but do not regret not having been born earlier, when death and prenatal nonexistence are mirror images? Both deprive us of goods we might have had, and this deprivation most plausibly explains the badness of death. This paper first considers and rejects explanations other than the deprivation of goods. It then suggests an explanation in terms of a state of which death deprives us, and which is itself (...) asymmetrical in regard to the future and the past. This sharp asymmetry in this one very important good helps to justify the difference in our attitudes, especially among those for whom death approaches. The paper departs from the usual rigid format in which a philosopher says what she is going to say, then says it, and then repeats it. In matching form to mystery content, the missing clue to the solution will not be revealed until later in the paper. (shrink)

Corroborative evidence may be understood as having two epistemic effects: a primary effect by which it offers direct evidence for some claim, and a secondary effect by which it bolsters the appraised probative, or evidential, value of some other piece of evidence for that claim. This paper argues that the bolstering effect of corroborative evidence is epistemically legitimate because corroboration provides a reason to count the belief based on the initial evidence as sensitive to, and safe from, defeat in a (...) way that it was not previously recognized to be. Discovering that our initial evidence tracks the truth in a way we previously did not recognize provides a reason to positively reappraise the probative value of that evidence. The final section of the paper relates the proposed sensitivity- and safety-based account of corroboration to an explanation-based account. (shrink)

El objeto de este análisis es examinar —naturalmente, de un modo introductorio— cuál puede ser la repercusión de los eventuales avances en los objetivos transhumanistas en el terreno de la responsabilidad criminal.

This paper presents a new argument for the likelihood ratio measure of confirmation by showing that one of the adequacy criteria used in another argument can be replaced by a more plausible and better supported criterion which is a special case of the weak likelihood principle. This new argument is also used to show that the likelihood ratio measure is to be preferred to a measure that has recently received support in the literature.

What is a duty of justice? And how is it different from a duty of beneficence? We need a clear account of the contrast. Unfortunately, there is no consensus in the philosophical literature as to how to characterize it. Different articulations of it have been provided, but it is hard to identify a common core that is invariant across them. In this paper, I propose an account of how to understand duties of justice, explain how it contrasts with several proposals (...) as to how to distinguish justice and beneficence, respond to some objections and suggest further elaborations of it. The conceptual exploration pursued in this paper has practical stakes. A central aim is to propose and defend a capacious concept of justice that makes a direct discussion of important demands of justice (domestic and global) possible. Duties of justice can be positive besides negative, they can be imperfect as well as perfect, they can range over personal besides institutional contexts, they can include multiple associative reasons such us non-domination, non-exploitation and reciprocity, and they can even go beyond existing national, political, and economic associative frameworks to embrace strictly universal humanist concerns. We should reject ideological abridgments of the concept of justice that render these possibilities, and the important human interests and claims they may foster, invisible. (shrink)

This essay presents a unified account of safety, sensitivity, and severe testing. S’s belief is safe iff, roughly, S could not easily have falsely believed p, and S’s belief is sensitive iff were p false S would not believe p. These two conditions are typically viewed as rivals but, we argue, they instead play symbiotic roles. Safety and sensitivity are both valuable epistemic conditions, and the relevant alternatives framework provides the scaffolding for their mutually supportive roles. The relevant alternatives condition (...) holds that a belief is warranted only if the evidence rules out relevant error possibilities. The safety condition helps categorise relevant from irrelevant possibilities. The sensitivity condition captures ‘ruling out’. Safety, sensitivity, and the relevant alternatives condition are typically presented as conditions on warranted belief or knowledge. But these properties, once generalised, help characterise other epistemic phenomena, including warranted inference, legal verdicts, scientific claims, reaching conclusions, addressing questions, warranted assertion, and the epistemic force of corroborating evidence. We introduce and explain Mayo’s severe testing account of statistical inference. A hypothesis is severely tested to the extent it passes tests that probably would have found errors, were they present. We argue Mayo’s account is fruitfully understood using the resulting relevant alternatives framework. Recasting Mayo’s condition using the conceptual framework of contemporary epistemology helps forge fruitful connections between two research areas—philosophy of statistics and the analysis of knowledge—not currently in sufficient dialogue. The resulting union benefits both research areas. (shrink)

Epistemological accounts that make use of a safety condition on knowledge, historically, face serious problems regarding beliefs that are necessarily true. This is because necessary truths are true in all possible worlds, so such beliefs can be safe even when the bases for the beliefs are epistemically problematic. The existence of such problematically safe beliefs would undermine a major motivation for the condition itself: the ability to evaluate how well a belief tracks the truth. In this paper, we’ll argue that (...) incorporating impossible worlds into the evaluation of beliefs solves this problem, but only if the relevant account of impossible worlds entails that many impossible worlds are incredibly similar to the actual world. Further, we’ll argue that, as a result of including impossible worlds, some philosophical beliefs are unsafe, and many more are potentially unsafe. But, we argue, even if this is the case, we can still make philosophical progress. (shrink)

Richard Rorty's recent death has unleashed a strikingly mixed judgment of his philosophical legacy, ranging from claims to originality to charges of charlatanry. What is clear, however, is Rorty's role in articulating a distinctive American voice in the history of philosophy. He achieved this not only through his own wide-ranging contributions but also by repositioning the pragmatists, especially William James and John Dewey, in the philosophical mainstream. Rorty did for the United States what Hegel and Heidegger had done for Germany—to (...) portray his nation as philosophy's final resting place. He was helped by postwar German philosophers like Jürgen Habermas who were happy to defer to their American conquerors. Rorty's philosophical method can be understood as a sublimation of America's world-historic self-understanding: a place suspicious of foreigners unless they are willing to blend into the "melting pot." In retrospect, the breadth and confidence of Rorty's writing will come to symbolize the moment when the United States, for better or worse, came to be the world's dominant philosophical power. Key Words: Rorty • pragmatism • logical positivism • analytic philosophy. (shrink)

Temporal nihilism is the view that our lives won’t matter after we die. According to the standard interpretation, this is because our lives won’t make a permanent difference. Many who consider the view thus reject it by denying that our lives need to have an eternal impact. However, in this paper, I develop a different formulation of temporal nihilism revolving around the persistence of personal value itself. According to this stronger version, we do not have personal value after death, so (...) our past life no longer has wellbeing after we die. The standard objections to the standard interpretation don’t apply to this more nihilistic nihilism. I offer a new response according to which personal value persists after death because the person continues to exist. (shrink)

We report a series of experiments examining whether people ascribe knowledge for true beliefs based on probabilistic evidence. Participants were less likely to ascribe knowledge for beliefs based on probabilistic evidence than for beliefs based on perceptual evidence or testimony providing causal information. Denial of knowledge for beliefs based on probabilistic evidence did not arise because participants viewed such beliefs as unjustified, nor because such beliefs leave open the possibility of error. These findings rule out traditional philosophical accounts for why (...) probabilistic evidence does not produce knowledge. The experiments instead suggest that people deny knowledge because they distrust drawing conclusions about an individual based on reasoning about the population to which it belongs, a tendency previously identified by “judgment and decision making” researchers.

After showing that this argument cannot be avoided by denying scarcity, I consider four challenges to the argument which accept the possibility of conflicts between the duties implied by rights. The first denies the agglomeration principle; the second embraces conflicts of duties; the third affirms the violability of all rights-based duties; and the fourth denies that duties to compensate are overriding. I argue that all four challenges to the scarcity argument are (...) unsuccessful. I then discuss Eddy’s recent challenge, which makes welfare rights context dependent, but I argue that this also fails because it makes rights unknowable. I conclude that the scarcity argument, restated in the light of the discussion, shows that universal welfare rights, as ordinarily understood, are impossible and I explain the philosophical and practical significance of this conclusion.

The chance objection to incompatibilist accounts of free action maintains that undetermined actions are not under the agent's control. Some attempts to circumvent this objection locate chance in events posterior to the action. Indeterministic-causation theories locate chance in events prior to the action. However, neither type of response gives an account of free action which avoids the chance objection. Chance must be located at the act of will if actions are to be both undetermined and under the agent's control. This (...) dissolves the apparent paradox of Frankfurt-type cases as well as the chance objection to incompatibilist free will. (shrink)
