In “Normativity and Epistemic Intuitions”, Weinberg, Nichols and Stich famously argue from empirical data that East Asians and Westerners have different intuitions about Gettier -style cases. We attempted to replicate their study about the Car case, but failed to detect a cross - cultural difference. Our study used the same methods and case taken verbatim, but sampled an East Asian population 2.5 times greater than NEI’s 23 participants. We found no evidence supporting the existence of cross - (...) cultural difference about the intuition concerning the Gettier car case. Taken together with the failures of both of the existing replication studies, our results provide strong evidence that the purported cross - cultural difference in Gettier intuitions does not exist.

In this paper, I respond to Philip Atkins’ reply to my attempt to explain why Gettier cases (and Gettier-style cases) are misleading. I have argued that Gettier cases (and Gettier-style cases) are misdealing because the candidates for knowledge in such cases contain ambiguous designators. Atkins denies that Gettier’s original cases contain ambiguous designators and offers his intuition that the subjects in Gettier’s original cases do not (...) know. I argue that his reply amounts to mere intuition mongering and I explain why Gettier cases, even Atkins’ revised version of Gettier’s Case I, still contain ambiguous designators. (shrink)

Knowledge of the basic rules of logic is often thought to be distinctive, for it seems to be a case of non-inferential a priori knowledge. Many philosophers take its source to be different from those of other types of knowledge, such as knowledge of empirical facts. The most prominent account of knowledge of the basic rules of logic takes this source to be the understanding of logical expressions or concepts. On this account, what explains why such knowledge is distinctive is (...) that it is grounded in semantic or conceptual understanding. However, I show that this cannot be the correct account of knowledge of the basic rules of logic, because it is open to Gettier-style counter-examples. (shrink)

Knowledge sets the standard for appropriate assertion and recent evidence suggests that it might also set the standard for appropriate belief and decision‐making. Governments spend hundreds of millions of dollars to support the creation, transfer, and mobilization of knowledge. Philosophers have created a dizzying array of Gettier case thought experiments. In doing so, many have been guilty of experimenter bias. This includes some original players who helped set the agenda for decades to come. Cognitive scientists recently began seriously investigating (...) knowledge judgments. The study of Gettier cases was motivated by work in psychology showing important cultural differences in reasoning styles and moral judgments. The nominal category Gettier case includes a variety of cases with radical structural differences that are extremely important in both theory and ordinary practice, so important as to render the nominal category, as the authors have inherited it, utterly useless.

It has been pointed out that Gettier case scenarios have deviant realizations and that deviant realizations raise a difficulty for the logical analysis of thought experiments. Grundmann and Horvath have shown that it is possible to rule out deviant realizations by suitably modifying the scenario of a Gettier-style thought experiment. They hypothesize further that the enriched scenario corresponds to the way expert epistemologists implicitly interpret the original one. However, no precise account of this implicit enrichment is offered, (...) which makes the proposal somewhat ad hoc. Drawing on pragmatic theory, I argue that the content of Grundmann and Horvath’s modified scenario corresponds to the default interpretation of the original scenario and that epistemological expertise is not required to access the deviance-proof interpretation. This Default Interpretation proposal offers thus a more general and independently motivated solution to the Problem of Deviant Realizations. (shrink)

PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this (...) book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing... (shrink)

The paper analyzes the problem of interpretations of the Gettier problem. The author draws a distinction between counterexamples presented in Edmund Gettier’s article and Gettier-style cases, between the Gettier problem and general epistemological problem supposedly occurring in all or many Gettier-style cases. It is argued that in Gettier’s article there is a gap associated with an insufficiently defined concept of justification, which does not allow talking about Gettier problem without (...) any explicit or implicit interpretation of his views on justification. Along with this, it is indicated that the same concept of justification has strict features (deductive closure principle, non-factive justification and internalism), which do not allow arbitrary interpretations of the Gettier problem, and therefore we can say that some interpretations are closer to the text of a well-known article.

A U-shaped curve in a cognitive-developmental trajectory refers to a three-step process: good performance followed by bad performance followed by good performance once again. U-shaped curves have been observed in a wide variety of cognitive-developmental and learning contexts. U-shaped learning seems to contradict the idea that learning is a monotonic, cumulative process and thus constitutes a challenge for competing theories of cognitive development and learning. U-shaped behavior in language learning (in particular in learning English past tense) has become a central (...) topic in the Cognitive Science debate about learning models. Antagonist models (e.g., connectionism versus nativism) are often judged on their ability of modeling or accounting for U-shaped behavior. The prior literature is mostly occupied with explaining how U-shaped behavior occurs. Instead, we are interested in the necessity of this kind of apparently inefficient strategy. We present and discuss a body of results in the abstract mathematical setting of (extensions of) Gold-style computational learning theory addressing a mathematically precise version of the following question: Are there learning tasks that require U-shaped behavior? All notions considered are learning in the limit from positive data. We present results about the necessity of U-shaped learning in classical models of learning as well as in models with bounds on the memory of the learner. The pattern emerges that, for parameterized, cognitively relevant learning criteria, beyond very few initial parameter values, U-shapes are necessary for full learning power! We discuss the possible relevance of the above results for the Cognitive Science debate about learning models as well as directions for future research. (shrink)

A growing body of empirical evidence suggests that folk knowledge attribution practices regarding some epistemological thought experiments differ significantly from the consensus found in the philosophical literature. More specifically, laypersons are likely to ascribe knowledge in the so-called Authentic Evidence Gettier-style cases, while most philosophers deny knowledge in these cases. The intuitions shared by philosophers are often used as evidence in favor (or against) certain philosophical analyses of the notion of knowledge. However, the fact that these (...) intuitions are not universal, as non-philosophers do not sympathize with verdicts made by philosophers, is problematic and requires some explanation. Recently, a promising theoretical approach emerged that could be used to explain away unexpected folk knowledge attributions. According to the protagonist projection hypothesis, when subjects answer questions about some hypothetical scenario, their judgments might result from adopting the cognitive perspective of the protagonist in the given scenario. Previous experimental findings suggest protagonist projection might be responsible for problematic knowledge attributions in Gettier-style cases. This paper reports data collected in an experiment which focused on five different Authentic Evidence Gettier-style scenarios and investigated the impact of protagonist projection on folk knowledge ascriptions in such cases. The results bring some support to the protagonist projection hypothesis, but do not allow to explain away a substantial number of problematic folk knowledge attributions. (shrink)

‘Frankfurt-style cases’ (FSCs) are widely considered as having refuted the Principle of Alternate Possibilities (PAP) by presenting cases in which an agent is morally responsible even if he could not have done otherwise. However, Neil Levy (J Philos 105:223–239, 2008) has recently argued that FSCs fail because we are not entitled to suppose that the agent is morally responsible, given that the mere presence of a counterfactual intervener is enough to make an agent lose responsibility-grounding abilities. Here, (...) I distinguish two kinds of Frankfurt counter-arguments against the PAP: the direct and the indirect counter-arguments. I then argue that Levy’s argument, if valid, can shed doubt on the indirect argument but leaves the direct argument untouched. I conclude that FSCs can still do their job, even if we grant that the mere presence of a counterfactual intervener can modify an agent’s abilities. (shrink)

Frankfurt-style cases are supposed to constitute counter-examples to the principle of alternate possibilities, for they are cases in which we have the intuition that an agent is morally responsible for his action, even though he could not have done otherwise. In a recent paper, Swenson rejects this conclusion, on the basis of a comparison between standard FSCs, which typically feature actions, and similar cases involving omissions. Because the absence of alternate possibilities seems to preclude moral responsibility (...) in the cases of omissions, and because there is no morally relevant difference between the cases of actions and omissions, Swenson concludes that agents are not morally responsible in standard FSCs. In the present paper, I argue that Swenson’s argument fails because there are at least two very important differences between both types of cases. First, there is a difference about whether agents in such cases actually perform the relevant action: while agents actually perform the relevant action in standard FSCs, they do not in FSCs supposedly involving omissions, for omissions require the possibility to have done otherwise. Second, while the agent’s behavior in standard FSCs actually explain that he performed the relevant action, the agent’s behavior in FSCs including omission actually fails to explain why the agent did not perform the relevant action. Beyond Swenson’s argument, I end up discussing what factors ultimately explain our intuitions about FSCs involving omissions. (shrink)

This chapter analyzes the logical structure of Edmund Gettier‐style thought experiments. The discussion can be generalized to many imaginary counterexamples that have been deployed against philosophical analyses and theories in ways more or less similar to Gettier’s. The background working hypothesis is that his thought experiments are paradigmatic, in the sense that if any thought experiments can succeed in philosophy, his do: thus to determine whether Gettier’s thought experiments succeed is in effect to determine whether there (...) can be successful thought experiments in philosophy. Gettier presents his specific counterexamples to the target analysis through short fictional narratives, in the present tense indicative, with fictional uses of proper names, all introduced by “suppose that.” One manifestation of the influence of past experience on epistemological judgments may be cross‐cultural variation in verdicts on thought experiments, including the Gettier case.

The lottery problem is the problem of explaining why mere reflection on the long odds that one will lose the lottery does not yield knowledge that one will lose. More generally, it is the problem of explaining why true beliefs merely formed on the basis of statistical evidence do not amount to knowledge. Some have thought that the lottery problem can be solved by appeal to a violation of the safety principle for knowledge, i.e., the principle that if S knows (...) that p, not easily would S have believed that p without p being the case. Against the standard safety‐based solution, I argue that understanding safe belief as belief that directly covaries with the truth of what is believed in a suitably defined set of possible worlds forces safety theorists to make a series of theoretical choices that ultimately prevent a satisfactory solution to the problem. In this way, I analyze several safety principles that result from such choices—the paper thus gives valuable insights into the nature of safety—and explain why none solves the lottery problem, including their inability to explain away Gettierized lottery cases. On a more positive note, I show that there is a viable solution in terms of safety if we get rid of the unquestioned assumption that safe beliefs directly track the truth. The alternative is a conception of safe belief according to which what safe beliefs directly track is the appropriateness of the circumstances and, indirectly, the truth. The resulting safety principle, I argue, explains why mere statistical evidence is not a safe source of knowledge. (shrink)

According to the most popular versions of the flicker defense, Frankfurt-style cases fail to undermine the Principle of Alternative Possibilities (PAP) because agents in these cases are (directly) morally responsible not for making the decisions they make but for making these decisions on their own, which is something they could have avoided doing. Frankfurt defenders have primarily focused on trying to show that the alternative possibility of refraining from making the relevant decisions on their own is not (...) a robust alternative, while generally granting that this alternative cannot easily be eliminated from successful cases of this sort. In a recent issue of this journal, Stockdale (2022) attempts to sidestep the debate concerning robustness and develops a novel kind of Frankfurt-style case in which agents are unable to avoid making the relevant decisions on their own. The fundamental problem with Stockdale’s argument is that it hinges on an implausible conception of acting on one’s own. I help clarify the pertinent sense of what it means to do a thing on one’s own in this context and show that these new cases are unable to overcome the targeted versions of the flicker defense of PAP.

This chapter addresses the issue of the underrepresentation of women in philosophy by presenting an account regarding gender differences in philosophical institutions. It begins with an analysis of data on the gender gap in academic philosophy; followed by a discussion about the term “intuition,”as well as the tendency to appeal to intuitions during philosophical arguments. It then presents empirical data about gender differences derived from a series of experiments such as a Gettier-style case study of Christina Starmans and (...) Ori Friedman, a philosophical thought experiment of Geoffrey Holtzman, and one of David Pizarro about moral responsibility and causal deviance, among others; one hypothesis derived from these studies pertains to the distinct differences between women and mens' intuitions regarding philosophy, with the instructors deciding that the mens' are more correct.

Frankfurt-Style Cases (FSCs) seem to elicit the intuitive judgment that an agent is morally responsible despite being unable to act otherwise, which is supposed to falsify the Principle of Alternative Possibility (PAP). Recent empirical studies have shown that the inclination toward this intuitive judgment is shared among people, which seems to reinforce the argument against the PAP. However, some scholars have argued for Descriptive Anti-Intuitionism (DAI) — intuitive judgments have never played an evidential role in philosophy — and (...) thus denied the philosophical significance of such empirical findings. I point out that although DAI fails in its literal claim for FSCs, an associated insight remains potent: an intuitive judgment is so fragile that it can be easily defeated by further arguments. Nevertheless, I argue, empirical studies are significant in uncovering the general principles to which we are committed in our practice concerning moral responsibility. I clarify how such findings can play a robust evidential role in philosophical debates concerning moral responsibility by tracing the literature written by Frankfurt and philosophers. (shrink)

The new dispositionalists defend the position that an agent in a deterministic Frankfurt-style case has the ability to do otherwise, where that ability is the one at issue in the principle of alternative possibilities. Focusing specifically on Kadri Vihvelin's proposal, I argue against this position by showing that it is incompatible with the existence of structurally similar cases to FSCs in which a preemptive intervener bestows an agent with an ability.

According to the No-Luck-Thesis knowledge possession is incompatible with luck – one cannot know that p if the truth of one’s belief that p is a matter of luck. Recently, this widespread opinion was challenged by Peter Baumann, who argues that in certain situations agents do possess knowledge even though their beliefs are true by luck. This paper aims at providing empirical data for evaluating Baumann’s hypothesis. The experiment was designed to compare non-philosophers’ judgments concerning knowledge and luck in one (...) case that Baumann takes to be in favor of his claim and other cases where, according to him, absence of knowledge coincides with luck. The results show that the cases do not differ in a significant way between each other with respect to verdicts regarding knowledge and luck. In all cases subjects were more reluctant to judge that the ‘Gettierized’ belief is knowledge and more likely to judge that it is true by luck in comparison to a belief that is an uncontroversial instance of knowledge. However, the negative relationship between knowledge and luck ascriptions predicted by the No-Luck-Thesis was almost absent. The data raise some doubts about the No-Luck-Thesis, but the reasons for doubt are different than what Baumann expected. (shrink)

Over the years, two models of freedom have emerged as competitors: the alternative-possibilities model, which states that acting freely consists in being able to do otherwise, and, more recently, the actual-sequence model, which states that acting freely is exclusively a function of the actual sequence of events issuing in our behavior. In general, a natural strategy when trying to decide between two models of a certain concept is to look for examples that support one model and undermine the other. Frankfurt- (...) class='Hi'>style cases have been used for this kind of purpose, to challenge the alternative-possibilities view and support the actual-sequence view. In this paper I examine the prospects of the counterparts of Frankfurt-style cases: “PAP-style” cases, or cases that could be used to support the alternative-possibilities view and challenge the actual-sequence view. I argue that there are no successful PAP-style cases. (shrink)

“Frankfurt-style cases” are widely considered as having refuted the Principle of Alternate Possibilities by presenting cases in which an agent is morally responsible even if he could not have done otherwise. However, Neil Levy has recently argued that FSCs fail because our intuitions about cases involving counterfactual interveners are inconsistent, and this inconsistency is best explained by the fact that our intuitions about such cases are grounded in an internalist prejudice about the location of mental (...) states and capacities. In response to this challenge, we argue that there is no inconsistency in our intuitions about cases involving CIs, as soon as we draw the comparison properly, and that intuitions about such cases do not rest on an internalist prejudice, but on a more basic distinction between two kinds of dispositions. Additionally, we discus... (shrink)

Retributive theories of punishment argue that punishing a criminal for a crime she committed is sufficient reason for a justified and morally permissible punishment. But what about when the state gets lucky in its decision to punish? I argue that retributive theories of punishment are subject to “Gettier” style cases from epistemology. Such cases demonstrate that the state needs more than to just get lucky, and as these retributive theories of punishment stand, there is no anti-luck (...) condition. I’ll argue that Gettier-style cases demonstrate an impermissible instance of punishment, even though they meet the conditions of retributive theories of punishment. Retributive theories are, therefore, too weak. The safety condition from epistemology provides the anti-luck condition needed for permissible punishment. I argue that two forms of retributivism, rights-forfeiture and what I call standard retributivism, are both subject to Gettier-style cases. Unlike the literature on standards of proof, this paper argues that safety is a condition on punishment itself, i.e., in all nearby possible worlds, the accuser must correctly accuse the convicted for the crime they actually committed.

It has been argued that a successful counterexample to the principle of alternative possibilities must rule out any possibility of the agent making an alternative decision right up to the moment of choice. This paper challenges that assumption. Distinguishing between an ability and an opportunity, this paper presents a Frankfurt-style case in which there is an alternative possibility, but one it is highly improbable that the agent will access. In such a case the agent has only the opportunity, not (...) the ability to do otherwise. (shrink)

ABSTRACT The Frankfurt-style Counterexamples to the Principle of Alternative Possibilities have been controversial. I sketch some of the major moves in the debates surrounding the FSCs, and I seek to provide an answer to a big challenge: the indeterministic horn of the ‘dilemma defense’. Given indeterminism, it is unclear how Black can know with certainty what Jones will choose and do in the future; this leaves at least some open alternatives for Jones. I adopt the strategy of positing God (...) in Black’s place. The challenge now is to explain how God can have knowledge with certainty of future free human behavior in an indeterministic context, insofar as there is no entailing evidence in available in advance in such a situation. I present the Bootstrapping View of God’s knowledge to solve this problem. If we replace Black with God, we have an indeterministic case in which an agent acts freely, and yet cannot do otherwise. My account of God’s knowledge provides an interpretation of Luis de Molina’s notoriously obscure notion of Supercomprehension. (shrink)

This is a critical discussion of Vihvelin’s recent book Causes, Laws, and Free Will. I discuss Vihvelin’s ideas on Frankfurt-style cases and the actual-sequence view of freedom that is inspired by them.

In his “Frankfurt-style cases user manual”, Florian Cova (2013) distinguishes two kinds of Frankfurt-style arguments against the principle of alternative possibilities (PAP), and argues that my attack on the soundness of Frankfurt-style cases succeeds, at most, only against one kind. Since either kind of argument can be used to undermine PAP, Cova suggests, the fact that my attack fails against at least one means that it does not succeed in rescuing PAP from the clutches of (...) Frankfurt enthusiasts. In this brief response I will argue that my attack undermines both kinds of Frankfurt-style arguments. It shows that we are not entitled to rely on the intuitions that these arguments provoke, whether they are produced by the direct version of the Frankfurt-style argument or the indirect.In a typical Frankfurt-style case (FSC), an agent performs a bad action for which, intuitively, they seem to be morally responsible, despite the fact that they lack alternative possibilities (see Frankfurt 196. (shrink)

The claim that moral responsibility requires relevant alternative possibilities is encapsulated by the following principle: PAP: A person is morally responsible for what he has done only if he could have done otherwise. In 1969 Harry Frankfurt devised what purported to be a counterexample to PAP: Suppose someone, Black, let us say, wants Jones to perform a certain action. Black is prepared to go to considerable lengths to get his way, but he prefers to avoid showing his hand unnecessarily. So (...) he waits until Jones is about to make up his mind what to do, and he does nothing unless it is clear to him that Jones is going to decide to do something other than what he, Black, wants him to do. If it does become clear that Jones is going to decide to do something else, Black takes effective steps to ensure that Jones decides to do, and that he does do, what he, Black, wants him to do. Whatever Jones's initial preferences and inclinations, then, Black will have his way. . . . Now suppose that Black never has to show his hand because Jones, for reasons of his own, decides to perform and does perform the very action Black wants him to perform. In that case, it seems clear, Jones will bear precisely the same moral responsibility for what he does as he would have borne if Black had not been ready to take steps to ensure that he do it.

Almost thirty years ago, in an attempt to undermine what he termed "the principle of alternate possibilities" (the thesis that people are morally responsible for what they have done only if they could have done otherwise), Harry Frankfurt offered an ingenious thought-experiment that has played a major role in subsequent work on moral responsibility and free will. Several philosophers, including David Widerker and Robert Kane, argued recently that this thought-experiment and others like it are fundamentally flawed. This paper develops a (...) new Frankfurt-style example that is immune to their objections.

The so–called truthmaker solution to the problem Gettier is thought to have posed for the analysis of knowledge as justified true belief is to add a fourth condition, requiring that one’s evidence for one’s belief be the state of affairs that makes the belief true. Adrian Heathcote argues that the reason why one lacks knowledge in Russell’s case of the stopped clock is that, as in the classic Gettier–style cases, this condition is not satisfied. I argue (...) that the proposed solution fails, as it embodies a misunderstanding of what evidence is. (shrink)

We investigate the impact of informal arguments on judgments about thought experiment cases in light of Deutsch and Cappelen’s mischaracterization view, which claims that philosophers’ case judgments are primarily based on arguments and not intuitions. If arguments had no influence on case judgments, this would seriously challenge whether they are, or should be, based on arguments at all—and not on other cognitive sources instead, such as intuition. In Experiment 1, we replicated Wysocki’s (Rev Philos Psychol 8(2):477–499, 2017) pioneering study (...) on a Gettier-style case, and we confirmed that the informal arguments used by him had no significant effect. However, we also included an improved argument for ascribing knowledge, which did have a significant effect even in Wysocki’s original design. We therefore followed up with Experiment 2 on three Gettier-style cases, where we used a more natural dialogical format for presenting both case descriptions and informal arguments. Overall, we found a clear impact of prima facie good pro and con arguments on case judgments. The issue of argument impact is thus no obstacle to arguing about thought experiments. (shrink)

Frankfurt-style cases are widely taken to show that agents do not need alternative possibilities to be morally responsible for their actions. Many philosophers take these cases to constitute a powerful argument for compatibilism: if we do not need alternative possibilities for moral responsibility, it is hard to see what the attraction of indeterminism might be. I defend the claim that even though Frankfurt-style cases establish that agents can be responsible for their actions despite lacking alternatives, (...) agents can only be responsible if they possess certain powers, and possession of these powers is - arguably - incompatible with determinism. Because this is the case, Frankfurt-style cases fail to advance the debate between compatibilism and incompatibilism. (shrink)

In a recent article in this journal, Wolfgang Freitag argues that Gettier-style cases that are based on the notion of “distant” epistemic luck cannot be ruled out as cases of knowledge by modal conditions such as safety or sensitivity. I argue that safety and sensitivity can be easily fixed and that Freitag provides no convincing reason for the existence of “distant” epistemic luck.

According to the most popular versions of the flicker defense, Frankfurt-style cases fail to undermine the Principle of Alternative Possibilities (PAP) because agents in these cases are (directly) morally responsible not for making the decisions they make but for making these decisions on their own, which is something they could have avoided doing. Frankfurt defenders have primarily focused on trying to show that the alternative possibility of refraining from making the relevant decisions on their own is not (...) a robust alternative, while generally granting that this alternative cannot easily be eliminated from successful cases of this sort.

The fundamental problem with Stockdale’s argument is that it hinges on an implausible conception of acting on one’s own. I help clarify the pertinent sense of what it means to do a thing on one’s own in this context and show that these new cases are unable to overcome the targeted versions of the flicker defense of PAP.

In this article, I argue that fallibilistic justification is insufficient for propositional knowledge if veritic luck is involved. I provide a thought experiment to demonstrate that even very strong non-factive evidence is insufficient for knowledge if veritic luck is present. I then distinguish between precise justification, which I suggest is required for knowledge in cases of veritic luck, and loose justification, which is sufficient for practical cases in which beliefs are reasonable to hold even if they fall short (...) of being items of knowledge. In addition, I provide a reason for holding that PJ is required for all items of propositional knowledge, and not only for cases of veritic luck. Lastly, I propose that Gettier-style cases pertain to an ambiguity between PJ and LJ. (shrink)

A good part of the philosophical debate on free will and moral responsibility in the last fifty years has revolved around so-called Frankfurt-style cases. One of the most important milestones in this debate is the case described by Mele and Robb (1998), which was intended to avoid some earlier objections directed at Frankfurt’s original argument. However, the success of Mele and Robb’s case has been contested by Pereboom (2001), Widerker (2003), and Moya (2003, 2017), among others. The present (...) paper aims to vindicate Mele and Robb’s (and Frankfurt’s) general argument by describing a variation of their case that overcomes or avoids the objections of those authors.

Safety principles in epistemology are often hailed as providing us with an explanation of why we fail to have knowledge in Gettier cases and lottery examples, while at the same time allowing for the fact that we know the negations of sceptical hypotheses. In a recent paper, Sinhababu and Williams have produced an example—the Backward Clock—that is meant to spell trouble for safety accounts of knowledge. I argue that the Backward Clock case is, in fact, unproblematic for the (...) more sophisticated formulations of safety in the literature. However, I then proceed to construct two novel examples that turn out problematic for those formulations—one that provides us with a lottery-style case of safe ignorance and one that is a straightforward case of unsafe knowledge. If these examples succeed, then safety as it is usually conceived in the current debate cannot account for ignorance in all Gettier and lottery-style cases, and neither is it a necessary condition for knowledge. I conclude from these troublesome examples that modal epistemologists ought to embrace a much more simple and non-reductive version of safety, according to which the notion of similarity between possible worlds that determines in which worlds the subject must believe truly is an epistemic notion that cannot be defined or reduced to notions independent of knowledge. The resulting view is shown to also lead to desirable results with respect to lottery cases, certain quantum phenomena, and a puzzling case involving a cautious brain-in-a-vat. (shrink)

Philosophers employing Frankfurt-style cases to challenge the principle of alternative possibilities have mostly sought to construct scenarios that eliminate as many of an agent’s alternatives as possible—and all alternatives at the moment of action, within the agent’s control—without causally determining the agent’s actions. One of the chief difficulties for this traditional approach is that the closer one gets to ruling out absolutely all alternative possibilities the more it appears that agents’ actions in these cases are causally determined. (...) “Limited-blockage” versions of these cases are meant to sidestep this worry by blocking all and only those alternatives that are intrinsically relevant to moral responsibility (“robust alternatives”) while leaving open all other alternatives, including a significant range of alternatives that are within the agent’s voluntary control at the moment of action. I argue that, owing to the fact that omissions (and not just actions) are capable of constituting robust alternative possibilities, limited-blockage cases cannot avoid collapsing into the more traditional sort of Frankfurt-style case to which they are meant to be an alternative and so are vulnerable to the very same concerns they are meant to avoid.

The term “Gettier Case” is a technical term frequently applied to a wide array of thought experiments in contemporary epistemology. What do these cases have in common? It is said that they all involve a justified true belief which, intuitively, is not knowledge, due to a form of luck called “Gettiering.” While this very broad characterization suffices for some purposes, it masks radical diversity. We argue that the extent of this diversity merits abandoning the notion of a “ (...) class='Hi'>Gettier case” in a favour of more finely grained terminology. We propose such terminology, and use it to effectively sort the myriad Gettier cases from the theoretical literature in a way that charts deep fault lines in ordinary judgments about knowledge.

Frankfurt‐style cases suggest that an agent's moral responsibility for an action supervenes on the causal history of that action—at least when epistemic considerations are held constant. However, PAP‐style cases suggest that moral responsibility does not supervene on causal history, for judgments concerning an agent's responsibility for an action are also sensitive to the presence of alternative—and causally idle—possibilities. I appeal to the causal modeling tradition and the definitions of actual causation that derive therefrom in an attempt (...) to resolve this contradiction. I show that even the weakest definitions of actual causation proposed in the literature establish that some PAP‐style cases constitute genuine counterexamples to the supervenience thesis. I consider several responses to these counterexamples on behalf of the defenders of supervenience and show that they fail. Our best current thinking on causation thus appears to be inconsistent with an intuitive and widely held claim concerning the nature of moral responsibility. (shrink)

The orthodox view in contemporary epistemology is that Edmund Gettier refuted the JTB analysis of knowledge, according to which knowledge is justified true belief. In a recent paper Moti Mizrahi questions the orthodox view. According to Mizrahi, the cases that Gettier advanced against the JTB analysis are misleading. In this paper I defend the orthodox view.

In this paper Mele and Robb defend their (1998) paper against a variety of objections and further their develop their defense of Frankfurt-style cases.
