Critical discussion of Susanna Schellenberg's account of hallucination and perceptual evidence.

The target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically types of reflectance. This is probably a minority opinion, at least among color scientists. Textbooks frequently claim that physical objects are not colored, and that the colors are "subjective" or "in (...) the mind." The article has two other purposes: first, to introduce an interdisciplinary audience to some distinctively philosophical tools that are useful in tackling the problem of color realism and, second, to clarify the various positions and central arguments in the debate. (shrink)

Our reply is in three parts. The first part concerns some foundational issues in the debate about color realism. The second part addresses the many objections to the version of physicalism about color ("productance physicalism") defended in the target article. The third part discusses the leading alternative approaches and theories endorsed by the commentators.

Leiter (2016) charges public philosophy with being “neoliberal”. To understand that charge better, I define, in §1, three versions of public philosophy which might be concerned and two pictures of its practice targeted by Leiter. I also compare two deliberative sites wherein those pictures may play out. In §2, I sketch how Leiter’s two paradoxes for “neoliberal” public philosophy lead to a revised public philosophy. §3 questions the paradoxes’ empirical grounding and scope. Lastly, in §4, I assume Leiter’s picture and (...) illustrate how philosophical dialogue, through appeal to personal self-image and “moral perceptions”, may still influence public discourse. I conclude that Leiter both over- and understates his case and that his conclusions require greater scrutiny. (shrink)

In Burge [Disjunctivism and perceptual psychology. Philosophical Topics 33: 1–78, 2005], I criticized several versions of disjunctivism. McDowell defends his version against my criticisms in McDowell [Tyler Burge on disjunctivism. Philosophical Explorations 13: 243–55, 2010]. He claims that my general characterization fails to apply to his view. I show that this claim fails because it overlooks two elements in my characterization. I elaborate and extend my criticisms of his disjunctivism. I criticize his positions on infallibility and indefeasibility, and reinforce my (...) earlier charges that his views on perception and epistemology are hyper-intellectualized. The central point in my rejection of his disjunctivism concerns his claim that the science of perceptual psychology is irrelevant to his disjunctivist classification of perceptual states. I hold that this claim shows lack of familiarity with the science and serious misunderstanding of it. The basic deficiency in McDowell's disjunctivism is that it, like other versions, is incompatible with well-established scientific knowledge. (shrink)

Previous research in experimental philosophy has suggested that moral judgments can influence the ordinary application of a number of different concepts, including attributions of knowledge. But should epistemologists care? The present set of studies demonstrate that this basic effect can be extended to overturn intuitions in some of the most theoretically central experiments in contemporary epistemology: Gettier cases. Furthermore, experiment three shows that this effect is unlikely mediated by a simple desire to blame, suggesting that a correct psychological account of (...) ordinary knowledge attribution may include moral judgment.

A notorious objection to robust virtue epistemology—the view that an agent knows a proposition if and only if her cognitive success is because of her intellectual virtues—is that it fails to eliminate knowledge-undermining luck. Modest virtue epistemologists agree with robust virtue epistemologists that if someone knows, then her cognitive success must be because of her intellectual virtues, but they think that more is needed for knowledge. More specifically, they introduce independently motivated modal anti-luck principles in their accounts to amend the (...) problem of eliminating luck—this makes their views instances of impure virtue epistemology. The aim of the paper is to argue, firstly, that such a move lacks adequate motivation; secondly, that the resulting impure accounts equally fail to handle knowledge-undermining luck. On a more positive note, these results bolster a more orthodox virtue-theoretic approach to knowledge that assigns a fundamental explanatory role to the notion of ability. In this sense, the paper also sketches an account of ability and a corresponding account of knowledge that explains how success from ability is incompatible with success from luck. (shrink)

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)

In “Knowledge Under Threat” (Philosophy and Phenomenological Research 2012), Tomas Bogardus proposes a counterexample to the safety condition for knowledge. Bogardus argues that the case demonstrates that unsafe knowledge is possible. I argue that the case just corroborates the well-known requirement that modal conditions like safety must be relativized to methods of belief formation. I explore several ways of relativizing safety to belief-forming methods and I argue that none is adequate: if methods were individuated in those ways, safety would fail (...) to explain several much-discussed cases. I then propose a plausible externalist principle of method individuation. On the one hand, relativizing safety to belief-forming methods in the way suggested allows the defender of safety to account for the cases. On the other hand, it shows that the target known belief of Bogardus’s example is safe. Finally, I offer a diagnosis of a common error about the kind of cases that are typically considered potential counterexamples to the necessity of the epistemic condition: proponents of the alleged counterexamples mistake a strong condition that I call super-safety for safety. (shrink)

The main lesson from Gettier cases is that while one cannot know a proposition by luck, one can hold a lucky true belief justifiedly. Possibly because the latter is taken for granted, the relationship between epistemic justification and epistemic luck has been less discussed. The paper investigates whether luck can undermine doxastic justification, and if so, how and to what extent. It is argued that, as in the case of knowledge, beliefs can fall short of justification due to luck. Moreover, (...) it is argued that justification-undermining luck is a problem for both internalist and externalist conceptions of justification. Accordingly, it is shown that epistemic luck is a more widespread phenomenon than many in epistemology commonly assume. (shrink)

In Philosophy Without Intuitions Herman Cappelen argues that unlike what is commonly thought, contemporary analytic philosophers do not typically rely on intuitions as evidence. If they do indeed rely on intuitions, that should be evident from their written works, either explicitly in the form of ‘intuition’ talk or by means of other indicators. However, Cappelen argues, while philosophers do engage in ‘intuition’ talk, that is not a good indicator that they rely on intuitions, as ‘intuition’ and its cognates have many (...) meanings that are irrelevant to this particular question. He identifies three other indicators and argues by appeal to case studies that these indicators are not present. I argue here that an account of intuitions as intellectual seemings draws attention to intuition features that Cappelen does not consider. These intuition features appear to be regularly present in the works of contemporary analytic philosophers. (shrink)

I argue that Duncan Pritchard’s anti-luck virtue epistemology is insufficient for knowledge. I show that Pritchard fails to achieve the aim that motivates his adoption of a virtue-theoretic condition in the first place: to guarantee the appropriate direction of fit that known beliefs have. Finally, I examine whether other virtue-theoretic accounts are able to explain what I call the direction of fit problem.

What is the nature of knowledge? A popular answer to that long-standing question comes from robust virtue epistemology, whose key idea is that knowing is just a matter of succeeding cognitively—i.e., coming to believe a proposition truly—due to an exercise of cognitive ability. Versions of robust virtue epistemology further developing and systematizing this idea offer different accounts of the relation that must hold between an agent’s cognitive success and the exercise of her cognitive abilities as well as of the very (...) nature of those abilities. This paper aims to give a new robust virtue epistemological account of knowledge based on a different understanding of the nature and structure of the kind of abilities that give rise to knowledge. (shrink)

One of the most widely recognised intuitions about knowledge is that knowing precludes believing truly as a matter of luck. On Pritchard’s highly influential modal account of epistemic luck, luckily true beliefs are, roughly, those for which there are many close possible worlds in which the same belief formed in the same way is false. My aim is to introduce a new challenge to this account. Starting from the observation—as documented by a number of recent EEG studies—that our capacity to (...) detect visual stimuli fluctuates with the phase of our neural oscillations, I argue that there can be very close possible worlds in which an actual-world detectable stimulus is undetectable. However, this doesn’t diminish our willingness to attribute knowledge in the case that the stimulus is detectable, even when undetectability would result in the same belief formed in the same way being false. As I will argue at length, the modal account appears unable to accommodate this result. (shrink)

Here I explore a new line of evidence for belief–credence dualism, the thesis that beliefs and credences are distinct and equally fundamental types of mental states. Despite considerable recent disagreement over this thesis, little attention has been paid in philosophy to differences in how our mindreading systems represent the beliefs and credences of others. Fascinatingly, the systems we rely on to accurately and efficiently track others’ mental states appear to function like belief–credence dualists: Credence is tracked like an emotional state, (...) composed of both representational and affective content, whereas belief is tracked like a bare representational state with no affective component. I argue on a preliminary basis that, in this particular case, the mechanics of mentalizing likely pick out a genuine affective dimension to credence that is absent for belief, further strengthening the converging case for belief–credence dualism. (shrink)

Byrne & Hilbert (B&H) assert that reflectances embody the reality of color, but metamerism smears the authors' “real” color categories into uselessness. B&H ignore this problem, possibly because they implicitly adopt a sort of subjectivism, whereby an object is defined by the percepts (or more generally by the measurements) it engenders. Subjectivism is unwieldy, and hence prone to such troubles.

The distinction between true belief and knowledge is one of the most fundamental in philosophy, and a remarkable effort has been dedicated to formulating the conditions on which true belief constitutes knowledge. For decades, much of this epistemological undertaking has been dominated by a single strategy, referred to here as the modal approach. Shared by many of the most widely influential constraints on knowledge, including the sensitivity, safety, and anti-luck/risk conditions, this approach rests on a key underlying assumption — the (...) modal profiles available to known and unknown beliefs are in some way asymmetrical. The first aim of this paper is to deconstruct this assumption, identifying its plausibility with the way in which epistemologists frequently conceptualize human perceptual systems as excluding certain varieties of close error under conditions conducive to knowledge acquisition. The second aim of this paper is to then argue that a neural phase phenomenon indicates that this conceptualization is quite likely mistaken. This argument builds on the previous introduction of this neural phase to the context of epistemology, expanding the use of neural phase cases beyond relatively narrow questions about epistemic luck to a much more expansive critique of the modal approach as a whole.

Goldman's project of a veritistic social epistemology is based on a descriptive-success account of truth and a weak notion of knowledge as mere true belief. It is argued that, contrary to Goldman's opinion, pragmatism and social constructivism are not necessarily ruled out by the descriptive-success account of truth. Furthermore, it is shown that it appears to be questionable whether Goldman has succeeded to show that there is a weak notion of knowledge. But even if such a weak notion of knowledge (...) can be defended, this notion can result in a complete separation of knowledge from epistemic value, which does not seem to be in accordance with Goldman's concept of societal knowledge.

In this paper we survey some main arguments for and against epistemological contextualism. We distinguish and discuss various kinds of contextualism, such as attributer contextualism (the most influential version of which is semantic, conversational, or radical contextualism); indexicalism; proto-contextualism; Wittgensteinian contextualism; subject, inferential, or issue contextualism; epistemic contextualism; and virtue contextualism. Starting with a sketch of Dretske's Relevant Alternatives Theory and Nozick's Tracking Account of Knowledge, we reconstruct the history of various forms of contextualism and the ways contextualists try to (...) handle some notorious epistemological quandaries, especially skepticism and the lottery paradox. Then we outline the most important problems that contextualist theories face, and give overviews of their criticisms and defenses as developed in this issue. (shrink)

Virtue Epistemology appealingly characterizes knowledge as a kind of achievement, attributable to the exercise of cognitive virtues. But a more thorough understanding of the nature and value of achievements more broadly casts doubt on the view. In particular, it is argued that virtue epistemology’s answer to the Meno question is not as impressive as it purports to be, and that the favored analysis of ability is both problematic and irrelevant. However, considerations about achievements illuminate the best direction for the development (...) of virtue epistemology. The key, it is argued, is developing the notion of manifestation as the distinguishing feature of both knowledge and achievements. (shrink)

Epistemological contextualism has become one of the most important and widely discussed new proposals in the theory of knowledge. This special issue contributes to the debate by bringing together some of the main participants to provide a state-of-the-art discussion of the proposal. Here we offer a brief overview of the contextualist position, describe some of the main lines of criticism that have been levelled against the view, and present a summary of each of the contributions to this collection.

The main argument given for relevant alternatives theories of knowledge has been that they answer scepticism about the external world. I will argue that relevant alternatives also solve two other problems that have been much discussed in recent years, a) the bootstrapping problem and b) the apparent conflict between semantic externalism and armchair self-knowledge. Furthermore, I will argue that scepticism and Mooreanism can be embedded within the relevant alternatives framework.

SummaryThis paper addresses the question of what scientific realism implies and what it does not when it is articulated so as to provide the best defense against plausible philosophical alternatives. A summary is presented of “abductive” arguments for scientific realism, and of the epistemological and semantic conceptions upon which they depend. Taking these arguments to be the best current defense of realism, it is inquired what, in the sense just mentioned, realism implies and what it does not. It is concluded (...) that realism implies the strong rejection of epistemological foundationalism, a non‐Humean conception of causation and of explanation, and a causal rather than conceptual account of the unity of natural definitions. It is denied that realism implies bivalence or the existence of one true theory, one preferred vocabulary or one distinctly privileged science. It is further denied that realism implies that there are no unrecognized conventional aspects to scientific theorizing and it is denied that realism implies that scientists routinely do good experimental metaphysics.

While it is widely acknowledged that knowledge can be acquired via testimony, it has been argued that understanding cannot. While there is no consensus about what the epistemic relationship of understanding consists in, I argue here that regardless of how understanding is conceived there are kinds of understanding that can be acquired through testimony: easy understanding and easy-s understanding. I address a number of aspects of understanding that might stand in the way of being able to acquire understanding through testimony, (...) focusing on understanding ’s paradigmatic form and what it means to say that in order to understand something you need to “grasp” some information or the relationship between bits of information. I argue that in cases of both easy and easy-s understanding, no aspect of understanding stands in the way of it being able to acquire it through testimony. As a result, while not all understanding be acquired through testimony in all instances and for all subjects, this failure of acquisition is only a product of the complexity of the relevant information or one’s unfamiliarity with it, and not a product of the epistemic relationship of understanding.

ABSTRACTConventional wisdom holds that there is no lucky knowledge: if it is a matter of luck, in some relevant sense, that one's belief that p is true, then one does not know that p. Here I will argue that there is similarly no lucky understanding, at least in the case of one type of luck, namely environmental luck. This argument has three parts. First, we need to determine how we evaluate whether one has understanding, which requires determining what I will (...) call understanding's evaluative object. I argue that as the evaluative object of knowledge is a belief in a proposition, the evaluative object of understanding is a mental representation of a relational structure. Next, I show that arguments that environmental luck is incompatible with understanding miss the mark by considering cases in which one has a belief in a proposition is lucky to be true, instead of ones in which one's mental representation of a relational structure is lucky to obtain. I agree, then, with those who argue that one can have understanding when one's beliefs are environmentally lucky to be true, but that this compatibility is not relevant when considering the question of whether one can have environmentally lucky understanding. I then present what I take to be a properly constructed case which shows the incompatibility of environmental luck with understanding. (shrink)

I argue here for a view I call epistemic separabilism , which states that there are two different ways we can be evaluated epistemically when we assert a proposition or treat a proposition as a reason for acting: one in terms of whether we have adhered to or violated the relevant epistemic norm, and another in terms of how epistemically well-positioned we are towards the fact that we have either adhered to or violated said norm. ES has been appealed to (...) most prominently in order to explain why epistemic evaluations that conflict with the knowledge norm of assertion and practical reasoning nevertheless seem correct. Opponents of such a view are committed to what I call epistemic monism , which states that there is only one way we can be properly evaluated as epistemically appropriate asserters and practical reasoners, namely in terms of whether we have adhered to or violated the relevant norm. Accepting ES over EM has two significant consequences: first, a “metaepistemological” consequence that the structure of normative epistemic evaluations parallels that found in other normative areas , and second, that the knowledge norms of assertion and practical reasoning are no worse off than any alternatives in terms of either explanatory power or simplicity.

This paper argues that a necessary condition on inferential knowledge is that one knows all the propositions that knowledge depends on. That is, I will argue in support of a principle I call the Knowledge from Knowledge principle: (KFK) S knows that p via inference or reasoning only if S knows all the propositions on which p depends. KFK meshes well with the natural idea that (at least with respect to deductively valid or induc- tively strong arguments) the epistemic status (...) of one’s belief in the conclusion of an argument is a function of the epistemic status of the attitudes one has to the premises of that argument. One gets what one puts in: S’s belief in the conclusion C of an argument A has epistemic status E for S only if S’s belief in each of the premises C depends on also has epistemic status E.1 This is compatible, of course, with the epistemic status of S’s conclusion being greater than the epistemic status of the premises on which the conclusion of her reasoning depends. Furthermore, even though KFK applies more straightforwardly to non-suppositional inferences, we can also plausibly apply the principle to sup- positional reasoning if we treat S’s assuming for the sake of argument that p,2 as S assuming for the sake of argument that she knows that p.3 Although extremely plausible, philosophers have failed to present a concerted case in support of KFK. Most of their energy goes to articulating and/or defending some form of closure principle for knowledge.4 What is more, recently versions of this principle have been dismissed as problematic but I think without the reasons in its support been fully appreciated. This paper is an e fort to change the current state of affairs. Its focus is positive, however: my goal is to make the best case I can in support of KFK.5 To that end, the paper presents the reasons we have to accept KFK (§1), consid- ers an objection to the principle (§2), and situates the principle in the broader normative context of knowledge norms (§3).

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong, or using a method that wouldn't have given you this belief had it been false. Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist project from Carlotta Pavese (...) and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

According to the relevant alternatives theory of knowledge (RA), I know that p only if my evidence eliminates all relevant alternatives to p . Jonathan Schaffer has recently argued that David Lewis's version of RA, which is perhaps the most detailed version yet provided, cannot account for our failure to know in cases involving missed clues, that is, cases in which we see but fail to appreciate decisive evidence. I argue, however, that Lewis's version of RA survives exposure to missed (...) clue cases. Moreover, even though Schaffer maintains that Lewis's Rule of Belief provides no protection against missed clue cases, I argue that we should credit the Rule of Belief with ensuring the survival of Lewis's version of RA.

So, C. I don’t know that T. Premises 1 and 2 are both plausible. However, C seems false—I do seem to know that there is a tree before me. AI presents a puzzle because its two plausible premises yield a conclusion whose negation is plausible. And no matter whether we accept or reject AI, we find that we must give up something plausible—either premise 1, premise 2, or the negation of C. But which of these should we give up? I (...) call this question the skeptical puzzle.1 Recently, Mark Heller2 has argued that we can solve the skeptical puzzle by giving up premise 2. I argue, however, that Heller does not adequately respond to an objection to his proposed solution. I go on to argue that we can solve the skeptical puzzle by giving up premise 1. (shrink)

The sensitivity condition on knowledge says that one knows that P only if one would not believe that P if P were false. Difficulties for this condition are now well documented. Keith DeRose has recently suggested a revised sensitivity condition that is designed to avoid some of these difficulties. We argue, however, that there are decisive objections to DeRose’s revised condition. Yet rather than simply abandoning his proposed condition, we uncover a rationale for its adoption, a rationale which suggests a (...) further revision that avoids our objections as well as others. The payoff is considerable: along the way to our revision, we learn lessons about the epistemic significance of certain explanatory relations, about how we ought to envisage epistemic closure principles, and about the epistemic significance of methods of belief formation.

A central intuition many epistemologists seem to have is that knowledge is distinctively valuable. In his paper 'Radical Scepticism, Epistemic Luck and Epistemic Value', Duncan Pritchard rejects the virtue-theoretic explanation of this intuition. This explanation says that knowledge is distinctively valuable because it is a cognitive achievement. It is maintained, in the first place, that the arguments Pritchard musters against the thesis that knowledge is a cognitive achievement are unconvincing. It is argued, in the second place, that even if the (...) arguments against the thesis that knowledge is a cognitive achievement were convincing, there is another explanation of the intuition that knowledge has final value available: the question-relative treatment of knowledge.

We can address the issue of epistemic luck, the possibility that the world interferes with the activity of believing so as to keep that activity from achieving its aim, by rethinking the aim of that activity. So, if we give up truth, for example, as the aim of belief, and if we embrace a different aim—the aim of believing as my ideal self would have me believe—we can eliminate the possibility of luck and leave the world no room to interfere (...) in the affairs of the activity of believing. All this while at the same time preserving the epistemic’s responsiveness to the world. This way of seeing the epistemic is culled from the work of Kierkegaard’s pseudonyms. (shrink)

Classical philosophical analyses seek to explain knowledge as deriving from more basic notions. The influential “knowledge first” program in epistemology reverses this tradition, taking knowledge as its starting point. From the perspective of epistemic logic, however, this is not so much a reversal as it is the default—the field arguably begins with the specialization of “necessity” to “epistemic necessity”—that is, it begins with knowledge. In this context, putting knowledge second would be the reversal. This article motivates, develops, and explores such (...) a “knowledge second” approach in epistemic logic, founded on distinguishing what a body of evidence actually entails from what it is (merely) believed to entail. We import a logical framework that captures exactly this distinction, use it to define formal notions of (internal and external) justification and knowledge, and investigate applications to the KK principle, the “strong belief” postulate, and the regress problem. (shrink)

It is widely thought that if knowledge requires sensitivity, knowledge is not closed because sensitivity is not closed. This paper argues that there is no valid argument from sensitivity failure to non-closure of knowledge. Sensitivity does not imply non-closure of knowledge. Closure considerations cannot be used to adjudicate between safety and sensitivity accounts of knowledge.

This paper argues that for someone to know proposition p inferentially it is not enough that his belief in p and his justification for believing p covary with the truth of p through a sphere of possibilities. A further condition on inferential knowledge is that p's truth-maker is identical with, or causally related to, the state of affairs the justification is grounded in. This position is dubbed ‘identificationism.’.

This paper addresses the question whether introspection plus externalism about mental content warrant an a priori refutation of external-world skepticism and ontological solipsism. The suggestion is that if thought content is partly determined by affairs in the environment and if we can have non-empirical knowledge of our current thought contents, we can, just by reflection, know about the world around us -- we can know that our environment is populated with content-determining entities. After examining this type of transcendental argument and (...) discussing various objections found in the literature, I argue that the notion of privileged self-knowledge underlying this argument presupposes that we can learn, via introspection, that our so-called thoughts are propositional attitudes rather than contentless states. If, however, externalism is correct and thought content consists in the systematic dependency of internal states on relational properties, we cannot know non-empirically whether or not we have propositional attitudes. Self-knowledge (apropositional attitude) is consistent with us lacking the ability to rule out, via introspection, the possibility that we don't have any propositional attitudes. Self-knowledge provides us with knowledge of what is in our minds, but not that we have minds. Hence, the combination of externalism with the doctrine of privileged self-knowledge does not allow for an a priori refutation of skepticism and is therefore unproblematic. (shrink)

The paper makes two points. First, any theory of knowledge must explain the difference between cases of knowledge from falsehood and Gettier cases where the subject relies on reasoning from falsehood. Second, the closeness-to-the-truth approach to explaining the difference between knowledge-yielding and knowledge-suppressing falsehoods does not hold up to scrutiny.

The paper proposes a novel account of justified evidence resistance. When S inquires as to whether p is the case, S resists available counterevidence e if S either fails to countenance e or is insensitive to e’s probative force. S is justified in resisting available counterevidence e if and only if e is irrelevant.

The global method safety account of knowledge states that an agent’s true belief that p is safe and qualifies as knowledge if and only if it is formed by method M, such that her beliefs in p and her beliefs in relevantly similar propositions formed by M in all nearby worlds are true. This paper argues that global method safety is too restrictive. First, the agent may not know relevantly similar propositions via M because the belief that p is the (...) only possible outcome of M. Second, there are cases where there is a fine-grained belief that is unsafe and a relevantly similar coarse-grained belief that is safe and where both beliefs are based on the same method M. Third, the reliability of conditional reasoning, a basic belief-forming method, seems to be sensitive to fine-grained contents, as suggested by the wide variation in success rates for thematic versions of the Wason selection task.

Byrne & Hilbert defend color realism, which assumes that: (a) colors are properties of objects; (b) these objects are physical; hence, (c) colors are physical properties. I accept (a), agree that in a certain sense (b) can be defended, but reject (c). Colors are properties of perceptual objects – which also have underlying physical properties – but they are not physical properties.

On Lewis’s reading, fallibilism is the contradictory view that it is possible that S knows that p, even though S cannot eliminate some remote scenarios in which not-p. The pragmatic strategy is to make the alleged contradiction a mere pragmatic implicature, which is explained by false conversational expectations. I argue that the pragmatic strategy fails.
