Ever since Plato it has been thought that one knows only if one's belief hits the mark of truth and does so with adequate justification. The issues debated by Laurence BonJour and Ernest Sosa concern mostly the nature and conditions of such epistemic justification, and its place in our understanding of human knowledge.

My focus will be on two questions about Moore’s justification to believe the premises and the conclusion of the argument above. At stake is what makes it possible for our experiences to justify our beliefs, and what makes it possible for us to be justified in disbelieving skeptical..

Justification has long been considered a necessary condition for knowledge, and theories that deny the necessity of justification have been dismissed as nonstarters. In this chapter, we challenge this long-standing view by showing that many of the arguments offered in support of it fall short and by providing empirical evidence that individuals are often willing to attribute knowledge when epistemic justification is lacking.

This chapter is guided by the hypothesis that the point and purpose of using the concept of justification in epistemic evaluation is tied to its role in the practice of critical reflection. In section one, I propose an analysis of justification as the epistemic property in virtue of which a belief has the potential to survive ideal critical reflection. In section two, I use this analysis in arguing for a form of access internalism on which one has justification to believe (...) a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. In section three, I distinguish between propositional and doxastic versions of access internalism and argue that the propositional version avoids familiar objections to the doxastic version. In section four, I argue that the propositional version of access internalism also explains and vindicates internalist intuitions about cases. In section five, I conclude with some reflections on the relationship between critical reflection, responsibility and personhood. (shrink)

Justification logics are constructive analogues of modal logics. They are often used as epistemic logics, particularly as models of evidentialist justification. However, in this role, justification logics are defective insofar as they represent justification with a necessity-like operator, whereas actual evidentialist justification is usually probabilistic. This paper first examines and rejects extant candidates for solving this problem: Milnikel’s Logic of Uncertain Justifications, Ghari’s Hájek–Pavelka-Style Justification Logics and a version of probabilistic justification logic developed by Kokkinis et al. It then (...) proposes a new solution to the problem in the form of a justification logic that incorporates the essential features of both a fuzzy logic and a probabilistic logic. (shrink)

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

Conceptions of acceptability-based moral or political justification take it that authoritative acceptability constitutes, or contributes to, validity, or justification. There is no agreement as to what bar for authoritativeness such justification may employ. The paper engages the issue in relation to (i) the level of idealization that a bar for authoritativeness, ψ, imparts to a standard of acceptability-based justification, S, and (ii) the degree of discursive purchase of the discursive standing that S accords to people when it builds ψ. I (...) argue that (i) and (ii) are interdependent: high idealization values entail low discursive purchase, while high degrees of purchase require low idealization values. I then distinguish between alethic conceptions of justification that prioritize ends that commit to high idealization values, and recognitive conceptions that favour high discursive purchase. On this basis, I argue for a moderately recognitivist constraint on idealization. To render the recognitive discursive minimum available to relevant people at the site of justification, S should set ψ low enough so that it is a genuine option for actual people to reject relevant views in ways that S recognizes as authoritative.

Theories of emotional justification investigate the conditions under which emotions are epistemically justified or unjustified. I make three contributions to this research program. First, I show that we can generalize some familiar epistemological concepts and distinctions to emotional experiences. Second, I use these concepts and distinctions to display the limits of the ‘simple view’ of emotional justification. On this approach, the justification of emotions stems only from the contents of the mental states they are based on, also known as their (...) cognitive bases. The simple view faces the ‘gap problem’: If cognitive bases and emotions (re)present their objects and properties in different ways, then cognitive bases are not sufficient to justify emotions. Third, I offer a novel solution to the gap problem based on emotional dispositions. This solution (1) draws a line between the justification of basic and non-basic emotions, (2) preserves a broadly cognitivist view of emotions, (3) avoids a form of value skepticism that threatens inferentialist views of emotional justification, and (4) sheds new light on the structure of our epistemic access to evaluative properties.

I would like to assume that Reichenbach's distinction of Justification and Discovery lives on, and to seek arguments in his texts that would justify their relevance in this field. The persuasive force of these arguments transcends the contingent circumstances apart from which their genesis and local transmission cannot be made understandable. I shall begin by characterizing the context distinction as employed by Reichenbach in "Experience and Prediction" to differentiate between epistemology and science (1). Following Thomas Nickles and Kevin T. Kelly, (...) one can distinguish two meanings of the context distinction in Reichenbach's work. One meaning, which is primarily to be found in the earlier writings, conceives of scientific discoveries as potential objects of epistemological justification. The other meaning, typical for the later writings, removes scientific discoveries from the possible domain of epistemology. The genesis of both meanings, which demonstrates the complexity of the relationships obtaining between epistemology and science, can be made understandable by appealing to the historical context (2). Both meanings present Reichenbach with the task of establishing the autonomy of epistemology through the justification of induction. Finally, I shall expound this justification and address some of its elements of rationality characterizing philosophy of science(3). (shrink)

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we (...) express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed.

According to the bootstrapping problem, any view that allows for basic knowledge (knowledge obtained from a reliable source prior to one’s knowing that that source is reliable) is forced to accept that one can utilize a track-record argument to acquire justification for believing that one’s belief source is reliable; yet, we tend to think that acquiring justification in this way is too easy. In this paper I argue, first, that those who respond to the bootstrapping problem by denying basic knowledge (...) succumb to over-intellectualizing epistemology, and secondly, reliabilist views avoid over-intellectualization only at the expense of sanctioning bootstrapping as a benign procedure. Both of these outcomes are difficult to bear. To ward off each of these unsavory outcomes, I propose an alternative solution that draws on a distinction between two separate epistemic concepts: entitlement and justification. (shrink)

I argue that justification isn't just in the head. The argument is simple. We should be guided by our beliefs. We shouldn't be guided by anything to do what we shouldn't do. So, we shouldn't believe in ways that would guide us to do the things that we shouldn't. Among the various things we should do is discharge our duties (e.g., to fulfil our promissory obligations) and respect the rights of others (e.g., rights not to be harmed or killed by (...) agents acting on bad information). The grounds of our duties and obligations aren't just in the head. Thus, the conditions that bear on the justification of our beliefs cannot be contained wholly in our heads. The internalist might be right about aspects of normativity, but their theories tell us important normative truths without telling us the whole truth. In addition to norms that tell us how to process information, there are norms that tell us how we ought to live together. In information-asymmetry cases, these norms clearly come apart. Important normative questions about what we should do when agents (who, we might suppose, do what they subjectively ought to do) have interests that come into conflict can only be answered by externalist theories that recognise information-transcendent norms and normatively significant relations that don't supervene upon the information of any agent in particular. The internalist picture turns out to be disturbing precisely because it falls silent when we're faced with questions about how to resolve these conflicts. Resolving these conflicts should be a pressing concern for every normative theory. (shrink)

There is much to like about the idea that justification should be understood in terms of normality or normic support (Smith 2016, Goodman and Salow 2018). The view does a nice job explaining why we should think that lottery beliefs differ in justificatory status from mundane perceptual or testimonial beliefs. And it seems to do that in a way that is friendly to a broadly internalist approach to justification. In spite of its attractions, we think that the normic support view (...) faces two serious challenges. The first is that it delivers the wrong result in preface cases. These cases suggest that the view is either too sceptical or too externalist. The second is that the view struggles with certain kinds of Moorean absurdities. It turns out that these problems can easily be avoided. If we think of normality as a condition on *knowledge*, we can characterise justification in terms of its connection to knowledge and thereby avoid the difficulties discussed here. The resulting view does an equally good job explaining why we should think that our perceptual and testimonial beliefs are justified when lottery beliefs cannot be. Thus, it seems that little could be lost and much could be gained by revising the proposal and adopting a view on which it is knowledge, not justification, that depends directly upon normality.

NOTE: This paper is a reworking of some aspects of an earlier paper – ‘What else justification could be’ and also an early draft of chapter 2 of Between Probability and Certainty. I'm leaving it online as it has a couple of citations and there is some material here which didn't make it into the book (and which I may yet try to develop elsewhere). My concern in this paper is with a certain, pervasive picture of epistemic justification. On this (...) picture, acquiring justification for believing something is essentially a matter of minimising one’s risk of error – so one is justified in believing something just in case it is sufficiently likely, given one’s evidence, to be true. This view is motivated by an admittedly natural thought: If we want to be fallibilists about justification then we shouldn’t demand that something be certain – that we completely eliminate error risk – before we can be justified in believing it. But if justification does not require the complete elimination of error risk, then what could it possibly require if not its minimisation? If justification does not require epistemic certainty then what could it possibly require if not epistemic likelihood? When all is said and done, I’m not sure that I can offer satisfactory answers to these questions – but I will attempt to trace out some possible answers here. The alternative picture that I’ll outline makes use of a notion of normalcy that I take to be irreducible to notions of statistical frequency or predominance. (shrink)

According to evidentialism, a subject is justified in believing a proposition at a time, just in case their evidence on balance supports that proposition at that time. Evidentialist justification is thus a property of fit – fitting the subject’s evidence. However, evidentialism does not evaluate the subject’s evidence beyond this relation of fit. For instance, evidentialism ignores whether the subject was responsible or negligent in their inquiry. A number of objections have been raised to evidentialism involving cases of irresponsible inquiry (...) and the relevance of unpossessed evidence. In this paper, I argue that while these objections miss their mark, they do help motivate a distinct, and richer, concept of epistemic justification. This different concept of justification, what I call ‘robust justification’, supplements the evidentialist account of epistemic justification with an assessment of the subject’s evidence with respect to their inquiry. According to this proposal, to be robustly justified in believing a proposition at a time, the subject’s evidence must support that proposition at that time and that evidence must be the result of the subject’s responsible inquiry. While robust justification is not necessary for knowledge, I argue that it is an independently valuable epistemic state. (shrink)

According to the standard view, a belief is based on a reason and doxastically justified—i.e., permissibly held—only if a causal relation obtains between a reason and the belief. In this paper, I argue that a belief can be doxastically justified by a reason’s mere disposition to sustain it. Such a disposition, however, wouldn’t establish a causal connection unless it were manifested. My argument is that, in the cases I have in mind, the manifestation of this disposition would add no positive (...) epistemic feature to the belief: a belief that is justified after the manifestation of a reason’s causal powers must have already been justified before their manifestation. As a result, those who adhere to the standard causal view of the basing relation face a hard choice: they should either abandon the enormously popular view that doxastic justification has a basing requirement or modify their view of the basing relation.

A distinctive position in contemporary political philosophy is occupied by those who defend the principle of public justification. This principle states that the moral or political rules that govern our common life must be in some sense justifiable to all reasonable citizens. In this article, I evaluate Gerald Gaus’s defence of this principle, which holds that it is presupposed by our moral reactive attitudes of resentment and indignation. He argues, echoing P.F. Strawson in ‘Freedom and Resentment’, that these attitudes are (...) so deep a part of us that we are unable to rationally reject them. I examine and reject this defence of the principle. Considering the nature of our commitment to the moral reactive attitudes, I argue that those attitudes need not be grounded in a commitment to public justification. The availability of alternative grounds for these attitudes shows, contra Gaus, that we can rationally reject the principle of public justification while maintaining a wholehearted commitment to the reactive attitudes.

Justification logics are modal-like logics with the additional capability of recording the reason, or justification, for modalities in syntactic structures, called justification terms. Justification logics can be seen as explicit counterparts to modal logics. The behavior and interaction of agents in distributed system is often modeled using logics of knowledge and time. In this paper, we sketch some preliminary ideas on how the modal knowledge part of such logics of knowledge and time could be replaced with an appropriate justification logic.

An influential proposal is that knowledge involves safe belief. A belief is safe, in the relevant sense, just in case it is true in nearby metaphysically possible worlds. In this paper, I introduce a distinct but complementary notion of safety, understood in terms of epistemically possible worlds. The main aim, in doing so, is to add to the epistemologist’s tool-kit. To demonstrate the usefulness of the tool, I use it to advance and assess substantive proposals concerning knowledge and justification.

Sven Rosenkranz’s Justification as Ignorance shows how a strongly internalist conception of justification can be derived from a strongly externalist conception of knowledge, given an identification of justification with second-order ignorance and a set of structural principles concerning knowing and being in a position to know. Among these principles is an epistemic analogue of the Geach modal schema which states that one is always in a position to know that one doesn’t know p or in a position to know that (...) one doesn’t know not-p. Even suitably refined, the principle faces a range of counterexamples in which it misleadingly and persistently seems to one that one knows whether p without it seeming to one that one knows p nor that one knows not-p. These cases also threaten the book’s case for the luminosity of second-order ignorance, which is in turn central to its derivation of strongly internalist principles of justification. (shrink)

According to deontological approaches to justification, we can analyze justification in deontic terms. In this paper, I try to advance the discussion of deontological approaches by applying recent insights in the semantics of deontic modals. Specifically, I use the distinction between weak necessity modals and strong necessity modals to make progress on a question that has received surprisingly little discussion in the literature, namely: ‘What’s the best version of a deontological approach?’ The two most obvious hypotheses are the Permissive View, (...) according to which justified expresses permission, and the Obligatory View, according to which justified expresses some species of obligation. I raise difficulties for both of these hypotheses. In light of these difficulties, I propose a new position, according to which justified expresses a property I call faultlessness, defined as the dual of weak necessity modals. According to this view, an agent is justified in phi-ing iff it’s not the case that she should [/ought] not phi. I argue that this ‘Faultlessness View’ gives us precisely what’s needed to avoid the problems facing the Permissive and Obligatory Views. (shrink)

The paper challenges the view that public justification sits well with emancipatory and egalitarian intuitions. I distinguish between the depth, scope and the purchase of the discursive standing that such justification allocates, and situate within this matrix Rawls’s view of public justification. A standard objection to this view is that public justification should be more inclusive in scope. This is both plausible and problematic in emancipatory and egalitarian terms. If inclusive public justification allocates discursive standing that is rich in purchase, (...) as seems desirable in emancipatory terms, it may be unable to allocate equal standing to all relevant people. And if it is to allocate equal standing, then the equality of that standing should be construed in terms that allow for unequal discursive purchase. (shrink)

In this paper, I offer two counterexamples to the so-called ‘Uniqueness Thesis.’ As one of these examples rely on the thesis that it is possible for a justified belief to be based on an inconsistent body of evidence, I also offer reasons for this further thesis. On the assumption that doxastic justification entails propositional justification, the counterexamples seem to work.

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems diachronically irrational. To (...) avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

In his paper “There It Is” and his précis “There It Was,” Benj Hellie develops a sophisticated semantics for perceptual justification according to which perceptions in good cases can be explained by intentional psychology and can justify beliefs, whereas bad cases of perception are defective and so cannot justify beliefs. Importantly, Hellie also affords consciousness a central role in rationality insofar as only those good cases of perception within consciousness can play a justificatory function. In this commentary, I reserve judgment (...) regarding Hellie’s treatment of the rational difference between good and bad cases, but I argue there can be what he views as good cases of perceptual justification outside of consciousness.

Criminal law theory made a significant advance roughly thirty years ago when George Fletcher popularized the important conceptual distinction between justifications and excuses. In the intervening years, however, very little progress has been made in exploring the structure and function of justification defenses. The reason for this failure, I suggest, is a widely shared misconception about their place within the criminal law’s institutional structure. Contrary to what is generally believed, it is not up to trial courts to decide ex (...) post facto what conduct is justified and what is not. This determination is made ex ante by other institutional actors such as private fiduciaries, public officials, and sometimes, ordinary citizens caught in extraordinary circumstances. The court’s role is simply to review the validity of that prior exercise of decision-making discretion. More broadly, my study is intended to serve as a reminder of the importance of institutional structure in criminal law. It is almost always misleading to address issues in criminal law by way of abstract moral theorizing, as is often done, because this leaves out the crucial question of institutional division of labor. Before addressing the substantive aspect of particular questions—what conduct should be prohibited, justified, or excused—we must first address ourselves to the institutional questions that I have called the problems of authority, discretion, and legality. These institutional questions receive their most thorough treatment in two other areas of law: the private law of fiduciaries and public administrative law. If we wish to make progress in understanding justification defenses—and the institutional structure of criminal law more generally—I argue that it is to these areas of law that we should attend.

According to political liberalism, laws must be justified to all citizens in order to be legitimate. Most political liberals have taken this to mean that laws must be justified by appeal to a specific class of ‘public reasons’, which all citizens can accept. In this paper I defend an alternative, convergence, model of public justification, according to which laws can be justified to different citizens by different reasons, including reasons grounded in their comprehensive doctrines. I consider three objections to such (...) an account—that it undermines sincerity in public reason, that it underestimates the importance of shared values, and that it is insufficiently deliberative—and argue that convergence justifications are resilient to these objections. They should therefore be included within a theory of political liberalism, as a legitimate form of public justification. This has important implications for the obligations that political liberalism places upon citizens in their public deliberations and reason-giving, and might make the theory more attractive to some of its critics, particularly those sympathetic to religious belief.

In a recent article, Peter Gärdenfors (1992) has suggested that the AGM (Alchourrón, Gärdenfors, and Makinson) theory of belief revision can be given an epistemic basis by interpreting the revision postulates of that theory in terms of a version of the coherence theory of justification. To accomplish this goal Gärdenfors suggests that the AGM revision postulates concerning the conservative nature of belief revision can be interpreted in terms of a concept of epistemic entrenchment and that there are good empirical reasons (...) to adopt this view as opposed to some form of foundationalist account of the justification of our beliefs. In this paper I argue that Gärdenfors’ attempt to underwrite the AGM theory of belief revision by appealing to a form of coherentism is seriously inadequate for several reasons. (shrink)

The aim of this paper is to offer a version of the so-called conversational hypothesis of the ontogenetic connection between language and mindreading (Harris 1996, 2005; Van Cleave and Gauker 2010; Hughes et al. 2006). After arguing against a particular way of understanding the hypothesis (the communicative view), I will start from the justificatory view in philosophy of social cognition (Andrews 2012; Hutto 2004; Zawidzki 2013) to make the case for the idea that the primary function of belief and desire (...) attributions is to justify and normalize deviant patterns of behaviour. Following this framework, I elaborate upon the idea that development of folk psychological skills requires the subjects to engage in conversationally mediated joint and cooperative activities in order to acquire the conceptual capacity of ascribing propositional attitudes. After presenting the general version of the hypothesis, I present several testable sub-hypotheses and some psychological studies that give empirical plausibility to the hypothesis. (shrink)

According to some prominent accounts of scientific progress, e.g. Bird’s epistemic account, accepting new theories is progressive only if the theories are justified in the sense required for knowledge. This paper argues that epistemic justification requirements of this sort should be rejected because they misclassify many paradigmatic instances of scientific progress as non-progressive. In particular, scientific progress would be implausibly rare in cases where (a) scientists are aware that most or all previous theories in some domain have turned out to (...) be false, (b) the new theory was a result of subsuming and/or logically strengthening previous theories, or (c) scientists are aware of significant peer disagreement about which theory is correct.

The debate over the constitutional recognition of Indigenous peoples is a deeply political one. That might appear to be a controversial claim. After all, there has been much talk about minimising the scope for disagreement between ‘constitutional conservatives’ and supporters of more expansive constitutional recognition. And there is concern to ensure that any potential referendum enjoys the maximum conditions and opportunity for success. However, my argument shall be that any form of constitutional recognition of Australia’s First Peoples needs to be (...) seen as part of an ongoing transformation in the relations between Indigenous peoples and the Australian state.

Some bioethicists argue that conscientious objectors in health care should have to justify themselves, just as objectors in the military do. They should have to provide reasons that explain why they should be exempt from offering the services that they find offensive. There are two versions of this view in the literature, each giving different standards of justification. We show these views are each either too permissive (i.e. would result in problematic exemptions based on conscience) or too restrictive (i.e. would (...) produce problematic denials of exemption). We then develop a middle ground position that we believe better combines respect for the conscience of healthcare professionals with concern for the duties that they owe to patients. Our claim, in short, is that insofar as objectors should have to justify themselves, they should have to do it according to the standard that we defend rather than according to the standards that others have developed.

Preservationism is a dominant account of the justification of beliefs formed on the basis of memory. According to preservationism, a memory belief is justified only if that belief was justified when it was initially held. However, we now know that much of what we remember is not explicitly stored, but instead reconstructed when we attempt to recall it. Since reconstructive memory beliefs may not have been continuously held by the agent, or never held before at all, a purely preservationist account (...) of memory does not allow for justified reconstructed memory beliefs. In this essay, I show how a process reliabilist account can maintain preservationism about reproductive memory beliefs while accommodating the justification of reconstructive memory beliefs. I argue that reconstructive memory is an inferential process, and that therefore the beliefs it produces are justified in the same way that other inferential beliefs are justified. Accordingly, my process reliabilist account combines a preservationist account of reproductive memory with an inferential account of reconstructive memory. I end by defending this view against objections. (shrink)

The problem of skepticism is often understood as a paradox: a valid argument with plausible premises whose conclusion is that we lack justification for perceptual beliefs. Typically, this conclusion is deemed unacceptable, so a theory is offered that posits conditions for justification on which some premise is false. The theory defended here is more general, and explains why the paradox arises in the first place. Like Strawson’s (Introduction to logical theory, Wiley, New York, 1952) “ordinary language” approach to induction, the (...) theory posits something built into the very notion of justification: it is loaded with a bias towards the proposition that we are not massively deceived. Beyond the paradox, remaining skeptical problems consist of metaphysical and practical questions: whether we are massively deceived, or why we should use our loaded notion rather than some other. Such challenges have pro- found epistemological significance, but they are not problems that an a priori theory of justification can solve. (shrink)

Does epistemic justification aim at truth? The vast majority of epistemologists instinctively answer 'Yes'; it's the textbook response. Joseph Cruz and John Pollock surprisingly say no. In 'The Chimerical Appeal of Epistemic Externalism' they argue that justification bears no interesting connection to truth; justification does not even aim at truth. 'Truth is not a very interesting part of our best understanding' of justification (C&P 2004, 137); it has no 'connection to the truth.' A 'truth-aimed ... epistemology is not entitled to (...) carry the day' (C&P 2004, 138, emphasis added).Pollock and Cruz's argument for this surprising conclusion is of general interest for it is 'out of step with a very common view on the ..

Imagine two urns, each with a thousand beads - in one all the beads are blue while in the other only one of the thousand is blue. If one of these urns is pushed forward (based on the toss of a fair coin) and the single bead then randomly drawn from it is blue, we must infer that it is a thousand times more probable that the urn pushed forward is the purely blue one. The hypothesis that this was instead (...) the urn with only one blue bead would require that the occurrence of the evidence, the blue bead being drawn, was something improbable - and it is improbable that something improbable is what has occurred. Next consider an example of only one urn with no prior description. By the same reasoning as above, if all the first beads randomly drawn are blue, it is becoming more and more probable that the beads in the urn are generally blue. (Otherwise something improbable would be happening in another colour not appearing; and what’s improbable is improbable.) It is therefore probable also that the next bead drawn will be blue. This is induction. As Hume would have said, we could not know a priori, given this evidence, that the next bead will be blue. But, as he overlooked, we can know a priori, given this evidence, that it is probable that the next bead will be blue. In neither urn example has the belief regarding the beads been formed as a Humean habit of expectation after many observations of beads. (In the first case there is only one observation. The second could be modified to have all the beads drawn out at once.) Rather the belief is a product of a priori reasoning about probability. Next imagine that a coin has been tossed a thousand times and landed heads every time. There was a fair and a loaded coin. According to the same reasoning, it is overwhelmingly more probable that the coin used was the loaded one. For that the fair coin had so landed is most improbable. The hypothesis that there is no external world makes the orderliness in my current experience improbable - much like getting all heads with a fair coin. (Uncaused sensation would most probably be chaotic.) The most probable hypothesis is that of things like those we believe in causing this orderliness - as the coin’s being loaded would have caused all heads. The hypothesis that my experience has been made to take this pattern by a Cartesian malicious demon or by scientists controlling my brain in a vat can only falsely seem to make the character of the experience probable by sneaking in an inherently improbable ad hoc specification that this sort of pattern of experience was that which they were aiming at producing - like an ad hoc specification that the fair coin was one that by chance landed heads all thousand times. We may thus reject such hypotheses as improbable. So this is the problem of induction solved and scepticism answered through a priori reasoning. (shrink)

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and so (...) you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

Edmund Gettier (1963) argued that there can be justified true belief (JTB) that is not knowledge. I question the correctness of his argument by showing that Smith of Gettier’s famous examples does not earn justification for his incidentally true beliefs, while a doxastically more conscientious person S would come to hold justified but false beliefs. So, Gettier’s (and analogous) cases do not result in justified _and_ true belief. This is due to a tension between deductive closure of justification and evidential (...) support. For being justified, any believing, disbelieving, or withholding of deductively inferred propositions must be distributed proportionally to given evidential support. This proportionality principle has primacy over deductive closure in case of conflict. My argument does not save the JTB-account. But, instead of merely referring to an intuition, it explains why subjects in Gettier situations do not earn knowledge. (shrink)

A basic conviction in moral non-cognitivism is: only hypothetical norms may be justified. Hartmut Kliemt argues for a moderate variant: there are only hypothetical justifications of norms whether the norms are hypothetical or categorical in kind. In this paper the con- cept of ‘hypothetical justification’ is analyzed. It is argued that hypothetical justifications are not of the kind that we should look for in normative ethics.

In his influential book, The Nature of Morality, Gilbert Harman writes: “In explaining the observations that support a physical theory, scientists typically appeal to mathematical principles. On the other hand, one never seems to need to appeal in this way to moral principles.” What is the epistemological relevance of this contrast, if genuine? This chapter argues that ethicists and philosophers of mathematics have misunderstood it. They have confused what the chapter calls the justificatory challenge for realism about an area, D—the (...) challenge to justify our D-beliefs—with the reliability challenge for D-realism—the challenge to explain the reliability of our D-beliefs. Harman’s contrast is relevant to the first, but not, evidently, to the second. One upshot of the discussion is that genealogical debunking arguments are fallacious. Another is that indispensability considerations cannot answer the Benacerraf–Field challenge for mathematical realism. (shrink)

Kant’s arguments for the reality of human freedom and the normativity of the moral law continue to inspire work in contemporary moral philosophy. Many prominent ethicists invoke Kant, directly or indirectly, in their efforts to derive the authority of moral requirements from a more basic conception of action, agency, or rationality. But many commentators have detected a deep rift between the _Groundwork for the Metaphysics of Morals_ and the _Critique of Practical Reason_, leaving Kant’s project of justification exposed to conflicting (...) assessments and interpretations. In this major re-reading of Kant, Owen Ware defends the controversial view that Kant’s mature writings on ethics share a unified commitment to the moral law’s primacy. Using both close analysis and historical contextualization, Owen Ware overturns a paradigmatic way of reading Kant’s arguments for morality and freedom, situating them within Kant’s critical methodology at large. The result is a novel understanding of Kant that challenges much of what goes under the banner of Kantian arguments for moral normativity today. (shrink)

In Fallibilism: Evidence and Knowledge, Jessica Brown identifies a number of problems for the so-called knowledge view of justification. According to this view, we cannot justifiably believe what we do not know. Most epistemologists reject this view on the grounds that false beliefs can be justified if, say, supported by the evidence or produced by reliable processes. We think this is a mistake and that many epistemologists are classifying beliefs as justified because they have properties that indicate that something should (...) be excused. Brown thinks that previous attempts to make this case have been unsuccessful. While the difficulties Brown points to are genuine, I think they show that attempts to explain a classificatory judgment haven't been successful. Still, I would argue that the classification is correct. We need a better explanation of this classificatory judgment. I will try to clarify the justification-excuse distinction and explain why it's a mistake to insist that beliefs that violate epistemic norms might be justified. Just as it's possible for a rational agent to act without justification in spite of her best intentions, it's possible that a rational thinker who follows the evidence and meets our expectations might nevertheless believe without sufficient justification. If our justified beliefs are supposed to guide us in deciding what to do, we probably should draw on discussions from morality and the law about the justification/excuse distinction to inform our understanding of the epistemic case.

What justifies our beliefs about what other people say? According to epistemic inferentialism​, the justification of comprehension-based beliefs depends on the justification of other beliefs, e.g., beliefs about what words the speaker uttered or even what sounds they produced. According to epistemic non-inferentialism, the justification of comprehension-based beliefs ​does not depend on the justification of other beliefs. This paper offers a new defense of epistemic non-inferentialism. First, I discuss three counterexamples to epistemic non-inferentialism provided recently by Brendan Balcerak Jackson. I (...) argue that only one of Balcerak Jackson’s counterexamples is effective, and that it is effective against only one version of epistemic non-inferentialism, viz. language comprehension dogmatism. Second, I propose an alternative version of epistemic non-inferentialism, viz. comprehension-process reliabilism, which is immune to these counterexamples. I conclude that we should follow Balcerak Jackson in his rejection of language comprehension dogmatism but not all the way to the endorsement of epistemic inferentialism. Comprehension-process reliabilism is superior to both these alternatives. (shrink)

It is widely accepted that in fallible reasoning potential error necessarily increases with every additional step, whether inferences or premises, because it grows in the same way that the probability of a lengthening conjunction shrinks. As it stands, this is disappointing but, I will argue, not out of keeping with our experience. However, consulting an expert, proof-checking, constructing gap-free proofs, and gathering more evidence for a given conclusion also add more steps, and we think these actions have the potential to (...) improve our reliability or justifiedness. Thus, the received wisdom about the growth of error implies a skepticism about the possibility of improving our reliability and level of justification through effort. Paradoxically, and even more implausibly, taking steps to decrease your potential error necessarily increases it. I will argue that the self-help steps listed here are of a distinctive type, involving composition rather than conjunction. Error grows differently over composition than over conjunction, I argue, and this dissolves the apparent paradox. (shrink)

According to a captivating picture, epistemic justification is essentially a matter of epistemic or evidential likelihood. While certain problems for this view are well known, it is motivated by a very natural thought—if justification can fall short of epistemic certainty, then what else could it possibly be? In this paper I shall develop an alternative way of thinking about epistemic justification. On this conception, the difference between justification and likelihood turns out to be akin to the more widely recognised difference (...) between ceteris paribus laws and brute statistical generalisations. I go on to discuss, in light of this suggestion, issues such as classical and lottery-driven scepticism as well as the lottery and preface paradoxes. (shrink)

Say that two goals are normatively coincident just in case one cannot aim for one goal without automatically aiming for the other. While knowledge and justification are distinct epistemic goals, with distinct achievement conditions, this paper begins from the suggestion that they are nevertheless normatively coincident—aiming for knowledge and aiming for justification are one and the same activity. A number of surprising consequences follow from this—both specific consequences about how we can ascribe knowledge and justification in lottery cases and more (...) general consequences about the nature of justification and the relationship between justification and evidential probability. Many of these consequences turn out to be at variance with conventional, prevailing views. (shrink)

In recent years there has been a resurgence of interest among epistemologists in the nature of understanding, with some authors arguing that understanding should replace knowledge as the primary focus of epistemology. But what is understanding? According to what is often called the standard view, understanding is a species of knowledge. Although this view has recently been challenged in various ways, even the critics of the standard view have assumed that understanding requires justification and belief. I argue that it requires (...) neither. If sound, these arguments have important upshots not only for the nature of understanding, but also for its distinctive epistemic value and its role in contemporary epistemology. (shrink)

Turri argues against what he calls an “orthodox” view of the relationship between propositional and doxastic justification, according to which (Basis) it is sufficient for S to be doxastically justified in believing p that p is propositionally justified for S in virtue of having reason(s) R and S believes p on the basis of R. According to Turri, (Basis) is false and hence the orthodox view is wrong. Turri offers “an alternative proposal,” the definitive thesis of which is that the (...) subject’s intellectual abilities explain why a given proposition, p, is justified for her, and argues that, contra the orthodoxy, this proposal leads to explaining propositional justification in terms of doxastic justification rather than vice versa. In this paper, I argue for the following claims: (i) There are good reasons to think that Turri misidentifies “the orthodox view” and his objection thereby misfires, (ii) Even if we assume that Turri’s identification of the orthodox view is correct, his counter-examples to that view are far from being decisive, and (iii) Turri’s own proposal is not “an alternative” to the orthodox view but can be accommodated by it.
