Many take the claim that you cannot ‘get’ an ‘ought’ from an ‘is’ to imply that non- moral beliefs are by themselves incapable of justifying moral beliefs. I argue that this is a mistake and that the position that moral beliefs are justified exclusively by non-moral beliefs—a view that I call moral inferentialism—presents an attractive non-sceptical moral epistemology.

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.

Do the facts of evolution generate an epistemic challenge to moral realism? Some think so, and many “evolutionary debunking arguments” have been discussed in the recent literature. But they are all murky right where it counts most: exactly which epistemic principle is meant to take us from evolutionary considerations to the skeptical conclusion? Here, I will identify several distinct species of evolutionary debunking argument in the literature, each one of which relies on a distinct epistemic principle. Drawing on recent work (...) in epistemology, I will show that most of these initially plausible principles are false, spoiling the arguments that rely on them. And we will see that each argument threatens only one popular view of moral psychology: a “Representationalist” view on which our moral judgments rely crucially on a mental intermediary—e.g. a sentiment, gut reaction, or affect-laden intuition—delivered by our evolved moral faculty. In the end, only one evolutionary debunking argument remains a menace: an “ Argument from Symmetry ” that I will introduce to the literature. But we will see that it should worry only all naturalists, pressuring them into a trilemma: give up moral realism, accept a rationalism that is incongruous with naturalism, or give up naturalism. Non-naturalists are free and clear. (shrink)

In this paper, I hope to solve a problem that’s as old as the hills: the problem of contingency for religious belief. Paradigmatic examples of this argument begin with a counterfactual premise: had we been born at a different time or in a difference place, we easily could have held different beliefs on religious topics. Ultimately, and perhaps by additional steps, we’re meant to reach the skeptical conclusion that very many of our religious beliefs do not amount to knowledge. I (...) survey some historical examples of this argument, and I try to fill the gap between the counterfactual premise and the skeptical conclusion as forcefully as possible. I consider the following possibilities: there are no additional steps in the argument; or there are and they concern the alleged safety condition on knowledge, or the alleged non-accidentality condition on knowledge, or the unclarity produced by disagreement. On every possibility, the argument from the counterfactual premise to the conclusion of widespread skepticism is invalid. It seems, then, that there is no serious problem of contingency for religious belief. (shrink)

Can we have objective knowledge of right and wrong, of how we should live and what there is reason to do? Can it be anything but luck when our moral beliefs are true? Kieran Setiya confronts these questions in their most compelling and articulate forms, and argues that if there is objective ethical knowledge, human nature is its source.

It can easily look like evolution is in a better position to explain the reliability of our perceptual beliefs than the reliability of our moral beliefs. This paper takes a closer look at the issue and argues that there’s no reason—no reason which armchair philosophers could uncover—to think evolution can better explain perceptual reliability than moral reliability. It also offers a diagnosis of why it seemed otherwise. The diagnosis concerns our need to use the truth predicate as a generalizing logical (...) device in the perceptual case but not in the moral case. (shrink)

In this paper, we present what we call the argument from accidental truth, according to which some instances of deflationist schemata, even those carefully reformulated and adjusted by Field and Horwich to accommodate the truth of utterances, are falsified due to accidental truths. Since the folk concept of truth allows for accidental truths, the deflationary theory of truth will face a serious problem. In particular, it follows that the deflationist schema fails to capture the proper extension of truth by precluding (...) accidental truths of utterances. Even though the argument uses the contextualist cases, this conclusion does not require so much as the truth of contextualism, but only two assumptions, the existence of context-relative non-literal contents of utterances (or speech acts), and the existence of accidental truths, both of which are widely accepted by folks and theorists. We will also consider various responses to the argument, including the revisionary deflationist position, all of which we argue are unsatisfactory or committed to a highly implausible view. (shrink)

In this essay, I distinguish two different epistemological strategies an anti-realist might pursue in developing an "evolutionary debunking" of moral realism. Then I argue that a moral realist can resist both of these strategies by calling into question the epistemological presuppositions on which they rest. Nonetheless, I conclude that these arguments point to a legitimate source of dissatisfaction about many forms of moral realism. I conclude by discussing the way forward that these conclusions indicate.

The Reliability Challenge to moral non-naturalism has received substantial attention recently in the literature on moral epistemology. While the popularity of this particular challenge is a recent development, the challenge has a long history, as the form of this challenge can be traced back to a skeptical challenge in the philosophy of mathematics raised by Paul Benacerraf. The current Reliability Challenge is widely regarded as the most sophisticated way to develop this skeptical line of thinking, making the Reliability Challenge the (...) strongest epistemic challenge to normative nonnaturalism. In this paper, I argue that the innovations that have occurred since Benacerraf’s statement of the challenge are misconceived and confused in a number of ways. The Reliability Challenge is not the most potent epistemic challenge to moral non-naturalism. The most potent challenge comes from the fact that there is a causal condition on knowledge – or, more precisely, a becaual condition – that non-natural moral facts cannot satisfy. (shrink)

Denying the conclusion of a valid argument is not generally permissible if one suspends on one premise of the argument and believes the other premise. This can happen when one’s only critique of an argument is to undermine one premise. There is incoherence there. Here I examine how this is relevant to the debate on evolutionary debunking of our moral knowledge. I argue that one significant line of response to the debunker is unsuccessful: merely undermining the debunker’s empirical claim. It (...) is not rational to respond this way and believe one has moral knowledge. First I present evidence that prominent critics of the debunking argument merely undermine the debunker’s empirical claim. Then I argue for two premises: merely undermining a premise can only justify a middling amount of doubt towards the premise and we should have no more doubt about the conclusion of a valid argument than we do about the premises. Implications of the argument are explored. (shrink)

Several anti-debunkers have argued that evolutionary explanations of our moral beliefs fail to meet a necessary condition on undermining defeat called modal security. They conclude that evolution, therefore, does not debunk our moral beliefs. This article shows that modal security is false if knowledge is virtuous achievement. New information can undermine a given belief without providing reason to doubt that that belief is sensitive or safe. This leads to a novel conception of undermining defeat, and it shows that successful debunking (...) of moral realism is possible. (shrink)

What is it to have conclusive reasons to believe a proposition P? According to a view famously defended by Dretske, a reason R is conclusive for P just in case [R would not be the case unless P were the case]. I argue that, while knowing that P is plausibly related to having conclusive reasons to believe that P, having such reasons cannot be understood in terms of the truth of this counterfactual condition. Simple examples show that it is possible (...) to believe P on the basis of reasons that satisfy the counterfactual, and still get things right about P only as a matter of luck. Seeing where this account of conclusive reasons goes wrong points to an important distinction between having conclusive reasons and relying on reasons that are in point of fact conclusive. It also has wider consequences for whether modal principles like sensitivity and safety can rule out the pernicious kind of epistemic luck, or the kind of luck that interferes with knowledge.

The gist of modal epistemology is expressed in the idea that you fail to know if you do believe truly but it is seriously possible for you to believe falsely. According to subjunctivism, this idea is captured by certain subjunctive conditionals. One formulation invokes a safety condition—“If S had believed P, then P would have been the case,” while the other invokes a sensitivity condition—“If P had been false, S would not have believed that P.” According to simple subjunctivism, such (...) conditionals do not contrapose and Sosa derives important epistemological consequences which favor safety from this difference. However, simple subjunctivism is inadequate. I return to Goodman and his analysis of factuals and propose modal stability, which is restricted sensitivity or enhanced safety as a proper epistemic condition for the non-accidental connection between the basis for the belief and the relevant facts of the matter. The idea of modal stability combines robustness (benefi ts of safety) with responsiveness to facts (benefi ts of sensitivity) and recovers the original motivation for the relevant alternatives theory—when testing for claims of knowledge that p we ask what might be the case if not-p, but we ignore irrelevant possibilities. Epistemic modal conditions should be expressed in terms of conditionals of connection which contrapose within the limits of relevance. (shrink)

Peter Baumann develops and defends a distinctive version of epistemic contextualism, the view that the truth conditions or the meaning of knowledge attributions of the form "S knows that p" can vary with the context of the attributor. The first part of the book examines arguments for contextualism and develops Baumann's version. It begins by dealing with the argument from cases and ordinary usage, and then addresses "theoretical" arguments, from reliability and from luck. The second part of the book discusses (...) the problems contextualism faces, to which it must respond, and provides an extension of contextualism beyond epistemology. The third part of the book is focused on some major objections to contextualism and alternative views, namely subject-sensitive invariantism, contrastivism and relativism. (shrink)

Based on the discussion of a novel version of the Barn County scenario, the paper argues for a new explication of knowledge undermining luck. In passing, an as yet undetected form of benign luck is identified.

Current epistemological orthodoxy has it that knowledge is incompatible with luck. More precisely: Knowledge is incompatible with epistemic luck . This is often treated as a truism which is not even in need of argumentative support. In this paper, I argue that there is lucky knowledge. In the first part, I use an intuitive and not very developed notion of luck to show that there are cases of knowledge which are “lucky” in that sense. In the second part, I look (...) at philosophical conceptions of luck and come to the conclusion that knowledge can be lucky in those senses, too. I also turns out that a probabilistic notion of luck can help us see in what ways a particular piece of knowledge or belief can be lucky or not lucky. (shrink)

Argues that there are two distinct senses in which knowledge is incompatible with accidental truth - each of which can be traced to a distinct role played by everyday knowledge attributions.

In the first, shorter part of the paper I point out some problems and potential misunderstandings connected with B. Berčić’s treatment of Nozick’s sensitivity condition for knowledge. In the second part of the paper I offer the condition of modal stability or limited sensitivity as a revision of Nozickian conditions for non-accidental connection between our belief and the truth of our belief. “When it is seriously possible for you to falsely believe that p,” that is a good reason for denying (...) that you know that p. Sensitivity within limits requires that we consider more possible worlds than classical sensitivity, but not the worlds outside this sphere. The idea of modal stability combines robustness with responsiveness to facts. (shrink)
