In this paper, we develop an account of the justification thinkers have for employing certain basic belief-forming methods. The guiding idea is inspired by Reichenbach's work on induction. There are certain projects in which thinkers are rationally required to engage. Thinkers are epistemically justified in employing any belief-forming method such that "if it doesn't work, nothing will" for successfully engaging in such a project. We present a detailed account based on this intuitive thought and address objections to it. We conclude (...) by commenting on the implications that our account may have for other important epistemological issues and debates. (shrink)

I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that thedemand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair (...) or question-begging one.

Contemporary realist theories of value claim to be compatible with natural science. In this paper, I call this claim into question by arguing that Darwinian considerations pose a dilemma for these theories. The main thrust of my argument is this. Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes. The challenge for realist theories of value is to explain the relation between these evolutionary influences on our evaluative attitudes, on the one hand, and the (...) independent evaluative truths that realism posits, on the other. Realism, I argue, can give no satisfactory account of this relation. On the one hand, the realist may claim that there is no relation between evolutionary influences on our evaluative attitudes and independent evaluative truths. But this claim leads to the implausible skeptical result that most of our evaluative judgements are off track due to the distorting pressure of Darwinian forces. The realist’s other option is to claim that there is a relation between evolutionary influences and independent evaluative truths, namely that natural selection favored ancestors who were able to grasp those truths. But this account, I argue, is unacceptable on scientific grounds. Either way, then, realist theories of value prove unable to accommodate the fact that Darwinian forces have deeply influenced the content of human values. After responding to three objections, the third of which leads me to argue against a realist understanding of the disvalue of pain, I conclude by sketching how antirealism is able to sidestep the dilemma I have presented. Antirealist theories of value are able to offer an alternative account of the relation between evolutionary forces and evaluative facts —
an account that allows us to reconcile our understanding of evaluative truth with our understanding of the many non-rational causes that have played a role in shaping our evaluative judgements. (shrink)

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)

I argue that certain species of belief, such as mathematical, logical, and normative beliefs, are insulated from a form of Harman-style debunking argument whereas moral beliefs, the primary target of such arguments, are not. Harman-style arguments have been misunderstood as attempts to directly undermine our moral beliefs. They are rather best given as burden-shifting arguments, concluding that we need additional reasons to maintain our moral beliefs. If we understand them this way, then we can see why moral beliefs are vulnerable (...) to such arguments while mathematical, logical, and normative beliefs are not—the very construction of Harman-style skeptical arguments requires the truth of significant fragments of our mathematical, logical, and normative beliefs, but requires no such thing of our moral beliefs. Given this property, Harman-style skeptical arguments against logical, mathematical, and normative beliefs are self-effacing; doubting these beliefs on the basis of such arguments results in the loss of our reasons for doubt. But we can cleanly doubt the truth of morality. (shrink)

It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content? (shrink)

According to phenomenal conservatism, seemings can provide prima facie justification for beliefs. In order to fully assess phenomenal conservatism, it is important to understand the nature of seemings. Two views are that (SG) seemings are a sui generis propositional attitude, and that (D2B) seemings are nothing over and above dispositions to believe. Proponents of (SG) reject (D2B) in large part by providing four distinct objections against (D2B). First, seemings have a distinctive phenomenology, but dispositions to believe do not. Second, seemings (...) can provide a non-trivial explanation for dispositions to believe, which wouldn’t be possible if seemings were dispositions to believe. Third, there are some dispositions to believe that are not seemings. Fourth, there are instances of seemings which are not dispositions to believe. I consider and reject each of these objections. The first and third objections rely on a misunderstanding of (D2B). The second objection fails because there are contexts in which an appeal to a previously unknown identity can provide an interesting explanation. The fourth objection overlooks the possibility of finkish and masked dispositions, phenomena which are widely accepted in the dispositions literature. I conclude that (D2B) escapes these common objections unscathed. (shrink)

There are striking parallels, largely unexplored in the literature, between skeptical arguments against theism and against moral realism. After sketching four arguments meant to do this double duty, I restrict my attention to an explanatory argument that claims that we have most reason to deny the existence of moral facts (and so, by extrapolation, theistic ones), because such putative facts have no causal-explanatory power. I reject the proposed parity, and offer reasons to think that the potential vulnerabilities of moral realism (...) on this front are quite different from those of the theist. Key Words: causal power • explanatory power • Gilbert Harman • moral facts • moral realism • theism. (shrink)

Many of us care about the existence of ethical facts because they appear crucial to making sense of our practical lives. On one tempting line of thought, this idea can also play a central role in justifying our belief in those facts. David Enoch has developed this thought into a formidable new proposal in moral epistemology: that the deliberative indispensability of ethical facts gives us epistemic justification for believing in such facts. This chapter argues that Enoch’s proposal fails because it (...) conflicts with a central fact about epistemic justification: that the norms of epistemic justification have the content that they do in part because of some positive connection between those norms and the truth of the beliefs that these norms govern. Alternatives to Enoch’s attempt to defend the idea that deliberative indispensability confers epistemic justification fail for parallel reasons. The chapter concludes that deliberative indispensability does not provide epistemic justification. (shrink)

At the beginning of Book X of his last work The Laws Plato turns his attention from violent and outrageous actions in general to the particular case of undisciplined and presumptuous behaviour in matters of religion: “We have already stated summarily what the punishment should be for temple-robbing, whether by open force or secretly. But the punishments for the various sorts of insolence in speech or action with regard to the gods, which a man can show in word or deed, (...) have to be proclaimed after we have provided an exordium. Let this be it: ‘No one believing, as the laws prescribe, in the existence of the gods has ever yet performed an impious action willingly, or uttered a lawless word. Anyone acting in such a way is in one of three conditions: either, first, he does not believe the proposition aforesaid; or, second, he believes that though the gods exist they have no concern about men; or, third, he believes that they can easily be won over by the bribery of prayer and sacrifice”.

-/- Some phenomena within nature exhibit such exquisiteness of structure, function or interconnectedness that many people have found it natural—if not inescapable—to see a deliberative and directive mind behind those phenomena. The mind in question, being prior to nature itself, is typically taken to be supernatural. Philosophically inclined thinkers have both historically and at present labored to shape the relevant intuition into a more formal, logically rigorous inference. The resultant theistic arguments, in their various logical forms, share a focus on (...) plan, purpose, intention and design, and are thus classified as teleological arguments (or, frequently, as arguments from or to design). -/- Although enjoying some prominent defenders over the centuries, such arguments have also attracted serious criticisms from a number of major historical and contemporary thinkers. Both critics and advocates are found not only among philosophers, but come from scientific and other disciplines as well. In the following discussion, major variant forms of teleological arguments will be distinguished and explored, traditional philosophical and other criticisms will be discussed, and the most prominent contemporary turns (cosmic fine tuning arguments, many-worlds theories, and the present Intelligent Design debate) will be tracked. Discussion will conclude with a brief look at one historically important non-inferential approach to the issue. (shrink)

Two of the most prominent evolutionary debunking arguments are Sharon Street's Darwinian Dilemma for Normative Realism and Alvin Plantinga's Evolutionary Argument against Atheism. In the former, Street appeals to evolutionary considerations to debunk normative realism. In the latter, Plantinga appeals to similar considerations to debunk atheism. By a careful comparison of these two arguments, I develop a new strategy to help normative realists resist Street's debunking attempt. In her Darwinian Dilemma, Street makes epistemological commitments that ultimately support Plantinga's structurally similar (...) argument. If Street succeeds in debunking normative realism, I argue, then she also succeeds in debunking atheism. But atheism is a suppressed premise of the Darwinian Dilemma as well as a commitment of almost all normative anti-realists. If Street's argument entails theism, then the Darwinian Dilemma is internally incoherent and should be abandoned by almost everyone. (shrink)

I examine the two main arguments that Richard Dawkins offers in The God Delusion to convince believers that God does not exist. Dawkins’ arguments, as stated, are not successful. Neither do sympathetic extensive reformulations have what it takes to require a believer to admit that God probably does not exist. I further argue against Dawkins’ assuming that belief in God, if legitimate, can be only a scientific hypothesis.

While acknowledging the importance of sophisticated reformulations of some of the traditional arguments for “natural and revealed” religion, the bulk of this chapter expounds and then compares and contrasts the other two main developments over the past half century in the epistemology of religious belief: Wittgensteinian philosophy of religion, and Reformed epistemology. What unites these two movements is that both insist that religious belief does not typically have its origin in the attempt to explain things, both insist that religious belief (...) typically consists of a more or less comprehensive perspective on reality rather than consisting of beliefs about God simply added on to one’s other beliefs, and both insist that religious belief does not have to be rationally grounded in order to be acceptable. What especially differentiates the two movements is the difference of their polemical partners—Enlightenment evidentialism for the Reformed epistemologists versus logical positivism for Wittgenstein—and the fact that the Reformed epistemologists are resolutely realist concerning God whereas most of the Wittgensteinians are apparently not theistic realists. In closing, I point out important similarities between some remarks of early Heidegger and the shared positions of the Wittgensteinians and the Reformed epistemologists. (shrink)

This essay addresses two popular worries about morality in an atheistic context. The first is a psychological or sociological one: the worry that unbelief makes one more disposed to act immorally than one would be if one had theistic beliefs and, consequently, widespread atheism produces societal dysfunction. This essay argues that the relationship between atheism and human moral beliefs and behaviour is complex, and that highly secularized societies can also be deeply moral societies. The second worry is philosophical in nature: (...) the worry that if there is no God or gods, then there are also no objective moral truths or facts. This essay make the case that the question of whether there are objective moral truths is independent of the existence or nonexistence of God. In the final section, the essay discusses the nature and possible grounds of objective morality in an atheistic context. (shrink)
