Buchanan and Powell hope to rescue optimism about moral perfectibility from the ’received view’ of human evolution, by tweaking our view of the innate character of morality. I argue that their intervention is hampered by an unnecessary commitment to nativism, by gender bias within the received view, and by liberal presuppositions.

Evolutionary debunking arguments appeal to selective etiologies of human morality in an attempt to undermine moral realism. But is morality actually the product of evolution by natural selection? Although debunking arguments have attracted considerable attention in recent years, little of it has been devoted to whether the underlying evolutionary assumptions are credible. In this paper, we take a closer look at the evolutionary hypotheses put forward by two leading debunkers, namely Sharon Street and Richard Joyce. We raise a battery of (...) considerations, both empirical and theoretical, that combine to cast doubt on the plausibility of both hypotheses. We also suggest that it is unlikely that there is in the vicinity a plausible alternative hypothesis suitable for the debunker’s cause. (shrink)

Non-skeptical robust realists about normativity, mathematics, or any other domain of non- causal truths are committed to a correlation between their beliefs and non- causal, mind-independent facts. Hartry Field and others have argued that if realists cannot explain this striking correlation, that is a strong reason to reject their theory. Some consider this argument, known as the Benacerraf–Field argument, as the strongest challenge to robust realism about mathematics, normativity, and even logic. In this article I offer two closely related accounts (...) for the type of explanation needed in order to address Field's challenge. I then argue that both accounts imply that the striking correlation to which robust realists are committed is explainable, thereby discharging Field's challenge. Finally, I respond to some objections and end with a few unresolved worries. (shrink)

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow (...) from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking--staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms--if it is, as Joyce writes, "just something that helped our ancestors make more babies"--might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality. (shrink)

In the wake of the paleobiological revolution of the 1970s and 1980s, paleontologists continue to investigate far-reaching questions about how evolution works. Many of those questions have a philosophical dimension. How is macroevolution related to evolutionary changes within populations? Is evolutionary history contingent? How much can we know about the causes of evolutionary trends? How do paleontologists read the patterns in the fossil record to learn about the underlying evolutionary processes? Derek Turner explores these and other questions, introducing the reader (...) to exciting recent work in the philosophy of paleontology and to theoretical issues including punctuated equilibria and species selection. He also critically examines some of the major accomplishments and arguments of paleontologists of the last 40 years. (shrink)

David Enoch develops, argues for, and defends a strongly realist and objectivist view of ethics and normativity more broadly. This view--according to which there are perfectly objective, universal, moral and other normative truths that are not in any way reducible to other, natural truths--is familiar, but this book is the first in-detail development of the positive motivations for the view into reasonably precise arguments. And when the book turns to defend Robust Realism against traditional objections, it mobilizes the original positive (...) arguments for the view to help with fending off the objections. (shrink)

What implications, if any, does evolutionary biology have for metaethics? Many believe that our evolutionary background supports a deflationary metaethics, providing a basis at least for debunking ethical realism. Some arguments for this conclusion appeal to claims about the etiology of the mental capacities we employ in ethical judgment, while others appeal to the etiology of the content of our moral beliefs. In both cases the debunkers’ claim is that the causal roles played by evolutionary factors raise deep epistemic problems (...) for realism: if ethical truths are objective or independent of our evaluative attitudes, as realists maintain, then we lose our justification for our ethical beliefs once we become aware of the evolutionary shaping of our ethical capacities or beliefs, which would not have disposed us reliably to track independent ethical truths; realism, they claim, thus saddles us with ethical skepticism. I distinguish and spell out various evolutionary debunking arguments along these lines and argue that they all fail: the capacity etiology argument fails to raise any special or serious problem for realism, and the content etiology arguments all rely on strong explanatory claims about our moral beliefs that are simply not supported by the science unless it is supplemented by philosophical claims that just beg the question against realism from the start. While the various debunking arguments do bring out some interesting commitments of ethical realism, and even raise some good challenges as realists develop positive moral epistemologies, they fall far short of their debunking ambitions.

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

Humans are unique in the animal world in the extent to which their day-to-day behavior is governed by a complex set of rules and principles commonly called norms. Norms delimit the bounds of proper behavior in a host of domains, providing an invisible web of normative structure embracing virtually all aspects of social life. People also find many norms to be deeply meaningful. Norms give rise to powerful subjective feelings that, in the view of many, are an important part of (...) what it is to be a human agent. Despite the vital role of norms in human lives and human behavior, and the central role they play in explanations in the social sciences, there has been very little systematic attention devoted to norms in cognitive science. Much existing research is partial and piecemeal, making it difficult to know how individual findings cohere into a comprehensive picture. Our goal in this essay is to offer an account of the psychological mechanisms and processes underlying norms that integrates what is known and can serve as a framework for future research. (shrink)

We think of logic as objective. We also think that we are reliable about logic. These views jointly generate a puzzle: How is it that we are reliable about logic? How is it that our logical beliefs match an objective domain of logical fact? This is an instance of a more general challenge to explain our reliability about a priori domains. In this paper, I argue that the nature of this challenge has not been properly understood. I explicate the challenge (...) both in general and for the particular case of logic. I also argue that two seemingly attractive responses – appealing to a faculty of rational insight or to the nature of concept possession – are incapable of answering the challenge. (shrink)

Sentimental Rules is an ambitious and highly interdisciplinary work, which proposes and defends a new theory about the nature and evolution of moral judgment. In it, philosopher Shaun Nichols develops the theory that emotions play a critical role in both the psychological and the cultural underpinnings of basic moral judgment. Nichols argues that our norms prohibiting the harming of others are fundamentally associated with our emotional responses to those harms, and that such 'sentimental rules' enjoy an advantage in cultural evolution, (...) which partly explains the success of certain moral norms. This has sweeping and exciting implications for philosophical ethics. Nichols builds on an explosion of recent intriguing experimental work in psychology on our capacity for moral judgment and shows how this empirical work has broad import for enduring philosophical problems. The result is an account that illuminates fundamental questions about the character of moral emotions and the role of sentiment and reason in how we make our moral judgments. This work should appeal widely across philosophy and the other disciplines that comprise cognitive science. (shrink)

Richard Swinburne presents a substantially rewritten and updated edition of his most celebrated book. No other work has made a more powerful case for the probability of the existence of God. Swinburne gives a rigorous and penetrating analysis of the most important arguments for theism: the cosmological argument; arguments from the existence of laws of nature and the 'fine-tuning' of the universe; from the occurrence of consciousness and moral awareness; and from miracles and religious experience. He claims that while none (...) of these arguments are deductively valid, they do give inductive support to theism and that, even when the argument from evil is weighed against them, taken together they offer good grounds to support the probability that there is a God. The overall structure of the discussion and its conclusion have been retained for this new edition, but much has been changed in order to strengthen the argumentation and to take account of Swinburne's subsequent work on the nature of consciousness and the problem of evil, and of the latest philosophical and scientific writing, especially in respect of the laws of nature and the argument from fine-tuning. This is now the definitive version of a classic in the philosophy of religion. (shrink)

Metaethical—or, more generally, metanormative— realism faces a serious epistemological challenge. Realists owe us—very roughly speaking—an account of how it is that we can have epistemic access to the normative truths about which they are realists. This much is, it seems, uncontroversial among metaethicists, myself included. But this is as far as the agreement goes, for it is not clear—nor uncontroversial—how best to understand the challenge, what the best realist way of coping with it is, and how successful this attempt is. (...) In this paper I try, first, to present the challenge in its strongest version, and second, to show how realists—indeed, robust realists—can cope with it. The strongest version of the challenge is, I argue, that of explaining the correlation between our normative beliefs and the independent normative truths. And I suggest an evolutionary explanation as a way of solving it. (shrink)

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 this paper, I explore one of the most important but least discussed components of an evidentialist case for or against theism: its intrinsic plausibility and simplicity as a theory aside from the evidence. This is a crucial consideration in any inductive framework, whether Inference to the Best Explanation, probabilism, or another. In the context of Bayesian reasoning, this corresponds to an assessment of theism's intrinsic probability. I offer a survey of how philosophers of science have attempted to evaluate the (...) intrinsic plausibility and simplicity of scientific theories more generally, before applying these considerations to the question of God's existence.

What are the epistemological implications of the cognitive science of religion (CSR)? The lion’s share of discussion fixates on whether CSR undermines (or debunks or explains away) theistic belief. But could the field offer positive support for theism? If so, how? That is our question. Our answer takes the form of an evidential argument for theism from standard models and research in the field. According to CSR, we are naturally disposed to believe in supernatural agents and these beliefs are constrained (...) in certain ways. The three main theories of this supernatural disposition are byproduct theories, adaptationist theories, and hybrid theories. We argue that our supernatural disposition—as understood by any of the main theories—is more surprising and improbable given naturalism than theism and thus serves as evidence for theism over naturalism.

There are several important arguments in metaethics that rely on explanatory considerations. Gilbert Harman has presented a challenge to the existence of moral facts that depends on the claim that the best explanation of our moral beliefs does not involve moral facts. The Reliability Challenge against moral realism depends on the claim that moral realism is incompatible with there being a satisfying explanation of our reliability about moral truths. The purpose of this chapter is to examine these and related arguments. (...) In particular, this chapter will discuss four kinds of arguments – Harman’s Challenge, evolutionary debunking arguments, irrelevant influence arguments, and the Reliability Challenge – understood as arguments against moral realism. The main goals of this chapter are (i) to articulate the strongest version of these arguments; (ii) to present and assess the central epistemological principles underlying these arguments; and (iii) to determine what a realist would have to do to adequately respond to these arguments.

Evolutionary debunking arguments, notably Sharon Street’s Darwinian Dilemma (2006), allege that moral realists need to explain the reliability of our moral judgments, given their evolutionary sources. David Copp (2008) and David Enoch (2010) take up the challenge. I argue on empirical grounds that realists have not met the challenge and moreover cannot do so. The outcome is that there are empirically-motivated reasons for thinking moral realists cannot explain moral reliability, given our current empirical understanding.

This paper presents a survey of the literature on the problem of contingency in science. The survey is structured around three challenges faced by current attempts at understanding the conflict between “contingentist” and “inevitabilist” interpretations of scientific knowledge and practice. First, the challenge of definition: it proves hard to define the positions that are at stake in a way that is both conceptually rigorous and does justice to the plethora of views on the issue. Second, the challenge of distinction: some (...) features of the debate suggest that the contingency issue may not be sufficiently distinct from other philosophical debates to constitute a genuine, independent philosophical problem. And third, the challenge of decidability: it remains unclear whether and how the conflict could be settled on the basis of empirical evidence from the actual history of science. The paper argues that in order to make progress in the present debate, we need to distinguish more systematically between different expressions that claims about contingency and inevitability in science can take. To this end, it introduces a taxonomy of different contingency and inevitability claims. The taxonomy has the structure of an ordered quadruple. Each contingency and each inevitability claim contains an answer to the following four questions: (how) are alternatives to current science possible, what types of alternatives are we talking about, how should the alternatives be assessed, and how different are they from actual science?

This paper reconstructs what I take to be the central evolutionary debunking argument that underlies recent critiques of moral realism. The argument claims that given the extent of evolutionary influence on our moral faculties, and assuming the truth of moral realism, it would be a massive coincidence were our moral faculties reliable ones. Given this coincidence, any presumptive warrant enjoyed by our moral beliefs is defeated. So if moral realism is true, then we can have no warranted moral beliefs, and (...) hence no moral knowledge. In response, I first develop what is perhaps the most natural reply on behalf of realism namely, that many of our highly presumptively warranted moral beliefs are immune to evolutionary influence and so can be used to assess and eventually resuscitate the epistemic merits of those that have been subject to such influence. I then identify five distinct ways in which the charge of massive coincidence has been understood and defended. I argue that each interpretation is subject to serious worries. If I am right, these putative defeaters are themselves subject to defeat. Thus many of our moral beliefs continue to be highly warranted, even if moral realism is true. (shrink)

Instead of conceiving ethical commands as divine revelations or as the discoveries of brilliant thinkers, we should see our ethical practices as evolving over tens of thousands of years, as members of our species have worked out how to live together and prosper. Here, Kitcher elaborates his radical vision of this millennia-long ethical project.

Steven Pinker has said that one of the most important questions humans can ask of themselves is whether moral progress has occurred or is likely to occur. Buchanan and Powell here address that question, in order to provide the first naturalistic, empirically-informed and analytically sophisticated theory of moral progress--explaining the capacities in the human brain that allow for it, the role of the environment, and how contingent and fragile moral progress can be.

Reductionist forms of moral realism, such as naturalist realism, are often thought immune to epistemological objections that have been raised against nonnaturalist realism in the form of reliability worries or evolutionary debunking arguments. This article establishes that reductionist realist views can only explain the reliability of our moral beliefs at the cost of incurring repugnant first-order conclusions.

Is the science of moral cognition usefully modelled on aspects of Universal Grammar? Are human beings born with an innate 'moral grammar' that causes them to analyse human action in terms of its moral structure, with just as little awareness as they analyse human speech in terms of its grammatical structure? Questions like these have been at the forefront of moral psychology ever since John Mikhail revived them in his influential work on the linguistic analogy and its implications for jurisprudence (...) and moral theory. In this seminal book, Mikhail offers a careful and sustained analysis of the moral grammar hypothesis, showing how some of John Rawls' original ideas about the linguistic analogy, together with famous thought experiments like the trolley problem, can be used to improve our understanding of moral and legal judgement.
