My goal in this paper is to show that naturalists cannot reasonably endorse moral realism. My argument will come in two parts. The first part aims to show that any plausible and naturalistically acceptable argument in favor of belief in objective moral properties will appeal in part to simplicity considerations (broadly construed)—and this regardless of whether moral properties are reducible to non-moral properties. The second part argues for the conclusion that appeals to simplicity justify belief in moral properties only if (...) either those properties are not objective or something like theism is true. Thus, if my argument is sound, naturalists can reasonably accept moral realism only if they are prepared to accept something like theism. But, as will become clear, naturalists can reasonably accept theism or something like it only if belief in some such doctrine is justified by the methods of science. For present purposes, I’ll assume (what I think virtually every naturalist will grant) that belief in theism and relevantly similar doctrines is not justified by the methods of science. Thus, I will conclude that naturalists cannot reasonably accept moral realism. (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)

Adams offers a theistically-based framework for ethics, based upon the idea of a transcendent, infinite good, which is God, and its relation to the many finite examples of good in our experience. His account shows how philosophically unfashionable religious concepts can enrich ethical thought. "...one of the two most important books in moral philosophy of the last quarter century, the other being After Virtue."--Theology Today.

What are the philosophical views of contemporary professional philosophers? We surveyed many professional philosophers in order to help determine their views on 30 central philosophical issues. This article documents the results. It also reveals correlations among philosophical views and between these views and factors such as age, gender, and nationality. A factor analysis suggests that an individual's views on these issues factor into a few underlying components that predict much of the variation in those views. The results of a metasurvey (...) also suggest that many of the results of the survey are surprising: philosophers as a whole have quite inaccurate beliefs about the distribution of philosophical views in the profession.

Human beings can have “strongly certain” beliefs—indubitable, veridical beliefs with a unique phenomenology—about necessarily true propositions like 2+2=4. On the plausible assumption that mathematical entities are platonic abstracta, naturalist theories fail to provide an adequate causal explanation for such beliefs because they cannot show how the propositional content of the causally inert abstracta can figure in a chain of physical causes. Theories which explain such beliefs as “corresponding” to the abstracta, but without any causal relationship, entail impossibilities. God, or a (...) very god-like being, provides the best causal explanation for such beliefs. (shrink)

Renowned scholar Robert Adams explores the relation between religion and ethics through a comprehensive philosophical account of a theistically-based framework for ethics. Adams' framework begins with the good rather than the right, and with excellence rather than usefulness. He argues that loving the excellent, of which adoring God is a clear example, is the most fundamental aspect of a life well lived. Developing his original and detailed theory, Adams contends that devotion, the sacred, grace, martyrdom, worship, vocation, faith, and other (...) concepts drawn from religious ethics have been sorely overlooked in moral philosophy and can enrich the texture of ethical thought.

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)

Gilbert Harman and Judith Thomson have argued that moral facts cannot explain our moral beliefs, claiming that such facts could not play a causal role in the formation of those beliefs. This paper shows these arguments to be misguided, for they would require that we abandon any number of intuitively plausible explanations in non-moral contexts as well. But abandoning the causal strand in the argument over moral explanations does not spell immediate victory for the moral realist, since it must still (...) be shown that moral facts do figure in our best global explanatory theory.

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)

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)

Discussion of moral explanation has reached an impasse, with proponents of contemporary ethical naturalism upholding the explanatory integrity of moral facts and properties, and opponents--including both antirealists and non-naturalistic realists--insisting that such robustly explanatory pretensions as moral theory has be explained away. I propose that the key to solving the problem lies in the question whether instances of moral properties are causally efficacious. It is argued that, given the truth of contemporary ethical naturalism, moral properties are causally efficacious if the (...) properties of the special sciences are. (shrink)

Many of the arguments for and against robust moral realism parallel arguments for and against theism. In this article, I consider one of the shared challenges: the explanatory challenge. The article begins with a presentation of Harman's formulation of the explanatory challenge as applied to moral realism and theism. I then examine two responses offered by robust moral realists to the explanatory challenge, one by Russ Shafer-Landau and another by David Enoch. Shafer-Landau argues that the moral realist can plausibly respond (...) to the challenge in a way unavailable to theists. I argue that Shafer-Landau's response is implausible as it stands and that once revised, it will apply to theism just as well. I then argue that Enoch's response, to the extent that it is plausible, can be used to defend theism as well. (shrink)

Do moral properties figure in the best explanatory account of the world? According to a popular realist argument, if they do, then they earn their ontological rights, for only properties that figure in the best explanation of experience are real properties. Although this realist strategy has been widely influential—not just in metaethics, but also in philosophy of mind and philosophy of science—no one has actually made the case that moral realism requires: namely, that moral facts really will figure in the (...) best explanatory picture of the world. This issue may have been neglected in part because the influential dialectic on moral explanations between philosophers Gilbert Harman and Nicholas Sturgeon has focused debate on whether moral facts figure in relevant explanations. Yet as others have noted, explanatory relevance is irrelevant when it comes to realism: after all, according to the popular realist argument, it is inference to the best explanation of experience that is supposed to confer ontological rights. I propose to ask, then, the relevant question about moral explanations: should we think that moral properties will figure in the best explanatory account of the world? (shrink)

This essay presents a moral argument for the rationality of theistic belief. If all I have to go on morally are my own moral intuitions and reasoning and those of others, I am rationally led to skepticism, both about the possibility of moral knowledge and about my moral effectiveness. This skepticism is extensive, amounting to moral despair. But such despair cannot be rational. It follows that the assumption of the argument must be false and I must be able to rely (...) on more than my own human powers and those of others in attempting to live a moral life. The Christian God has such a function. Hence, if it is rational to attempt a moral life, it is rational to believe in the Christian God. (shrink)

The relationship between God and morality has been a topic of philosophical discussion since Socrates engaged Euthyphro in the agora. In recent years, it has received a lot of attention, as theistic philosophers have attempted to show that divine command theory and other theistic meta‐ethical accounts are defensible. Whether metaphysical naturalism is compatible with moral realism is a related (and equally controversial) topic. This essay surveys the main issues in these debates.
