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)

Christopher Cowie has recently argued that companions in guilt arguments against the moral error theory that appeal to epistemic reasons cannot work. I show that such companions in guilt arguments can work if, as we have good reason to believe, moral reasons and epistemic reasons are instances of fundamentally the same relation.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no one knows that they (...) do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

John Mackie's stimulating book is a complete and clear treatise on moral theory. His writings on normative ethics-the moral principles he recommends-offer a fresh approach on a much neglected subject, and the work as a whole is undoubtedly a major contribution to modern philosophy.The author deals first with the status of ethics, arguing that there are not objective values, that morality cannot be discovered but must be made. He examines next the content of ethics, seeing morality as a functional device, (...) basically the same at all times but changing significantly in response to changes in the human condition. He sketches a practical moral system, criticizing but also borrowing from both utilitarian and absolutist views. Thirdly, the frontiers of ethics, areas of contact with psychology, metaphysics, theology, law and politcs, are explored.Throughout, his aim is to discuss a wide range of questions that are both philosophical and practical, working within a distinctive version of subjectivism-an "error" theory of the apparent objectivity of values. John Mackie has drawn on the contributions of such classic thinkers as Plato, Aristotle, Hobbes, Hume, Kant and Sidgwick, and on more recent discussions, to produce a thought-provoking account that will inspire both the general reader and the student of philosophy.

Moral realism of a paradigmatic sort -- Defending the parallel -- The parity premise -- Epistemic nihilism -- Epistemic expressivism : traditional views -- Epistemic expressivism : nontraditional views -- Epistemic reductionism -- Three objections to the core argument.

Moral error theories are often rejected by appeal to ‘companions in guilt’ arguments. The most popular form of companions in guilt argument takes epistemic reasons for belief as a ‘companion’ and proceeds by analogy. I show that this strategy fails. I claim that the companions in guilt theorist must understand epistemic reasons as evidential support relations if her argument is to be dialectically effective. I then present a dilemma. Either epistemic reasons are evidential support relations or they are not. If (...) they are not, then the companions in guilt argument fails. If they are, then a reduction of epistemic reasons to evidential support relations becomes available and, consequently, epistemic reasons cease to be a viable ‘companion’ for moral reasons. I recommend this structure of argument over existing strategies within the literature and defend my claims against recent objections from companions in guilt theorists. (shrink)

Many philosophers hold antirealist views about morality, according to which moral facts or truths do not exist. Does this imply that other types of normative facts, such as epistemic facts, do not exist? The Normative Web develops a positive answer to this question. By means of an analogy between moral and epistemic facts, Terence Cuneo presents a compelling defence of robust realism in ethics. In so doing, he engages with a range of antirealist positions in epistemology such as error theories, (...) expressivist views, and reductionist views of epistemic reasons. (shrink)

A ‘companions in guilt’ strategy against moral error theory aims to show that the latter proves too much: if sound, it supports an implausible error-theoretic conclusion in other areas such as epistemic or practical reasoning. Christopher Cowie [2016 Cowie, C. 2016. Good News for Moral Error Theorists: A Master Argument Against Companions in Guilt Strategies, Australasian Journal of Philosophy 94/1: 115–30.[Taylor & Francis Online], [Web of Science ®] [Google Scholar]] has recently produced what he claims is a ‘master argument’ against (...) all such strategies. The essence of his argument is that CG arguments cannot work because they are afflicted by internal incoherence or inconsistency. I argue, first, that Cowie's master argument does not succeed. Beyond this, I argue that there is no good reason to think that any such argument—one that purports to identify an internal incoherence in CG arguments—can succeed. Second, I argue that the main substantive area of disagreement between error theorists and CG theorists essentially concerns the conceptual profile of epistemic reasons—specifically, whether they are strongly categorical—not the ontological question of whether such reasons exist. I then develop an argument in favour of the CG theorist's position by considering the moral error theorist's arguments in support of the conceptual claim that moral reasons are strongly categorical. These include, notably, criticisms made by Joyce [2011] and Olson [2014] of Finlay's [2008] ‘end relational’ view of morality, according to which moral reasons are relative to some end or standard, hence not strongly categorical. Examining these criticisms, I argue that, based on what moral error theorists have said regarding the conceptual profile of moral reasons, there is a strong case to be made that moral reasons are strongly categorical if and only if epistemic reasons are.

One recently popular strategy for avoiding the moral error theory is via a ‘companions in guilt’ argument. I focus on those recently popular arguments that take epistemic facts as a companion in guilt for moral facts. I claim that there is an internal tension between the two main premises of these arguments. It is a consequence of this that either the soundness or the dialectical force of the companions in guilt argument is undermined. I defend this claim via (i) analogy (...) with philosophical debates concerning the indispensability of mathematical objects to natural science, and (ii) discussion of the ‘entanglement’ of epistemic concepts and moral concepts in deliberation. I conclude by proposing a positive view of what kind of argument must be used if moral error theories are to be successfully undermined. (shrink)

: Radical meta-normative skepticism is the view that no standard, norm, or principle has objective authority or normative force. It does not deny that there are norms, standards of correctness, and principles of various kinds that render it possible that we succeed or fail in measuring up to their prerogatives. Rather, it denies that any norm has the status of commanding with objective authority, of giving rise to normative reasons to take seriously and follow its demands. Two powerful transcendental arguments (...) challenge this view. First, skepticism is said to be self-defeating: Settling what to accept, and in particular whether to accept skepticism, appears to be a reason-guided enterprise. How can skeptics coherently support their view by citing reasons in their favor after they just rejected them throughout? Second, there is the practical-deliberative version, most recently developed by David Enoch: We are essentially deliberative creatures. Yet deliberation appears to require that there are correct answers in the form of normative reasons to our practical questions. Thus confidence in the sensible nature of deliberation should inspire confidence in reasons. The essay undermines both transcendental arguments by demonstrating, first, how to support skepticism without deserting its tenets, and, second, how to deliberate in skeptical fashion. (shrink)
