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.

I start by arguing that Mackie’s claim that there are no objective values is a nonsensical one. I do this by ‘assembling reminders’ of the correct use of the term ‘values’ and by examining the grammar of moral propositions à la Wittgenstein. I also examine Hare’s thought experiment which is used to demonstrate “that no real issue can be built around the objectivity or otherwise of moral values” before briefly looking at Mackie’s ‘argument from queerness’. In the final (...) section I propose that Robert Arrington’s ‘conceptual relativism’, inspired by Wittgenstein, helps to make our use of moral language more perspicuous and avoids the problems faced by Mackie.

J. L. Mackie famously argued that a commitment to non-existent objective values permeates ordinary moral thought and discourse. According to a standard interpretation, Mackie construed this commitment as a universal and indeed essential feature of moral judgments. In this paper I argue that we should rather ascribe to Mackie a form of semantic pluralism, according to which not all moral judgments involve the commitment to objective values. This interpretation not only makes better sense of what Mackie (...) actually says, but also renders his error theory immune to a powerful objection. (shrink)

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.

Moral error theory of the kind defended by J. L. Mackie and Richard Joyce is premised on two claims: (1) that moral judgements essentially presuppose that moral value has absolute authority, and (2) that this presupposition is false, because nothing has absolute authority. This paper accepts (2) but rejects (1). It is argued first that (1) is not the best explanation of the evidence from moral practice, and second that even if it were, the error (...) class='Hi'>theory would still be mistaken, because the assumption does not contaminate the meaning or truth-conditions of moral claims. These are determined by the essential application conditions for moral concepts, which are relational rather than absolute. An analogy is drawn between moral judgements and motion judgements. (shrink)

Moral error theories claim that (i) moral utterances express moral beliefs, that (ii) moral beliefs ascribe moral properties, and that (iii) moral properties are not instantiated. Thus, according to these views, there seems to be conclusive evidence against the truth of our ordinary moral beliefs. Furthermore, many error theorists claim that, even if we accepted moral error theory, we could still in principle keep our first-order moral beliefs. This chapter argues that this last claim makes many (...) popular versions of the moral error theory incompatible with the standard philosophical accounts of beliefs. Functionalism, normative theories of beliefs, representationalism, and interpretationalism all entail that being sensitive to thoughts about evidence is a constitutive feature of beliefs. Given that many moral error theorists deny that moral beliefs have this quality, their views are in a direct conflict with the most popular views about the nature of beliefs. (shrink)

My aim in this essay is largely defensive. I aim to discuss some problems for moral error theory and to offer plausible solutions. A full positive defense of moral error theory would require substantial investigations of rival metaethical views, but that is beyond the scope of this essay. I will, however, try to motivate moral error theory and to clarify its commitments. Moral error theorists typically accept two claims – one conceptual and one (...) ontological – about moral facts. The conceptual claim is that moral facts are or entail facts about categorical reasons (and correspondingly that moral claims are or entail claims about categorical reasons); the ontological claim is that there are no categorical reasons – and consequently no moral facts – in reality. I accept this version of moral error theory and I try to unpack what it amounts to in Section 2.1 In the course of doing so I consider two preliminary objections: that moral error theory is (probably) false because its implications are intuitively unacceptable (what I call the Moorean objection) and that the general motivation for moral error theory is self-undermining in that it rests on a hidden appeal to norms. The above characterization seems to entail the standard formulation of moral error theory, according to which first-order moral claims are uniformly false. Critics have argued that the standard formulation is incoherent since – by the law of excluded middle – the negation of a false claim is true. Hence if ‘Torture is wrong’ is false, ‘Torture is not wrong’ is true. Contrary to what moral error theorists contend, then, moral error theory seems to carry first-order moral implications that by the theory’s own lights are uniformly false. In Section 3 I suggest a formulation that is consistent with the standard formulation of moral error theory, free of first-order moral implications, and subject to no logical difficulties. In Section 4 I consider and rebut Stephen Finlay’s recent attack on moral error theory. According to Finlay the conceptual claim is false because all moral claims – and indeed all normative claims – are, or should be understood as, relativized to some moral standard or system of ends. Moral error theorists thus attribute to ordinary speakers an error that simply isn’t there. I argue that Finlay’s view has some very implausible implications and that it does not avoid commitment to various forms of error theory. This becomes especially clear when we focus on fundamental moral claims. In Section 5 I consider the worry that error theorists’ rejection of categorical reasons proves too much; in particular, the worry that error theorists’ qualms about categorical reasons apply equally to claims about hypothetical reasons, that is, claims to the effect that there is reason to take the means to one’s ends. In my view error theorists such as Mackie and Joyce have failed to pay due consideration to this problem. What the challenge establishes, I submit, is that error theorists cannot just take for granted that hypothetical reasons are metaphysically unproblematic; they must offer an account of hypothetical reasons that shows that they are. I argue that the only plausible account available to error theorists is one according to which claims about hypothetical reasons reduce to non-normative claims about relations between means and ends.

This article provides of review of the book A World without Values: Essays on John Mackie's Moral Error Theory, edited by Richard Joyce and Simon Kirchin.

What kind of properties are moral qualities, such as rightness, badness, etc? Some ethicists doubt that there are any such properties; they maintain that thinking that something is morally wrong (for example) is comparable to thinking that something is a unicorn or a ghost. These "moral error theorists" argue that the world simply does not contain the kind of properties or objects necessary to render our moral judgments true. This radical form of moral skepticism was championed by the philosopher (...) John Mackie (1917-1981). This anthology is a collection of philosophical essays critically examining Mackie’s view. (shrink)

John P. Burgess has remarked that Mackie: “even though he talks of the need to invent morality … does not seem to think that this proposal could be worked into a revisionary meta-ethic”. In the first part of my paper, I argue that Mackie did propose a revisionary meta-ethic (conceptual reformism), and that Mackie was not a preservatist, abolitionist, or semantic pluralist. I also argue that interpreting Mackie as a conceptual reformist enables us to overcome a (...) number of standard objections to his error theory. The upshot is that we should take seriously the idea that Mackie was a conceptual reform moral error theorist. (shrink)

To hold an error theory about morality is to endorse a kind of radical moral skepticism—a skepticism analogous to atheism in the religious domain. The atheist thinks that religious utterances, such as “God loves you,” really are truth-evaluable assertions (as opposed to being veiled commands or expressions of hope, etc.), but that the world just doesn’t contain the items (e.g., God) necessary to render such assertions true. Similarly, the moral error theorist maintains that moral judgments are truth-evaluable (...) assertions (thus contrasting with the noncognitivist), but that the world doesn’t contain the properties (e.g., moral goodness, evil, moral obligation) needed to render moral judgments true. In other words, moral discourse aims at the truth but systematically fails to secure it. If there is no such property as moral wrongness, for example, then no judgment of the form “X is morally wrong” will be true (where “X” denotes an actual action or state of affairs). Advocates of this position include Hinckfuss 1987; Joyce 2001; Mackie 1977 (see MACKIE, J. L.). Various forms of moral skepticism—some of which are arguably instances of the error theoretic stance—have been familiar to philosophers since ancient times. (See SKEPTICISM, MORAL.) Error theoretic views can be controversial—as in the case of religion and morality—or widely agreed upon—as in the case of ghosts and phlogiston. It is important to note that error theorists maintain that the judgments in question are erroneous not merely because of the absence of any objective moral facts sufficient to render them true, but also because of the absence of any non-objective moral facts sufficient to render them true. There is, for example, a kind of moral realist who maintains that moral properties are objective features of the universe (see REALISM, MORAL). There is also a family of metaethical views according to which moral properties are in some manner constituted by us—by our beliefs, attitudes, practices, etc.. (shrink)

_ Source: _Volume 13, Issue 4, pp 397 - 402 Moral error theorists and moral realists agree about several disputed metaethical issues. They typically agree that ordinary moral judgments are beliefs and that ordinary moral utterances purport to refer to moral facts. But they disagree on the crucial ontological question of whether there are any moral facts. Moral error theorists hold that there are not and that, as a consequence, ordinary moral beliefs are systematically mistaken and ordinary moral (...) judgments uniformly untrue. Perhaps because of its kinship with moral realism, moral error theory is often considered the most notorious of moral scepticisms. While the view has been widely discussed, it has had relatively few defenders. _Moral Error Theory: History, Critique, Defence_ examines the view from a historical as well as a contemporary perspective, and purports to respond to some of its most prominent challenges. This précis is a brief summary of the book’s content. (shrink)

Mackie's argument for the Error Theory is described. Four ways of responding to Mackie's argument—the Instrumental Approach, the Universalization Approach, the Reasons Approach, and the Constitutivist Approach—are outlined and evaluated. It emerges that though the Constitutivist Approach offers the most promising response to Mackie's argument, it is difficult to say whether that response is adequate or not.

Error theorists argue that there is a fundamental mistake, an error of some kind, at the heart of commonsense morality. They have drawn on evolutionary theory to support some of their claims. This article looks at four different models of evolution and assesses what implications can be drawn from them concerning commonsense morality and the claims of the error theorists Mackie, Ruse and Joyce. The author first spells out the main points of error (...) class='Hi'>theory, then discusses how recent proponents of error theory have attempted to join error theory about ethics with an evolutionary perspective. Finally, to assess their claims, the author examines what the models of evolution put forward by Darwin, Dawkins, Gould and Haught imply about error theory in ethics. (shrink)

In 1910–11 Axel Hägerström introduced an emotive theory of ethics asserting moral propositions and valuations in general to be neither true nor false. However, it is less well known that he modified his theory in the following year, now making a distinction between what he called primary and secondary valuations. From 1912 onwards, he restricted his emotive theory to primary valuations only, and applied an error theory to secondary ones. According to Hägerström, secondary valuations state (...) that objects have special value properties, that we believe we become acquainted with in primary valuations. But, in fact, we do not have any such acquaintance. There are no, and cannot be any such, properties in objects. What we take to be a property is a projection of a feeling. Therefore, all secondary valuations are false. In 1917 he developed his theory further and distinguished between different types of secondary valuations with different structures. Yet he argued that they all are false. Hägerström's discussion is interesting because, among other reasons, it is historically a very early version of error theory in ethics. In a way it can also be said to be a precursor to later versions, e.g., John Mackie's (1946 and 1977). There are obvious resemblances between their accounts. Mackie's discussion is, of course, independent of Hägerström's. (shrink)

This dissertation explores arguments and questions related to moral error theory – the idea that morality inevitably involves a fundamental and serious error such that moral judgments and statements never come out true. It is suggested that the truth of error theory remains a non-negligible possibility, and that we for this reason should take a version of moral fictionalism seriously. I begin by defining error theory as the claim that moral judgments are beliefs (...) with moral propositions as content, moral utterances are assertions of moral propositions, and no positive moral proposition is true. Second, after giving an account of J.L. Mackie’s error theory, I argue that neither Richard Joyce’s nor Jonas Olson’s argument for error theory gives us strong reasons to believe it. According to Joyce, moral discourse presupposes non-institutional desire-transcendent reasons and non-institutional categorical requirements. I challenge this claim by arguing that morality can be understood as an institution, and that the assumption that there are non-institutional moral reasons and requirements can be understood as entering pragmatically into moral conversations. According to Olson, moral discourse involves a commitment to irreducibly normative favoring relations between facts and actions. I challenge this claim by challenging Olson’s response to Stephen Finlay’s argument against absolutist accounts of moral discourse. Third, I discuss two objections to error theory, and argue that neither gives us strong reasons to reject it. According to the first objection, which is suggested by Terence Cuneo, error theory entails epistemic error theory, which has problematic consequences. After indicating some possible responses on part of the epistemic error theorist, I challenge the entailment claim by defending Hilary Kornblith’s account of epistemic reasons as hypothetical reasons. According to the second objection, error theory entails normative error theory, which cannot be believed. Although he does not defend this objection, Bart Streumer has given an argument for the unbelievability claim. I challenge Streumer’s argument by suggesting that we might have hypothetical reasons to believe normative error theory and that, properly understood, Streumer’s conclusion is not as radical as it may first appear. Fourth, I discuss what practical implications the discovery that error theory is true would have for first-order moral thinking and discourse. I argue that if this practice is overall non-morally valuable to us, we ought to revise engagement in it on the model of role-playing in live action role-playing games if we find out that error theory is true. Some have claimed that Richard Joyce’s fictionalism encounters problems. I argue that by incorporating the suggestion that engagement in revised moral practice is modeled on role-playing, fictionalism can escape these problems and preserve the benefits of first-order moral practice.

Over-time variability characterizes not only individual-level emotions, but also group-level emotions, those that occur when people identify with social groups and appraise events in terms of their implications for those groups. We discuss theory and research regarding the role of emotions in intergroup contexts, focusing on their dynamic nature. We then describe new insights into the causes and consequences of emotional dynamics that flow from conceptualizing emotions as based in group membership, and conclude with research recommendations.

I highlight a tension within the moral error theoretic stance. Although I do not show that it is fatal, I believe the tension is problematic. In stating the tension I outline a conception of the common moral background against which it arises. I also discuss aspects of the similar error theories developed by John Mackie and Richard Joyce in order to show the tension at work.

In ‘Animalism versus Lockeanism: a Current Controversy’, The Philosophical Quarterly, 48 (1998), pp. 302–18, Harold Noonan examined the relation between animalist and neo‐Lockean theories of personal identity. As well as presenting arguments intended to support a modest compatibilism of animalism and neo‐Lockeanism, he advanced a new proposal about the relation between persons and human beings which was intended to evade the principal animalist objections to neo‐Lockean theories. I argue both that the arguments for compatibilism are without force, and that Noonan’s (...) new neo‐Lockean proposal is inadequate. (shrink)

Mackie outlines Locke's representationalist theory. He analyses the relation between representationalism and the picture theory of ideas. The theory's relation to the veil of perception doctrine is also critically examined. Mackie criticizes the verificationist theory of meaning and instead argues that ideas should be understood as intentional objects. Mackie introduces and defends a version of realism, which he calls ‘common‐sense realism’.

Annotation In this book Mr. Mackie selects for critical discussion six related topic which are prominent in John Locke's Essay concerning Human Understanding: ...

Mackie examines the distinction between primary and secondary qualities. It is argued that Locke's distinction supports the claim that he held a representative theory of perception. Mackie discussed Locke's arguments for the distinction. The relation of Locke's account to Molyneaux's problem is considered. Mackie critically compares his reformulation of the primary/secondary distinction with that of Jonathan Bennett.

In this chapter, Mackie presents a defence of Locke against Berkeley's attack on abstraction. It is argued that Locke's theory of ideas primarily concerns our ability to employ words and statements. Locke's theory concerning ideas of numbers is criticized. Three theories of universals are considered: realism, nominalism, and conceptualism; it is concluded, however, that the notion of there being distinct things with which we connect general words with particular things is mistaken. Mackie instead proposes a (...) class='Hi'>theory of general words being ‘annexed’ to features of things. (shrink)

Mackie sets out Locke's general theory of identity and raises some difficulties with the account. Hume's claim that the notion of identity is a fiction is critically assessed. Mackie argues that there is a relation between Locke's notion of identity and the notion that individuals can have essences. He presents an argument for what he calls Locke's thesis about the relativity of identity. The relevance of Kripke's discussion of identity and named individuals is examined. It is argued (...) that Locke's thesis about the relativity of identity can provide a means of understanding some problems concerning identity through time. (shrink)

Mackie attempts to revise Locke's theory of the identity of persons. Locke's equation of personal identity with the unity of consciousness is set out. Mackie examines various objections to Locke's theory and his use of puzzle cases is highlighted. Recent theories of personal identity, such as Parfit's, are critically discussed. Mackie suggests that the equation of personal identity with the continuity of neurophysiological structure would resolve some of the difficulties associated with an account of personal (...) identity. (shrink)

This chapter considers both Locke's theory of substance and Berkeley's subsequent criticisms of it. Mackie discusses the difference between real essence and nominal essence. He argues that Locke should have equated substance with real essence and rejected the notion of substance as substratum. Mackie also argues that Locke invokes a theory of the use of language that anticipates the theory of natural kinds put forward by Kripke.

A novel treatment of an issue central to much current work in metaphysics: the distinction between the essential and accidental properties of individuals. Mackie challenges widely held views, and arrives at what she calls "minimalist essentialism," an unorthodox theory according to which ordinary individuals have relatively few interesting essential properties. Mackie's clear and accessible discussions of issues surrounding necessity and essentialism mean that the book will appeal as much to graduate students as it will to seasoned metaphysicians.

I discuss a thesis that I call ‘The Appearance of Mind-Independence’, to the effect that, to the subject of an ordinary perceptual experience, it seems that the experience involves the awareness of a mind-independent world. Although this thesis appears to be very widely accepted, I argue that it is open to serious challenge. Whether such a challenge can be maintained is especially relevant to the assessment of any theory, such as Berkeley’s idealism, according to which the only objects of (...) which we are aware in perception are mind-dependent. But the issue is of significance for the philosophy of perception more generally. In the course of my sceptical discussion, I argue that recent work by Campbell and Cassam may be flawed by a failure to take sufficiently seriously the requirements for genuine mind-independence.

In this book, J. L. Mackie makes a careful study of several philosophical issues involved in his account of causation. Mackie follows Hume's distinction between causation as a concept and causation as it is ‘in the objects’ and attempts to provide an account of both aspects. Mackie examines the treatment of causation by philosophers such as Hume, Kant, Mill, Russell, Ducasse, Kneale, Hart and Honore, and von Wright. Mackie's own account involves an analysis of causal statements (...) in terms of counterfactual conditionals though these are judged to be incapable of giving a complete account of causation. Mackie argues that regularity theory too can only offer an incomplete picture of the nature of causation. In the course of his analysis, Mackie critically examines the account of causation offered by Kant, as well as the contemporary Kantian approaches offered by philosophers such as Bennett and Strawson. Also addressed are issues such as the direction of causation, the relation of statistical laws and functional laws, the role of causal statements in legal contexts, and the understanding of causes both as ‘facts’ and ‘events’. Throughout the discussion of these topics, Mackie develops his own complex account of the nature of causation, finally bringing his analysis to bear in regard to the topic of teleology and the question of whether final causes can be justifiably reduced to efficient causes.

Derek Parfit claims that “Williams and Mackie…do not use the normative concepts that I and other Non-Naturalists use.” Whatever we think of Parfit’s interpretation of Williams, his interpretation of Mackie should be rejected. For understandable historical reasons, Mackie’s texts are ambiguous. But if we apply to the interpretation of Mackie the same principle of charity Parfit employs in interpreting Williams, we find decisive reason to interpret Mackie as using the same normative concepts as Non-Naturalists.

Discussion is frequently observed in democratic politics, but change in view is rarely observed. Call this the ‘unchanging minds hypothesis’. I assume that a given belief or desire is not isolated, but, rather, is located in a network structure of attitudes, such that persuasion sufficient to change an attitude in isolation is not sufficient to change the attitude as supported by its network. The network structure of attitudes explains why the unchanging minds hypothesis seems to be true, and why it (...) is false: due to the network, the effects of deliberative persuasion are typically latent, indirect, delayed, or disguised. Finally, I connect up the coherence account of attitudes to several topics in recent political and democratic theory. Key Words: deliberation • democracy • persuasion • change in view • coherence.

Newcomb's paradox was first presented by Robert Nozick and has been discussed by a considerable number of writers. You are playing a game with a Being who seems to have extraordinary predictive powers. Before you are two boxes, in one of which you can see $1,000. The other is closed and you cannot see what it contains, but you know that the Being has put a million dollars into it if he has predicted that you will take it only, but (...) nothing if he has predicted that you will take both boxes; you may take either both boxes or the closed one only. The Being has correctly predicted the choices of all who have so far played with him. What should you do?Let us call the Being the seer, and his opponent the player. I should also like to reduce the amount that may, or may not, be in the closed box to $10,000. Nearly everyone could make good use of $1,000 and better use of $10,000 or $11,000, but it is hard to say whether a million dollars would be a blessing or a curse. (shrink)

The paradoxical view of warnock and hodgson that act-Utilitarianism must have disutility is criticised. Simple examples in game theory style show that it does not defeat the possibility of cooperation and that it allows an approximation to truth-Telling. Promising would indeed have only a limited role in an act-Utilitarian society, But that is because its normal function is to aid compromise between divergent purposes. Also, The efforts of a single act-Utilitarian in a non-Act-Utilitarian society need not frustrate themselves, If (...) he is not too candid. (shrink)

Recently, novel lines of research have developed to study the influence of identity processes in sport-related behaviours. Yet, whereas emotions in sport are the result of a complex psychosocial process, little attention has been paid to examining the mechanisms that underlie how group membership influences athletes’ emotional experiences. The present narrative review aims at complementing the comprehensive review produced by Rees et al. (2015) on social identity in sport by reporting specific work on identity-based emotions in sport. To that end, (...) we firstly overview the different terminology currently used in the field of emotions in groups to clarify the distinct nature of emotions that result from an individual’s social identity. Secondly, we discuss key concepts of social identity to better understand the mechanisms underlying identity-based emotions. Thirdly, we address existing knowledge on identity-based emotions in sport. We close the present narrative review by suggesting future research perspectives based on existing meta-theories of social identity. Evidence from the social psychology literature is discussed alongside existing works from the sport literature to propose a crucial theoretical approach to better understand emotions in sport.

It seems plausible to say that what changes an entity can or cannot survive depends on its persistence conditions, and that these depend, in turn, on its sortal kind. It might seem to follow that an entity cannot belong to two sortal kinds with potentially conflicting persistence conditions. Notoriously, though, this conclusion is denied by ‘contingent identity’ theorists, who hold, for example, that a permanently coincident statue and piece of clay are identical, although the persistence conditions associated with the kinds (...) statue and piece of clay are potentially conflicting. A clash with Leibniz’s Law is avoided by treating modal predicates as what Harold Noonan has called ‘Abelardian predicates’, as in the version of ‘inconstant’ counterpart theory developed by David Lewis. In addition to other difficulties, however, there is a question whether this ‘Abelardian’ theory does justice to the intuitions expressed in such statements as that the piece of clay could, while the statue could not, have survived a radical reshaping of its matter. I present an argument, which I call ‘the vacuous satisfaction argument’, for the conclusion that the theory does indeed fail to capture the significance of such de re modal statements. (shrink)

This collection of John Mackie's papers on personal identity and topics in moral and political philosophy, some of which have not previously been published, deal with such issues as: multiple personality; the transcendental "I"; responsibility and language; aesthetic judgements; Sidgwick's pessimism; act-utiliarianism; right-based moral theories; cooperation, competition, and moral philosophy; universalization; rights, utility, and external costs; norms and dilemmas; Parfit's population paradox; and the combination of partially-ordered preferences.

The paper discusses sortal essentialism': the view that some sortal concepts represent essential properties of the things that fall under them. Although sortal essentialism is widely accepted, there is a dearth of theories purporting to explain why some sortals should have this characteristic. The paper examines two theories that do attempt this explanatory task, theories proposed by Baruch Brody and David Wiggins. It is argued that Brody's theory rests on an untenable principle about "de re" modality, while Wiggins' (...) class='Hi'>theory appeals to a thesis about principles of individuation that is either unjustified, or vacuous and incapable of supporting sortal essentialism.
