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)

I argue against a view of the individuation of actions endorsed most notably by Hornsby and Davidson. This is the view that in, for example, Anscombe’s case of the pumping man, we have a single action which can be described, variously, as a pumping, a poisoning and so on. I argue that, even in the area of the standard arguments against this view, such as that based on the logic of ‘by’ and the argument from temporal dimensions, the case against (...) the Davidson‐Hornsby view has not been made as strong as it ought to have been. I show how those standard arguments can be strengthened; and I argue that the principal considerations adduced in support of the view do not in fact lend it the support that they have been widely thought to lend it. I conclude that the view should be rejected. (shrink)

The view that people go where their brains go remains popular in discussions of personal identity. But since the brain is only a small part of the body, defenders of that view need to provide an account of what it is that makes the brain specially relevant to personal identity. The standard answer is that the brain is special because it is the carrier of psychological continuity. But Peter van Inwagen has recently offered (in Material Beings) an alternative account of (...) the brain' special relevance. Those who reject the view that we go with our brains obviously need to respond to this new account. According to van Inwagen, there is an important difference between the life-support requirements of a severed head and those of a headless body: whereas a severed head would need only a pump to survive, a headless body would need the functional equivalent of a computer in its life-support system. It follows, according to van Inwagen, that we go with our brains. In this paper I argue that van Inwagen's argument is doubly defective: the inference from his premisses to his conclusion is dubious; and in any case his premisses misrepresent the relevant physiological facts. (shrink)

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)

I argue that David Lewis’s attempt, in his ‘Counterfactual Dependence and Time’s Arrow’, to explain the fixity of the past in terms of counterfactual independence is unsuccessful. I point out that there is an ambiguity in the claim that the past is counterfactually independent of the present (or, more generally, that the earlier is counterfactually independent of the later), corresponding to two distinct theses about the relation between time and counterfactuals, both officially endorsed by Lewis. I argue that Lewis’s (...) attempt is flawed for a variety of reasons, including the fact that his own theory about the evaluation of counterfactuals requires too many exceptions to the general rule that the past is counterfactually independent of the present. At the end of the paper, I consider a variant of Lewis’s strategy that attempts to explain the fixity of the past in terms of causal, rather than counterfactual, independence. I conclude that, although this variant avoids some of the objections that afflict Lewis’s account, it nevertheless seems to be incapable of giving a satisfactory explanation of the notion of the fixity of the past.

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' theory (...) appeals to a thesis about principles of individuation that is either unjustified, or vacuous and incapable of supporting sortal essentialism.

Available from UMI in association with The British Library. Requires signed TDF. ;The main part of the thesis concerns how things, in the sense of individuals, might have been. The topic is what limits there are on the counterfactual possibilities for individuals: in other words, what essential properties, if any, they have. ;In Chapters 3-6 three answers to this question that have been given in recent philosophical literature are examined. They are: that each thing has a unique individual essence ; (...) that there are features of the origin of an individual without which it could not possibly have existed ; and, finally, that there are sortal concepts that represent essential properties of the things that fall under them . ;All of these answers, and many of the arguments that have been given for them, are criticised. Sometimes the criticism takes the form of pointing to unpalatable consequences that result from the acceptance of the doctrine in question. Sometimes the criticism consists in pointing to difficulties or inadequacies in the arguments that have been presented in its favour. ;A preliminary chapter prepares the ground by setting out the conceptual framework, and the chief formal characteristics, of the essentialism discussed in the later chapters. Chapter 2 discusses the nature of necessary a posteriori truth, touching on questions in the philosophy of language and mind concerning the notion of de re thought. ;It is argued that essentialism about natural kinds raises problems of its own: some of these are discussed in Chapters 7 and 8. Here the main topic is the connection between semantic theory and natural kind essentialism. Concluding that the essentialism should be regarded as in an important sense independent of semantic theory, the chapters add to, and also criticise, the work of other writers who have reached the same verdict. Scepticism is also expressed about the independent plausibility of natural kind essentialism. ;Recent interest in essentialism owes its genesis chiefly to the work of Saul Kripke and Hilary Putnam: these figures stand in the background throughout the discussion. Among the other writers whose work is discussed are Baruch Brody, Gareth Evans, Graeme Forbes, Colin McGinn, J. L. Mackie, D. H. Mellor, Nathan Salmon, and David Wiggins. (shrink)

I argue that Mackie's approach to practical reasons is attractive and unjustly neglected. In particular I argue that it is much more plausible than the kind of instrumentalist approach famously articulated by Bernard Williams. This matters for Mackie's arguments for moral skepticism. Contra Richard Joyce, I argue that it is a serious mistake to invoke instrumentalism in arguing for moral skepticism.

I criticize and emend J L Mackie's account of causal priority by replacing ‘fixity’ in its central clause by 'x is a causal condition of y, but y is not a causal condition of x'. This replacement works only if 'is a causal condition of' is not a symmetric relation. Even apart from our desire to account for causal priority, it is desirable to have an account of nonsymmetric conditionship. Truth, for example, is a condition of knowledge, but knowledge (...) is not a condition of truth. My definitions of 'sufficient condition for' and 'necessary condition for' do not imply that p is a sufficient condition of q if and only if q is a necessary condition of p. (shrink)

[Open access] In this book symposium the author takes up questions from phenomenology, hermeneutics, ethical theory, and intellectual history raised by a group of scholarly interlocutors from a range of backgrounds. In the course of engaging with these issues, he discusses, inter alia, McDowell’s realism, Jonathon Lear’s work on the end of a world, Michael Oakeshott’s view of selfhood, Heidegger’s conception of Jemeinigkeit, Uexküll’s notion of Umwelt, and Gadamer’s hermeneutic conception of truth.

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.

In “The possibility of morality,” Phil Brown considers whether moral error theory is best understood as a necessary or contingent thesis. Among other things, Brown contends that the argument from relativity, offered by John Mackie—error theory’s progenitor—supports a stronger modal reading of error theory. His argument is as follows: Mackie’s is an abductive argument that error theory is the best explanation for divergence in moral practices. Since error theory will likewise be the best explanation for similar divergences in (...) possible worlds similar to our own, we may conclude that error theory is true at all such worlds, just as it is in the actual world. I contend that Brown’s argument must fail, as abductive arguments cannot support the modal conclusions he suggests. I then consider why this is the case, concluding that Brown has stumbled upon new and interesting evidence that agglomerating one’s beliefs can be epistemically problematic—an issue associated most famously with Henry Kyburg’s lottery paradox.

David Johnson seeks to overthrow one of the widely accepted tenets of Anglo-American philosophy—that of the success of the Humean case against the rational credibility of reports of miracles. In a manner unattempted in any other single work, he meticulously examines all the main variants of Humean reasoning on the topic of miracles: Hume's own argument and its reconstructions by John Stuart Mill, J. L. Mackie, Antony Flew, Jordan Howard Sobel, and others. Hume's view, set forth in his (...) essay "Of Miracles," has been widely thought to be correct. Johnson reviews Hume's thesis with clarity and elegance and considers the arguments of some of the most prominent defenders of Hume's case against miracles. According to Johnson, the Humean argument on this topic is entirely without merit, its purported cogency being simply a philosophical myth. (shrink)

The paper, based on the H.L.A. Hart Memorial Lecture in Jurisprudence and Moral Philosophy, delivered in Oxford on 11th May 2004, sets out to answer two difficulties which the late J. L. Mackie proposed (in his book Ethics: Inventing Right & Wrong) against the idea of objectivity in ethics. These were (1) the metaphysical peculiarity (‘queerness’) of values and obligations and (2) the ‘well known variation in moral codes from one society to another’ (‘relativity’). It is argued that the (...) true import of Mackie's two difficulties is that they are a challenge to us to study with closer attention the dialectical and conceptual resources of ethical thinking. In the answer to the second difficulty, the ethic of globalism is revealed as a gross misunderstanding of true internationalism.1. (shrink)

I revise J L Mackie's first account of casual direction by replacing his notion of "fixity" by a newly defined notion of "sufficing" that is designed to accommodate indeterminism. Keeping Mackie's distinction between casual order and casual direction, I then consider another revision that replaces "fixity" with "one-way conditionship". In response to the charge that all such accounts of casual priority beg the question by making an unjustified appeal to temporal priority, i maintain that one-way conditionship explains rather (...) that assumes objective temporal dependence as well as objective casual dependence.

In 1974, George Grant delivered the Josiah Wood lectures at Mount Allison University on the theme English-Speaking Justice. The lectures, first published in 1978, have been republished, and a volume of later essays on somewhat related themes has recently appeared. Grant's work offers an impressionistic but deep challenge to the conception of justice in modern moral thought and practice, a challenge paralleled, in interesting and important ways, by concerns about morality raised in the writings of such persons as Alasdair MacIntyre, (...) Bernard Williams, and, perhaps more surprisingly, J. L. Mackie. In this review, I want briefly to expound Grant's treatment of justice, to exhibit its relationships to other disquieting accounts, and to suggest some of the resources available to contractarian moral theory for lightening what for Grant is a terrifying darkness.

David Hume's greatness depends in large part on how his writings hint at beautiful and coherent theories which are recognizably Humean despite their divergences from the untidy originals. Now, perhaps the clearest vision of a contradiction–free Platonic Form of Hume was had by J. L. Mackie; he described it in such masterpieces as The Cement of the Universe, Ethics: Inventing Right and Wrong, and The Miracle of Theism. How successful is this last in its attack on theism? I (...) shall discuss Mackie's case against theism of a Platonic or Neoplatonic type which replaces ‘God as a person or mind or spirit’ by a more abstract Creative Force or Principle. Mackie sees in it a ‘a formidable rival’ to any theism treating of a divine being; ‘if you demand an ultimate explanation, then this may well be a better one’ . But, his chapter thirteen contends, it fares badly in competition with an atheistic, naturalistic approach. (shrink)

The late J. L. Mackie and his work were a focus for much of the best philosophical thinking in the Oxford tradition.

Five of the essays give a new understanding of the objectivity of moral judgements. These are by Simon Blackburn, R.M. Hare, John McDowell, Susan Hurley and Bernard Williams. The remaining contributors – Philippa Foot, Steven Lukes, Amartya Sen, David Wiggins – give their attention to problems which are equally compelling, such as the defence of a moral outlook based on a conception of a need and of what follows from it. The volume also includes the addresses given by Simon Blackburn and George Cawkwell at the memorial service for John Mackie, and a list of his publications, compiled by Joan Mackie. (shrink)

I respond to criticisms by David Mackie of my previous paper on animalism and Lockeanism. I argue that the ‘transplant intuition’, that a person goes where his brain (or cerebrum) goes, is compatible both with animalism and Lockeanism. I give three arguments for this conclusion, two of them developing lines of thought in Parfit's work. However, I accept that animalism and Lockeanism are incompatible, and I go on to consider the difficulties for Lockeanism that this raises. The principal (...) difficulty, concerning the reference of ‘I’, can be met by distinguishing the thinker of an ‘I’‐thought from the reference of an ‘I’‐thought. The reference is always the person thinking the thought, but when the thought is simultaneously that of an animal coincident but non‐identical with that person, there is not a unique thinker. Mackie's criticisms of this view are ineffective. (shrink)

In this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a (...) form of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

David Hume's claim that necessary connection is essential to causality was at the expense of a useful causal distinction we sometimes note with the words ‘necessity’ and ‘contingency’. And since, as J. L. Mackie has stated, Hume made ‘the most significant and influential single contribution to the theory of causation’, subsequent writers on causality, regardless of their support for, or opposition to, Hume, have joined him in trampling this distinction. The object of this paper is not so much (...) to undermine one of Hume's conclusions as it is to describe a use of ‘necessary’ that, while surviving in popular usage, is ignored or obfuscated in the literature on causality.

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

A collection of 14 essays honoring the life and work of Oxford philosopher Wiggins touching on topics from ancient philosophy to ethics, metaphysics and the theory of meaning. The contributing scholars debate many of the seminal issues of Wiggins' work, including the determinancy of distinctness, relative identity, naturalism in ethics, logic and truth in moral judgments, and the practical wisdom of Aristotle. The collection uniquely features replies by Wiggins to each of the papers. Annotation copyright by Book News, Inc., Portland, (...) OR. (shrink)

The volume delves into the latest theoretical controversies as well as burning questions of contemporary social importance. The issues considered include the nature of evolutionary theory, biology and ethics, the challenge from religion, and the social implications of biology today (in particular the Human Genome Project).

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.

According to dispositionalism about modality, a proposition <p> is possible just in case something has, or some things have, a power or disposition for its truth; and <p> is necessary just in case nothing has a power for its falsity. But are there enough powers to go around? In Yates (2015) I argued that in the case of mathematical truths such as <2+2=4>, nothing has the power to bring about their falsity or their truth, which means they come out both (...) necessary and not possible. Combining this with axiom (T), it is easy to derive a contradiction. I suggested that dispositionalists ought to retreat a little and say that <p> is possible just in case either p, or there is a power to bring it about that p, grounding the possibility of mathematical propositions in their truth rather than in powers. Vetter’s (2015) has the resources to provide a response to my argument, and in her (2018) she explicitly addresses it by arguing for a plenitude of powers, based on the idea that dispositions come in degrees, with necessary properties a limiting case of dispositionality. On this view there is a power for <2+2=4>, without there being a power to bring about its truth. In this paper I argue that Vetter’s case for plenitude does not work. However, I suggest, if we are prepared to accept metaphysical causation, a case can be made that there is indeed a power for <2+2=4>. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

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.
