D.M. Armstrong is an eminent Australian philosopher whose work over many years has dealt with such subjects as: the nature of possibility, concepts of the particular and the general, causes and laws of nature, and the nature of human consciousness. This collection of essays, all specially written for this volume, explore the many facets of Armstrong's work, concentrating on his more recent interests. There are four sections to the book: possibility and identity, universals, laws and causality, philosophy of (...) mind. The contributors comprise an international group of philosophers from the United States, England, and Australia. An interesting feature of the volume is that Armstrong himself has written responses to each of the essays. There is also a complete bibliography of Armstrong's writings. (shrink)

We argue that critiques of political process theory are beginning to coalesce into new approach to social movements--a "multi-institutional politics" approach. While the political process model assumes that domination is organized by and around one source of power, the alternative perspective views domination as organized around multiple sources of power, each of which is simultaneously material and symbolic. We examine the conceptions of social movements, politics, actors, goals, and strategies supported by each model, demonstrating that the view of society and (...) power underlying the political process model is too narrow to encompass the diversity of contemporary change efforts. Through empirical examples, we demonstrate that the alternative approach provides powerful analytical tools for the analysis of a wide variety of contemporary change efforts. (shrink)

This classic work of recent philosophy was first published in 1968, and remains the most compelling and comprehensive statement of the view that the mind is material or physical. In A Materialist Theory of the Mind , D. M. Armstrong provided insight into the debate surrounding the relationship of the mind and body. He put forth a detailed materialist account of all the main mental phenomena, including perception, sensation, belief, the will, introspection, mental images, and consciousness. This causal analysis (...) of mental concepts, along with the similar theory by David Lewis, has come to dominate all subsequent debates in the philosophy of mind. In the preface to this updated edition, Armstrong reflects on the impact of the book, and places it in the context of subsequent developments. A full bibliography of all the key writings that have appeared in the materialist debate is also provided. (shrink)

This is a study of a crucial and controversial topic in metaphysics and the philosophy of science: the status of the laws of nature. D. M. Armstrong works out clearly and in comprehensive detail a largely original view that laws are relations between properties or universals. The theory is continuous with the views on universals and more generally with the scientific realism that Professor Armstrong has advanced in earlier publications. He begins here by mounting an attack on the (...) orthodox and sceptical view deriving from Hume that laws assert no more than a regularity of coincidence between instances of properties. In doing so he presents what may become the definitive statement of the case against this position. Professor Armstrong then goes on to establish his own theory in a systematic manner defending it against the most likely objections, and extending both it and the related theory of universals to cover functional and statistical laws. This treatment of the subject is refreshingly concise and vivid: it will both stimulate vigorous professional debate and make an excellent student text. (shrink)

Truths are determined not by what we believe, but by the way the world is. Or so realists about truth believe. Philosophers call such theories correspondence theories of truth. Truthmaking theory, which now has many adherents among contemporary philosophers, is the most recent development of a realist theory of truth, and in this book D. M. Armstrong offers the first full-length study of this theory. He examines its applications to different sorts of truth, including contingent truths, modal truths, truths (...) about the past and the future, and mathematical truths. In a clear, even-handed and non-technical discussion he makes a compelling case for truthmaking and its importance in philosophy. His book marks a significant contribution to the debate and will be of interest to a wide range of readers working in analytical philosophy. (shrink)

Dispositions are essential to our understanding of the world. IDispositions: A Debate is an extended dialogue between three distinguished philosophers - D.M. Armstrong, C.B. Martin and U.T. Place - on the many problems associated with dispositions, which reveals their own distinctive accounts of the nature of dispositions. These are then linked to other issues such as the nature of mind, matter, universals, existence, laws of nature (...) and causation. (shrink)

The object of this paper is to argue once again for the combinatorial account of possibility defended in earlier work (Armstrong, 1989, 1997). But there I failed fully to realise the dialectical advantages that accrue once one begins by assuming the hypothesis of logical atomism, the hypothesis that postulates simple particulars and simple universals (properties and relations) at the bottom of the world. Logical atomism is, I incline to think, no better than ‘speculative cosmology’ as opposed to ‘analytic ontology’, (...) to use Donald Williams’ terminology (Williams, 1966, p.74). It is, however, not an implausible hypothesis given the current state of quantum physics. More important for our purposes here, the strictly combinatorial theory that flows rather naturally from the atomist metaphysics shows some promise of continuing to hold (perhaps with a little mutatis mutandis) in a world that is not an atomist world.

This major new work by David Armstrong is a contribution to recent philosophical discussions about possible worlds. Taking Wittgenstein's Tractatus as his point of departure, Armstrong argues that non-actual possibilities and possible worlds are recombinations of actually existing elements and as such are useful fictions. Included is an extended criticism of the alternative possible worlds approach championed by the American philosopher David Lewis.

Revenant sur la question des vérifacteurs, D. Armstrong demande ici d'abord comment concilier le maximalisme (toute vérité a un vérifacteur) et la relation de nécessitation (toute vérité contingente peut servir de vérifacteur pour une vérité nécessaire quelconque). L'A. examine quel sens métaphysique donner à la notion d'implication, et s'il y a un sens à admettre une contingence de re. Il traite à ce niveau des possibilités pures, examine le cas des aliens chez <span class='Hi'>David</span> Lewis, puis pose la question (...) de savoir s'il est contingent de dire qu'il y a de l'être plutôt que rien. L'exposé le conduit à traiter du cas des vérifacteurs pour les vérités nécessaires, mais adopte une thèse possibiliste pour les sujets de la science démonstrative. Il se clôt par un examen du genre de nécessité transcatégorielle (et métaphysique) qui est implicite à la généralisation des vérifacteurs. The A. wants to reconcile maximalisme about truthmakers (every truth has a truthmaker) and the relation of necessitation (every contingent truth can be used in a truthmaker for a necessary truth). He investigates the metaphysical sense of the implication and whether one can admit de re contingency. He examines the pure possibilities and the case of alien properties according with <span class='Hi'>David</span> Lewis and studies whether it is contingent that there is something rather than nothing. He analyses the truthmakers of necessary truths and adopts a possibilist thesis for matters of demonstrative science. He concludes with the transcategorial (and metaphysical) necessity which is implicit in the generalization of truthmakers. (shrink)

'With this scheme, John Anderson joins a very distinguished line of philosophers who have presented us with a set of categories. We have first Plato (the doctrine of Highest Kinds in his dialogue The Sophist), then Aristotle, Kant, Hegel, and Samuel Alexander.' - D. M. Armstrong, from the introduction. Space, Time and the Categories presents a unique record of personal influence and inspiration over three generations of philosophers in Australia, England and Scotland. This work is a vitally important text (...) in the history of the development of realist philosophy in Australian universities. With an introduction by Emeritus Professor D M Armstrong whose own student notes are the basis for the text used, this book brings together three of the major figures in the history of Australian philosophy.

Over 700,000 copies of the original hardcover and paperback editions of this stunningly popular book have been sold. Karen Armstrong's superbly readable exploration of how the three dominant monotheistic religions of the world—Judaism, Christianity, and Islam—have shaped and altered the conception of God is a tour de force. One of Britain's foremost commentators on religious affairs, Armstrong traces the history of how men and women have perceived and experienced God, from the time of Abraham to the present. From (...) classical philosophy and medieval mysticism to the Reformation, the Enlightenment, and the modern age of skepticism, Armstrong performs the near miracle of distilling the intellectual history of monotheism into one compelling volume.

In this short text, a distinguished philosopher turns his attention to one of the oldest and most fundamental philosophical problems of all: How it is that we are able to sort and classify different things as being of the same natural class? Professor Armstrong carefully sets out six major theories—ancient, modern, and contemporary—and assesses the strengths and weaknesses of each. Recognizing that there are no final victories or defeats in metaphysics, Armstrong nonetheless defends a traditional account of universals (...) as the most satisfactory theory we have.This study is written for advanced students, but as Armstrong goes considerably beyond his earlier work on this topic, it will interest professional scholars as well. Carefully plotted and clearly written, Universals is both a paradigm of exposition and a case study on the value of careful analysis of fundamental issues in philosophy. (shrink)

The Animal Ethics Reader is the first comprehensive, state-of-the-art anthology of readings on this substantial area of study and interest. A subject that regularly captures the headlines, the book is designed to appeal to anyone interested in tracing the history of the subject, as well as providing a powerful insight into the debate as it has developed. The recent wealth of material published in this area has not, until now, been collected in one volume. Readings are arranged thematically, carefully presenting (...) a balanced representation of the subject as it stands. It will be essential reading for students taking a course in the subject as well as being of considerable interest to the general reader. Articles are arranged under the following headings: Theories of Animal Ethics; Animal Capacities; Animals for Food; Animal Experimentation; Genetic Engineering of Animals; Ethics and Wildlife; Zoos, Aquaria, and Animals in Entertainment; Companion Animals; Legal Rights for Animals. Readings from leading experts in the field including Peter Singer, Mary Midgley and Bernard Rollin are featured as well as selections from Donald Griffin, Mark Bekoff, Jane Goodall, Raymond Frey, Barbara Orlans, Tom Regan, and Baird Callicott. There is an emphasis on balancing classic and contemporary readings with a view to presenting debates as they stand at this point in time. Each chapter is introduced by the editors and study questions feature at the end. The foreword has been written by Bernard Rollin. (shrink)

In the ninth century BCE, the peoples of four distinct regions of the civilized world created the religious and philosophical traditions that have continued to nourish humanity to the present day: Confucianism and Daoism in China, Hinduism and Buddhism in India, monotheism in Israel, and philosophical rationalism in Greece. Later generations further developed these initial insights, but we have never grown beyond them. Rabbinic Judaism, Christianity, and Islam, for example, were all secondary flowerings of the original Israelite vision. Now, in (...) The Great Transformation , Karen Armstrong reveals how the sages of this pivotal “Axial Age” can speak clearly and helpfully to the violence and desperation that we experience in our own times. Armstrong traces the development of the Axial Age chronologically, examining the contributions of such figures as the Buddha, Socrates, Confucius, Jeremiah, Ezekiel, the mystics of the Upanishads, Mencius, and Euripides. All of the Axial Age faiths began in principled and visceral recoil from the unprecedented violence of their time. Despite some differences of emphasis, there was a remarkable consensus in their call for an abandonment of selfishness and a spirituality of compassion. With regard to dealing with fear, despair, hatred, rage, and violence, the Axial sages gave their people and give us, Armstrong says, two important pieces of advice: first there must be personal responsibility and self-criticism, and it must be followed by practical, effective action. In her introduction and concluding chapter, Armstrong urges us to consider how these spiritualities challenge the way we are religious today. In our various institutions, we sometimes seem to be attempting to create exactly the kind of religion that Axial sages and prophets had hoped to eliminate. We often equate faith with doctrinal conformity, but the traditions of the Axial Age were not about dogma. All insisted on the primacy of compassion even in the midst of suffering. In each Axial Age case, a disciplined revulsion from violence and hatred proved to be the major catalyst of spiritual change. (shrink)

A graceful and lucid study of the power of beauty and the deep significance it has in our lives In defining beauty and our response to it, we are often caught between the concrete and the sublime. We wish to categorize beauty, to clearly label its parts, and yet we wish also to celebrate its mysterious-and at times mythical-power. Armstrong's response is a discursive and graceful journey through various and complementary interpretations, leading us from Hogarth's belief that the essence (...) of beauty lies in shapely curves, to Kant's discourses on the meaning of pleasure.

In response to Mader's and Deutscher's questions, the author defends her approach to reading Irigaray and Butler, which entails extending the ideas of these thinkers into areas of thought with which they do not engage directly themselves. This involves relating Irigaray's ideas to the tradition of the philosophy of nature and interpreting Butler as offering, in spite of her focus on the genealogy of claims about sex, also a theory of sex itself, a theory of sex as an effect entirely (...) of gender. This approach to reading differs from Irigaray's own reading method of expanding and transforming philosophies in light of their constitutive exclusions. An example of this, explored here, is Irigaray's expansion and transformation of Merleau-Ponty's late ontology of flesh in light of its constitutive exclusion, the "maternal sojourn." This article also asks whether rhythmic sexual difference, which the author has attempted to differentiate from biological sex difference, ultimately remains tied to biological sex difference. This commentary suggests that it does but that reference to biological sex difference need not be politically problematic. Finally, the author asks whether the metaphysics of potentials and tendencies that she attributes to Irigaray impedes social change by inevitably reinstalling the actual as the horizon of possibility. Irigaray's strategy of reading texts and cultures for their constitutive exclusions offers a solution to this problem. (shrink)

I show that Armstrong’s view of laws as second-order contingent relations of ‘necessitation’ among categorical properties faces a dilemma. The necessitation relation confers a relation of extensional inclusion (‘constant conjunction’) on its relata. It does so either necessarily or contingently. If necessarily, it is not a categorical relation (in the relevant sense). If contingently, then an explanation is required of how it confers extensional inclusion. That explanation will need to appeal to a third-order relation between necessitation and extensional inclusion. (...) The same dilemma reappears at this level. Either Armstrong must concede that some properties are not categorical but have essential powers – or he is faced with a regress. (shrink)

: If liberal theory is to move forward, it must take the political nature of family relations seriously. The beginnings of such a liberalism appear in Mary Wollstonecraft's work. Wollstonecraft's depiction of the family as a fundamentally political institution extends liberal values into the private sphere by promoting the ideal of marriage as friendship. However, while her model of marriage diminishes arbitrary power in family relations, she seems unable to incorporate enduring sexual relations between married partners.

This article argues that there is a great divide between semantics and metaphysics. Much of what is called metaphysics today is still stuck in the linguistic turn. This is illustrated by showing how Fraser MacBride misunderstands David Armstrong's theory of modality.

Walter Sinnott-Armstrong's recent defense of moral skepticism raises the debate to a new level, but I argue that it is unsatisfactory because of problems with its assumption of global skepticism, with its use of the Skeptical Hypothesis Argument, and with its use of the idea of contrast classes and the correlative distinction between "everyday" justification and "philosophical" justification. I draw on Chisholm's treatment of the Problem of the Criterion to show that my claim that I know that, e.g., baby-torture (...) is wrong, is no more question-begging than Sinnott-Armstrong's denial that I know this.

Mary is confined to a black-and-white room, is educated through black-and-white books and through lectures relayed on black-and white television. In this way she learns everything there is to know about the physical nature of the world. She knows all the physical facts about us and our environment, in a wide sense of 'physical' which includes everything in completed physics, chemistry, and neurophysiology, and all there is to know about the causal and relational facts consequent upon all this, including (...) of course functional roles. If physicalism is true, she knows all there is to know. For to suppose otherwise is to suppose that there is more to know than every physical fact, and that is just what physicalis.. (shrink)

In this article, I will focus on the notion of supervenience introduced and deployed by Armstrong. The aim is to settle the issue of whether it has any fruitful applications. My conclusions are negative. Armstrong gives to his notion of supervenience a major explanatory role of telling why one need not consider certain beings as a genuine ontic expansion, if one already assumes a certain meagre set of more basic entities. On closer inspection, however, Armstrong’s notion does (...) not clarify such intuitions any further. The legitimate uses of the notion for the above purpose turn out to be redundant: the concepts of identity and partial identity can be employed instead. (shrink)

Feared and admired in equal measure, Mary Midgely has carefully, yet profoundly challenged many of the scientific and moral orthodoxies of the twentieth century. The Essential Mary Midgley collects for the first time the very best of this famous philosopher's work, described by the Financial Times as "commonsense philosophy of the highest order." This anthology includes carefully chosen selections from her best-selling books, including Wickedness, Beast and Man, Science and Poetry and The Myths We Live By . It (...) provides a superb and eminently accessible insight into questions she has returned to again and again in her renowned sharp prose, from the roots of human nature, reason and imagination to the myths of science and the importance of holism in thinking about science and the environment. It offers an unrivalled introduction to a great philosopher and a brilliant writer, and also includes a specially written foreword by James Lovelock. (shrink)

The paper treats several ontological questions about certain nineteenth-century and contemporary medical and scientific conceptualizations of hereditary relation. In particular, it considers the account of mid-nineteenth century psychiatric thought given by Foucault in Psychiatric Power: Lectures at the Collège de France, 1973–1974 and Abnormal: Lectures at the Collège de France, 1974–1975 . There, Foucault argues that a fantastical conceptual prop, the ‘metabody,’ as he terms it, was implicitly supposed by that period’s psychiatric medicine as a putative ground for psychiatric pathology. (...) After presenting the heart of Foucault’s thought on the ‘metabody,’ the paper investigates the possibility that a contemporary version of a ‘metabody’ may operate today as a conceptual analog of the nineteenth-century psychiatric theory and practice that Foucault began to expose in the texts examined here. It speculates that we might identify a contemporary genetic version of a ‘metabody’ in a particular current conception of the gene as replicator, an item marked by an ambiguous temporal ontology.

In recent works, Luce Irigaray offers arguments for the establishment of sexed rights that rely upon certain presuppositional accounts of the development of relational sexuate identity and difference. The paper advances a series of objections to these accounts, in addition to examining some of Irigaray's proposals concerning women's indefinition, the category of the neuter, and female genealogy. Supplementing Luce Irigaray's argument that mother-daughter genealogy is under-symbolized in present Occidental cultures, it suggests, for reasons consonant with Irigaray's general project, additional corrective (...) representation of paternal genealogy in terms of father-daughter relations.

This analysis explores the phenomenology of suffering and temporal, genetic and social developmental aspects of suffering for seriously ill older adults. A phenomenological account of suffering is advanced using oral history data from in-depth interviews with a seriously ill, frail elderly woman. The analysis evaluates how a phenomenological account of suffering may inform ethics in end-of-life decision making, and may provide a further basis for an integrated ethical and gerontological response to suffering in palliative social work practice with seriously ill (...) older adults at the end of life. Levinas’s ethical philosophy and conceptualizations of the non-totalizing relation of self to other, disinterest, and radical passivity are employed to help reframe an approach to the ethical relation and the nature of obligation in end-of-life care, expanding consciousness of suffering and its meanings in an intersubjectively experienced world. Differences in Husserl’s account of the other and the concept of alterity in Levinas’s ethics are explored in the context of phenomenology as a descriptive science that respond directly to the pragmatic concerns of the analysis.

Frank Jackson’s knowledge argument (KA) aims to prove, by means of a thought experiment concerning the hypothetical scientist Mary, that conscious experiences have non-physical properties, called qualia. Mary has complete scientific knowledge of colours and colour vision without having had any colour experience. The central intuition in the KA is that, by seeing colours, Mary will learn what it is like to have colour experiences. Therefore, her scientific knowledge is incomplete, and conscious experiences have qualia. In this (...) paper I consider an objection to the KA raised by Daniel Dennett. He maintains that the KA is vitiated by Jackson’s account of Mary’s scientific knowledge. While endorsing this criticism, I will defend the plausibility and relevance of the type of strategy involved in the KA by offering an account of Mary’s scientific knowledge. This account involves formulating a reasonable and not immediately false version of the physicalist thesis with regard to colour experiences. Whether this version of the KA is successful against this type of physicalism is not investigated here. (shrink)

Walter Sinnott-Armstrong has argued against moral intuitionism, according to which some of our moral beliefs are justified without needing to be inferred from any other beliefs. He claims that any prima facie justification some non-inferred moral beliefs might have enjoyed is removed because many of our moral beliefs are formed in circumstances where either (1) we are partial, (2) others disagree with us and there is no reason to prefer our moral judgement to theirs, (3) we are emotional in (...) a way that clouds our judgement, (4) the circumstances are conducive to illusion, or (5) the source of our moral beliefs is unreliable or disreputable. I take issue with the elements of Sinnott-Armstrong’s argument that centre on (1) to (3) and (5), concluding that his case against moral intuitionism is unpersuasive. (shrink)

Jackson's black-and-white Mary teaches us that the propositional content of perception cannot be fully expressed in language.

In a series of recent papers, Walter Sinnott-Armstrong has used findings in social psychology to put pressure on the claim that our moral beliefs can be non-inferentially justified. More specifically, he has suggested that insofar as our moral intuitions are subject to what psychologists call framing effects, this poses a real problem for moral intuitionism. In this paper, we are going to try to add more fuel to the empirical fire that Sinnott-Armstrong has placed under the feet of (...) the intuitionist. Along the way, we first provide an overview of what Sinnott-Armstrong calls the Master Argument against intuitionism. Then we examine some of the literature on framing effects—especially as it pertains to moral philosophy. Finally, we present the results of a new study which create yet another hurdle intuitionists must clear if they want to motivate their view. It appears that in addition to being influenced by framing effects, our moral intuitions are also influenced by an actor–observer bias as well—a bias whereby we hold other people to different moral standards than we would hold ourselves even if we were in the same situation. If we’re right, the burden is on the moral intuitionist to explain why we should have faith in our moral intuitions despite the gathering evidence concerning their seeming unreliability. And by our lights, this is something that simply cannot be done from the armchair. (shrink)

Mary knows all there is to know about physics, chemistry and neurophysiology, yet has never experienced colour. Most philosophers think that if Mary learns something genuinely new upon seeing colour for the first time, then physicalism is false. I argue, however, that physicalism is consistent with Mary's acquisition of new information. Indeed, even if she has perfect powers of deduction, and higher-level physical facts are a priori deducible from lower-level ones, Mary may still lack concepts which (...) are required in order to deduce from the lower-level physical facts what it is like to see red.

Resemblances obtain not only between objects but between properties. Resemblances of the latter sort - in particular resemblances between quantitative properties - prove to be the downfall of a well-known theory of universals, namely the one presented by David Armstrong. This paper examines Armstrong's efforts to account for such resemblances within the framework of his theory and also explores several extensions of that theory. All of them fail.

This collection of previously unpublished essays addresses a number of issues arising out of philosophical controversies over the possibility of genuine moral dilemmas. Issues addressed include the form of a moral dilemma; the paradoxes a moral dilemma is said to entail; the question of whether a moral dilemma must exhibit inconsistency; the role of intractable circumstances in occasioning moral dilemmas; and the plausibility of supposing that there might be rational ways of addressing moral dilemmas in practice. The contributors, writing from (...) a number of widely differing points of view, include Simon Blackburn, Ruth Barcan Marcus, Alan Donagan, Terrance McConnell, Walter Sinnott-Armstrong, Mary Mothersill, Norman Dahl, David Brink, Peter Railton, Thomas E. Hill, Jr., Christopher Gowans, and H.E. Mason. (shrink)

In 1997, David Armstrong argued that the world is a world of states of affairs. In his latest book, Truth and Truthmakers, he remains strongly committed to the existence of states of affairs, despite now advocating an ontology in which they are not needed, 'as an ontological extra'. States of affairs remain needed, Armstrong says, 'to act as truthmakers for predicative truths'. In this paper, I attempt to shed light on what Armstrong might mean by this claim. (...) While there is a straightforward sense in which states of affairs are not needed in Armstrong's amended ontology, I suggest that Armstrong might be charitably interpreted in a manner that justifies his claim. However, in clarifying the manner in which states of affairs remain needed in Armstrong's ontology, it becomes unclear whether they are needed in any 'deep' sense, or rather are merely parochial to his ontology. I examine Armstrong's rejection of Resemblance Nominalism on the grounds that it does not provide adequate 'minimal' truthmakers. I then argue that he has significant additional work to do in explaining this concept before his rejection of Resemblance Nominalism can be justified, and thus before the need for states of affairs can be asserted generally, rather than just within particular ontologies, such as Armstrong's amended one.

Armstrong's combinatorialism, in his own words, is the following project: "My central metaphysical hypothesis is that all there is is the world of space and time. It is this world which is to supply the actual elements for the totality of combinations. So what is proposed is a Naturalistic form of a combinatorial theory."2 Armstrong calls his central hypothesis "Naturalism." He intends his well−known theory of universals to satisfy this thesis. He now attempts to give a naturalistic theory (...) of modality. (shrink)

I argue for the superiority of non-gappy physicalism over gappy physicalism. While physicalists are united in denying an ontological gap between the phenomenal and the physical, the gappy affirm and the non-gappy deny a relevant epistemological gap. Central to my arguments will be contemplation of Swamp Mary, a being physically intrinsically similar to post-release Mary (a physically omniscient being who has experienced red) but has not herself (the Swamp being) experienced red. Swamp Mary has phenomenal knowledge of (...) a phenomenal character not instantiated by any of her past or current mental states. I issue a challenge to gappy physicalists to account for how it is that Swamp Mary can satisfy the psychosemantic requirements on phenomenal knowledge while non-Swamp pre-release Mary cannot. I argue that gappy physicalists cannot meet this psychosemantic challenge. (shrink)

In 1999, Jeffrey Ketland published a paper which posed a series of technical problems for deflationary theories of truth. Ketland argued that deflationism is incompatible with standard mathematical formalizations of truth, and he claimed that alternate deflationary formalizations are unable to explain some central uses of the truth predicate in mathematics. He also used Beth’s definability theorem to argue that, contrary to deflationists’ claims, the T-schema cannot provide an ‘implicit definition’ of truth. In this article, I want to challenge (...) this final argument. Whatever other faults deflationism may have, the T-schema does provide an implicit definition of the truth predicate. Or so, at any rate, I shall argue. (shrink)
