This article considers an interpretative model for the study of Heraclitus, which was first put forward by Alexander Mourelatos in 1973, and draws upon a related model put forward by Julius Moravcsik beginning in 1983. I further develop this combined model and provide a motivation for an interpretation of Heraclitus. This is also of interest for modern metaphysics due to the recurrence of structurally similar problems, including the ‘colour exclusion’ problem that was faced by Wittgenstein. Further, I employ the model (...) to shed new light on Heraclitus’ image of the river, while relating potential readings to various contemporary metaphysical views. (shrink)

Jerrold J. Katz often explained his semantic theory by way of an analogy with physical atomism and an attendant analogy with chemistry. In this chapter, I track the origin and uses of these analogies by Katz, both in explaining and defending his decompositional semantic theory, through the various phases of his work throughout his career.

I offer an examination of a core element in the reflectiveness of Heraclitus’ thought, namely, his rebuke of polymathy . In doing so, I provide a response to a recent claim that Heraclitus should not be considered to be a philosopher, by attending to his paradigmatically philosophical traits. Regarding Heraclitus’ attitude to that naïve form of ‘wisdom’, i.e., polymathy, I argue that he does not advise avoiding experience of many things, rather, he advises rejecting experience of things as merely many (...) independent things in their manifoldness , and, instead, to understand their unity and thereby to unify our knowledge of them.

The three main kinds of theory in normative ethics, namely, consequentialism, deontology, and virtue ethics, are often presented as the ‘palette’ from which we may choose, or use as a starting point for an investigation. However, this way of doing ethics and philosophy, by the palette, may be leading some of us astray. It has led some to believe that all that there is to ethics, and to ethics of AI, is given in terms of these already devised petrified categories (...) of theory. It has also led others to abandon normative ethics and philosophy altogether and to resort to descriptive methods that are then used to justify action. I wish to argue that (1) we should not abandon traditional philosophical approaches, but (2a) this does not entail that the petrified palette should constitute the beginning of our philosophical investigations. Further, (2b) I recommend a non-methodological approach in which it is instead radical questions that spur these investigations, which arise through consideration of the practical actions (potential or otherwise) of machines and their programmers.

This chapter discusses the nature of software maintenance in light of software’s ontological status. A realist view of software need not commit us to the otiose position that software maintenance is impossible. Many philosophers and computer scientists have been concerned with drawing attention to software’s dual nature, its being both symbolic and physical, abstract and concrete. There are strong connections to be found between this topic and recent investigations in the philosophy of linguistics, particularly the metaphysics of words. It is (...) shown, contra Irmak, that software can be best understood through a realist type-token distinction employing an ontology of composite objects that was put forward by Katz. This approach employs both non-spatiotemporal abstract types and tokens of those types. Further developing Katz’s realist approach can help to make better sense of the dual nature of computational artefacts and their maintenance than the alternatives outlined. Young claims that a prevalent imbalanced view of maintenance as solely conservative is due to a misunderstanding of the nature of artefacts as being realisations of their producers’ intentions. This is a problem for theories of artefacts that employ intentions, such as the one involved with the realist view of software and software maintenance. Software maintenance on this view is not solely conservative but also adaptive and enhancive, constituting a source of counterexamples to Young’s claim. An alternative explanation of the imbalanced view is provided, based on observations by software engineers, especially Sommerville. (shrink)

In the recent literature on the ontology and metaphysics of words, Jerrold J. Katz’ type-realist or ‘Platonist’ view is often mentioned but never spelt out in detail. This is perhaps understandable in light of the fact that his most developed statements on this matter are effectively offshoots of his main discourse in Realistic Rationalism (Katz, 1998a). His direct statements about the metaphysics of words are few and far between and are scattered across the text. This situation has often led to (...) misunderstandings or misconstruals about the exact nature of his view, some of which is buried in footnotes, and some of which must be reconstructed. Hence, criticisms of Katz’ approach have been wide of the mark or otherwise unproductive. In this article, I provide a remedy for this situation by drawing together and abstracting the relevant material regarding the metaphysics of words from its context and reconstructing the theory. I also develop the view further through resolving some potential problems and omissions, and by responding to recent criticism that the approach has received in the burgeoning literature on the philosophy of words. I hope that this will help to clarify the theory and lead to further debate and development on all sides of the discussion. (shrink)

"It’s a beautiful thing, the destruction of words. Of course the great wastage is in the verbs and adjectives, but there are hundreds of nouns that can be got rid of as well. It isn’t only the synonyms; there are also the antonyms. After all, what justification is there for a word which is simply the opposite of some other word? A word contains its opposite in itself. Take “good”, for instance. If you have a word like “good”, what need (...) is there for a word like “bad”? “Ungood” will do just as well — better, because it’s an exact opposite, which the other is not." (Syme, in George Orwell's Nineteen Eighty-Four) This chapter is about opposites and Newspeak in Orwell's Nineteen Eighty-Four. (shrink)

Shared decision-making involves health professionals and patients/clients working together to achieve true person-centred health care. However, this goal is infrequently realized, and most barriers are unknown. Discussion between philosophers, clinicians, and researchers can assist in confronting the epistemic and moral basis of health care, with benefits to all. The aim of this paper is to describe what shared decision-making is, discuss its necessary conditions, and develop a definition that can be used in practice to support excellence in maternity care. Discussion (...) between the authors, with backgrounds in philosophy, clinical maternity care, health care management, and maternity care research, assisted the team to confront established norms in maternity care and challenge the epistemic and moral basis of decision-making for caesarean section. The team concluded that shared decision-making must start in pregnancy and continue throughout labour and birth, with equality in discourse facilitated by the clinician. Clinicians have a duty of care for the adequacy of women's knowledge, which can only be fulfilled when relevant knowledge is offered freely and when personal beliefs and biases that may impinge on decision-making (defeaters) are disclosed. Informed consent is not shared decision-making. Key barriers include existing cultural norms of “the doctor knows best” and “patient acquiescence” that prevent defeaters being acknowledged and discussed and can lead to legal challenges, overuse of medical intervention and, in some areas, obstetric violence. Shared decision-making in maternity care can thus be defined as an enquiry by clinician and expectant woman aimed at deciding upon a course of care or none, which takes the form of a dialogue within which the clinician fulfils their duty of care to the client's knowledge by making available their complete knowledge (based on all types of evidence) and expertise, including an exposition of any relevant and recognized potential defeaters. Research to develop measurement tools is required. (shrink)

In recent years there has been an explosion of interest in Artificial Intelligence (AI) both in health care and academic philosophy. This has been due mainly to the rise of effective machine learning and deep learning algorithms, together with increases in data collection and processing power, which have made rapid progress in many areas. However, use of this technology has brought with it philosophical issues and practical problems, in particular, epistemic and ethical. In this paper the authors, with backgrounds in (...) philosophy, maternity care practice and clinical research, draw upon and extend a recent framework for shared decision-making (SDM) that identified a duty of care to the client's knowledge as a necessary condition for SDM. This duty entails the responsibility to acknowledge and overcome epistemic defeaters. This framework is applied to the use of AI in maternity care, in particular, the use of machine learning and deep learning technology to attempt to enhance electronic fetal monitoring (EFM). In doing so, various sub-kinds of epistemic defeater, namely, transparent, opaque, underdetermined, and inherited defeaters are taxonomized and discussed. The authors argue that, although effective current or future AI-enhanced EFM may impose an epistemic obligation on the part of clinicians to rely on such systems' predictions or diagnoses as input to SDM, such obligations may be overridden by inherited defeaters, caused by a form of algorithmic bias. The existence of inherited defeaters implies that the duty of care to the client's knowledge extends to any situation in which a clinician (or anyone else) is involved in producing training data for a system that will be used in SDM. Any future AI must be capable of assessing women individually, taking into account a wide range of factors including women's preferences, to provide a holistic range of evidence for clinical decision-making.

This paper discusses knowledge of opposites. In particular, attention is given to the linguistic notion of antonymy and how it represents oppositional relations that are commonly found in perception. The paper draws upon the long history of work on the formalisation of antonymy in linguistics and formal semantics, and also upon work on the perception of opposites in psychology, and an assessment is made of the main approaches. Treatments of these phenomena in linguistics and psychology posit that the principles of (...) minimal difference and invariance are centrally important. It will be suggested that the standard approach employing meaning postulates fails to capture the relevant notion of antonymy, in part because it is not informed by these principles, and in part due to a number of other problems with this kind of approach, many of which may be overcome by building in the central principles from the beginning. The paper also discusses the issue of whether we can know that opposites necessarily exclude each other and, if so, how. This issue is intertwined with what is known as the colour incompatibility problem that Wittgenstein wrangled with at various times during his life. The paper assesses various solutions to these problems including an approach that was first put forward by Jerrold J. Katz. The relation between this approach and the theory of determinables and determinates is also examined. A further development upon this approach is proposed and then applied to the case of the formalisation of antonymy. It is argued that this approach avoids the problems suffered by the main approaches discussed earlier in the paper. (shrink)

This article investigates the clothing metaphor in Wittgenstein’s Tractatus Logico-Philosophicus at remark 4.002. I consider the antecedents and origins of 4.002, in particular, of the fourth paragraph that contains the metaphor, and also suggest and argue for potential source texts for the third and fourth paragraphs. In particular, early sources for the Tractatus, such as the Notes on Logic and the Notebooks 1914–1916, letters, and other manuscripts and early drafts are considered, especially MS104 and the Prototractatus where the metaphor appears (...) at remarks 4.0014 & 4.00141. The place of the metaphor among the context of the elucidations of these early manuscripts is discussed. I also consider similar uses of the metaphor that are present in the work of Hertz, Boltzmann, Frege, Kraus, and others. Some of these texts and potential influences are more compelling than those previously adduced or recognised in the literature. The appearances of the metaphor in the work of these authors and their potential influence upon Wittgenstein’s work is discussed. (shrink)

This book has been ably reviewed by others. I am taking a second look at it now on the occasion of the publication of its sequel, a review of which I also provide in this volume. I have had the distinct pleasure of being a student and colleague of Vasilis Politis (VP) since the initiation of the project that led to these monographs, and the great privilege of witnessing the development of the project for more than a decade. VP’s Plato (...) is in a way the only one I have known. When I hear the terms ‘aporia’, ‘whether-or-not’, and ‘ti esti’, they ring in my ears like bells. In this double review, I hope to impress upon the reader the unique importance of this interpretation of Plato, both for the history of philosophy and philosophy more broadly, and thereby to give a sense of its melody and resonance.

The edited volume will be of interest to philosophers and linguists working on the foundations of linguistics. It also contains material regarding some recent technical applications of realist frameworks in semantics, phonology, and morphology. The volume is derived from the proceedings of a workshop convened by the editors, Christina Behme and Martin Neef, on the theme ‘The Foundations of Linguistics: Languages as Abstract Objects’, at Technische Universität Braunschweig, in June 2015. The editors claim that “The workshop was the first scientific (...) event ever that was exclusively devoted to the topic of Linguistic Realism” (p. xi). The volume (pp. xiii + 296) consists of an introduction by the editors and eleven chapters of varying lengths contributed by philosophers and linguists, some of whom have been working in the field for over fifty years.

In this book, VP builds upon his previous study by shifting focus from the motivation for the ti esti question, to the motivation for the commitment to what is designated by an adequate and true answer to such questions. VP’s aim in this study is to show that what are usually called ‘Forms’ (eidē), rather than being things that have essences, simply are those essences designated by adequate and true answers to ti esti questions. This book is highly recommended for (...) scholars, students, and anyone wishing to understand the core of Plato’s philosophy and its motivations from the ground upwards. (shrink)

This book represents more than a decade of work (p. ix) by this eminent scholar. It is intended primarily for scholars of Classical Greek; however, F.’s laudable practice of, in most cases, providing English translations and repeating them when needed, makes it accessible to non-specialists and undergraduates, as he intended (pp. ix–x).
