Realists, D. M. Armstrong among them, claim, contrary to natural class nominalists, that natural classes are analysable. Natural classes of particulars, claim the realists, can be analysed in terms of particulars having universals in common. But for the realist, there are also natural classes of universals. And if the realist's claim that natural classes are analysable is a general claim about natural classes, then the realist must also provide an analysis of natural classes of universals. For Armstrong, the unity (or (...) naturalness) of a natural class of universals is analysed in terms of universals resembling each other. I argue that Armstrong's account fails. His account fails for the same reason all other resemblance accounts of natural classes fail: some arbitrary classes satisfy the analysis for natural classes. (shrink)

Responds to the idea that humans are merely survival mechanisms for their own genes, providing the tools to advance human interests over the interests of the replicators through rational self-determination.

Well before the COVID-19 pandemic, proponents of digital psychiatry were touting the promise of various digital tools and techniques to revolutionize mental healthcare. As social distancing and its knock-on effects have strained existing mental health infrastructures, calls have grown louder for implementing various digital mental health solutions at scale. Decisions made today will shape the future of mental healthcare for the foreseeable future. We argue that bioethicists are uniquely positioned to cut through the hype surrounding digital mental health, which can (...) obscure crucial ethical and epistemic gaps that ought to be considered by policymakers before committing to a digital psychiatric future. Here, we describe four such gaps: The evidence gap, the inequality gap, the prediction-intervention gap, and the safety gap. (shrink)

This book examines the politics of diversity, and explores potential sources of support for an inclusive solidarity, in particular political sources of solidarity.

This book aims to provide a solution to the semantic paradoxes. It argues for a unified solution to the paradoxes generated by our concepts of denotation, predicate extension, and truth. The solution makes two main claims. The first is that our semantic expressions 'denotes', 'extension' and 'true' are context-sensitive. The second, inspired by a brief, tantalizing remark of Godel's, is that these expressions are significant everywhere except for certain singularities, in analogy with division by zero. A formal theory of singularities (...) is presented and applied to a wide variety of versions of the definability paradoxes, Russell's paradox, and the Liar paradox. Keith Simmons argues that the singularity theory satisfies the following desiderata: it recognizes that the proper setting of the semantic paradoxes is natural language, not regimented formal languages; it minimizes any revision to our semantic concepts; it respects as far as possible Tarski's intuition that natural languages are universal; it responds adequately to the threat of revenge paradoxes; and it preserves classical logic and semantics. Simmons draws out the consequences of the singularity theory for deflationary views of our semantic concepts, and concludes that if we accept the singularity theory, we must reject deflationism.

Interpretation is the process whereby a hearer reasons to an interpretation of a speaker's discourse. The hearer normally adopts a credulous attitude to the discourse, at least for the purposes of interpreting it. That is to say the hearer tries to accommodate the truth of all the speaker's utterances in deriving an intended model. We present a nonmonotonic logical model of this process which defines unique minimal preferred models and efficiently simulates a kind of closed-world reasoning of particular interest for (...) human cognition. Byrne's “suppression” data (Byrne, 1989) are used to illustrate how variants on this logic can capture and motivate subtly different interpretative stances which different subjects adopt, thus indicating where more fine-grained empirical data are required to understand what subjects are doing in this task. We then show that this logical competence model can be implemented in spreading activation network models. A one pass process interprets the textual input by constructing a network which then computes minimal preferred models for (3-valued) valuations of the set of propositions of the text. The neural implementation distinguishes easy forward reasoning from more complex backward reasoning in a way that may be useful in explaining directionality in human reasoning. (shrink)

Colours appear to instantiate a number of structural properties: for instance, they stand in distinctive relations of similarity and difference, and admit of a fundamental distinction into unique and binary. Accounting for these structural properties is often taken to present a serious problem for physicalist theories of colour. This paper argues that a prominent attempt by Byrne and Hilbert to account for the structural properties of the colours, consistent with the claim that colours are types of surface spectral reflectance, is (...) unsuccessful. Instead, it is suggested that a better account of the structural properties of the colours is provided by a form of non-reductive physicalism about colour: a naïve realist theory of colour, according to which colours are superficial mind-independent properties.

Continuing Keith Ward's series on comparative religion, this book deals with religious views of human nature and destiny. The beliefs of six major traditions are presented: the view of Advaita Vedanta that there is one Supreme Self, unfolding into the illusion of individual existence; the Vaishnava belief that there is an infinite number of souls, whose destiny is to be released from material embodiment; the Buddhist view that there is no eternal Self; the Abrahamic belief that persons are essentially (...) embodied souls; and the materialistic position that persons are complex material organisms. Indian ideas of rebirth, karma, and liberation from samsara are critically analysed and compared with semitic belief in the intermediate state of Sheol, Purgatory or Paradise, the Final Judgement and the resurrection of the body. The impact of scientific theories of cosmic and biological evolution on religious beliefs is assessed, and a form of 'soft emergent materialism' is defended, with regard to the soul. In this context, a Christian doctrine of original sin and atonement is presented, stressing the idea of soterial, as opposed to forensic, justice. Finally, a Christian view of personal immortality and the 'end of all things' is developed in conversation with Jewish and Muslim beliefs about judgement and resurrection. (shrink)

Rubin and Pearl offered approaches to causal effect estimation and Lewis and Pearl offered theories of counterfactual conditionals. Arguments offered by Pearl and his collaborators support a weak form of equivalence such that notation from the rival theory can be re-purposed to express Pearl’s theory in a way that is equivalent to Pearl’s theory expressed in its native notation. Nonetheless, the many fundamental differences between the theories rule out any stronger form of equivalence. A renewed emphasis on comparative research can (...) help to guide applications, further develop each theory, and better understand their relative strengths and weaknesses. (shrink)

Condorcet's understanding of the application of the philosophy of natural sceince to social science.

Does the increasing politicization of ethnic and racial diversity of Western societies threaten to undermine the welfare state? This volume is the first systematic attempt to explore this linkage between "the politics of recognition" and "the politics of redistribution".

The concept of the 'social Trinity', which posits three conscious subjects in God, radically revised the traditional Christian idea of the Creator. It promoted a view of God as a passionate, creative and responsive source of all being. Keith Ward argues that social Trinitarian thinking threatens the unity of God, however, and that this new view of God does not require a 'social' component. Expanding on the work of theologians such as Barth and Rahner, who insisted that there was (...) only one mind of God, Ward offers a coherent, wholly monotheistic interpretation of the Trinity. Christ and the Cosmos analyses theistic belief in a scientific context, demonstrating the necessity of cosmology to theological thinking that is often overly myopic and anthropomorphic. This important volume will benefit those who seek to understand what the Trinity is, why it matters and how it fits into a scientific account of the universe. (shrink)

In metaphysics, we seem to have in every generation an oscillation between realist positions and stances that are in one way or another idealist, instrumentalist, or constructivist. Realists in the philosophy of science are those philosophers who will not conclude, from the fact that scientific theories are undoubtedly constructs of human mentality and culture, that therefore the content of these theories is inevitably some function of the human mentality and culture that have produced them. Realists are unimpressed by response-dependence. Realism (...) is metaphysical optimism; it has not abandoned the notion that exercising our capacities does not disqualify us from discovery.

Objects appear different as the illumination under which they are perceived varies. This fact is sometimes thought to pose a problem for the view that colours are mind-independent properties: if a coloured object appears different under different illuminations, then under which illumination does the object appear the colour it really is? I argue that given the nature of natural daylight, and certain plausible assumptions about the nature of the colours it illuminates, there is a non-arbitrary reason to suppose that it (...) is under natural daylight that we are able to perceive the real colours of objects.

The “Adam Smith Problem” is the name given to an argument that arose among German scholars during the second half of the nineteenth century concerning the compatibility of the conceptions of human nature advanced in, respectively, Adam Smith's Theory of Moral Sentiments (1759) and his Wealth of Nations (1776). During the twentieth century these arguments were forgotten but the problem lived on, the consensus now being that there is no such incompatibility, and therefore no problem. Rather than rehearse the arguments (...) for and against compatibility and incompatibility, this paper returns to the German writers of the 1850s–1890s and demonstrates that their engagement in this argument represents the foundation of modern Smith scholarship. It is shown that the “problem” was not simply a mistake best forgotten, but the first sustained scholarly effort to understand the importance of Smith's work, an effort that lacked any parallel in English commentary of the time. By the 1890s British writers, overwhelmingly ignorant of German commentary, assumed that there was little more to be said about Smith's work. Belated international familiarity with this German “Problem” played a major role in transforming Smith from a simple partisan of free trade into a theorist of commercial society and human action. ☆ This paper was presented at the annual meeting of the Dogmenhistorischer Auschuss of the Verein für Sozialpolitik, Lüdinghausen, June 2007. I would like to thank all those attending for their very helpful comments. In places I here draw upon material included in my essays on the Smith reception in A Critical Bibliography of Adam Smith (edited by Keith Tribe, with Hiroshi Mizuta), Pickering and Chatto, London 2002, but do so in order to make a new argument concerning the contribution of German scholarship to modern Adam Smith scholarship.

Courts are increasingly obliged to adjudicate upon challenges to allocative decisions in healthcare, but their involvement continues to be regarded with unease, imperilling the legitimacy of the judicial role in this context. A central reason for this is that judges are perceived to lack sufficient expertise to determine allocative questions. This article critically appraises the claim of lack of judicial expertise through an examination of the various components of a limit-setting decision. It is argued that the inexpertise argument is weak (...) when compared with other rationales for judicial restraint, such as the procedural unsuitability and lack of constitutional competence of courts.

Transposable elements (TEs) are powerful facilitators of genome evolution, and hence of phenotypic diversity as they can cause genetic changes of great magnitude and variety. TEs are ubiquitous and extremely ancient, and although harmful to some individuals, they can be very beneficial to lineages. TEs can build, sculpt, and reformat genomes by both active and passive means. Lineages with active TEs or with abundant homogeneous inactive populations of TEs that can act passively by causing ectopic recombination are potentially fecund, adaptable, (...) and taxonate readily. Conversely, taxa deficient in TEs or possessing heterogeneous populations of inactive TEs may be well adapted in their niche, but tend to prolonged stasis and may risk extinction by lacking the capacity to adapt to change, or diversify. Because of recurring intermittent waves of TE infestation, available data indicate a compatibility with punctuated equilibrium, in keeping with widely accepted interpretations of evidence from the fossil record. We propose a general and holistic synthesis on how the presence of TEs within genomes makes them flexible and dynamic, so that genomes themselves are powerful facilitators of their own evolution.

Executive function has become an important concept in explanations of psychiatric disorders, but we currently lack comprehensive models of normal executive function and of its malfunctions. Here we illustrate how defeasible logical analysis can aid progress in this area. We illustrate using autism and attention deficit hyperactivity disorder (ADHD) as example disorders, and show how logical analysis reveals commonalities between linguistic and non-linguistic behaviours within each disorder, and how contrasting sub-components of executive function are involved across disorders. This analysis reveals (...) how logical analysis is as applicable to fast, automatic and unconscious reasoning as it is to slow deliberate cogitation. (shrink)

A successful lexicographic semantic description characterizes the concepts that occur in establishing the meaning of a listeme by modelling what the competent native-like speaker of the language knows. Because concepts can only be identified to another human through the medium of a natural language, the metalanguage used in the semantic definition of a natural language expression in the object language will always be equivalent to the natural language expression through which that metalanguage is interpreted. The metalanguage of a semantic theory (...) is a demonstrably rational abstract model developed by applying the analyst’s experience and intuitions to inferences drawn from occurrences of actual speech events. Each sense of a listeme is characterized by a description of the salient properties of its typical denotatum. To most effectively implement this project in conceptual engineering is to capture every possible sense of the listeme using metalanguage that is at the same time precise, comprehensive, and succinct. A review of several proposed lexicon/dictionary entries for the listeme cup reveals lacunae that are rectified in a decision procedure whose output characterizes the relevant sense of the input listeme using natural language and the procedural constructs/commands &, XOR, IF, ELSE, ELIF, GOTO, OUTPUT, TENABLE, NEXT ITEM. The resulting lexicographic semantic description satisfies the specified success condition. Establishing the characteristics of metalanguage is crucial to the proper investigation of conceptual engineering. (shrink)

In understanding the degree of choice we have in our emotions, we benefit from the Stoics’ analysis into first and second movements: appraisals and reappraisals. The Stoics were concerned to avoid the harm that emotions can cause, but their idea of working on goals, rather than on emotions as such, generalizes beyond their concerns. For modern people, the problem of taking responsibility for our emotional life becomes less paradoxical when we consider interpersonal issues.

This paper considers whether we should believe philosophical claims on the basis of testimony in light of related debates about aesthetic and moral testimony. It is argued that we should not believe philosophical claims on testimony, and different explanations of why we should not are considered. It is suggested that the reason why we should not believe philosophical claims on testimony might be that philosophy is not truth-directed.

Why History? is a compelling introduction to the issue of history and ethics. Designed to provoke discussion, the book asks whether and why a good knowledge and understanding of the past is desirable. In the context of current postmodern thinking, Keith Jenkins suggests that the goal of "learning lessons from the past" actually means learning lessons from stories written by historians and others. If the past as history has no foundation, can anything ethical be gained from history? Daring and (...) controversial, Why History? presents liberating challenges to history and ethics, proposing that we have reached an emancipatory moment which is well beyond the "end of history.".

Locke’s argument for the primary-secondary quality distinction is compared with Descartes’s argument (in the Principles of Philosophy) for the distinction between mechanical modifications and sensible qualities. I argue that following Descartes, Locke’s argument for the primary-secondary quality distinction is an essentially a priori argument, based on our conception of substance, and the constraints on intelligible bodily interaction that this conception of substance sets.

The subject of religious diversity is of growing significance, with its associated problems of religious pluralism and inter-faith dialogue. Moreover, since the European Enlightenment, religions have had to face new, existential challenges. Is there a future for religions? How will they have to change? Can they co-exist peacefully? In this book, Keith Ward brings new insights to these questions. Applying historical and philosophical approaches, he explores how we can establish truth among so many diverse religions. He explains how religions (...) have evolved over time and how they are reacting to the challenges posed by new scientific and moral beliefs. A celebration of the diversity in the world's religions, Ward's timely book also deals with the possibility and necessity of religious tolerance and co-existence. (shrink)

Review of Larry Arnhart, ‘Darwinian Natural Right: The Biological Ethics of Human Nature’, plus response from Larry Arnhart.

The vision of global health with justice which Larry Gostin articulates in his book Global Health Law envisages a switch to ‘upstream’ priority-setting for expenditure on health, with a focus upon social determinants and a goal of redressing health inequalities. This article explores what is meant by this proposal and offers a critical evaluation of it. It is argued that difficulties arise in respect of the ethical and evidential bases for such an approach to the setting of priorities, while significant (...) challenges may also arise in the necessary modification of structures of governance.
