The measurement of force is based on a formal law of additivity, which characterizes the effects of two or more configurations on the equilibrium of a material point. The representing vectors (resultant forces) are additive over configurations. The existence of a tight interrelation between the force vector and the geometric space, in which motion is described, depends on observations of partial (directional) equilibria; an axiomatization of this interrelation yields a proof of part two of Newton's second law of motion. The (...) present results (which were derived from a curious and deep isomorphism between force measurement and trichromatic color measurement) yield a kind of subunit, which needs to be incorporated into more complete axiomatizations of mechanics that would fulfill the Mach-Kirchhoff program.

We use a sequential voluntary contribution game to compare the relative impact of a first-mover’s non-binding announcement versus binding commitment on cooperation. We find that a non-binding announcement and a binding commitment increase individual contributions to a similar extent. Since announced contributions systematically exceed commitments, in sessions with a non-binding announcement, second-movers tend to contribute more to the group activity than in sessions with a binding commitment. Yet, second-movers appear to be more motivated towards achieving a social optimum when the (...) first-mover uses commitment. We also find that a non-binding announcement has a higher impact on individual propensity to cooperate than the ex post contribution of the first-mover. However, the failure to make announced contributions decreases cooperation even though the first-mover is reassigned in every period. (shrink)

De Neys argues against assigning exclusive capacities to automatic versus controlled processes. The dual implicit process model provides a theoretical rationale for the exclusivity of automatic threat processing, and corresponding data provide empirical evidence of such exclusivity. De Neys's dismissal of exclusivity is premature and based on a limited sampling of psychological research.

_Real Essentialism_ presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. _Real Essentialism_ reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability (...) of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

"Nivison brings out the exciting variety within Confucian thought, as he interprets and elucidates key thinkers from over two thousand years, from Confucius himself, through Mencius and Xunzi, to such later Confucians as Wang Yangming, Dai Zhen, and Zhang Xuecheng."--Cover.

The distinction between the essence of an object and its properties has been obscured in contemporary discussion of essentialism. Locke held that the properties of an object are exclusively those features that ‘flow’ from its essence. Here he follows the Aristotelian theory, leaving aside Locke’s own scepticism about the knowability of essence. I defend the need to distinguish sharply between essence and properties, arguing that essence must be given by form and that properties flow from form. I give a precise (...) definition of what the term of art ‘flow’ amounts to, and apply the distinction to various kinds of taxonomic issues. (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)

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

This paper tests the following hypothesis: that the prime matter of classical Aristotelian-Scholastic metaphysics is numerically identical to energy. Is P=E? After outlining the classical Aristotelian concept of prime matter, I provide the master argument for it based on the phenomenon of substantial change. I then outline what we know about energy as a scientific concept, including its role and application in some key fields. Next, I consider the arguments in favour of prime matter being identical to energy, followed by (...) the arguments against. The method used is that of ontological profile comparison: does the profile of prime matter match, in key features, that of energy? An affirmative answer, that P=E, would be a momentous discovery: it would show that one of the most neglected and derided ideas of pre-modern metaphysics – a contributor to its downfall in the wake of the Scientific Revolution – was right all along. From a negative answer we would still learn much about the interaction of science and metaphysics. It turns out, however, given what we currently know, that the answer is not quite as simple as one might hope. (shrink)

Proponents of physical intentionality argue that the classic hallmarks of intentionality highlighted by Brentano are also found in purely physical powers. Critics worry that this idea is metaphysically obscure at best, and at worst leads to panpsychism or animism. I examine the debate in detail, finding both confusion and illumination in the physical intentionalist thesis. Analysing a number of the canonical features of intentionality, I show that they all point to one overarching phenomenon of which both the mental and the (...) physical are kinds, namely finality. This is the finality of ‘final causes’, the long-discarded idea of universal action for an end to which recent proponents of physical intentionality are in fact pointing whether or not they realise it. I explain finality in terms of the concept of specific indifference, arguing that in the case of the mental, specific indifference is realised by the process of abstraction, which has no correlate in the case of physical powers. This analysis, I conclude, reveals both the strength and weakness of rational creatures such as us, as well as demystifying the way in which powers work. (shrink)

Applied Ethics focuses the central concepts of traditional morality from the companion book Moral Theory - rights, justice, the good, virtue, and the fundamental value of human life - on a number of pressing contemporary problems, including abortion, euthanasia, animals, capital punishment, and war.

The Dead Donor Rule holds that removing organs from a living human being without their consent is wrongful killing. The rule still prevails in most countries, and I assume it without argument in order to pose the question: is it possible to have a metaphysically correct, clinically relevant analysis of human death that makes organ donation possible? I argue that the two dominant criteria of death, brain death and circulatory death, are both empirically and metaphysically inadequate as definitions of human (...) death, and therefore of no epistemic value in themselves. I first set out a neo-Aristotelian theory of death as separation of soul (understood as organising principle) and body, which is then fleshed out as loss of organismic integrity. The brain and circulatory criteria are shown to have severe weaknesses as physiological manifestations of loss of integrity. Given the mismatch between what death is metaphysically speaking, and the dominant criteria accepted by clinicians and philosophers, it turns out that only actual bodily decomposition is a sure sign of death. In this I differ from Alan Shewmon, whose important work I discuss in detail. (shrink)

The old scholastic principle of the "convertibility" of being and goodness strikes nearly all moderns as either barely comprehensible or plain false. "Convertible" is a term of art meaning "interchangeable" in respect of predication, where the predicates can be exchanged salva veritate albeit not salva sensu: their referents are, as the maxim goes, really the same albeit conceptually different. The principle seems, at first blush, absurd. Did the scholastics literally mean that every being is good? Is that supposed to include (...) a cancer, a malaria parasite, an earthquake that kills millions? If every being is good, then no being is bad—but how can that be? To the contemporary philosophical mind, such bafflement is understandable. It derives from the systematic dismantling of the great scholastic edifice that took place over half a millennium. With the loss of the basic concepts out of which that edifice was built, the space created by those concepts faded out of existence as well. The convertibility principle, like virtually all the other scholastic principles (not all, since some do survive and thrive in analytic philosophy), could not persist in a post-scholastic space wholly alien to it.

I explore the increasingly important issue of cooperation in immoral actions, particularly in connection with healthcare. Conscientious objection, especially as pertains to religious freedom in healthcare, has become a pressing issue in the light of the US Supreme Court judgement inHobby Lobby. Section ‘Moral evaluation using the basic principles of cooperation’ outlines a theory of cooperation inspired by Catholic moral theologians such as those cited by the court. The theory has independent plausibility and is at least worthy of serious consideration—in (...) part because it is an instance of double-effect reasoning, which is also independently plausible despite its association with moral theology. Section ‘Case study:Burwell v. Hobby Lobby’ examinesHobby Lobbyin detail. Even if the judgement was correct in that case the reasoning was not, as it involved applying a ‘mere sincerity’ test to the cooperation question. The mere sincerity test leads to absurd consequences, whereas a reasonableness test applied using the theory of cooperation defended here would avoid absurdity. Section ‘A question of remoteness: “accommodations” and opt-outs’ explores the post-Hobby Lobbyproblem further, examining opt-outs and accommodations: theLittle Sisters of the Poorcase shows how opt-outs are misunderstood on a mere sincerity test, which the court rightly rejected. Section 'Application to the medical field:Doogan and Wood’ discusses the UK case ofDoogan and Wood, concerning participation in abortion. Again, a judicially recognised ethic of cooperation, if it were part of the fabric of legal reasoning in such cases, would have enabled the conscientious objectors in this and similar situations to have their freedom of conscience and religion respected in a way that it currently is not.

Corruptionism is the view that following physical death, the human being ceases to exist but their soul persists in the afterlife. Survivalism holds that both the human being and their soul persist in the afterlife, as distinct entities, with the soul constituting the human. Each position has its defenders, most of whom appeal both to metaphysical considerations and to the authority of St Thomas Aquinas. Corruptionists claim that survivalism violates a basic principle of any plausible mereology, while survivalists tend to (...) reject the principle, though without as much detail as one would like. In this paper I examine both the key exegetical issues and the mereological question, arguing that Aquinas cannot be shown to have supported the principle in question, and that the principle should be rejected on independent grounds. If correct, some key planks in support of survivalism are established, with others to await further examination. (shrink)

_Moral Theory_ sets out the basic system used to solve moral problems, the system that consequentialists deride as 'traditional morality'.

Whereas Mereological Essentialism is the thesis that the parts of an object are essential to it, Reverse Mereological Essentialism is the thesis that the whole is essential to its parts. Specifically – since RME is an Aristotelian doctrine – it is a claim not about objects in general but about substances. Here I set out and explain RME as it should be understood from the perspective of the Aristotelian-Scholastic tradition, as well as proposing a kind of master argument for believing (...) it. A number of objections (many of which have been raised by Kathrin Koslicki or Robert Koons) are then considered, the replies to which help further to clarify and motivate RME. The final section considers some important questions concerning parts and matter in light of Ross Inman’s recent defence of RME under the guise of what he calls Substantial Priority. Considering these questions further illustrates right and wrong ways of understanding RME. Overall, the case for RME is strong albeit with a number of difficulties that need to be resolved through further investigation. (shrink)

We live in a liberal, pluralistic, largely secular society where, in theory, there is fundamental protection for freedom of conscience generally and freedom of religion in particular. There is, however, both in statute and common law, increasing pressure on religious believers and conscientious objectors to act in ways that violate their sincere, deeply held beliefs. This is particularly so in health care, where conscientious objection is coming under extreme pressure. I argue that freedom of religion and conscience need to be (...) put on a sounder footing both legislatively and by the courts, particularly in health care. I examine a number of important legal cases in the UK and US, where freedom of religion and conscience have come into conflict with government mandates or equality and anti-discrimination law. In these and other cases we find one of two results: either the conscientious objector loses out against competing rights, or the conscientious objector succeeds, but due to what I consider unsound judicial reasoning. In particular, cases involving cooperation in what the objector considers morally impermissible according to their beliefs have been wrongly understood by some American courts. I argue that a reasonable theory of cooperation incorporated into judicial thinking would enable more acceptable results that gave sufficient protection to conscientious objectors without risking a judicial backlash against objectors who wanted to take their freedoms too far. I also venture into broader, more controversial waters concerning what I call freedom of dissociation – the fundamental right to withdraw from associating with people, groups, and activities. It is no more than the converse of freedom of association, which all free societies recognise as a basic right. How far should freedom of dissociation go? What might society be like if freedom of dissociation were given more protection in law than it currently has? It would certainly give freedom of religion and conscience a substantial foundation, but it could also lead to discriminatory behaviour to which many people would object. I explore some of these issues, before going back to the narrower area of freedom of conscience and religion in health care, making some proposals about how the law could strengthen these basic pillars of a liberal, free society.

As machine learning has gradually entered into ever more sectors of public and private life, there has been a growing demand for algorithmic explainability. How can we make the predictions of complex statistical models more intelligible to end users? A subdiscipline of computer science known as interpretable machine learning (IML) has emerged to address this urgent question. Numerous influential methods have been proposed, from local linear approximations to rule lists and counterfactuals. In this article, I highlight three conceptual challenges that (...) are largely overlooked by authors in this area. I argue that the vast majority of IML algorithms are plagued by (1) ambiguity with respect to their true target; (2) a disregard for error rates and severe testing; and (3) an emphasis on product over process. Each point is developed at length, drawing on relevant debates in epistemology and philosophy of science. Examples and counterexamples from IML are considered, demonstrating how failure to acknowledge these problems can result in counterintuitive and potentially misleading explanations. Without greater care for the conceptual foundations of IML, future work in this area is doomed to repeat the same mistakes. (shrink)

abstract This paper re‐examines some well‐known and commonly accepted arguments for the non‐individuality of the embryo, due mainly to the work of John Harris. The first concerns the alleged non‐differentiation of the embryoblast from the trophoblast. The second concerns monozygotic twinning and the relevance of the primitive streak. The third concerns the totipotency of the cells of the early embryo. I argue that on a proper analysis of both the empirical facts of embryological development, and the metaphysical importance or otherwise (...) of those facts, all three arguments are found wanting. None of them establishes that the embryo is not an individual human being from the moment of conception. (shrink)

Things change. If anything counts as a datum of metaphysics, that does. Change occurs in many ways: it can be accidental or substantial; essential or non-essential; intrinsic or extrinsic; subjective or objective. Changes can be physical, spatial, quantitative, qualitative, natural, artefactual, conceptual, linguistic. Events are arguably best defined as changes in an object or objects. All change is from something and into something, and hence is at least a two-term relation, involving a term from which and a term to which.

Contemporary liberal societies are seeing increasing pressure on individuals to act against their consciences. Most of the pressure is directed at freedom of religion but it also affects ethical beliefs more generally, contrary to the recognition of freedom of religion and conscience as a basic human right. I propose that freedom of dissociation, as a corollary of freedom of association, could be a practical and ethically acceptable solution to the conscience problem. I examine freedom of association and explain how freedom (...) of dissociation follows from it, showing how dissociation protects freedom of religion and conscience. Extreme cases, such as the problem of the Satanist nurse, can be handled within a dissociationist framework, so it is reasonable to think less extreme cases can also be dealt with. The serious objection that dissociationism entails unjust discrimination is answered primarily by appeal to the need for ‘full and fair access’ to goods and services by all groups. I then allay important concerns about what kind of liberal society we should want to live in. Next, I refute the charge that a dissociationist society violates liberalism's ‘higher good’, arguing that liberalism strictly does not have a higher good. I conclude with some reflections on what a dissociationist society might look like. (shrink)

The Guise of the Good thesis has received much attention since Anscombe's brief defence in her book Intention. I approach it here from a less common perspective - indirectly, via a theory explaining how it is that moral behaviour is even possible. After setting out how morality requires the employment of a fundamental test, I argue that moral behaviour involves orientation toward the good. Immoral behaviour cannot, however, involve orientation to evil as such, given the theory of evil as privation. (...) There must always be orientation to good of some kind for immorality even to be possible. Evil can, nevertheless, be intended, but this must be carefully understood in terms of the metaphysic of good and evil I set out. Given that metaphysic, the Guise of the Good is a virtual corollary.

The Metaphysics of Good and Evil is the first, full-length contemporary defence, from the perspective of analytic philosophy, of the Scholastic theory of good and evil - the theory of Aristotle, Augustine, Aquinas, and most medieval and Thomistic philosophers. Goodness is analysed as obedience to nature. Evil is analysed as the privation of goodness. Goodness, surprisingly, is found in the non-living world, but in the living world it takes on a special character. The book analyses various kinds of goodness, showing (...) how they fit into the Scholastic theory. The privation theory of evil is given its most comprehensive contemporary defence, including an account of truthmakers for truths of privation and an analysis of how causation by privation should be understood. In the end, all evil is deviance - a departure from the goodness prescribed by a thing's essential nature. Key Features: Offers a comprehensive defence of a venerable metaphysical theory, conducted using the concepts and methods of analytic philosophy. Revives a much neglected approach to the question of good and evil in their most general nature. Shows how Aristotelian-Thomistic theory has more than historical relevance to a fundamental philosophical issue, but can be applied in a way that is both defensible and yet accessible to the modern philosopher. Provides what, for the Scholastic philosopher, is arguably the only solid metaphysical foundation for a separate treatment of the origins of morality. (shrink)

It investigates both the external formal and internal cognitive parallels between the axioms, intuitions and constructions of geometry and the scientific methodology of the Fichtean system of philosophy.
