This volume presents a collection of refereed papers reflecting the state of the art in the area of over-constrained systems. Besides 11 revised full papers, selected from the 24 submissions to the OCS workshop held in conjunction with the First International Conference on Principles and Practice of Constraint Programming, CP '95, held in Marseilles in September 1995, the book includes three comprehensive background papers of central importance for the workshop papers and the whole field. Also included is an introduction (...) by one of the volume editors together with a bibliography listing 243 entries. All in all this is a very useful reference book relevant for all researchers and practitioners interested in hierarchical, partial, and over-constrained systems. (shrink)

Book reviewed in this article: Principles of Biomedical Ethics. By Tom L. Beauchamp and James F. Childress.

Guiding principles are central to theory development in physics, especially when there is only limited empirical input available. Here I propose an approach to such principles looking at their heuristic role. I suggest a distinction between two modes of employing scientific principles. Principles of nature make descriptive claims about objects of inquiry, and principles of epistemic action give directives for further research. If a principle is employed as a guiding principle, then its use integrates both (...) modes of employment: guiding principles imply descriptive claims, and they provide directives for further research. By discussing the correspondence principle and the naturalness principle as examples, I explore the consequences for understanding and evaluating current guiding principles in physics. Like principles of nature, guiding principles are evaluated regarding their descriptive implications about the research object. Like principles of epistemic action, guiding principles are evaluated regarding their ability to respond to context-specific needs of the epistemic agent. (shrink)

Allocation of very scarce medical interventions such as organs and vaccines is a persistent ethical challenge. We evaluate eight simple allocation principles that can be classified into four categories: treating people equally, favouring the worst-off, maximising total benefits, and promoting and rewarding social usefulness. No single principle is sufficient to incorporate all morally relevant considerations and therefore individual principles must be combined into multiprinciple allocation systems. We evaluate three systems: the United Network for Organ Sharing points systems, quality-adjusted (...) life-years, and disability-adjusted life-years. We recommend an alternative system—the complete lives system—which prioritises younger people who have not yet lived a complete life, and also incorporates prognosis, save the most lives, lottery, and instrumental value principles.

Moral philosophy has long been dominated by the aim of understanding morality and the virtues in terms of principles. However, the underlying assumption that this is the best approach has received almost no defence, and has been attacked by particularists, who argue that the traditional link between morality and principles is little more than an unwarranted prejudice. In Principled Ethics, Michael Ridge and Sean McKeever meet the particularist challenge head-on, and defend a distinctive view they call "generalism as (...) a regulative ideal.". (shrink)

According to the Principle of Sufficient Reason (henceforth ‘PSR’), everything has an explanation or sufficient reason. This paper addresses three questions. First, how continuous is the contemporary notion of grounding with the notion of sufficient reason endorsed by Spinoza, Leibniz, and other rationalists? In particular, does a PSR formulated in terms of ground retain the intuitive pull and power of the PSR endorsed by the rationalists? Second, to what extent can the PSR avoid the formidable traditional objections levelled against it (...) if it is formulated in terms of ground? And finally, how might historical discussion of the PSR shed light on the contemporary notion of grounding? (shrink)

Stephen Nathanson's clear-sighted abridgment of _Principles of Political Economy_, Mill's first major work in moral and political philosophy, provides a challenging, sometimes surprising account of Mill's views on many important topics: socialism, population, the status of women, the cultural bases of economic productivity, the causes and possible cures of poverty, the nature of property rights, taxation, and the legitimate functions of government. Nathanson cuts through the dated and less relevant sections of this large work and includes significant material omitted in (...) other editions, making it possible to see the connections between the views Mill expressed in _Principles of Political Economy_ and the ideas he defended in his later works, particularly _On Liberty_. Indeed, studying _Principles of Political Economy_, Nathanson argues in his general Introduction, can help to resolve the apparent contradiction between Mill's views in On Liberty and those in _Utilitarianism_, making it a key text for understanding Mill’s philosophy as a whole.

What is morally permissible, and what is morally obligatory? These questions form the core of a vast amount of philosophical reasoning. In his Fundamental Principles of the Metaphysics of Morals, Immanuel Kant developed a basis for the answers. In this landmark work, the German philosopher asks what sort of maxim might function as a guide to appropriate action under a given set of circumstances. By universalizing such a maxim, would morally permissible behavior not become clear? Suppose that everyone were (...) to behave in accordance with this maxim. If everyone followed the maxim in the same way without harm to civilized culture, then the behavior would be morally permissible. But what if no one followed the maxim? Would civilization thereby be at risk? In such a case, the behavior would be morally obligatory. Kant's test, known as the Categorical Imperative, is a logical proof of the Golden Rule and the centerpiece of this work. It constitutes his best-known contribution to ethical discussion, and a familiarity with his reasoning in this book is essential to students of philosophy, religion, and history. (shrink)

Research on human infants has begun to shed light on early-developing processes for segmenting perceptual arrays into objects. Infants appear to perceive objects by analyzing three-dimensional surface arrangements and motions. Their perception does not accord with a general tendency to maximize figural goodness or to attend to nonaccidental geometric relations in visual arrays. Object perception does accord with principles governing the motions of material bodies: Infants divide perceptual arrays into units that move as connected wholes, that move separately from (...) one another, that tend to maintain their size and shape over motion, and that tend to act upon each other only on contact. These findings suggest that o general representation of object unity and boundaries is interposed between representations of surfaces and representations of objects of familiar kinds. The processes that construct this representation may be related to processes of physical reasoning. (shrink)

Traditionally, T. M. Scanlon’s moral contractualism has been understood in terms of principle contractualism. In an earlier volume of this journal, however, Aaron Salomon argued that contractualists should shift their theory’s evaluative focal point away from principles in order to respond to the ideal world objection. After rejecting act contractualism as an alternative way of doing so, he suggested that contractualists should instead adopt a view he refers to as maxim contractualism. While I agree with Salomon that his suggestion (...) comes with important advantages, I argue in this discussion note that maxim contractualism cannot fully solve the problem that Salomon has raised against act contractualism. As a result, I conclude that contractualists should not be too quick in leaving principle contractualism behind. (shrink)

This book is devoted to the problems of the growth of science. These prob lems, neglected for a long time by the philosophers of science, have become in the 60's and 70's a subject of vivid discussion. There are philosophers who stress only the dependence of science upon various sociological, psycho logical and other factors and deny any internal laws of the development of knowledge, like approaching the truth. The majority rejects such nihilism and searches for the laws of the (...) growth of science. However, they often overlook the role of the Correspondence Principle which connects the suc cessive scientific theories. On the other hand, some authors, while stressing the role of this principle, overlook logical difficulties connected with it, e. g. the problem of the incompatibility of successive theories, of the falsity of some of their assumptions, etc. I believe the Correspondence Principle to be a basic principle of the pro gress of contemporary physics and, probably, of every advanced science. How ever, this principle must be properly interpreted and the above-mentioned logical difficulties must be solved. Their solution requires, as it seems, revealing the idealizational nature of the basic laws of science, in any case of the quantitative laws of advanced sciences. This point has been recently emphasized by some Polish philosophers, especially in Poznan. (shrink)

Peter van Inwagen presented a powerful argument against the Principle of Sufficient Reason, which I henceforth abbreviate as ‘PSR’. For decades, the consensus was that this argument successfully refuted PSR. However, now a growing consensus holds that van Inwagen’s argument is fatally flawed, at least when ‘sufficient reason’ is understood in terms of ground, for on this understanding, an ineliminable premiss of van Inwagen’s argument is demonstrably false and cannot be repaired. I will argue that this growing consensus is mistaken (...) and that a powerful argument relevantly similar to van Inwagen’s should still concern us, even when we understand ‘sufficient reason’ in terms of ground.

Principles of Philosophy. Author’s Letter to the Translator (Preface).

Principles of need are constantly referred to in health care priority setting. The common denominator for any principle of need is that it will ascribe some kind of special normative weight to people being worse off. However, this common ground does not answer the question how a plausible principle of need should relate to the aggregation of benefits across individuals. Principles of need are sometimes stated as being incompatible with aggregation and sometimes characterized as accepting aggregation in much (...) the same way as utilitarians do. In this paper we argue that if one wants to take principles of need seriously both of these positions have unreasonable implications. We then characterize and defend a principle of need consisting of sufficientarian elements as well as prioritarian which avoids these unreasonable implications. (shrink)

In set theory, a maximality principle is a principle that asserts some maximality property of the universe of sets or some part thereof. Set theorists have formulated a variety of maximality principles in order to settle statements left undecided by current standard set theory. In addition, philosophers of mathematics have explored maximality principles whilst attempting to prove categoricity theorems for set theory or providing criteria for selecting foundational theories. This article reviews recent work concerned with the formulation, investigation (...) and justification of maximality principles. (shrink)

I argue that moral principles involve the same sort of generalization as ordinary yet elusive generic generalizations in natural language such as ‘Tigers are striped’ or ‘Peppers are spicy’. A notable advantage of the generic view is that it simultaneously allows for pessimism and optimism about the role and status of moral principles in our lives. It provides a new perspective on the nature of moral principles on which principles are not apt for determining the moral (...) status of particular actions while they may be apt, and even fundamental, to our acquisition of moral knowledge. A natural consequence of the view is variation among moral principles, with some regularly warranting exceptions and some appearing arguably exceptionless. I will also argue that this generic conception of moral principles has significant advantages, as a normative model of moral reasoning, over the view of moral principles as defaults advanced in recent years.

Should our factual understanding of the world influence our normative theorising about it? G.A. Cohen has argued that our ultimate normative principles should not be constrained by facts. Many others have defended or are committed to various versions or subsets of that claim. In this paper I dispute those positions by arguing that, in order to resist the conclusion that ultimate normative principles rest on facts about possibility or conceivability, one has to embrace an unsatisfactory account of how (...) principles generate normative political judgments. So political theorists have to choose between principles ostensibly unbiased by our current understanding of human motivation and political reality, or principles capable of reliably generating political judgments. I conclude with wider methodological observations in defence of the latter option, and so of a return to political philosophy’s traditional blend of normative and descriptive elements. (shrink)

What are moral principles? In particular, what are moral principles of the sort that (if they exist) ground moral obligations or—at the very least—particular moral truths? I argue that we can fruitfully conceive of such principles as real, irreducibly dispositional properties of individual persons (agents and patients) that are responsible for and thereby explain the moral properties of (e.g.) agents and actions. Such moral dispositions (or moral powers) are apt to be the metaphysical grounds of moral obligations (...) and of particular truths about what is morally permissible, impermissible, etc. Moreover, they can do other things that moral principles are supposed to do: explain the phenomena “falling within their scope,” support counterfactuals, and ground moral necessities, “necessary connections” between obligating reasons and obligations. And they are apt to be the truthmakers for moral laws, or “lawlike” moral generalizations. (shrink)

This paper disputes the generalised definition of ‘aesthetic practice’ which leads deconstructive postmodern ‘aestheticians’ to equate aesthetic activities (eg., gardening, hair-braiding) with art-making. Reviving an understanding of Art’s single unifying Principle is a necessary precondition for restoring the meaning of an artistic practice. I describe its ancient origins, its disappearance in modernity, and reconstruct its defining criteria, showing why art cannot be confused with just any ‘cultural practice’ whereby one’s experience of the ‘general aesthetic’ can by merely mimicking Nature elicit (...) familiar empathic responses reflectively. I argue very little real art is being made today, and AI is perfectly suited to making what has replaced it: ‘cultural artefact’. In reconstructing this Principle, I show why artistic practice cannot be predicated merely upon theories of beauty/pleasure; but rather on what Aristotle deemed the ‘higher pleasure’ of making Reason (merging beauty with truth, and freedom with necessity). This overcomes Kant’s reflective aesthetic paradigm that engendered the misguided ‘experientialism’ dominating modern/postmodern “art” - undergirding an ‘artworld’ of mainly anti-Art (in what Bernard Stiegler calls the ‘catastrophe’ of modern aesthetic experience driven by the rise of ‘technicism’). A process for applying the Principle’s criteria is briefly outlined, demonstrating how to distinguish a ‘phenomenological experience’ from ‘ordinary experience’, and thus a genuinely poetic discourse from any other form of speculative discourse. Uncovering the Principle’s origins in Aristotle’s natural science (and his discernment of ‘making’ from ‘acting’ in technê), separating normative from theoretical aesthetics, and unveiling art’s ‘objective’ meaningfulness in any artwork’s phenomenology, reaffirms why art’s relation to the Person (its ‘anthropological phenomenology’) is of primary concern to aesthetes. I conclude with how the purpose of all inquiry into aesthetics is made more meaningful by reviving the Principle of Art, and why this essentially renders theoretical aesthetics redundant. (shrink)

This book provides a foundation to the principles of psychology. It draws upon the natural sciences, avoiding metaphysics, for the basis of its information. According to James, this book, assuming that thoughts and feelings exist and are vehicles of knowledge, thereupon contends that psychology, when it has ascertained the empirical correlation of the various sorts of thought or feeling with definite conditions of the brain, can go no farther as a natural science.

Many theorists have proposed that we can use the principle of indifference to defeat the inductive sceptic. But any such theorist must confront the objection that different ways of applying the principle of indifference lead to incompatible probability assignments. Huemer offers the explanatory priority proviso as a strategy for overcoming this objection. With this proposal, Huemer claims that we can defend induction in a way that is not question-begging against the sceptic. But in this article, I argue that the opposite (...) is true: if anything, Huemer’s use of the principle of indifference supports the rationality of inductive scepticism. (shrink)

This commentary explores the principle of proportionality as a possible solution to unresolved problems pertaining to the tensions among principles in various ethical frameworks for artificial intelligence (AI). Conceptual and procedural divergences in the sets of principles reveal uncertainty as to which ethical principles should be prioritized and how conflicts between them should be resolved. Moreover, there are externalities of employing the currently dominant AI methods, in particular for the environment. The principle of proportionality and a framework (...) of tests of necessity, desirability, and suitability can address some of the underlying issues and to ensure that other societal priorities are well taken into account. It is argued that at least in certain scenarios the perceived tensions can be false dichotomies. Proportionality presents a set of conditions to satisfy to justify the usage of certain AI methods, which can be further expanded to justifying using AI systems as such for a particular purpose.

The principle of least action (PLA) has often been cited as a counterexample to the dominant mode of causal explanation in physics. In particular, PLA seems to involve an appeal to final causes or some other teleological ideology. However, Ben-Menahem (Causation in science, Princeton University Press, Princeton, 2018) argues that such implications no longer apply given that PLA can be recovered as limiting case from quantum theory. In this paper, I argue that the metaphysical implications of PLA-based explanations are not (...) undermined by its status as derivative. However, I contend that PLA functions as a diachronic constraint that licenses explanations by constraint (Lange, Because without cause: non-casual explanations in science and mathematics. Oxford University Press, Oxford, 2016). PLA-based explanations, on this account, are non-causal but also differ from familiar cases of teleological explanations in several respects. (shrink)

I consider the question of how literally one can construe the “gauge argument,” which is the canonical means of understanding the putatively central import of local gauge symmetry principles for fundamental physics. As I argue, the gauge argument must be afforded a heuristic reading. Claims to the effect that the argument reflects a deep “logic of nature” must, for numerous reasons I discuss, be taken with a grain of salt.

In the development of governmental policy for artificial intelligence that is informed by ethics, one avenue currently pursued is that of drawing on “AI Ethics Principles”. However, these AI Ethics Principles often fail to be actioned in governmental policy. This paper proposes a novel framework for the development of ‘Actionable Principles for AI’. The approach acknowledges the relevance of AI Ethics Principles and homes in on methodological elements to increase their practical implementability in policy processes. As (...) a case study, elements are extracted from the development process of the Ethics Guidelines for Trustworthy AI of the European Commission’s “High Level Expert Group on AI”. Subsequently, these elements are expanded on and evaluated in light of their ability to contribute to a prototype framework for the development of 'Actionable Principles for AI'. The paper proposes the following three propositions for the formation of such a prototype framework: preliminary landscape assessments; multi-stakeholder participation and cross-sectoral feedback; and, mechanisms to support implementation and operationalizability.

An important goal of teaching ethics to engineering students is to enhance their ability to make well-reasoned ethical decisions in their engineering practice: a goal in line with the stated ethical codes of professional engineering organizations. While engineering educators have explored a wide range of methodologies for teaching ethics, a satisfying model for developing ethical reasoning skills has not been adopted broadly. In this paper we argue that a principlist-based approach to ethical reasoning is uniquely suited to engineering ethics education. (...) Reflexive Principlism is an approach to ethical decision-making that focuses on internalizing a reflective and iterative process of specification, balancing, and justification of four core ethical principles in the context of specific cases. In engineering, that approach provides structure to ethical reasoning while allowing the flexibility for adaptation to varying contexts through specification. Reflexive Principlism integrates well with the prevalent and familiar methodologies of reasoning within the engineering disciplines as well as with the goals of engineering ethics education.

The world is undeniably full of injustice. Many feel that much political philosophy is practically impotent and engaged instead in overly abstract theorising insufficiently sensitive to the realities of the world. One response to this concern is David Miller’s influential model of evidence-based political philosophy, which claims to be sensitive to empirical evidence from the social sciences, takes seriously people’s opinions, and defends the role of facts in grounding normative principles. Using various examples from the field of global justice, (...) one of Miller’s key areas of work, I show that Miller’s method is unconvincing on two levels. His theoretical argument for fact-dependence is flawed, and his practical argument for an opinion-sensitive political theory is either guilty of status quo bias or, in an attempt to escape it, becomes self-defeating. While the paper is primarily critical, I endeavour also to draw out the implications of my critiques for the role of the ‘real world’ in theorising. (shrink)

Leibniz was a philosopher of principles: the principles of Contradiction, of Sufficient Reason, of Identity of Indiscernibles, of Plenitude, of the Best, and of Continuity are among the most famous Leibnizian principles. In this article I shall focus on the first three principles; I shall discuss various formulations of the principles (sect. 1), what it means for these theses to have the status of principles or axioms in Leibniz’s philosophy (sect. 2), the fundamental character (...) of the Principles of Contradiction and Sufficient Reason (sect. 3), some attempts to demonstrate the Principles of Contradiction and Sufficient Reason (sect. 4), and one attempt to demonstrate the Principle of Identity of Indiscernibles (sect. 5).

The paper explores the relationship between the Principle of Double Effect and Just War Theory, with emphasis on their relationship in the philosophy of Thomas Aquinas. Both PDE and JWT are of Medieval origin, and are classical exponents of medieval moral philosophy. The main connection between them is, however, that they can both be viewed as theories about permissible violence and harm, that is theories about when it is morally permissible to harm and possibly kill another human being. The final (...) point of the paper is that PDE is an important element within JWT, or rather that when just war theorists manage to justify a certain types of violence they do so by extensive use of PDE. This only applies to one part of JWT, jus in bello, which concerns the actual morality of fighting, not the right to war itself. If these assumptions can be reasonably fleshed out, and if it is possible to show that PDE is of crucial importance to certain elements of jus in bello, such as methods for justifying civilian casualties, that would entail that our own moral examinations of warfare differ precisely because we either accept or don’t accept PDE as a viable and reasonable principle in normative ethics.

Anne Conway was an extraordinary figure in a remarkable age. Her mastery of the intricate doctrines of the Lurianic Kabbalah, her authorship of a treatise criticising the philosophy of Descartes, Hobbes, and Spinoza, and her scandalous conversion to the despised sect of Quakers indicate a strength of character and independence of mind wholly unexpected (and unwanted) in a woman at the time. Translated for the first time into modern English, her Principles of the Most Ancient and Modern Philosophy is (...) the most interesting and original philosophical work written by a woman in the seventeenth century. Her radical and unorthodox ideas are important not only because they anticipated the more tolerant, ecumenical, and optimistic philosophy of the Enlightenment, but also because of their influence on Leibniz. This fully annotated edition includes an introduction which places Conway in her historical and philosophical contexts, together with a chronology of her life and a bibliography. (shrink)

One of the most fundamental debates in metaethics is whether the normative facts are mind-dependent. Yet some philosophers are skeptical that mind-dependence is a category that's significant in the way metaethicists have assumed it is. In this paper, I consider a puzzle that showcases this skepticism, explaining how it undermines the most natural reading of the mind-dependence claim. I then go on to show that no modification of this reading within a certain class can hope to solve the problem. I (...) conclude by suggesting a new way that mind-dependence should be understood: mind-dependence is ultimately a matter of how normative principles are grounded. I develop this view briefly before concluding. (shrink)

The country's leading libertarian scholar sets forth the essential principles for a legal system that best balances individual liberty versus the common good.

The principle-based approach is a methodology to classify and analyse argumentation semantics. In this paper we classify seven of the main alternatives for argumentation semantics using a set of new robustness principles. These principles complement Baroni and Giacomin’s original classification and deal with the behaviour of a semantics when the argumentation framework changes due to the addition or removal of an attack between two arguments. We distinguish so-called persistence principles and monotonicity principles, where the former deal (...) with the question of whether a labelling or extension of an argumentation framework under a given semantics persists after a change, and the latter with the question of whether new labellings or extensions are created after a change. We furthermore show in which sense labelling-based and extension-based semantics lead to subtly different principles and results. Our results can be used for choosing a semantics for a particular application, or to guide the search for new argumentation semantics, but they have been used also in the design of algorithms.

Neuroethics applies cognitive neuroscience for prescribing alterations to conceptions of self and society, and for prescriptively judging the ethical applications of neurotechnologies. Plentiful normative premises are available to ground such prescriptivity, however prescriptive neuroethics may remain fragmented by social conventions, cultural ideologies, and ethical theories. Herein we offer that an objectively principled neuroethics for international relevance requires a new meta-ethics: understanding how morality works, and how humans manage and improve morality, as objectively based on the brain and social sciences. This (...) new meta-ethics will simultaneously equip neuroethics for evaluating and revising older cultural ideologies and ethical theories, and direct neuroethics towards scientifically valid views of encultured humans intelligently managing moralities. Bypassing absolutism, cultural essentialisms, and unrealistic ethical philosophies, neuroethics arrives at a small set of principles about proper human flourishing that are more culturally inclusive and cosmopolitan in spirit. This cosmopolitanism in turn suggests augmentations to traditional medical ethics in the form of four principled guidelines for international consideration: empowerment, non-obsolescence, self-creativity, and citizenship.

Concentrating upon applications that are most relevant to modern physics, this valuable book surveys variational principles and examines their relationship to dynamics and quantum theory. Stressing the history and theory of these mathematical concepts rather than the mechanics, the authors provide many insights into the development of quantum mechanics and present much hard-to-find material in a remarkably lucid, compact form. After summarizing the historical background from Pythagoras to Francis Bacon, Professors Yourgrau and Mandelstram cover Fermat's principle of least time, (...) the principle of least action of Maupertuis, development of this principle by Euler and Lagrange, and the equations of Lagrange and Hamilton. Equipped by this thorough preparation to treat variational principles in general, they proceed to derive Hamilton's principle, the Hamilton-Jacobi equation, and Hamilton's canonical equations. An investigation of electrodynamics in Hamiltonian form covers next, followed by a resume of variational principles in classical dynamics. The authors then launch into an analysis of their most significant topics: the relation between variational principles and wave mechanics, and the principles of Feynman and Schwinger in quantum mechanics. Two concluding chapters extend the discussion to hydrodynamics and natural philosophy. Professional physicists, mathematicians, and advanced students with a strong mathematical background will find this stimulating volume invaluable reading. Extremely popular in its hardcover edition, this volume will find even wider appreciation in its first fine inexpensive paperbound edition. (shrink)

Contextualist approaches to the Liar Paradox postulate the occurrence of a context shift in the course of the Liar reasoning. In particular, according to the contextualist proposal advanced by Charles Parsons and Michael Glanzberg, the Liar sentence L doesn’t express a true proposition in the initial context of reasoning c, but expresses a true one in a new, richer context c', where more propositions are available for expression. On the further assumption that Liar sentences involve propositional quantifiers whose domains may (...) vary with context, the Liar reasoning is blocked. But why should context shift? We argue that the paradox involves principles of contextualist reflection that explain, by analogy with well-known reflection principles for arithmetic, why context must shift from c to c' in the course of the Liar reasoning. This provides a diagnosis of the Liar Paradox—one that equally applies to two revenge arguments against contextualist approaches, one recently advanced by Andrew Bacon, the other mentioned by Charles Parsons and more recently revived by Cory Juhl.

Should particularists about ethics claim that moral principles are never true? Or should they rather claim that any finite set of principles will not be sufficient to capture ethics? This paper explores and defends the possibility of embracing the second of these claims whilst rejecting the first, a position termed 'principled particularism'. The main argument that particularists present for their position-the argument that holds that any moral conclusion can be superseded by further considerations-is quite compatible with principled particularism; (...) indeed, it is compatible with the idea that every true moral conclusion can be shown to follow deductively from a finite set of premises. Whilst it is true that these premises must contain implicit ceteris paribus clauses, this does not render the arguments trivial. On the contrary, they can do important work in justifying moral conclusions. Finally the approach is briefly applied to the related field of jurisprudence. (shrink)

I argue that, despite van Inwagen’s pessimism about the task, it is worth looking for answers to his General Composition Question. Such answers or ‘principles of composition’ tell us about the relationship between an object and its parts. I compare principles of composition with criteria of identity, arguing that, just as different sorts of thing satisfy different criteria of identity, they may satisfy different principles of composition. Variety in criteria of identity is not taken to reflect ontological (...) variety in the identity relation; I discuss whether variety in principles of composition should be taken to reflect ontological variety in the composition relation.

John Rawls based his theory of justice, in the work of that name, on a ‘Kantian interpretation’ of the status of human beings as ‘free and equal’ persons. In his subsequent, ‘political rather than metaphysical’ expositions of his theory, the conception of citizens of democracies as ‘free and equal’ persons retained its foundational role. But Rawls appealed only to Kant’s moral philosophy, never to Kant’s own political philosophy as expounded in his 1797 Doctrine of Right in theMetaphysics of Morals. I (...) argue here that the structure of Kant’s political philosophy, with its categories of the innate right to freedom, private acquired right and public right, can clarify the relationship between Rawls’s two principles of justice and his scheme of basic liberties and primary goods.

As embodied theories of cognition are increasingly formalized and tested, care must be taken to make informed assumptions regarding the nature of concepts and representations. In this study, we outline three reasons why one cannot, in effect, represent the same concept twice. First, online perception affects offline representation: Current representational content depends on how ongoing demands direct attention to modality-specific systems. Second, language is a fundamental facilitator of offline representation: Bootstrapping and shortcuts within the computationally cheaper linguistic system continuously modify (...) representational content. Third, time itself is a source of representational change: As the content of underlying concepts shifts with the accumulation of direct and vicarious experience, so too does the content of representations that draw upon these concepts. We discuss the ramifications of these principles for research into both human and synthetic cognitive systems. (shrink)

This paper compares and contrasts three different substantive principles of justice for making health care priority-setting or “rationing” decisions: need principles, maximising principles and egalitarian principles. The principles are compared by tracing out their implications for a hypothetical rationing decision involving four identified patients. This decision has been the subject of an empirical study of public opinion based on small-group discussions, which found that the public seem to support a pluralistic combination of all three kinds (...) of rationing principle. In conclusion, it is suggested that there is room for further work by philosophers and others on the development of a coherent and pluralistic theory of health care rationing which accords with public opinions.

Internationally, there is an on-going dialogue about how to professionalize ethics consultation services . Despite these efforts, one aspect of ECS-competence that has received scant attention is the liability of failing to adequately capture all of the relevant moral considerations in an ethics conflict. This failure carries a high price for the least powerful stakeholders in the dispute. When an ECS does not possess a sophisticated dexterity at translating what stakeholders say in a conflict into ethical concepts or principles, (...) it runs the risk of naming one side's claims as morally legitimate and decrying the other's as merely self-serving. The result of this failure is that one side in a dispute is granted significantly more moral weight and authority than the other. The remedy to this problem is that ECSs learn how to expand the diagnostic moral lens they employ in clinical ethics conflicts. (shrink)
