The success of movies like The Artist and Hugo recreated the wonder and magic of silent film for modern audiences, many of whom might never have experienced a movie without sound. But while the American silent movie was one of the most significant popular art forms of the modern age, it is also one that is largely lost to us, as more than eighty percent of silent films have disappeared, the victims of age, disaster, and neglect. We now know about (...) many of these cinematic masterpieces only from the collections of still portraits and production photographs that were originally created for publicity and reference. Capturing the beauty, horror, and moodiness of silent motion pictures, these images are remarkable pieces of art in their own right. In the first history of still camera work generated by the American silent motion picture industry, David S. Shields chronicles the evolution of silent film aesthetics, glamour, and publicity, and provides unparalleled insight into this influential body of popular imagery. Exploring the work of over sixty camera artists, Still recovers the stories of the photographers who descended on early Hollywood and the stars and starlets who sat for them between 1908 and 1928. Focusing on the most culturally influential types of photographs—the performer portrait and the scene still—Shields follows photographers such as Albert Witzel and W. F. Seely as they devised the poses that newspapers and magazines would bring to Americans, who mimicked the sultry stares and dangerous glances of silent stars. He uncovers scene shots of unprecedented splendor—visions that would ignite the popular imagination. And he details how still photographs changed the film industry, whose growing preoccupation with artistry in imagery caused directors and stars to hire celebrated stage photographers and transformed cameramen into bankable names. Reproducing over one hundred and fifty of these gorgeous black-and-white photographs, Still brings to life an entire long-lost visual culture that a century later still has the power to enchant.

This collection of original articles draws from a cross section of distinguished scholars of ancient Greek philosophy. It is focussed primarily on the philosophy of Aristotle but comprises as well studies of the philosophy of Socrates, Plato, and Epicurus. Its authors explore a range of complementary topics in value theory, moral psychology, metaphysics, natural philosophy, political theory, and methodology, highlighting the rich and lasting philosophical contributions of the thinkers investigated. Opening with an engaging intellectual autobiography of its honoree, Fred D. (...) Miller, Jr., the volume offers treatments of Socrates as a citizen; Plato’s attitude towards poetry; Socratic self-knowledge; Plato’s conception of law in his Republic; explorations of reason, goodness, and moral conduct in Plato; Platonic metaphysics; Aristotelian causation; Aristotelian metaphysics and normativity; natural philosophy in Aristotle; Aristotelian logic; political theory and approaches to justice in Aristotle’s Politics; methodological reflections on how best to approach Aristotle’s indefensible ideas; and closes with a reconsideration of Epicurus on death and the art of dying. Altogether, the volume reflects the richness of the ongoing community of philosophical scholars dedicated to reconstructing, assessing, and criticizing the principal philosophers of the ancient world, whose epoch-forming explorations of the key elements of human life—considered socially, politically, psychologically, and metaphysically—remain topics of lively investigation today. It will be of interest to philosophers of many stripes, including those with a primary interest in ancient philosophy but extending as well to those with systematic interests in the themes it explores. This volume will be a valuable addition to all libraries serving communities dedicated to researching and studying the origins of Western philosophy. (shrink)

In anticipation of extraterritorial application of antiabortion laws, many states have enacted laws that attempt to shield abortion providers, helpers, and patients from civil, professional, or criminal liability associated with legal abortion care. This essay analyzes and compares the statutory schemes of the seven early adopting shield states: California, Connecticut, Delaware, Illinois, Massachusetts, New Jersey, and New York. After describing what the laws do and how they operate, we offer reflections on coming disputes, areas of legal uncertainty, and ways to (...) improve future shield laws. (shrink)

One way to determine whether a mental condition should be considered a disorder is to first give necessary and sufficient conditions for something to be a disorder and then see if it meets these conditions. But this approach has been criticized for begging normative questions. Concerning autism (and other conditions), a neurodiversity movement has arisen with essentially two aims: (1) advocate for the rights and interests of individuals with autism, and (2) de-pathologize autism. We argue that denying autism’s disorder status (...) could undermine autism’s exculpatory role in cases where individuals with autism are charged with a crime. Our argument raises a dilemma for the neurodiversity movement: advocating for the rights and interests of individuals with autism may require viewing autism as a condition that can be inherently disabling (at least for some individuals). If this is right, autism’s disorder status might be maintained (again, at least for some individuals) without deriving this result from any general account of disorder. (shrink)

ABSTRACT:Analytic philosophers have criticized A. N. Whitehead's metaphysics for being obscure, yet several such philosophers have espoused positions in metaphysics and philosophy of mind that were advanced by Whitehead in the 1920s. In this paper, we evaluate the merits and demerits of these criticisms by Bertrand Russell, W. V. Quine, Karl Popper, and others and then demonstrate the affinities and contrasts in the positions advanced by Galen Strawson, David Chalmers, Thomas Nagel, and Whitehead regarding so-called ‘analytic panexperientialism’.

My purpose in this essay is to provide a critical survey of arguments within recent analytic philosophy regarding the so-called “mind-body problem” with a particular view toward the relationship between these arguments and the philosophy of A.N. Whitehead (and Charles Hartshorne’s closely related views).1In course, I shall argue that Whitehead’s panexperientialist physicalism avoids paradoxes and difficulties of both materialist-physicalism and Cartesian dualismas advocated by a variety of analytic philosophers. However, and I believe that this point is not often sufficiently recognized, (...) analytic philosophy of mind is no monolith, and there are those who have found some form of panexperientialism to be attractive enough to merit serious consideration or even full-fledgedacceptance (David Chalmers, Thomas Nagel, Ralph Pred, William Seager, and Galen Strawson among them). A critical discussion of such thinkers should beincluded in any adequate survey of the relation between process panexperientialism and the analytic tradition. Moreover, the revisionary strain of the analyticaltradition which looks to natural science for its construction of worldviews (Broad, Russell, Bunge, Carnap, Quine, etc.) would move us in the direction of examining arguments concerning Whitehead’s view and contemporary empirical scientific considerations. (For a discussion of the basic nature of analytic philosophy and the descriptive and revisionary approaches contained within it, see my Process and Analysis, 5-9, 12-13, 57; and McHenry.) Here I shall argue that Whiteheadian panexperientialism very naturally accommodates important aspects of quantum theory, including the top-down causation involved in neuroplastic phenomena under a quantum mechanical interpretation of brain processes and in so-called Quantum Zeno Effect. The overall picture which emerges is that Whitehead’s position is (at the very least) a strongly plausible alternative in philosophy of mind.While I must confess that this essay can only represent the merest sketch—indeed an adequate treatment of the richly complex interpretive, comparative, and substantive philosophical issues here requires at the very least a monograph—I nonetheless hope to present a coherent and useful précis of major arguments and comparative conceptual relationships, especially for the reader who may not be readily familiar with this terrain. I thus hope that this essay will serve as a short expository and critical introduction to the interface between process and analytic philosophy of mind, and a presentation of the several theoretical advantages gained by listening to Whitehead’s theory as it connects with concerns of analytic philosophers.I shall proceed by first working though the main outlines of John Searle’s important and widely reaching “The Recent History of Materialism,” an essay which exposes critical flaws in a variety of materialist theories in ways which Whiteheadians should find especially fitting and congenial. I shall then examine defenses of dualism and the relation of Whitehead to such defenses, followed by a separate section on Chalmers, Nagel, and Pred. I will then consider a number ofimportant objections to process panexperientialism, including objections arising from the work of Jaegwon Kim and John Searle. I close with a discussion of thementioned empirical scientific arguments. (shrink)

One of the standard objections against the impossibility of infinite regress is associated with David Hume and Paul Edwards, but originates with William Ockham. They claim that in an infinite regress every member of the series is explained, and nothing is unexplained. Every member is explained by the one before it, and the series as a whole is nothing over and above its members, and so needs no cause of its own. Utilizing the well-known Thomistic distinction between essentially ordered (...) and accidentally ordered causal series, I show that the Hume-Edwards-Ockham objection fails to touch Aquinas’s argument against the impossibility of infinite regress in an essentially ordered series. However, Aquinas also argues that accidentally ordered causal series can only regress infinitely if supported by an everlasting essential cause. The Hume-Edwards-Ockham objection does raise a question about this thesis, but I show how St. Thomas can reply to it convincingly. (shrink)

Is it possible for a liberal society to have an established church? After outlining the conditions for liberal establishment, I take from David Hume a secular argument in its favour that points to the moderating effect of establishment on religious discourse and practice. I examine the claim that state support for religion violates liberal equality, and argue that, with respect to state-provided public goods generally, what matters is that the whole package should be of roughly equal benefit to each (...) citizen; it is not required that every citizen should value each distinct good. I claim that religious establishment can have valuable effects for both believers and non-believers, and thereby count as a public good. I then examine the charge that establishment always conveys a message of disparagement to those outside the favoured church, making them into second-class citizens, as both Martha Nussbaum and Cécile Laborde have claimed. Understood as a claim about the experience of minority groups, however, it is unsupported by empirical evidence. Understood as an interpretative claim about the meaning of establishment, it fails to distinguish between privileging an institution and privileging the people attached to it. Finally, I point out that religious minorities may favour an established church as a shield against the pervasive secularism of most modern liberal societies. (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)

Early in this volume, David Ehrenfeld describes what prophecy really is. Referring to the biblical prophets, he says they were not the "holy fortunetellers that the word prophet has come to signify....The business of prophecy is not simply foretelling the future; rather it is describing the present with exceptional truthfulness and accuracy." Once this is done, then it can be seen that broad aspects of the future have suddenly become apparent. The twentieth century is drawing to a chaotic close (...) amidst portents of unprecedented change and upheaval. The unravelling of societies and civilizations and the destruction of nature march together--linked--a fact whose enormous significance is often lost. In Beginning Again, David Ehrenfeld has undertaken the difficult task of describing the present clearly enough to reveal the future. Out of his broad vision emerges a glimpse of a new millennium: a vision at once frightening and comforting, a scene of great devastation and great rebuilding. Ehrenfeld ranges far and wide to present a coherent vision of our relationship with Nature--its many aspects and implications--as our century opens into the next millennium. Whether he is writing about the problem of loyalty to organizations, rights versus obligations, our over-managed society, the vanishing of established knowledge, the failure of experts, the triumph of dandelions, Dr. Seuss, Edward Teller, or the future of farming, he is always concerned with the intricate interaction between technology and nature. As in his classic book, The Arrogance of Humanism, Ehrenfeld never loses sight of our fatal love affair with the fantasy of control. We now have no choice, he argues, but to transform the dream of control, of progress, from one of overweening hubris, love of consumption, and the idiot's goal of perpetual growth, to one based on "the inventive imitation of nature," with its honesty, beauty, resilience, and durability. Few American writers and even fewer scientists can describe these timeless, transcendent qualities of nature so well. In "Places," the opening chapter, David Ehrenfeld tells about nightly vigils he spent alone on the moonlit beach of Tortuguero, watching giant sea turtles emerging from the sea to lay their eggs in the black sand where they were born. "I could watch the perfect white spheres falling," he writes. "Falling as they have fallen for a hundred million years, with the same slow cadence, always shielded from the rain or stars by the same massive bulk with the beaked head and the same large, myopic eyes rimmed with crusts of sand washed out by tears. Minutes and hours, days and months dissolve into eons. I am on an Oligocene beach, an Eocene beach, a Cretaceous beach--the scene is the same. It is night, the turtles are coming back, always back; I hear a deep hiss of breath and catch a glint of wet shell as the continents slide and crash, the oceans form and grow.". (shrink)

This article analyzes testimony before four Congressional subcommittees, between 1972 and 1975, on a proposed federal shield law. it is argued that within the testimony the press articulates a public, professional mission, but it fails to clearly define who qualifies for protection as a journalist.

Beginning with the idea of mathematical proof and the need for it, associated technical and logical skills are developed with care and then brought to bear on the core material of analysis in such a lucid presentation that the development reads naturally and in a straightforward progression. Retaining the core text, the second edition has additional worked examples which users have (...) indicated a need for, in addition to more emphasis on how analysis can be used to tell the accuracy of the approximations to the quantities of interest which arise in analytical limits.

With reference to the virtue-ethics tradition, especially the system of St. Thomas Aquinas, this essay interprets the pentangle emblazoned on Gawain’s shield as symbolizing the perfection of interconnected virtues, and the Green Knight as figuring Christ in his martyrdom. Linking these two strands of meaning is the Thomist idea of fortitude, the virtue under particular scrutiny in the poem. Gawain fulfills the secondary part of fortitude, attack, while the Green Knight fulfills the primary part, endurance, and is identified with Christ. (...) His axe, holly bob, and green coloration, and even his menacing aspect, all foster this significance. (shrink)

Many scholars have argued that the Protestant Reformation generally departed from virtue ethics, and this claim is often accepted by Protestant ethicists. This essay argues against such discontinuity by demonstrating John Calvin’s reception of ethical concepts from Augustine and Aristotle. Calvin drew on Augustine’s concept of eudaimonia and many aspects of Aristotle’s Nicomachean Ethics , including concepts of choice, habit, virtue as a mean, and the specific virtues of justice and prudence. Calvin also evaluated the problem of pagan virtue in (...) light of traditional Augustinian texts discussed in the medieval period. He interpreted the Decalogue as teaching virtue, including the cardinal virtues of justice and temperance. Calvin was not the harbinger of an entirely new ethical paradigm, but rather a participant in the mainstream of Christian thinkers who maintained a dual interest in Aristotelian and Augustinian eudaimonist virtue ethics.

ExcerptHuman rights organizations for the past few decades have generally attempted to promote international law against the principle of state sovereignty in order to establish human rights norms worldwide. This approach presumes the universality of human rights is in fundamental opposition to the principle of sovereignty because this principle can be used by governments to shield themselves from outside criticism. By contrast, the U.S. State Department’s Report of the Commission on Unalienable Rights has outlined an approach that emphasizes not just (...) the compatibility between universal human rights and state sovereignty but even their dependence on each other.1 We see the results of this clash in the response to the Report by Kenneth Roth, executive director of Human Rights Watch and one of the expert witnesses during the commission’s proceedings.2 He sees in the Report’s foregrounding of the Universal Declaration of Human Rights “a frontal assault on international human rights law” because it shifts attention away from international law and toward more informal documents such as the Universal Declaration, which lays out a set of goals rather than legally binding commitments.

This Article discusses a triangle of forces that affect the activity of small-medium enterprises. These forces are: limited liability, shareholder guarantees, and bankruptcy. Limited liability encourages entrepreneurship by reducing the personal risks shareholders are exposed to as a result of business failure. However, the limited liability shield creates the potential moral hazard of overinvestment. That is, the entrepreneur may involve the corporation in overly risky projects. To combat this risk, the lending practice requires entrepreneurs to sign a personal guarantee for (...) corporate debt. The guarantee serves as a bonding device that forces the entrepreneur to internalize the costs of the corporate activity. This Article first argues that while personal guarantees can serve this economic goal, the lending industry demands them excessively and they are overused. The overuse of guarantees unnecessarily subjects good corporate borrowers as well as bad ones to this practice and causes underinvestment. The third force of the triangle, a discharge of the shareholder’s debts in bankruptcy, may balance this inefficiency. It potentially softens the effect of the guarantee and thus requires the lender to further gather borrowerspecific information at the lending stage. Unfortunately, personal bankruptcy is underused by individual debtors mainly because of the stigma it implies. To rebalance the triangle, this Article proposes to encourage the shareholder’s partial relief of the guarantee through an amicable procedure. I call this procedure Velvet Bankruptcy. Velvet Bankruptcy would first procedurally consolidate the private collection from the shareholder-guarantor with the pending corporate bankruptcy case, by authorizing the court to extend the automatic stay to protect the shareholder-guarantor. To the extent the court is convinced that the collection would render the shareholder insolvent, it could reduce the guarantor’s liability. This would effectively constitute discharge without officially declaring the shareholder bankrupt. (shrink)

What is the cultural value of illegal works that violate the copyrights of popular fiction? Why do they persist despite clear and stringent intellectual property laws? Drawing on the disciplines of new media, law, and literary studies, Illegal Literature suggests that extralegal works such as fan fiction are critical to a system that spurs the evolution of culture. Reconsidering voices relegated to the cultural periphery, David S. Roh shows how infrastructure--in the form of legal policy and network distribution--slows or (...) accelerates the rate of change. He analyzes the relationship between intellectual property rights and American literature in two recent copyright disputes. And, in comparing American fan fiction and Japanese dojinshi, he illustrates how infrastructure and legal climates detract from or encourage fledgling creativity. Illegal Literature fills a crucial gap between the scholarly and the popular by closely examining several modes of marginalized cultural production. Roh makes the case for protecting an environment conducive to literary heresy, the articulation of an accretive rather than solitary authorial genius, and the idea that letting go rather than holding on is important to a generative creative process. In a media ecology inundated by unauthorized materials, Illegal Literature argues that the proliferation of unsanctioned texts may actually benefit literary and cultural development. (shrink)

This is a series of essays critical of the utilitarian bioethics now dominating contemporary discussion.

‘Hoplites are troops who take their name from their shields’. ‘The individual infantryman took his name, hoplites, from the hoplon or shield’. Such is the orthodox view. This paper will endeavour to show that its basis is inadequate. Rather, we shall argue, hoplites took their name from their arms and armour as a whole, their hopla in that all-encompassing sense; so that the original and essential meaning of the word hoplite was nothing more than ‘armed man’.

Adorning the cover of Mourning Becomes the Law is a replica of Gathering the Ashes of Phocion, a painting by Nicholas Poussin. An Athenian beyond reproach, Phocion had been put to death by tyrants who had taken control of the city, his ashes left on the pyre. In the darkened foreground, Phocion’s wife gathers her husband’s ashes on her hands and knees while her female attendant shields her from the view of the city, which rises up behind them. With (...) its glittering architecture and recreating citizens, the city seems impervious to this scene of mourning. Yet, Rose warns, there is not an unmediated opposition of individual love and worldly injustice here; rather, this act by Phocion’s wife is a finite act of justice that will have its bearing on the political life of the city. Mourning, “which draws on transcendent but representable justice”, becomes the law. Mourning Becomes the Law is the philosophical counterpart to Love’s Work, a memoir in which Rose reflects on the deaths of loved ones and, ultimately, her own impending death from cancer. Yet, while death haunts Love’s Work, she does not succumb to melancholia, but, rather, reaffirms her commitment to “staying in the fray.” In Mourning Becomes the Law, her final work, Rose again grapples with the meaning of death, but this time only as part of a broader theme that has preoccupied her for many years, namely, the nihilistic implications of postmodernism. Rose seeks to reveal the incoherence of postmodernism’s search for a “new ethics” that is divorced from the metaphysical inquiries of the tradition. By tearing ethics from metaphysics to give “the other” its absolute due, she argues, postmodernism has deprived itself of the resources necessary for an ethical project, and has thus “condemned itself to impotence and failure.” These resources, which are only to be found “in the politics which has been disowned, and in the theology which has been more thoroughly suppressed,” are drawn upon by Rose herself, who would “renew and reinvent” classical reflection “on the analogies between the soul, the city and the sacred”.

_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?

We examine two different descriptions of the behavioral functions of the hippocampal system. One emphasizes spatially organized behaviors, especially those using cognitive maps. The other emphasizes memory, particularly working memory, a short-term memory that requires iexible stimulus-response associations and is highly susceptible to interference. The predictive value of the spatial and memory descriptions were evaluated by testing rats with damage to the hippocampal system in a series of experiments, independently manipulating the spatial and memory characteristics of a behavioral task. No (...) dissociations were found when the spatial characteristics of the stimuli to be remembered were changed; lesions produced a similar deficit in both spatial and nonspatial test procedures, indicating that the hippocampus was similarly involved regardless of the spatial nature of the task. In contrast, a marked dissociation was found when the memory requirements were altered. Rats with lesions were able to perform accurately in tasks that could be solved exclusively on the basis of reference memory. They performed at chance levels and showed no signs of recovery even with extensive postoperative training in tasks that required working memory. In one experiment all the characteristics of the reference memory and working memory procedures were identical except the type of memory required. Consequently, the behavioral dissociation cannot be explained by differences in attention, motivation, response inhibition, or the type of stimuli to be remembered. As a result of these experiments we propose that the hippocampus is selectively involved in behaviors that require working memory, irrespective of the type of material that is to be processed by that memory.

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)

DCPS is a connectionist production system interpreter that uses distributed representations. As a connectionist model it consists of many simple, richly interconnected neuron‐like computing units that cooperate to solve problems in parallel. One motivation for constructing DCPS was to demonstrate that connectionist models are capable of representing and using explicit rules. A second motivation was to show how “coarse coding” or “distributed representations” can be used to construct a working memory that requires far fewer units than the number of different (...) facts that can potentially be stored. The simulation we present is intended as a detailed demonstration of the feasibility of certain ideas and should not be viewed as a full implementation of production systems. Our current model only has a few of the many interesting emergent properties that we eventually hope to demonstrate: It is damage‐resistant, it performs matching and variable binding by massively parallel constraint satisfaction, and the capacity of its working memory is dependent on the similarity of the items being stored.

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)

Unsupervised learning algorithms are widely used for many important statistical tasks with numerous applications in science and industry. Yet despite their prevalence, they have attracted remarkably little philosophical scrutiny to date. This stands in stark contrast to supervised and reinforcement learning algorithms, which have been widely studied and critically evaluated, often with an emphasis on ethical concerns. In this article, I analyze three canonical unsupervised learning problems: clustering, abstraction, and generative modeling. I argue that these methods raise unique epistemological and (...) ontological questions, providing data-driven tools for discovering natural kinds and distinguishing essence from contingency. This analysis goes some way toward filling the lacuna in contemporary philosophical discourse on unsupervised learning, as well as bringing conceptual unity to a heterogeneous field more often described by what it isnot(i.e., supervised or reinforcement learning) than by what itis. I submit that unsupervised learning is not just a legitimate subject of philosophical inquiry but perhaps the most fundamental branch of all AI. However, an uncritical overreliance on unsupervised methods poses major epistemic and ethical risks. I conclude by advocating for a pragmatic, error-statistical approach that embraces the opportunities and mitigates the challenges posed by this powerful class of algorithms. (shrink)

Necessity and sufficiency are the building blocks of all successful explanations. Yet despite their importance, these notions have been conceptually underdeveloped and inconsistently applied in explainable artificial intelligence, a fast-growing research area that is so far lacking in firm theoretical foundations. In this article, an expanded version of a paper originally presented at the 37th Conference on Uncertainty in Artificial Intelligence, we attempt to fill this gap. Building on work in logic, probability, and causality, we establish the central role of (...) necessity and sufficiency in XAI, unifying seemingly disparate methods in a single formal framework. We propose a novel formulation of these concepts, and demonstrate its advantages over leading alternatives. We present a sound and complete algorithm for computing explanatory factors with respect to a given context and set of agentive preferences, allowing users to identify necessary and sufficient conditions for desired outcomes at minimal cost. Experiments on real and simulated data confirm our method’s competitive performance against state of the art XAI tools on a diverse array of tasks. (shrink)

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.

To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal identity. First I argue that overemphasis (...) of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay. I would also like to thank Ellen Paul, whose suggestions have helped greatly to improve the essay's style and content. (shrink)

This paper describes differences in two perspectives on the idea of virtue as a theoretical foundation for positive organizational ethics (POE). The virtue ethics perspective is grounded in the philosophical tradition, has classical roots, and focuses attention on virtue as a property of character. The positive social science perspective is a recent movement (e.g., positive psychology and positive organizational scholarship) that has implications for POE. The positive social science movement operationalizes virtue through an empirical lens that emphasizes virtuous behaviors. From (...) a virtue ethics perspective, a behaviorally based account of virtue is a weak theory of virtue. Observations are suggested for integrating the two perspectives. First, virtue should always be understood as an excellence and is often an optimal point between extreme dysfunctions on continuum of potential states. Second, an empirical exploration of virtue needs to account for character and context. Finally, the properties of organization-level virtue need to be further specified and explored. Implications and directions for future research are discussed. (shrink)

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)
