A framework for representing a specific kind of emergent property instance is given. A solution to a generalized version of the exclusion argument is then provided and it is shown that upwards and downwards causation is unproblematical for that kind of emergence. One real example of this kind of emergence is briefly described and the suggestion made that emergence may be more common than current opinions allow.

In lieu of an abstract, here is a brief excerpt of the content:Ovid, Art, and Eros PAUL BAROLSKY OVIDIO, AMORI, miti e altre storie or Ovid: Loves, Myths, and Other Stories is the copiously illustrated catalogue to the monumental exhibition mounted in 2008–2009 at the Scuderie del Quirinale, in Rome, in celebration of the great Roman poet and his world. This handsome tome is many books in one: a beautiful album of color plates illustrating a wide range of fascinating (...) objects, an overview of Ovid’s life, works and influences—a book for amateurs and specialists alike, a book to delight and instruct. The book includes paintings and sculpture but also pottery, coins, and jewelry. There is something for everybody here. Ovidio is divided into relatively brief sections written by numerous scholars who treat such topics as Ovid and myth, Ovid the love poet, Ovid in exile, Ovid and Augustan Rome, Ovid and the figurative arts, and Ovid in the seventeenth century. The book’s attention to illustrated editions of Metamorphoses, and especially the Ovide moralisé, is notable and refreshing. I think it fair to say that the exhibition and its catalogue are, not surprisingly, dominated by Metamorphoses and the ways in which artists illustrated its stories over the centuries. The myths of Venus and Adonis, Narcissus and Echo, Icarus and Daedalus, and Jupiter and Europa are among the numerous Ovidian stories that get extensive treatment here. We need to recall that no ancient author in the Hellenic tradition is so copiously illustrated as is Ovid—a fact that is Ovidio, amori, miti e altre storie, ed Francesca Ghedini et al. Rome 2018, 310 pages; isbn 9788856906486; €33.15. arion 27.2 fall 2019 easily taken for granted. A consummate story teller, Ovid inspired the pictorial tales of Poussin, Rubens, Rembrandt, and Velázquez, among other masters. Often in this book, works of mythological art are seen in the context of Ovid, even when there is no specific association between image and text. Such is the case when, for example, we encounter the well-known Praxitelean Aphrodite pudica in the Uffizi which inspired Botticelli’s similar Aphrodite now in the Musei Reali of Turin. There is nothing that links the statue and the painting to Ovid other than the fact that their makers, like the poet, write about the goddess of love. Ever so many mythological works suggest the arousal of desire. The Praxitelean Aphrodite modestly covers her body with both of her hands. Understandably, since according to an ancient tale, a young man was so aroused by the statue that he left a stain upon her. In short, we are in the realm of erotic art. The Hellenistic statue of Leda and the Swan in the archeology museum of Venice is an excellent example of erotic art featured in this book, even though Leda is mentioned only in passing in Metamorphoses. She seems to swoon in rapture as the bird (Jupiter in avian guise) slithers between her legs, beak seeking lips. Scarcely resisting, Leda reaches ambiguously downward as if in search of something, and we can well imagine what that might be. That her lower hand is invisible contributes to its suggestiveness. Leda’s upper hand is pressed against the swan’s sinuous neck, by no means a gesture of resist170 ovid, art, and eros Figure 1: Leda and the Swan. Venice, Museo Archeologico Nazionale, 2018. Eric Vandeville / akg-images. ance, I believe, even though in the myth she is taken by force. What we see is what the Ovid catalogue calls a “voluptuous amplexus.” The story of Leda and the Swan is forever told by painters in various erotic ways. When, later in the Renaissance, Correggio pictures the momentous event he shows the swan mounting Leda who, in this case, receives the bird in a seated position. As the bird engages the nymph, feathers pressed against her inner thigh, the swan, as in the ancient statue, seeks out her mouth with his beak—a juxtaposition as phallic as it is oral. The Leonardesque smile of Leda betokens not fear or violence but pleasure—a decidedly carnal pleasure. In a different context, Vasari wrote that Correggio painted not colors but flesh. When Leonardo himself pictured Leda, he delicately rendered the... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reflections on Raphael PAUL BAROLSKY The essence of all appreciation and analysis of art is the translation of visual perceptions into compelling verbal form. —Ralph Lieberman cultural unity Horace Walpole, Sir Joshua Reynolds, Johann Wolfgang Goethe, Eugène Delacroix, Honoré Balzac, Friedrich Hegel, Charles Baudelaire, Friedrich Nietzsche, Pierre Renoir, Nathaniel Hawthorne, August Wilhelm von Schlegel, Heinrich von Kleist, Franz Grillparzer, Fyodor Dostoyevsky, Ivan Turgenev, Wilhelm Heinrich Wackenroder, George Eliot, (...) Jean-Auguste Dominique Ingres, Roger Fry, Bernard Berenson, Theodor Hetzer, Roberto Longhi, Heinrich Wölfflin, and Stendhal are among the many essayists, critics, novelists, poets, painters and art historians who have responded to Raphael’s work as painter, architect or archeologist over the centuries. I can well imagine all of those listed above, among many others, united in an imaginary painting similar to the School of Athens—in other words, a vision that reconciles their various views of the world in a harmony analogous to the unity of philosophers in Raphael’s great fresco. Raphael is a towering figure in the history of European culture. The year 2020 was the 500th anniversary of the death of the great painter in Rome at the age of thirty-seven. In the wake of recent exhibitions that commemorated the artist’s achievement, I propose to touch briefly and lightly on a few aspects arion 28.2 fall 2020 100 reflections on raphael of Raphael’s life and works. Please think of these remarks as a series of suggestions, not attempts at definitive interpretation. I think of this essay as a rather experimental piece. THE SCHOOL OF ATHENS i should like to begin with a few brief remarks on what must be Raphael’s most famous work of art. I mean his School of Athens (fig. 1), which is, like Leonardo’s Mona Lisa and Last Supper or like Michelangelo’s David and Creation of Adam, an image widely known and admired. What more is there to say about The School Of Athens, one of the central images in the Stanza della Segnatura? You might spend the rest of your life reading about this great work and never understand it fully. Nevertheless, I want to focus for a moment on a central detail of the work and, on the basis of my description, point to a significant aspect of the fresco that has been universally overlooked. First the description, then the aperçu. Fig. 1. School of Athens. Ca. 1510–1512. Photo Credit : Erich Lessing / Art Resource, NY. Paul Barolsky 101 At the center of the School of Athens we behold the two great philosophers of classical antiquity: Plato and Aristotle. Plato holds a copy of his Timaeus, a dialogue that concerns the harmony of the heavens; Aristotle holds a copy of his Ethics, a work that pertains to human relations in this world. It was the goal of Renaissance thinkers to create a harmony or concord of the thought of these philosophers: a Concordia Platonis et Aristotelis. Raphael’s fresco, as is well known, presents the visual ideal of such harmony. Whereas Aristotle gestures downward, alluding to this world, in which his Ethics matter, Plato points heavenward, evoking the order of the cosmic realm described in Timaeus. Raphael makes visible the ideal of concordia when he movingly pictures the way in which the two philosophers gaze into each other’s eyes, as if to suggest this harmony. Borrowing from the language of Raphael ’s friend, Baldassare Castiglione, Raphael renders “the joining” of their souls. The monumental architecture of the scene, which echoes Bramante and has taproots in Piero della Francesca and Perugino, consists of three barrel-vaults beyond which we see patches of blue sky and puffs of cloud (fig. 2). The grandiose architecture of the image magnifies Raphael’s philosophers. Within this architectural framework, Plato’s gesture is deeply meaningful, since it prompts the viewer to look up and thus ascend toward the perfection of the celestial realm, beyond the imperfections of the physical world. Above the first barrel vault in the fresco we behold a section of the drum of a dome which is open to the sky. Within this section of drum there are two columns that are lined up directly...

Seeing Nature is a series of true stories or parables that offer tools for understanding relationships in the natural world. Many of the stories take the reader to wild landscapes, including canyons, tundra, and mountain ridges, while others contemplate the human-made world: water-diversion trenches and supermarket check-out lines. At one point, Krafel discovers a world in a one-inch-square patch of ordinary ground. Inspiring for parents and teachers seeking to encourage excitement about the positive role of people in nature, Krafel's work (...) harkens to St. Exupery's The Little Prince, Annie Dillard's Pilgrim at Tinker Creek, and Jean Giono's The Man Who Planted Trees. As Barbara Damrosch has noted: [This book] is a gift.... With curiosity, wit, and a spare and graceful style, Krafel notes why birds in flocks land as they do, how islands can move upstream in a river, how kelp forests, swaying gently, break the force of the sea's power, how tundra plants create whole ecosystems on bare rock from mere specks of life. Yet there are no long-winded sermons about the woods, or cute anthropomorphizations of animals. The book's economical, unsentimental style is part of its originality. Paul Krafel's years as a park ranger afforded him time to walk and think--his job was to observe the world around him. He is now a teacher, creating a curriculum for young people that is built on a startlingly simple truth: The world around us is an extended conversation between "upward spirals"--nature in regenerative, procreative modes--and downward spirals toward entropy and disintegration. As nature refreshes and rebuilds, the downward spirals are overcome. Nature's process becomes the process of replenishing hope. (shrink)

Holism and emergence are coherent notions. The paper points to the classes of emergent phenomena -- such as autocatalysis -- that are taken as commonplace phenomena in biological sciences. Thus it questions the Democritean credo, “wholes are completely determined by their parts” (in some of its forms, called mereological determinism), that has become a dogma of contemporary philosophy. A living thing requires the ability to initiate, mediate and terminate processes that produce products that make up the whole. Autocatalysis is one (...) such mechanism, and its action at the level of the whole produces effects on the parts such that the properties, manifested by the parts in the absence of the whole engaged in autocatalysis, are altered. For these reasons, some writers suggest that autocatalysis is a law of organization and that it is emergent. It also appears that this is a case of downward causation -- one that clearly occurs in nature. If this is not a case of downward causation on Kim’s terms, then biological systems that are claimed to be emergent do not need to involve downward causation in his sense. The author thinks that this constitutes downward causation in an important sense -- the causal properties of the whole drive the behavior of the parts. Another set of examples comes from chaos dynamics. Relying on this evidence, the author challenges the Democritean credo (and mereological determinism) and shifts the onus of proof. (shrink)

This book is an inquiry into the motivation for altruistic behavior. It uncovers the condition that prompts or sometimes even compels us to act intentionally for the benefit of others. This condition, the pre-reflective experience of another person as a self-conscious individual just like oneself, finds its origin in the very structure of the mind. The essay is a synthesis of evidence from neuroscience, phenomenology, Eastern philosophy, analytic philosophy of mind, and cognitive psychology. Hence, it is an excellent example of (...) work in applied cognitive science. The book includes a critique of the several main approaches to the explanation of the motivation for altruistic behavior: biological, psychological, and philosophical. The path of the main inquiry produces several innovative proposals in the philosophy of mind in addition to the main conclusion. Included in these are a detailed account of the structure of the human mind, an ontological categorization of mental states, a naturalistic explanation of so-called mystical states, a proposal for the role of consciousness in the downward causation of physical events, a new interpretation of the Buddhist doctrine of no-self and a unique view of the nature of love.

BackgroundCoaching is increasingly viewed as a dyadic exchange of verbal and non-verbal interactions driving clients' progress. Yet, little is known about how the trajectory of dyadic interactions plays out in workplace coaching.MethodThis paper provides a multiple-step exploratory investigation of movement synchrony of dyads in workplace coaching. We analyzed a publicly available dataset of 173 video-taped dyads. Specifically, we averaged MS per session/dyad to explore the temporal patterns of MS across the cluster of dyads that completed 10 sessions, and a set (...) of 173 dyadic interactions with a varied number of sessions. Additionally, we linked that pattern to several demographic predictors. The results indicate a differential downward trend of MS.ResultsDemographic factors do not predict best fitting MS curve types, and only client age and coach experience show a small but significant correlation.DiscussionWe provide contextualized interpretations of these findings and propose conceptual considerations and recommendations for future coaching process research and practice.

When attempting to predict future events, people commonly rely on historical data. One psychological characteristic of judgmental forecasting of time series, established by research, is that when people make forecasts from series, they tend to underestimate future values for upward trends and overestimate them for downward ones, so-called trend-damping. Events in a time series can be experienced sequentially, or they can also be retrospectively viewed simultaneously, not experienced individually in real time. In one experiment, we studied the influence of (...) presentation mode on two sorts of judgment: predictions of the next event and estimation of the average value of all the events in the presented series. Participants' responses in dynamic mode were anchored on more recent events than in static mode for all types of judgment but with different consequences; hence, dynamic presentation improved prediction accuracy, but not estimation. These results are not anticipated by existing theoretical accounts; we develop and present an agent-based model—the adaptive anchoring model —to account for the difference between processing sequences of dynamically and statically presented stimuli. ADAM captures how variation in presentation mode produces variation in responses in both forecasting and judgment tasks. ADAM's model predictions for the forecasting and judgment tasks fit better with the response data than a linear-regression time series model. Moreover, ADAM outperformed autoregressive-integrated-moving-average and exponential-smoothing models, while neither of these models accounts for people's responses on the average estimation task.

Advancing the reductionist conviction that biology must be in agreement with the assumptions of reductive physicalism (the upward hierarchy of causal powers, the upward fixing of facts concerning biological levels) A. Rosenberg argues that downward causation is ontologically incoherent and that it comes into play only when we are ignorant of the details of biological phenomena. Moreover, in his view, a careful look at relevant details of biological explanations will reveal the basic molecular level that characterizes biological systems, defined (...) by wholly physical properties, e.g., geometrical structures of molecular aggregates (cells). In response, we argue that contrary to his expectations one cannot infer reductionist assumptions even from detailed biological explanations that invoke the molecular level, as interlevel causal reciprocity is essential to these explanations. Recent very detailed explanations that concern the structure and function of chromatin—the intricacies of supposedly basic molecular level—demonstrate this. They show that what seem to be basic physical parameters extend into a more general biological context, thus rendering elusive the concepts of the basic level and causal hierarchy postulated by the reductionists. In fact, relevant phenomena are defined across levels by entangled, extended parameters. Nor can the biological context be explained away by basic physical parameters defining molecular level shaped by evolution as a physical process. Reductionists claim otherwise only because they overlook the evolutionary significance of initial conditions best defined in terms of extended biological parameters. Perhaps the reductionist assumptions (as well as assumptions that postulate any particular levels as causally fundamental) cannot be inferred from biological explanations because biology aims at manipulating organisms rather than producing explanations that meet the coherence requirements of general ontological models. Or possibly the assumptions of an ontology not based on the concept of causal powers stratified across levels can be inferred from biological explanations. The incoherence of downward causation is inevitable, given reductionist assumptions, but an ontological alternative might avoid this. We outline desiderata for the treatment of levels and properties that realize interlevel causation in such an ontology. (shrink)

In some previous work, I tried to give a concept-based account of the nature of our entitlement to certain very basic inferences (see the papers in Part III of Boghossian 2008b). In this previous work, I took it for granted, along with many other philosophers, that we understood well enough what it is for a person to infer. In this paper, I turn to thinking about the nature of inference itself. This topic is of great interest in its own right (...) and surprisingly understudied by philosophers. A correct understanding of inference promises to shed light on a number of important topics. In particular, it threatens to undermine the sort of concept-based story about entitlement to which I had previously been attracted. (shrink)

Eliminative materialism is the thesis that our common-sense conception of psychological phenomena constitutes a radically false theory, a theory so fundamentally defective that both the principles and the ontology of that theory will eventually be displaced, rather than smoothly reduced, by completed neuroscience. Our mutual understanding and even our introspection may then be reconstituted within the conceptual framework of completed neuroscience, a theory we may expect to be more powerful by far than the common-sense psychology it displaces, and more substantially (...) integrated within physical science generally. My purpose in this paper is to explore these projections, especially as they bear on (1) the principal elements of common-sense psychology: the propositional attitudes (beliefs, desires, etc.), and (2) the conception of rationality in which these elements figure.

JOURNAL OF THE HISTORY OF PHILOSOPHY PRIZE for the best published book in the history of philosophy [Awarded in 2010] _______________ -/- Although it is widely recognized that David Hume's A Treatise of Human Nature (1739-40) belongs among the greatest works of philosophy, there is little agreement about the correct way to interpret his fundamental intentions. It is an established orthodoxy among almost all commentators that skepticism and naturalism are the two dominant themes in this work. The difficulty has been, (...) however, that Hume's skeptical arguments and commitments appear to undermine and discredit his naturalistic ambition to contribute to "the science of man". This schism appears to leave his entire project broken-backed. The solution to this riddle depends on challenging another, closely related, point of orthodoxy: namely, that before Hume published the Treatise he removed almost all material concerned with problems of religion. Russell argues, contrary to this view, that irreligious aims and objectives are fundamental to the Treatise and account for its underlying unity and coherence. It is Hume's basic anti-Christian aims and objectives that serve to shape and direct both his skeptical and naturalistic commitments. When Hume's arguments are viewed from this perspective we can solve, not only puzzles arising from his discussion of various specific issues, we can also explain the intimate and intricate connections that hold his entire project together. This "irreligious" interpretation provides a comprehensive fresh account of the nature of Hume's fundamental aims and ambitions in the Treatise. It also presents a radically different picture of the way in which Hume's project was rooted in the debates and controversies of his own time, placing the Treatise in an irreligious or anti-Chrisitan philosophical tradition that includes Hobbes, Spinoza and freethinking followers. Considered in these terms, Hume's Treatise constitutes the crowning achievement of the Radical Enlightenment. (shrink)

In this chapter, we analyze the relationships between the Internet and its users in terms of situated cognition theory. We first argue that the Internet is a new kind of cognitive ecology, providing almost constant access to a vast amount of digital information that is increasingly more integrated into our cognitive routines. We then briefly introduce situated cognition theory and its species of embedded, embodied, extended, distributed and collective cognition. Having thus set the stage, we begin by taking an embedded (...) cognition view and analyze how the Internet aids certain cognitive tasks. After that, we conceptualize how the Internet enables new kinds of embodied interaction, extends certain aspects of our embodiment, and examine how wearable technologies that monitor physiological, behavioral and contextual states transform the embodied self. On the basis of the degree of cognitive integration between a user and Internet resource, we then look at how and when the Internet extends our cognitive processes. We end this chapter with a discussion of distributed and collective cognition as facilitated by the Internet. (shrink)

Supporters of G.W.F. Hegel's philosophy have largely shied away from relating his logic to modern symbolic or mathematical approaches. While it has predominantly been the non-Greek discipline of algebra that has informed modern mathematical logic, philosopher Paul Redding argues that the approaches of Plato and Aristotle to logic were deeply shaped by the arithmetic and geometry of classical Greek culture. And by ignoring the fact that Hegel's logic also has this deep mathematical dimension, conventional Hegelians have missed some of (...) Hegel's greatest insights. In Conceptual Harmonies, Redding develops an account of Hegel's logic against a classical and modern historical background that is rarely considered. He stresses Hegel's attention to the Platonic background of Aristotle's original syllogistic and beyond. He then links these Platonic elements to Leibniz's modern revitalization of the logical tradition and then to new forms of algebraic geometry emerging in Hegel's lifetime. Redding thereby reestablishes aspects of Hegel's philosophy that are essential if Hegel is to be taken as a thinker relevant not only to contemporary philosophy, but also to current philosophical conceptions of logic.

For over twenty years, Paul Weithman has explored the thought of John Rawls to ask how liberalism can secure the principled allegiance of those people whom Rawls called 'citizens of faith'. This volume brings together ten of his major essays, which reflect on the task and political character of political philosophy, the ways in which liberalism does and does not privatize religion, the role of liberal legitimacy in Rawls's theory, and the requirements of public reason. The essays reveal Rawls (...) as a thinker deeply engaged with political and existential questions that trouble citizens of faith, and explore how - in firm opposition to political realism - he tries to show that the possibility of liberal democracy and the natural goodness of humanity are objects of reasonable faith. The volume will be of interest to political philosophers, political theorists, moral theologians, and religious ethicists. (shrink)

Logic has acquired a reputation for difficulty, perhaps because many of the approaches adopted have been more suitable for mathematicians than computer scientists. This book shows that the subject is not inherently difficult and that the connections between logic and declarative language are straightforward. Many exercises have been included in the hope that these will lead to a much greater confidence in manual proofs, therefore leading to a greater confidence in automated proofs.

The proteins encoded by the ras proto‐oncogenes play critical roles in normal cellular growth, differentiation and development in addition to their potential for malignant transformation. Several proteins that are involved in the control of the activity of p21ras have now been characterised. p120GAP stimulates the GTPase activity of p21ras and hence acts as a negative regulator of ras proteins. It may be controlled by tyrosine phosphorylation or association with tyrosine phosphorylated proteins. The neurofibromatosis type 1 (NF 1) gene also encodes (...) a potential GTPase activating protein which is likely to be subject to a different control mechanism. Guanosine nucleotide exchange factors for p21ras have now been identified: these may be positive regulators of ras protein function. It appears that p21ras is subject to rapid regulation by several distinct mechanisms which are likely to vary in different cell types; the ras proteins are thereby able to act as very sensitive cellular monitors of the extracellular environment.

Schoenflies point groups are presented in terms of spatial partitions and Laue classes based on abstract groups. A much simpler system using only a minimal set of generators for three dimensional groups is then presented in the same form. This simplified treatment allows group operations of a given Laue class to be correlated to a greatly simplified Mulliken-style notation for irreducible representations of that class. Transformation matrix representations of point groups in the simplified style can then be manipulated according to (...) their position in the class or to their sub-groups in very clear procedures. Simple rules can replace the large numbers of tables necessary in the Schoenflies approach. Some applications of the method are described. (shrink)

According to the subset account of realization, a property, F, is realized by another property, G, whenever F is individuated by a non-empty proper subset of the causal powers by which G is individuated (and F is not a conjunctive property of which G is a conjunct). This account is especially attractive because it seems both to explain the way in which realized properties are nothing over and above their realizers, and to provide for the causal efficacy of realized properties. (...) It therefore seems to provide a way around the causal exclusion problem. There is reason to doubt, however, that the subset account can achieve both tasks. The problem arises when we look closely at the relation between properties and causal powers, specifically, at the idea that properties confer powers on the things that have them. If realizers are to be ontically prior to what they realize, then we must regard the conferral of powers by properties as a substantive relation of determination. This relation of conferral is at the heart of a kind of exclusion problem, analogous to the familiar causal exclusion problem. I argue that the subset account cannot adequately answer this new exclusion problem, and is for that reason ill-suited to be the backbone of a non-reductive physicalism. (shrink)

Although thinkers of the past might have started from presumptions of fundamental difference and inequality between (say) the genders, or people of different races, this is no longer the case. At least in mainstream political philosophy, we are all now presumed to be, in some fundamental sense, basic equals. Of course, what follows from this putative fact of basic equality remains enormously controversial: liberals, libertarians, conservatives, Marxists, republicans, and so on, continue to disagree vigorously with each other, despite all presupposing (...) some kind of basic equality. They may argue about who gets what, how much, and why, but the starting point - that all people are in some sense deserving of prima facie equal consideration - has become an axiom of our moral and political thinking. But why? Why are we basic equals? The trouble is that as soon as one asks for an explanation of this foundational premise, it begins to look shaky. After all, on any conceivable metric human beings are notably unequal, and often to striking degrees. Philosophers in this area tend to talk of equal worth, but often without trying to specify what exactly that means. Philosophically, basic equality is neither acceptable nor rejectable. It is not rejectable because we appear to be, as a matter of fact, profoundly committed to the truth of the claim that we are all one another's basic equals. But to the extent that there appear to be no philosophical arguments for believing in the truth of basic equality, it is not acceptable either. The aim of this book is to try and show why basic equality is acceptable. To do so, however, it will also contend that we need to approach the question rather differently to how it has mostly been handled so far. What's required is an exercise in what Bernard Williams called 'impure philosophy': it must include insights from other areas of human intellectual endeavour, whether psychology and history or even what we learn from how we go about practicing basic equality in our collective lives.

Free Will & The Tragic Predicament : Making Sense of Williams -/- The discussion in this paper aims to make better sense of free will and moral responsibility by way of making sense of Bernard Williams’ significant and substantial contribution to this subject. Williams’ fundamental objective is to vindicate moral responsibility by way of freeing it from the distortions and misrepresentations imposed on it by “the morality system”. What Williams rejects, in particular, are the efforts of “morality” to further “deepen” (...) or “refine” the notion of the voluntary, with a view to securing “ultimate justice”. It is these aims and aspirations, he argues, that take us to the precipice of scepticism. In Shame and Necessity (1993) Williams advances a vindicatory genealogy that unmasks the “illusions” and “fantasies” of our current ethical ideas as they relate to agency and responsibility. What we are then left with is the task of “recasting our ethical conceptions” . It is here that Williams is especially insistent on the importance and value of historical consciousness and reflection. The role of our reflections about the Greeks and tragedy is precisely to show that in order to move forward, into the future, we need to first look back at where we have come from. The value of these “untimely” observations is that they provide us with alternatives and options that we might otherwise lack. What we discover, when we consider the Greeks, is their commitment to a “pessimism of strength” that rests on rejecting scepticism. It is this two-sided perspective on our ethical predicament that delivers a more truthful account of our human situation, one that will help us discard those illusions and fantasies of "morality" that we are “better off” without. An account of this kind refuses to accept an optimism that insists that any form of responsible ethical life must be one that is immune to the influence of luck and fate. This is the fundamental lesson that we can learn from the ancient Greeks and that Williams seeks to “recover” for us. (shrink)

Ricoeur’s theory of productive imagination in previously unpublished lectures. The eminent philosopher Paul Ricoeur was devoted to the imagination. These previously unpublished lectures offer Ricoeur’s most significant and sustained reflections on creativity as he builds a new theory of imagination through close examination, moving from Aristotle, Pascal, Spinoza, Hume, and Kant to Ryle, Price, Wittgenstein, Husserl, and Sartre. These thinkers, he contends, underestimate humanity’s creative capacity. While the Western tradition generally views imagination as derived from the reproductive example of (...) the image, Ricoeur develops a theory about the mind’s power to produce new realities. Modeled most clearly in fiction, this productive imagination, Ricoeur argues, is available across conceptual domains. His theory provocatively suggests that we are not constrained by existing political, social, and scientific structures. Rather, our imaginations have the power to break through our conceptual horizons and remake the world. (shrink)

This is a book about the Hilbert space formulation of quantum mechanics and its measurement theory. It contains a synopsis of what became of the Mathematical Foundations of Quantum Mechanics since von Neumann's classic treatise with this title. Fundamental non-classical features of quantum mechanics-indeterminacy and incompatibility of observables, unavoidable measurement disturbance, entanglement, nonlocality-are explicated and analysed using the tools of operational quantum theory. The book is divided into four parts: 1. Mathematics provides a systematic exposition of the Hilbert space and (...) operator theoretic tools and relevant measure and integration theory leading to the Naimark and Stinespring dilation theorems; 2. Elements develops the basic concepts of quantum mechanics and measurement theory with a focus on the notion of approximate joint measurability; 3. Realisations offers in-depth studies of the fundamental observables of quantum mechanics and some of their measurement implementations; and 4. Foundations discusses a selection of foundational topics (quantum-classical contrast, Bell nonlocality, measurement limitations, measurement problem, operational axioms) from a measurement theoretic perspective. The book is addressed to physicists, mathematicians and philosophers of physics with an interest in the mathematical and conceptual foundations of quantum physics, specifically from the perspective of measurement theory.

De Marco and colleagues claim that the standard account of invasiveness as commonly encountered ‘...does not capture all uses of the term in relation to medical interventions 1 ’. This is open to challenge. Their first example is ‘non-invasive prenatal testing’. Because it involves puncturing the skin to obtain blood, De Marco _et al_ take this as an example of how an incision or insertion is not sufficient to make an intervention invasive; here is a procedure that involves an incision, (...) but it is regarded as non-invasive. However, this ignores the context, and the term should really be understood in reference to the fetus. It is hard to believe healthcare professionals regard taking blood to measure, for example, ferritin levels as invasive but taking blood to look for fragments of fetal DNA as not. If anyone uses the term thinking it is not invasive to the mother, the... (shrink)

David Hume (1711-1776) is widely recognized as one of the most influential and significant critics of religion in the history of philosophy. There remains, nevertheless, considerable disagreement about the exact nature of his views. According to some, he was a skeptic who regarded all conjectures relating to religious hypotheses to be beyond the scope of human understanding – he neither affirmed nor denied these conjectures. Others read him as embracing a highly refined form of “true religion” of some kind. On (...) the other side of this spectrum, it is claimed that Hume was committed to atheism, although due to social conditions at the time, this had to be (thinly) concealed or masked. The aim of this article is to provide an overview of Hume’s core concerns and arguments on this subject and to provide the reader with a framework for interpreting and assessing his various contributions.
