The early withdrawal of students from healthcare education programmes, particularly nursing, is an international concern and, despite considerable investment, retention rates have remained stagnant. Here, a regional study of healthcare student retention is used as an example to frame the challenge of student attrition using a concept from policy development, wicked problem theory. This approach allows the consideration of student attrition as a complex problem derived from the interactions of many interrelated factors, avoiding the pitfalls of small‐scale interventions and over‐simplistic (...) assumptions of cause and effect. A conceptual framework is proposed to provide an approach to developing actions to reduce recurrent investment in interventions that have previously proved ineffective at large scale. We discuss how improvements could be achieved through integrated stakeholder involvement and acceptance of the wicked nature of attrition as a complex and ongoing problem. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aquinas on the Beginning and End of Human Life by Fabrizio AmeriniJohn LanganReview: Fabrizio Amerini, Aquinas on the Beginning and End of Human Life, trans. Mark Henninger, Harvard University Press, 2013The ongoing and apparently interminable debate over the moral and legal status of abortion has come over the years to resemble the Western front in World War I, with two contending armies facing each other with limited (...) maneuvering room, familiar and overused weapons, periodic artillery barrages, increasing casualties, not much new to report, and a deadly ‘no man’s land’ between them in which virtually nothing survives. Against the gloomy monotony of the abortion wars, in which reductivist accounts of the opponents’ views and repetitious restatements of familiar and cherished views predominate, this book by Fabrizio Amerini, a professor of philosophy at the University of Parma, appears as a refreshing surprise. It is surprising for a number of reasons, which I shall present later. But its refreshing character comes primarily from its moderate tone and the care with which its arguments are presented. Amerini is clearly familiar with the Catholic tradition on abortion and euthanasia; he is respectful of this tradition, which he does not directly challenge, but his sense of scholarly integrity prevents him from simply presenting Aquinas as a defender and synthesizer of all the positions championed in that tradition or by its papal custodians. He has an impressive command of the relevant texts in Aquinas and the Fathers of the Church, which he joins with a scrupulous style of [End Page E-103] philosophical argument which has an affinity with the clarifying labors of G. E. Moore in the early days of analytic moral philosophy. The result is not easy reading, but the reader can be confident that the desire to score rhetorical points and political victories will not distort the philosophical and historical analysis. The book is intended primarily for those who can benefit from careful scholarship, but it should be instructive for all who regard the questions of abortion and euthanasia as genuinely difficult and as deserving our best intellectual efforts.The most important surprise is Amerini’s focus on the issue of delayed versus immediate hominization in the development from embryo to complete human being. Since Pius IX in 1867, the Vatican has insisted that from the moment of conception the embryo becomes a human person whose life is sacred and deserves full protection. This view is ordinarily discussed as ‘immediate hominization’. In Amerini’s view, the embryo lacks the development and differentiation of organs which would enable it to have a sustainable potentiality to perform the acts which are proper to a human person, particularly reasoning and choosing. In the Vatican’s view, the soul is immediately infused by God, though it obviously requires many years of development before it is able to function as a complete and distinct human person. Amerini regards this position as untenable within Aquinas’s metaphysical system and finds in Aquinas’s own texts evidence that he teaches a discontinuous process in fetal life. Amerini regards the insistence on immediate hominization as an arbitrary effort to maintain an absolute uniformity of moral status in all the stages of embryonic and fetal life. He sees the Vatican’s position as leading to an equation of abortion and homicide which he regards as unjustified. He does, however, affirm that there is an identity of subject running from the embryo to the developed person and also that this grounds an ethic of respect for life in all of its stages. The practical conclusions in bioethics he would draw from this position “could allow space for a judicious and discriminating ethical evaluation of individual cases,” as he puts the matter in the concluding sentence of the book.Other surprises are the author’s discovering from a careful reading of Aquinas’s texts that he taught a progressive plurality of substantial forms in the development of the embryo. For Aquinas, it is the substantial form which answers the question about what sort of being the object of our inquiry is. In the case of human persons, the substantial form is the soul, which includes the intellectual properties of... (shrink)

On the basis of careful textual exegesis and philosophical analysis, and contrary to the received view, Mark R. Wheeler demonstrates that Aristotle presents and systematically explicates his definition of the essence of the truth in the Metaphysics. Aristotle states the nominal definitions of the terms "truth" and "falsehood" as part of his arguments in defense of the logical axioms. These nominal definitions express conceptions of truth and falsehood his philosophical opponents would have recognized and accepted in the context of (...) dialectical argument. On the basis of these nominal definitions, Aristotle develops his definitions of the essences of truth and falsehood--his "real" definitions of truth and falsehood. Aristotle's methodical exposition of his essential definitions of truth and falsehood in the Metaphysics serves as a well-developed example of how his philosophical inquiry starts with nominal definitions and ends with real definitions. Wheeler also argues for the novel claim that Aristotle defines the most fundamental kind of truth in terms of accurate measurement. Aristotle's metrical conception of truth serves as the theoretical basis for specifying the truth conditions of various assertions, for identifying the sorts of beings implicated in these truth conditions, and for explaining the nature of approximate truth and falsehood. Far from offering us a minimal account of truth, Wheeler shows how Aristotle offers us a sophisticated and metrical theory of truth. (shrink)

One problem facing Hockney and Falco is the lack of evidence among optical sources to support their claim that artists used image-projection by the early 1400s. After all, if quattrocento artists knew about image-projection, they must have learned about it from experts in the field, and no one was more expert at the time than Perspectivist opticians. As I argue in this paper, however, Perspectivist reflection-analysis posed certain theoretical and conceptual constraints that would have prevented Perspectivist opticians from recognizing, much (...) less understanding, image-projection. Their silence on this matter is therefore not evidence against the Hockney-Falco thesis. (shrink)

In ancient China, a revered Taoist sage named Zhuangzi told many parables. In Existential Psychology and the Way of the Tao, a selection of these parables will be featured. Following each parable, an eminent existential psychologist will share a personal and scholarly reflection on the meaning and relevance of the parable for psychotherapy and contemporary life. The major tenets of Zhuangzi's philosophy are featured. Taoist concepts of emptiness, stillness, Wu Wei (i.e. intentional non-intentionality), epistemology, dreams and the nature of reality, (...) character building in the midst of pain, meaning and the centrality of relationships, authenticity, self-care, the freedom that can come from one's willingness to confront death, spiritual freedom, and gradations of therapeutic care are topics highlighted in this book.

In this essay, I give an analysis of the account of non-being in the Weltalter, focusing on the ways in which this account reflects Schelling’s new ontology of revelation. I begin by discussing the connection between non-being and the fundamental distinction between the principles in God. I then turn to the relationship of non-being to being in the Weltalter and show how a new meaning of being allows Schelling to distinguish non-being from nothing. The new meaning of being also makes (...) possible a distinction between essential non-being and de facto non-being; this distinction allows for the temporal sequence of revelation and the possibility of evil. I conclude by showing the implications of Schelling’s theory of non-being for his understanding of creation. (shrink)

Stereological techniques allow biologists to create quantitative, three-dimensional descriptions of biological structures from two- dimensional images of tissue viewed under the microscope. For example, they can accurately estimate the size of a particular organelle, the total length of a mass of capillaries, or the number of neurons or synapses in a particular region of the brain. This book provides a practical guide to designing and critically evaluating stereological studies of the nervous system and other tissues. It explains the basic concepts (...) behind design-based stereology and how to get started. Also included are detailed descriptions of how to prepare tissue appropriately, perform pilot studies and decide on the appropriate sampling strategy, and account for phenomena such as tissue shrinkage. Numerous examples of applications of stereological methods that are applicable to studies of the central system and a wide variety of other tissues are explained. The book is therefore essential reading for neurobiologists and cell biologists interested in generating accurate representations of cell and tissue architecture. (shrink)

What can we learn about the nature of technology by studying practices of maintenance and repair? This volume addresses this question by bringing together scholarship from philosophers of technology working at the forefront of this emerging and exciting topic. -/- The chapters in this volume explore how attending to maintenance and repair can challenge and complement existing ways of thinking about technology focused on use and design and introduce new philosophical perspectives on the relationship between technology, time and human practice. (...) They examine the significance of maintenance and repair practices at different scales in relation to a diverse range of philosophical traditions and a wide variety of technologies, from urban infrastructure such as bridges and buildings to data technologies such as servers and software systems. Together, the contributions highlight common themes in the philosophical study of maintenance, including the role of skill, the significance of social values and the potential of these practices to transform the technologies to which they are applied. By reflecting on the different ways in which we keep technologies going, from the devices we use in our homes to the large technical systems which surround us, this volume reveals the philosophical significance of practices of maintenance, not only as a source of new insights but also as a resource for enriching our understanding of a variety of existing topics in philosophy. -/- Maintenance and Philosophy of Technology will appeal to scholars and advanced students working in philosophy of technology, philosophy of engineering and science & technology studies.

Virtues are dispositions that make their bearers admirable. Dispositions can be studied scientifically by systematically varying whether their alleged bearers are in (or take themselves to be in) the dispositions' eliciting conditions. In recent decades, empirically-minded philosophers looked to social and personality psychology to study the extent to which ordinary humans embody dispositions traditionally considered admirable in the Aristotelian tradition. This led some to conclude that virtues are not attainable ideals, and that we should focus our ethical reflection and efforts (...) more on jerry-rigging our environments than on improving our characters. Most virtue ethicists resisted this reorientation. However, much of the scientific evidence on which the controversy was based has failed to replicate, raising the question of how much faith we should place in methodologically suspect studies. In this paper, I assess the state of the debate and recommend best practices for a renewed interdisciplinary investigation of virtues and vices in which philosophical expertise related to conceptualization and theorizing is essentially intertwined with scientific expertise related to operationalization, measurement, and statistics.

Moral theories usually aspire to be explanatory – to tell us why something is wrong, why it is good, or why you ought to do it. So it is worth knowing how moral explanations differ, if they do, from explanations of other things. This paper uncovers a common unarticulated theory about how normative explanations must work – that they must follow what I call the Standard Model. Though the Standard Model Theory has many implications, in this paper I focus primarily (...) on only one. It plays a crucial role in an argument originally due to Cudworth that has been widely held to conclusively establish that voluntaristic ethical theories are incoherent. But if Cudworth’s argument works, then so would similar arguments against many other moral theories. All of these theories therefore need a different model for how normative explanations can work. So I also motivate and sketch one such alternative model. The result enables us to make progress in evaluating the prospects for a successful reductive view about the normative. (shrink)

Together again for the first time, Marx and Durkheim join forces in the pages of Disintegration: Bad Love, Collective Suicide, and the Idols of Imperial Twilight for a dialectical exploration of the moral economy of neoliberalism, animated, as it is not only by the capitalist chase for surplus value, but also by an immortal vortex of sacred powers. Classical sociology and psychoanalysis are reconstituted within Hegelian social ontology and dialectical method that differentiates between the ephemeral and free and the eternal (...) and fixed aspects of modern life.

Even given the final truths of what is right and wrong, good and bad, ethics is not complete. For one may yet ask “Why should I be moral?” Of course, we have no prior assurance that it will be possible to provide a non-moral and justifiable answer to the rational and self-interested person. Nevertheless, I claim that reasons for being moral can be provided even for the rational, self-interested, and remorseless individual who knows he will not be caught. In defending (...) my claim I will draw on empirical data from recent social psychology and game theory. Actual human selves are malleable in a number of ways. I will show that it is rational for the self-interested person to modify selves in such a way that moral actions are increasingly preferred. Specifically, I will argue that it is in one’s rational self-interest to enhance empathy in others and future selves in such a way that for increasing numbers other-injury becomes a component of self-injury, and other-benefit becomes a component of self-benefit. This will allow a linkage to be drawn from rational and self-interested action to moral action. The development of this theory will begin by distinguishing my approach from that of Gauthier, then three interpretations of the “Why be moral?” question will be delineated, next the decision theoretic components of my account will be presented, and finally the role of empathy will be considered in detail.

At first glance, Schopenhauer’s account of human freedom looks strikingly similar to Schelling’s account of formal freedom in the Freiheitsschrift. Despite the clear similarities, I argue that there is a decisive difference between the two accounts—a difference that has to do with the ultimate grounding of freedom. For Schelling, the intelligible deed is a radical self-grounding of the eternal essence of the human being. For Schopenhauer, the eternal essence of the human being is groundless. Moreover, I argue that this difference (...) has decisive consequences for two sets of issues. On the one hand, Schelling’s concept of self-grounding allows him to preserve the universal application of the principle of ground. On the other hand, self-grounding is the only way that human beings can be responsible for who they are. Schelling thus anticipates a key insight of Galen Strawson: ultimate moral responsibility is only possible for a causa sui. (shrink)

In the fifth book of his De aspectibus, the medieval Latin version of Ibn al-Haythamb al-Manir, Alhacen undertakes to determine precisely where a given ray of light will reflect to a given center of sight from a variety of convex and concave mirrors based on circular sections. As applied specifically to convex and concave spherical mirrors, this problem exercised several seventeenth-century thinkers, Christiaan Huygens foremost among them, and in that context it soon became known as Alhazens solution (or solutions) of (...) this problem is deficient in comparison to that of Huygens and later mathematicians. It is my purpose in this paper to show by reconstruction that in fact, far from deficient in any absolute sense, Alhacen’s approach to this problem was remarkably ingenious and elegant in its conceptual simplicity.

From the late thirteenth to the early seventeenth century, the process of visual imaging was understood in the Latin West as an essentially subjective act initiated by the eye and completed by the brain. The crystalline lens took center stage in this act, its role determined by its peculiar physical and sensitive capacities. As a physical body, on the one hand, it was disposed to accept the physical impressions of light and color radiating to it from external objects. As a (...) sensitive body, on the other hand, it was enabled by the visual spirit flowing to it from the brain to feel those impressions visually. Acting as a sentient selector of visual information, the lens transformed the brute physical impressions of light and color into visual impressions. These, in turn, gave rise to perceptual “depictions” that were passed back along the stream of visual spirits to the brain. Known in Scholastic parlance as “intentional species,” these depictions served as virtual representations of their generating objects. As such, they provided the wherewithal not only for perception, but also for conception and cognition. (shrink)

That the medieval Latin version of Ibn al-Haytham's Kitāb al-Manā[zdotu]ir was translated into Italian in the fourteenth century has been known for well over a century. Recent studies have shown that this translation, which is contained in Vat. Lat. 4595, was instrumental in the composition of Lorenzo Ghiberti's Commentario terzo on art. Some eight years ago, the author of the present article tentatively identified the actual manuscript-source of that translation as MS Royal 12.G.7, which is currently held in the British (...) Library. This study establishes beyond reasonable doubt that his tentative identification was correct: MS Royal 12.G.7 is indeed the Latin source for the Italian translation in Vat. Lat. 4595.

This paper considers the connection between the three-place relation, R is a reason for X to do A and the two-place relation, R is a reason to do A. I consider three views on which the former is to be analyzed in terms of the latter. I argue that these views are widely held, and explain the role that they play in motivating interesting substantive ethical theories. But I reject them in favor of a more obvious analysis, which goes the (...) other way around. (shrink)

Gossip is often serious business, not idle chitchat. Gossip allows those oppressed to privately name their oppressors as a warning to others. Of course, gossip can be in error. The speaker may be lying or merely have lacked sufficient evidence. Bias can also make those who hear the gossip more or less likely to believe the gossip. By examining the social functions of gossip and considering the differences in power dynamics in which gossip can occur, we contend that gossip may (...) be not only permissible but virtuous, both as the only reasonable recourse available and as a means of resistance against oppression.

This paper presents five studies on the development and validation of a scale of intellectual humility. This scale captures cognitive, affective, behavioral, and motivational components of the construct that have been identified by various philosophers in their conceptual analyses of intellectual humility. We find that intellectual humility has four core dimensions: Open-mindedness (versus Arrogance), Intellectual Modesty (versus Vanity), Corrigibility (versus Fragility), and Engagement (versus Boredom). These dimensions display adequate self-informant agreement, and adequate convergent, divergent, and discriminant validity. In particular, Open-mindedness (...) adds predictive power beyond the Big Six for an objective behavioral measure of intellectual humility, and Intellectual Modesty is uniquely related to Narcissism. We find that a similar factor structure emerges in Germanophone participants, giving initial evidence for the model’s cross-cultural generalizability. (shrink)

Selected as a Financial Times Best Book of 2013Governments today in both Europe and the United States have succeeded in casting government spending as reckless wastefulness that has made the economy worse. In contrast, they have advanced a policy of draconian budget cuts--austerity--to solve the financial crisis. We are told that we have all lived beyond our means and now need to tighten our belts. This view conveniently forgets where all that debt came from. Not from an orgy of government (...) spending, but as the direct result of bailing out, recapitalizing, and adding liquidity to the broken banking system. Through these actions private debt was rechristened as government debt while those responsible for generating it walked away scot free, placing the blame on the state, and the burden on the taxpayer. That burden now takes the form of a global turn to austerity, the policy of reducing domestic wages and prices to restore competitiveness and balance the budget. The problem, according to political economist Mark Blyth, is that austerity is a very dangerous idea. First of all, it doesn't work. As the past four years and countless historical examples from the last 100 years show, while it makes sense for any one state to try and cut its way to growth, it simply cannot work when all states try it simultaneously: all we do is shrink the economy. In the worst case, austerity policies worsened the Great Depression and created the conditions for seizures of power by the forces responsible for the Second World War: the Nazis and the Japanese military establishment. As Blyth amply demonstrates, the arguments for austerity are tenuous and the evidence thin. Rather than expanding growth and opportunity, the repeated revival of this dead economic idea has almost always led to low growth along with increases in wealth and income inequality. Austerity demolishes the conventional wisdom, marshaling an army of facts to demand that we austerity for what it is, and what it costs us. (shrink)

In his arguments that science itself can answer moral questions, Sam Harris often appeals to our intuitions about the badness of suffering. If we share these intuitions, Harris argues, we’ve taken a significant step in conceding to a basically utilitarian worldview. In this chapter, I critically assess Harris’ arguments and find them deeply wanting.

In the first section I outline the theory of abstraction, discussing first its con- ceptual basis, then its psychological-epistemological basis, and last its causal basis. My purpose throughout is to show how these bases, and thus the theory itself, were not only paramountly Aristotelian, but also eminently sensible. In the second section I draw the perspectivist account of vision within the bounds of the theory of abstraction and show stage by stage how that account unfolds coherently within those bounds. This (...) procedure should make clear that what the perspecti- vists actually offered was less a scientific theory of light or vision than a scientifi- cally justified world view. (shrink)

Nietzsche scholars have developed an interest in his use of “thick” moral psychological concepts such as virtues and emotions. This development coincides with a renewed interest among both philosophers and social scientists in virtues, the emotions, and moral psychology more generally. Contemporary work in empirical moral psychology posits contempt and disgust as both basic emotions and moral foundations of normative codes. While virtues can be individuated in various ways, one attractive principle of individuation is to index them to characteristic emotions (...) and the patterns of behavior those emotions motivate. Despite the surge in attention to Nietzsche’s use of emotions, the literature has tended to lump all emotional states together. In this paper, I argue that what Nietzsche calls the pathos of distance is best understood as the virtue associated with both contempt and disgust. I conclude with a discussion of the bleak prospects for a Nietzschean democratic ethos. (shrink)

In a vivid re-creation of late sixteenth-century Flemish intellectual life, Mark Morford explores the intertwined careers of one of the period's most influential thinkers and one of its most original artists: Justus Lipsius and Peter Paul Rubens. He investigates the scholarship of Lipsius (1547-1606), whose revival of Roman Stoicism guided his contemporaries during the revolt of the Netherlands from the rule of Spain and whose teaching prepared future leaders in church and state. Maintaining that Lipsius' thought reached Peter Paul (...) Rubens through his brother, Philip Rubens, Morford analyzes the artist's use of Stoic philosophical and political allegory, beginning with his painting The Four Philosophers. This book discusses the revival of Stoicism in northern Europe, focusing on Lipsius' editions of Tacitus and Seneca, his widely read handbooks on constancy and politics, and his interaction with leading scholars and public figures. As his letters reveal, Lipsius was inconsistent in his life and unsuccessful in reconciling Stoicism with Catholic doctrine; Rubens, although at first sympathetic to the doctrines of Lipsius, is shown to have later transcended their limitations.

What is morality? How many moral values are there? And what are they? According to the theory of morality-as-cooperation, morality is a collection of biological and cultural solutions to the problems of cooperation recurrent in human social life. This theory predicts that there will be as many different types of morality as there are different types of cooperation. Previous research, drawing on evolutionary game theory, has identified at least seven different types of cooperation, and used them to explain seven different (...) types of morality: family values, group loyalty, reciprocity, heroism, deference, fairness and property rights. Here we explore the conjecture that these simple moral ‘elements’ combine to form a much larger number of more complex moral ‘molecules’, and that as such morality is a combinatorial system. For each combination of two elements, we hypothesise a candidate moral molecule, and successfully locate an example of it in the professional and popular literature. These molecules include: fraternity, blood revenge, family pride, filial piety, gavelkind, primogeniture, friendship, patriotism, tribute, diplomacy, common ownership, honour, confession, turn taking, restitution, modesty, mercy, munificence, arbitration, mendicancy, and queuing. These findings indicate that morality – like many other physical, biological, psychological and cultural systems – is indeed a combinatorial system. Thus morality-as-cooperation provides a principled and powerful theory, that explains why there are many moral values, and successfully predicts what they will be; and it generates a systematic framework that has the potential to explain all moral ideas, possible and actual. Pursuing the many implications of this theory will help to place the study of morality on a more secure scientific footing. (shrink)

The years between 1833 and 1945 fundamentally transformed science’s understanding of the body’s inner senses, revolutionizing fields like philosophy, the social sciences, and cognitive science. In How We Became Sensorimotor, Mark Paterson provides a systematic account of this transformative period, while also demonstrating its substantial implications for current explorations into phenomenology, embodied consciousness, the extended mind, and theories of the sensorimotor, the body, and embodiment. -/- Each chapter of How We Became Sensorimotor takes a particular sense and historicizes its (...) formation by means of recent scientific studies, case studies, or coverage in the media. Ranging among a diverse array of sensations, including balance, fatigue, pain, the “muscle sense,” and what Maurice Merleau-Ponty termed “motricity,” Paterson’s analysis moves outward from the familiar confines of the laboratory to those of the industrial world and even to wild animals and their habitats. He uncovers important stories, such as how forgotten pain measurement schemes transformed criminology, or how Penfield’s outmoded concepts of the sensory and motor homunculi of the brain still mar psychology textbooks. -/- Complete with original archival research featuring illustrations and correspondence, How We Became Sensorimotor shows how the shifting and sometimes contested historical background to our understandings of the senses are being extended even today.

A fundamental fact about human minds is that they are never truly alone: all minds are steeped in situated interaction. That social interaction matters is recognized by any experimentalist who seeks to exclude its influence by studying individuals in isolation. On this view, interaction complicates cognition. Here, we explore the more radical stance that interaction co-constitutes cognition: that we benefit from looking beyond single minds toward cognition as a process involving interacting minds. All around the cognitive sciences, there are approaches (...) that put interaction center stage. Their diverse and pluralistic origins may obscure the fact that collectively, they harbor insights and methods that can respecify foundational assumptions and fuel novel interdisciplinary work. What might the cognitive sciences gain from stronger interactional foundations? This represents, we believe, one of the key questions for the future. Writing as a transdisciplinary collective assembled from across the classic cognitive science hexagon and beyond, we highlight the opportunity for a figure-ground reversal that puts interaction at the heart of cognition. The interactive stance is a way of seeing that deserves to be a key part of the conceptual toolkit of cognitive scientists. (shrink)

In his groundbreaking book, Thin Objects, Linnebo (2018) argues for an account of neo-Fregean abstraction principles and thin existence that does not rely on analyticity or conceptual rules.

Starting from the key argument that - ethically speaking - there is far less difference between humans (...) and animals than has conventionally been allowed, Mark Rowlands goes on to explore and illuminate a host of contemporary issues - from farming and animal experimentation to hunting and the preservation of endangered species. This accessible and readable book will appeal to both students and general readers, giving a fascinating introduction to animal rights - and what matters most about them -- P. 4 of cover. (shrink)

The concept of an operator is used in a variety of practical and theoretical areas. Operators, as both conceptual and physical entities, are found throughout the world as subsystems in nature, the human mind, and the manmade world. Operators, and what they operate, i.e., their substrates, targets, or operands, have a wide variety of forms, functions, and properties. Operators have explicit philosophical significance. On the one hand, they represent important ontological issues of reality. On the other hand, epistemological operators form (...) the basic mechanism of cognition. At the same time, there is no unified theory of the nature and functions of operators. In this work, we elaborate a detailed analysis of operators, which range from the most abstract formal structures and symbols in mathematics and logic to real entities, human and machine, and are responsible for effecting changes at both the individual and collective human levels. Our goal is to find what is common in physical objects called operators and abstract mathematical structures, with the name operator providing foundations for building a unified but flexible theory of operators. The paper concludes with some reflections on functionalism and other philosophical aspects of the ‘operation’ of operators. (shrink)

Written by the 11th-century Spanish Arab, Abh Muhammad ibn MucnOn Twilight and the Rising of Cloudsdh's value of around 52 miles remained standard until the 17th century, when it was revised sharply downward in consideration of atmospheric refraction and barometric studies.

Nietzsche promises to “translate man back into nature,” but it remains unclear what he meant by this and to what extent he succeeded at it. To help come to grips with Nietzsche’s conceptions of drive (Trieb), instinct (Instinkt) and virtue (Tugend and/or Keuschheit), I develop novel digital humanities methods to systematically track his use of these terms, constructing a near-comprehensive catalogue of what he takes these dispositions to be and how he thinks they are related. Nietzsche individuate drives and instincts (...) by the type of actions they motivate. One way in which the “translation” of man back into nature might succeed is through naturalistic explanation and reduction of moral notions such as virtue in terms of amoral, naturalistic notions, such as drives and instincts. I go on to show that this is indeed Nietzsche’s project: for him, a virtue is a well-calibrated drive. Such calibration relates both to the rest of the agent’s psychic economy (her other drives) and to her social context (what’s considered praiseworthy and blameworthy in her community). (shrink)

“Although up to now the [visual] image has been [understood as] a construct of reason,” Kepler observes in the fifth chapter of his Ad Vitellionem Paralipomena, “henceforth the [visible] representations of objects should be considered as paintings [ picturae ] that are actual[ly projected] on paper or some other screen.” While not intended as a historical generalization, this claim nonetheless reflects historical reality. Virtually all visual theorists before Kepler did, in fact, conceive of optical images as subjective, not objective constructs (...) – or, to put it in modern terms, as virtual rather than real entities. By current lights, of course, the distinction between virtual and real images is both obvious and common-place: whereas the latter can be physically projected upon a screen, the former cannot.
