Exegesis, analysis and discussion of an argument deployed by Dana Scott in his 1973 paper ‘Background to Formalization’, rovide an ideal setting for getting clear about some subtleties in the apparently simple idea of conservative extension. There, Scott claimed in respect of two fundamental principles concerning implication that any generalized consequence relation respecting these principles is always extended conservatively by some similarly fundamental principles concerning conjunction and disjunction. This claim appears on the face of it to conflict with cases (...) in the literature in which adding principles governing conjunction or disjunction or both provides a non-conservative extension of the logic to which they are added, even if that logic does satisfy the intuitionistic conditions on implication. We explore the extent to which such cases can be transformed into counterexamples to Scott’s claim. Once one part of this claim is suitably disambiguated, we find no conflict after all, though we also find that Scott occasionally understates what the argument he provides in support of this claim actually establishes. The main goal, apart from getting straight about Scott’s argument, is to give an airing to various issues and distinctions in the general area of conservativity of extensions; as a side benefit, some semantic light will be thrown on a fragmentary intermediate logic of R. A. Bull, which A. N. Prior showed to be extended non-conservatively by the addition of conjunction, governed by the usual axioms. We will see exactly why, despite appearances, this is not a counterexample to Scott’s claim. (shrink)

This chapter examines the pioneering work of Gottfried Wilhelm Leibniz (1646-1716) on various number systems, in particular binary, which he independently invented in the mid-to-late 1670s, and hexadecimal, which he invented in 1679. The chapter begins with the oft-debated question of who may have influenced Leibniz’s invention of binary, though as none of the proposed candidates is plausible I suggest a different hypothesis, that Leibniz initially developed binary notation as a tool to assist his investigations in mathematical problems that were (...) exercising him at the time, namely those concerning the divisibility of composite numbers, primality, and perfect numbers. The chapter then explores Leibniz’s development of binary, his little-known work on binary fractions and expansions, his use of binary as a symbol for creation in his philosophical-theology, and his response to the suggestion that there was a correlation between binary numeration and the hexagrams of the ancient Chinese divinatory text, the Yijing. The chapter then focuses on Leibniz’s work on other number systems, in particular his invention and exploration of hexadecimal as well as his work on duodecimal. The chapter concludes by revealing a hitherto unknown practical application of binary that Leibniz devised in the last year of his life. (shrink)

To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)

Animate vision systems have gaze control mechanisms that can actively position the camera coordinate system in response to physical stimuli. Compared to passive systems, animate systems show that visual computation can be vastly less expensive when considered in the larger context of behavior. The most important visual behavior is the ability to control the direction of gaze. This allows the use of very low resolution imaging that has a high virtual resolution. Using such a system in a controlled way provides (...) additional constraints that dramatically simplify the computations of early vision. Another important behavior is the way the environment “behaves‘. Animate systems under real-time constraints can further reduce their computational burden by using environmental cues that are perspicuous in the local context. A third source of economy is introduced when behaviors are learned. Because errors are rarely fatal, systems using learning algorithms can amortize computational cost over extended periods. Further economies can be achieved when the learning system uses indexical reference, which is a form of dynamic variable binding. Animate vision is a natural way of implementing this dynamic binding.

The cerebral cortex is a rich and diverse structure that is the basis of intelligent behavior. One of the deepest mysteries of the function of cortex is that neural processing times are only about one hundred times as fast as the fastest response times for complex behavior. At the very least, this would seem to indicate that the cortex does massive amounts of parallel computation.This paper explores the hypothesis that an important part of the cortex can be modeled as a (...) connectionist computer that is especially suited for parallel problem solving. The connectionist computer uses a special representation, termed value unit encoding, that represents small subsets of parameters in a way that allows parallel access to many different parameter values. This computer can be thought of as computing hierarchies of sensorimotor invariants. The neural substrate can be interpreted as a commitment to data structures and algorithms that compute invariants fast enough to explain the behavioral response times. A detailed consideration of this model has several implications for the underlying anatomy and physiology. (shrink)

Trust in the doctor-patient relationship is an indispensable structural element for the medical profession. The discourse concerning trust and its importance in the healthcare context, although quite old, elicits increasingly more interest in research, especially for empirical approaches. The importance of trust in the doctor and in the medical profession can be demonstrated by starting from the Christian meaning of illness and medicine ; generally, the patristic sources see medicine and physicians as God’s gifts. T he perception of Christian physicians (...) as dedicated, unselfish and compassionate preservers or restorers of health, always committed to the good of their patients is well known. The model of the Christian physician is a Hippocratic model, of one who seeks the sick so that he may bring relief to them and strengthen them. When illness occurs, Christianity affirms an ethical duty to struggle against sickness, which if unaddressed can lead to death. The moral requirement to care for the health of the body indicates it is appropriate to use healing methods that will enhance health and maintain life. The aim of this paper is to explore the dimensions of the concept of trust in the doctor-patient relationship, by starting from the Christian meaning of illness and of the role of the doctor. The paper presents a number of essential theoretical elements related to trust, as presented in the literature dealing with the doctor-patient relationship: the meaning of trust, its dimensions, its stages of development, its impact, its sources, the patient’s perspectives on trust, the importance of trust for healthcare systems.

In this book, S. A. Lloyd offers a radically new interpretation of Hobbes's laws of nature, revealing them to be not egoistic precepts of personal prudence but rather moral instructions for obtaining the common good.

Much attention has been focused in recent years on the ethical acceptability of physicians receiving gifts from drug companies. Professional guidelines recognize industry gifts as a conflict of interest and establish thresholds prohibiting the exchange of large gifts while expressly allowing for the exchange of small gifts such as pens, note pads, and coffee. Considerable evidence from the social sciences suggests that gifts of negligible value can influence the behavior of the recipient in ways the recipient does not always realize. (...) Policies and guidelines that rely on arbitrary value limits for gift-giving or receipt should be reevaluated. (shrink)

Considerable attention has been paid recently to the gendering of organizations and occupations. Unfortunately, the gendered-organizations approach remains theoretically and empirically underdeveloped, as there have as yet been few clear answers to the question central to the perspective: What does it really mean to say that an organization itself, or a policy, practice, or slot in the hierarchy, is “gendered”? Reviewing literature in the gendered-organizations tradition, the author discusses three of the most common ways the perspective has been applied and (...) argues that all of these definitions pose potential problems for the project of meaningful social and organizational change. The article concludes with some suggestions about how a more useful conception of the gendered organization might be built. (shrink)

The doctrine of double effect, together with other moral principles that appeal to the intentions of moral agents, has come under attack from many directions in recent years, as have a variety of rationales that have been given in favor of it. In this paper, our aim is to develop, defend, and provide a new theoretical rationale for a secular version of the doctrine. Following Quinn (1989), we distinguish between Harmful Direct Agency and Harmful Indirect Agency. We propose the following (...) version of the doctrine: that in cases in which harm must come to some in order to achieve a good (and is the least costly of possible harms necessary), the agent foresees the harm, and all other things are equal, a stronger case is needed to justify Harmful Direct Agency than to justify Harmful Indirect Agency. We distinguish between two Kantian rationales that might be given for the doctrine, a “dependent right” rationale, defended by Quinn, and an “independent right” rationale, which we defend. We argue that the doctrine and the “independent right” rationale for it are not vulnerable to counterexamples or counterproposals, and conclude by drawing implications for the larger debate over whether agents' intentions are in any way relevant to permissibility and obligation.

Nelkin presents a simple and natural account of freedom and moral responsibility which responds to the great variety of challenges to the idea that we are free and responsible, before ultimately reaffirming our conception of ourselves as agents. Making Sense of Freedom and Responsibility begins with a defense of the rational abilities view, according to which one is responsible for an action if and only if one acts with the ability to recognize and act for good reasons. The view is (...) compatibilist -- that is, on the view defended, responsibility is compatible with determinism -- and one of its striking features is a certain asymmetry: it requires the ability to do otherwise for responsibility when actions are praiseworthy, but not when they are blameworthy. In defending and elaborating the view, Nelkin questions long-held assumptions such as those concerning the relation between fairness and blame and the nature of so-called reactive attitudes such as resentment and forgiveness. Her argument not only fits with a metaphysical picture of causation -- agent-causation -- often assumed to be available only to incompatibilist accounts, but receives positive support from the intuitively appealing Ought Implies Can Principle, and establishes a new interpretation of freedom and moral responsibility that dovetails with a compelling account of our inescapable commitments as rational agents.

The aim of this inquiry is to investigate Heidegger's ontology of technology. We will show that this ontology is aporetic. In Heidegger's key technical essays, ?The question concerning technology? and its earlier versions ?Enframing? and ?The danger?, enframing is described as the ontological basis of modern life. But the account of enframing is ambiguous. Sometimes it is described as totally binding and at other times it appears to allow for exceptions. This oscillation between, what we will call total enframing and (...) partial enframing, is underscored in the work of two influential scholars of Heidegger's later thought, Hubert Dreyfus and Iain Thomson. We will show that like Heidegger, Dreyfus and Thomson unwittingly perpetuate this dilemma that ultimately covers up the aporetic structure of enframing. (shrink)

With the continual development of artificial intelligence and smart computing in recent years, quantitative approaches have become increasingly popular as an efficient modeling tool as they do not necessitate complicated mathematical models. Many nations have taken steps, such as transitioning to online schooling, to decrease the harm caused by coronaviruses. Inspired by the demand for technology in early education, the present research uses a radial basis function neural network modeling technique to predict preschool instructors’ technology usage in classes based on (...) recognized determinant characteristics of technology acceptance. In this regard, this study utilized the RBFNN approach to predict preschool teachers’ technology acceptance behavior, based on the theory of planned behavior, which states that behavioral achievement, in our case the actual technology use in class, depends on motivation, intention and ability, and behavioral control. Thus, this research design is based on an adapted version of the technology acceptance model with eight dimensions: D1. Perceived usefulness, D2. Perceived ease of use, D3. Perceived enjoyment, D4. Intention to use, D5. Actual use, D6. Compatibility, D7. Attitude, and D8. Self-efficacy. According to the TAM, actual usage is significantly predicted by the other seven dimensions used in this research. Instead of using the classical multiple linear regression statistical processing of data, we opted for a NN based on the RBF approach to predict the actual usage behavior. This study included 182 preschool teachers who were randomly chosen from a project-based national preschool teacher training program and who responded to our online questionnaire. After designing the RBF function with the actual usage as an output variable and the other seven dimensions as input variables, in the model summary, we obtained in the training sample a sum of squares error of 37.5 and a percent of incorrect predictions of 43.3%. In the testing sample, we obtained a sum of squares error of 14.88 and a percent of incorrect predictions of 37%. Thus, we can conclude that 63% of the classified data are correctly assigned to the models’ dependent variable, i.e., actual technology use, which is a significant rate of correct predictions in the testing sample. This high significant percentage of correct classification represents an important result, mainly because this is the first study to apply RBFNN’s prediction on psychological data, opening up a new interdisciplinary field of research.

Dana S. Belu combines Heidegger's phenomenology of technology with feminist phenomenology in order to make sense of the increased technicization of women's reproductive bodies during conception, pregnancy, and birth.

Individual differences in phonological processing abilities have often been attributed to perceptual factors, rather than to factors relating to learning and memory. Here, we consider the contribution of individual differences in declarative and procedural memory to phonological processing performance in adulthood. We examined the phonological processing, declarative memory, and procedural memory abilities of 79 native English-speaking young adults with typical language and reading abilities. Declarative memory was assessed with a recognition memory task of real and made-up objects. Procedural memory was (...) assessed with a serial reaction time task. For both tasks, learning was assessed shortly after encoding, and again after a 12-h, overnight delay. We regressed phonological processing ability with memory performance on both days. We found that declarative memory, but not procedural memory, was highly predictive of phonological processing abilities. Specifically, declarative memory scores obtained shortly after learning were associated with non-word repetition performance, whereas declarative memory scores obtained after the overnight delay were associated with phonological awareness. Procedural memory was not associated with either of the phonological processing measures. We discuss these findings in the context of adult participants with mature phonological systems. We examine possible implications for the relationship between declarative memory and phonological processing in adulthood. (shrink)

Many philosophers hold that it is conceptually impossible to form a belief simply by willing it. Noting the failure of previous attempts to locate the presumed incoherence, Dion Scott-Kakures offers a version of the general line that voluntary believing is conceptually impossible because it could not qualify as a basic intentional action. This discussion analyzes his central argument, explaining how it turns on the assumption that a prospective voluntary believer must regard the desired belief as not justified, given her other (...) beliefs. It then shows that this assumption is false and also that some initially plausible suggestions for weakening the assumption fail to secure Scott-Kakures’s conclusion. (shrink)

In this anthology of new and classic articles, fifteen noted feminist philosophers explore contemporary ethical issues that uniquely affect the lives of women. These issues in applied ethics include autonomy, responsibility, sexual harassment, women in the military, new technologies for reproduction, surrogate motherhood, pornography, abortion, nonfeminist women and others. Whether generated by old social standards or intensified by recent technology, these dilemmas all pose persistent, 'nagging,' questions that cry out for answers.

I describe an ethic for business administration based on the social tradition of the Catholic Church. I find that much current thinking about business falters for its conceit of truth. Abstractions such as the shareholder-value model contain truth - namely, that business is an economic enterprise to manage for the wealth of its owners. But, as in all abstractions, this truth comes at the expense of falsehood -namely, that persons are assets to deploy on behalf of owners. This last is (...) "wrong" in both senses of the word - it is factually wrong in that persons are far more than business assets, they are supernatural beings, children of God; and it is morally wrong in that it is an injustice to treat them as the former when they are the latter. I draw upon the social tradition of the Catholic Church to recognize that the business of business is not business, but is instead the human person. Following Church teachings, I describe a person-centered ethic of business based upon eight social principles that both correct and enlarge the shareholder-centered ethic of much current business thinking. I discuss implications of this person-centered ethic for business administration. (shrink)

In The Minority Body, Elizabeth Barnes rejects prevailing social constructionist accounts of disability for two reasons. First, because they understand disability in terms of oppressive social responses to bodily impairment, they cannot make sense of disability pride. Second, they maintain a problematic distinction between impairment and disability. In response to these challenges, this paper defends a version of the social model of disability, which we call the Social Exclusion Model. On our account, to be disabled is to be in a (...) bodily or psychological state that is represented as an impairment in the prevailing ideology of one’s society, and to be excluded from valuable activities on the basis of this representation. While this model refers to a distinction between disability and impairment, it makes no presuppositions about which bodies function ‘normally’ and which do not. It is the ideology of impairment rather than impairment itself that does any work to determine whether a person is disabled. We argue that this model answers some of the important objections that Barnes raises against prevailing social constructionist accounts of disability, and that it’s focus on the oppressive social positioning of disabled people gives it explanatory power that Barnes’s own account lacks.

In everyday life, we assume that there are degrees of blameworthiness and praiseworthiness. Yet the debate about the nature of moral responsibility often focuses on the “yes or no” question of whether indeterminism is required for moral responsibility, while questions about what accounts for more or less blameworthiness or praiseworthiness are underexplored. In this paper, I defend the idea that degrees of blameworthiness and praiseworthiness can depend in part on degrees of difficulty and degrees of sacrifice required for performing the (...) action in question. Then I turn to the question of how existing accounts of the nature of moral responsibility might be seen to accommodate these facts. In each case of prominent compatibilist and incompatibilist accounts that I consider, I argue that supplementation with added dimensions is required in order to account for facts about degrees of blameworthiness and praiseworthiness. For example, I argue that the reasons-responsiveness view of Fischer and Ravizza requires supplementation that takes us beyond even fine-grained measures of degrees of reasons-responsiveness in order to capture facts about degrees of difficulty to extend the reasons-responsiveness view by appealing to such measures). I conclude by showing that once we recognize the need for these additional parameters, we will be in a position to explain away at least some of the appeal of incompatibilist accounts of moral responsibility.

The importance of a healthy mentoring relationship, and how to go about achieving one, has been explored in several disciplines, including psychology. However, little of this work has focused specifically on unique ethical issues that may arise while mentoring undergraduate students. The authors provide a definition of mentoring in the context of undergraduate education that takes into account undergraduates' status as emerging adults. We delineate both similarities and differences between mentoring undergraduate students and graduate students. Ethical issues that may arise (...) while mentoring undergraduates, especially around themes of vocation, autonomy and influence, boundaries, power, the priority of the protg's needs, the mentor's motives, and accessibility, are spotlighted. We argue that although there is considerable overlap between mentoring graduate students and mentoring undergraduates, there are issues and concerns unique to working with undergraduates that require explication so that they can be appropriately addressed to the benefit of both protg and mentor.

We investigate the notion of a semi-retraction between two first-order structures (in typically different signatures) that was introduced by the second author as a link between the Ramsey property and generalized indiscernible sequences. We look at semi-retractions through a new lens establishing transfers of the Ramsey property and finite Ramsey degrees under quite general conditions that are optimal as demonstrated by counterexamples. Finally, we compare semi-retractions to the category theoretic notion of a pre-adjunction.

Our seamless perception of the world depends very much on the slow time scales used by conscious perception. Time scales longer than one second are needed to assemble conscious experience. At time scales shorter than one second, this seamlessness quickly deteriorates. Numerous experiments reveal the fragmentary nature of the visual information used to construct visual experience. Models of how the brain manages these fragments use the construct of a routine, which is a task-specific fragment of a sensory-motor program. This paper (...) provides an overview of some of the experiments that test these models. Its aim is to show how the structures that they elucidate constrain the understanding of conscious perception.

Further, if he knew his ticket would lose, then, given that his ticket is no different in its chances (...) of winning from any other ticket, it seems that by parity of reasoning he should also know that every other ticket would lose. But of course he doesn’t know that; in fact, he knows that not every ticket will lose. (shrink)

Theodor Adorno once wrote an essay to "defend Bach against his devotees." In this book Dana Villa does the same for Hannah Arendt, whose sweeping reconceptualization of the nature and value of political action, he argues, has been covered over and domesticated by admirers who had hoped to enlist her in their less radical philosophical or political projects. Against the prevailing "Aristotelian" interpretation of her work, Villa explores Arendt's modernity, and indeed her postmodernity, through the Heideggerian and Nietzschean theme (...) of a break with tradition at the closure of metaphysics.Villa's book, however, is much more than a mere correction of misinterpretations of a major thinker's work. Rather, he makes a persuasive case for Arendt as the postmodern or postmetaphysical political theorist, the first political theorist to think through the nature of political action after Nietzsche's exposition of the death of God. After giving an account of Arendt's theory of action and Heidegger's influence on it, Villa shows how Arendt did justice to the Heideggerian and Nietzschean criticism of the metaphysical tradition while avoiding the political conclusions they drew from their critiques. The result is a wide-ranging discussion not only of Arendt and Heidegger, but of Aristotle, Kant, Nietzsche, Habermas, and the entire question of politics after metaphysics. (shrink)

While ideals of racial purity may be out of fashion, other sorts of purity ideals are increasingly popular in the United States today. The theme of purity is noticeable everywhere, but it is especially prominent in our contemporary fixation on health and hygiene. This may seem totally unrelated to issues of racism and classism, but in fact, the purveyors of purity draw upon the same themes of physical and moral purity that have helped produce white identity and dominance in the (...) US. Historically, this is where the purity rhetoric gets its power. To invoke purity ideals in the US is to mobilize this genealogy of racialized associations. Today's zealous preoccupation with hygiene is part of our living heritage in a racist culture.Just as ideas of race and racial purity were debunked by biologists long before the public would begin to question them, ideals of extreme hygienic purity linger with us, even flourish, despite scientific evidence of their futility and harm. Why are we still so enamored with purity? Because, to some extent, our very self-conceptions are at stake. Other scholars have described how our process of self individuation is based upon exclusion. The unique contribution of a genealogical approach to this issue is that, instead of merely locating the problem in ideologies held by others, it can evoke self-recognition and self-transformation. We will tend to assume the problem lies elsewhere until we learn to recognize ourselves in practices that reproduce cultural ideals. As inheritors of this racist culture, we are all lovers of purity, and we are all responsible for rethinking this value. (shrink)

It is argued that once biological systems reach a certain level of complexity, mechanistic explanations provide an inadequate account of many relevant phenomena. In this article, I evaluate such claims with respect to a representative programme in systems biological research: the study of regulatory networks within single-celled organisms. I argue that these networks are amenable to mechanistic philosophy without need to appeal to some alternate form of explanation. In particular, I claim that we can understand the mathematical modelling techniques of (...) systems biologists as part of a broader practice of constructing and evaluating mechanism schemas. This argument is elaborated by considering the case of bacterial chemotactic networks, where some research has been interpreted as explaining phenomena by means of abstract design principles.

This volume explores the themes of vanishing matter, matter and the laws of nature, the qualities of matter, and the diversity of the debates about matter in the early modern period. Chapters are unified by a number of interlocking themes which together enable some of the broader contours of the philosophy of matter to be charted in new ways. Part I concerns Cartesian Matter; Part II covers Matter, Mechanism and Medicine; Part III covers Matter and the Laws of Motion; and (...) Part IV covers Leibniz and Hume. Bringing together some of the world’s leading scholars of early modern philosophy, as well as some exciting new researchers, _Vanishing Matter and the Laws of Motion _stakes out new territory that all serious scholars of early modern philosophy and science will want to traverse.

This article uses Acker's theory of gendered organizations to frame an analysis of the ways in which policies and practices in a men's and a women's prison reflect and reproduce gendered inequalities. The article offers a working definition of one of Acker's key theoretical concepts, the notion of “gendered organizational logic.” Then, using interview data collected from correctional officers in a men's and a women's prison, the article examines the ways in which officer training and assignments, although designed to be (...) nominally generic, assume a male worker and disproportionately benefit male officers working in men's institutions. These findings imply that the perspective could more usefully be conceived as a theory of “masculinized” organizations. (shrink)

In The Second Sex, Simone de Beauvoir diagnoses “woman” as the “lost sex,” torn between her individual autonomy and her “feminine destiny.” Becoming a “real woman” in patriarchal societies demands that women lose their authentic, autonomous selves to become the “inessential Other” for Man. To better understand this diagnosis and how women might refind themselves, I rehabilitate the influence of Søren Kierkegaard and his concept of repetition as what must be lost to be found again in Beauvoir’s account of freedom (...) and, specifically, the liberation of women. Beauvoir offers a dual account of repetition, that of mundane repetition and sacrificial repetition, bringing them to bear both on her diagnosis of women’s oppression and her theorization of our liberation. Sacrificial repetition becomes a temporality for freedom—one must be able to repeat or retake their autonomy continuously toward an open future. For this to happen concretely, Beauvoir insists that we must sacrifice the (racist, classist) patriarchal ideals of the “real woman” and “real man” as we retake our autonomy and reconfigure the meaning of sex difference anew.
