Aquinas claims that ‘He Who Is’ is the most proper of the names we have for God. But this attempt to ‘describe’ God with a philosophical concept like ‘being’ can seem dangerously close to creating a false conception based on our limited understanding – an idol. A dominant criticism of Aquinas’ use of this term is that any attempt to use ‘being’ to describe God will inevitably make him merely some object in our ontology alongside other beings, unacceptably mitigating God's (...) radical transcendence and otherness. I will argue that Aquinas has a very creative response to this charge: ‘being’ stands in a unique relationship as the only concept that can ensure we do not draw God under some particular creaturely limit and thus use divine names to create an ‘idol’. In other words, ‘being’ is a special paradigm concept/term which ensures that we preserve humility in our attempts to name God. -/- . (shrink)

John Courtney Murray is openly acknowledged as one of the greatest public political thinkers that American Catholicism has produced. His work significantly influenced the Catholic Church's public understanding of the role of religion in a pluralistic society through his contributions to the Declaration on Religious Liberty (Dignitatis Humanae) of the Second Vatican Council. He was even acclaimed in the secular world, appearing on the cover of Time on December 12, 1960. His legacy in the area of church–state relations, however, ran (...) into serious difficulties shortly after his death. Many have alleged that the cause of this nonreception lay in a new religious pluralism in the United States or in a lack of consensus on basic moral or philosophical issues. I will argue, by contrast, that one overlooked, but highly influential, reason for this lack of reception lies in Murray's position on the relationship between nature and grace. The triumph of a competing view in the post-conciliar Catholic Church and wider academy, both in theology and in philosophy, undermined the possibility of Murray's vision finding traction within either realm.

W. Matthews Grant has argued that it is possible to reconcile a strong theory of God’s causal sovereignty with libertarian freedom by denying that God causes the acts of free creatures by means of some factor intrinsic to Himself. Grant argues that the accounts on which God causes those actions of His creatures in virtue of His decrees cannot be libertarian. I will argue that two classical theories of grace, despite holding that God causes creaturely acts in virtue of a (...) divine decree or intention, remain libertarian in just the same sense Grant’s account is. I controversially propose that this is true even of Banezian theories of grace, on which God causes free actions directly. Instead, I suggest that we can characterize what it is for a theory to be theological determinist according to a distinction proposed by Eleonore Stump. (shrink)

This article undertakes a republican analysis of power in the workplace and labour market in order to determine whether workers are dominated by employers. Civic republicans usually take domination to be subjection to an arbitrary power to interfere with choice. But when faced with labour disputes over what choices it is normal for workers to make for themselves, these accounts of domination struggle to determine whether employers possess the power to interfere. I propose an alternative capabilitarian conception of domination as (...) the arbitrary power to determine access to capabilities necessary for relationships of equality between citizens. This approach allows us to diagnose domination in the workplace and the labour market but does not capture unfreedom arising from the wider socio-structural position of workers. Thus, I supplement this capabilitarian account of the domination of workers with a structural account of dominating power, which reveals a richer set of conditions under which employers dominate workers.

The republican ideal of non-domination identifies the capacity for arbitrary interference as a fundamental threat to liberty that can generate fearful uncertainty and servility in those dominated. I argue that republican accounts of domination can provide a powerful analysis of the nature of legal and institutional power that is encountered by people with mental disorders or cognitive disabilities. In doing so, I demonstrate that non-domination is an ideal which is pertinent, distinctive, and desirable in thinking through psychological disability. Finally, I (...) evaluate republican strategies for contesting domination, focusing on the limits of contestatory democracy, and proposing a participatory alternative which better addresses problems of political agency in the mentally disordered and cognitively disabled.

Socialist republicans advocate public ownership and control of the means of production in order to achieve the republican goal of a society without endemic domination. While civic republicanism is often attacked for its conservatism, the relatively neglected radical history of the tradition shows how a republican form of socialism provides powerful conceptual resources to critique capitalism for leaving workers and citizens dominated. This analysis supports a programme of public ownership and economic democracy intended to reduce domination in the workplace and (...) wider society. I defend this socialist republicanism from both the Marxist objection that it overlooks the impersonal nature of domination under capitalism and the left-liberal objections that property-owning democracy or worker codetermination are sufficient to suppress dominating relationships. The resulting position identifies the need for more ambitious institutional grounds for republican liberty than is often supposed, while offering us a distinctive emancipatory justification for socialism.

This article argues that political injustices can arise from the distribution and character of our sexual desires and that we can be held responsible for correcting these injustices. It draws on a conception of structural injustice to diagnose unjust patterns of sexual attraction, which are taken to arise when socio-structural processes shaping the formation of sexual desire compound systemic domination and capacity-deprivation for the occupants of a social position. Individualistic and structural solutions to the problem of unjust patterns of sexual (...) attraction are assessed in the context of racialised sexual aversion, racial fetishism, and the desexualisation of people with disabilities. While both forms of intervention can help in principle, some of the advantages of structural approaches are laid out. A schema for assigning political responsibilities for addressing this injustice is proposed, with some limits identified to the kinds of state and social responses that are justified. Finally, the status of the merely aesthetically unappealing is considered, with a relational egalitarian approach concluding that they are subject to structurally unjust patterns of sexual desire only when exposed to oppression or second-class citizenship as a result.

Economic liberty is best understood in opposition to economic domination. This article develops a radical republican conception of such domination. In particular, I argue that radical republicanism provides a more satisfactory account of individual economic freedom than the market-friendly liberties of working, transacting, holding, and using championed by Nickel and Tomasi. So too, it avoids the pitfalls of other conceptions of economic liberty which emphasize real freedom, alternatives to immiserating work, or unalienated labor. The resulting theory holds that economic domination (...) occurs when someone’s access to civic capabilities is contingent on the arbitrary economic power of others. Socialist institutions—suitably configured—can deliver on this individual economic freedom, allowing the dominating power of proprietors, shareholders, landlords, and managers to be kept in check, and providing an unconditional minimum that allows individual citizens to be less beholden to others in meeting many of their most fundamental civic needs. Thus, I conclude that socialism can be championed as a politics of individual economic liberty. (shrink)

The World Trade Organisation, and the international trade regime within which it operates, is regularly evaluated in terms of distributive outcomes or opportunities. A less-established concern is the extent to which the institutional structure of the trade regime enables agents to exert control over the economic forces to which they’re subject. This oversight is surprising, as trade negotiations amongst states have profound impacts upon what options remain open to those states and their citizens in regulating their economies. This article contributes (...) to filling this lacuna in the literature. Following on from recent neo-republican work on global and international justice, it argues that a major problem with the WTO is that it fails to effectively mitigate the domination of some states by others within its negotiations. Such domination prevails despite the employment of negative consensus as a decision-making procedure. (shrink)

I remain unsatisfied by a lack of philosophical clarity among Báñezian authors on the nature of freedom. In a recent paper, I therefore posed a problem for Báñezianism that resembles what is called the “grounding problem” for Molinism: where do the truths about alternative possibilities come from? And I illustrated the problem in the context of the account of grace given by one famous defender of the view, Fr. Réginald Garrigou-Lagrange, whose work in turn was recently promoted by Taylor Patrick (...) O’Neill. O’Neill responds in this present journal issue to that paper, arguing that I failed to be attentive to distinctions drawn by Garrigou-Lagrange which would resolve the dilemma. However, I fear that O’Neill’s presentation of both the dilemma and his own resolution is conceptually confused. I will try to illustrate that O’Neill’s own responses are at many points either a concession to a certain fork of the dilemma that I posed in the original paper, or change the subject and fail to address my concerns except superficially. However, since at many points O’Neill implies that I reject Báñezianism, despite my explicit qualification in the paper that I do not, I will end by proposing what would constitute a sufficient response to the dilemma.

ABSTRACT: It is a familiar story that Kant’s defence of our synthetic a priori cognition in the Critique of Pure Reason suffered sharp criticism throughout the extended philosophical revolutions that established analytic philosophy, the pragmatist tradition, and the phenomenological tradition as dominant philosophical movements in the first half of the twentieth century. One of the most important positive adaptations of Kant’s outlook, however, was the combined analytic and pragmatist conceptions of the a priori that were developed by the American philosophers (...) C. I. Lewis (1883–1964) and Wilfrid Sellars (1912–1989), most notably in Lewis’s 1929 classic, Mind and the World Order, followed by Sellars’ critical reworking of Lewis’s outlook in ‘Is There a Synthetic A Priori?’ (1953) and other mid-century articles. Both Lewis and Sellars defended central aspects of Kant’s analysis of our a priori knowledge of mind-independent physical objects and necessary causal connections. But both also radically transformed Kant’s view by defending the idea that there are alternative a priori conceptual frameworks that are subject to an ongoing process of reassessment and replacement on overall pragmatic and explanatory grounds. Furthermore, while Sellars’ answer to his question, ‘Is There a Synthetic A Priori?’ thus represented a partial endorsement of Lewis’s pragmatic relativization of the a priori, I argue that Sellars’ account of meaning diverged from Lewis in ways that constituted a significant improvement upon the previous ‘analytic’ defenses of the a priori, not only in Lewis but in general. This arguably has implications for wider disputes concerning the nature and possibility of a priori knowledge in non-formal domains. (shrink)

I develop a socialist republican conception of economic liberty and show how it can be used to understand the domination of workers. It holds that both paid and unpaid workers can be deprived of economic freedom when they are exposed to an arbitrary power to undermine their access to the economic capabilities needed for civic equality. Measures intended to reduce domination are recommended, including public ownership of productive property, workplace democracy, and robust unconditional basic income and services. Finally, I discuss (...) the implications of this approach for platform capitalism, digital surveillance, the rise of automation, and post-work politics. (shrink)

This article challenges the individualism and neutrality of modern moral conscience. It looks to the history of the concept to excavate an older tradition that takes conscience to be social and morally responsive, while arguing that dominant contemporary justifications of conscience in terms of integrity are inadequate without reintroducing these social and moral traits. This prompts a rethinking of the nature and value of conscience: first, by demonstrating that a morally-responsive conscience is neither a contradiction in terms nor a political (...) absurdity; second, by suggesting how a morally-responsive conscience can be informed by the social world without being a mere proxy for social power or moribund tradition.

This article develops a civic republican approach to medical ethics. It outlines civic republican concerns about the domination that arises from subjection to an arbitrary power of interference, while suggesting republican remedies to such domination in healthcare. These include proposals for greater review, challenge and pre-authorisation of medical power. It extends this analysis by providing a civic republican account of assistive arbitrary power, showing how it can create similar problems within both formal and informal relationships of care, and offering strategies (...) for tackling it. Two important objections to civic republican medical ethics—that it overvalues independence and political participation in healthcare—are also considered and rebutted. (shrink)

Harrison Frye claims that socialist republicanism may be unable to reduce domination due to efficiency costs and accountability deficits imposed by public ownership. I argue that the empirical and theoretical grounds for expecting such a decline in economic efficiency are weak. Moreover, the egalitarian distributive effects of public ownership are likely to be more important for insulating people from domination. So too, workers, consumers, and citizens are not well-protected from domination by the accountability of managers to profit-seeking shareholders. I conclude (...) that the investor-owned firm will do far more to exacerbate dominating power than to constrain it. (shrink)

I reconstruct the civic republican foundations of Eugene Debs’s socialist critique of capitalism, demonstrating how he uses a neo-roman conception of freedom to condemn waged labour. Debs is also shown to build upon this neo-roman liberty in his socialist republican objections to the plutocratic capture of the law and threats of violence faced by the labour movement. This Debsian socialist republicanism can be seen to rest on an ambitious understanding of the demands of citizen sovereignty and civic solidarity. While Debs (...) shares some of the commitments of earlier American labour republican critics of capitalism, he departs from them in his thoroughgoing commitment to common democratic ownership of productive property. His socialist republicanism remains valuable today for its ability to illuminate features of plutocratic control, judicial autocracy, and the regime of property best suited to suppressing economic domination. I conclude that Debs not only deserves a prominent place in an emerging radical republican canon but presents a distinctive contrast with many of his Marxist contemporaries and offers a compelling challenge to recent liberal, plebeian, and socialist forms of republicanism.

This selective overview of the history of American Philosophy in the Twentieth Century begins with certain enduring themes that were developed by the two main founders of classical American pragmatism, Charles Sanders Peirce (1839--1914) and William James. Against the background of the pervasive influence of Kantian and Hegelian idealism in America in the decades surrounding the turn of the century, pragmatism and related philosophical outlooks emphasizing naturalism and realism were dominant during the first three decades of the century. Beginning in (...) the 1930s and 1940s, however, the middle third of the century witnessed the rising influence in America of what would become known as “‘analytic philosophy’,” with its primary roots in Europe: in the Cambridge philosophical analysis of Moore, Russell, and Wittgenstein; logical empiricism and positivism on the continent; and linguistic analysis and ordinary- language philosophy at Oxford. This overview stresses the persistence of pragmatist themes throughout much of the century, while emphasizing the mid-century transformations that resulted from developments primarily in analytic philosophy. These combined influences resulted at the turn of the millennium in the flourishing, among other developments, of distinctively analytic styles of pragmatism and naturalism. (shrink)

This chapter develops a civic republican approach to disability justice. It begins by articulating a republican account of liberty as nondomination before showing how such domination can shape the relationships of people with disabilities. This leads to a consideration of whether disability justice can be defined in terms of maximizing or sufficient nondomination. Instead, the chapter provides a civic framework within which republican disability justice can be understood, encompassing both the absence of oppressive relationships and the presence of capabilities of (...) special egalitarian concern. It also considers some specific normative implications of a republican account of disability justice—doubting the suitability of contestatory democracy but pointing toward the merits of self-education and universal basic income. Finally, the objection that this republican approach to disability justice unreasonably denigrates dependence is rebutted. (shrink)

Philosophy in Africa has for more than a decade now been dominated by the discussion of one compound question, namely, is there an African philosophy, and if there is, what is it? The first part of the question has generally been unhesitatingly answered in the affirmative. Dispute has been primarily over the second part of the question as various specimens of African philosophy presented do not seem to pass muster. Those of us who refuse to accept certain specimens as philosophy (...) have generally been rather illogically said also to deny an affirmative answer to the first part of the question.

This article draws upon the civic republican tradition to offer new conceptual resources for the normative assessment of mental capacity law. The republican conception of liberty as non-domination is used to identify ways in which such laws generate arbitrary power that can underpin relationships of servility and insecurity. It also shows how non-domination provides a basis for critiquing legal tests of decision-making that rely upon ‘diagnostic’ rather than ‘functional’ criteria. In response, two main civic republican strategies are recommended for securing (...) freedom in the context of the legal regulation of psychological disability: self-authorisation techniques and participatory shaping of power. The result is a series of proposals for the reform of decisional capacity law, including a transition towards purely functional assessment of decisional capacity, surer legal footing for advanced care planning, and greater control over the design and administration of decision-making capacity laws by those with psychological disabilities.

In a world characterised by intense global poverty, do active corporate efforts to help the global poor constitute discretionary acts of charity, to be praised but not to be thought of as mandatory? Or, conversely, are such efforts a matter of binding moral duty? The traditional position among business ethicists – and still, perhaps, the dominant one – is that there is no such duty, except perhaps in exceptional circumstances such as rescue cases. In recent years, however, several authors have (...) made the case that corporations have quite wide-ranging positive duties to the global poor. This entry outlines the contours of the various arguments given in favour of the latter position, before highlighting two theoretical challenges which arise if we are to embrace this position – first, the issue of determining what sorts of actions count as adequately fulfilling positive duties to the global poor, and, second, the question of what limits there are, if any, to the demandingness of corporations’ positive duties.

This paper attempts to locate modern Zen and psychoanalysis in terms of contemporary philosophy of mind, particularly in view of dominant theories of cognitivism that see the mind as informational and material, with meaning being mere information in disguise. Psychoanalysis and modern Zen hold to the contrary view that the mind is “semantic,” not “syntactic,” and that the meanings we have in our heads are not reducible to the physical informational processes from which they have emerged. Meaning, as non-reducible, is (...) infinite and uncaused. However, the structure of meaning entails a split between a knower and what is known. This split creates problems in the mind which can be confronted through more, not less, engagement with the meanings in our minds, until we are self-aware and, perhaps, self-identical, with the mechanisms of consciousness that produce the meanings in our head. Such self-awareness is seen as being self-liberating rather than self-reducing. (shrink)

In Beyond Art (2014), Dominic Lopes proposed a new theory of art, the buck passing theory. Rather than attempting to define art in terms of exhibited or genetic featured shared by all artworks, Lopes passes the buck to theories of individual arts. He proposes that we seek theories of music, painting, poetry, and other arts. Once we have these theories, we know everything there is to know about the theory of art. This essay presents two challenges to the theory. (...) First, this essay argues that Lopes is wrong in supposing that theories of arts were developed to deal with the ‘hard cases’ – developments such as Duchamp’s readymades and conceptual art. This is a problem since Lopes holds that the buck passing theory’s capacity to deal with the hard cases is one of its virtues. Second, this essay argues that the buck passing theory has no account of which activities are arts and no account of what makes some activity an art. (shrink)

When it comes to fulfilling our basic duties to distant others, we in the affluent world face a motivation gap; we consistently fall short of bearing even moderate costs for the sake of helping others secure basic minimums to which they are entitled. One response to the motivation gap is to cultivate in affluent populations a greater concern for distant others; cultivating such concern is the goal of ‘sentimental cosmopolitanism’. Two approaches to sentimental cosmopolitanism currently dominate the literature, a compassion-based (...) and a complicity-based approach, respectively. In this paper, I argue for the promise of reciprocity as an alternative motivator of cosmopolitan concern. I further argue that a sense of obligation to distant others, grounded in our participation in an ongoing system of reciprocal exchange, can be cultivated within a thus-far overlooked sphere of cosmopolitan sensitization, namely the market. I make the case for the market as an appropriate site for cosmopolitan sensitization, and further argue that multinational corporations are, for several reasons, well-positioned to bear the political responsibility of sensitizing affluent populations to the significance of their participation in a cooperative economic scheme shared with distant others. This paper, then, makes a novel contribution to debates on cosmopolitan sentiment, as well as to the emerging literature on corporations’ political responsibilities.

This paper does three interrelated things. First, it argues that the universalism that forms the target of criticism and attack by decolonial theorists from the Global South is a debased form of universalism, what might be termed “ethnocentric universalism.” Second, equipped with a conceptual grip on ethnocentric universalism, it shows that the picture on which ethnocentric universalism confers some innocuous epistemic privilege to members of dominant groups is not quite accurate—ethnocentric universalism is incompatible with the epistemic flourishing of members of (...) dominant groups. And third, based on that claim, and the additional consideration that ethnocentric universalism equally undermines the epistemic flourishing of members of historically marginalized groups, it proposes an emancipatory framework for engaging with it.

Gottfried Wilhelm Leibniz presents the idea of monads, as non-communicative, self-actuating system of beings that are windowless, closed, eternal, deterministic and individualistic. For him, the whole universe and its constituents are monads and that includes humans. In fact, any ‘body’, such as the ‘body’ of an animal or man has, according to Leibniz, one dominant monad which controls the others within it. This dominant monad, he often refers to as the soul. If Leibniz’s conception of monads is accepted, it merely (...) establishes human subjectivity, idiosyncrasies, biases, prejudices and individual points of view as the norm. How then do we ensure inter-subjectivity and the kind of social interaction requisite for the achievement of social order, since Leibniz’s system forecloses the possibility of interaction and communication among monads? In this essay, we argue that just as Leibniz’s monads synchronize only through the Supreme Monad (Monas Monadum), humans as social monads should also interact through a matrix of ideals like truth, honesty, sincerity, integrity, altruism, impartiality, compassion and trust. Since social order is actualised only within the context of linked social structures, relations and values, these utopian ideals would form the fulcrum through which humans relate and the very foundation that would anchor a viable social order. Our aim here is to establish a relationship between Leibniz’s metaphysics and the physical domains of life by showing that metaphysical constructs can impinge on human social relations and wellbeing. The study employed the qualitative method of research through critical analysis of texts, library and archival materials. (shrink)

The evolution of Intelligent Tutoring System (ITS) is the result of the amount of research in the field of education and artificial intelligence in recent years. English is the third most common languages in the world and also is the internationally dominant in the telecommunications, science and trade, aviation, entertainment, radio and diplomatic language as most of the areas of work now taught in English. Therefore, the demand for learning English has increased. In this paper, we describe the design of (...) an Intelligent Tutoring System for teaching English language grammar to help students learn English grammar easily and smoothly. The system provides all topics of English grammar and generates a series of questions automatically for each topic for the students to solve.

The intelligent tutoring system was given to a group of students of all age groups to try it and to see the impact of the system on students. The results showed a good satisfaction of the students toward the system. (shrink)

Research assessment and grant funding are vital to higher education. However, the reliance on quantitative metrics in these processes has raised concerns about their validity and potential negative consequences. This study aims to investigate the game of numbers in research assessment and grant funding, focusing on the perspectives of experienced researchers from around the globe. Accidental sampling elicited responses from more than 15 experienced researchers across different academic disciplines, institutions, and countries. The data were collected from the popular “Reviewer 2 (...) Must be Stopped!” Facebook platform, which includes more than 135,000 members across the globe. Two posts were made, allowing participants to share their experiences, perspectives, and concerns related to metrics and numbers in research assessment and grant funding. The results from the thematic analysis revealed diverse perspectives among experienced researchers. Some participants expressed concerns about the dominance of quantitative metrics, highlighting the limitations and potential biases associated with their use. Others acknowledged the value of certain indicators in showcasing research impact. Moreover, the impact of metrics on grant funding awards was also documented. The study highlights the necessity for a more balanced and context-aware approach to research assessment and grant funding, incorporating qualitative measures and acknowledging the diverse nature of research impact.

The aim of my paper is to review the discussion concerning various difficulties which surround the definition of depression and the methods of diagnosing and treating the disease against the background of the now dominant reductionist paradigm in psychiatry, as well as to answer the question whether a new approach to psychiatric disorders proposed by philosophers of psychiatry working within the phenomenologically inspired embodied and enactive paradigm indeed offers a solution to these difficulties. I present the issues specific to the (...) subject of depression in light of the more general problems related to biological psychiatry that have recently caused much debate. In the second part of the paper, I consider enactive, phenomenological and embodied theories of depression and the possibilities of new methods of treatment. My goal is to assess whether these theories indeed add anything important to the conceptions that are already present in psychiatry. I conclude that even if the embodied philosophy of psychiatry does not solve many of the problems faced by modern psychiatry, it can, nevertheless, provide a useful theoretical basis for future changes.

This study aims to deepen the philosophical aspects of the relationship between the work of Pierre Hadot and Michel Foucault, with regard to the concepts of "Spiritual Exercises" and "Self-Care". We intend to analyze how Pierre Hadot interpreted the appropriation that Michel de Foucault made of his text "spiritual exercises", when presenting the notion about the definition of "Care of the self". We elucidate the main divergences and convergences present between the philosophical reflections of these two authors, which are of (...) great relevance for the understanding of current phenomena. The methodology adopted was exploratory theoretical-bibliographic research, halfway betweena comment and an essay. Our studies point to the theme of 'the self' as the central point of the research, with “Self-Care” as the bias capable of leading us to knowledge and, in this way, taking us to the direction of existence through the rationality ofthe “Exercises” Spiritual ”. Our two authors, in their discussions about “taking care of oneself”, evoke in part the thinking of the Greeks, who are the source of the definition of this principle. Therefore, the term “epimeleia heauton” will guide us, that is, to undertake in the face of the world of life, in the practice of thorough and permanent criticism in the face of one's own conduct. In other words, by means of these spiritual exercises, thus being able to contemplate oneself rationally on a path towards "oneself" and through "oneself". Furthermore, all of this implies a constant effort on the will and desire, in order to architect authentic autonomy on a daily basis. We do not intend to exhaust the whole subject, however, the relationship to be developed will bring us closer to dominance over ourselves and make us reflect on the state of "having oneself in the hands.".

[What It’s Like, or What It’s About? The Place of Consciousness in the Material World] Summary: The book is both a survey of the contemporary debate and a defense of a distinctive position. Most philosophers nowadays assume that the focus of the philosophy of consciousness, its shared explanandum, is a certain property of experience variously called “phenomenal character,” “qualitative character,” “qualia” or “phenomenology,” understood in terms of what it is like to undergo the experience in question. Consciousness as defined in (...) terms of its phenomenal aspect is often called “phenomenal consciousness.” The major issue that occupies most thinkers is whether this phenomenal character happens to be a physical property, or whether it is rather sui generis. Those who believe the former are materialists; those who conclude the latter are dualists. As the currently dominant metaphysic is materialism – also sometimes called physicalism – the challenge appears to be to slot phenomenal properties among the physical properties that ultimately make up the world. David Chalmers argued powerfully that we can go very far in situating many mental properties in the physical world – namely, the properties that can be understood in functional terms – but that phenomenal properties resist such a treatment. Chalmers calls this “the hard problem” of consciousness. But there are also some quite powerful positive arguments for dualism. The two most influential ones are the modal argument, also offered by Chalmers, and the knowledge argument invented by Frank Jackson. Chalmers invites us to conceive of creatures that are exactly like human beings – physically, functionally, behaviorally – only bereft of phenomenal consciousness. If such creatures are conceivable, says Chalmers, they are metaphysically possible. And if they are metaphysically possible, materialism is false. Jackson, for his part, suggests we imagine Mary who has spent her entire life inside a black-and-white room and has seen the world through a black-and-white TV screen. But she also happens to know everything there is to know about the physics of color. And yet, Jackson suggests that once Mary is finally released from her room and sees a lawn outside, she learns something new: that this is what it is like to experience green color. The current work on consciousness is by and large characterized by attempts to answer these two dualistic arguments. I try to make sense of the positions within the domain of philosophy of consciousness by means of two major distinctions that mutually intersect. First, there is a distinction between dualism and materialism. An apparent third alternative currently on offer, the so-called Russellian monism, is unstable, collapsing into either dualism (panpsychism) or materialism (Russellian physicalism). Materialism comes in two main flavors: either the a posteriori physicalism, which detects an epistemic gap between phenomenal and physical truths, hence denying that the former could be derived from the latter; or the a priori physicalism, which does not acknowledge any such obstacle. The second major distinction is between phenomenism and representationalism. It’s true that Ned Block, who introduced this contrast, meant to distinguish between two kinds of materialism. But I believe that the distinction actually intersects the one between materialism and dualism. We thus arrive at a table with six slots, representing six main positions in the philosophy of consciousness: (1) dualist phenomenism (Chalmers, the early Jackson, and Tyler Burge); (2) dualist representationalism (René Descartes); (3) aposteriori materialist phenomenism (Block); (4) a posteriori materialist representationalism (Michael Tye, Fred Dretske, David Rosenthal); (5) a priori materialist phenomenism (David Lewis); and (6) a priori materialist representationalism (Daniel Dennett, Derk Pereboom). However, this scheme is in fact somewhat misleading. It is true that Dennett is usually classified as an apriori materialist (or, more precisely an apriori materialist representationalist), but I believe that needs to be corrected. In order to understand why, I first analyze varieties of materialist representationalism in detail, in particular various construals of phenomenal character in terms of representation, or intentionality, which includes a discussion of the identity of its content (the issue of externalism). By contrast, Dennett rejects the concept of phenomenal character. Consciousness has no intrinsic, publicly inaccessible properties. On that ground, Dennett builds an empirical, fully functionalist theory of consciousness, which he also tries to integrate within a general Darwinian framework. From that point of view, one can contrast Dennettian and representationalist views on the issue of animal consciousness. In addition to his rejection of phenomenal character, Dennett also abstains from the regular metaphysical departure point of regular materialism. He does not so much ask how an enigmatic property of consciousness fits an antecedently characterized world, but rather how far we can investigate all aspects of the world, including consciousness, using the scientific method. He is thus a methodological naturalist, rather than a metaphysical materialist. While this approach removes obstacles to the science of consciousness, it does not solve what might be called “the hardest problem” – of intentionality, not phenomenal consciousness. The hardest problem consists in the fact that our intentional discourse involves conflicting commitments that prevent a coherent metaphysic of representational states. However, it does not follow that we should give up on this discourse as a theoretical means of reduction as well as a practical tool of explanation.

This article aims to develop the outline of a possible philosophy of the digital, as a proper philosophy with its own domain, questions, methods and own theories. The article starts by describing the crisis of liniar thinking undersood, following Vilém Flusser, as as a crisis of historical-causal thinking. Then the digital thinking is described as a new way of thinking which aims to become the dominant way of scientific explanation of our times, by replacing historical-causal explanations with numerical models. The (...) proper domain of a philosophy of the digital is then defined as the digital-life form. The article ends by showing an example of a specific problem for the philosophy of the digital, namley the automatisation of human life. (shrink)

In this chapter I will present, in a general way, Millikan's biosemantic theory of the phenomenon of intentionality. For this purpose, the text will take the following path. First, I will present the problem of intentionality and an overview of the dominant theories of intentional content during the twentieth century and part of the twenty-first century. Then, I will present a general version of Millikan's biosemantic theory, appearing in 1984, which will allow us to see what the relevance and originality (...) of his proposal consists in. Finally, in keeping with one of the central purposes of Las filósofas que nos formaron, I will share a brief interview that Millikan very kindly agreed to give for this publication, in which she tells us some non-theoretical aspects of her history as a philosopher.

Human beings define their identity primarily by the way they present, design and style their bodies. In doing so, individuals make statements about their affiliation to a social context. Globalisation implies a change of identity among the members of less industrialised cultures, as they are exposed to effects of cultural dominance. For the individual, this exposure can be the stronger, the more autonomous his or her culture of origin used to be before the confrontation. There is a bias of cultural (...) elements that are being transferred, so that the industrialised culture has a strong impact on other cultures. Global consent with regard to behaviour patterns, especially to bodily self-presentation and the related cognitive styles, leads to the obliteration of traditional knowledge, which is interwoven with the behaviour upon which identity had been defined previously. The cultural elements transferred are being used for the construction of globally standardised personal identities, whereat elements concerning the visual design of the human body are of major relevance for defining the self. The loss of variegated identities in favour of belonging to the global society brings about a number of problems, which can be demonstrated in functional models. These models, in turn, may support the planning of interventional strategies and rescue work. In this article, the role of the body within the destabilising effects of cultural change are analysed, and chances for intervention are discussed. (shrink)

Aristotle presents the concept of Eudaimonia in his work “Ethica Nicomachea”, which can be translated as “living well” and “acting well”. However, it is not clear whether this Supreme Good is something dominant or inclusive in relation to the virtues investigated by him throughout the 10 books of the work. In order to debate this doctrinal classification, commentators have been arguing in favor of both aspects, especially since the beginning of the 20th century. This essay aims to argue in favor (...) of the dominant theory based on a reading of the original work translated into English, refuting pro-inclusive arguments presented by J. Ackrill, in his article “Aristotle on Eudaimonia.”. (shrink)

The paper focuses on the “spillover thesis” which constitutes a pillar of much of contemporary participatory democratic theory; specifically, we assess the claim that workplace democratization leads to a higher degree of political participation amongst labourers. The paper analyses the thesis as formulated by Carole Pateman, including its later revisions triggered by ambiguous results of empirical studies aiming to (dis)prove it. The spillover thesis is then confronted with important methodological and theoretical critiques, the upshot being that in order to be (...) able to arrive at determinate conclusions, more carefully designed empirical studies are needed. Normatively speaking, however, blame can always be laid on the wider environment of market economy and/or representative democracy, to the effect that the spillover thesis is both difficult to disprove and radically subversive. Given the recent dominance of deliberative democratic theory which incorporates a strong participatory element, we finally discuss whether a recent innovation – namely, the concept of deliberative systems – could be fruitfully employed as a flexible umbrella-type framework for the spillover thesis and the participatory ideals related to it.

This paper aims at examining the issue of the role of supreme being theology in non-Abrahamic traditions. According to the dominant view in contemporary philosophy of religion, the philo-sophical project of inferring divine properties from the concept of God as a maximally perfect being, usually called supreme being theology, is an exclusivity of the Abrahamic traditions. In attempting to question this view, I investigate the developments of two key-concepts of Vedāntatradition –the concepts of Brahman (literally, the greatest) and Bhagavān (literally, (...) the possessor of all excellences) –in thethought of three famous vedantins: Śaṅkara, Rāmānuja and Jīva.

This dissertation critically examines the writings of Max Stirner, especially his masterpiece The Ego and Its Own, as a discourse of resistance against modern forms of domination and, in particular, against the modern political State. I begin by examining Stirner's inversion of the Hegelian concept of the State, from the “actualization of freedom”to an instance of domination. The State appears, to Stirner as to Hegel, as the guardian of order and cohesion in modern societies. While both recognize the genesis of (...) sovereign power as violent, Hegel sustains that, with the progress of civilization, force is eradicated from the public order and private interests and common interest are reconciled. Stirner, on the contrary, insists that force is the other face of right, as the hidden pillar of the norm, which only reveals itself in moments of crisis. Stirner’s focus on the extreme case, largely anticipated and devalued by Hegel as unilateral and equivocal, seems to be anchored on the conviction that conflict is ineradicable, that between my own will and the (political, social) representation of that will there is always a gap, which cannot be filled by any collective arrangement. From this follows that, if conflict is scarcely manifest in modern societies, it is not because it was truly solved, but because it is effectively masked, due to the dissymmetry of power and the internalization of authority. The “unique one” appears, in this environment of great suspicion, as the one who cannot be represented, who surpasses every representation, threatening the authority of every representative. Accordingly, the “unique one” reclaims his own power, without allowing the satisfaction of his will to be mediated by obedience to collective institutions, affirming himself instead as sovereign over himself. Stirner suggests that the self-affirmation of the “unique one” inevitably leads to confrontation with the external powers that organize his existence. Stirner, nonetheless, chooses to think this confrontation in terms of a “revolt”, of a reflexive and individual act by which the individual emerges from the situation in which he finds himself, rather than as a “revolution”, a political or social act directed towards the systemic transformation of the status quo. Even if we admit the validity of the Stirnerian critique of the legitimizing discourses of modernity, the problem remains if this critique can be sustained on the “unique one”, “a thoughtless word”, an openly self-contradictory and self-destructive name, subject or principle (?). The possibility of founding a discourse of resistance on the egoism of Max Stirner seems to depend upon the answer that we choose to give to two intimately connected questions: what remains after the destructive vortex of the “unique one” that may sustain the resistance against a state that Max Stirner deems oppressive? Can this resistance be realized in the revolt of a unique one without the recognition of another one with whom to build the conditions of freedom? (shrink)

How does economics understand the human being? In this article, I present the current dominant conception of the human being in neoclassical theory, which is usually labelled as 'homo oeconomicus' (economic man). I describe the traits of this anthropology, and present the historical context in which it emerged. Then I make its critical evaluation. This is followed by a discussion of two recent alternative conceptions of the human being, which try to go beyond the individualist 'homo economicus' paradigm. I highlight (...) the recent contributions of John B. Davis and Luigino Bruni. Finally I reflect on some elements of Christian anthropology which can contribute to enrich the conception of the person in economics. (shrink)

The ontological determination of the movement in its quality of way of Being incessantly moves the critic affirmed to denial it through come to be which affirms new critics, unity of continuities and discontinuities with the previous critic. Therefore, it is important to unveil the material determinations in which are rooted the conception of Being dissociated from Non-being consolidated in insurmountable distinction between Being and Entity in its quality of expression of ideas in an inverted reality, falsely apprehended. Ideally reproduced (...) reality that, nevertheless, allows alternatives corresponding to the realization of aims targeted to satisfy historically determined necessities. The confrontations in the production and reproduction of purposes to guide social relations cross-dress debility of determined and impotent movement to impose determinations to the full virtuosity of immobility that moves the transitory. The difference between Being e Entity conforms in a formal logic deprived from/of contradiction to affirm the development of knowledge in what, in truth, hindered and limit it to remain, reducing the movement to stationary, to what moves to what moves without moving, to what isolate the knowledge of reality, to what detaches idea and material, to what conserves and incarcerates and not to what transform and set free. The treatment conceived as a movement from radical critic brings together the ontological primacy to underpin the root of the constitution of social existence to establish the ontological determinations of the existence to consciousness is stated in Marx – being reaffirmed in Lukács – by affirming that categories are forms of Being, determinations from/of existence. The category of totality, as a result of it, constitute expression of form of Being from reality in movement and synthesis from multiples and mutual determinations of negated diversities in an unitarity which affirm them. Therefore, the dialectical reflexive movement refuses as an ineliminable condition to the movement which affirms to mould identity with unitarity between identity and non-identity or don’t conceive relation of identity with dialectic, with the existence of reality to express a contradiction and incessant transmutation between Being and Non-being. The totality by transmuting itself while remain totality albeit not identical to the previous moment embraces a category to synthesize the unity of diversity. This diversity moved and moving from/by unity contemplates the relation of identity ratio (nowadays totality) between the identity (continuity with the preceding totality) and the non-identity (discontinuity with the preceding totality). To ignore the identity of identity with a non-identity conforms the impotence of category to constitute an expression of existence for not affording the contradiction immanent to the existence of reality moving from transport incessant of Being to come to be which puts itself from Non-being to Being. In short, concomitantly the being is transposed to Non-being to a Being come to be transpose from Non-being to a Being whilst ontological determination is constituted and constitutive of movement. The realization of critic conditioned the self-critic that ontologically determines the denial of self-preservation because it constitutes roots in social conditions that limit the intended transformation through critic. The critique of science as an ideological and material condition of reproduction and realization of capital is not effective with the auto-conservation of Geography for conforming the necessity of conservation of science to be rooted in the conception of distinction idealized by superiority that would affirm the permanence and nullity of transcending the limitations to denial the inhumanity of alienation concomitantly affirm the conditions to recognition of necessities and possibilities oriented to an emancipatory purposes. The progressive compressing of expenditure of time on production and productivity of results in various fields of scientific knowledge – which do not realize strictly in the extent of knowledge or it would be equivalent to affirm the fallacy of isolation and to deny the material and historical determinations that constitutes the quality of form of Being -, expressed in the quality of objective necessity and possibility concomitantly to fragment the form and content of the orientation of aims for investigation and for apprehension of reality. The convergence of the movements above-mentioned conforms the constitution of consensus positivity of complexifying of knowledge, delimitating the conceiving of reality and the supposed objective determinations a priori that constraint the conscious apprehension of necessities and of purposes that manifestate in the immediacy by the quality of developing individual and humankind potentialities of social being. Therefore, the conception of suprahistorical and insuppressible ontological determination depriving from social intentionalities in naturalize the impute of greater speed and complexity with lesser time and size of fragmented reality to be known, strengthening the conditions of inversion of reality. Reversed reality deforms the conscious apprehension of corresponding reduce the humanity of individual and gender social sphere of Being for alienating the necessities and goals of theory and practice, consciously aimed to the development of conditions for impoverishment humanity cross-dress in fallaciously things provided by humanity. Things that would had identity with men humanization obfuscating the unifying the developing of thing in the developing of men in the quality of thing, to conceive the most primary theoretical and practical necessity for the purpose of development of thing as an irrevocable necessity from human activity. The confrontation in the sphere of ideas constitutes itself while conceiving the real and, in this direction, the domination of necessities and purposes of material (re)production of society requires the domination of the categories of space and time as forms of Being of substance in motion. The detachment between Being and Entity conceives the indetermination of the dominant conception of reality that determines the conditions for the reproduction of life and the come to be of individuals and humankind.

We are quickly passing through the historical moment when people work in front of a single computer, dominated by a small CRT and focused on tasks involving only local information. Networked computers are becoming ubiquitous and are playing increasingly significant roles in our lives and in the basic infrastructure of science, business, and social interaction. For human-computer interaction o advance in the new millennium we need to better understand the emerging dynamic of interaction in which the focus task is no (...) longer confined to the desktop but reaches into a complex networked world of information and computer-mediated interactions. We think the theory of distributed cognition has a special role to play in understanding interactions between people and technologies, for its focus has always been on whole environments: what we really do in them and how we coordinate our activity in them. Distributed cognition provides a radical reorientation of how to think about designing and supporting human-computer interaction. As a theory it is specifically tailored to understanding interactions among people and technologies. In this article we propose distributed cognition as a new foundation for human-computer interaction, sketch an integrated research framework, and use selections from our earlier work to suggest how this framework can provide new opportunities in the design of digital work materials.

PUERPÉRIO EM BOVINOS -/- INTRODUÇÃO -/- O puerpério é definido como o período entre o parto e a apresentação do primeiro estro fértil. Dois processos ocorrem durante o puerpério: a involução uterina e o início da atividade ovariana pós-parto. Em vacas leiteiras, os cuidados médicos pós-parto são essenciais nos programas de manejo, uma vez que as patologias uterinas são diagnosticadas e tratadas nesse período para que a vaca esteja em ótimas condições para ser inseminada, uma vez terminado o período de (...) espera voluntário. -/- 4.1 Involução uterina -/- O útero após o parto sofre modificações macroscópicas e microscópicas, até atingir as características de um útero não gestante, o que leva de 30 a 45 dias. O peso e o tamanho pós-parto diminuem rapidamente como consequência da atrofia das fibras musculares; por necrose das carúnculas e por eliminação de líquidos. Ao mesmo tempo em que o útero diminui de tamanho, o endométrio passa por um processo regenerativo para poder hospedar uma nova gestação. -/- A involução é promovida pelas contrações uterinas, que facilitam a eliminação de fluidos e dejetos e reduzem o tamanho do útero. As contrações são causadas pela secreção contínua de PGF2α, de origem uterina, e pela ocitocina secretada durante a amamentação. A PGF2α é secretada durante as primeiras 3 semanas pós-parto e seu envolvimento é considerado necessário para que a involução uterina ocorra normalmente. -/- Durante a involução uterina, as secreções conhecidas como lóquios, que são formadas por restos de membranas, carúnculas, fluidos fetais e sangue, são derramadas pela vagina. Essas secreções variam da cor vermelha ao marrom, têm consistência viscosa e são inodoras. A maioria dos lóquios é descartada durante os primeiros 15 dias após o parto e, em seguida, praticamente desaparece, exceto em casos de involução uterina anormal, quando o útero continua a derramar fluidos de consistência, cor e odor diferentes (figura 1). -/- Figura 1: O útero após o parto sofre alterações macroscópicas e microscópicas, até atingir as características de um útero não grávido, o que leva de 30 a 45 dias. -/- Antes do parto, o útero é estéril, pois é protegido da contaminação bacteriana pelo colo do útero ou cérvix. Durante e após o parto, essa barreira física desaparece e o útero é invadido por bactérias que se encontram no meio ambiente, pele e fezes, ou que são introduzidas durante a assistência ao parto. Além disso, a capacidade funcional dos fagócitos uterinos é baixa após o parto, o que contribui para o estabelecimento de infecções. Cerca de 95% das vacas desenvolvem infecções uterinas durante a involução, e uma alta porcentagem de vacas as eliminam por meio de mecanismos naturais. -/- Os mecanismos de defesa uterinos são constituídos pelas barreiras anatômicas (vagina, vulva e cérvix); fatores fisiológicos (produção de muco na vagina e cérvix); fagocitose promovida por neutrófilos, que migram da circulação geral para o útero; pela produção de substâncias inespecíficas, que inibem o crescimento bacteriano e favorecem a eliminação de microrganismos. A capacidade de eliminar bactérias do útero é determinada pelos hormônios ovarianos (progesterona e estrogênios); durante o diestro, a progesterona reduz a migração de neutrófilos, suprime o sistema imunocompetente, fecha o colo do útero e causa atonia uterina, resultando em aumento da suscetibilidade à infecção. Ao contrário, durante a fase folicular do ciclo estral (proestro e estro), o estradiol promove a migração de neutrófilos, abre a cérvix e aumenta o tônus uterino, o que facilita a eliminação de agentes infecciosos. Além disso, a atividade dos neutrófilos é afetada pelas deficiências antioxidantes e pela profundidade do balanço energético negativo. -/- 4.2 Anormalidades do puerpério -/- Após o parto, ocorrem algumas patologias que retardam a involução uterina e, consequentemente, afetam o intervalo entre o parto e o primeiro serviço. -/- 4.2.1 Retenção da placenta -/- A placenta é eliminada dentro de 12 horas após o parto; a retenção da placenta por mais de 24 horas é considerada uma patologia. A retenção placentária (RP) é uma alteração frequente do puerpério, que deve ser considerada como um sinal clínico de várias condições que podem ter origem infecciosa (aborto), metabólica (hipocalcemia, cetose, síndrome do vaca gorda), deficiências nutricionais (selênio e vitamina E) e erros de manejo (demasiada intervenção no parto). -/- A incidência de RP varia de 5 a 15% e depende, em grande parte, do estado de saúde e do manejo do rebanho. A RP é o principal fator de risco para infecções uterinas (metrite puerperal, metrite, endometrite e endometrite subclínica); também causa atraso no período entre o parto e a concepção e está associada à redução do percentual de concepção no primeiro serviço. -/- Em termos econômicos, determinou-se que a RP causa perdas significativas principalmente devido aos custos de serviços médicos, aumento da taxa de eliminação e diminuição da fecundidade. Além disso, vacas com retenção placentária produzem 355 kg a menos de leite durante os primeiros 60 dias do que vacas que não apresentam esta patologia (figuras 2 e 3). -/- 4.2.2 Patogenia -/- A placenta está ligada ao endométrio pelas vilosidades coriônicas, que estão ligadas às carúnculas (junção carúncula-cotilédone). A união entre essas estruturas é favorecida por um fluido adesivo formado por colágeno e outras proteínas. Antes e durante o trabalho de parto, observa-se um aumento da atividade das enzimas proteolíticas (colagenase, talvez a mais importante), que são responsáveis por separar o cotilédone da carúncula. Posteriormente, a placenta é removida mecanicamente por contrações uterinas após o parto do feto. -/- A etiologia e patogênese da retenção placentária não são conhecidas. Uma explicação proposta é que isso se deve a uma falha dos mecanismos proteolíticos responsáveis pela separação do cotilédone da carúncula. Foi observado que a atividade da colagenase no cotilédone é maior em vacas que não retêm placenta do que naquelas que a retêm. Propõe-se que alguns fatores de risco para retenção placentária possam estar atuando na redução da atividade da colagenase. Por outro lado, as condições inflamatórias na junção carúncula-cotilédone de origem infecciosa também impedem a separação da placenta. -/- Figura 3: Vaca com retenção placentária. -/- Figura 2: Vaca com retenção placentária. Em rebanhos comerciais, 5 a 15% das vacas retêm a placenta. -/- 4.2.3 Tratamento -/- Existem vários tratamentos, como a remoção manual da placenta em combinação com a aplicação local de antibióticos (infusões intrauterinas) e a administração de produtos hormonais (ocitócicos e PGF2α). A eficácia desses tratamentos é discutível. -/- A remoção manual da placenta é o tratamento mais popular; entretanto, não é a melhor, pois causa danos ao endométrio, que variam de leve sangramento a hematomas, mesmo quando não há evidências externas. Além disso, a remoção manual diminui a capacidade fagocítica dos leucócitos uterinos, resultando em metrite mais grave, maior atraso na involução uterina e baixo desempenho reprodutivo. -/- Outro tratamento consiste em cortar a placenta ao nível da vulva. Posteriormente, quando a placenta se separa das carúnculas, devido ao processo de decomposição do tecido, uma leve tração da vulva é suficiente para retirá-la, sem consequências. Essas vacas devem ser observadas quanto à febre e imediatamente integradas ao programa de check-up pós-parto, pois certamente desenvolverão metrite ou endometrite. A administração de antibióticos, tanto nos casos de retirada manual como naqueles em que a placenta é cortada, depende do estado geral da vaca. Deve-se sempre ter em mente que a RP é o principal fator de risco para metrite, portanto as vacas devem ser observadas para detectar prontamente aquelas que apresentam febre. Os antibióticos devem ser considerados para inibir a putrefação das membranas fetais, o que pode atrasar sua expulsão. No caso de opção pela administração de antibióticos, deve-se optar pela via parenteral em vez da intrauterina, pois esta causa irritação do endométrio, que está associada à baixa fertilidade (figura 4). -/- Outros tratamentos são baseados na administração de hormônios que estimulam a mobilidade uterina (ocitocina, estrogênios e PGF2α); entretanto, não há evidências clínicas que demonstrem sua eficácia; além disso, a causa menos frequente de RP é a incapacidade mecânica do útero de expelir a placenta. -/- 4.2.4 Prevenção -/- As estratégias de prevenção dessa patologia devem ter como objetivo reduzir a influência dos fatores de risco para RP. Assim, a incidência de abortos deve ser reduzida por meio de programas eficazes de vacinação e biossegurança; deve-se evitar períodos de seca muito longos para que as vacas não cheguem obesas ao parto; intervir o mínimo possível nos partos, e se atendido, deve ser feito com medidas de higiene rígidas; oferecer sais minerais de boa qualidade e administrar antioxidantes antes do parto (vitamina E, selênio e betacarotenos; tabela 1). -/- Figura 4: A placenta não deve ser removida inserindo a mão na vagina. É aconselhável aguardar a autólise (48 horas) e removê-la por leve tração. -/- Tabela 1: Incidência de retenção na membrana fetal (RMF), metrite hemorrágica (HM), metrite purulenta (PM) e puerpério anormal (PA) em vacas leiteiras tratadas com selênio e vitamina E nos dias 60, 21 antes do parto e 30, 90 pós-parto (grupo pré-pós-parto) e 21 dias pré-parto (grupo pré-parto) e testemunhas. -/- Laterais diferentes na mesma coluna indicam diferença estatística (P < 0,05). Adaptado de RUIZ et al., 2008. -/- 4.3 Infecções uterinas -/- Cerca de 95% das vacas desenvolvem infecção uterina durante os primeiros dias pós-parto; no entanto, a maioria elimina infecções por meio de seus mecanismos de defesa e apenas 30 a 50% delas desenvolvem metrite ou endometrite nas primeiras três semanas. As bactérias mais frequentes encontradas em processos inflamatórios no útero são: Arcanobacterium pyogenes (antes Actinomyces pyogenes), Fusobacterium necrophorum e Escherichia coli. Essas três bactérias agem sinergicamente. -/- 4.3.1 Metrite puerperal -/- A metrite puerperal é comum em vacas com retenção placentária. Essa patologia é observada nas três primeiras semanas pós-parto e é caracterizada pela presença de secreções abundantes na luz uterina que são vermelhas ou marrons, aquosas, fétidas e com involução retardada. As vacas afetadas mostram sinais de doença sistêmica (toxemia e febre > 39,5 °C) e diminuição da produção de leite (figura 5). -/- Figura 5: Vaca com metrite puerperal; vacas afetadas apresentam sinais de doença sistêmica. -/- 4.3.2 Metrite clínica -/- Metrite é o processo inflamatório que envolve as diferentes camadas do útero (mucosa, muscular e serosa). Esta condição se apresenta nos primeiros 21 dias pós-parto e é caracterizada por atraso na involução uterina e secreção purulenta, e não há sinais de doença sistêmica (figura 6). -/- 4.3.3 Endometrite clínica -/- Endometrite se refere à inflamação do revestimento uterino; clinicamente, caracteriza-se por retardo na involução uterina e eliminação de exsudato purulento ou mucopurulento. Pode surgir nos primeiros 21 dias pós-parto ou mais, sem apresentar qualquer afetação no estado geral. -/- Figura 6: Vaca com exsudato mucopurulento. Na prática, é difícil estabelecer um diagnóstico diferencial entre endometrite e metrite. Uma vaca com essa secreção pode ser tratada com cefalosporinas intrauterinas ou, se ela já estiver em ciclo, a administração de PGF2a é eficaz. -/- 4.3.4 Endometrite subclínica -/- Apresenta-se entre 21 e 40 dias pós-parto, não apresenta sinais externos e só é diagnosticada pela citologia uterina. Essa condição afeta entre 20 e 30% das vacas. Os fatores de risco identificados são retenção placentária e metrite. -/- 4.4 Diagnóstico -/- O diagnóstico é baseado na avaliação uterina por palpação retal, na qual são verificados o grau de involução e as características das secreções. Além disso, é necessária uma avaliação clínica geral, uma vez que vacas com metrite nos primeiros 10 dias pós-parto desenvolvem febre. Outra forma de estabelecer o diagnóstico é avaliando as secreções uterinas sem palpação retal. Pode ser feito introduzindo a mão por via vaginal, após a limpeza da região; embora este método possa parecer arriscado, a experiência em campo indica que é um método seguro e rápido. Outra possibilidade é por meio da vaginoscopia, esse método permite a avaliação da cérvix e das secreções uterinas. Existe um instrumento (Metricheck) que é inserido pela vagina e possui uma campânula atraumática na extremidade que permite a coleta das secreções uterinas (figuras 7 e 8). -/- 4.5 Impacto das infecções uterinas na reprodução e produção -/- As infecções uterinas (metrite e endometrite) prolongam o período do parto até a concepção; diminuem a porcentagem de concepção no primeiro serviço; a porcentagem de resíduos aumenta; a taxa de vacas inseminadas diminui e a produção diminui (300 kg a menos que vacas não afetadas). Além disso, eles afetam o período do parto à primeira ovulação; em vacas com puerpério anormal, os folículos dominantes são menores em diâmetro e produzem menos estradiol do que vacas saudáveis. Também uma proporção menor dos folículos da primeira onda ovula em comparação com as vacas com puerpério anormal. -/- A endometrite subclínica diminui a taxa de concepção no primeiro serviço e aumenta os dias abertos. Além disso, a metrite ou endometrite pode afetar os ovidutos e causar inchaço, obstrução e aderências (esse processo é mais frequente em vacas que recebem injeções de estrogênio). -/- Figura 8: Outra forma de diagnosticar infecções uterinas é por meio da introdução de um instrumento que possui em sua extremidade uma campânula atraumática que permite a coleta de secreções uterinas (Metricheck). -/- Figura 7: O diagnóstico de infecções uterinas pode ser estabelecido com a introdução da mão por via vaginal, após limpeza da região. -/- 4.6 Tratamentos -/- Para evitar o efeito negativo das infecções uterinas na eficiência reprodutiva, é necessário um diagnóstico e tratamento oportunos. Existem diversos tratamentos para a metrite ou endometrite, como o uso de antibióticos sistêmicos ou intrauterinos, infusões intrauterinas de antissépticos e a administração de hormônios. -/- 4.6.1 Antibióticos -/- Os tratamentos com antibióticos intrauterinos são usados há muitos anos e são uma opção, desde que alguns aspectos sejam considerados: que o útero é um ambiente anaeróbio; que há a presença de exsudatos e tecidos em decomposição e a existência de uma grande diversidade de bactérias, algumas das quais até produzem enzimas que inativam alguns antibióticos. -/- Como o útero é um ambiente anaeróbio, os antibióticos do grupo dos aminoglicosídeos não são ativos, pois precisam de oxigênio. Por outro lado, o acúmulo de exsudato purulento e restos de tecido no útero inibe a atividade das sulfonamidas. Os nitrofuranos são eficazes contra A pyogenes, somente quando doses extremamente altas são usadas; as doses usuais nunca atingem a concentração inibitória mínima no endométrio; além disso, não são ativos na presença de sangue ou exsudato purulento, são irritantes e estão associados a problemas de fertilidade. -/- A penicilina intrauterina ou parenteral é eficaz na cura de infecções entre os dias 25 e 30 após o parto; ou seja, quando for observada uma diminuição na diversidade de espécies bacterianas (menor probabilidade de que algumas bactérias produzam penicilinase) e predomina A pyogenes, que é sensível a este antibiótico. As formulações intrauterinas de cefalosporinas (cefapirina benzatina) são eficazes em vacas com endometrite entre os dias 15-20 pós-parto e não é necessário retirar o leite do mercado. -/- A tetraciclina é o antibiótico mais utilizado devido ao seu amplo espectro e por manter sua atividade nas condições do útero pós-parto; porém, a probabilidade de resistência bacteriana é alta devido ao seu uso contínuo por muitos anos, também causa danos ao endométrio e reduz a fertilidade (figura 9). -/- Em testes de campo, a administração de uma única infusão intrauterina de cefapirina benzatina, em vacas com endometrite entre os dias 15 a 20 pós-parto, produz uma maior taxa de recuperação e não afeta a fertilidade, em comparação com aquelas que foram tratadas com infusões de oxitetraciclina. -/- O problema mais importante na terapia com antibióticos é estabelecer um critério de quais animais realmente precisam. Nos casos de metrite puerperal não há dúvida, essas vacas precisam de tratamento com antibióticos por via sistêmica e intrauterina. Porém, em casos de metrite e endometrite a decisão é difícil, pois muitas vacas se curam sem nenhum tratamento. Na prática, antes que os antibióticos sejam administrados às vacas, deve-se considerar alguns dos fatores: características das secreções uterinas, dias após o parto, início da atividade ovariana, presença de febre e condição corporal. -/- Figura 9: As infusões de oxitetraciclina causam irritação do endométrio e diminuem a fertilidade. -/- 4.6.2 Tratamento com infusões de substâncias antissépticas -/- Tratamentos baseados na administração intrauterina de substâncias antissépticas também são usados. O tratamento mais frequente consiste na infusão de soluções de iodo; no entanto, os resultados com esta terapia não são positivos e estão associados a uma diminuição subsequente da fertilidade. Deve-se ter cautela no uso de antissépticos intrauterinos, pois todos causam irritação, afetam os mecanismos de defesa do útero e, em alguns casos, chegam a causar necrose do endométrio. -/- 4.6.3 Tratamentos hormonais -/- Na prática, a administração de estrogênio é comum em casos de metrite, principalmente quando o útero retém muito líquido. Sabe-se que os estrógenos em condições fisiológicas favorecem a contratilidade uterina e auxiliam na eliminação de infecções, porém, em doses farmacológicas o efeito é negativo. A administração de estrogênios pode contribuir para infecções que ascendem aos ovidutos e causam salpingite, aderências ovarianas e infertilidade. -/- A PGF2α desempenha um papel importante no parto e durante a involução uterina. Em vacas com puerpério normal, a duração dos níveis elevados de PGF2α está negativamente correlacionada com o tempo de involução uterina; portanto, quanto mais tempo duram os níveis elevados de PGF2α, menor é o tempo de involução uterina. Além disso, a administração de PGF2α a cada 12 horas, dos dias 3 a 10 pós-parto, encurta o período de involução uterina. Ao contrário, em vacas com puerpério anormal, foi observada uma correlação positiva entre as concentrações de PGF2α e o tempo de involução uterina; portanto, vacas com retenção placentária ou endometrite apresentam níveis mais elevados de PGF2α. -/- Algumas evidências envolvem a PGF2α como parte do mecanismo de eliminação da placenta; ou seja, foi observado que as vacas que normalmente eliminam a placenta apresentaram maiores concentrações de PGF2α na placenta, em comparação com as vacas com retenção placentária. Foi proposto que a falha do processo que leva à separação do cotilédone da carúncula está associada a uma alteração no metabolismo da prostaglandina, resultando em uma diminuição na PGF2α e um aumento na PGE2. Por outro lado, a inibição da síntese de PGF2α após o parto, por meio da injeção de ácido acetilsalicílico (aspirina), causa retenção da placenta. Esse conhecimento motivou estudos nos quais o tratamento com PGF2α após o parto foi avaliado para prevenir a retenção placentária ou reduzir o tempo de involução em vacas com retenção placentária ou metrite. Em alguns estudos, uma única injeção de PGF2α foi administrada nas primeiras horas após o parto com resultados conflitantes. Em outros estudos, a injeção de PGF2α entre os dias 20 a 30 pós-parto foi avaliada e não foi observado um efeito favorável na involução uterina. Porém, a injeção sistemática de PGF2α, a cada 14 dias a partir do 25º dia pós-parto, aumenta a proporção de vacas inseminadas, o que aumenta a taxa de prenhez. A PGF2α causa contrações uterinas e favorece a eliminação de secreções; entretanto, um efeito favorável da PGF2α na involução uterina, sem envolver um corpo lúteo, é questionável. -/- Na prática, um programa é usado com base na administração sistemática de PGF2α a todas as vacas a cada 14 dias, do 25º ao 30º dia pós-parto. Esse tratamento é baseado no encurtamento das fases lúteas, o que favorece a eliminação das infecções. Deve-se observar que cerca de 30% das vacas desenvolvem corpos lúteos longevos (21 a 50 dias) nos primeiros ciclos pós-parto, nessas condições a injeção de PGF2α, a cada 14 dias, encurta o ciclo estral e diminui o risco de persistência de infecções uterinas. -/- 4.7 Piometra -/- Esta patologia se desenvolve em vacas que ovulam nos primeiros 20 dias pós-parto e, concomitantemente, sofrem de infecção uterina. Nessas condições, a progesterona promove a proliferação bacteriana e fecha o colo do útero, causando acúmulo de exsudato purulento no útero. As alterações causadas no endométrio alteram a secreção de PGF2α, resultando na persistência do corpo lúteo e anestro. Vacas com piometra respondem muito bem ao tratamento com PGF2α; uma segunda injeção desse hormônio, 14 dias depois, encurta o período de recuperação (figura 10). -/- Figura 10: A piometra é caracterizada pelo acúmulo de exsudato purulento no útero, colo uterino fechado e presença de corpo lúteo. O diagnóstico é feito por palpação retal e tratado com PGF2α. -/- 4.8 Vaginite em fêmeas gestantes -/- A vaginite em fêmeas grávidas ocorre com baixa frequência; porém, quando há um caso, causa alarme porque é confundido com um aborto. Nesses casos, o veterinário deve fazer um exame retal para determinar se o produto está vivo e se a cérvix está aberta. O diagnóstico é concluído com o exame vaginal com vaginoscópio ou diretamente à mão com luva limpa. -/- No caso de um aborto, o produto geralmente está morto e a cérvix está aberta; nestes casos, o produto deve ser extraído. Ao contrário, se a cérvix estiver fechada e o feto estiver vivo, o prognóstico é favorável e o problema diminui com o tratamento com antibióticos sistêmicos. -/- RESUMO -/- < >O útero após o parto pesa 13 kg e no dia 21 pós-parto, 1 kg. A regeneração do epitélio uterino leva 25 dias. A regeneração das camadas profundas do endométrio leva 42 a 56 dias. 95% das vacas desenvolvem alguma infecção uterina. 30 a 50% das vacas desenvolvem metrite nas primeiras duas semanas após o parto. 15 a 20% persistem como endometrite clínica > 3 semanas após o parto. 18 a 20% têm metrite com efeitos sistêmicos. 20 a 30% das vacas têm endometrite subclínica. 5 a 15% das vacas retêm a placenta. 355 kg de leite são perdidos em vacas com retenção placentária. Em vacas que sofrem de puerpério anormal, a proporção de vacas prenhes é reduzida em 10 por cento no 90º dia pós-parto. No Reino Unido, 192 euros são gastos por cada vaca que tem um puerpério anormal. REFERÊNCIAS BIBLIOGRÁFICAS -/- ANDREWS, Anthony H. et al. (Ed.). Bovine medicine: diseases and husbandry of cattle.

Systems of logico-probabilistic (LP) reasoning characterize inference from conditional assertions interpreted as expressing high conditional probabilities. In the present article, we investigate four prominent LP systems (namely, systems O, P, Z, and QC) by means of computer simulations. The results reported here extend our previous work in this area, and evaluate the four systems in terms of the expected utility of the dispositions to act that derive from the conclusions that the systems license. In addition to conforming to the dominant (...) paradigm for assessing the rationality of actions and decisions, our present evaluation complements our previous work, since our previous evaluation may have been too severe in its assessment of inferences to false and uninformative conclusions. In the end, our new results provide additional support for the conclusion that (of the four systems considered) inference by system Z offers the best balance of error avoidance and inferential power. Our new results also suggest that improved performance could be achieved by a modest strengthening of system Z. (shrink)

Pronouns often convey information about a person’s social identity (e.g., gender). Consequently, pronouns have become a focal point in academic and public debates about whether pronouns should be changed to be more inclusive, such as for people whose identities do not fit current pronoun conventions (e.g., gender non-binary individuals). Here, we make an empirical contribution to these debates by investigating which social identities lay speakers think that pronouns should encode and why. Across four studies, participants were asked to evaluate different (...) types of real and hypothetical pronouns, including binary gender pronouns, race pronouns, and identity-neutral pronouns. We sampled participants from two languages with different pronoun systems: English (N = 1,120) and Turkish (N = 260). English pronouns commonly denote binary gender (e.g., he for men), whereas Turkish pronouns are identity-neutral (e.g., o for anyone). Participants’ reasoning about pronouns reflected both a familiarity preference (i.e., participants preferred the pronoun type used in their language) and—critically—participants’ social ideologies. In both language contexts, participants’ ideological beliefs that social groups are inherently distinct (essentialism) and should be hierarchal (social dominance orientation) predicted relatively greater endorsement of binary gender pronouns and race pronouns. A preregistered experimental study with an English-speaking sample showed that the relationship between ideology and pronoun endorsement is causal: Ideologies shape attitudes toward pronouns. Together, the present research contributes to linguistic and psychological theories concerning how people reason about language and informs policy-relevant questions about whether and how to implement language changes for social purposes.

Distributed Cognition and Integrational Linguistics have much in common. Both approaches see communicative activity and intelligent behaviour in general as strongly con- text-dependent and action-oriented, and brains as permeated by history. But there is some ten- sion between the two frameworks on three important issues. The majority of theorists of distributed cognition want to maintain some notions of mental representation and computa- tion, and to seek generalizations and patterns in the various ways in which creatures like us couple with technologies, (...) media, and other agents; many also want to offer explanations at subpersonal levels which may undercut the autonomy of personal-level accounts. In contrast, dominant views in integrational linguistics reject all invocation of representation, resist the explanatory search for similarity across contexts and moments, and see linguistics as a lay dis- cipline which should not offer explanations in terms alien to ordinary agents. On each of these issues, I argue that integrationists could move closer to the distributed cognition frame- work without losing the most important aspects of their view: integrationist criticisms of mainstream or classical theories can be respected while alliances with revised cognitivist views about representation, context, and explanation are developed.

This paper investigates the question of how to correctly capture the scope of singular thinking. The first part of the paper identifies a scope problem for the dominant view of singular thought maintaining that, in order for a thinker to have a singular thought about an object o, the thinker has to bear a special epistemic relation to o. The scope problem has it is that this view cannot make sense of the singularity of our thoughts about objects to which (...) we do not or cannot bear any special epistemic relation. The paper focuses on a specific instance of the scope problem by addressing the case of thoughts about the natural numbers. Various possible solutions to the scope problem within the dominant framework are assessed and rejected. The second part of the paper develops a new theory of singular thought which hinges on the contention that the constraints that need to be met in order to think singularly vary depending on the kind of object we are thinking about. This idea is developed in detail by discussing the difference between the somewhat standard case of thoughts about spatio-temporal medium-sized inanimate objects and the case of thoughts about the natural numbers. It is contended that this new Pluralist theory of singular thought can successfully solve the scope problem. (shrink)

Resumen La metáfora de la "descomposición" domina aún nuestra manera usual de pensar el análisis conceptual. Se trata de una herramienta muy útil para pensar este proceso tan abstracto, pero tiene limitaciones importantes. Por ejemplo, nos hace pensar que los componentes de un concepto deben estar en algún sentido contenidos en él o que la única manera en que dos conceptos pueden estar relacionados es que uno contenga al otro. Estas limitaciones no nos permiten dar cuenta de conceptos complejos cuya (...) estructura no es tan simple, como los de color o de medida. Por ello es tiempo de superar esta metáfora y pensar al análisis conceptual no sólo como descomposición, sino también como la asignación de diferentes funciones a los componentes de un concepto.Our customary way of thinking about conceptual analysis remains dominated by the metaphor of 'containment', which has certainly been very useful, but which also has important limitations. For example, it makes us think that the components of a concept must be, in some sense, contained in it or that the only way that two concepts can be related is if one contains the other. These limitations have not allowed us to account for concepts whose structure is not so simple, such as the concepts of color or measurement, among others. It is time, therefore, to overcome this metaphor and think of conceptual analysis not only as decomposition but also as the assignment of different functions to the components of a concept. (shrink)
