In [9] Mundici introduced a categorical equivalence Γ between the category of MV-algebras and the category of abelian [MATHEMATICAL SCRIPT SMALL L]-groups with strong unit. Using Mundici's functor Γ, in [8] the authors established an equivalence between the category of perfect MV-algebras and the category of abelian [MATHEMATICAL SCRIPT SMALL L]-groups. Aim of the present paper is to use the above functors to provide Yosida like representations of a large class of MV-algebras.

In this work we introduce a class of commutative rings whose defining condition is that its lattice of ideals, augmented with the ideal product, the semi-ring of ideals, is isomorphic to an MV-algebra. This class of rings coincides with the class of commutative rings which are direct sums of local Artinian chain rings with unit.

We describe a class of MV-algebras which is a natural generalization of the class of “algebras of continuous functions”. More specifically, we're interested in the algebra of frame maps Hom\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${_{\cal F}}$$\end{document} (Ω(A), K) in the category T of frames, where A is a topological MV-algebra, Ω(A) the lattice of open sets of A, and K an arbitrary frame.Given a topological space X and a topological MV-algebra A, we have the algebra C (...)

Among others we have the result: if K is spatial, then C(pt(K), A), pt(K) the points of K, embeds into Hom\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${_{\cal F}}$$\end{document} (Ω(A), K) analogous to the case of C (X, A) embedding into Hom\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${_{\cal F}}$$\end{document} (Ω(A), Ω (X)).

ABSTRACT In this paper we shall prove that l-rings are categorally equivalent to the MV*-algebras, a subcategory of perfect MV-algebras. We shall use this equivalence in order to characterize l-rings as quotients of certain semirings of matrices over MV*-algebras. We shall establish a relation between l-ideals in l-rings and some ideals in MV*-algebras. This edlows us to study the MV* f-algebras, a subclass of the MV*-algebras corresponding to the f-rings.

Embodied cognition often challenges standard cognitive science. In this outstanding introduction, Lawrence Shapiro sets out the central themes and debates surrounding embodied cognition, explaining and assessing the work of many of the key figures in the field, including George Lakoff, Alva Noë, Andy Clark, and Arthur Glenberg. Beginning with an outline of the theoretical and methodological commitments of standard cognitive science, Shapiro then examines philosophical and empirical arguments surrounding the traditional perspective. He introduces topics such as dynamic systems theory, (...) ecological psychology, robotics, and connectionism, before addressing core issues in philosophy of mind such as mental representation and extended cognition. Including helpful chapter summaries and annotated further reading at the end of each chapter, _Embodied Cognition_ is essential reading for all students of philosophy of mind, psychology, and cognitive science.

Stereotypes are false or misleading generalizations about groups, generally widely shared in a society, and held in a manner resistant, but not totally, to counterevidence. Stereotypes shape the stereotyper’s perception of stereotyped groups, seeing the stereotypic characteristics when they are not present, and generally homogenizing the group. The association between the group and the given characteristic involved in a stereotype often involves a cognitive investment weaker than that of belief. The cognitive distortions involved in stereotyping lead to various forms of (...) moral distortion, to which moral philosophers have paid insufficient attention. Some of these are common to all stereotypes—failing to see members of the stereotyped groups as individuals, moral distancing, failing to see subgroup diversity within the group. Other moral distortions vary with the stereotype. Some attribute a much more damaging or stigmatizing characteristic (e.g. being violent) than others (e.g. being good at basketball). But the characteristic in question must also be viewed in its wider historical and social context to appreciate its overall negative and positive dimensions. (shrink)

Thirty years ago, grounded cognition had roots in philosophy, perception, cognitive linguistics, psycholinguistics, cognitive psychology, and cognitive neuropsychology. During the next 20 years, grounded cognition continued developing in these areas, and it also took new forms in robotics, cognitive ecology, cognitive neuroscience, and developmental psychology. In the past 10 years, research on grounded cognition has grown rapidly, especially in cognitive neuroscience, social neuroscience, cognitive psychology, social psychology, and developmental psychology. Currently, grounded cognition appears to be achieving increased acceptance throughout cognitive (...) science, shifting from relatively minor status to increasing importance. Nevertheless, researchers wonder whether grounded mechanisms lie at the heart of the cognitive system or are peripheral to classic symbolic mechanisms. Although grounded cognition is currently dominated by demonstration experiments in the absence of well-developed theories, the area is likely to become increasingly theory driven over the next 30 years. Another likely development is the increased incorporation of grounding mechanisms into cognitive architectures and into accounts of classic cognitive phenomena. As this incorporation occurs, much functionality of these architectures and phenomena is likely to remain, along with many original mechanisms. Future theories of grounded cognition are likely to be heavily influenced by both cognitive neuroscience and social neuroscience, and also by developmental science and robotics. Aspects from the three major perspectives in cognitive science—classic symbolic architectures, statistical/dynamical systems, and grounded cognition—will probably be integrated increasingly in future theories, each capturing indispensable aspects of intelligence.

This article focuses on ethical issues surrounding the selling and buying of human organs. The author argues that most people who sell their organs in India do so in order to pay already existing debts. The transaction is only temporarily an exchange of “life for life,” and most “donors” are back in debt soon after the operation. The author discusses the flexible ethics that reduce reality to dyadic transactions and the purgatorial ethics that collapse real and imaginary exploitation in the (...) service of complex interests. He also offers a sophisticated discussion of the ethics of publicity and public ethics. He emphasizes the lack of factual information, intentional manipulation of information, and the dissemination of kidney panics and kidney scandals, especially by the new developing bioauthorities and bioethical brokers.

The words ‘racist’ and ‘racism’ have become so overused that they nowconstitute obstacles to understanding and interracial dialogue about racial matters. Insteadof the current practice of referring to virtually anything that goes wrong or amiss withrespect to race as ‘racism,’ we should recognize a much broader moral vocabulary forcharacterizing racial ills – racial insensitivity, racial ignorance, racial injustice, racialdiscomfort, racial exclusion. At the same time, we should fix on a definition of ‘racism’ thatis continuous with its historical usage, and avoids (...) conceptual inflation. I suggest two basic,and distinct, forms of racism that meet this condition – antipathy racism and inferiorizingracism. We should also recognize that not all racially objectionable actions are done froma racist motive, and that not all racial stereotypes are racist. (shrink)

Catholic doctrine’s strict prohibition on abortion can lead clinicians or institutions to conscientiously refuse to provide abortion, although a legal duty to provide abortion would apply to anyone who refused. Conscientious refusals by clinicians to end a pregnancy can constitute murder or reckless homicide under American law if a woman dies as a result of such a refusal. Such refusals are not immunized from criminal liability by the constitutional right to the free exercise of religion or by statutes that confer (...) immunity from criminal homicide prosecution. Core principles of the rule of law require the state to protect the lives of all persons equally and to place the life and health of persons above any the interests of providers have in moral integrity or in respecting the moral status of prenatal humans. In some states criminal liability related to conscientious objection also applies to corporate hospital officials. (shrink)

I defend the doctrine of double effect and a so-called ‘strict’ definition of intention: A intends an effect if and only if A has it as an end or believes that it is a state of affairs in the causal sequence that will result in A's end. Following Kamm's proposed ‘doctrine of triple effect’, I distinguish an intended effect from an effect that motivates an action, and show that this distinction is morally significant. I use several contrived cases as illustrations, (...) but my position does not depend on intuitive judgements about them. Instead, it follows from the view that the moral permissibility of an action depends at least partly on how it forms the agent's character. I also respond to some objections presented by Harris, Bennett, McIntyre, Thomson and Scanlon to the doctrine of double effect. (shrink)

Semantic originalism is a theory of constitutional meaning that aims to disentangle the semantic, legal, and normative strands of debates in constitutional theory about the role of original meaning in constitutional interpretation and construction. This theory affirms four theses: (1) the fixation thesis, (2) the clause meaning thesis, (3) the contribution thesis, and (4) the fidelity thesis. -/- The fixation thesis claims that the semantic content of each constitutional provision is fixed at the time the provision is framed and ratified: (...) subsequent changes in linguistic practice cannot change the semantic content of an utterance. -/- The clause meaning thesis claims that the semantic content is given by the conventional semantic meaning (or original public meaning) of the text with four modifications. The first modification is provided by the publicly available context of constitutional utterance: words and phrases that might be ambiguous in isolation can become clear in light of those circumstances of framing and ratification that could be expected to known to interpreters of the Constitution across time. The second modification is provided by the idea of the division of linguistic labor: some constitutional provisions, such as the natural born citizen clause may be terms of art, the meaning of which are fixed by the usages of experts. The third modification is provided by the idea of constitutional implicature: the constitution may mean things it does not explicitly say. The fourth modification is provided by the idea of constitutional stipulations: the constitution brings into being new terms such as House of Representatives and the meaning of these terms is stipulated by the Constitution itself. -/- The contribution thesis asserts that the semantic content of the Constitution contributes to the law: the most plausible version of the contribution thesis is modest, claiming that the semantic content of the Constitution provides rules of constitutional law, subject to various qualifications. Our constitutional practice provides strong evidence for the modest version of the contribution thesis. -/- The fidelity thesis asserts that we have good reasons to affirm fidelity to constitutional law: virtuous citizens and officials are disposed to act in accord with the Constitution; right acting citizens and officials obey the constitution in normal circumstances; constitutional conformity produces good consequences. Our public political culture affirms the great value of the rule of law. -/- We can summarize semantic originalism as a slogan: The original public meaning of the constitution is the law and for that reason it should be respected and obeyed. The slogan recapitulates each of the claims made by semantic originalism, but it is potentially misleading because it does not clearly distinguish between the semantic claims made by the fixation and clause meaning theses, the legal claim made by the contribution thesis, and the normative claim made by the fidelity thesis. -/- Part I introduces the four theses. Part II is entitled An Opinionated History of Constitutional Originalism, and it provides the context for all that follows. Part III is entitled Semantic Originalism: A Theory of Constitutional Meaning, and it lays out the case for original public meaning as the best nonnormative theory of constitutional content. Part IV is entitled The Normative Implications of Semantic Originalism, and it articulates a variety of normative arguments for originalism. Part V is entitled Conclusion: Semantic Originalism and Living Constitutionalism, and it explores the broad implications of semantic originalism for living constitutionalism and the future of constitutional theory.

_Property Rights: Philosophic Foundations,_ first published in 1977, comprehensively examines the general justifications for systems of private property rights, and discusses with great clarity the major arguments as to the rights and responsibilities of property ownership. In particular, the arguments that hold that there are natural rights derived from first occupancy, labour, utility, liberty and virtue are considered, as are the standard anti-property arguments based on disutility, virtue and inequality, and the belief that justice in distribution must take precedence over (...) private ownership. Lawrence Becker goes on to contend that there are four sound lines of argument for private property that, together with what is sound in the anti-property arguments, must be co-ordinated to form the foundations of a new theory. He therefore expounds a concise but sophisticated theory of property that is relevant to the modern world, and concludes by indicating some of the implications of his theory. (shrink)

The Doctrine of Temporal Parts (sometimes abbreviated herein as 'DTP') asserts that, for each portion (including infinitely small portions) of the smallest period of time during which a material object exists, there is an object-a temporal part of the material object in question-which exists at that and at no other time. In "Things Change," Mark Heller offers an argument for DTP, and responds to a objection, the "No-Change" objection, to that doctrine.2 My goal in this paper is to undermine both (...) Heller's argument in favor of DTP and his response to that criticism. (shrink)

The standard philosophical and folk-psychological accounts of cognition and action credit us with too much spontaneity in our activities and projects. We are taken to be fundamentally active rather than reactive, to project our needs and aims and deploy our full supporting arsenal of cognitive instruments upon an essentially passive environment. The corrected point of view presented here balances this image of active agency with an appreciation of how we are also continually responding to the world, that is, to the (...) pragmatic situations that effectively select subsets of our cognitive resources to be at our disposal in generating responses. The result is a superseding of the standard Cognitive Integrationist picture by a model of a structurally divided mind, comprising a multiplicity of diverse and sometimes-conflicting standpoints, personas, and wills whose elicitation is a complex function of agent intentions and plans, the encountered environment, past experience, and temporal sequence. According to this model, the manifold stored representations constituting a person’s cognitive endowment do not form a single integrated network all equally ready for use. Cognition at any given moment is limited to drawing upon only a subset of one’s perspective, the perspect that is activated in accordance with the specific mental task or situation (the pragmatic context) that one perceives oneself to be facing. The system enlists the environmental context as trigger for practical and theoretical activity, based upon the agent’s prior experience. Though susceptible to certain kinds of error, and not inherently inclined toward innovative thinking, it enables the generally efficient use of our enormous cognitive endowments in conducting our lives in real time.

____Politics, Philosophy, Culture__ contains a rich selection of interviews and other writings by the late Michel Foucault. Drawing upon his revolutionary concept of power as well as his critique of the institutions that organize social life, Foucault discusses literature, music, and the power of art while also examining concrete issues such as the Left in contemporary France, the social security system, the penal system, homosexuality, madness, and the Iranian Revolution.

Measurement of scientific productivity is difficult. The measures used (impact factor of the journal, citations to the paper being measured) are crude. But these measures are now so universally adopted that they determine most things that matter: tenure or unemployment, a postdoctoral grant or none, success or failure. As a result, scientists have been forced to downgrade their primary aim from making discoveries to publishing as many papers as possible—and trying to work them into high impact factor journals. Consequently, scientific (...) behaviour has become distorted and the utility, quality and objectivity of articles has deteriorated. Changes to the way scientists are assessed are urgently needed, and I suggest some here. (shrink)

Ever since Greek antiquity "disembodied knowledge" has often been taken as synonymous with "objective truth." Yet we also have very specific mental images of the kinds of bodies that house great minds--the ascetic philosopher versus the hearty surgeon, for example. Does truth have anything to do with the belly? What difference does it make to the pursuit of knowledge whether Einstein rode a bicycle, Russell was randy, or Darwin flatulent? Bringing body and knowledge into such intimate contact is occasionally seen (...) as funny, sometimes as enraging, and more often just as pointless. Vividly written and well illustrated, Science Incarnate offers concrete historical answers to such skeptical questions about the relationships between body, mind, and knowledge. Focusing on the seventeenth century to the present, Science Incarnate explores how intellectuals sought to establish the value and authority of their ideas through public displays of their private ways of life. Patterns of eating, sleeping, exercising, being ill, and having (or avoiding) sex, as well as the marks of gender and bodily form, were proof of the presence or absence of intellectual virtue, integrity, skill, and authority. Intellectuals examined in detail include René Descartes, Isaac Newton, Charles Darwin, and Ada Lovelace. Science Incarnate is at once very funny and deeply serious, addressing issues of crucial importance to present-day discussions about the nature of knowledge and how it is produced. It incorporates much that will interest cultural and social historians, historians of science and medicine, philosophers, sociologists, and anthropologists. (shrink)

Hans Jonas accuses Heidegger of “never bring[ing] his question about Being into correlation with the testimony of our physical and biological evolution.” Neither the early nor later Heidegger has a “philosophy of nature,” Jonas charges, because Naturphilosophie demands a new concept of matter, a monistic account of cosmogony and evolution, and the grounding of ethical responsibility for future generations in an ontological “first principle.” Jonas’s ontological rethinking of Darwinism allows him to overcome the nihilism that a mechanistic interpretation of evolution (...) forces upon us: a nihilism allegedly shared by Heidegger. I imagine a Heideggerian response to Jonas, and ask whether the dream of recovering a synthesis between cosmogony and moral insight has been irrecoverably shattered by modern natural science.

In this chapter, we consider, and reject, the claim that all elderly patients’ desires for suicide are irrational. The same reasons that have led to a growing acceptance for the rationality of suicide in terminal cases should lead us to view other desires for suicide as possibly rational. In both cases, desires for suicide can and do materialize in the absence of mental illness. Furthermore, we claim that desires for suicide can remain rational even in the face of some mental (...) illnesses so long as four criteria are met: individuals must demonstrate rationality, have realistic information and judgments about their life-world, be in a state of mind (e.g., their emotions and will) that is not be severely compromised by mental illness, and make choices that are congruent with their fundamental values and critical interests. We conclude that some rational suicides can be ethically justifiable. (shrink)

Manuel Velasquez and F. Neil Brady apply the doctrine of double effect to business ethics and conclude that the doctrine allows a pharmaceutical company to sell a drug with potentially fatal side effects only if it also has the good effect of saving lives. This forbidsthe sale of many common products, such as automobiles and alcohol. My account preserves the virtues of the doctrine of double effectwithout making it too restrictive. I apply the doctrine to a pharmaceutical company’s decision to (...) market a drug with dangerous side effects and argue that free markets often offer the best way to compare the good and bad effects of business decisions. I conclude that the doctrine does allow a business to sell a potentially fatal product that does not save lives, provided that it warns consumers about the danger. (shrink)

If racism is a matter of possessing racist beliefs, then it would seem that its cure involves purging one’s mind of all racist beliefs. But the truth is more complicated, and does not permit such a straightforward strategy. Racist beliefs are resistant to subjective repudiation, and even those that are so repudiated are resistant to lasting expulsion from one’s belief system. Moreover, those that remain available for use in cognition can shape thought and behavior even in the event that one (...) has recognized their falsehood. Yet if one is intent upon combating the racism within one’s mind, one is not without effective cognitive countermeasures that can render one’s racist beliefs ineffectual. (shrink)

Librarians often object to Internet filters on the grounds that filters are prone to overblocking and underblocking. This argument implies that a significant problem with contemporary filters is that they are insufficiently fine-grained. In this article, we posit that present-day filters will always be conceptually capable of failure, regardless of how granular their content analysis becomes. This is because, we argue, objections to content are best understood as objections to problematic interactions between content and particular knowers. We import the concept (...) of the situated knower from feminist epistemology to capture the heterogeneous, socially embedded nature of patrons, about whom we cannot make blunt generalizations for filtering purposes. A successful filter would need information about these differently situated patrons, the content they seek, and the interactions between the two. We conclude that a genuinely successful Internet filter would therefore need to be both mind reading and fortune-telling. (shrink)
