The mechanism by which the mammalian kidney creates the osmotic gradient necessary for urine concentration remains an open question. We present a brief survey of the give-and-take between theory and experiment on this question over the last half century. We start with the introduction of the countercurrent multiplier paradigm in 1951. We finish with a description of a recent suggestion that the explanation for the enigmatic inner medullary osmotic gradient may reside in the very metabolism of the inner medullary cells, (...) which are required by the region's hypoxia to obtain their ATP largely from anaerobic glycolysis and which thus, by the same token, furnish net osmoles to the medullary interstitium by convering glucose to lactate.

The classic model of blood pressure regulation by Guyton et al. (Annu Rev Physiol 34:13–46, 1972a; Ann Biomed Eng 1:254–281, 1972b) set a new standard for quantitative exploration of physiological function and led to important new insights, some of which still remain the focus of debate, such as whether the kidney plays the primary role in the genesis of hypertension (Montani et al. in Exp Physiol 24:41–54, 2009a; Exp Physiol 94:382–388, 2009b; Osborn et al. in Exp Physiol 94:389–396, 2009a; Exp (...) Physiol 94:388–389, 2009b). Key to the success of this model was the fact that the authors made the computer code (in FORTRAN) freely available and eventually provided a convivial user interface for exploration of model behavior on early microcomputers (Montani et al. in Int J Bio-med Comput 24:41–54, 1989). Ikeda et al. (Ann Biomed Eng 7:135–166, 1979) developed an offshoot of the Guyton model targeting especially the regulation of body fluids and acid–base balance; their model provides extended renal and respiratory functions and would be a good basis for further extensions. In the interest of providing a simple, useable version of Ikeda et al.’s model and to facilitate further such extensions, we present a practical implementation of the model of Ikeda et al. (Ann Biomed Eng 7:135–166, 1979), using the ODE solver Berkeley Madonna. (shrink)

A dominant area of inquiry within intergenerational ethics concerns how goods ought to be justly distributed between noncontemporaries. Contractualist theories of justice that have broached these discussions have often centered on the concepts of mutual advantage and reciprocal cooperation between rational, self‐interested beings. However, another prominent reason that many in the present feel that they have obligations toward future generations is not due to self‐interested reciprocity, but simply because they care about what happens to them. Care ethics promises to be (...) conceptually well‐suited for articulating this latter reason: given that future generations are in a perpetual condition of dependency on present‐day people's actions, this is precisely the kind of relational structure that care theorists should be interested in morally evaluating. Unfortunately, the care literature has been largely silent on intergenerational ethics. This article aims to advance this literature, offering the blueprints of what a care ethic concerning future generations—a “future care ethic”—should look like. The resultant ethic defends a sufficientarian theory of obligation: people in the present ought to ensure the conditions needed to encourage and sustain a world that enables good caring relations to flourish.

Care theorists have yet to outline an account of how the concept of toleration should function in their normative framework. This lack of outline is a notable gap in the literature, particularly for demonstrating whether care ethics can appropriately address cases of moral disagreement within contemporary pluralistic societies; in other words, does care ethics have the conceptual resources to recognize the disapproval that is inherent in an act of toleration while simultaneously upholding the positive values of care without contradiction? By (...) engaging care ethics with John Locke’s influential corpus on toleration, I answer the above question by building the bases for a novel theory of toleration as care. Specifically, I argue that care theorists can home in on an oft-overlooked aspect of Locke’s later thought: that the possibility of a tolerant society is dependent on a societal ethos of trustworthiness and civility, to the point where Locke sets out positive ethical demands on both persons and the state to ensure this ethos can grow and be sustained. By leveraging and augmenting Locke’s thought within the care ethical framework, I clarify how care ethics can provide meaningful solutions to moral disagreement within contemporary pluralistic societies in ways preferable to the capability of a liberal state.

In The Ethics of Care, Virginia Held explores what values of care might fulfil normative criteria for evaluating the moral worth of relations. Held identifies seven potential values: attentiveness, empathy, mutual concern, sensitivity, responsiveness, taking responsibility, and trustworthiness. Though Held’s work is helpful as a starting point for conceptualizing some normative criteria, two problems need addressing. First, Held does not provide sufficient justification for why these potential values ought to be considered genuine values in the care ethical framework. Second, Held (...) overlooks two other potential values cited in the care literature: competence and respect. This paper builds upon Held’s work to offer a more coherent understanding of the values of care. It does so by scrutinizing and conceptually organizing the above nine potential values. Of these nine, only four are considered genuine values: attentiveness, mutual concern, responsiveness, and trustworthiness. It is concluded that good caring relations are those that exemplify the four values of care in their deliverance of caring practices. (shrink)

A central focus of care ethics is on the compelling moral salience of attending to the needs of our particular others. However, there is no consensus within the care literature for how and when such partiality is morally justified. This article outlines and defends a novel justificatory argument that grounds partiality in the facts and values of the relation itself. Specifically, this article argues that partiality is justified when grounded in caring values exemplified in good caring relations. Hence, this justification (...) is termed the argument from good caring relations. This justification is promising for two reasons. First, the argument from good caring relations has the potential to spur engagement between care ethics and the broader partiality literature. In particular, the argument from good caring relations could enhance what Simon Keller has termed ‘the relationships view’. Second, the argument from good caring relations is more persuasive than the other major justificatory argument for partiality presently in the care literature: a distributive argument, which takes the form of a modified version of Robert Goodin’s assigned responsibility model of moral obligation. Indeed, where this distributive argument fails, the argument from good caring relation succeeds. This article thus concludes that the argument from good caring relations is preferable for justifying partiality in care ethics. (shrink)

This paper seeks to provide a literary review of advancements in climate change ethics, primarily concerning the issue of climate justice.

Blair equates the constructs of working memory (WM), executive function, and general fluid intelligence (gF). We argue that there is good reason not to equate these constructs. We view WM and gF as separable but highly related, and suggest that the mechanism behind the relationship is controlled attention – an ability that is dependent on normal functioning of the prefrontal cortex.

Hahn held on February 19, 2005, and were compiled for presentation here by Sharon (Hahn) Crowell.A Tribute to Dr. Lewis E. Hahn (1908-2004) from a Global PerspectiveGeorge C. H. Sun President, Thomé H. Fang Institute, Inc., Mobile, AlabamaAmong the philosophical community in both the East and the West, no word of introduction is needed for our beloved Master, who was the recipient of numerous distinctions and honors, with titles that included "Man of the Year in Philosophy" and "Award of Lifetime Achievement." The very name "Lewis E. Hahn" itself already stands now for genuineness, dedication, and fulfillment.A great work is a dialogue with eternity; a great person is such a work. In less than thirty years he succeeded in developing Carbondale from what had been a small college town in the Midwest into the Mecca of American philosophy. His most important achievements were the Dewey Center and the Pepper Archives that he helped install at SIUC These, among other such institutions, will remain a unique contribution, a glory of American philosophy, and a monument in the history of human thought.For posterity Lewis E. Hahn will remain an object of wonder and amazement. How is it possible for one human being to have accomplished so much, so well, and in so short a span of time—less than one century—in breadth, depth, and diversity? Some one hundred years ago, by bridging the gap between the New World and the Old, William James was hailed as the great genius of international friendship among philosophical thinkers, but we now find a greater genius in Lewis E. Hahn, who succeeded in bringing together the peoples of East and West from at least four continents: Europe, Australia, America (both North and Latin America), and Asia. To my knowledge, few of his predecessors and contemporaries have been half so widely read and liberal-minded as he was, in view of the range and scope of the Library of Living Philosophers that he helped continue after the passing of its founder, Dr. Paul A. Schilpp.What type of man was Hahn, our younger generation will wonder? Only a pluralist approach can help us understand the true character of such a legendary pluralist-contextualist. In short, he was "a full personality." As I recall, while working on my dissertation with him in the 1970s, we had a brief discussion on Confucius, the sage of ancient China. "A full personality!" was his laconic assessment. Suddenly I realized, to quote the Analects: "The Master is talking about himself!" For, as the Buddhists put it, only a Buddha can understand a Buddha. Or, as William James put it, only one who has philosophy can appreciate philosophy. Many friends [End Page 1] of my generation admire him so much; Te Chen of Hong Kong calls him "a great Confucian in America." Those who regret the loss of many precious Confucian virtues in China today have now rediscovered them in the person of Lewis E. Hahn! If Nietzsche called Kant "a great Chinese in Königsberg," it is simply because he had not encountered our own Master.A paradigm of academic leadership, Dr. Hahn is simply irreplaceable—this is a tribute I personally heard in Carbondale in the late 1960s. It is not an exaggeration to say that he was a superb administrator, and he could have been the best Secretary of the State we ever had, for he possessed more in the way of philosophical wisdom than all his predecessors put together! As a great teacher, he was no less "serene, good, learned, wise, and ardent" than... (shrink)

Applying Thomas Aquinas’s account of the intellectual virtue of art to teaching yields valuable results both for those who wish to understand teaching better and those looking for models of the approach to virtue epistemology Roberts and Wood call “regulative.” To vindicate that claim, this article proceeds in four steps: First, I introduce Thomas’s taxonomy of the intellectual virtues in light of a pair of distinctions between practical and speculative knowledge and between immanent and transient operations. In the (...) second section, I consider teaching’s relation to each of Thomas’s intellectual virtues and argue that it belongs most properly to art. Next, I describe Thomas’s taxonomy of art by distinguishing among four cross-cutting categories that characterize species of that virtue. Finally, I outline an account of the art of teaching that treats it, with respect to those categories, as performative, deliberative, cooperative, and intersubjective. (shrink)

Abstract:This article repositions Thomas Arnold as a major nineteenth-century historian through an analysis of his most important work, the History of Rome (1838–42). While scholars have focused primarily on Arnold's role as headmaster of Rugby School and Liberal Anglican theologian, I examine his historical contribution in the context of the Romantic movement. Building on the work of B. G. Niebuhr and Giambattista Vico, Arnold interpreted the contest between the patricians and plebeians at Rome as emblematic of a universal class (...) struggle, in which failure to find a compromise between the rich and the poor would inevitably lead to disaster.

In this volume, Randall B. Smith provides a revisionist account of the scholastic culture that flourished in Paris during the High Middle Ages. Exploring the educational culture that informed the intellectual and mental habits of Thomas Aquinas and Bonaventure, he offers an in-depth study of the prologues and preaching skills of these two masters. Smith reveal the intricate interrelationships between the three duties of the master: lectio (reading), disputatio (debate), and praedicatio (preaching). He also analyzes each of Aquinas (...) and Bonaventure's prologues from their student days to their final works, revealing both their artistry and their instructional character. Written in an engaging style, this book serves as an invaluable resource that will enable scholars and students to read thirteenth-century sermons, prologues, and biblical commentaries with greater understanding and ease.

In lieu of an abstract, here is a brief excerpt of the content:Bonaventure's Inception Address as Regent Master at Paris:Omnium ArtifexRandall B. SmithInception as Master and the Principium in AulaAfter nineteen years of study at the University of Paris—six in the study of Arts (1235–1241), two lecturing in the Arts (1241–1243), five as auditor theologiae (1243–1248), two as a baccalarius biblicus and as a lector biblicus for the Franciscans (1248–1251), two as a baccalarius sententiarius (1251–1253), and one as a baccalarius (...) formatus (1253–1254)—Bonaventure of Bagnoregio was incepted as magister regens (regent master) around Easter (12 April) in 1254 to replace William of Middleton in the Franciscan chair at the University of Paris.1At that time, the inception ceremonies for an incoming regent master consisted of several parts. On the appointed day, the candidate would be officially received by the chancellor of the university in the ceremonial hall, the aula, of the bishop before the assembled faculty and students of the university. The previous evening would have been spent responding to bachelors and masters in a complex series of "disputed questions."2 But on the morning of the next day, the presiding master would have stood and placed on Bonaventure's head a biretta and said aloud: "I place on you the magisterial biretta in the name of the Father, and of the Son, and of the Holy Spirit. Amen." After birettas had been distributed to the other masters to place on their own heads, the gathered company sat down to hear the new master deliver his inaugural lecture, the principium in aula.According to University regulations, the principium address was to be a praise of sacred Scripture, and although it was one of the high [End Page 211] points in the inception ceremony, the inception address was supposed to be delivered "briefly" (breve) and "quickly terminated" (celeriter terminato).3 When Friar Thomas Aquinas incepted in 1256, two years after Bonaventure, his principium address was completed in about ten minutes. Brother Bonaventure's principium, a translation of which follows this introduction, would require about forty minutes or more to read out loud. But then, as Aquinas himself might have said, "briefly" can be said in several ways.4 A study of earlier principium addresses by other masters shows, moreover, that the length of these addresses varied from master to master.5The Principium in Aula and the Sermo Modernus StyleThe earliest records we have of masters who incepted at Paris reveal that their inception principia addresses were always delivered in the contemporary style of preaching, the so-called "sermo modernus" or "modern sermon" style. There is no need for our present purposes to trace the development of the sermo modernus style, other than to say that its origins lie in the late twelfth and early thirteenth century, and that it had become highly developed, with numerous preaching manuals and reference materials to help preachers master its forms, by the time Thomas and Bonaventure were incepted as masters at Paris, in 1256 and 1254 respectively.6 [End Page 212]In brief, three things were especially characteristic of these thirteenth century sermo modernus style sermons: (1) the thema, a biblical verse, usually from the day's readings that the preacher would use to lend structure and order to the entire sermon; (2) the divisio of the thema, and (3) the dilatatio of each of the parts created by this opening divisio.7The thema verse served as a structuring device which provided an outline of the topics to be covered in the sermon. When the sermon was preached, the thema verse also served as a mnemonic device to help the listeners identify their place within the progress of the whole and then recall the contents of the sermon after it was finished. To recall the contents of the sermon, one merely had to bring to mind the opening thema verse, and each word would suggest the topics the preacher had associated with it.8So, for example, in the principium address Bonaventure delivered at his inception as master, Bonaventure took as his opening thema a verse from Wisdom 7:1, Omnium artifex docuit me sapientia ("The maker of all things...

Thomas Reid's Essays on the Active Powers presents what is probably the most thoroughly developed version of agent-causal libertarianism in the modern canon. While commentators today often acknowledge Reid's contribution, they typically focus on what appears to be a serious problem for the view: Reid appears to commit himself to a position according to which acting freely would require an agent to engage in an infinite number of exertions of active power. In this essay, we maintain that, properly understood, (...) Reid's version of agent-causal libertarianism generates no regress of exertion. Our discussion begins by presenting Reid's account of free action and why it appears vulnerable to a worrisome regress. We then consider three attempts to address the regress in the contemporary literature offered by William Rowe, Gideon Yaffe, and James Van Cleve, which we find unsatisfactory. We then develop a solution to the worry—one that takes very seriously both what Reid means by an ‘efficient’ cause and his appeal to normative features when explaining action. We call it the ‘networked capacity’ view. (shrink)

In The Structural Transformation of the Public Sphere, Habermas makes the claim that the unprecedented public use of critical reason was an essential constituent of the early modern European (bourgeois) public sphere (1991, 27-28, 105-6, and more generally 1-117). Narrating the history of the particular concept of critical reason that animated the public sphere, Habermas locates its origin in the practical reason (phronesis) of Aristotle but argues that Niccolò Machiavelli and Thomas More had drastically transformed the concept when they (...) substituted for phronesis a practical reason based instead on techne (1973, 42, 50-51). Machiavelli's role was central in this transformation, for he "reduces the practical .. (shrink)

Thomas Reid has the unusual distinction of arriving at a metaethical position very much like G. E. Moore’s via a route very similar to that employed by the Kantians. That is, Reid embraces a version of nonnaturalist moral realism by appeal not to open question-style considerations but to a particular account of agency. In this essay, we reconstruct Reid’s agency-centered argument for his constitutivist version of moral nonnaturalism, highlighting its commitments. Having presented Reid’s argument, we close by considering a (...) prominent contemporary Kantian view, namely, Christine Korsgaard’s, and identifying where, despite their common commitments, Reid and Korsgaard part company. The comparison, we suggest, is instructive because it allows us to see more clearly why the link between agency-centered approaches to ethical theorizing and nonrealist, constitutivist views of morality, such as Korsgaard’s, is deeply contingent.

In Justice, Care, and Value Thomas Randall advances the radical potential of care ethics as a distinct (and preferable) theory of distributive justice. Advancing the care ethical literature this book defends a vision of society that can best enable such relations to flourish. Specifically, Randall uses breakthrough arguments to propose a values-driven theory of care ethics that identifies good caring relations through classifying the values of care. He argues that such a theory gives us unique and meaningful (...) solutions to contemporary questions and encourages us to think about distributive justice across personal, political, global, and intergenerational domains. Through this the book makes significant strides to engage care ethics with the broader moral and political philosophy literature. Topical and interdisciplinary, Randall demonstrates that care ethics has the conceptual resources to ground distributive theories of socialism, territorial and natural resource rights, obligations to future generations, and historic redress. The book will be of great interest for academics, researchers, and students in feminist philosophy, but also in liberalism, global and intergenerational theories of justice, and political economy.

Care ethics is often criticized for being incapable of outlining what responsibilities we have to persons beyond our personal relations, especially toward distant others. This criticism centres on care theorists’ claim that the concerns of morality emerge between people, generated through our relations of interdependent care: it is difficult to see how moral duties can be applied to those with whom we do not forge a relationship. In this article, I respond to this criticism by outlining a care ethical justification (...) for an interest theory of human rights. This theory will argue that the demands of global justice include various positive actions that aim toward ensuring the conditions for good caring relations to flourish, which in turn protect and promote the vital interests of all persons. In doing so, I aim to concurrently advance the sparse work on human rights within the care literature, systematizing the ideas of care theorists such as Daniel Engster, Virginia Held, and Fiona Robinson.

The treatment decisions of competent adults, especially treatment refusals, are generally respected. In the case of minors something turns on their age, and older minors ought increasingly to make their own decisions. On the other hand, parents decide on behalf of infants and young children. Their right to do so can best be justified in terms of the importance of preserving intimate family relationships, rather than in terms of the child's best interests, although the child's best interests will most often (...) follow from this arrangement. Nevertheless, there are and ought to be legal, ethical, and financial constraints on parental decision making. (shrink)

There has been a long-standing debate in philosophy and psychology about the role of representation in visual perception. Here, we argue on the basis of evidence from philosophy, psychology, and neuroscience that episodic and schematic memory representations are pivotal to the visual perception of objects and scenes. In the visual perception of objects and scenes, sensory information is initially matched with object and scene templates, or schemas, in long-term memory. The most relevant representations are then selected for encoding in working (...) memory. We furthermore argue that activations of episodic memory representations contribute to the fineness of grain of visual representations. The representational view of visual perception that emerges is what we call the "template tuning view." According to this view, prior information – specifically, long-term memories – shape the representational content of visual perception. In the final section of the chapter, we argue that unlike representational conceptions of visual perception, naïve and direct realist theories have difficulties accommodating these findings.

A new picture is emerging from the last hundred years’ study of evolution. Mountains of data to support—or bury—perspective are available, and there have been some substantial, recent summative works. Darlington in particular is recognized not only for comprehensiveness and insight, but for wit and clarity as well. Dobzhansky has done a rather lucid summary in nontechnical language, and Rensch has constructed a monument of documentation and intricate interpretation. Nevertheless, the picture of evolution has changed far more drastically than most (...) professionals can grasp without thoroughly digesting and independently interpreting a host of summative literature. The war-of-all-against-all, which is still evolution for the layman, has long since given away to the ecologist’s community with its various kinds of relationships. Therefore, the concept of “Biological Expansion” is now felt to be a more adequate frame of reference. (shrink)

Twelve-step programs such as Alcoholics Anonymous and Narcotics Anonymous invite members to trust that what is said in meetings remains confidential. However, the New York Times, a prominent and influential newspaper, has breached that confidentiality, offering both a precedent and a rationale to other media including newspapers, cable news programs, internet news blogs, and so on. This prominent breach may influence not only other news media but also the trust that 12-step members have in their programs.
