The Ethics Code of the American Psychological Association is a bedrock of the profession. The contextual factors of society affect the Ethics Code of the APA, resulting in an ever-changing document. The context of the reorganization of the APA after World War II created an initial impetus toward a formalized code. A key contextual feature of the Code's development was the use of the Critical Incident Technique, which was based in the empirical aspirations of the psychological field. This article explores (...) the historical context around the APA's decision to draft an ethics code, reviews its development, and discusses its role for psychologists today. (shrink)

Hip implants have provided life-changing treatment, reducing pain and improving the mobility and independence of patients. Success has encouraged manufacturers to innovate and amend designs, engendering patient hopes in these devices. However, failures of medical implants do occur. The failure rate of the Articular Surface Replacement metal-on-metal hip system, implanted almost 100,000 times world-wide, has re-opened debate about appropriate and timely implant governance. As commercial interests, patient hopes, and devices' governance converge in a socio-technical crisis, we analyse the responses of (...) relevant governance stakeholders in the United Kingdom between 2007 and 2014. We argue that there has been a systemic failure of the governance system entrusted with the safety of patients fitted with medical implants. Commercial considerations of medical implants and the status quo of medical implant governance have been given priority over patient safety despite the availability of significant failure data in an example of uncertainty about what constitutes appropriate precautionary action.

Emily Dickinson is the most paradoxical of poets: the very poet of paradox. By way of voluminous biographical material, not to mention the extraordinary intimacy of her poetry, it would seem that we know everything about her; yet the common experience of reading her work, particularly if the poems are read sequentially, is that we come away seeming to know nothing. We could recognize her inimitable voice anywhere—in the “prose” of her letters no less than in her poetry—yet it is (...) a voice of the most deliberate, the most teasing anonymity. “I’m Nobody!” is a proclamation to be interpreted in the most literal of ways. Like no other poet before her and like very few after her—Rilke comes most readily to mind, and, perhaps, Yeats and Lawrence—Dickinson exposes her heart’s most subtle secrets; she confesses the very sentiments that, in society, would have embarrassed her dog . Yet who is this “I” at the center of experience? In her astonishing body of 1,775 poems Dickinson records what is surely one of the most meticulous examinations of the phenomenon of human “consciousness” ever undertaken. The poet’s persona—the tantalizing “I”—seems, in nearly every poem, to be addressing us directly with perceptions that are ours as well as hers. The poems’ refusal to be rhetorical, their daunting intimacy, suggests the self-evident in the way that certain Zen koans and riddles do while being indecipherable. But what is challenged is, perhaps, “meaning” itself: Wonder—is not precisely KnowingAnd not precisely Knowing not—A beautiful but bleak conditionHe has not lived who has not felt—Suspense—is his maturer Sister—Whether Adult Delight is PainOr of itself a new misgiving—This is the Gnat that mangles men— [1331, ca. 1874]1 1.

In lieu of an abstract, here is a brief excerpt of the content:The Puzzle of Fanny PriceJoyce L. JenkinsIt is common to open a work regarding the merits of Mansfield Park by noting that Fanny Price is very difficult to like. Nietzsche might have described her as a "moral tarantula." 1 She sits, making negative moral judgments about the actions of others, while doing nothing herself. Fanny spends most of her time, literally, sitting or lying down. Austen describes her character (...) as "supine." Comparing Fanny with her sister Susan, Austen says that "Susan was only acting on the same truths, and pursuing the same system, which her [Fanny's] own judgment acknowledged, but which her more supine and yielding temper would have shrunk from asserting. Susan tried to be useful, where she could only have gone away and cried" (MP, p. 395). 2 And Fanny cries all of the time. She cries at least thirteen times over the course of the novel. So, there are two questions about the novel that need to be answered. Why did Austen create a heroine who is so clearly distasteful? Why do some critics and philosophers see Fanny as a moral ideal or cultural icon? Some (Alasdair MacIntyre, Gilbert Ryle, Lionel Trilling) argue that Fanny is so unappealing just because Austen wants to be didactic 3 and force us to focus on virtue. According to Lionel Trilling, for example, Mansfield Park has a different moral message from Pride and Prejudice. "Its praise is not for social freedom, but for social stasis. It takes full notice of spiritedness, vivacity, celerity and lightness, but only to reject them as having nothing to do with virtue and happiness, as being, indeed, deterrents to the good life." 4 Others think that the infelicities of the novel and its heroine make it a parody of traditional feminine values and conservative moral thought in general. 5 Here, I shall argue that a path between these two extreme ways of reading the novel is correct. I shall argue, using Alasdair MacIntyre's discussion as a starting [End Page 346] point, that Austen does not cast Fanny as a moral ideal. If Austen is Aristotelian (a common view among philosophers) Fanny cannot be an ideal. And, although I agree with Johnson's view that those who have read the novel as morally conservative are wrong, I do not think that the novel exhibits global skepticism about traditional standards for the beautiful/feminine. Austen condemns the idea that women should be passive dolls who do not think for themselves, but she does not parody the traditional idea that women should be sweet, gentle, and caring. In my view, Fanny's character constitutes a criticism of passivity, and of rigid adherence to moral rules.Alasdair MacIntyre's view is that Austen is an Aristotelian moralist with a Christian slant on the make-up of the virtues. He describes Fanny's character as an ideal of virtue. He argues that Fanny is pretty much lacking in charm just because Austen wanted to focus on the nature of virtue, which charm can obscure and which Fanny is meant to epitomize.For charm is the characteristically modern quality which those who lack or simulate the virtues use to get by in situations of characteristically modern social life... And the charm of an Elizabeth Bennett... may mislead us... Fanny is charmless; she has only the virtues, the genuine virtues to protect her... and when she disobeys her guardian, Sir Thomas Bertram, and refuses marriage to Henry Crawford it can only be because of what constancy requires. In so refusing she places the danger of losing her soul before the reward of gaining what for her would be a whole world. She pursues virtue for the sake of a certain kind of happiness and not for its utility. 6So, MacIntyre thinks that Fanny Price is meant to be a stripped down model of virtue, with constancy being the keystone virtue that she exhibits. "Constancy is crucial in at least two novels, Mansfield Park and Persuasion, in each of which it is a central virtue of the heroine... And without constancy all the other virtues to some degree lose their point" (AV, p. 242).But when constancy is discussed... (shrink)

The Big Fix is, as Greider describes, “the utter folly of allowing a profit-driven industry to name its price, while quietly making over our public-health agenda in its own image”—the theme of the book.

ABSTRACTJulian of Norwich, anchorite and seer, was, according to the twentieth-century mystic poet and monk Thomas Merton, “one of the most wonderful of all Christian voices” and “with Newman the greatest English theologian.” Her Shewings, or Revelations of Divine Love, are an account, meditation, and teaching proceeding from sixteen visions she experienced on a single day in May of 1373. This “Soundproof Room” encounter takes the form of a mild creole of medieval and postmodern English of the sort that (...) in prior works, most notably Paris Views and Foucault in Winter, in the Linnaeus Garden, the author has called “mixed language.” Here also the author takes his cue from Merton’s reputed avowal that “Rather than ‘Sister’, one calls her the ‘Lady Julian’,” by making dialogue a like instance of seeking how to address another.

We are concerned here with two towers. One is a Norman keep in the Galway barony of Kiltartan, some twenty miles from the western seacoast. The second, one of a chain constructed by the British to withstand a Napoleonic invasion, stands facing eastwards towards the Irish sea at the village of Sandycove, a few miles south of Dublin. Yeats's tower at Ballylee—Ballylee Castle as it was grandly termed—and the Martello tower in which Joyce lived in for a few weeks (...) in 1904, the setting upon which Ulysses opens, take on central and symbolic roles in the art of each man and enter also those shorthands of symbols by which we, in our turn, hold the two writers in our imagination. I propose to consider the very different manner in which each man came to accept his identity as an Irish writer. And this in its turn involves some consideration of what for convenience we may term the "matter of Ireland," the body of oral and written Irish literature, and the accumulated symbolic powers of the word "Ireland" itself. If I place their two towers, Ballylee and Martello, as twin emblems at our entrance way, it will at last appear, I trust, that I do so for substantial rather than decorative purposes.

Thomas Jefferson is among the most important and controversial of American political thinkers: his influence (libertarian, democratic, participatory, and agrarian-republican) is still felt today. A prolific writer, Jefferson left 18,000 letters, Notes on the State of Virginia, an Autobiography, and numerous other papers. Joyce Appleby and Terence Ball have selected the most important of these for presentation in the Cambridge Texts series: Jefferson's views on topics such as revolution, self-government, the role of women and African-American and Native Americans (...) emerge to give a fascinating insight into a man who owned slaves, yet advocated the abolition of slavery. The texts are supported by a concise introduction, suggestions for further reading and short biographies of key figures, all providing invaluable assistance to the student encountering the breadth and richness of Jefferson's thought for the first time.

I have three aims in this essay. I want to offer an example of an interdisciplinary historical inquiry combining literary criticism with the relatively new field of critical legal studies. I intend to use this historical inquiry to argue that the ambiguity of literary texts might better be understood in terms of an era’s social contradictions rather than in terms of the inherent qualities of literary language or rhetoric and, conversely, that a text’s ambiguity can help us expose the contradictions (...) masked by an era’s dominant ideology. I try to prove my assertion by applying my method to Herman Melville’s three most famous short works—“Benito Cereno,” “Bartleby, the Scrivener,” and Bill Budd, Sailor—works dealing with the law and lawyers and widely acknowledged as ambiguous.1 I will base my critical inquiry into these stories on Melville’s relationship with his father-in-law, Lemuel Shaw, who, while sitting as the chief justice of the Supreme Judicial Court of Massachusetts from 1830 to 1860, wrote some of the most important opinions in what Roscoe Pound has called “the formative era of American law.”2Before I get started, I should clarify what this study does not entail. By using Shaw and his legal decisions in conjunction with Melville’s fiction, I am not conducting a positivistic influence study. My method will not depend on the positivist assumption that Shaw’s legal opinions can be used to illuminate Melville’s texts only when his direct knowledge of Shaw’s opinions can be proved. Nor will I limit myself to a traditional psychoanalytic reading: my emphasis is on political and social issues, and too often these issues are deflected by translating them into psychological ones. At the same time, I recognize that critics concerned with political and social issues too often neglect questions raised by a writer’s individual situation. I compare Shaw to Melville not to reduce Melville’s politics to psychology but to prevent a political study from neglecting the political implications of psychology, to remind us—as the title of Fredric Jameson’s book The Political Unconscious reminds us—that psychological questions always have political implications. 1.

History, Kern remarks in his introduction, could be written by looking at parliaments, families, or bourgeoisies. Kern chooses rather to focus on the broadest common denominators of historical experience: time and space. Specific understandings of time and space can be identified in any political, artistic, technological, or philosophical practices one may choose to study. This is particularly evident in the period of European history between 1880 and 1918, the age of the airplane, the telephone, and the wireless, of Cubism, cinema, (...) and simultaneous poetry, of Bergson, Einstein, and Joyce, of a war whose dimensions and methods were made possible only through radically new senses of the nature of time and space.

Natural kinds are often contrasted with other kinds of scientific kinds, especially functional kinds, because of a presumed categorical difference in explanatory value: supposedly, natural kinds can ground explanations, while other kinds of kinds cannot. I argue against this view of natural kinds by examining a particular type of explanation—mechanistic explanation—and showing that functional kinds do the same work there as traditionally recognized natural kinds are supposed to do in “standard” scientific explanations. Breaking down this categorical distinction between traditional natural (...) kinds and other kinds of kinds, I argue, delivers two goods: It provides us with a view of natural kindhood that does justice to the epistemic roles of kinds in scientific explanations. And it allows us to solve a problem that HPC theory, currently one of the more popular accounts of natural kindhood, confronts. (shrink)

This work argues for the need to close the gap between the fields of the philosophy of religion and religious studies. Thomas A. Lewis takes up what, in recent years, has often been seen as a fundamental reason for excluding religious ethics and philosophy of religion from religious studies: their explicit normativity. Against this presupposition, Lewis argues that normativity is pervasive--not unique to ethics and philosophy of religion--and therefore not a reason to exclude them from religious studies. He bridges (...) more philosophical and historical subfields by arguing for the importance of history to the philosophy of religion. He considers the future of religious ethics, explaining that the field as whole should learn from the methodological developments associated with recent work in comparative religious ethics and 'comparative religious ethics' should no longer be conceived as a distinct subfield. The concluding chapter engages broader, post-9/11 arguments about the importance of studying religion, arguing that prominent contemporary notions of 'religious literacy' actually hinder our ability to grasp the significance of religion and impact in the world today.

While evolutionary thinking is increasingly becoming popular in fields of investigation outside the biological sciences, it remains unclear how helpful it is there and whether it actually yields good explanations of the phenomena under study. Here we examine the ontology of a recent approach to applying evolutionary thinking outside biology, the generalized Darwinism approach proposed by Geoffrey Hodgson and Thorbjørn Knudsen. We examine the ontology of populations in biology and in GD, and argue that biological evolutionary theory sets ontological criteria (...) that GD fails to meet. We suggest two options to revise the population concept in GD: reformulating the concept in terms of inheritance and reproduction such that it comes to pick out individuals similar to evolving populations, or trying to build an adequate population concept on a principle of differential retention instead of differential reproduction. 1 Introduction2 Generalized Darwinism2.1 What is generalized Darwinism?2.2 Darwinian principles3 The Ontology of Generalized Darwinism: What Are Populations?3.1 The population concept of generalized Darwinism3.2 The population concept in evolutionary theory4 Locating Evolving Systems in Generalized Darwinism5 Conclusion.

Non-epistemic values play important roles in classificatory practice, such that philosophical accounts of kinds and classification should be able to accommodate them. Available accounts fail to do so, however. Our aim is to fill this lacuna by showing how non-epistemic values feature in scientific classification, and how they can be incorporated into a philosophical theory of classification and kinds. To achieve this, we present a novel account of kinds and classification, discuss examples from biological classification where non-epistemic values play decisive (...) roles, and show how this account accommodates the role of non-epistemic values.

Paul Eidelberg surveys the rise of secularism from Socrates to Machiavelli. Hellmut Fritzsche, a physicist, catalogs some famous scientific mistakes. David Grene (Anastaplo's dissertation advisor) looks at Shakespeare's Measure for Measure as "mythological history." Harry V.

Studs Terkel interviews Anastaplo on his encounter with the Illinois bar, and John Van Doren and others contribute a selection of poems. George Anastaplo turned to an academic career when he was denied admission to the bar in 1950 because, on principle, he affirmed the right of revolution and refused to say whether he was a Communist. In this age of academic specialization, Anastaplo's career has been distinguished by a remarkable versatility of thought. Author of five books, including The Artist as Thinker: From Shakespeare to Joyce (Swallow Press, 1983), Human Being and Citizen: Essays on Virtue, Freedom and the Common Good (Swallow Press, 1986), The Constitution of 1787: A Commentary (1989), and The American Moralist: On Law, Ethics, and Government (Ohio University Press, 1992), Anastaplo has also, for the past three decades, produced a steady stream of essays, articles, and papers on subjects from baseball to the Koran, from Socrates to Freud.

Organizational ecology is commonly seen as a Darwinian research program that seeks to explain the diversity of organizational structures, properties and behaviors as the product of selection in past social environments in a similar manner as evolutionary biology seeks to explain the forms, properties and behaviors of organisms as consequences of selection in past natural environments. We argue that this explanatory strategy does not succeed because organizational ecology theory lacks an evolutionary mechanism that could be identified as the principal cause (...) of organizational diversity. The “evolution” of organizational populations by means of selection, which organizational ecologists put forward as the mechanism responsible for the extant diversity of organizational forms, is not evolution in any proper sense, because organizational populations do not have what it takes to participate in evolutionary processes. This implies that organizational ecology is not a Darwinian research program and that it cannot explain organizational diversity. (shrink)

In Civic Liberalism, prominent political theorist Thomas A.

Keith DeRose gives an invalid argument for contextualism in “Assertion, Knowledge, and Context.” In section 2.4, entitled “The Argument for Contextualism,” DeRose makes the following remarks. “The knowledge account of assertion provides a powerful argument for contextualism: If the standards for when one is in a position to warrantedly assert that P are the same as those that comprise a truth-condition for ‘I know P,’ then if the former vary with context, so do the latter. In short: The knowledge account (...) of assertion together with the context-sensitivity of assertability yields contextualism about knowledge”. (shrink)

In this target article we question the assumption that perception is divided into separate domains of vision, hearing, touch, taste, and smell. We review implications of this assumption for theories of perception and for our understanding of ambient energy arrays (e.g., the optic and acoustic arrays) that are available to perceptual systems. We analyze three hypotheses about relations between ambient arrays and physical reality: (1) that there is an ambiguous relation between ambient energy arrays and physical reality, (2) that there (...) is a unique relation between individual energy arrays and physical reality, and (3) that there is a redundant but unambiguous relation, within or across arrays, between energy arrays and physical reality. This is followed by a review of the physics of motion, focusing on the existence and status of referents for physical motion. Our review indicates that it is not possible, in principle, for there to be a unique relation between physical motion and the structure of individual energy arrays. We argue that physical motion relative to different referents is specified only in the global array, which consists of higher-order relations across different forms of energy. The existence of specificity in the global array is consistent with the idea of direct perception, and so poses a challenge to traditional, inference-based theories of perception and cognition. However, it also presents a challenge to much of the ecological approach to perception and action, which has accepted the assumption of separate senses. (shrink)

Business schools play an instrumental role in laying the foundations for ethical behavior and socially responsible actions in the business community. Drawing on social learning and identity theories and using data collected from undergraduate business students, we found that ethical climate was a significant predictor of unethical behavior, such that students with positive perceptions about their business school’s ethical climate were more likely to refrain from unethical behaviors. Moreover, we found that high moral and institutional identities strengthened the effect of (...) ethical climate on unethical behavior. In addition to novel theoretical contributions to the business ethics and socio-psychology literature, this study offers practical pathways through which business schools can nurture and instill the values and behaviors that ultimately help shape positive organizational ethics. Directions for future research are provided. (shrink)

In Plato’s Gorgias, Socrates says to Callicles that “your love of the people, existing in your soul, stands against me, but if we closely examine these same matters often and in a better way, you will be persuaded” (513c7–d1).

There is an interesting parallel between two debates in different domains of contemporary analytic philosophy. One is the endurantism– perdurantism, or three-dimensionalism vs. four-dimensionalism, debate in analytic metaphysics. The other is the debate on the species problem in philosophy of biology. In this paper I attempt to cross-fertilize these debates with the aim of exploiting some of the potential that the two debates have to advance each other. I address two issues. First, I explore what the case of species implies (...) regarding the feasibility of particular positions in the endurantism– perdurantism debate. I argue that the case of species casts doubt on the recent claim that three-dimensionalism and four-dimensionalism are equivalent descriptions of the same underlying reality. Second, and conversely, I examine whether the metaphysical worry about three-dimensionalism and four-dimensionalism can help us to better understand the nature of biological species. I show that analyzing the thesis that species are individuals against the background of the endurantism– perdurantism debate allows us to explicate two different ways in which this thesis can be interpreted.
