The autobiography of one of the most versatile of American scientists of his generation, the first to be trained largely in his own country. A scientific generalist, Morse has made significant contributions to atomic physics, quantum mechanics, plasma physics, astrophysics, acoustics, machine computation, and operations research. Philip Morse has surely been one of the most versatile of American scientists of his generation, the first to be trained largely in his own country. A scientific generalist, he has made (...) significant contributions to atomic physics, quantum mechanics, plasma physics, astrophysics, acoustics, machine computation, and operations research. His life-long commitment to teaching, through his authorship of a series if standard-setting textbooks and through his personal guidance of unnumbered individual students, has extended this scope to include thermodynamics, statistical mechanics, and the methods of theoretical physics as well. Moreover, as this autobiography relates at a fast-moving pace, Morse has also been involved in the high-pressure concerns of war research, scientific administration and consultation, policy formation, the education of key groups and wider publics beyond the classroom, and the real-world utilization of scientific techniques and discoveries. For all these accomplishments, Morse writes that his experience as a scientist and as a participant in the affairs of his time "has been at the second, rather than at the top, level." It may be that this circumstance of being neat, rather than at, the top makes this autobiography more, rather than less, relevant to other and younger scientists, to those considering a life in science, and to general readers curious as to what such a life is really like. Only a miniscule few reach, say. Einsteinian levels, and their lives and work tend to be unique unto themselves; what Morse reports is truer to the experience of the great majority of the members of the scientific community. While his actual accomplishments, his range, and his eminence certainly far exceed those of a "typical" scientist, they do so more in degree than in kind. Morse's style is straightforward and nontechnical, direct, and personal. Some of the lighter moments and revealingly human incidents of his experience are recorded along with the problems and breakthroughs in the near-private world of pure science and the public worlds of policy, high-level consultation, and practical applications.

When Philip Morse was promoted to Professor Emeritus of Physics at M.I.T. in 1969, he already had behind him at least three full professional careers--in Quantum physics, in acoustics, and in what Julius Stratton calls "the reduction of theory to numerically useful results," a general field of which Morse was a founder and for which no good term yet exists, that includes operations research, machine computation, and systems analysis. This volume contains papers in all these fields, written (...) by Professor Morse's students and colleagues. By their presence here, they gratefully testify to the influence that Philip Morse has had on their work and, in many cases, on their lives. (shrink)

Christian ethicist Nancy Duff has suggested that an apocalyptic hearing of the gospel elicits a parabolic understanding of the Christian moral life. How might the theological basis and rationale of this claim be elaborated? What is it about human life funded by the gospel of God’s apocalypse in Jesus Christ that makes ‘parable’ an apt description of the quality of its action? And how might these notions be elaborated to enrich our understanding of responsible moral action more generally? This article (...) explores these questions by way of a running conversation with the work of J. Louis Martyn, Christopher Morse and Paul Ricoeur. It concludes by showing the salience of these themes in relation to Bonhoeffer’s later reflections upon the distinctive quality of Christian life in the wreckage of Christendom. Overall, the solid currency of a parabolic construal of the character of Christian moral action for the present pursuit of theological ethics is recommended. (shrink)

Mountaineering is a dangerous activity. For many mountaineers, part of its very attraction is the risk, the thrill of danger. Yet mountaineers are often regarded as reckless or even irresponsible for risking their lives. In this paper, we offer a defence of risk-taking in mountaineering. Our discussion is organised around the fact that mountaineers and non-mountaineers often disagree about how risky mountaineering really is. We hope to cast some light on the nature of this disagreement – and to argue that (...) mountaineering may actually be worthwhile because of the risks it involves. Section 1 introduces the disagreement and, in doing so, separates out several different notions of risk. Sections 2–4 then consider some explanations of the disagreement, showing how a variety of phenomena can skew people's risk judgements. Section 5 then surveys some recent statistics, to see whether these illuminate how risky mountaineering is. In light of these considerations, however, we suggest that the disagreement is best framed not simply in terms of how risky mountaineering is but whether the risks it does involve are justified. The remainder of the paper, sections 6–9, argues that risk-taking in mountaineering often is justified – and, moreover, that mountaineering can itself be justified by and because of the risks it involves.

In the introductory remarks to his Mulierum Virtutes, Plutarch notes the value of comparisons for establishing the diverse manifestations of the same virtue: ‘Achilles was brave in one way, Ajax in another; and the intelligence of Odysseus differed from that of Nestor, nor were Cato and Agesilaus just in the same way, nor was Irene loving of her husband () as Alcestis was, nor Cornelia high-minded in the manner of Olympias’. All the examples are well known, and quite apposite, except (...) for Irene (). Who is this paragon of wifely love? A search through encyclopedias and mythological handbooks proves fruitless. Wyttenbach in his note ad loc. suggested the courtesan friend of a minor Ptolemy killed at Ephesus, yet this extremely obscure figure hardly merits mention in the same breath with Alcestis. The name must be corrupt. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Historical Commentary on Arrian’s History of Alexander. Vol. II. Commentary on Books IV–VPhilip A. StadterBosworth, A. B. A Historical Commentary on Arrian’s History of Alexander. Vol. II. Commentary on Books IV–V. Oxford: Clarendon Press, 1995.In books 1–3, Arrian’s Alexander rushed from the Hellespont to Babylon, Susa, and Persepolis. In books IV and V the story changes: Alexander finds himself on the frontier, and beyond. No longer is (...) he confronting the enormous armies of the Persian king in set battles, but pushing beyond the frontiers of empire, seizing impregnable heights, and most important, struggling with his own Macedonians while defining himself.Bosworth, continuing his commentary after a fifteen-year interval, brings an exceptional background of historical, source critical, and literary studies. B. notes that his evaluation is “perhaps more sympathetic” than in his first volume, in part because the quality of the work “improves as it progresses” (v). The thoroughness [End Page 140] of the discussion (360 pages on the two books) is justified by the importance and complexity of the material. The reader is well served by an excellent subject index, a Greek index, ten maps, and four figures. An appendix on Nearchus suggests that that author may have reported much more than the journey from the Indus to the Persian Gulf found in the Indike, and may be a significant source for Arrian in the last four books of the Alexander history. Like the first volume, the commentary has Greek lemmata, translated only when there is a specific difficulty, but even Greekless readers can use it with the help of Brunt’s new Loeb text.Although the commentary deals frequently with textual questions, it focuses on elucidating the historical, geographical, stylistic, and interpretative problems of the text. B. ably notes the constant verbal reminiscences of Herodotus, Thucydides, and Xenophon, especially in the more elaborate passages, e.g., the speeches at the Hyphasis. Still more are undoubtedly to be found, such as the echo of Thucydides (1.110.1, 3.112.8, 87.87.6) in 5.27.6, ¹l¼goi ¨k poll©n. His elucidation of Arrian’s use of Megasthenes, Nearchus, and Eratosthenes in the digressions at the beginning of book 5 is a model of clarity and precision. Here as elsewhere he stresses Arrian’s purposeful blending of his sources: e.g., on 5.6.3–8: “It is an elaborately contrived passage, and the source material is carefully selected to fit the scheme of the argument. Arrian is not merely rewriting a passage of Eratosthenes.” Throughout, his comments on sources are precise and thoughtful.B.’s notes follow wherever the text leads, but he devotes special attention to the major focuses of Arrian’s attention: the great digression on Alexander’s orientalism, the murder of Cleitus, proskunesis, and the page’s conspiracy (4.7.4–14.4 5 45–101), the march to the Indus, with the siege of Massaga and the capture of Aornus (4.22.3–30.9 5 141–96), the series of digressions which begin book 5, (5.1.1–8.1 5 197–259), the battle on the Hydaspes against Porus (5.8.4–19.4 5 262–311), and the mutiny on the Hyphasis (5.24.8–29.5 5 337–60).Bosworth’s commentary on book 5 encompasses the multiple levels of the narrative: the reworking of Eratosthenes, Megasthenes, and Nearchus in the preliminary section; the topographical and tactical problems of the battle with Porus, and the rhetorical and stylistic subtleties of the debate at the Hyphasis. Throughout the book, Arrian shows Alexander going beyond his predecessors. By crossing the Indus he passes the limits of the Persian Empire. At Nysa he surpasses the mythical conquests of Dionysus (5.2.1). The digression on the Indus bridges recalls the bridges (and defeats) of Xerxes and Darius, as well as Roman imperial engineering (5.7.1–2). The crossing of the Hydaspes and great battle contrast with Cyrus’ disastrous battle with the Massagetae in Herodotus 1.204–14 (cf. 5.4.5). The description of the river systems of the Punjab (5.4.1–2) evokes Herodotus’ account... (shrink)

Scholarly use of the label “school” to describe groups of philosophers has sometimes led to a neglect of the ways in which such gatherings of philosophers could function as unofficial associations of recognizable types. Concerns to distance supposedly “secular” philosophers from any “religious” connection have fed into this image of the philosophical “school,” diverting attention away from other important dimensions of associative life among philosophers and other literate professionals, including involvement in honours for the gods and in commensal activities. Epigraphic (...) evidence helps to elucidate the broader associative context. The fact that some philosophers formed associations has implications for adjacent fields, such as Christian origins, where there is a tendency to ask whether groups of Jesus followers were socially analogous to a Judean synagogue, an association, or a philosophical school, as though these were distinct options rather than overlapping social phenomena. Such associations of relatively literate people were among the few in antiquity that can also be described using the scholarly category of “reading communities.”. (shrink)

Abstractionism, which is a development of Frege's original Logicism, is a recent and much debated position in the philosophy of mathematics. This volume contains 16 original papers by leading scholars on the philosophical and mathematical aspects of Abstractionism. After an extensive editors' introduction to the topic of abstractionism, the volume is split into 4 sections. The contributions within these sections explore the semantics and meta-ontology of Abstractionism, abstractionist epistemology, the mathematics of Abstractionis, and finally, Frege's application constraint within an abstractionist (...) setting.

Fodor & Pylyshyn (1981) criticize J. J. Gibson's ecological account of perception for failing to address what I call the 'correlation problem' in visual perception. That is, they charge that Gibson cannot explain how perceivers learn to correlate detectable properties of the light with perceptible properties of the environment. Furthermore, they identify the correlation problem as a crucial issue for any theory of visual perception, what I call a 'primary problem'—i.e. a problem which plays a definitive role in establishing the (...) concerns of a particular scientific research program. If they are correct, Gibson's failure to resolve this problem would cast considerable doubt upon his ecological approach to perception. In response, I argue that both Fodor & Pylyshyn's problem itself and their proposed inferential solution embody a significant mistake which needs to be eliminated from our thinking about visual perception. As part of my response, I also suggest a Gibsonian alternative to Fodor & Pylyshyn's primary problem formulation. (shrink)

Assisted dying (AD) has not been legalized despite a number of presentations to parliament. It is necessary for doctors who support AD to justify themselves in the context of repeated legislative failure. This article describes the author's personal approach to the problem, one that prioritizes respect for autonomy above legal or societal objections. It is argued that for debilitated patients, the preservation of autonomy depends on a doctor's empathy and willingness to advocate. This sequence can be interrupted by externally and (...) internally imposed barriers. External factors include indiscriminate respect for the law and society's institutions, an inaccurate perception of the balance of risks to society and insufficient compensation for the dying person's inability to mount a sustained challenge. Internal brakes to advocacy such as elevation of personal morality above the needs of patients, attenuation of the therapeutic relationship in cases of moral complexity and the temptation to abdicate the role of physician are also explored. It is concluded that if AD could in theory be of benefit to a patient, but cannot be achieved due to its illegality, doctors have a duty to actively represent their demands as they would for other forms of treatment.

In lieu of an abstract, here is a brief excerpt of the content:Brief Mention The Classicist’s ThirstP. A. S.( Od.11.582–92)These are some of the first lines I read of Greek poetry, thanks to Schoder’s Homeric Greek,and they are part of the reason I became a classicist. Their simplicity, directness, and clear statement of a man’s desperate longing for what is necessary and beautiful stirred my unformed youth and incited me to master as best I could this delightful impossible language. Forever (...) eager, forever denied, Tantalus now strikes me as the image of the scholar always hoping to reach and make his own the truth, always finding it receding from his lips, or scribbling pen.In each century, ever since Petrarch rediscovered Cicero’s letters and Livy’s decades and thought he had found kindred spirits, with whom he could converse directly over the ages, scholars have sought for methods of establishing a closer tie to the classical past and modes of relating it to their own world. Every century has built on what has gone before, while criticizing previous work as inadequate or wrongheaded. Petrarch began the search for manuscripts, reassembling the decades of Livy, and inspiring Boccaccio and later humanists in a chase for treasures that continued into the sixteenth century. But bare manuscripts were not enough: soon the need for a renewed study of grammar and diction became apparent, for the collation and emendation of texts, for translation into the vernacular.Let Poliziano stand for many: he brought to the work of emendation and interpretation of classical Latin texts a knowledge of Greek remarkable in his day, a precise familiarity with a wide range of authors and their commentators, and the technique of evaluating manuscripts by [End Page 143]their age. He would hunt out and note the readings of the earliest codices available—he found many in Florence, assembled by previous scholars—and emend the vulgate tradition, often using Greek texts to correct the Latin. With these tools he was able to make an outstanding contribution to the text and interpretation of authors. Each short essay of the Miscellaneorum centuria primaand the unfinished Centuria secundais cut like a small jewel, the ingenuity and insight of each facet flashing the brilliance of his method. How often he seems to have escaped Tantalus’ fate, and sipped the water, tasted that delicious fruit.Yet important as his work was, at a distance of time the elusive truth recedes, and must be sought all over again. The oldest manuscripts are not necessarily the best, stemmata can play strange tricks, contamination can confuse traditions, anonymous correctors are revealed as identifiable scholars. Methods are refined, new techniques tried, terminology clarified. Now Poliziano’s marvelous command of the Latin vocabulary is available to the undergraduate who troubles to do a word search on the PHI CD-ROM, though not with the linguistic skill or knowledge of context to use it well. Microfilm, copying machines, and air travel allow inspection of manuscripts scattered throughout the world. Students use texts annotated with the learning of five hundred years, and have at their fingertips information even a Poliziano could not know. Yet somehow our thirst is still there, our hunger not satisfied. The sense of the texts, the events and emotions of history, the culture of which they are a part, their meaning to our own lives, are still elusive.Poliziano’s methods have not relieved our thirst, nor have those of Bentley or Mommsen, of Wilamowitz or Gildersleeve, though they have brought us closer to understanding the ancient texts and the world that created them, and have given us a taste of that world, those people. Their work has brought us where we are today. The Estienne motto, found on the cover of the summer issues of the Journal,is apposite: Noli altum sapere. 1Some of the old limbs that did not bear fruit are pruned away and new ones grafted on, but the new depend on the vigor of the old trunk.Each scholar, each generation of scholars, is condemned—or privileged—to repeat the experience of searching for a better method of understanding, of stretching once more toward the receding water.This Journalhas...

This paper is underpinned by an epistemological question: What are the types and ways of knowing that can be entailed in reflective leadership in its fullest sense? The question is explored through a mapping exercise which outlines a geography of reflective leadership in terms of three variables: type of knowledge, problem focus, and mode of learning (incorporating the notion of embodied learning). Particular attention is given to recognising within the terrain of reflective leadership the epistemic credentials of spiritual learning and (...) experiential awareness of spirituality.

W.V.O.Quine’s doctrine of referential inscrutability (RI) is the thesis that, first, linguistic reference must always be determined relative to an interpretation of the discourse and, second, that the empirical evidence always underdetermines our choice of interpretation--at least in principle. Although this thesis is a central result of Quine’s theory of language, it was long unclear just how much force RI actually carried. At best, Quine’s discussions provided localized examples of RI (e.g., ‘gavagai’), supplemented merely by arguments for the (in principle) (...) constructability of more general referentially divergent manuals. In defense of Quine, Gerald Massey provides a method for generating large-scale referentially divergent manuals for a complex language. I argue that, while Massey’s rival manuals do meet Quine’s translational criteria, they are demonstrably inferior to their commonsensical “homophonic” competitor. This result provides a clear indication of seminal deficiencies in Quine’s behaviorial approach to the theory of language. Next I argue that Quine’s acceptance of standard assumptions about the nature of perception strongly influences the shape of his semantical theory. Finally, I suggest how an alternative to the standard account of perception might provide grounds for a more adequate understanding of language. (shrink)

Many commentators propose that Hume thinks that we are not or should not be motivated to perform naturally virtuous actions from moral sentiments if we want our actions to be genuinely virtuous. It is this proposal with which I take issue in this article, arguing that Hume fully incorporates the moral sentiments into his understanding of how human beings act when it comes to the natural virtues and that he does not see the moral sentiments as a problematic kind of (...) motivation that threatens or weakens the virtuous status of the action.

In this paper, we present the results of two surveys that investigate subjects’ judgments about what can be known or justifiably believed about lottery outcomes on the basis of statistical evidence, testimonial evidence, and “mixed” evidence, while considering possible anchoring and priming effects.

We conclude by summarizing the main findings, pointing to future research, and comparing our findings to (...) recent studies by Turri and Friedman. (shrink)

This paper raises and then discusses a puzzle concerning the ontological commitments of mathematical principles. The main focus here is Hume's Principle—a statement that, embedded in second-order logic, allows for a deduction of the second-order Peano axioms. The puzzle aims to put pressure on so-called epistemic rejectionism, a position that rejects the analytic status of Hume's Principle. The upshot will be to elicit a new and very basic disagreement between epistemic rejectionism and the neo-Fregeans, defenders of the analytic status of (...) Hume's Principle, which will provide a new angle from which properly to assess and re-evaluate the current debate. (shrink)

Characterizing how activity in the central and autonomic nervous systems corresponds to distinct emotional states is one of the central goals of affective neuroscience. Despite the ease with which individuals label their own experiences, identifying specific autonomic and neural markers of emotions remains a challenge. Here we explore how multivariate pattern classification approaches offer an advantageous framework for identifying emotion-specific biomarkers and for testing predictions of theoretical models of emotion. Based on initial studies using multivariate pattern classification, we suggest that (...) central and autonomic nervous system activity can be reliably decoded into distinct emotional states. Finally, we consider future directions in applying pattern classification to understand the nature of emotion in the nervous system. (shrink)

A naturalistic account of self-consciousness is developed within a general framework in which thought contents are structured by concepts but conceptual content need not be exhausted at the level of reference. To motivate the first feature of this framework, possible-worlds- and property-based theories of thought content, which eschew structure, are criticized for overestimating and/or underestimating the attitude stock of ordinary agents. To motivate the second feature, it is argued that neo-Russellian and neo-Fregean accounts, which incorporate structure but differ on the (...) semantic classification of psychological modes of presentation, are more or less on a par with respect to standard parameters of evaluation . Though non-notational differences between these accounts remain, these differences add up to less than is commonly supposed. ;Neo-Russellians and neo-Fregeans agree on the explanatory relevance of conceptual modes of presentation, understood as reference-sustaining functional mechanisms; what they disagree about is whether those modes contribute to the content of a concept. Once the semantic dispute is set aside, questions about the nature of these mechanisms come to the fore. In the case of the self concept, what appears to distinguish this concept from coreferring items in an agent's conceptual repertoire is its privileged relation to inputs from internal monitoring systems, on one side, and outputs in control systems, on the other. Self-consciousness emerges as an atomistic conceptual capacity, sustained by both interoceptual mechanisms and agentive ones. (shrink)

Abstract In this essay, a new approach for the ethical study of emerging technology ethics will be presented, called anticipatory technology ethics (ATE). The ethics of emerging technology is the study of ethical issues at the R&D and introduction stage of technology development through anticipation of possible future devices, applications, and social consequences. I will argue that a major problem for its development is the problem of uncertainty, which can only be overcome through methodologically sound forecasting and futures studies. I (...) will then consider three contemporary approaches to the ethics of emerging technologies that use forecasting: ethical technology assessment, the techno-ethical scenarios approach and the ETICA approach, and I considered their strengths and weaknesses. Based on this critical study, I then present my own approach: ATE. ATE is a conceptually and methodologically rich approach for the ethical analysis of emerging technologies that incorporates a large variety of ethical principles, issues, objects and levels of analysis, and research aims. It is ready to be applied to contemporary and future emerging technologies. Content Type Journal Article Category Original Paper Pages 1-13 DOI 10.1007/s11569-012-0141-7 Authors Philip A. E.

Singing is universal, and understanding sung words is thought to be important for many listeners’ enjoyment of vocal and choral music. However, this is not a trivial task, and sung text intelligibility is probably affected by many factors. A survey of musicians was undertaken to identify the factors believed to have most impact on intelligibility, and to assess the importance of understanding sung words in familiar and unfamiliar languages. A total of 143 professional and amateur musicians, including singers, singing teachers, (...) and regular listeners to vocal music, provided 394 statements yielding 851 references to one or more of 43 discrete factors in four categories: performer-related, listener-related, environment-related and words/music-related. The factors mentioned most frequently in each of the four categories were, respectively: diction; hearing ability; acoustic; and genre. In more than a third of references, the extent to which sung text is intelligible was attributed to the performer. Over 60% of respondents rated the ability to understand words in familiar languages as “very important,” but only 17% when the text was in an unfamiliar language. Professional musicians (47% of the sample) rated the importance of understanding in both familiar and unfamiliar languages significantly higher than amateurs but listed fewer factors overall and fewer listener-related factors. The more important the respondents rated understanding, the more performer-related and environment-related factors they tended to list. There were no significant differences between the responses of those who teach singing and those who do not. Enhancing sung text intelligibility is thus perceived to be within the singer’s control, at least to some extent, but there are also many factors outside their control. Empirical research is needed to explore some of these factors in greater depth, and has the potential to inform pedagogy for singers, composers, and choral directors. (shrink)

Situationists contend that virtue ethics is empirically inadequate. However, it is my contention that there is much confusion over what “empirical adequacy” or “empirical inadequacy” actually means in this context. My aim in this paper is to clarify the meanings of empirical adequacy in order to see to what extent virtue ethics might fail to meet this standard. I argue that the situationists frequently misconstrue the empirical commitments of virtue ethics. More importantly, depending on what we mean by empirical adequacy, (...) either virtue ethics has no need to be empirically adequate or where it does have such a need, the psychological evidence fails to show that it is empirically inadequate. An additional contribution the paper intends to make is to provide a more detailed discussion of the explanatory nature of virtue ethics. (shrink)

The notion of risk plays a central role in economics, finance, health, psychology, law and elsewhere, and is prevalent in managing challenges and resources in day-to-day life. In recent work, Duncan Pritchard (2015, 2016) has argued against the orthodox probabilistic conception of risk on which the risk of a hypothetical scenario is determined by how probable it is, and in favour of a modal conception on which the risk of a hypothetical scenario is determined by how modally close it is. (...) In this article, we use Pritchard’s discussion as a springboard for a more wide-ranging discussion of the notion of risk. We introduce three different conceptions of risk: the standard probabilistic conception, Pritchard’s modal conception, and a normalcy conception that is new (though it has some precursors in the psychological literature on risk perception). Ultimately, we argue that the modal conception is ill-suited to the roles that a notion of risk is required to play and explore the prospects for a form of pluralism about risk, embracing both the probabilistic and the normalcy conceptions.

This paper discusses Michael Dummett’s criticism of the Neo-Fregean concep- tion of the context principle. I will present four arguments by Dummett that purport to show that the context principle is incompatible with platonism. I discuss and ultimately reject each argument.

I argue that this tension does (...) give rise to a legitimate concern, yet it does not affect the Neo-Fregean conception of the context principle. (shrink)

In this article, I explore a Bayesian approach to avalanche decision-making. I motivate this perspective by highlighting a version of the base-rate fallacy and show that a similar pattern applies to decision-making in avalanche-terrain. I then draw out three theoretical lessons from adopting a Bayesian approach and discuss these lessons critically. Lastly, I highlight a number of challenges for avalanche educators when incorporating the Bayesian perspective in their curriculum.

In recent years, interest has increased in regenerative practices as a strategy for transforming food systems and solving major environmental problems such as biodiversity loss and climate change. However, debates persist regarding these practices and how they ought to be defined. This paper presents a framework for exploring the regenerative potential of food systems, focusing on how food systems activities and technologies are organized rather than the specific technologies or practices being employed. The paper begins with a brief review of (...) debates over sustainable food systems and the varying ways that regenerative food systems have been defined and theorized. Then, it provides the theoretical backing of the framework—the conservation of change principle—which is an interpretation of the laws of thermodynamics and theories of adaptive change as relevant to the regenerative capacity of living systems. Next, the paper introduces the framework itself, which comprises two independent but intersecting dimensions of food systems organization: resource diversity and livelihood flexibility. These two dimensions result in four archetypical regimes for food systems: degenerative, regenerative, impoverished, and coerced. The paper defines each and offers real-world examples. Finally, the paper concludes with a discussion of pathways for transforming food systems and opportunities for additional research. (shrink)

Research has shown that feelings of self-disgust may have a functional role in the genesis of depression by partially mediating the cross-sectional relationship between dysfunctional thoughts and depressive symptoms. However, there are many outstanding issues regarding these hypothesised associations. First, it is not yet clear whether self-disgust is a temporal antecedent, concomitant, or consequence of depressive experience. Second, it is not known whether the hypothesised mediation sequence is valid over time. Third, the relative contribution of disgust towards different aspects of (...) the self has not yet been examined. In the present longitudinal study, participants completed measures of dysfunctional cognitions, self-disgust and depressive symptoms at baseline, and at six and 12-month follow-ups. Analysis showed that self-disgust is best considered as antecedent to depressive symptoms; the hypothesised mediation model was partially supported, but is too simplistic; and disgust towards physical aspects of the self, rather than behaviour, was more important as a temporal predictor of depressive symptoms. The current results help elucidate the role of self-disgust as an antecedent of depressive experience. (shrink)

Next SectionIt is commonly proposed that artifacts cannot be understood without reference to human intentions. This fact, I contend, has relevance to the use of artifacts in intentional action. I argue that because artifacts have intentions embedded into them antecedently, when we use artifacts we are sometimes compelled to intend descriptions of our actions that we might, for various reasons, be inclined to believe that we do not intend. I focus this argument to a specific set of artifacts, namely, medical (...) devices, before considering an extended application to emergency contraceptive devices. Although there is some debate about whether emergency contraception has an abortifacient effect, I argue that if there is an abortifacient effect, then the effect cannot normally be a side effect of one’s action.

Essential to the doctrine of double effect is the idea that agents are prohibited from intending evil as a means to a good end. I argue in this paper that some recent accounts of intention from proponents of double effect cannot sustain this prohibition on harmful means. I outline two ways to gerrymander intention that mark these accounts. First, intention is construed in such a way that an agent intends only those states of affairs that she cares about or finds (...) motivating for their own sake. Second, intention is construed in such a way that what counts as intended is determined sufficiently by the agent’s beliefs. (shrink)
