The received view is that Kant denies all moral luck. But I show how Kant affirms constitutive moral luck in passages concerning radical evil from Religion within the Boundaries of Mere Reason. First, I explicate Kant’s claims about radical evil. It is a morally evil disposition that all human beings have necessarily, at least for the first part of their lives, and for which they are blameworthy. Second, since these properties about radical evil appear to contradict Kant’s even more famous (...) claims about imputation, ‘ought implies can’, and free will, I unpack Henry Allison’s proof of radical evil and show how it is consistent with interpretations of Kant’s broader views about morality. Third, I define and illustrate the category of constitutive moral luck and argue that Kant embraces the existence of constitutive moral luck given Allison-style interpretations of radical evil. This provides a reason for philosophers to reject the received view, and it creates an occasion for Kantians and Kant scholars to check their reasons if they deny moral luck. (shrink)

The term “medium independence” has different meanings. One sense maps onto “abstract-as-abstracta” descriptions while the other maps onto “abstract-as-omission” descriptions. Both senses have been deployed when it comes to understanding the nature of physical computation. However, because medium independence is a polysemic term, the sense being used should be clearly stated. If the sense is not clearly stated, then those who wish to engage in debates regarding medium independence and physical computation run the risk of conflating different but related issues (...) which can have consequences when it comes to thinking about physical computation across contexts.

Because Paul has proven difficult to understand, the interpreter must pay careful attention to the language, the rhetorical structure, and the context if unnecessary difficulties are to be avoided.

It is widely thought that there are limits to how things can perceptually appear to us. For instance, nothing can appear both square and circular, or both pure red and pure blue. Adam Pautz has dubbed such constraints “laws of appearance.” But if the laws of appearance obtain, then what explains them? Here I examine the prospects for an empirical explanation of the laws of appearance. First, I challenge extant empirical explanations that appeal purely to the format of perceptual representation. (...) I then develop a hybrid approach, on which the laws are explained not merely by format, but by two further factors: ecological constraints imposed by our environments, and computational constraints embodied by our perceptual systems. While the hybrid approach implies that the laws of appearance are contingent, I argue that this implication is empirically defensible, since even some of the most intuitively compelling laws have real-world counterexamples.

This paper proposes that managers add an attention to virtues and vices of human character as a full complement to moral reasoning according to a deontological focus on obligations to act and a teleological focus on consequences (a balanced tripartite approach). Even if the criticisms of virtue ethics cloud its use as a mononomic normative theory of justification, they do not refute the substantial benefits of applying a human character perspective – when done so in conjunction with also-imperfect act-oriented perspectives. (...) An interactive tripartite approach is superior for meeting the complex requirements of an applied ethic. To illustrate how deficiencies of a "strong" virtue ethics formulation can be overcome by a balanced tripartite approach, this paper compares normative leadership paradigms (each based on a combination of virtue, deontology, or consequentialist perspectives) and the dangers inherent in each. The preferred paradigm is servant leadership, grounded in a tripartite ethic. Effective application of such an ethics approach in contemporary organizations requires further empirical research to develop a greater understanding of the moral language actually used. Meeting this challenge will allow academics better to assist practicing managers lead moral development and moral reasoning efforts. (shrink)

The experience of having to suffer debilitating pain is far too common in the United States, and many patients continue to be inadequately treated by their doctors. Although many physicians freely admit that their pain management practices may have been somewhat lacking, many more express concern that the prescribing of heightened levels of opioid analgesics may result in closer regulatory scrutiny, criminal investigation, or even criminal prosecution.Although several researchers have examined the regulatory environment and the threat of sanction or harm (...) it poses to physicians and patients, few have examined the likelihood of investigation or prosecution stemming from the aggressive use of opioids in physician-directed pain management. Accordingly, in an effort to assess whether the fear of prosecution is realistic and, if so, what factors contribute to its likelihood, we surveyed chief prosecutors in four states about their knowledge, opinions, and attitudes concerning opioids and the prosecution of physicians stemming from the treatment of patients who were either terminally ill or suffering from chronic noncancer pain.

The terms `endurance' and `perdurance' are commonly thought to denote distinct ways for an object to persist, but it is surprisingly hard to say what these are. The common approach, defining them in terms of temporal parts, is mistaken, because it does not lead to two coherent philosophical alternatives: endurance so understood becomes conceptually incoherent, while perdurance becomes not just true but a conceptual truth. Instead, we propose a different way to articulate the distinction, in terms of identity rather than (...) temporal parts: an object endures if its identity is determined at every moment at which it exists. We make precise what it means for the identity of an object to be determined at a moment. We also discuss what role the endurance / perdurance distinction, so understood, should play in the debates about time, material objects and personal identity. (shrink)

Philosophers agree that scientific explanations aim to produce understanding, and that good ones succeed in this aim. But few seriously consider what understanding is, or what the cues are when we have it. If it is a psychological state or process, describing its specific nature is the job of psychological theorizing. This article examines the role of understanding in scientific explanation. It warns that the seductive, phenomenological sense of understanding is often, but mistakenly, viewed as a cue of genuine understanding. (...) The article closes with a discussion of several new paths of research that tie the psychology of scientific explanation to cognate notions of learning, testimony, and understanding. (shrink)

This article outlines an epistemological perspective to understand the organism as a temporally changing whole. To analyze the mental faculties involved, the organism’s development and persisting existence is differentiated into four interdependent aspects: descent, future existence, persistent species, and environmentally adapted physical appearance. It is outlined that these aspects are recognized by comparative memory, concept-guided anticipation, conceptual thinking, and sensory perception, respectively. Furthermore, it is pointed out that these aspects correspond to the famous four Aristotelian “causes” or principles of explanation. (...) The descent of an organism corresponds to Aristotle’s efficient principle (“where does it come from?”), its future existence to the final principle (“what is if for?”), its physical structure to the material principle (“out of what is it?”) and its persistent species to the formal principle (“what is it?”). Aristotle regarded the unity of the efficient, formal and final principle as the ontological cause of the organism and called it the “soul” (psyche), while the material principle can be understood to represent its “body” (soma). I suggest that Aristotle’s “soul” corresponds to three of the four mental faculties required for cognition of a self-maintaining organism. I argue that in a Kantian perspective, the Aristotelian “soul” represents the condition for recognizing an organism at all. Therefore, the Aristotelian principle of life becomes intelligible and even empirically observable through the inner sense. In summary, I suggest that the four aspects of the organism described here can be viewed as the general, epistemological and ontological principle of the organism, the Bio-Logos. (shrink)

One proposed explanation for a particular kind of temporal preference lies in a disparity between the emotional intensity of memory compared to anticipation. According to the memory/anticipation disparity explanation, the utility of anticipation of a particular event if that event is future, whether positive or negative, is greater than the utility of retrospection of that same event if it is past, whether positive or negative, and consequently, overall utility is maximised when we prefer negative events to be located in the (...) past rather than the future, and positive ones in the future rather than the past. To have this preference is to be (at least apparently) future biased. If this explanation is correct, it would tend to confer rational justification upon these preferences. This paper empirically investigates this explanation. Our results suggest that, at most, this explanation might be a partial one of some people’s preferences some of the time, rather than a general explanation of future bias. In turn, this lends some indirect support to a competing explanation that appeals to temporal asymmetries in emotion and attention. Since that explanation would arguably tend not to confer rational justification upon (apparently) future-biased preferences, we argue that our findings provide some reason to be sceptical that these preferences are, in general, rationally justified.

We investigate the causal manipulability hypothesis, according to which what partly explains (a) why people tend to prefer negative events to be in their further future rather than their nearer future and positive events to be in their nearer future rather than their further future and (b) why people tend to prefer that negative events be located in their past not their future and that positive events be located in their future not their past, is that people tend to discount (...) the value of events they are less able causally to manipulate. If people discount the value of events they are less able to causally manipulate, then since often temporally nearer future events are more causally manipulable than further ones, and since future events are manipulable whereas past ones aren’t, this could explain both (a) and (b). In turn, if the causal manipulability hypothesis is correct, this might suggest that insofar as people’s preferences are explained in this manner, those preferences are rationally permissible, since relative causal manipulability is normatively relevant. Thus, ascertaining whether the causal manipulability hypothesis is true may shed light on the normative status of such preferences. We investigate the cognitively mediated version of the causal manipulability hypothesis, according to which people’s consciously held beliefs about the relative causal manipulability of events explains (a) and (b). Contrary to expectations, we found no evidence in favour of this view. We suggest that either relative causal manipulability plays an explanatory role, but one that is not cognitively mediated, or that it does not play any role, even if it is sometimes associated with other factors, such as probability, that may play a role in explaining some time biased preferences.

Two theses figure centrally in work on the epistemology of disagreement: Equal Weight (‘EW’) and Uniqueness (‘U’). According to EW, you should give precisely as much weight to the attitude of a disagreeing epistemic peer as you give to your own attitude. U has it that, for any given proposition and total body of evidence, some doxastic attitude is the one the evidence makes rational (justifies) toward that proposition. Although EW has received considerable discussion, the case for U has not (...) been critically evaluated. Endorsing U, we argue, commits one to the highly controversial thesis that whatever fixes your rational attitudes can do so only by fixing what evidence you have. This commitment imposes a relatively demanding requirement on justified belief in U, one that we argue is not satisfied by what is currently the strongest available case for U, due to Roger White [2005]. Our challenge to U makes more trouble for its proponents than do the worries about U expressed by Gideon Rosen [2001] and Thomas Kelly [2010]. Moreover, if Kelly [2010] is correct in thinking that EW “carries with it a commitment to” U—a claim which we accept for reasons similar to Kelly’s but is beyond this paper’s scope (but see Ballantyne and Coffman [forthcoming])—then our challenge to U bears importantly on EW: to the extent that our challenge to U succeeds, EW also suffers.

Molyneux’s question asks whether a person born blind who has learned to identify shapes by touch could, if suddenly granted sight, immediately identify shapes visually. This question has often been used to structure discussions of whether there is a “rational connection” between sight and touch—whether it is possible to rationally doubt whether the same shape properties are both seen and felt. I distinguish two questions under this general heading. The first concerns, roughly, whether the visual and haptic perception of shape (...) is rationally connected in normally sighted perceivers. The second concerns, roughly, whether the visual and haptic perception of shape is rationally connected in all possible perceivers. I argue that real-world implementations of Molyneux’s question are irrelevant to the first question, but potentially relevant to the second. However, I also argue that the second question does not have the philosophical significance it is sometimes claimed to have. In particular, it cannot be used to adjudicate debates about whether the phenomenal character of perceptual experience is primarily determined “externally” by the worldly properties we perceive, or “internally” by physiological or functional properties of our brains.

A vexing problem in contemporary epistemology—one with origins in Plato’s Meno—concerns the value of knowledge, and in particular, whether and how the value of knowledge exceeds the value of mere true opinion. The recent literature is deeply divided on the matter of how best to address the problem. One point, however, remains unquestioned: that if a solution is to be found, it will be at the personal level, the level at which states of subjects or agents, as such, appear. We (...) take exception to this orthodoxy, or at least to its unquestioned status. We argue that subpersonal states play a significant—arguably, primary—role in much epistemically relevant cognition and thus constitute a domain in which we might reasonably expect to locate the “missing source” of epistemic value, beyond the value attached to mere true belief.

In recent years some moral philosophers and political theorists, who have come to be called “luck egalitarians,” have urged that the essence of social justice is the moral imperative to improve the condition of people who suffer from simple bad luck. Prominent theorists who have attracted the luck egalitarian label include Ronald Dworkin, G. A. Cohen, and John Roemer.1 Larry Temkin should also be included in this group, as should Thomas Nagel at the time that he wrote Equality and Partiality.2 (...) However, each of these theorists asserts a different position. The common ground, if any, is obscure. The idea of luck that is invoked is not transparently clear. Anyway, the term “luck egalitarianism” was coined by a critic of the doctrine, and tendentiously defined to denote an extreme version of the view that looks implausible from the start.3 With some justice Ronald Dworkin, perhaps the chief architect of the luck egalitarian position, has denied that he is a luck egalitarian.

It is now widely expected that climate change will be serious enough that a very large number of people will be displaced from their homes because of events relating to or resulting from climate change. Such events may include rising sea levels (and resulting increased salination of ground water), stronger hurricanes and tropical storms, drought, floods, increased and more intense wildfires, and other extreme or (previously) unusual weather events. Although estimates vary widely, it seems very likely that many millions of (...) people—perhaps hundreds of millions if sufficient precautions are not taken—will be forced from their homes by these events related to climate change. In the public imagination, much of the attention has been on ‘climate refugees’, where this is taken to mean people who have crossed borders. However, there is good reason to believe that a very large percentage—probably a significant majority—of displacement resulting from climate change will be, or could be, internal. In this chapter I argue that there are likely to be a large number of cases where internal displacement related to climate change is of international concern, and where, therefore, states have significant moral reasons to provide assistance, either directly to those displaced, or else to the state in which the displacement has taken place. My claim is that internal displacement arising from climate change is of international concern and so grounds a duty of aid by states able to provide it, when this displacement threatens the basic human rights of those displaced, and when the local or domestic government cannot or will not take the necessary steps to meet the needs and protect the rights of those who are displaced.

Kasper Lippert-Rasmussen’s interesting criticisms of the ideal of equality of opportunity for welfare provide a welcome occasion for rethinking the requirements of egalitarian distributive justice.1 In the essay he criticizes I had proposed that insofar as we think distributive justice requires equality of any sort, we should conceive of distributive equality as equal opportunity provision. Roughly put, my suggestion was that equality of opportunity for welfare obtains among a group of people when all would have the same expected welfare over (...) the course of their lives if each behaved as prudently as it would be reasonable to expect her to behave. My specific proposal was more demanding, holding that when an age cohort reaches the onset of responsible adulthood, they enjoy equal opportunity for welfare when for each of them, the best sequence of choices that it would be reasonable to expect the person to follow would yield the same expected welfare for all, the second-best sequence of choices would also yield the same expected welfare for all, and so on through the array of lifetime choice sequences each faces. (In the jargon of my 1989 essay, equal opportunity for welfare obtains when everyone faces effectively equivalent sets of life options.). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Grounding Psychiatry in the Body and the Social WorldLaurence J. Kirmayer, MD, FRCPC, FCAHS, FRSC (bio)The sensing body is like an open circuit that completes itself only in things, in others, in the surrounding earth.—David Abram (2012)Giulio Ongaro has written an interesting set of papers that aim to advance our thinking about ‘externalist’ (i.e., social) approaches to psychiatry by rehearsing an enactivist account of mental disorder and elaborating an (...) ethnographic example of social explanation rooted in a different cultural ontology and system of healing. I am completely onboard with his calls for more attention to the social world in psychiatric theory, research, and practice. What is especially novel in his work is the use of ethnographic research to inform philosophical thinking about psychiatry.Despite my enthusiasm for this effort, I have three concerns with his argument that I can only briefly outline in this commentary: i) the lack of attention to a large body of work in social epidemiology, psychosomatics, and cultural psychiatry that speaks directly to the goals of the biopsychosocial (BPS) approach and that vitiates much of the recent critique of that model; ii) the use of an ethnographic example to idealize an ‘externalist’ system of medicine that patently cannot address the many social structural and sociophysiological processes that psychiatry needs to understand; and iii) most importantly from a philosophical perspective, the fact that the enactivist framework he endorses actually breaks down the distinctions between internalist/externalist psychiatry and naturalist/constructivist ontologies around which he organizes his critique and proposed remedy (Kirmayer & Ramstead, 2017).Integration and the BPS ApproachOngaro’s first paper begins by acknowledging the recent critiques of the BPS approach that claim the BPS leaves vague or underspecified the ways in which the biological, psychological and social domains interact to give rise to mental disorders and how they can be included in systematic case formulation to guide assessment and treatment [End Page 315] intervention. Ongaro notes that current efforts to elaborate an embodied, enactivist approach to psychiatry hold the promise of outlining a more systematic approach to the relationship between levels or domains in the BPS. However, he argues this still leaves psychiatry with excessive emphasis on ‘internalizing’ explanations that appeal to biological or psychological processes within the person to characterize mental disorders. He suggests that this needs to be complemented by an externalizing approach that gives due weight to social processes. The dominant approaches leave the social world underspecified and he notes psychiatry lacks an “ontology of the social.”To some extent, this recent critique—not by Ongaro but by some of the authors he cites—reveals a lack of familiarity or engagement with a rich literature in social epidemiology, psychosomatics and sociosomatics that has long demonstrated the close links between social and physiological processes (Krieger, 2021). This research has produced multiple examples of these relationships detailing their mechanisms and dynamics in ways that do not privilege internal processes. There is no problem identifying many specific instances of these links; for example, research has examined how exposure to racism and discrimination results in increased risk for psychiatric disorders (Kirkbride et al., 2024). We have listed many other such mechanisms related to depression in a recent paper (Gómez-Carrillo & Kirmayer, 2023). This work does not yield a single overarching model or explanation but reveals diverse kinds of mechanisms that interact in a multilevel system that includes both dynamic and linguistic modes (Gómez-Carrillo et al., 2023). Integration occurs in the functioning of this system and cannot be captured in any monolithic theory. This is not a limitation of the BPS, simply a reflection of the complexity of human beings.Can we have a general theory of the links between dimensions or domains in the BPS or will it always remain a piecemeal account that depends on the details of specific systems? Given the many different kinds of processes involved, it seems unrealistic to expect a totalizing theory. If so, both research and clinical work need practical ways to assess the myriad pathways and processes involved in psychiatric disorders in order to formulate cases efficiently, identify a manageable subset of factors to consider in a...

One proposed explanation for a particular kind of temporal preference lies in a disparity between the emotional intensity of memory compared to anticipation. According to the memory/anticipation disparity explanation, the utility of anticipation of a particular event if that event is future, whether positive or negative, is greater than the utility of retrospection of that same event if it is past, whether positive or negative, and consequently, overall utility is maximized when we prefer negative events to be located in the (...) past rather than the future, and positive ones in the future rather than the past. To have this preference is to be (at least apparently) future biased. If this explanation is correct, it would tend to confer rational justification upon these preferences. This paper empirically investigates this explanation. Our results suggest that, at most, this explanation might be a partial one of some people’s preferences some of the time, rather than a general explanation of future bias. In turn, this lends some indirect support to a competing explanation that appeals to temporal asymmetries in emotion and attention. Since that explanation would arguably tend not to confer rational justification upon (apparently) future-biased preferences, we argue that our findings provide some reason to be skeptical that these preferences are, in general, rationally justified.

It is now standard in the literature on reasons and rationality to distinguish normative reasons from motivating reasons. Two issues have dominated philosophical theorising concerning the latter: (i) whether we should think of them as certain (non-factive) psychological states of the agent – the dispute over Psychologism; and (ii) whether we should say that the agent can Φ for the reason that p only if p – the dispute over Factivism. This paper first introduces a puzzle: these disputes look very (...) much like merely verbal disputes about the meaning of phrases like `S’s reason’ in motivating reasons ascriptions, and yet charity requires us to think that something substantive is afoot. But what? The second aim of the paper is to extract substantive theses from certain natural arguments for Psychologism and Anti-Factivism – theses which are versions of a controversial view of the nature and normative structure of rationality. The paper ends by arguing against these substantive theses on phenomenological and ethical grounds. The upshot is that proponents of Psychologism and Anti-Factivism are either engaged in the project of defending merely verbal theses or they’re engaged in the project of defending false substantive ones.

After briefly describing the philosophy of personalism this article assesses each of three normative leadership paradigms in terms of five major themes of this phenomenological philosophy. Servant leadership appears to be closest to personalism. The critical ingredient for servant leadership is also personalism’s starting point, i.e. the dignity of each human person. A genuine servant leader works with his followers in building a community of participation and solidarity. However, some claim that servant leaders are subject to manipulation by their followers. (...) If so, and if transformational leaders, when too successful, gain too much power or manipulate using bogus empowerment, a superior approach might be provided by a combination in which a morally tough servant leader adopts certain transforming behaviors of Bass’s altruistic transformational leader. The leader and the followers would focus on a jointly formulated and refined vision, avoiding manipulation by any party through a mutual commitment to participation, solidarity of community, and respect for each person.

If an array of goods is for sale on a market, one’s wealth, the tradeable resources one owns, determines what one can purchase from this array. One’s income is the increment in wealth one acquires over a given period of time. In any society, we observe some people having more wealth and income, some less. At any given time, in some societies average wealth is greater than in others. Across time, we can observe societies becoming richer or poorer and showing (...) more or less equal distributions of wealth among their members. Does it matter from an ethical standpoint whether some people have more income and wealth than others? Does securing a more equal distribution of income and wealth either constitute the achievement of something that is intrinsically morally desirable or serve as a reliable means to the achievement of some intrinsic moral value? If we suppose that justice demands equalizing the income of wealth of persons in many circumstances, what principles of justice generate this demand? (shrink)

The principal question of this paper is: Why are religious values special in refusal of lifesaving medical treatment? This question is approached through a critical examination of a common kind of refusal of treatment case, one involving a rational adult. The central value cited in defence of honouring such a patient's refusal is autonomy. Once autonomy is isolated from other justificatory factors, however, possible cases can be imagined which cast doubt on the great valuational weight assigned it by strong anti-paternalists. (...) This weight is sufficient, in their estimation, to justify honouring the patient's refusal. There is thus a tension between the strong anti-paternalist's commitment to the sufficiency of autonomy and our intuitions respecting such cases. Attempts can be made to relieve this tension, such as arguing that patients aren't really rational in the circumstances envisaged, or that other values, such as privacy or bodily integrity, if added to autonomy, are sufficient to justify an anti-paternalistic stance. All such attempts fail, however. But what does not fail is the addition of religious freedom, freedom respecting a patient's religious beliefs and values. Why religious freedom reduces the tension is then explained, and the specialness of religious beliefs and values examined. (shrink)

Condensed detachment is usually regarded as a notation, and defined by example. In this paper it is regarded as a rule of inference, and rigorously defined with the help of the Unification Theorem of J. A. Robinson. Historically, however, the invention of condensed detachment by C. A. Meredith preceded Robinson's studies of unification. It is argued that Meredith's ideas deserve recognition in the history of unification, and the possibility that Meredith was influenced, through ukasiewicz, by ideas of Tarski going back (...) at least to 1939, and possibly to 1930 or earlier, is discussed. It is proved that a term is derivable by substitution and ordinary detachment from given axioms if and only if it is a substitution instance of a term which is derivable from these axioms by condensed detachment, and it is shown how this theorem enables the ideas of ukasiewicz and Tarski mentioned above to be formalized and extended. Finally, it is shown how condensed detachment may be subsumed within the resolution principle of J. A. Robinson, and several computer studies of particular Hilbert-type propositional calculi using programs based on condensed detachment or on resolution are briefly discussed. (shrink)

Prior research has not found a meaningful relationship between digital piracy and moral development, possibly because students do not recognize digital piracy as a moral issue.

Some of (...) the stages of moral development are found to be associated with moral development. Proximity to the victim reduces the acceptability of music piracy. (shrink)

In recent years, third-party forgiveness has received renewed attention, much of it negative. While a few have undertaken important attempts to defend or expound accounts of third-party forgiveness, many suspect that it is incoherent, vicious, or both. If true, this would be bad news for Christians, for Christians rely on notions of third-party forgiveness for their accounts of salvation and pastoral authority. I think there is reason to think that some notions of third-party forgiveness can overcome the critics’ worries. In (...) what follows, I argue that third-party forgiveness is more common, coherent, salutary, and diverse in species than many critics suppose. After considering key objections to third-party forgiveness, I offer a constructive account of it that makes sense of these objections while also defending the underlying concept and act. What emerges from this defense is a newfound appreciation for the diverse species of third-party forgiveness. Still, some of these species are more intelligible and safeguarded from declension than others, and I conclude by examining the limits of third-party forgiveness by considering its most contentious species.

If, as it is usually understood, incommensurable theories must be compatible then one need never choose between two such theories. But if theories were incompatible and incommensurable one would have to choose between them. What if they are incompatible only outside the domain of observation? The fact that Darwin's biology can clash with Kelvin's physics (each with their respective auxiliary assumptions) regarding the age of the earth shows how commensurable theories may yet be incompatible. But it also shows that they (...) need not be alternatives--i.e. that one may not be able to simply and satisfactorily replace the other in our world view. But standard examples of scientific revolutions consist of the replacement of one theory by another in one's world view. These alternative theories must therefore be more than merely incompatible--what do they share if not content? (I.e. they must be commensurable.). (shrink)

We read the four commentaries on our article with much interest.1 Each response provides stimulating discussion, and below we have attempted to respond to specific issues that they have raised. We regret that we are not able to respond point-by-point to each of them. However, before our responses, it may benefit the reader if we briefly summarise the claims in our article. First, we hold two presuppositions: (1) xenotransplantation research will inevitably continue for the foreseeable future, and (2) causing suffering (...) and pain requires sufficient justification and should be mitigated where possible. Second, based on these two presuppositions, we posit an argument for the further genetic modification of pigs for xenotransplantation that would eliminate certain experiences of pain and suffering should it become possible to do so. Gibson,2 in his commentary, is sceptical—for good reason—that ‘xenotransplantation-motivated disenhancement would be a temporary stopgap until the organ and tissue shortage problem is solved via less contentious means’. Gibson’s argument is grounded in the fact that the biotechnology industry—of which xenotransplantation is part of—is beholden to economic and market forces that would likely perpetuate constancy, thereby making it difficult to transition away from using disenhanced genetically engineered pigs for xenotransplantation. This point is well taken, …. (shrink)

Excitation at widely dispersed loci in the cerebral cortex may represent a neural correlate of consciousness. Accordingly, each unique combination of excited neurons would determine the content of a conscious moment. This conceptualization would be strengthened if we could identify what orchestrates the various combinations of excited neurons. In the present paper, cholinergic afferents to the cerebral cortex are hypothesized to enhance activity at specific cortical circuits and determine the content of a conscious moment by activating certain combinations of postsynaptic (...) sites in select cortical modules. It is proposed that these selections are enabled by learning-related restructuring that simultaneously adjusts the cytoskeletal matrix at specific constellations of postsynaptic sites giving all a similar geometry. The underlying mechanism of conscious awareness hypothetically involves cholinergic mediation of linkages between microtubules and microtubule-associated protein-2 . The first reason for proposing this mechanism is that previous studies indicate cognitive-related changes in MAP-2 occur in cholinoceptive cells within discrete cortical modules. These cortical modules are found throughout the cerebral cortex, measure 1–2 mm2, and contain approximately 103–104cholinoceptive cells that are enriched with MAP-2. The subsectors of the hippocampus may function similarly to cortical modules. The second reason for proposing the current mechanism is that the MAP-2 rich cells throughout the cerebral cortex correspond almost exactly with the cortical cells containing muscarinic receptors. Many of these cholinoceptive, MAP-2 rich cells are large pyramidal cell types, but some are also small pyramidal cells and nonpyramidal types. The third reason for proposing the current mechanism is that cholinergic afferents are module-specific; cholinergic axons terminate wholly within individual cortical modules. The cholinergic afferents may be unique in this regard. Finally, the tapering apical dendrites of pyramidal cells are proposed as primary sites for cholinergic mediation of linkages between MAP-2 and microtubules because especially high amounts of MAP-2 are found here. Also, the possibility is raised that muscarinic actions on MAP-2 could modulate microtubular coherence and self-collapse, phenomena that have been suggested to underlie consciousness. (shrink)

A theoretical approach relying on quantum computation in microtubules within neurons can potentially resolve the enigmatic features of visual consciousness, but raises other questions. For example, how can delicate quantum states, which in the technological realm demand extreme cold and isolation to avoid environmental ‘decoherence’, manage to survive in the warm, wet brain? And if such states could survive within neuronal cell interiors, how could quantum states grow to encompass the whole brain? We present a physiological model for visual consciousness (...) that can accommodate brain-wide quantum computation according to the Penrose–Hameroff ‘Orch OR’ model. In this view, visual consciousness occurs as a series of several-hundred-millisecond epochs, each comprising ‘crescendo sequences’ of quantum computations occurring at ∼40 Hz. (shrink)

Should engineering ethics be taught? Despite the obvious truism that we all want our students to be moral engineers who practice virtuous professional behavior, I argue, in this article that the question itself obscures several ambiguities that prompt preliminary resolution. Upon clarification of these ambiguities, and an attempt to delineate key issues that make the question a philosophically interesting one, I conclude that engineering ethics not only should not, but cannot, be taught if we understand “teaching engineering ethics” to mean (...) training engineers to be moral individuals (as some advocates seem to have proposed). However, I also conclude that there is a justification to teaching engineering ethics, insofar as we are able to clearly identify the most desirable and efficacious pedagogical approach to the subject area, which I propose to be a case study-based format that utilizes the principle of human cognitive pattern recognition.

In lieu of an abstract, here is a brief excerpt of the content:IntroductionStuart J. Youngner (bio), Laura A. Siminoff (bio), and Renie Schapiro (bio)This issue of the Kennedy Institute of Ethics Journal (KIEJ) centers on a piece of empirical research. The motivation behind the study of Laura Siminoff, Christopher Burant, and Stuart Youngner (2004) was to find out more about what the general public understands and believes about when a person is dead. More specifically, the study tried to determine how (...) members of the public define death, especially their acceptance and interpretation of the medical concept of "brain death," and their attitudes toward the so-called "dead donor rule," an informal but powerful social and legal norm insisting that the taking of organs for transplantation not cause the death of the source of those organs.As the demand for organs increases and the waiting list grows, the United States has explored multiple ways to expand the pool of potential donors. One approach has been to gerrymander (coherently or not) the line between life and death to shift patients who are extremely compromised but traditionally considered to be in the living category into the dead category. In this way, the dead donor rule remains technically intact. This reasoning is explicit in the report of the Harvard Medical School Ad Hoc Committee (1968) that "introduced" "brain death" to the American culture. Since then, other efforts to redraw the line have been proposed and rejected.One alternative to gerrymandering is to consider under what conditions, if any, it is morally acceptable to violate the dead donor rule. Some would argue that this alternative is the more "honest" approach. Rather than sidestepping moral problems by calling people dead, it brings the moral problems to the surface where the necessity of sticking to the rule can be considered on its own merits. However, when the Journal of the American Medical Association printed a position paper that proposed making anencepahlic newborns an exception to the dead donor rule, along with arguments about why this was acceptable, the outcry was so great that the proposal was retracted (AMA 1995).Clearly, our society has identified organ transplantation as a priority, although two papers in this volume (those by Courtney Campbell and by Megan Crowley-Matoka and Robert Arnold) take issue with that prioritization. The fact that the donor pool has remained relatively stable (and inadequate) despite massive efforts [End Page 211] to increase it speaks, at least in part, to the cultural and legal resistance to "new" ways to procure more organs. Voluntarism seems to have peaked. Financial incentives clash with the heavily endorsed notion of the "gift of life" and seem to many to violate the dignity of the human body. Presumed consent or eminent domain, in which the community has a greater claim to a person's organs than that person or his/her family, go against the grain of American individual freedom and the ethos of patient autonomy.Abandoning the dead donor rule generally is regarded as an even tougher sell to the American public and its legislators. The study by Siminoff and colleagues attempts, among other things, to gauge just how tough this sell would be. What the data actually demonstrate is a matter of interpretation, and this issue of the KIEJ is devoted to some of those interpretations. The authors, with the exception of Daniel Hausman, came together for a meeting in Cleveland, Ohio, during which the study's methods and data were presented with time for questions, clarifications, and general discussion. The authors then worked with the editors to generate the papers printed in this volume.The issue begins with a presentation of the study conducted by Siminoff and colleagues. The same paper also appears in the journal Social Science and Medicine, where it includes the conclusions of the authors (Siminoff, Burant, and Youngner 2004). In the current volume, we present only the methodology of and data from the study, allowing a number of distinguished commentators to offer their own conclusions and reflections.The first response comes from Tracy Schmidt, Executive Director of Intermountain Donor Services, one of our nation's organ procurement organizations (OPOs). For years, organ procurement professionals have reported anecdotal stories about families who wished to donate organs of... (shrink)

Ethicists have raised a variety of concerns about solar radiation management (SRM). This essay investigates the specific worries associated with artificity: Does SRM transform the planet into an artifact? Should experimental SRM strategies be implemented if the consequences are unpredictable? These worries have led some to strongly reject SRM. But the conceptual framework used by environmental scientists to understand the scope of management interventions might offer a way to adequately defuse the perceived ethical concerns about artificity. Concepts from theories of (...) scale, like discontinuity and panarchy, are discussed to demonstrate how the artificity arguments appear to depend on disputable premises. (shrink)

Jack Spencer argues we should reject a decision rule called MaxRat because it's incompatible with this principle: If you know that you will choose an option, x, and you know that x is better than every other option available to you, then it is permissible for you to choose x. I agree with Spencer that defenders of MaxRat should reject this principle. However, I disagree insofar as he suggests that he and orthodox causalists are in a position to accept it. (...) Both orthodox CDT and Spencer's own theory of rational choice are incompatible with the principle as well. It is surprising to realise, but all are agreed: it can be irrational to knowingly choose the best. (shrink)

In this article, the background of the phrase ‘and live’ in Hebrews 12:9 is investigated. Although most scholars are silent on the matter, the majority of those who venture to propose a possible background vaguely refer to Proverbs 6:23b. Only a handful of scholars propose other backgrounds. This article aims to fill this lacuna. The first part of the article gives an overview of the argument of Hebrews 12:9 in its context to determine a baseline for the interpretation of the (...) phrase ‘and live’. This is followed by investigating eight possible backgrounds of the phrase and weighing arguments for and against each proposal. Next, the article integrates the findings and concludes that, of all the proposed backgrounds, Deuteronomy 8:1–5 fits the best. If this is correct, the writer uses the phrase ‘and live’ in Hebrews 12:9 to positively exhort his hearers to live life as their heavenly Father intended it, now up to eternity, by wholeheartedly obeying his revelation in his Son.

In ‘Minds, Machines and Gödel’, 1961, J. R. Lucas proposed that Godel's theorem made possible a refutation of mechanism—the thesis that mind is wholly comprehensible as a consistent, rule-governed machine. A sympathetic reading of Lucas's argument might run something as follows: ‘If I am a machine then it will be possible in principle to give a specification of the consistent formal system, L, that represents me. If this formal system were handed to me, I would be able to prove a (...) Gödel sentence, G, which L could not generate—that is, L could not model my proving G. But since I have proved G, L is inadequate as a model of my cognitive process.’. (shrink)

The great mathematician, physicist, and philosopher, Hermann Weyl, once called mathematics the “science of the infinite.” This is a fitting title: contemporary mathematics—especially Cantorian set theory—provides us with marvelous ways of taming and clarifying the infinite. Nonetheless, I believe that the epistemic significance of mathematical infinity remains poorly understood. This dissertation investigates the role of the infinite in three diverse areas of study: number theory, cosmology, and probability theory. A discovery that emerges from my work is that the epistemic role (...) of the infinite varies, often in surprising ways, across different domains of knowledge. -/- My first chapter examines the role of mathematical infinity in number theory. It is reasonable to think that theorems concerning finite patterns and structures in the natural numbers are particularly “simple” or “elementary.” Indeed, such statements are comprehensible to a wide range of investigators, regardless of their mathematical training. One might then expect proofs of these theorems to be similarly comprehensible. However, many proofs, especially those that utilize only finitary methods, are exceedingly difficult to understand. Consequently, one finds that finitary theorems are often re-proved using infinitary techniques. My claim is that this is because infinitary proofs are often explanatory, while finitary proofs are not. This chapter analyzes why this is the case. Along the way, I investigate other questions of long-standing interest in the philosophy of mathematics, e.g., the role of purity/impurity ascriptions and the nature of the content of a theorem. In particular, I diagnose the explanatory potential of the infinite by articulating a new construal of content. This new construal both saves intuitive epistemic ascriptions made in mathematical practice and explains the unexpected role of the infinite in providing explanatory proofs of finitary statements. Thus, in number theory, my claim is that the infinite often plays an explanatory role. -/- My second chapter turns to the role of the infinite in cosmology. It investigates a question much discussed by philosophers and physicists alike: is the spatial extent of the universe finite or infinite? Contemporary cosmological research has indicated that one of the essential determinants of the extent of the universe is the topology we ascribe to space. Topology is a global property, which may suggest that it is not testable through local observation. Nonetheless, some cosmologists have indicated that it may be empirically detected, thereby providing an answer to the question of spatial extent. I argue that, in fact, the epistemic status of the topology of space is extremely subtle and not well captured by any of the categories commonly employed by philosophers of science. In particular, I argue that topological properties are neither empirical nor a priori (even in suitably weakened senses). Furthermore, I claim that we should prefer topological properties that generate finite universe models (consistent with our best data) in order to avoid extremely thorny issues concerning the physics of an infinite universe. I argue for such a preference on the grounds of the simplicity and explanatory power of finite universe models. Thus, in cosmology, my claim is that the finite often plays an explanatory and simplifying role. -/- My third chapter investigates several paradoxes that arise in the foundations of infinitary probability theory: the Label Invariance Paradox, God’s Lottery, and Bertrand’s Paradox. I argue that these have been poorly understood because they do not expressly concern probability theory, but rather our intuitions about—and formal techniques for dealing with— infinite sets. The paradoxes in question are, in fact, symptoms of our complete reliance upon Cantorian cardinality and its associated criterion of sameness of “size.” That is, two sets have the same cardinality if and only if the elements of the sets can be placed in 1-1 correspondence. When applied to infinite sets, this criterion produces counterintuitive verdicts. For instance, given a fair lottery on the natural numbers, we expect that the probability of drawing an even number is 1/2, and likewise for drawing an odd number. However, one can construct “relabellings” of the naturals such that the probability of drawing an even number remains 1/2, while the probability for drawing an odd number becomes 1/4. I argue that, ultimately, it is the coarseness of Cantorian cardinality that generates the probabilistic paradoxes. I then propose that finer-grained measures of infinite sets from mathematical logic and number theory can help to dissolve the paradoxes in question. Thus, in probability theory, we find that particular kinds of infinitary techniques effectively systematize our theory, while others lead to paradox. (shrink)

Staggering advances in biotechnology within the past decade have given rise to pharmacological, surgical and prosthetic techniques capable of enhancing human functioning rather than merely treating or preventing disease. Bioenhancement technologies range from nootropics capable of enhancing cognitive abilities to distraction osteogenesis, a surgical technique capable of increasing height through limb lengthening. This paper examines whether the use of bioenhancements falls inside or outside the proper boundaries of healthcare, and if so, whether clinicians have professional responsibilities to administer bioenhancements to (...) patients. After explicating two theoretical approaches to the concept of health, one objectivist and the other constructivist, I contend that clinicians' corresponding professional responsibilities hinge on which philosophical account of health is endorsed, and illustrate how the lack of analytic clarity with respect to this concept can lead to defective positions on the place of bioenhancements in healthcare. With this conceptual framework in place, an account of health as a cluster concept that incorporates both constructivist and objectivist components is developed and defended. (shrink)

5-43 This article aims to consider the robust field of environmental history as a whole, as it stands and as it has developed over the past twenty-five years around the world. It necessarily adopts a selective approach but still offers more breadth than depth. It treats the links between environmental history and other fields within history, and with other related disciplines such as geography. It considers the precursors of environmental history, its emergence since the 1970s, its condition in several settings (...) and historiographies. Finally it touches on environmental history’s relationship to social theory and to the natural sciences as they have evolved in recent decades. It concludes that while there remains plenty of interesting work yet to do, environmental history has successfully established itself as a legitimate field within the historical profession, and has a bright future, if perhaps for discouraging reasons.

One way to think about capitalism-versus-socialism is to examine the extent to which capitalist economic institutions are compatible with the fulfillment of socialist ideals. The late G. A. Cohen has urged that the two are strongly incompatible. He imagines how it would make sense for friends to organize a camping trip, distills the socialist moral principles that he sees fulfilled in the camping trip model, and observes that these principles conflict with a capitalist organization of the economy. He adds that (...) these principles are ethically attractive, so if it is feasible to organize the economy on the camping trip model, we ought to do so. This essay argues to the contrary that for all that has been said, capitalist economic arrangements might be in the set of institutional arrangements that overall would best fulfill the camping trip principles, and anyway, the principles themselves ought to be rejected, so the question whether or not a capitalist set-up might satisfy these principles should not interest us. The grounds for rejecting the camping trip principles support a form of welfarist consequentialism that denies that equality of distribution of any sort is per se ethically desirable and also denies that liberal freedoms to live as one chooses are per se morally desirable. Equality and freedom should rather be regarded as in the light of possible means (or hindrances) to advancing good for people, fairly distributed. (shrink)

Kengo Miyazono, in his work Delusions and Beliefs, defends a teleo-functional account of delusions. In my contribution to this symposium, I question one of Miyazono’s motivations for appealing to teleo-functionalism over its main rival, dry-functionalism. Miyazono suggests that teleo-functionalism, unlike dry-functionalism, can account for the compatibility of the theses (i) that delusions are genuine doxastic states (doxasticism about delusions) and (ii) that delusions do not perform the typical causal roles of beliefs (the causal difference thesis). I argue, however, that there (...) are also ways for dry-functionalism to account for this compatibility. If what I have to say is correct, then Miyazono is perhaps too hasty—at least in one important respect—to opt for teleo-functionalism over dry-functionalism. Dry-functionalism has an equally good chance of satisfying some of Miyazono’s explanatory goals. (shrink)

According to tradition, logic is normative for reasoning. According to many contemporary philosophers of logic, there is more than one correct logic. What is the relationship between these two strands of thought? This paper makes two claims. First, logic is doubly normative for reasoning because, in addition to constraining the combinations of beliefs that we may have, logic also constrains the methods by which we may form them. Second, given that logic is doubly normative for reasoning, a wide array of (...) logical pluralisms are inconsistent with the normativity of logic as they entail contradictory claims about how agents ought to reason. Thus, if logic is normative for reasoning, these pluralisms are untenable. (shrink)

It is held by many philosophers that it is a consequence of epistemic contextualism that speakers are typically semantically blind, that is, typically unaware of the propositions semantically expressed by knowledge attributions. In his ?Contextualism, Invariantism and Semantic Blindness? (this journal, 2009), Martin Montminy argues that semantic blindness is widespread in language, and not restricted to knowledge attributions, so it should not be considered problematic. I will argue that Montminy might be right about this, but that contextualists still face a (...) serious and related problem: that it is a consequence of epistemic contextualism that subjects are typically unaware of contents conveyed by knowledge attributions, independently of whether these are semantic or non-semantic contents. Even if semantic blindness is widespread in language, it does not seem that content unawareness of this sort is. (shrink)

First-person methodologies have been criticized for their inability to arrive at reliable and verifiable knowledge of the contents of conscious experience. Consciousness, however, is not its contents, but the cognitive capacity that makes those contents available. That capacity is directly and uniquely accessible to first-person inquiry, provided a suitable methodology can be developed. As a framework for such inquiry, this paper distinguishes two structures that give rise to conscious contents: narrative and story. While narratives are told, stories are inhabited. Stories (...) are fundamental to conscious experience: an event is conscious only if it fits the presently unfolding story. While third-person inquiry relies on withdrawing from story into narrative, first-person inquiry can take place within the story. In place of the reductive objectivity of third-person science, first-person inquiry can cultivate an engaged objectivity, immersed in the story but not bound to it, that makes the phenomenon of consciousness available to be known. Communities of inquiry practising such a first-person style of inquiry could develop criteria for assessing advances in knowledge and for research programmes appropriate to furthering such advances.

Every living science, especially in its early stages, is compelled to devise fresh terms, either by coining new words or by giving new meanings to old ones. Unless and until these fresh terms become absorbed in the vocabulary of everyday speech, their unfamiliarity makes them a target for the shafts of the humourist. There can be no doubt that in the late fifth century B.C. literary criticism was still a new science. We can trace its beginnings in the treatises of (...) the Sophists, many titles of which have been handed down to us. Strepsiades' lesson in metric, though of itself amusing enough, would certainly gain in topical appropriateness if enacted at a time when such investigations were not only much in the air, but were still novel. And the whole ‘Agon’ of the Frogs, the character of which is forecasted in lines 796–802, depicts in the strongest colours the contrasted views of technician and inspirationist. We should therefore naturally expect a play of such a kind, written at such a time, to be full of technical jargon, barely understood by the ‘man in the street,’ and forming the object of his half-contemptuous amusement. That is, I believe, exactly what we do find, to an extent insufficiently recognized. Professor Radermacher, in his recent edition of the Frogs, has rendered valuable service by pointing out the frequent occurrence in that play of technical terms which meet us later in Dionysius of Halicarnassus and other critics. But I believe that technical language lurks unsuspected in many other passages, though the precise meaning may often be beyond recovery. (shrink)

In her article, "Thinking and Moral Considerations," Hannah Arendt provides a provocative approach to the question of evil by suggesting that banal evil-the most common kind-may arise directly from thoughtlessness. If that is so, thinking may provide an antidote to evil. Learning to think would then offer the individual and society protection against the dangers of thoughtless evil. She further suggests that thinking may clear the way for a form of judging that "when the chips are down" may turn people (...) toward right rather than wrong, beauty rather than ugliness. In this essay I address her claim by noting an example of apparently thoughtless evil, the murder of Duncan by Macbeth, and by showing how this event clarifies Arendt's thesis, including both its weaknesses and its strengths. The use of Macbeth will amount to a sketch of certain features of the play particularly relevant to this ethical issue, followed by an analysis of ways Arendt's thesis connects with the murder of Duncan.

Under the influence of recurrent deleterious mutation and selection, asexual and sexual populations reach a deterministic equilibrium with individuals carrying 0,1,2,. . . harmful mutations. When a favourable mutation (aA) occurs in an asexual population it will usually occur in an individual who has one or more (k) deleterious mutations. Muller's ratchet then applies as A will thereafter never occur in an individual with less than k mutations. If the selective advantage of A is less than the selective disadvantage of (...) k harmful mutations then A will not spread. If it is greater it may spread carrying k deleterious mutations to fixation. Sexual populations are not affected in this way. A will spread through the population experiencing genomes with 0,1,2,. . . deleterious mutations in accordance with the deterministic equilibrium. (shrink)

Here we discuss the challenge posed by self-organization to the Darwinian conception of evolution. As we point out, natural selection can only be the major creative agency in evolution if all or most of the adaptive complexity manifest in living organisms is built up over many generations by the cumulative selection of naturally occurring small, random mutations or variants, i.e., additive, incremental steps over an extended period of time. Biological self-organization—witnessed classically in the folding of a protein, or in the (...) formation of the cell membrane—is a fundamentally different means of generating complexity. We agree that self-organizing systems may be fine-tuned by selection and that self-organization may be therefore considered a complementary mechanism to natural selection as a causal agency in the evolution of life. But we argue that if self-organization proves to be a common mechanism for the generation of adaptive order from the molecular to the organismic level, then this will greatly undermine the Darwinian claim that natural selection is the major creative agency in evolution. We also point out that although complex self-organizing systems are easy to create in the electronic realm of cellular automata, to date translating in silico simulations into real material structures that self-organize into complex forms from local interactions between their constituents has not proved easy. This suggests that self-organizing systems analogous to those utilized by biological systems are at least rare and may indeed represent, as pre-Darwinists believed, a unique ascending hierarchy of natural forms. Such a unique adaptive hierarchy would pose another major challenge to the current Darwinian view of evolution, as it would mean the basic forms of life are necessary features of the order of nature and that the major pathways of evolution are determined by physical law, or more specifically by the self-organizing properties of biomatter, rather than natural selection.

One of the most famous inscriptions to have survived from ancient Rome is the acta of the Ludi Saeculares of 17 b.c., and one of the most evocative of all epigraphic sentences occupies a line to itself : Carmen composuit Q. Horatius Flaccus. This reference to the author of the Carmen Saeculare, says Fraenkel, ‘was the result of a carefully considered decision of the highest authorities’. The degree of careful consideration is initially evident from the prominent positioning of the poet's (...) name directly above those of Augustus and Agrippa in the following line. It will also be noticed that the sentence concludes with a clausula which is one of Cicero's favourites. A further refinement emerges, however, if the poet's name is spelled out in full, something precluded by the naming conventions of the inscription:Cārmēn cōmpŏsŭīt ´ Quīntŭs Hŏrātĭūs | Flaccus.The inscribed sentence incorporates an Asclepiad line, the ‘signature’ metre of Odes 1–3, which are framed by Horace's only two poems in stichic Asclepiads. In identifying the author of the Carmen Saeculare, the sentence also acknowledges the collection of poems which won him the commission. (shrink)
