In this paper I will analyse the relationship between metaphor and imagination. This issue has been recently studied by cognitive linguists who appreciate its importance, while other semantic perspectives neglect it. I will analyse the thesis which affirms that metaphors are based on cognitive components which are not logical-propositional but imaginative: the “image schemata” are recurrent models of corporeal experiences, centres of knowledge organization which structure – in a non-propositional form – an amount of salient information. This information emerges from (...) the sensorimotor activities such as: manipulation of objects, spatial orientation and focusing perceptive attention on different goals. According to this theory, imagination is the drive of the entire cognitive experience and, through metaphorical projection, it activates and coordinates the schemata from which the very linguistic activity originates. Starting with empirical studies about the cognitive and neurobiological plausibility of image schemata, I will assert the function of imagination as the trait d’union between experience and cognitive use of the metaphor, through the use of sensory and synesthetic metaphors as mediators among perceptive, physical and linguistic dimensions. I hope future research will concentrate on the relationship between synesthesia and image schemata because of their strong connection with human perceptive, cognitive and neural structures. (shrink)

In philosophy, the criteria for personhood (PH) at a specific point in time (synchronic), and the necessary and sufficient conditions of personal identity (PI) over time (diachronic) are traditionally separated. Hence, the transition between both timescales of a person's life remains largely unclear. Personal habits reflect a decision-making (DM) process that binds together synchronic and diachronic timescales. Despite the fact that the actualization of habits takes place synchronically, they presuppose, for the possibility of their generation, time in a diachronic sense. (...) The acquisition of habits therefore rests upon PI over time; that is, the temporal extension of personal decisions is the necessary condition for the possible development of habits. Conceptually, habits can thus be seen as a bridge between synchronic and diachronic timescales of a person's life. In order to investigate the empirical mediation of this temporal linkage, we draw upon the neuronal mechanisms underlying DM; in particular on the distinction between internally and externally guided DM. Externally guided DM relies on external criteria at a specific point in time (synchronic); on a neural level, this has been associated with lateral frontal and parietal brain regions. In contrast, internally guided DM is based on the person's own preferences that involve a more longitudinal and thus diachronic timescale, which has been associated with the brain's intrinsic activity. Habits can be considered to reflect a balance between internally and externally guided DM, which implicates a particular temporal balance between diachronic and synchronic elements, thus linking two different timescales. Based on such evidence, we suggest a habit-based neurophilosophical approach of PH and PI by focusing on the empirically-based linkage between the synchronic and diachronic elements of habits. By doing so, we propose to link together what philosophically has been described and analyzed separately as PH and PI. (shrink)

In this article I want to construct in a simple and systematic way an ethical theory of animal equality. The goal is a consistent theory, containing a set of clear and coherent universalized ethical principles that best fits our strongest moral intuitions in all possible morally relevant situations that we can think of, without too many arbitrary elements. I demonstrate that impartiality with a level of risk aversion and empathy with a need for efficiency are two different approaches that both (...) result in the same consequentialist principle of prioritarianism. Next, I discuss that this principle can be trumped by an ethic of care principle of tolerated partiality, and a deontological principle of basic right. These three principles represent different kinds of equality that can be applied to animal ethics. Finally, the predation problem leads to the introduction of a triple-N-principle that is related to the value of biodiversity. (shrink)

In a recent contribution to Utilitas Hugh Upton has criticized my defence of utilitarianism against the charge that it is committed to regarding the pleasures taken by sadists in other people's pain as increasing the amount of good in the world and so at least partially offsetting the suffering of the victims. In the present paper I clarify and defend my view that sadists implicitly insult their own human qualities, thus rendering it impossible to respect themselves as human beings, when (...) they enjoy the suffering of others with essentially similar qualities. Distinguishing between happiness and pleasure, I explain why it is not, as Upton thinks, a mere stipulation to deny that the sadist's self-demeaning pleasures are capable of augmenting his happiness.

The ArgumentEugenics is generally regarded as evil; but what was its sin? Racism, class bias, and violation of reproductive freedom, which tainted objectionable eugenic interventions, are not part of the core notion of eugenics. A number of candidates have been suggested as the wrong inherent in eugenics, ranging from statism to the impossibility of consensus on the ideal human being. It is most plausible to view eugenics as sharing moral dilemmas with much of public health, and the critical issues as (...) those of distributive justice. (shrink)

La relación entre el problema de la temporalidad del valor y el de nuestra persistencia diacrónica prácticamente no ha sido explorada hasta ahora. Sin embargo, el análisis de cada una de estas cuestiones puede arrojar luz sobre la otra de manera interesante. Este artículo argumentará que las conexiones entre la asimetría de nuestras actitudes hacia el futuro y el pasado, y la cuestión de nuestra persistencia diacrónica pueden defenderse sin incurrir en modo alguno a una petición de principio. The relation (...) between the problem of the temporality of value and the problem of our diachronic persistence has virtually not been explored so far. However, the analysis of these questions can shed light on each other in an interesting way. This paper argues that an explanation of the connections between the asymmetry of our attitudes towards the future and the past and the question of our diachronic persistence is possible without begging the question in any way.

The work analyzes two competing arguments in the issue of abortion and shows that each requires a different theory of personal identity. Further, I analyze those theories and show what moral premises they are compatible with and what implications there are for the abortion debate.

A central aim within criminal justice ethics is to give a plausible justification concerning which type of acts ought to be criminalized by the state. One of the principles of criminalization which has been presented and critically discussed in the philosophical literature is the Offense Principle. The primary aim of this paper is to argue that unless a rather special and implausible objective list theory of well-being is accepted, the Offense Principle should be subsumed in the Harm Principle.

In this dissertation, I examine the nature and structure of consciousness. Conscious experience is often said to be phenomenally unified, and subjects of consciousness are often self-conscious. I ask whether these features necessarily accompany conscious experience. Is it necessarily the case, for instance, that all of a conscious subject's experiences at a time are phenomenally unified? And is it necessarily the case that subjects of consciousness are self-conscious whenever they are conscious? I argue that the answer to the former is (...) affirmative and the latter negative. In the first chapter, I set the stage by distinguishing phenomenal unity from other species of conscious unity. A pair of conscious states is phenomenally unified if they are experienced together as part of a single experience that encompasses them both. In this and the next two chapters I defend the thesis that, necessarily, for any subject (of conscious mental states) at any time, all of that subject's conscious mental states (at that time) are part of a single, maximal state of consciousness. I call this thesis the "Unity Thesis." I proceed by considering some preliminary questions that might be raised about the Unity Thesis. For instance, the thesis presupposes that it is coherent to talk about parts of mental states. I consider objections by Tye and Searle and argue that the notion of an experiential part is unproblematic. In the remaining pages of the chapter, I present the source of the biggest challenge to the Unity Thesis: the data gathered from split-brain subjects. The Unity Thesis is formulated using the notion of a maximal state of consciousness. In the second chapter, I attempt to precisify this notion in a way that does not pre-emptively decide the debate over the Unity Thesis. In informal terms, a maximal state of consciousness is a sum of conscious states that are i) simultaneous, ii) have the same subject, and iii) all have a conjoint phenomenology. I call this the Consensus View. I then consider two unorthodox views that the Consensus View does not take off the table: the views that a "collective consciousness" and a "spread consciousness" are possible. A collective subject is one that can enjoy the experiences of an indeterminate number of "lesser" subjects of consciousness by sharing them together with those subjects. A spread subject is one that can enjoy the experiences of an indeterminate number of lesser subjects of consciousness, but it does so, not by sharing those experiences with the lesser subjects, but by absorbing the lesser subjects of experience into itself, thereby erasing the traditional boundaries between the entities we intuitively think of as subjects of experience. I argue that, although the Consensus View does not decide against them, these views stretch the bounds of coherence and should not, therefore, be accepted. Having presented an account of what maximal state of consciousness is, I define a stream of consciousness in terms of a maximal states of consciousness. In the rest of chapter two, I consider and argue against a number of different ways of interpreting the split-brain data that are either inconsistent with the Unity Thesis or attribute more than one subject of consciousness to split-brain subjects. Among the views I consider are Lockwood's partial-unity view and the views, by theorists such as Sperry, Koch, Puccetti, Marks, and Tye, that split-brain subjects have two non-overlapping streams of consciousness. In chapter three, I consider a recent attempt by Bayne to account for the split-brain data in a way that does not attribute two streams of consciousness to them. According to Bayne's Switch Model, the consciousness of split-brain subjects can be likened to that of a ball that is passed back and forth between the two hemispheres of the upper-brain. The hemispheres take turns supporting a single stream of consciousness. I consider the empirical data in some detail and argue that the data is not as compatible with the Switch Model as Bayne claims. I close the chapter by presenting the rough outline of an interpretation of the split-brain data that is consistent with both the Unity Thesis and the split-brain data. In chapter four, I turn from defending the Unity Thesis to examining an attempt to account for conscious unity. Rosenthal has offered a theory of conscious unity as an extension of his higher-order theory of consciousness. I consider his account of conscious unity in light of a well-known objection to his theory: the (Representational) Mismatch Objection. It can be asked what it is like for a subject of experience when a higher-order state misrepresents its target first-order state. If what it is like for the subject corresponds to the content of the higher-order state, then it appears as though higher-order representation is unnecessary for conscious experience, for it would appear as though it is possible for a state to be conscious without being represented by a higher-order state. If what it is like corresponds to the content of the lower-order state, then it would again seem as though representation at the higher-order level is unnecessary for conscious experience, for the higher-order state would not seem to be doing any work in generating the experience. I consider and argue against two recent defences of Rosenthal's higher-order theory from the Mismatch Objection. Then I turn to Rosenthal's account of conscious unity. Rosenthal's account posits two mental mechanisms. I refer to the ways of accounting for conscious unity via these two mechanisms as the "gathering strategy" and the "common-ascription strategy" respectively. Both of these strategies, I argue, appear to locate the basis for certain phenomenal facts in higher-order representational facts. This raises a prima facie question: does Rosenthal's account of conscious unity land him square within the sights of the Mismatch Objection? Although the gathering strategy may ultimately be understood in a way that does not make it subject to the Mismatch Objection, Rosenthal has certain commitments that bar this strategy from serving as a complete account of conscious unity. This is problematic for Rosenthal, I argue, because his common-ascription strategy faces some difficult questions. This strategy makes conscious unity due to an implicit expectation a subject of consciousness has that, whenever he or she engages in introspection, an explicit sense of conscious unity will be generated. I argue that it is very difficult to see how such an implicit sense could both avoid the Mismatch Objection and do the work it needs to do in order to account for conscious unity. In chapter five, the discussion turns from the unity of consciousness to self-consciousness. The question that is considered in this and the last chapter is the question whether conscious experience is necessarily accompanied by self-consciousness. The affirmative answer to this question I call the Ubiquity Thesis. I spend some time distinguishing robust conceptions of self-consciousness from minimal conceptions of self-consciousness. The notion of self-consciousness invoked by the Ubiquity Thesis is a minimal one. In spite of the fact that the Ubiquity Thesis invokes only a minimal or thin conception of self-consciousness, I believe the thesis to be false and argue against it. In this chapter I take up the views of Husserl. Husserl is often regarded as the progenitor of the phenomenological tradition, a tradition in which many philosophers affirm the Ubiquity Thesis. I examine and argue against an interpretation of Husserl's work, one defended by Zahavi, according to which Husserl could be seen to defend the Ubiquity Thesis. One claim that Husserl makes is that, in order for an object to become the intentional target of a conscious state, it must be given to consciousness beforehand. It is possible, during acts of deliberate introspection, for consciousness to take itself as its object. On Husserl's view, this requires consciousness to be given to itself beforehand. This self-givenness of consciousness, argues Zahavi, can be seen as a kind of minimal self-consciousness. Husserl has also offered an account of this self-givenness of consciousness and it appears in his discussion of inner time-consciousness. I attempt to argue, using some of Husserl's other views regarding psychological stances (or standpoints), that consciousness is not given to itself outside of the adoption of a certain psychological standpoint. I also offer an alternative way of accounting for inner time-consciousness, one that does not have, as a built-in feature, that consciousness always has itself as a secondary object. In the sixth and final chapter, I take up a contemporary defence of the Ubiquity Thesis. Kriegel, a higher-order theorist like Rosenthal, has argued that every conscious state is conscious in virtue of the fact that it represents itself. This self-representation is understood as a kind of self-consciousness and, thus, his theory can be seen as affirming the Ubiquity Thesis. In the first part of the chapter, I take issue with the way in which Kriegel lays out the conceptual terrain. In particular, Kriegel countenances a property he calls "intransitive state self-consciousness." I argue that this way of speaking is confused. I then turn to considering Kriegel's account. Kriegel identifies the species of self-consciousness that pervades all of conscious experience with a peripheral awareness of one's own mental states. I argue that such a peripheral inner awareness does not accompany all of our mental states and, thus, that Kriegel's views do not give us reason to accept the Ubiquity Thesis. (shrink)

The advent of prenatal genetic diagnosis has sparked debates among ethicists and philosophers regarding parental responsibility towards potential offspring. Some have attempted to place moral obligations on parents to not bring about children with certain diseases in order to prevent harm to such children. There has been no rigorous evaluation of cystic fibrosis in this context. This paper will demonstrate cystic fibrosis to have unique properties that make it difficult to categorise among other diseases with the goal of promulgating a (...) reproductive rule. Once this is established, it will be demonstrated that procreative rules that appeal to future health are inadequate in the era of advancing genetic knowledge. Utilising a specification of Joel Feinberg's ‘open future’ concept outlined by Matteo Mameli, it will offer an analysis of parental obligation that does not constrain parents of potential children with cystic fibrosis with a moral obligation not to bring them about.

Economic Theory normally assumes the so-called homo economicus, a consequential model of rationality. We highlight the main features of this model in opposition to deontology: axiological homogeneity, maximization and agent neutrality. Amartya Sen’s criticism of standard consequentialism copes to those features, and includes commitment and duty in the economic rationality. We analyze his concept of preference to ascertain how far economic rationality can thus go in the direction of deontology. We conclude that, though diminished, the difference between them still remains.

Temkin's book argues that equality is a complex and individualistic value. The critical notice suggests that equality is not as complex as Temkin takes it to be. It contends that Temkin's view does not rest the importance of equality on the moral claims of individuals. A view of equality that is based on individual claims might provide a better explanation of why equality matters even when a gain in quality does not benefit anyone.

the term as used by sunstein seeks to bring together various traditions. however, there are significant differences between uses of the term in the cognitive and the social psychological research, and these differences are accompanied by very distinct evidential criteria. we suggest the term should refer to processes, which means that further evidence is required.

If X loves Y does it follow that X has reasons to love a physiologically exact replacement for Y? Can love's reasons be duplicated? One response to the problem is to suggest that X lacks reasons for loving such a duplicate because the reason-conferring properties of Y cannot be fully duplicated. But a concern, played upon by Derek Parfit, is that this response may result from a failure to take account of the psychological pressures of an actual duplication scenario. In (...) the face of the actual loss of a loved one and the subsequent appearance of a duplicate, how could we resist the inclination to love? Drawing upon duplication scenarios from Parfit and from Stanislaw Lem's Solaris, this paper will argue that there could be reasons for X to come to love a duplicate of Y but that these would not be identical with the reasons that X had (and may still have) to love Y. Nor (in the case of an agent with a normal causal history) could they be reasons for a love that violates the requirement that love is a response to a relationship and therefore takes time to emerge.

Recent developments in biogerontology—the study of the biology of ageing—suggest that it may eventually be possible to intervene in the human ageing process. This, in turn, offers the prospect of significantly postponing the onset of age-related diseases. The biogerontological project, however, has met with strong resistance, especially by deontologists. They consider the act of intervening in the ageing process impermissible on the grounds that it would (most probably) bring about an extended maximum lifespan—a state of affairs that they deem intrinsically (...) bad. In a bid to convince their deontological opponents of the permissibility of this act, proponents of biogerontology invoke an argument which is grounded in the doctrine of double effect. Surprisingly, their argument, which we refer to as the ‘double effect argument’, has gone unnoticed. This article exposes and critically evaluates this ‘double effect argument’. To this end, we first review a series of excerpts from the ethical debate on biogerontology in order to substantiate the presence of double effect reasoning. Next, we attempt to determine the role that the ‘double effect argument’ is meant to fulfil within this debate. Finally, we assess whether the act of intervening in ageing actually can be justified using double effect reasoning. (shrink)

The paper starts with a presentation of the pure happiness theory, i.e. the idea that the quality a person’s life is dependent on one thing only, viz. how happy that person is. To find out whether this type of theory is plausible or not, I examine the standard arguments for and against this theory, including Nozick’s experience machine argument. I then investigate how the theory can be modified in order to avoid the most serious objections. I first examine different types (...) of epistemic modifications of the theory (e.g. the idea that a person’s happiness is more valuable for her if it is based on a correct perception of her own life), and then turn to a number of modifications which all make the value of a person’s happiness depend on whether the evaluative standard on which her happiness is based satisfies certain requirements. In connection with this, I present and defend my own modified version of the happiness theory. (shrink)

This paper presents an argument to the effect that the relation of exact similarity with respect to properties that are supervenient cannot be transitive. The point of departure is that, while a difference in respect of supervenient properties entails a difference in respect of subvenient properties, exact similiarity in respect of supervenient properties is compatible with differences in respect of subvenient properties. It is logically possible that two such sets of differences that each individually is insufficient for a difference as (...) regards the supervenient property together are sufficient for such a supervenient difference. This possibility claim is incompatible with the necessity claim entailed by the transitivity of exact similarity. Several objections to this argument are then considered. (shrink)

George Terzis makes several objections to claims and arguments I advanced in Impartial Reason. I cannot take them all up, but I would like to respond to some, which I shall group into three: whether reasons depend on norms applying to all rational agents; how the unity of agency relates to such norms; and the self-support condition. Since the objections concerning cut most deeply against the central thesis of Impartial Reason, I shall begin with them. Before I do that, however, (...) I should make some preliminary remarks.Impartial Reason offers an internalist theory of reasons, but one that is, I believe, more sensitive to the normative character of reasons than internalist theories usually are.1 A theory of reasons is internalist if it holds that something's being a reason depends somehow on its capacity to affect motivation. Unlike internalist theories that identify reasons with de facto motives, however, IR insists on the normative character of reasons as tending to justify conduct as rational. It does this by holding that a reason to act is something which motivates when appropriately considered. The normative or justificatory weight of reasons, then, is held to derive from a normative ideal of rational consideration. Reasons inherit as justificatory weight the motivational force they would come to have in an ideally rational process of practical reflection. (shrink)

In Morals by Agreement David Gauthier proposes four criteria for classifying a society's advancement toward ‘higher stages of human development.' Significantly, these criteria — material well-being, breadth of opportunity, average life-span, and density of population — do not include as an equally valuable achievement the society's capacity to sustain its standard of living. Nonetheless Gauthier presents three arguments intended to show that a community founded on his distributive theory will view depletionary resource policies as unreasonable and unacceptable. I shall contend (...) that these arguments do not succeed in motivating sustainable rates of resource exploitation. Furthermore, I argue that if truly just and rational resource use policies can be arrived at, such policies could only succeed by employing a conception of property rights substantially different from Gauthier's.

Some of us believe in giving priority to people who are badly off in designing social policies and in acting ourselves to help others. As Thomas Nagel puts it, the badly off should be first in the queue when benefits are distributed. This idea is one way of explaining moral views that are called ‘egalitarian.’ Egalitarian moral views can depend either on the idea of valuing equality itself or on the idea of giving priority to the interests of the badly (...) off. This paper is concerned with the second kind of egalitarianism.The purest form of the idea explains the priority in this way: a benefit for someone badly off can be more important morally, or can have more value, than a benefit of the same size for someone better off. This is to suppose that the priority in question cannot be explained by thinking in utilitarian terms and accepting the principle of diminishing marginal utility. (shrink)

It is now broadly accepted that disability is a concept infused with both descriptive and evaluative meaning, such that invoking the concept of disability necessarily involves making judgements of moral value as well as describing certain facts about individuals. This paper aims to map the complex terrain that shapes our current understandings of disability by outlining five distinct ‘discourses of disability’. It is shown how the similarities and differences between the discourses hinge on different ways of making sense of the (...) descriptive and evaluative dimensions of the concept, and the relationships between these dimensions. The paper concludes by considering the specific implications that these different ways of elucidating the concept of disability might have for the provision of clinical ethics support, both in terms of shaping ethical decision-making relating to people with disabilities and in terms of framing the process of providing clinical ethics support itself.

Abstract:We examine the moral and managerial significance of some empirical studies in cognitive psychology. We suggest that these results may plausibly be interpreted as expressing deontological commitments of experimental subjects, even though psychologists who discuss the results seem to suppose that they show that people are irrational consequentialists. We argue that the plausibility of our interpretation suggests how managers who wish to take seriously entrenched social views on morality might best craft corporate policy on corporate responsibility, and we suggest that (...) the form of argument we employ may be regarded as a kind of appeal to reflective equilibrium.

Abstract:The kind of commitment to moral rules that characterizes effective interaction between persons in among others places, manufacturing and commercial settings is characteristically treated by economists and game theorists as a public good, the securing of which requires the expenditure of scarce resources on surveillance and enforcement mechanisms. Alternatively put, the view is that, characteristically, rational persons cannot voluntarily guide their choices by rules, but can only be goaded into acting in accordance with such rules by the fear of social (...) and formal sanctions. On this way of thinking, rational individuals are condemned to having to settle for the “second-best” results that are thereby implied. This conclusion rests not only on an appeal to a consequentialist perspective, but also a separability principle. Against this, it is argued that consequentialism itself offers a basis for the rejection of the separability principle, and a defense of the thesis that, for a wide range of realistic cases, being disposed to voluntarily guide one’s choice by rules (on the condition that others can be expected to do so as well) is a necessary condition of engaging in rational interaction.Most people do not trust most other people, unmonitored, to honor obligations completely. Because of this they use substantial amounts of resources to specify the details of agreements, and to police them. Use of these resources … could be greatly reduced, if transacting parties would agree to honor the spirit of their agreement and simply shake hands. The resource saving to the two parties combined, from substituting this mode of “enforcing” agreements to those currently used, is clear. Why, then, does not this more efficient mode of transacting drive out the more costly methods through the normal competitive process? … The underlying rationale for this … is that it is privately profitable to engage in some degree of “cheating” on agreements, and to use resources to disguise this fact. — M. W. Reder, “The Place of Ethics in the Theory of Production”. (shrink)

Abstract:Concern for one’s “reputation” has been introduced in recent game theory enabling theorists to demonstrate the rationality of cooperative behavior in certain contexts. And these impressive results have been generalized to a variety of situations studied by students of business and business ethicists. But it is not clear that the notion of reputation employed has much explanatory power once one sees what is meant. I also suggest that there may be some larger lessons about the notion of rationality used by (...) decision theorists. (shrink)

In this quite modestly ambitious essay, I'll generally just assume that, for the most part, our "scientifically informed" commonsense view of the world is true. Just as it is with such unthinking things as planets, plates and, I suppose, plants, too, so it also is with all earthly thinking beings, from people to pigs and pigeons; each occupies a region of space, however large or small, in which all are spatially related to each other. Or, at least, so it is (...) with the bodies of these beings. And, even as each of these ordinary entities extends through some space, so, also, each endures through some time. In line with that, each ordinary entity is at least very largely, and is perhaps entirely, an enduring physical entity (which allows that many might have certain properties that aren't purely physical properties.) Further, each ordinary enduring entity is a physically complex entity: Not only is each composed of parts, but many of these parts, whether or not absolutely all of them, are themselves enduring physical entities, and many of them also are such physically complex continuing entities. When an ordinary entity undergoes a significant change, then, at least generally, this change will involve changes concerning that entity's constituting physical parts, whether it be a rearrangement of (some of) these parts, or a loss of parts, or a gain of parts, or whatever. Often, the entity will still exist even after the change occurs. As we may well suppose, this happens when, from two strokes of an ax, an ordinary log loses just a chip of wood. As we may then say, such a change conforms with the log's "persistence conditions." Somewhat less often, such an ordinary entity undergoes a change that means an end to it: When a bomb's explosion makes our log become just so many widely scattered motes of dust, the log will no longer exist. Such a momentous change doesn't conform with the log's persistence conditions. (shrink)

Suppose that two nations A and B each possess a nuclear arsenal and are rational utility-maximizers. Suppose further that B has some interest in provoking A, possibly by attacking her with nuclear weapons. In the hope of preventing this from happening, A informs B of à conditional intention on her part to retaliate against B with nuclear weapons should B in fact attack A. By doing so A attempts to lower the probability of B's attacking A by increasing B's estimate (...) of the conditional probability of A's retaliating once provoked. Problematic deterrent situations are those in which B prefers to attack A without retaliation, A prefers most of all that she not be attacked, and A prefers an attack-with-no-retaliation scenario to an attack-with-retaliation scenario. Feature is à result of the fact that A prefers to minimize nuclear devastation, i.e., A would herself be worse off retaliating than not retaliating to an attack. Now, if B knows all of this to be the case then A's expression of a conditional intention to retaliate will not in fact deter B from attacking, since A is rational and will not act contrary to her own best interests. B has no reason to fear A's retaliation and therefore B has no reason not to attack. Deterrence, it seems, is an irrational policy among fully rational actors. This is one version of the so-called paradox of deter-rence. If expressing a conditional retaliatory intention is the best way for A to ward off an attack, then the paradox can be strengthened as follows: It is rational for A to intend to act irrationally.

Traditionally, the problem of defeating scepticism about the rationality of morality is that of showing that every morally required act is rationally required. Little or no direct attention has been paid to whether we must also show that it is rational for the agent to have and act from the morally appropriate motive, whatever that may be. This is not to say that philosophers have entirely ignored the issue of motives; a fair number—Kant and Aristotle come to mind—are concerned in (...) part with the kind of motive agents ought to have and from which they ought to act. But the link to scepticism has not been clearly made. At issue is whether scepticism is fully defeated if we show that every morally required act is rationally required, even if we leave it possible that a fully rational person who performs the act just “goes through the motions” in doing so.

Since philosophers began thinking seriously about the moral status of non-human animals, many of the practices we once took for granted have come to be condemned as unjustifiable, among them our reliance on animals as a food source. While the arguments which have been adduced in support of moral vegetarianism invoke quite different moral frameworks, they begin with a common concern for the welfare of animals. In the real world of practising vegetarians, this concern tends to be subordinated to considerations (...) of health or food scarcity. Philosophical vegetarians need not deny, and have not denied, the importance of these further considerations. But among philosophers the case for moral vegetarianism has rested primarily on arguments from animal welfare. (shrink)

A truly Christian bioethics challenges the nature, substance, and application of secular morality, dividing Christians from non-Christians, accenting central moral differences, and providing content-full forthrightly Christian guidance for action. Consequently, Christian bioethics must be framed within the metaphysical and theological commitments of Traditional Christianity so as to provide proper orientation toward God. In contrast, secular bioethicists routinely present themselves as providing a universal bioethics acceptable to all reasonable and rational persons. Yet, such secular bioethicists habitually insert their own biases and (...) prejudices into their moral conclusions, ethical consultations, and political aspirations, without any real justification. As this article explores, the ideologically driven anti-Christian commitments, including commitments to human rights and social justice, embodied within contemporary bioethics routinely illustrate the increasing gap between the traditionally Christian and the devoutly secular, further deepening the culture wars.
