The coefficients of internal consistency and retest reliability had been rarely investigated within the methodology of dream content analysis. Analyzing a dream series of elderly, healthy persons obtained from weekly telephone interviews, the internal consistency of a series of 20 dreams and retests after 4 or 22 weeks, respectively, had been computed. The findings indicate that dream recall and dream length are quite stable, but dream characteristics such as bizarreness and emotional tone underlie large intraindividual fluctuations. In order to obtain (...) reliable measures for these variables which will be important for correlational studies, including waking-life trait measures, one has to obtain as many dreams as possible in a very short time period. Further research is needed to extend the present findings to diary dreams and laboratory dreams. (shrink)

In recent years deflationary accounts of self-deception, under the banner of motivationalism, have proven popular. On these views the deception at work is simply a motivated bias. In contrast, we argue for an account of self-deception that involves more robustly deceptive unconscious processes. These processes are strategic, flexible, and demand some retention of the truth. We offer substantial empirical support for unconscious deceptive processes that run counter to certain philosophical and psychological claims that the unconscious is rigid, ballistic, and of (...) limited cognitive sophistication.

This book uncovers a logical structure that is common to many, if not all, of the kinds posited by scientific taxonomies. Specification relations, such as those holding between determinates and determinables (determination), are central to this logical investigation of kinds. The species–genus relation is a familiar specification relation for substantival kinds, but this book focuses on adjectival kinds—whose instances are properties—instead. Determination relations are then used to structure kinds at the same level of abstraction into property spaces, which in turn (...) leads to a theory for individuating properties (tropes). These determination relations are contrasted with realization relations, the latter being the favored way of understanding the connection between the mental and the physical. Particular attention is given to the distinction between multiple realizability and multiple determination, and it is argued that determination and realization are mutually exclusive. The claim that multiple realizability entails various senses of autonomy is defended from various reductionist challenges. These theories of determination and realization then provide general standards for establishing the autonomy of the special sciences or, conversely, their reduction. (shrink)

Two of the most basic questions regarding self-deception remain unsettled: What do self-deceivers want? What do self-deceivers get? I argue that self-deceivers are motivated by a desire to believe. However, in significant contrast with Alfred Mele’s account of self-deception, I argue that self-deceivers do not satisfy this desire. Instead, the end-state of self-deception is a false higher-order belief. This shows all self-deception to be a failure of self-knowledge.

Causal overdetermination worries arise in a number of domains, but most notably in the philosophy of mind. ln discussions of such worries, alleged examples of causal overdetermination are uniformly viewed as primajzcie problematic. While all alleged cases of overdetermination might be problematic, I aim to show that they are so for different reasons. Examples of causal overdetermination neatly divide into three varieties, corresponding to the connections between the mechanisms and the properties of the causes. Future debates over overdetermination, and mental (...) causation in particular, should pay heed to this distinction. (shrink)

In traditional Frankfurt cases some conditions that make an outcome unavoidable fail to bring about that outcome. These are cases of causal preemption. I defend this interpretation of traditional Frankfurt cases, and its application to free will, against a dilemma raised by various libertarians. But I go on to argue that Frankfurt cases involving gen- uine causal overdetermination are even more effective at achieving the compatibilist’s purposes. Such cases avoid the “flicker of freedom” debate and better display the central disagreement (...) with regard to the Principle of Alternate Possibilities. (shrink)

The properties colored and red stand in a special relation. Namely, red is a determinate of colored, and colored is determinable relative to red. Many other properties are similarly related. The determination relation is an interesting topic of logical investigation in its own right, and the prominent philosophical inquiries into this relation have, accordingly, operated at a high level of abstraction.1 It is time to return to these investigations, not just as a logical amusement, but for the payoffs such investigation (...) can yield in solving some basic metaphysical problems. The goal in what follows is twofold. First, I argue for a novel understanding of the determination relation. Second, this understanding is applied to yield insights into property instance (e.g., trope) individuation, how different property types can share an instance, the relation between property types and property instances, as well as applications to causation (mental causation, in particular).

One version of the Humean Theory of Motivation holds that all actions can be causally explained by reference to a belief–desire pair. Some have argued that pretense presents counter-examples to this principle, as pretense is instead causally explained by a belief-like imagining and a desire-like imagining. We argue against this claim by denying imagination the power of motivation. Still, we allow imagination a role in guiding action as a script . We generalize the script concept to show how things besides (...) imagination can occupy this same role in both pretense and non-pretense actions. The Humean Theory of Motivation should then be modified to cover this script role. (shrink)

This article considers the product of self-deception. Many assume, or argue, that the product of self-deception is a belief. I argue against this being a general truth by outlining some of the ways in which the self-deceived can be deeply conflicted, such that there is no fact of the matter concerning what they believe. These situations are not adequately addressed by many accounts of self-deception. Further, I argue that this task requires going beyond our folk psychological classifications.

Self-deception poses longstanding and fascinating paradoxes. Philosophers have questioned whether, and how, self-deception is even possible; evolutionary theorists have debated whether it is adaptive. For Sigmund Freud self-deception was a fundamental key to understanding the unconscious, and from The Bible to The Great Gatsby literature abounds with characters renowned for their self-deception. But what exactly is self-deception? Why is it so puzzling? How is it performed? And is it harmful? ...

Some collective irrationalities, like epistemically and pragmatically reckless Covid skepticism, are especially dangerous. While we normally have incentives to avoid dangerous beliefs, there are cases in which the danger of a belief is valuable. This is not captured by most accounts of motivated reasoning. I argue that Covid skepticism can function as a costly signal (handicap) so as to more effectively communicate social identity and commitment.

Bernard Williams has argued that, because belief aims at getting the truth right, it is a conceptual truth that we cannot directly will to believe. Manyothers have adopted Williams’ claim that believers necessarily respect truth-conducive reasons and evidence. By presenting increasingly stronger cases, I argue that, on the contrary, believers can quite consciously disregard the demand for truth-conducive reasons and evidence. The irrationality of those who would directly will to believe is not any greater than that displayed by some actual (...) believers. So, our inability to directly will to believe is a contingent truth (at best). (shrink)

Robert Trivers has proposed perhaps the only serious adaptationist account of self-deception—that the primary function of self-deception is to better deceive others. But this account covers only a subset of cases and needs further refinement. A better evolutionary account of self-deception and cognitive biases more generally will more rigorously recognize the various ways in which false beliefs affect both the self and others. This article offers formulas for determining the optimal doxastic orientation, giving special consideration to conflicted self-deception as an (...) alternative to outright self-delusion. A novel taxonomy of self-deception, as it relates to the beliefs held by others, is also presented. While Trivers makes a plausible case for the adaptive value of certain cognitive biases, a more fragmented and nuanced account of the social forces impacting the evolution of self-deception is needed.

Prima facie, there is an incompatibility between God’s alleged omnipotence and impeccability. I argue that this incompat- ibility is more than prima facie. Attempts to avoid this appearance of incompatibility by allowing that there are commonplace states of affairs that an omnipotent being cannot bring about are unsuc- cessful. Instead, we should accept that God is not omnipotent. This is acceptable since it is a mistake to hold that omnipotence is a perfection. God’s moral perfection should be privileged over God’s (...) potency properties—and the same is true of human beings as well. (shrink)

Philosophical accounts of self-deception almost invariably treat it as a phenomenon concerning belief. But this article argues that, in the very same sense that we can be self-deceived about belief, we can be self-deceived about matters that concern our practical identities — e.g., our desires, emotions, values, and lifestyles. Given that our practical identities are at least as important to us as are our beliefs, philosophical accounts of self-deception should accommodate such practical self-deception.

Deflationists reduce self-deception to a motivated bias, eliminating the need for doxastic tension, divided minds, intentions, or even effortful action. While deflationism fits many cases, there are others that demand more robust psychological processes and complexity. We turn to the empirical literature on self-handicapping to find commonplace examples of self-deception with high levels of agential involvement. Many self-handicappers experience non-trivial doubts, engage in strategic and purposive self-deception, and possess knowledge that must remain unconscious for their project to succeed. This occurs (...) with self-handicapping for the sake of self-esteem regulation. Such self-handicapping not only requires self-deception but also furthers it. (shrink)

While the concept of multiple realizability is widely used, it is seldom rigorously characterized. This paper defends a liberal conception of multiple realizability as sameness of type through _any_ differences in the (lower-level) conditions that give rise to instances of that type. This kind of “sameness through difference” is contrasted with another type of asymmetric dependency relation between properties, multiple _specification_. This liberal conception is then defended from objections, and it is augmented by a concept of relativized multiple realizability. The (...) last section presents a survey of the ontological, explanatory, and methodological consequences of this analysis of multiple realizability. (shrink)

People are biased toward beliefs that are welcomed by their in-group. Some beliefs produced by these biases—such as climate change denial and religious belief—can be fruitfully modeled by signaling theory. The idea is that the beliefs function so as to be detected by others and manipulate their behavior, primarily for the benefits that accrue from favorable tribal self-presentation. Signaling theory can explain the etiology, distinctive form, proper function, and alterability of these beliefs.

Beliefs serve at least two broad functions. First, they help us navigate the world. Second, they serve as signals to manipulate others. Philosophers and psychologists have focused on the first function while largely overlooking the second. This article advances a conception of signals and makes a prima facie case for a social signaling function for at least some beliefs. Truth and rational support are often irrelevant to the signaling function. If some beliefs evolved for a signaling function, then we should (...) expect various biases that aid in the manipulation of others. (shrink)

ABSTRACTThis article responds to Glazer’s claim that signals must be perceptible as well as his purported counterexample to my conditions for signaling. I defend a broader sense of signal detection that allows for imperceptible signals. While we disagree over the belief-signaling thesis, Glazer and I have great agreement over the social functions of belief.

Like proper names, demonstratives, and definite descriptions, pronouns have referential uses. These can be 'essentially indexical' in the sense that they cannot be replaced by non-pronominal forms of reference. Here we show that the grammar of pronouns in such occurrences is systematically different from that of other referential expressions, in a way that illuminates the differences in reference in question. We specifically illustrate, in the domain of Romance clitics and pronouns, a hierarchy of referentiality, as related to the topology of (...) the grammatical phase. Our explanation is based on extending the 'Topological Mapping Hypotheses' of Longobardi and Sheehan & Hinzen. The extended topology covers the full range of interpretations, from purely predicative to quantificational, to referential and deictic. Along this scale, grammatical complexity increases, and none of these forms of reference is lexical. This provides evidence for the foundational conclusion that the source of essential indexicality is grammatical rather than lexical, semantic or pragmatic. (shrink)

The variety DMM of De Morgan monoids has just four minimal subvarieties. The join-irreducible covers of these atoms in the subvariety lattice of DMM are investigated. One of the two atoms consisting of idempotent algebras has no such cover; the other has just one. The remaining two atoms lack nontrivial idempotent members. They are generated, respectively, by 4-element De Morgan monoids C4 and D4, where C4 is the only nontrivial 0-generated algebra onto which finitely subdirectly irreducible De Morgan monoids may (...) be mapped by noninjective homomorphisms. The homomorphic preimages of C4 within DMM constitute a proper quasivariety, which is shown to have a largest subvariety U. The covers of the variety within U are revealed here. There are just ten of them. In exactly six of these ten varieties, all nontrivial members have C4 as a retract. In the varietal join of those six classes, every subquasivariety is a variety—in fact, every finite subdirectly irreducible algebra is projective. Beyond U, all covers of [or of ] within DMM are discriminator varieties. Of these, we identify infinitely many that are finitely generated, and some that are not. We also prove that there are just 68 minimal quasivarieties of De Morgan monoids. (shrink)

This careful and engaging introduction to Aristotle equips readers of ancient philosophy and classics with an intellectual map that will guide their further exploration within the terrains of Aristotelian philosophy and logic. The book does not seek to provide a verdict or to persuade the reader of the usefulness of Aristotle's ideas. Instead it offers a comprehensive introduction to key philosophical areas while situating the reader within the ongoing intellectual debates on Aristotle's significance and relevance. Crowley's book allows an overview (...) of Aristotle's contributions and includes discussions on the Organon, the epitome of his logical treatises, his works on biology, nature and causation, metaphysics, citizenship, ethics and eudaimonia. The book is a valuable tool for readers interested in becoming acquainted with the work of Aristotle but most importantly for those who are keen to understand his many interpretations. (shrink)

Background: Patients in clinical settings are not lonely islands; they have relatives who play a more or less active role in their lives. Objectives: The purpose of this article is to elucidate the ethical challenges nursing staff encounter with patients’ next of kin and to discuss how these challenges affect clinical practice. Research design: The study is based on data collected from ethical group discussions among nursing staff in a nursing home. The discussions took place in 2011 and 2012. The (...) data were analysed and interpreted by using hermeneutic methodology. Ethical considerations: All the data have been anonymised and handled with confidentiality. Written informed consent was obtained from all participants. Findings: Ethical challenges relating to patients’ next of kin were found to be an issue frequently discussed in the groups. Our findings indicate that next of kin have different characteristics, categorised as ‘the professionals’ and ‘the shadows’. In this article, we will describe the next of kin’s characteristics and the ethical challenges and practical implications that nursing staff experience in this connection. Discussion: We will discuss the findings in the light of the four basic principles of medical ethics and propose interventions to help nurses manage ethical challenges related to next of kin. Conclusion: The study reveals the need to enhance nursing staffs’ communicative and ethical skills on an individual level, but most importantly, to establish routines in clinical settings for informing and following up next of kin in a systematic and structured way.

The term “mental illness” implies that persons with such illnesses are more likely to be dangerous to themselves and/or others than are persons without such illnesses. This is the source of the psychiatrist’s traditional social obligation to control “harm to self and/or others,” that is, suicide and crime. The ethical dilemmas of psychiatry cannot be resolved as long as the contradictory functions of healing persons and protecting society are united in a single discipline.Life is full of dangers. Our highly developed (...) consciousness makes us, of all living forms in the universe, the most keenly aware of, and the most adept at protecting ourselves from, dangers. Magic and religion are mankind’s earliest warning systems. Science arrived on the scene only about 400 years ago, and scientific medicine only 200 years ago. Some time ago I suggested that “formerly, when religion was strong and science weak, men mistook magic for medicine; now, when science is strong and religion weak, men mistake medicine for magic”.1We flatter and deceive ourselves if we believe that we have outgrown the apotropaic use of language .Many people derive comfort from magical objects , and virtually everyone finds reassurance in magical words . The classic example of an apotropaic is the word “abracadabra,” which The American Heritage Dictionary of the English Language defines as “a magical charm or incantation having the power to ward off disease or disaster”. In the ancient world, abracadabra was a magic word, the letters of which were arranged in an inverted pyramid and worn as an amulet around the neck to protect the wearer against disease or trouble. One fewer letter appeared in each line of the pyramid, until only the letter “a” remained to form the vertex of the triangle. As …. (shrink)

According to much modern social psychology, behavioural economics and common sense, people's actions and beliefs are frequently the result of rapid intuitive thought rather than careful deliberation. Richard Thaler and Cass Sunstein, in their influential book, Nudge, synthesised the literature and used it as the basis for numerous policy ideas.1 Not least, they gave the word ‘nudge’ as a handy term to apply to all sorts of ways of taking advantage of people's psychological quirks without coercing or bribing them. But (...) while Nudge was long on ideas and enthusiasm, it was short on conceptual clarity. The idea of a nudge was inconsistent with some of the policies Thaler and Sunstein endorsed and their account of nudging's relation to freedom and paternalism was flawed.In Salvaging the concept of nudge, Yashar Saghai acts as a friendly critic who thinks nudging has plenty to offer the policy world but sees that it needs both conceptual clarity and ethical defence.2 He wants to show how some of ways of taking advantage of people's psychology could leave them as free as before and he is especially concerned with what I would describe as a question of manipulation: ….

Accepted quantum description is stochastic, yet history is nonstochastic, i.e., not representable by a probability distribution. Therefore ordinary quantum mechanics is unsuited to describe history. This is a limitation of the accepted quantum theory, rather than a failing of mechanics in general. To remove the limitation, it would be desirable to find a form of quantum mechanics that describes the future stochastically and the past nonstochastically. For this purpose it proves sufficient to introduce into quantum mechanics, by means of a (...) perfected formal correspondence, certain analogs of the classical initial-condition constants. Through the restoration of such parameters at the quantum level one accomplishes a natural accommodation of time anisotropy, wave-function reduction, and “event” description by quantum mechanical equations of motion alone, without the need for extra postulates (e.g., a projection postulate). This requires a complete restructuring of quantum measurement theory. (shrink)

An interpretation is offered of Thrasymachus' account of the nature of justice and just action in book I of the 'Republic' which is internally consistent throughout on all important points. Just action is not defined in terms of its practical consequences, as many commentators assume, but rather in terms of its logical consequences 'vis-a-vis' just agents. When one man acts justly towards another, the performance of the just act renders the just agent vulnerable to unfair or unjust exploitation by those (...) with whom he deals. The "strong man", in Thrasymachus' sense, would thus never be a just man. It is argued that Socrates addresses himself to this position, but that, while the textual Thrasymachus is silenced, Socrates' best arguments are, in fact, inadequate to refute Thrasymachus.

Superstring theory is an extension of conventional quantum field theory that allows for stringlike and branelike material objects besides pointlike particles. The basic foundations on which the theory is built are amazingly shaky, and, equally amazingly, it seems to be this lack of solid foundations to which the theory owes its strength. We emphasize that such a situation is legitimate only in the development phases of a new doctrine. Eventually, a more solidly founded structure must be sought.Although it is advertised (...) as a “candidate theory of quantum gravity”, we claim that string theory may not be exactly that. Rather, just like quantum field theory itself, it is a general mathematical framework for a class of theories. Its major flaw could be that it still embraces a Copenhagen view on the relation between quantum mechanics and reality, while any “theory of everything”, that is, a theory for the entire cosmos, should do better than that.

It is commonly held that respect for autonomy is one of the most important principles in medical ethics. However, there are a number of interpretations as to what that respect actually entails in practice and a number of constraints have been suggested even on our self-regarding choices. These limits are often justified in the name of autonomy. In this paper, it is argued that these different interpretations can be explained and understood by looking at the discussion from the viewpoints of (...) positive and negative liberty and the various notions of a “person” that lay beneath. It will be shown how all the appeals to positive liberty presuppose a particular value system and are therefore problematic in multicultural societies. (shrink)

[T. M. Scanlon] It is clearly impermissible to kill one person because his organs can be used to save five others who are in need of transplants. It has seemed to many that the explanation for this lies in the fact that in such cases we would be intending the death of the person whom we killed, or failed to save. What makes these actions impermissible, however, is not the agent's intention but rather the fact that the benefit envisaged does (...) not justify an exception to the prohibition against killing or the requirement to give aid. The difference between this explanation and one appealing to intention is easily overlooked if one fails to distinguish between the prospective use of a moral principle to guide action and its retrospective use to appraise the way an agent governed him or herself. Even if this explanation is accepted, however, it remains an open question whether and how an agent's intention may be relevant to the permissibility of actions in other cases. \\\ [Jonathan Dancy] My first four sections concentrate on the second section of Professor Scanlon's contribution, where he lays out his conception of moral principles and of the role they play in theory and practice. I will raise questions on the following issues: 1. Scanlon's initial introduction of the notion of a principle. 2. His rejection of the standard view that principles are concerned with the forbidding, permitting and requiring of actions. 3. His rejection of pro tanto conceptions of principles in favour of a conception of them as conclusive. 4. The resulting account of what it is for a principle to face and survive exceptions. Scanlon's discussion of these matters here both appeals to and is in some respects more detailed than the relevant section of his recent What We Owe to Each Other. The topic is interesting both for the role played by principles in Scanlon's present discussion of intention and permissibility, and more generally because of his account of wrongness: an act is wrong iff it is ruled out by principles that nobody could reasonably reject. The remainder of my contribution is concerned with the ostensible focus of IP, namely the relevance of agent-intentions to the permissibility of what is done. (shrink)

Philosophers and psychologists generally hold that, in light of the empirical data, a subject lacks infallible access to her own mental states. However, while subjects certainly are fallible in some ways, I show that the data fails to discredit that a subject has infallible access to her own occurrent thoughts and judgments. This is argued, first, by revisiting the empirical studies, and carefully scrutinizing what is shown exactly. Second, I argue that if the data were interpreted to rule out all (...) such infallibility, the relevant psychological studies would be self-effacing. For they adopt a methodology where a subject is simply presumed to know her own second-order thoughts and judgments--as if she were infallible about them. After all, what she expresses as her second-order judgment is trusted as accurate without independent evidence — even though such judgments often misrepresent the subject’s first-order states. The upshot is that such studies do not discredit all infallibility hypotheses regarding self-attributions of occurrent states. (shrink)

This chapter examines the philosophy of T. H. Green, the initial leading figure among the absolute idealists who dominated British philosophy in the late 19th century. Green sought to establish that the existence and nature of human beings, especially of the human mind, was not susceptible of a purely empirical or scientific explanation. He claimed that the only possible explanation involved reference to the existence of an Eternal Consciousness, which was gradually realizing itself in the temporal world, more especially in (...) the life of human beings. Further issues in his philosophy are examined, such as that things count as real only if they are in unchanging relations to each other, the difference between negative and positive freedom, the nature of moral choice, the superiority of a virtue ethic to a utilitarian one.

In social cognition, knowledge-based validation of information is usually regarded as relying on strategic and resource-demanding processes. Research on language comprehension, in contrast, suggests that validation processes are involved in the construction of a referential representation of the communicated information. This view implies that individuals can use their knowledge to validate incoming information in a routine and efficient manner. Consistent with this idea, Experiments 1 and 2 demonstrated that individuals are able to reject false assertions efficiently when they have validity-relevant (...) beliefs. Validation processes were carried out routinely even when individuals were put under additional cognitive load during comprehension. Experiment 3 demonstrated that the rejection of false information occurs automatically and interferes with affirmative responses in a nonsemantic task. Experiment 4 also revealed complementary interference effects of true information with negative responses in a nonsemantic task. These results suggest the existence of fast and efficient validation processes that protect mental representations from being contaminated by false and inaccurate information. (shrink)

In this paper I propose a solution to the qualitative version of David Miller's verisimilitude reversal argument. Miller (1974) shows that verisimilitude rankings are relative to language choice and hence, are not objective. My solution stems from a reply to an earlier solution proposed by Eric Barnes (1991). Barnes argues that the verisimilitude reversal problem can be solved by revealing an epistemic dimension. I show that Miller's problem cannot be solved by side-stepping foundational metaphysical claims as his epistemic solution suggests. (...) Rather, a substantive metaphysical basis grounds identity relations among properties. The problem of verisimilitude cannot be solved without embracing the fundamental metaphysical distinctions between basic and composite properties that ground the relationship of partial identity among properties.

I argue that Open Theism leads to a retreat from ascribing to God ‘complete omniscience’. Having surrendered this ground, the Open Theist cannot but retreat from ascribing to God complete omnipotence; the Open Theist must admit that God might perform actions which He reasonably expected would meet certain descriptions but which nevertheless do not do so. This then makes whatever goodness (in the sense of beneficence, not just benevolence) God has a matter of luck. Open Theism is committed to a (...) partially ignorant God, one who is subject to the vagaries of luck for the efficacy of at least some of His actions and for His goodness. (shrink)

Some philosophers have thought that life could only be meaningful if there is no God. For Sartre and Nagel, for example, a God of the traditional classical theistic sort would constrain our powers of self-creative autonomy in ways that would severely detract from the meaning of our lives, possibly even evacuate our lives of all meaning. Some philosophers, by contrast, have thought that life could only be meaningful if there is a God. God and the Meanings of Life is interested (...) in exploring the truth in both these schools of thought, seeking to discover what God could and couldn't do to make life meaningful (as well as what he would and wouldn't do). Mawson espouses a version of the 'amalgam' or 'pluralism' thesis about the issue of life's meaning – in essence, that there are a number of different legitimate meanings of 'meaning' (and indeed 'life') in the question of life's meaning. According to Mawson, God, were he to exist, would help make life meaningful in some of these senses and hinder in some others. He argues that whilst there could be meaning in a Godless universe, there could be other sorts of meaning in a Godly one and that these would be deeper. (shrink)

Professor Benhabib seeks to rely upon discourse theory to ground a `right to membership' — a right of immigrants to seek and be granted naturalization. The effort is unpersuasive because discourse theory cannot provide an answer to the fundamental question of who should participate in the conversation that would establish a right to membership, nor is it clear that persons freely and equally discussing membership rules would reach the normative conclusions that Benhabib defends. Protection of the `rights of others' might (...) be better secured by arguing from human rights principles that guarantee rights to all residents — citizens and immigrants — than by arguing for a right to membership.

My purpose in what follows is not so much to defend the basic principle of utilitarianism as to indicate the form of it which seems most promising as a basic moral and political position. I shall take the principle of utility as offering a criterion for two different sorts of evaluation: first, the merits of acts of government, social policies, and social institutions, and secondly, the ultimate moral evaluation of the actions of individuals. I do not take it as implying (...) that the individual should live his life on the basis of constant evaluations of this sort. For there are different levels of decision making each with its appropriate criteria. For example, we each inevitably make many of our decisions from the point of view of our own personal self-fulfilment and this cannot regularly take a directly utilitarian form, nor should the utilitarian want it to do so. His claim is at most that we should sometimes review our life from the point of view of a kind of impersonal moral truth of a universalistic utilitarian character. (shrink)

There are many ways of enhancing human performance. For military aviation in general, and for spaceflight in particular, the most important tools are selection, training, equipment, pharmacology, and surgery. In the future, genetic manipulation may be feasible. For each of these tools, the specific modalities available range from the ethically acceptable to the ethically unacceptable. Even when someone consents to a particular procedure to enhance performance, the action may be ethically unacceptable to society as a whole and the burden of (...) risk for the individual may be too great. In addition, there are several characteristics that define the quality and the acceptability of the consent. Each method of enhancing performance will be examined in the context of the principles of medical ethics in a western society: autonomy, non-maleficence, beneficence, and justice. The aim is to draw the attention of aeromedical practitioners to the complexities of ethical dilemmas such as this particular one in order to help them to develop a morally justifiable code of practice that balances society’s needs against individual ambitions and corporate goals.
