The neural basis of the Chorus model has been cast in terms of the visual alphabet theory, but the neural evidence can also be interpreted as supporting a theory of higher level representation in which neurons are responsive to complex 3D stimuli. These neurons, functioning as a population, could also form the basis of a representation such as envisaged by the Chorus model.

In this article, transhumanism is considered to be a quasi-medical ideology that seeks to promote a variety of therapeutic and human-enhancing aims. Moderate conceptions are distinguished from strong conceptions of transhumanism and the strong conceptions were found to be more problematic than the moderate ones. A particular critique of Boström’s defence of transhumanism is presented. Various forms of slippery slope arguments that may be used for and against transhumanism are discussed and one particular criticism, moral arbitrariness, that undermines both weak (...) and strong transhumanism is highlighted.

In this paper, I offer a view beyond that which would narrowly reduce the role of parents in medical decision making to acting as custodians of the best interests of children and toward an account of family authority and family autonomy. As a fundamental social unit, the good of the family is usually appreciated, at least in part, in terms of its ability successfully to instantiate its core moral and cultural understandings as well as to pass on such commitments to (...) future generations. The putative rights of children to expression, information, freedom of thought, conscience, religion, and to freedom of association with others are, in this essay, assessed from the perspective of those conditions necessary for the family to function as a moral community. In so doing, I respond to the move to liberate children from parental authority and to effect the transformation of the family as implied by the United Nations’ "Convention on the Rights of the Child" and the pediatric bioethics it supports.

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)

Truth of x (independently of any description of x) that it is f. A property f which holds of x but is not per se of x is said to hold per accidens of x. The essence of an individual is the sum of its per se properties. We can formulate the following: doctrine a: concrete individuals do not have essences though abstract entities do. Doctrine b: concrete individuals have essences but they do not individuate, whereas abstract entities have essences (...) which do individuate. Assumption i: we shall say that a thing exists insofar as it has an essence. Assumption ii: we shall say that we know a thing when we know what its per se properties are. We argue that plato held doctrine a and aristotle doctrine b (with assumptions i and ii). (edited). (shrink)

To many who develop and use free software, the GNU General Public License represents an embodiment of the meaning of free software. In this paper we examine the definition and meaning of free software in the context of three events surrounding the GNU General Public License. We use a case involving the GPU software project to establish the importance of Freedom 0 in the meaning of free software. We analyze version 3 of the GNU General Public License and conclude that (...) although a credible case can be made that the added restrictions are consistent with the definition of free software, the case requires subtle arguments. Strong arguments against the added restrictions are less subtle, and may therefore be more convincing to many users and developers. We also analyze the Affero General Public License and conclude that it is inconsistent with the definition of free software. (shrink)

Although smallpox was declared eradicated in 1980, there are fears that stocks of the virus manufactured for military purposes by the Soviet Union may have fallen into the hands of “rogue nations” or terrorists. Worries about bioterrorism have thus sparked debate about whether or not the smallpox vaccine, which can be dangerous, should be offered to the general public. Meaningful public debate on this issue requires expert information about the likelihood that the virus will in fact be used as a (...) weapon. Informed voluntary individual decision making, about whether to get vaccinated if vaccine is made available to the public, would similarly require appreciation of the likelihood of attack. Public deliberation and private deliberation thus both require briefing by the intelligence community. (shrink)

The theory of mental models and its computer implementations have led to crucial experiments showing that no standard logic—the sentential calculus and all logics that include it—can underlie human reasoning. The theory replaces the logical concept of validity (the conclusion is true in all cases in which the premises are true) with necessity (conclusions describe no more than possibilities to which the premises refer). Many inferences are both necessary and valid. But experiments show that individuals make necessary inferences that are (...) invalid, e.g., Few people ate steak or sole; therefore, few people ate steak. Other crucial experiments show that individuals reject inferences that are not necessary but valid, e.g., He had the anesthetic or felt pain, but not both; therefore, he had the anesthetic or felt pain, or both. Nothing in logic can justify the rejection of a valid inference: a denial of its conclusion is inconsistent with its premises, and inconsistencies yield valid inferences of any conclusions whatsoever including the one denied. So inconsistencies are catastrophic in logic. In contrast, the model theory treats all inferences as defeasible (nonmonotonic), and inconsistencies have the null model, which yields only the null model in conjunction with any other premises. So inconsistences are local. Which allows truth values in natural languages to be much richer than those that occur in the semantics of standard logics; and individuals verify assertions on the basis of both facts and possibilities that did not occur.

The use of coercive measures in the care for the addicted has changed over the past 20 years. Laws that have adopted the “dangerousness” criterion in order to secure patients’ rights to non-intervention are increasingly subjected to critique as many authors plead for wider dangerousness criteria. One of the most salient moral issues at stake is whether addicts who are at risk of causing danger to themselves should be involuntarily admitted and/or treated. In this article, it is argued that the (...) dilemma between coercion on the one hand and abandonment on the other cannot be analysed without differentiated perspectives on the key notions that are used in these debates. The ambiguity these notions carry within care practice indicates that the conflict between the prevention of danger and respect for autonomy is not as sharp as the legal systems seem to imply. Some coercive measures need not be interpreted as an infringement of autonomy—rather, they should be interpreted as a way to provide good care. (shrink)

Television medical dramas sometimes depict medical professionalism and bioethical issues, but their nature and extent are unclear. The authors systematically analysed the bioethical and professionalism content of one season each of Grey's Anatomy and House M.D., two of the most popular current television medical dramas. The results indicate that these programmes are rife with powerful portrayals of bioethical issues and egregious deviations from the norms of professionalism and contain exemplary depictions of professionalism to a much lesser degree.

The United Nations Educational, Scientific, and Cultural Organization's (UNESCO) Universal Declaration on Bioethics and Human Rights announces a significant array of welfare entitlements—to personal health and health care, medicine, nutrition, water, improved living conditions, environmental protection, and so forth—as well as corresponding governmental duties to provide for such public health measures, though the simple expedient of announcing that such entitlements are “basic human rights.” The Universal Declaration provides no argument for the legitimacy of the sweeping governmental authority, taxation, and regulation (...) to create and impose such “rights.” As this paper explores that some action promotes a purported good, such as “health,” does not thereby make the action morally permissible. Just as there are moral limits on legitimate personal actions, there are also moral limits on legitimate governmental actions to promote purported goods, including health. A core question of any governmental regulation, therefore, is whether it is a legitimate application of moral political authority or an unauthorized act of state coercion. Pace UNESCO's wide-ranging assertions, this paper argues that promoting health only falls within the legitimate authority of governments in very narrowly defined circumstances. As the paper critically explores, at stake are foundational moral and political questions concerning the limits of governmental authority to intervene in the consensual interaction of persons. Imposing such duties on others, including citizens of a state through regulatory activity and taxation, must be justified, nonarbitrary, and demonstrably within the limits of moral political authority. UNESCO's assertions do not meet this burden of proof. (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.

In Book Γ of the Metaphysics Aristotle states and attempts to prove what he calls the basic principle of the science of being as being: the law of non‐contradiction. In this paper I defend an interpretation of his proof, inspired by Elizabeth Anscombe's 1961 essay in ‘Three Philosophers’, though some of its features were remarked on by Lukasiewicz in 1910, according to which Aristotle is proving this principle only for substance predicates, and that it is to be understood as the (...) basic principle of metaphysics rather than of logic. It is the principle that every substance has an essential nature, and if it is of the essential nature of x to be F then it cannot be of the essential nature of x to be not‐F since then x's being F and x's being not‐F would be the same. He puts it by saying that in such a case F and not‐F would ‘signify the same’ for x. Since they do not, x cannot be both. (shrink)

This paper considers the problem that arises when the number of patients who need a resource exceeds the supply. An initial decision-making model is proposed that uses two essential criteria, medical prognosis and the priority of life-threatening situations. The model is then subjected to the criticism that it is grotesque to ignore questions relating to the value of, for example, a productive mother over against an aged recluse, and to treat them as having equal rights to access. It is argued (...) that this criticism need not be an expression of prejudice but may reflect a defendable view in which utilitarian considerations enter into the selection process provided that certain fundamental, or 'deontological' rights are observed for all. In the light of the discussion the model is modified in order to contain both a non-utilitarian feature that stresses the intrinsic importance of all persons, and a utilitarian feature that can allow one, in certain circumstances, to take consequences into account, especially those that follow from the 'irreplaceability' of some people.

This article raises three challenges to Richard McCormick's proportionalism. First, adequately to judge proportionate reason requires the specification of a particular background moral content and metaphysical context. Absent such specification, evaluation of proportionate reason is inherently and deeply ambiguous. Second, to resolve such ambiguity and yet remain Christian, proportionalism must adopt a forthrightly Christian moral content set within a straightforwardly Christian metaphysics. This move will, however, set Christian bioethics off as sectarian—a conclusion McCormick wishes to avoid. Third, even if proportionalism (...) were to adopt a Christian moral content and metaphysics to avoid such ambiguity, its methodology sets aside a key aspect of the Christian life: repentance. Proportionalism does not account for the core reality that repentance plays in one's personal encounter with and knowledge of God. As I will argue, the challenge in part is that moral action cannot be adequately conceptualized, nor can moral theology be properly understood, outside of the authentic practice of the religious life, and repentance is central to that Christian reality.

Couples need to make their wishes explicit if we are to allow postmortem gamete donation.

Doctor and patient meet in a circle of feelings determined by suffering. Sensitivity to the suffering is an axis determining the nature of the doctor and patient relationship. The patient's experience of an illness is individual, private, and very often difficult to describe. But the possibility to understand the suffering of another person comes from the fact that suffering is a universal feeling. We propose to enter the world of patient's experience by writing a letter to a doctor, which would (...) reflect their experiences and expectations towards him. This was the task required for 120 students of the second year of medicine and dentistry education. (shrink)

It is often assumed that the central problem in a medical ethics issue is determining which course of action is morally correct. There are some aspects of ethical issues that will yield to such analysis. However, at the core of important medical moral problems is an irreducible dilemma in which all possible courses of action, including inaction, seem ethically unsatisfactory. When facing these issues ethical behaviour depends upon an individual's understanding and acceptance of this painful dilemma without recourse to external (...) moral authority. (shrink)
