RESUMO

The European Court of Justice's recent ruling that the new techniques for crop development are to be considered as genetically modified organisms under the European Union's regulations exacerbates the need for a critical evaluation of those regulations. The paper analyzes the regulation from the perspective of moral and political philosophy. It considers whether influential arguments for restrictions of genetically modified organisms provide cogent justifications for the policies that are in place, in particular a pre-release authorization requirement, mandatory labelling, and de facto bans (in the form of withholding or opting out of authorizations). It is argued that arguments pertaining to risk can justify some form of pre-release authorization scheme, although not necessarily the current one, but that neither de facto bans nor mandatory labelling can be justified by reference to common arguments concerning naturalness, agricultural policy (in particular the promotion of organic farming), socio-economic effects, or consumers' right to choose.

RESUMO

The domestication of new crops would promote agricultural diversity and could provide a solution to many of the problems associated with intensive agriculture. We suggest here that genome editing can be used as a new tool by breeders to accelerate the domestication of semi-domesticated or even wild plants, building a more varied foundation for the sustainable provision of food and fodder in the future. We examine the feasibility of such plants from biological, social, ethical, economic, and legal perspectives.

RESUMO

Informed consent is considered by many to be a moral imperative in medical research. However, it is increasingly acknowledged that in many actual instances of consent to participation in medical research, participants do not employ the provided information in their decision to consent, but rather consent based on the trust they hold in the researcher or research enterprise. In this article we explore whether trust-based consent is morally inferior to information-based consent. We analyse the moral values essential to valid consent - autonomy, voluntariness, non-manipulation, and non-exploitation - and assess whether these values are less protected and promoted by consent based on trust than they are by consent based on information. We find that this is not the case, and thus conclude that trust-based consent if not morally inferior to information-based consent.

RESUMO

Organic farming is based on the concept of working 'with nature' instead of against it; however, compared with conventional farming, organic farming reportedly has lower productivity. Ideally, the goal should be to narrow this yield gap. In this review, we specifically discuss the feasibility of new breeding techniques (NBTs) for rewilding, a process involving the reintroduction of properties from the wild relatives of crops, as a method to close the productivity gap. The most efficient methods of rewilding are based on modern biotechnology techniques, which have yet to be embraced by the organic farming movement. Thus, the question arises of whether the adoption of such methods is feasible, not only from a technological perspective, but also from conceptual, socioeconomic, ethical, and regulatory perspectives.

RESUMO

Sustainable agriculture in response to increasing demands for food depends on development of high-yielding crops with high nutritional value that require minimal intervention during growth. To date, the focus has been on changing plants by introducing genes that impart new properties, which the plants and their ancestors never possessed. By contrast, we suggest another potentially beneficial and perhaps less controversial strategy that modern plant biotechnology may adopt. This approach, which broadens earlier approaches to reverse breeding, aims to furnish crops with lost properties that their ancestors once possessed in order to tolerate adverse environmental conditions. What molecular techniques are available for implementing such rewilding? Are the strategies legally, socially, economically, and ethically feasible? These are the questions addressed in this review.

RESUMO

Subjective probabilities play a significant role in the assessment of evidence: in other words, our background knowledge, or pre-trial beliefs, cannot be set aside when new evidence is being evaluated. Focusing on homeopathy, this paper investigates the nature of pre-trial beliefs in clinical trials. It asks whether pre-trial beliefs of the sort normally held only by those who are sympathetic to homeopathy can legitimately be disregarded in those trials. The paper addresses several surprisingly unsuccessful attempts to provide a satisfactory justification for ignoring the pre-trial beliefs of the homeopathic community. The ensuing diagnosis of the difficulties here emphasizes that the reason the arguments for choosing the pre-trial beliefs of the conventional community seem insufficient is not the arguments per se. It is rather that there is no cogent argument for choosing the conventional stance which would at the same time rationally persuade a member of the homeopathic community. The paper concludes that, once we understand that this is the predicament, there is no genuine reason to doubt the reasoning that leads us to reject the pre-trial beliefs of the homeopathic community.

RESUMO

In this article we explore the role evidence ought to play in complementary and alternative medicine (CAM). First, we consider the claim that evidence in the form of randomized controlled trials (RCTs) cannot be obtained for CAMs. Second, we consider various claims to the effect that there are ways of obtaining evidence that do not make use of RCTs. We argue that there is no good reason why CAM should be exempted from the general requirement that treatments undergo evaluation by RCT. Third, we consider two implications for health care policy. First, many activities in conventional medicine have never been rigorously evaluated and are widely in use nonetheless. We argue that this fails to provide a reason for exempting CAM from a demand for evidence. Second, CAM use may be compared to a choice of lifestyle, and this has a significant impact on which requirements of evidence can reasonably be imposed.

RESUMO

In this survey we have investigated the experiences and attitudes of Danish physicians regarding end-of-life decisions. Most respondents have made decisions that involve hastening the death of a patient, and almost all find it acceptable to do so. Such decisions are made more often, and considered ethically more acceptable, with the informed consent of the patient than without. But both non-resuscitation decisions, and decisions to provide pain relief in doses that will shorten the patient's life, have been made and found acceptable by at least 50% of the respondents, even when there is no informed consent. Furthermore, 12% have doubled morphine dosages with fixed intervals, thus providing doses substantially higher than that necessary to control pain, without the informed consent of the patient. Two percent have helped in assisted suicide, and 5% have administered a lethal injection at the patient's request. Respectively 37% and 34% find these last two practices ethically acceptable. Amongst those that do not find them acceptable, the most important reasons to be opposed are, the doctrine of double effect, the doctrine of doing and allowing, and the view that human life is sacred. Amongst supporters, the most important reasons mentioned are, that the patient's right to self-determination should be respected, the view that a patient should not be forced to suffer, and the view that the patient has a right to be helped to a dignified death.

RESUMO

For a distribution of health care resources to be fair, it should consider the consequences for the whole lives of the affected persons and not just how badly off they are at the present moment. Since, other things being equal, a person is worse off if he dies young than if he dies old, it is fair to give scarce vital health care resources to young rather than to old persons. In the paper this ageist view is restated and defended against a number of objections raised by John Harris. According to Harris' so-called anti-ageist argument the only relevant consideration in the distribution of vital health care resources is people's desire to go on living. On reflection, this is highly counterintuitive. Instead, it is argued that both present desires to go on living and possible future happiness should weigh together with considerations of fairness. Both fairness and possible future happiness will in most cases speak in favour of saving the young before the old. A number of other problems for the ageist view are discussed, and solutions are suggested.

RESUMO

... We can therefore conclude that either we should go for equality; and in that case QALYs are unfair because they haven't got enough of an ageist bias. Or we should accept consequentialism; and in that case QALYs have just the right sort of ageist bias. No plausible case can, however, be made for the claim that QALYs have an unfair bias against old people. Other things being equal we ought when distributing resources essential for survival favour the young. This ethical claim can be supported both by reference to equality (the life-time-view) and by reference to consequentialism (and the premises that resources generally will be more useful when given to young people).
