This study investigates the link between personal well-being and per capita greenhouse gas emissions by considering a panel data methodological approach. The empirical findings illustrate that there is a significant effect of those emissions on personal well-being through the aggregate country sample. A robust finding is that similar results hold across regional samples, with the strongest effect being displayed in the case of the European regional component. The empirical findings are expected to carry important implications for consumers, corporations, and economic policy makers who all must take explicitly into consideration the impact of their economic decisions on the sustainability of economic growth plans.  相似文献

Many studies have linked audiovisual entertainment to hedonia. Recently, also to eudaimonic happiness. The Eudaimonic Spectator Questionnaire is proposed as a new tool to explore eudaimonic motivations that are linked to the consumption of audiovisual entertainment. The new questionnaire groups these eudaimonic motivations into two factors: the cultivation of cognitiveintellectual growth and socialemotional growth. Once the consistency and reliability of the questionnaire was tested, we observed statistically significant differences between fans and non-fan spectators; these differences were observed in both factors. The results indicated that being a fan is associated with the cultivation of human virtues and character strengths.  相似文献

Cultured meat, like any new technology, raises inevitable ethical issues. For example, on animal ethics grounds, it may be argued that reformed livestock farming in which animals’ lives are worth living constitutes a better alternative than cultured meat, which, along with veganism, implies the extinction of farm animals. Another ethical argument is that, just as we would undermine human dignity by producing and consuming meat that is grown from human cells, eating meat that is grown from nonhuman animal cells would violate animal dignity because it is a way to create an us and them, which would make veganism the only ethical option. The present study challenges this argument. First, I examine the fundamental issue of whether cultured meat provides such an attack on animal dignity. The second issue is whether, assuming that it is true that cultured meat undermines animal dignity, it would be acceptable to reject cultured meat even though this implies sacrificing nonhuman animals.  相似文献

I challenge the common picture of the “Standard Story” of Action as a neutral account of action within which debates in normative ethics can take place. I unpack three commitments that are implicit in the Standard Story, and demonstrate that these commitments together entail a teleological conception of reasons, upon which all reasons to act are reasons to bring about states of affairs. Such a conception of reasons, in turn, supports a consequentialist framework for the evaluation of action, upon which the normative status of actions is properly determined through appeal to rankings of states of affairs as better and worse. This covert support for consequentialism from the theory of action, I argue, has had a distorting effect on debates in normative ethics. I then present challenges to each of these three commitments, a challenge to the first commitment by T.M. Scanlon, a challenge to the second by recent interpreters of Anscombe, and a new challenge to the third commitment that requires only minimal and prima facie plausible modifications to the Standard Story. The success of any one of the challenges, I demonstrate, is sufficient to block support from the theory of action for the teleological conception of reasons and the consequentialist evaluative framework. I close by demonstrating the pivotal role that such arguments grounded in the theory of action play in the current debate between evaluator-relative consequentialists and their critics.  相似文献

Keith Lehrer has been publishing on free will and compatiblism since 1960. Our concern here is to present an account of the development on his work on the subject.  相似文献

Neo-Kantian accounts which try to ground morality in the necessary requirements of agency face the problem of “bad action”. The most prominent example is Christine Korsgaard’s version of constitutivism that considers the categorical imperative to be indispensable for an agent’s self-constitution. In my paper I will argue that a constitutive account can solve the problem of bad action by applying the distinction between constitutive and regulative rules to the categorical imperative. The result is that an autonomous agent can violate the categorical imperative in so far as it amounts to a regulative rule of morality; however, an agent cannot call into question the categorical imperative as a constitutive rule of the practice of morality without losing her or his identity as a moral agent. The paper then compares this approach to bad action with the one Korsgaard provides and outlines also a new way of grounding the categorical imperative.  相似文献

According to recent approaches in the philosophy of medicine, biomedicine should be replaced or complemented by a humanistic medical model. Two humanistic approaches, narrative medicine and the phenomenology of medicine, have grown particularly popular in recent decades. This paper first suggests that these humanistic criticisms of biomedicine are insufficient. A central problem is that both approaches seem to offer a straw man definition of biomedicine. It then argues that the subsequent definition of humanism found in these approaches is problematically reduced to a compassionate or psychological understanding. My main claims are that humanism cannot be sought in the patient–physician relationship alone and that a broad definition of medicine should help to revisit humanism. With this end in view, I defend what I call an outcomes-oriented approach to humanistic medicine, where humanism is set upon the capacity for a health system to produce good health outcomes.  相似文献

Although much has been written on the dead-donor rule (DDR) in the last twenty-five years, scant attention has been paid to how it should be formulated, what its rationale is, and why it was accepted. The DDR can be formulated in terms of either a Don’t Kill rule or a Death Requirement, the former being historically rooted in absolutist ethics and the latter in a prudential policy aimed at securing trust in the transplant enterprise. I contend that the moral core of the rule is the Don’t Kill rule, not the Death Requirement. This, I show, is how the DDR was understood by the transplanters of the 1960s, who sought to conform their practices to their ethics—unlike today’s critics of the DDR, who rethink their ethics in a question-begging fashion to accommodate their practices. A better discussion of the ethics of killing is needed to move the debate forward.  相似文献
