This article provides a critical introduction to contractualism as a moral or ethical theory, that is, as a theory of the rightness and wrongness of individual conduct – focusing specifically on the influential 'Kantian' version of contractualism due to T. M. Scanlon. I begin by elucidating the key features of Scanlon's contractualism: justifiability to others; reasonable rejectability; the individualist restriction; and mutual recognition. I then turn to discuss both its appeal and the main objections that have been raised to it (...) – objections concerning our duties to the cognitively limited and impaired, aggregation, demandingness, normativity and explanatory adequacy. I conclude by mentioning some contractualist alternatives to Scanlon's theory. (shrink)

This article addresses a dilemma about autonomous vehicles: how to respond to trade-off scenarios in which all possible responses involve the loss of life but there is a choice about whose life or lives are lost. I consider four options: kill fewer people, protect passengers, equal concern for survival, and recognize everyone’s interests. I solve this dilemma via what I call the new trolley problem, which seeks a rationale for the intuition that it is unethical to kill a smaller number (...) of people to avoid killing a greater number of people based on numbers alone. I argue that killing a smaller number of people to avoid killing a greater number of people based on numbers alone is unethical because it disrespects the humanity of the individuals in the smaller-numbered group. I defend the recognize-everyone’s-interests algorithm, which will probably kill fewer people but will not do so based on numbers alone. (shrink)

The main purpose of the paper is to present a new framework of meta-ethics which I call the Functional Model of Analysis. It presupposes that the most important meta-ethical question is not “What is the meaning of normative words, sentences and what is the ontological fabric of the moral world?” but “What should morality and ethics be for?”. It is a form of meta-ethics that focuses on finding theoretical resources that can be helpful in understanding ongoing ethical debates between disciples (...) of Aristotle, Epicurus, the Stoics, Augustine, Hobbes, utilitarians and Kant, and in building normative ethical theories that can help us to answer normative questions. As an example of such output I will present a formal sketch of Hybrid Function Consequentialism – a normative ethical theory based upon the meta-ethical framework proposed here. (shrink)

In this Commentary, I propose an ethical framework for ethical discussions around the allocation of scarce resources in COVID-19 response. The framework incorporates four principles: beneficence (benefiting people by saving lives or years of life), equality, remedying disadvantage, and recognizing past conduct. I then discuss how the framework interacts with ethical constraints against using people as a mere means and against causing death. The commentary closes by criticizing the equation of deontological ethics with random or first-come, first-served allocation and of (...) allocation that aims to save more lives or years of life with utilitarianism..

The moral permissibility of the intervention in Libya largely turns on two fairly tricky assessments: whether the situation was sufficiently serious at the time the intervention was launched and what the predominant purposes of the intervention were.

This article considers the duty to undertake humanitarian intervention. It first examines the arguments for the duty to intervene and questions the possibility of supererogatory humanitarian intervention. It then considers the leading objections to this duty which, it is argued, are largely unpersuasive. In the final section, the article considers the duty to intervene in the context of the responsibility to protect doctrine, which provides the framework within which debates about humanitarian intervention now in large part occur.

Split liver transplantation (SLT) provides an opportunity to divide a donor liver, offering transplants to two small patients (one or both could be a child) rather than keeping it whole and providing a transplant to a single larger adult patient. In this article, we attempt to address the following question that is identified by the Organ Procurement and Transplant Network and United Network for Organ Sharing: ‘Should a large liver always be split if medically safe?’ This article aims to defend (...) an answer—‘not always’—and clarify under what circumstances SLT is ethically desirable. Our answer will show why a more dynamic approach is needed to the ethics of SLT. First, we discuss a case that does not need a dynamic approach. Then, we explain what is meant by a dynamic approach and why it is needed. (shrink)

Deontic constraints prohibit an agent performing acts of a certain type even when doing so will prevent more instances of that act being performed by others. In this article I show how deontic constraints can be interpreted as either maximizing or non-maximizing rules. I then argue that they should be interpreted as maximizing rules because interpreting them as non-maximizing rules results in a problem with moral advice. Given this conclusion, a strong case can be made that consequentialism provides the best (...) account of deontic constraints. (shrink)

In this article I criticize the non-consequentialist Weighted Lottery (WL) solution to the choice between saving a smaller or a larger group of people. WL aims to avoid what non-consequentialists see as consequentialism's unfair aggregation by giving equal consideration to each individual's claim to be rescued. In so doing, I argue, WL runs into another common objection to consequentialism: it is excessively demanding. WL links the right action with the outcome of a fairly weighted lottery, which means that an agent (...) can only act rightly if s/he has actually run the lottery. In many actual cases, this involves epistemic demands that can be almost impossible to meet. I argue that plausible moral principles cannot make such extreme epistemic demands. (shrink)

I distinguish several arguments Kamm and Scanlon make against Taurek's claim that it is permissible to save smaller groups of people rather than larger. I then argue that none succeeds. This is a companion to my "Saving the Few.".

This chapter presents arguments for two slightly different versions of the thesis that the value of persons is incomparable. Both arguments allege an incompatibility between the demands of a certain kind of practical reasoning and the presuppositions of value comparisons. The significance of these claims is assessed in the context of the “Numbers problem”—the question of whether one morally ought to benefit one group of potential aid recipients rather than another simply because they are greater in number. It is argued (...) that many of the popular approaches to this problem—even ones that avoid the aggregation of personal value—are imperiled by the incomparability theses. -/- . (shrink)
