In this paper, I address the question whether drones, which may soon possess the ability to make autonomous choices, should be allowed to make life-and-death decisions and act on them. To this end, I examine an argument proposed by Rob Sparrow, who dismisses the ethicality of what he calls “killer robots”. If successful, his conclusion would extend to the use of what I call autonomous killer drones, which are special kinds of killer robots. In Sparrow’s reasoning, considerations of responsibility occupy centre stage. Though I reject his argument, I agree both with Sparrow’s conclusion and with his basic contention that the idea of responsibility should play an important role in the investigation of the problem at hand. Therefore, I propose a different argument to show that we should not allow autonomous robots and more specifically autonomous drones to make life-and-death decisions. This argument also invokes the concept of responsibility. But it does so in a way that is different from Sparrow’s use and is congenial to an account of responsibility that I favour. It assumes the simple principle that morally significant choices should only be made by subjects who are capable of responsibility, which can be reconciled both with a deontological and a consequentialist view of morality. Since killer robots, and in particular autonomous killer drones, seem to lack that capability, it follows that they should not be entrusted to make life-and-death decisions and act on them.

In normative ethics there has been a long-standing debate between consequentialists and deontologists. To settle this dispute moral theorists have often used a selective approach. They have focused on particular aspects of our moral practice and have teased out what consequentialists and deontologists have to say about it. One of the focal points of this debate has been the morality of promising. In this paper I review arguments on both sides and examine whether consequentialists or deontologists offer us a more plausible account of promissory obligation. My conclusion is negative. Given the arguments on the table, I argue, we should conclude that the debate is in a stalemate. It is, therefore, hard to see how the issue of promissory obligation could help us choose between consequentialism and deontology.

This book argues that critics of consequentialism have not been able to make a successful and comprehensive case against all versions of consequentialism because they have been using the wrong methodology. This methodology relies on the crucial assumption that consequentialist theories share a defining characteristic. This text interprets consequentialism, instead, as a family resemblance term. On that basis, it argues quite an ambitions claim, viz. that all versions of consequentialism should be rejected, including those that have been created in response to conventional criticisms. The book covers a number of classic themes in normative ethics, metaethics and, particularly, ethical methodology and also touches upon certain aspects of experimental moral philosophy. It is written in clear language and is analytic in its argumentative style. As such, the book should appeal to students, graduate students as well as professional academics with an interest in analytic moral philosophy.

The theme of this issue of the St. Gallen Business Review is "Harmony". For this reason, we would like to discuss whether two aspects of our life- world are in harmony, namely economic optimization and morality. What is the relation between them? According to a widely shared view, which is one aspect of the doctrine of "mainstream economics", the functioning of an economic system does not require moral behaviour on the part of the individual economic agent. In what follows, we will try to convince you that this is false. If all economic agents – managers, employees, bankers, consumers and so on – were purely self-interested, as mainstream economics assumes, our economic practice would fail. There are various reasons for this. Here we will focus on one of them, namely the pivotal role of interpersonal communication.
