This article argues that existing approaches to programming ethical AI fail to resolve a serious moral-semantic trilemma, generating interpretations of ethical requirements that are either too semantically strict, too semantically flexible, or overly unpredictable. This paper then illustrates the trilemma utilizing a recently proposed ‘general ethical dilemma analyzer,’ GenEth. Finally, it uses empirical evidence to argue that human beings resolve the semantic trilemma using general cognitive and motivational processes involving ‘mental time-travel,’ whereby we simulate different possible pasts and futures. I (...) demonstrate how mental time-travel psychology leads us to resolve the semantic trilemma through a six-step process of interpersonal negotiation and renegotiation, and then conclude by showing how comparative advantages in processing power would plausibly cause AI to use similar processes to solve the semantic trilemma more reliably than we do, leading AI to make better moral-semantic choices than humans do by our very own lights.

A detailed, clear, and comprehensive overview of the current philosophical debate on. The question of when, and under what circumstances, the practice of torture might be justified has received a great deal of attention in the last decade in both academia and in the popular media. Many of these discussions are, however, one-sided with other perspectives either ignored or quickly dismissed with minimal argument. In On the Ethics of Torture, Uwe Steinhoff provides a complete account of the philosophical debate surrounding (...) this highly contentious subject. Steinhoff’s position is that torture is sometimes, under certain narrowly circumscribed conditions, justified, basing his argument on the right to self-defense. His position differs from that of other authors who, using other philosophical justifications, would permit torture under a wider set of conditions. After having given the reader a thorough account of the main arguments for permitting torture under certain circumstances, Steinhoff explains and addresses the many objections that have been raised to employing torture under any circumstances. This is an indispensible work for anyone interested in one of the most controversial subjects of our times. (shrink)
