"In this splendidly engaging book, Torbjörn Tännsjö surveys a range of moral problems of killing -- such as capital punishment, euthanasia, abortion, war, and the killing of animals -- through the lenses of three moral theories: deontology, rights theory, and utilitarianism. His main aim is to find the true theory by testing the three candidates' implications against considered intuitions about the problems (and a provisional winner does emerge). But he also aims to reach the truth about the problems. These are ambitious aims but Tännsjö makes impressive progress, which the reader can follow without difficulty, as the writing is lucid and accessible throughout." --Jeff McMahan, White's Professor of Moral Philosophy, University of Oxford "Tännsjö clearly details the salient aspects of each theory. He provides interesting discussions of topics such as the Doctrine of Double Effect, the Principle of Proportionality, together with a useful introduction to Just War Theory. The concise explanation of each dilemma and the practical application of the three theories repeatedly throughout the book appeals, since many students struggle to apply theories to cases and the rigorous repeated application of the three theories could be very instructive. I also enjoyed rethinking familiar ethical dilemmas from a different perspective.
