This book combines the two most common approaches used to introduce students or general readers to ethics: the historical and the applied. Using these approaches, Sterba examines traditional ethical theories and disagreements, exploring Aristotelian, Kantian, and utilitarian ethics, as well as their contemporary defenders. But rather than focusing on formal aspects of these views, Sterba applies the best practical arguments from each of these perspectives to a variety of moral problems, such as sexual harassment, affirmative action, and international terrorism and the second Iraqi war.
