Description: Professor Gendler begins with a general introduction to moral theories--what are they and what questions do they answer? Three different moral theories are briefly sketched: virtue theories, deontological theories, and consequentialist theories. Professor Gendler introduces at greater length a particular form of consequentialism—utilitarianism—put forward by John Stuart Mill. A dilemma is posed which appears to challenge Mill's Greatest Happiness Principle: is it morally right for many to live happily at the cost of one person's suffering? This dilemma is illustrated via a short story by Ursula Le Guin, and parallels are drawn between the story and various contemporary scenarios.
