This course introduces students to essential topics and questions in moral philosophy: How ought we to live our lives? How are right and wrong determined? Are ethical judgments objective or subjective? Are values universal and absolute or culturally relative? What responsibilities do human beings have to one another, to other species, or to the planet? Students will analyze, interpret and evaluate ideas from major schools of ethical thought--including virtue ethics, deontological ethics, and consequentialism--and practice applying theories about ethics to contemporary moral dilemmas.
