ETH201 is an introductory course in ethics. How should we live? Which course of action is the right one? When and why should we blame ourselves and/or others? We all have and exercise moral opinions; this course is about justifying them. The course begins with some critical reasoning skills, and then explores philosophical strategies for justifying moral beliefs. We will then examine some specific issues of moral and political significance before concluding with psychological mechanisms behind moral attitudes and behaviour.
