This course offers an introduction to the basic concepts of critical thinking and propositional logic. The aim is to present students with a balanced survey of inductive (content) and deductive (formal) kinds of arguments. Students will learn about the advantages and disadvantages of each kind of argumentation, thereby gaining a comprehensive vision of the capacities and limitations of rationality in general. The course begins with a discussion of the fundamental principles of argument analysis. Students learn how to distinguish between premises and conclusions, how to recognize arguments from non-arguments, and also gain tools for assessing the strength and cogency of arguments in our everyday language. Students also learn how to identify and fix both formal and informal fallacies. If time permits, propositional logic will take up the last section of the course. Students will become acquainted with truth tables and natural deduction, and will practice translating from natural language into symbolic notation. Throughout the course, emphasis will be placed on the application of logic within our everyday lives, helping students to develop clear thinking skills, while exploring the usefulness of logic for philosophy and theoretical subjects generally.
