Course Description

Academic Year 2023-2024 • Grade 10 and above • Philosophy Sequence

For reference only; see current year course listing for course availability and details.


This course introduces the discipline of philosophy through examination of logical reasoning. Like many common activities, reasoning raises philosophical questions. The course begins by discussing the difference between valid and invalid deductive arguments as reflected in elementary logic. The bulk of the course looks at examples of reasoning in the fields of practical reasoning and ethics, progressing to law, politics, and theology. Usually we analyze the reasoning in a recent United States Supreme Court opinion. Some common themes emerge. In every field, reasoning cannot begin unless certain fundamental premises are accepted. How do philosophers approach the question of how to choose among competing interests and desires? What is distinctive about scientific reasoning? Why is murder wrong? What premises and forms of argument are used in legal reasoning? Can we discern theological reasoning in the books of the Bible? Towards the middle and end of the course, students will prepare papers analyzing instances of sophisticated reasoning chosen by the instructor.
