The article discusses how philosophy can be taught in classrooms by actively engaging in philosophical exercises. These exercises help students develop skills like analyzing, critiquing, and reflecting on philosophical concepts. The goal is to learn philosophy by actually doing philosophy, rather than just memorizing facts. Different exercises, such as writing essays, role-playing, and debates, can be used to encourage students to think critically and construct their own beliefs. The researchers classify these exercises into three approaches to truth-finding: connective truth-finding through communication, test-based truth-finding, and community of philosophical inquiry. By using these exercises, students can learn to question assumptions, analyze arguments, and develop their own philosophical perspectives.
