A lucid, humane guide to classroom practice that treats teaching as both craft and vocation, emphasizing careful preparation, clear exposition, and genuine enthusiasm to awaken curiosity and independent thought in students. It mixes practical advice on syllabus design, lecturing, discussion, testing and grading with attention to tone, language, and the teacher’s example — advocating respect for students’ individuality, rigorous standards tempered by encouragement, and the use of surprise, humor and vivid illustration to make ideas memorable. Grounded in classical learning yet applicable across subjects, it insists that the goal of education is not mere information transfer but formation of judgment, taste, and moral seriousness through patient guidance and inspired leadership.
