The Montessori Method, Chapter V, “Discipline,” printed page 86, Anne E. George translation, Project Gutenberg #39863. “Discipline must come through liberty” introduces Montessori’s account of active discipline and self-mastery in contrast with enforced immobility. It remains early-twentieth-century educational theory rather than a context-free rule for every classroom or child.
