Can schools encourage children to become independent moral decision-makers, maintaining controlled environments suitable to instructing large numbers of children? Two opposing responses are reviewed: one holds that the road to morality is through discipline and obedience, the other through children's experimentation and choice-making. Circumventing these polarities, I look to distinctions within rules that may help in balancing claims of restraint and freedom. Using a pharmacological analogy, one might, in principle, justify ‘pills’ for uncontrollable and/or morally trivial behaviors, but not for (...) intentional behaviors of moral significance where volition matters. However, since we cannot permit children to choose to harm, their agency must be curbed. As a compromise, I suggest that teachers hold extended moral discussions, and involve students in rule-making and sanction-giving. (shrink)
