This article describes the principles and the actualization of Korczak's moral education and explores how Korczak reconciled the differences between the ethical world he created in his institutions and the surrounding immoral society. The example set by Korczak's educational praxis serves as an inspiring model of school life across the boundaries of time and place and touches our need to believe in education's responsibility to strive and struggle for a better world, even when it seems an unattainable goal.
