The lessons of the nation's past tell us that liberty and justice cannot be secured for ourselves and kept from others without turning sour. Because we have cherished liberty for others, this country has sacrificed enormously (if not always wisely) in lives and material resources. We have not cherished justice as much. But justice and equality are no less a part of the nation's ideals, and we build on them by exercising them in our relationship with others. When we are rich and others are hungry or impoverished beyond description, justice calls for ending this imbalance.
