Tall order! Start local: be an examplar of how to live with minimal harm, with respect for others. (And when that fails, at least patience & tolerance.) Do more asking and listening than making yourself heard. Make room for voices that aren’t often heard. Grant those around you dignity and agency. When you encounter injustice, say so, and do what you can to correct it, because peace is unlikely without justice. When you make mistakes, apologize and make amends. There are many courses at BC in political science, philosophy, sociology, and theology that address issues of peace and justice.
