This document discusses peace education and defines peace in a holistic way. It explains that early definitions of peace focused only on the absence of direct violence like war, but modern conceptions recognize that structural violence in the form of poverty, discrimination and environmental destruction also undermine peace. The document presents a model of positive peace as the absence of both direct and structural violence, as well as the presence of justice and human well-being. It categorizes different types of violence across personal, community, national and global levels as direct, structural, socio-cultural and ecological to provide a framework for understanding peace in comprehensive terms.
