Peace studies draws on many different disciplines to understand the causes of conflict, as well as how to prevent war and human rights violations, and build peaceful societies. Justice is central to the discipline. To achieve justice, we must strive for a situation of just and harmonious communities.
Pope Paul VI, in a letter to Manhattan College on the occasion of the inaugural peace studies convocation in 1967
Peace is not something that is won and achieved for all time. It is a state that has to be nourished constantly with works of peace ...It is imperative to educate in the ways of peace and to be educated in those same ways.
