231 Negotiation often becomes necessary for shaping concrete paths to peace. Yet the processes of change that lead to lasting peace are crafted above all by peoples; each individual can act as an effective leaven by the way he or she lives each day. Great changes are not produced behind desks or in offices. This means that “everyone has a fundamental role to play in a single great creative project: to write a new page of history, a page full of hope, peace and reconciliation”. There is an “architecture” of peace, to which different institutions of society contribute, each according to its own area of expertise, but there is also an “art” of peace that involves us all. From the various peace processes that have taken place in different parts of the world, “we have learned that these ways of making peace, of placing reason above revenge, of the delicate harmony between politics and law, cannot ignore the involvement of ordinary people. Peace is not achieved by normative frameworks and institutional arrangements between well-meaning political or economic groups… It is always helpful to incorporate into our peace processes the experience of those sectors that have often been overlooked, so that communities themselves can influence the development of a collective memory”.
