“Because the vocations of shepherds and teachers are appropriate for an established community, they are best characterized as being integrative and operative. They are natural integrators who help people with the assimilation of people and the information throughout the community. They are also operative because they are more inclined to drive the routine aspects of running and maintaining the community or organization than charting a new course. They optimize efficiency and resourcefulness rather than generate new forms.” – Alan Hirsch, The Permanent Revolution
