‘We live in a world full of exemplars, but far from an exemplary world, a contradiction that fuels these subtle and richly satisfying analyses of how aspirational models of people and forms might circulate. This nuanced bouquet of chapters brings together interdisciplinary approaches that reveal the types of social coordination that must exist for exemplars to emerge, circulate, and in turn structure future possibilities that people thus learn to find worthwhile. This collection is a vital starting point for all who want to understand a world built to enable exemplars to spark social change.’ Ilana Gershon, Rice University
