When the authors of this fascinating study traveled around the world, they realized that modern societies had a lot to learn from indigenous cultures. In Enquêtes sur les savoirs indigènes, Crossman and Barou chose to approach the traditional cultures of three populations, Tibetans, Navajo, and Australian aboriginees, and take stock of their wisdom through their art, medicine and beliefs. Nechung, the Tibetan state Oracle; Sam Begay, the Navajo medicine-man who heals with Hozho, the Navajo word for beauty and health; and Emily Kame Kngwarreye, an Australian painter, all three guide Crossman and Barou in their journey. With their help, we discover how ancestral wisdom is indeed true knowledge.
