"In ancient America, Indians were a highly advanced, deeply sustainable society. They would not kill more buffalos than they needed to feed their tribes. They understood their impact on the world around them. But every society, just like every system, however virtuous it is, will not last, without an effective feedback mechanism. And that is what clowns do. Clowns provide feedback in their own way. The Indian clowns were called Heyokas and were perceived as sacred."
