I've come to understand the cumulative dialogue of my work as a kind of cartography of wisdom about our emerging world. This book is a map in words to important territory we all are on now together. It's a collection of pointers that treat the margins as seriously as the noisy center. For change has always happened in the margins, across human history, and it's happening there now. Seismic shifts in common life, as in geophysical reality, begin in spaces and cracks.
