The idea is to show, time and again, how justness as a quality of character depends on wonder as its core, extent, and ground, with justice being understood as a process of working out relationships into freeness for all involved.  The planetary part of that is to understand that justice depends on power from the planet - the freedom of being that makes relating possible at all for the living.  In this way, the book argues for an understanding of justness that focuses on generation.  Wonder is linked to it.
