Completely agreed about "commonality of action." A goal behind truth units is to facilitate commonality of action. I've seen and read about so many people who are trying to achieve commonality of action, but have so much trouble "stipulating the facts" to create the platform, the foundation, the common ground, for creating the commonality you're talking about. In other words, truth units is meant as a tool to get to common ground by what might be the fastest, most direct route possible -- so they don't exhaust their spirit and energy arguing about the facts.
