Subsidiarity is an organizing principle stating that a matter ought to be handled by the smallest, lowest, or least centralized authority capable of addressing that matter effectively, and that a central authority should have a subsidiary function, performing only those tasks which cannot be performed effectively at a more immediate or local level.
Principle: Learning from grassroots community practices and early adopters, fostering growing awareness in each locality of the nature of local and global integration. This would draw from the people-context-interactions- assets-culture-resultant dynamic that defines and powers local relationships to the commons, and enable scaling vertically from there.
Emergence: Simple principles for a more realistic and purposeful science of economics and management for an animated world, drawing from "systems intervention", "action learning", "systems thinking" and "whole system assessment" practices, among others, to deal with the systemic complexity of the relationships and the shift required.
Amplificators: Promoting "connections" conversations to help build on interactions and facilitate integrated shifts in larger and smaller scale practices allowing stakeholders to discover new ways to solve their mutual problems. Adopt appreciative methods of enquiry and conflict resolution, being open to seeing things as they are, to experiment, learn and adjust. Encourage questioning, learning, discovery and innovation, and our capacity to bootstrap, to invent seeds of change, plant and nurture them, and evolve. Find ways to work together and actively engage in learning processes that enable co-creation and co-governance and conflict resolution on all scales.
Positive feedback: Expanding from the above on the "whole system" approach to learn from example, to mimic the conflict-free self-organization observable in natural economic systems, and other "exemplars" recognized good design; to observe patterns of behaviors emerging and to recognize change as it unfolds, so that theory is always checked against reality of what is observed and emerges, and new learning can be integrated and made applicable.
Application: This includes finding the boundaries and governance principles best suited to the needs of the commons at local levels (subsidiarity), acknowledging multiple logically or physically overlapping or intersecting commons, and devising more practical means of enforcement for laws, treaties, and agreements at all levels by making them confirmations of nested and/or fractal common needs.
