Integration of the truths, workabilities and applicabilities of opposing orthodoxies is what is needed. Only a thorough integration will get us to what is a simultaneous conceptual and policy thirdness that is also a unifying oneness. And those policies must be ongoing and ethically ascendant as well. Grace as in Gifting is that missing monetary and economic concept, but for it to be truly effective and resolving the policies that result from that gifting must align with as many of the aspects of the concept of Grace as possible. Otherwise the temporal systems it is applied to will again descend into duality and unnecessary contentiousness.
This is neither merely natural philosophy nor supernatural religion, but an integration of both which is natural metaphysics/spirituality. And it is also of course Wisdom which being the best guide for both personal development and systemic policy….by definition can be neither irrelevant nor not of the highest ethical purpose and effect.
