The failure to effectively confront major challenges facing humanity, most importantly, the global ecological crisis, it is argued, is due to the failure of those analysing the root causes of these challenges to engage with and invoke political philosophy to find a way out, and concomitantly, the failure of ethical and political philosophers to effectively engage with the deep assumptions, power structures and dynamics actually operative in the current world-order. It is claimed that this is due to a tacit acceptance (...) of a cultural dualism manifest in the opposition between the sciences and the humanities, with the humanities having been marginalized by the sciences. To overcome this dualism and marginalization of the humanities, and to defend communitarian ethical and political philosophy in a way that both challenges mainstream thinking and engages with the world as it is, with the potential to inspire and orient people for effective action, it is shown how communitarian ethical and political philosophy can be defended and developed through ecology incorporating the notion of ecopoiesis. It is shown how this can serve to create an effective counter-hegemonic culture, integrated as a dialogic grand narrative, uniting and orienting people to create a multi-polar world-order as an ecological civilization.

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.
