The author understands solidarity primarily as a legal concept of co-operative projects of forming an ever further expanded democratic legal community (Rechtsgenossenschaft). Solidarity is complementary to justice, and principle of democracy that is self-legislated includes both sides. Self-legislation, solidarity and justice are equally universal concepts. The first section of the chapter is a brief diagnosis of modern society under conditions of global crisis. Democratic solidarity must stand up to two crucial experimental checks, one is normative and the other factual. The second section of the chapter draws some political conclusions related to the most fundamental problems of the present world society. The final section tries to specify four changes political agencies need to adopt to save democratic solidarities under stress from globalisation.
