Abstract
One of the pressing challenges we face today—in a post-Westphalian order and post-Bretton Woods world —is how to design the right kind of MAS that can take full advantage of the socio-economic and political progress made so far, while dealing successfully with the new global challenges that are undermining the best legacy of that very progress. This is the topic of the article. In it, I argue that in order to design the right kind of MAS, we need to design the right kind of norms that constitute them; in order to design the right kind of constitutive norms, we need to identify and adopt the right kind of principles of normative design; toleration is one of those principles; unfortunately, its role as a foundation for the design of norms has been undermined by the “paradox of toleration”; however, the paradox can be solved; so toleration can be re-instated as the right kind of foundational principle for the design of the right kind of norms that can constitute the right kind of MAS that can operate across cultures, societies and states, to help us to tackle the new global challenges facing us
