Unfortunately, far more is needed. To be effective, a new set of institutions would have to be imbued with heavy-handed, transnational enforcement powers. There would have to be consideration of some way of embracing head-in-the-cloud answers to social problems that are usually dismissed by policymakers as academic naivete. In principle, species-wide alteration in basic human behaviors would be a sine qua non, but that kind of pronouncement also profoundly strains credibility in the chaos of the political sphere. Some of the things that would need to be contemplated: How do we overcome our hard-wired tendency to “discount” the future: valuing what we have today more than what we might receive tomorrow? Would any institution be capable of instilling a permanent crisis mentality lasting decades, if not centuries? How do we create new institutions with enforcement powers way beyond the current mandate of the U.N.? Could we ensure against a malevolent dictator who might abuse the power of such organizations?
