This book aims to find out what "ought to be" the morality of world politics for the troubled colossus of humanity. Countries have different systems and cultures: This causes differences in their standard of living and a mix of "consumerism" and demographic "explosion" damaging the planetary ecosystem. I propose to differentiate morality from religion to provide a juridical base for a restricted "government of global affairs" whose decisions be taken in proportion to the economic capacity of countries. I backed up this proposal: First showing the very old evolutionary origin of morality in the hominid groups and the recent one of religion, when man reached high consciousness, and morality became included in the mythology of religion. Second, by elaborating a working hypotheses that morality would be, at its core, very stable, and religion changing and divisive among separated groups, and testing it throughout all of history, finding overwhelming evidence favoring our proposal.
