Virtues are values underlying human practices. We are at the dawn of a new era, an era of global ethics requiring some core virtues. These core virtues are hospitality, co-living, respect, tolerance, and communality. Book 1 treats the virtue of hospitality that is a right and a duty of all, and which is still to be discovered and practiced unconditionally. Book 2 deals with the virtues of co-living, respect, and tolerance, which are important virtues if the peoples of the earth are to live together in peace in our common home, the planet Earth. Finally, Book 3 deals with the virtue of communality; this is a very important virtue because a large part of humanity experiences hunger and thirst, which is something scandalous in this day and age, and which demonstrates a lack of humanity, because we possess the technical means and political framework to resolve this situation. If these core virtues become a reality, they will transform human practices into something beneficial both to human beings and to the planet Earth, our common home.
