According to Dominique Wolton, there is not much truth in this cosmopolitan pretension, and it is dangerous to be lulled into it. He argues that in order to co-exist peacefully and make progress in a world which is more and more open and therefore uncertain, one needs to be confident about one’s own identity to be the more prepared to face other sets of values. As he sees it, the more visible our differences, and the less these differences are recognized, the greater the tensions that arise. Wolton’s helpful book focuses all these issues into this most important question: how we can peacefully organize a culturally diverse world.
