158 Here, there can be a misunderstanding. “‘People’ is not a logical category, nor is it a mystical category, if by that we mean that everything the people does is good, or that the people is an ‘angelic’ reality. Rather, it is a mythic category… When you have to explain what you mean by people, you use logical categories for the sake of explanation, and necessarily so. Yet in that way you cannot explain what it means to belong to a people. The word ‘people’ has a deeper meaning that cannot be set forth in purely logical terms. To be part of a people is to be part of a shared identity arising from social and cultural bonds. And that is not something automatic, but rather a slow, difficult process… of advancing towards a common project”.
