Fratelli Tutti, §27
We have certain ancestral fears that technological development has not succeeded in eliminating; indeed, those fears have been able to hide and spread behind new technologies. Today, too, outside the ancient town walls lies the abyss, the territory of the unknown, the wilderness. Whatever comes from there cannot be trusted, for it is unknown, unfamiliar, not part of the village. It is the territory of the “barbarian”, from whom we must defend ourselves at all costs. As a result, new walls are erected for self-preservation, the outside world ceases to exist and leaves only “my” world, to the point that others, no longer considered human beings possessed of an inalienable dignity, become only “them”. Once more, we encounter “the temptation to build a culture of walls, to raise walls, walls in the heart, walls on the land, in order to prevent this encounter with other cultures, with other people. And those who raise walls will end up as slaves within the very walls they have built. They are left without horizons, for they lack this interchange with others”.
Pope Francis
