We divide ourselves race by race, nation by nation, religion by religion, sect by sect, through even further derivatives until the fact of our shared humanity becomes irrelevant. It becomes ‘us’ vs ‘them’, as if we were somehow constituted a different way. We fail to see that our belonging to a particular group is superfical in a way that our being human is not. Yet we identify with these groups, feeling affinity with those we share them with, and so long as this continues there will be no unity. Until we can see all of humanity as our group, as like us, there will be no peace because we ruled out that possibility the moment we began to see in colour, nationality and religion, to justify our difference and raise a mental barrier between us and the rest of the world.
The fragmentation of humanity arises because of the difference between the ideas each group holds and the extent of this chasm even leads to war when it is pronounced enough. For peace to be possible we have to give up the ideas we divide ourselves by and come to regard other people as equal to us by virtue of being human. If something so simple and in line with reason seems beyond us, it will be the world itself that we burn down in flames.
