Jiddu Krishnamurti (May 11, 1895 – February 17, 1986)
Indian born speaker and writer on philosophical and spiritual subjects
Why is there, one must ask, this division—the Russian, the American, the British, the French, the German, and so on—why is there this division between man and man, between race and race, culture against culture, one series of ideologies against another? Why? Where is there this separation? Man has divided the earth as yours and mine—why? Is it that we try to find security, self-protection, in a particular group, or in a particular belief, faith? For religions also have divided man, put man against man—the Hindus, the Muslims, the Christians, the Jews and so on. Nationalism, with its unfortunate patriotism, is really a glorified form, an ennobled form, of tribalism. In a small tribe or in a very large tribe there is a sense of being together, having the same language, the same superstitions, the same kind of political, religious system. And one feels safe, protected, happy, comforted. And for that safety, comfort, we are willing to kill others who have the same kind of desire to be safe, to feel protected, to belong to something. This terrible desire to identify oneself with a group, with a flag, with a religious ritual and so on gives us the feeling that we have roots, that we are not homeless wanderers.

Always Question Authority 
Couldn’t agree more. Political maps are artificial maps, drawn in order that political control can be exercised over distinct groups of people. This is not necessarily or iinnately a bad thing. E.g., we need controls such a traffic laws in order to accommodate and get along with each other on roadways. The problem arises, as Krishnamurti says or implies, when we wish to also see these artificial boundaries as separating people in terms of good/evil, right/wrong. We too easily listen to the demagogues who exploit boundaries by appealing to our fears and desires for security.
