I. Properly speaking, global thinking is not possible. Those who have "thought globally" (and among them the most successful have been imperial governments and multinational corporations) have done so by means of simplifications too extreme and oppressive to merit the name of thought. Global thinkers have been, and will be, dangerous people. National thinkers tend to be dangerous also; we now have national thinkers in the northeastern United States who look upon Kentucky as a garbage dump.
II. Global thinking can only be statistical. Its shallowness is exposed by the least intention to do something. Unless one is willing to be destructive on a very large scale, one cannot do something except locally, in a small place. Global thinking can only do to the globe what a space satellite does to it: reduce it, make a bauble of it. Look at one of those photographs of half the earth taken from outer space, and see if you recognize your neighborhood. If you want to see where you are, you will have to get out of your space vehicle, out of your car, off your horse, and walk over the ground. On foot you will find that the earth is still satisfyingly large, and full of beguiling nooks and crannies.
