about two and a half centuries ago, the American naval commander Matthew Perry led a flotilla into Tokyo harbor. The Japanese, till then isolated,found themselves faced with a technology considerably beyond their own and decided it was unwise to risk resistance. An entire warlike nation of millions was helpless in the face of a few ships from across the sea.Did that prove that Americans were more intelligent than the Japanese were, or merely that Western culture had taken a different turning? Clearly the latter, for within half a century, the Japanese successfully imitated Western technology and within another half a century were a major industrial power despite the fact that they were disastrously beaten in one of the wars of the time.
