“Every few hundred years throughout Western history, a sharp transformation has occurred. In a matter of decades, society all together rearranges itself - its worldview, its basic values, its social and political structure, its arts, and its key institutions. Fifty years later a new world exists. And the people born into that world cannot even imagine the world in which their own grandparents were born. Our age is in such a period of transformation. If history is a guide the transformation will be complete in 2010 to 2020.”
