Jonathan Spence, our foremost historian of Chinese politics and culture, tells us in his new book how the West has understood China over seven centuries. Ranging from Marco Polo's own depiction of China and the mighty Khan, Kublai, in the 1270s to the China sightings of three 20th-century writers of acknowledged genius -- Kafka, Borges, and Calvino -- Spence explores Western thought on China through a remarkable array of expression. Peopling Spence's account are Iberian adventurers, the great Jesuit missionaries, Enlightenment synthesizers including Voltaire and Montesquieu, spinners of the dreamy cult of Chinoiserie, American observers such as Bret Harte, Mark Twain, Ezra Pound, and Eugene O'Neill, and diplomats from Britain's Lord Macartney to Henry Kissinger. Their visions are alternately coarse and subtle, generous and vicious, sober and exotic. Taken together they tell us as much about the self-image of the West as about China.
