In this novel - a story of irreconcilable loves and infidelities - Milan Kundera addresses himself to the nature of twentieth-century Being In a world in which lives are shaped by irrevocable choices and by fortuitous events, a world in which everything occurs but once, existence seems to lose its substance, its weight. We feel, says the novelist, the unbearable lightness of being - not only as the consequence of our private acts but also in the public sphere, and the two inevitably intertwine. n n Juxtaposing Prague, Geneva, Thailand and the United States, this masterly novel encompasses the extremes of comedy and tragedy, and embraces, it seems, all aspects of human existence. It offers a wide range of brilliant and amusing philosophical speculations and it descants on a variety of styles. In this classic novel Kundera draws together the Czechoslovakia of the Prague Spring and the Russian invasion, the philosophy of Nietzsche, and the love affairs of a number of heartbreakingly familiar characters. n
