The discovery in the 1990s of the Portuguese writer Fernando Pessoa (1888-1935) is reminiscent of the discovery of Kafka in the 1950s. Much of Pessoa's mystique comes from his unique practice of writing under different "heteronyms", each of which generated radically different texts. In THE BOOK OF DISQUIET, Pessoa came as close as he would to autobiography. Here is a 20th-century masterpiece in its best English translation and most affordable edition.
