The Book of Disquiet is a journal by Portuguese author Fernando Pessoa. Published by his friends in 1961, it contains Pessoa’s reflections beginning in 1912 at the age of twenty-four as he anticipated World War I. Pessoa wrote the book mainly for himself under the pseudonym Bernardo Soares, and it was not published until nearly half a century after he died in 1935. Though the format of the book is difficult to pin down, it reads like a diary or journal, dealing with the internal life of the seemingly banal “Soares” as he works as a simple assistant to a bookkeeper in Lisbon. The book became known as a great work in the genre of world literature for its simplistic yet poignant characterization of the ordinary life of a lower-class Portuguese person.
