In Our Time is the title of Ernest Hemingway and s first collection of short stories, published in 1925 by Boni and Liveright, New York, and of a collection of vignettes published in 1924 in France titled in our time. Its title is derived from the English Book of Common Prayer, "Give peace in our time, O Lord". The stories and s themes – of alienation, loss, grief, separation – continue the work Hemingway began with the vignettes, which include descriptions of acts of war, bullfighting and current events. The collection is known for its spare language and oblique depiction of emotion, through a style known as Hemingway and s "theory of omission" (iceberg theory). According to his biographer Michael Reynolds, among Hemingway and s canon, "none is more confusing ... for its several parts – biographical, literary, editorial, and bibliographical – contain so many contradictions that any analysis will be flawed."
