Four Upbuilding Discourses (1844) is the last of the Eighteen Upbuilding Discourses published during the years 1843–1844 by Søren Kierkegaard. He published three more discourses on "crucial situations in life" (Three Discourses on Imagined Occasions) in 1845, the situations being confession, marriage, and death. These three areas of life require a "decision made in time". Source: Wikipedia (en)
