The Closing of the American Mind is a 1987 book by the philosopher Allan Bloom, in which the author argued that "higher education has failed democracy and impoverished the souls of today's students."
 He focused especially upon the "openness" of relativism as leading paradoxically to the great "closing" referenced in the book's title.
 In Bloom's view, "openness" and absolute understanding undermine critical thinking and eliminate the "point of view" that defines cultures.
 Bloom's book became an unexpected best seller, eventually selling close to half a million copies in hardback, but drew divided reactions from reviewers.
Rose in Bloom, by Louisa May Alcott, depicts the story of a nineteenth-century girl, Rose Campbell, finding her way in society.

 Its parents were a double-flowered "R.  multiflora" and a hybrid tea rose, either 'Souvenir d'un Ami' or a seedling of 'Mme de Tartas'.
 It is not clear if the rose was named after the sister (1853-1927) or daughter (b. 1879) of Ulrich Brunner fils.
