Question: What do Walter Lippmann and Michael Shaara have in common?
Context: "Soldier Boy" (also known as "X Minus One #71: 56-10-17 Soldier Boy") is a 1953 science fiction short story by American author Michael Shaara, about a soldier who, when sent on a routine patrol to a colonized world, saves the planet from an alien and its robot attack devices.  Despite an ingrained contempt for the military that arose as part of conditioning to avoid war, the human colonists gradually assist the soldier when strange occurrences suggest they are not alone on the planet and may be, like several other colony planets, under threat of extermination by outside forces.  It was originally published in the July 1953 issue of "Galaxy Science Fiction".  It is also the title of a 1982 collection of Shaara's short stories Gods and Generals is a novel which serves as a prequel to Michael Shaara's 1974 Pulitzer Prize-winning work about the Battle of Gettysburg, "The Killer Angels".  Written by Jeffrey Shaara after his father Michael's death in 1988, the novel relates events from 1858 through 1863 during the American Civil War, ending just as the two armies march toward Gettysburg.  Since 1988, Jeff Shaara has written "The Last Full Measure", which follows the events presented in "The Killer Angels". Michael Shaara (June 23, 1928 – May 5, 1988) was an American author of science fiction, sports fiction, and historical fiction.  He was born to Italian immigrant parents (the family name was originally spelled Sciarra, which in Italian is pronounced in a similar way) in Jersey City, New Jersey, graduated in 1951 from Rutgers University, where he joined Theta Chi, and served as a sergeant in the 82nd Airborne Division prior to the Korean War. The Walter Lippmann Colloquium, in French Colloque Walter Lippmann, was a conference of intellectuals organized in Paris in August 1938 by French philosopher Louis Rougier.  After interest in classical liberalism had declined in the 1920s and 1930s, the aim was to construct a new Liberalism as a rejection of collectivism, socialism and laissez-faire liberalism.  At the meeting the term neoliberalism was coined by Alexander Rüstow referring to the rejection of the (old) laissez-faire liberalism. Jeffrey M. "Jeff" Shaara (born February 21, 1952) is an American novelist, the son of Pulitzer Prize winner Michael Shaara. Drift and Mastery: An Attempt to Diagnose the Current Unrest is the second book by American journalist and political thinker Walter Lippmann.  Published in the Fall of 1914, "Drift and Mastery" argues that rational scientific governing can overcome forces of societal drift.  Lippmann argued that due to the profound social and economic change old ideas and institutions lacked relevance.  Specifically, "Drift and Mastery" warns against a reliance on broad theories and the framework of competition and self-interest.  Democracy and society at large, he argued, was unable to address problems because it was adrift, lacking intentionality and discipline.  Lippmann's prescription in "Drift and Mastery" was deliberate and scientific governing, what he termed mastery.  This forward-looking progressive vision sought a better society through rational, scientific order, while rejecting Marxist, Utopian and traditionalist thinking.  "Drift and Mastery" received enormously positive reviews, establishing Lippmann as an important public intellectual and figure within the progressive movement.  Although Lippmann later lost faith in the promise of science and rationality in government, "Drift and Mastery" was and is regarded as an important document of the progressive movement. Gettysburg is a 1993 American epic war film written and directed by Ronald F. Maxwell, adapted from the historical novel "The Killer Angels" (1974) by Michael Shaara, about the Battle of Gettysburg during the American Civil War.  The film stars Tom Berenger, Jeff Daniels, and Martin Sheen; its score was composed by Randy Edelman.  The film "Gods and Generals" is an adaptation of the 1996 novel of the same name by Jeffrey Shaara and was filmed as a prequel to Maxwell's "Gettysburg". The Phantom Public is a book published in 1925 by journalist Walter Lippmann in which he expresses his lack of faith in the democratic system by arguing that the public exists merely as an illusion, myth, and inevitably a phantom.  As Carl Bybee wrote, "For Lippmann the public was a theoretical fiction and government was primarily an administrative problem to be solved as efficiently as possible, so that people could get on with their own individualistic pursuits" (48). Gone for Soldiers is a 2000 historical novel by Jeffrey Shaara about the Mexican-American War.  It was written as a stand-alone novel, but could also be seen as a prequel to the Civil War trilogy written by Shaara and his father, Michael Shaara, introducing some of the key protagonists in the campaigns that first won them fame.  The action begins with the Battle of Vera Cruz and follows Winfield Scott and his army as they march toward Mexico City, including the Battle of Cerro Gordo and culminating in the Battle of Chapultepec and the fall of Mexico City. Walter Lippmann (September 23, 1889 – December 14, 1974) was an American writer, reporter, and political commentator famous for being among the first to introduce the concept of Cold War, coining the term "stereotype" in the modern psychological meaning, and critiquing media and democracy in his newspaper column and several books, most notably his 1922 book "Public Opinion".  Lippmann was also a notable author for the Council on Foreign Relations, until he had an affair with the editor Hamilton Fish Armstrong's wife, which led to a falling out between the two men.  Lippmann also played a notable role in Woodrow Wilson's post World War I board of inquiry, as its research director.  His views regarding the role of journalism in a democracy were contrasted with the contemporaneous writings of John Dewey in what has been retrospectively named the Lippmann-Dewey debate.  Lippmann won two Pulitzer Prizes, one for his syndicated newspaper column "Today and Tomorrow" and one for his 1961 interview of Nikita Khrushchev.
