Entity realism is a philosophical position within the debate about scientific realism. Whereas traditional scientific realism argues that our best scientific theories are true, or approximately true, or closer to the truth than their predecessors, entity realism does not commit itself to judgments concerning the truth of scientific theories. Instead, entity realism claims that the theoretical entities that feature in scientific theories, e.g. 'electrons', should be regarded as real if and only if they refer to phenomena that can be routinely used to create effects in domains that can be investigated independently. 'Manipulative success' thus becomes the criterion by which to judge the reality of (typically unobservable) scientific entities. As Ian Hacking, the main proponent of this formulation of entity realism, puts it (referring to an experiment he observed in a Stanford laboratory, where electrons and positrons were sprayed, one after the other, onto a superconducting metal sphere), "if you can spray them, then they are real."

Howard Zinn (August 24, 1922 – January 27, 2010) was an American historian, academic, author, playwright, and social activist. Before and during his tenure as a political science professor at Boston University from 1964-88 he wrote more than 20 books, which included his best-selling and influential A People's History of the United States. He wrote extensively about the civil rights and anti-war movements, as well as of the labor history of the United States. His memoir, You Can't Be Neutral on a Moving Train, was also the title of a 2004 documentary about Zinn's life and work.

Zinn was born to a Jewish immigrant family in Brooklyn. His father, Eddie Zinn, born in Austria-Hungary, emigrated to the U.S. with his brother Samuel before the outbreak of World War I. Howard's mother Jenny Zinn emigrated from the Eastern Siberian city of Irkutsk.

Both parents were factory workers with limited education when they met and married, and there were no books or magazines in the series of apartments where they raised their children. Zinn's parents introduced him to literature by sending 10 cents plus a coupon to the New York Post for each of the 20 volumes of Charles Dickens' collected works. He also studied creative writing at Thomas Jefferson High School in a special program established by poet Elias Lieberman.

Grant Morrison (born 31 January 1960) is a Scottish comic book writer, playwright and occultist. He is known for his nonlinear narratives and counter-cultural leanings, as well as his successful runs on titles like Animal Man, Doom Patrol, JLA, The Invisibles, New X-Men, Fantastic Four, Action Comics, All-Star Superman, and Batman.

Grant Morrison was born in Glasgow, Scotland in 1960. His first published works were Gideon Stargrave strips for Near Myths in 1978 (when he was about 17), one of the first British alternative comics. His work appeared in four of the five issues of Near Myths and he was suitably encouraged to find more comic work. This included a weekly comic strip Captain Clyde, an unemployed superhero based in Glasgow, for The Govan Press, a local newspaper, plus various issues of DC Thomson's Starblazer, a science fiction version of that company's Commando title.

Morrison spent much of the early 1980s touring and recording with his band The Mixers, writing the occasional Starblazer for D. C. Thompson and contributing to various UK indie titles. In 1982 he submitted a proposal involving the Justice League of America and Jack Kirby's New Gods entitled Second Coming to DC Comics, but it was not commissioned. After writing The Liberators for Dez Skinn's Warrior in 1985, he started work for Marvel UK the following year. There he wrote a number of comic strips for Doctor Who Magazine, his final one a collaboration with a then-teenage Bryan Hitch, as well as a run on the Zoids strip in Spider-Man and Zoids. 1986 also saw publication of Morrison's first of several two- or three-page Future Shocks for 2000AD.
