Masculinism in Science Fiction: Le Guin vs. Haldeman
Science fiction has always been a masculine genre, no matter that Mary Shelley invented it in her novel Frankenstein. Until fairly recent times, most science fiction writers were men, and they dealt with subjects like technology, power, space battles, featuring male heroes, explorers and adventurers. In film, science fiction has been a perfect subject for ultra-masculine actors like Arnold Schwarzenegger, although Lieutenant Ripley in the Alien trilogy proved that women could be masculine heroes as well and very effective at destroying hostile creatures that threaten humanity. Joe Haldeman's novel Forever Peace certainly fits within this conventional masculine narrative in science fiction, since the story is related by a male narrator named Sergeant Julian Class, an alienated soldier of the First World who opposes his own government and society. He is a class type of alienated and disillusioned male hero who nevertheless hopes that the world can achieve peace and prosperity through better use of technology. Even though it was written thirty years before, Ursula Le Guin's The Left Hand of Darkness is a radical departure from these types of themes and characters, since it takes place on an underdeveloped planet called Gethen far in the future.
Debating NASA's Budget: Worth, Waste, and the Future
As the increasingly impotent federal government lurches towards the edge of a self-imposed fiscal cliff, the public and politicians alike have largely accepted the inevitability of deep cuts to the nation's massively inflated budget. While there is still rancorous debate over exactly how the proverbial belt should be tightened, with conservatives demanding reductions in so-called entitlement programs and liberals countering with decreased military spending, a consensus seems to have emerged regarding the budgetary necessity of the National Aeronautics and Space Administration (NASA). Considered by many symbol of bureaucratic waste, with billions of dollars being devoted to implausible missions and esoteric experiments, NASA has been universally targeted as an expendable asset during economic turmoil.
