Sir Thomas More’s Utopia (1516) became a model for most utopian writers of the modern world. Although utopia literally means “no place,” More’s version is clearly a small island: “The Island of Utopia contains in breadth two hundred miles, saving that it comes in toward both the ends, which, forming a circuit of five hundred miles, fashion the whole island like to the new moon.” (More,1516, p.265) Utopian literature, following the example of More, often uses islands to satirize and critique the habits of mainland societies and to describe a constructive island way of life that avoids mainland evils and demonstrates positive alternatives. Bounded island settings make it possible to imagine ideal human communities free of poverty, greed, illness, warfare, and the other forms of suffering that characterize life on the mainland.
But islands have a darker side as well. The water boundary that limits the influence of mainlands upon islands can of course also be used to make islands places of confinement. That is why islands have always been popular places for prisons and for the exile of unwanted people. Alcatraz and Rikers Islands are well known American prison islands, but there are hundreds of other islands around the world that are places of incarceration for criminals, the insane, and the diseased. Guantanamo Bay is an island prison much in the news. When some of its prisoners were recently relocated, they were moved to the Pacific island of Palau. From medieval times, leprosy has confined thousands to island settings for isolation, including the famous leper colony on Molokai in the Hawaiian Islands. The imagination has often chosen islands as places to put people out of sight, out of mind (Tuan, 1979). Islands are also favorite places for nuclear and ballistic missile testing and for dumping toxic wastes. Even Vashon Island was judged to be an ideal place for Nike ballistic missiles during the Cold War.
