A utopia ( ) typically describes an imaginary community or society that possesses highly desirable or nearly perfect qualities for its members. It was coined by Sir Thomas More for his 1516 book Utopia, describing a fictional island society in the New World. However, it may also denote an intentional community. In common parlance, the word or its adjectival form may be used synonymously with "impossible", "far-fetched" or "deluded". Hypothetical utopias focus on—amongst other things—equality, in such categories as economics, government and justice, with the method and structure of proposed implementation varying based on ideology. Lyman Tower Sargent argues that the nature of a utopia is inherently contradictory because societies are not homogeneous and have desires which conflict and therefore cannot simultaneously be satisfied. To quote: The opposite of a utopia is a dystopia. Utopian and dystopian fiction has become a popular literary category. Despite being common parlance for something imaginary, utopianism inspired and was inspired by some reality-based fields and concepts such as architecture, file sharing, social networks, universal basic income, communes, open borders and even pirate bases. Etymology and history The word utopia was coined in 1516 from Ancient Greek by the Englishman Sir Thomas More for his Latin text Utopia. It literally translates as “no place”, coming from the (“not”) and τόπος (“place”), and meant any non-existent society, when ‘described in considerable detail’. However, in standard usage, the word's meaning has shifted and now usually describes a non-existent society that is intended to be viewed as considerably better than contemporary society. In his original work, More carefully pointed out the similarity of the word to eutopia, meaning “good place”, from (“good” or “well”) and τόπος (“place”), which ostensibly would be the more appropriate term for the concept in modern English. The pronunciations of eutopia and utopia in English are identical, which may have given rise to the change in meaning. Dystopia, a term meaning "bad place" coined in 1868, draws on this latter meaning. The opposite of a utopia, dystopia is a concept which surpassed utopia in popularity in the fictional literature from the 1950s onwards, chiefly because of the impact of George Orwell's Nineteen Eighty-Four. In 1876, writer Charles Renouvier published a novel called Uchronia (French Uchronie). The neologism, using chronos instead of topos, has since been used to refer to non-existent idealized times in fiction, such as Philip Roth's The Plot Against America (2004), and
