When it first emerged, “nostalgia” was described as a medical condition. The term was coined in 1688 by the Swiss physician Johannes Hofer, who tended to soldiers suffering from a mysterious ailment: a virulent homesickness, whose symptoms included high fever, stomach ache, and fainting spells. The condition later spread to proletarianised peasants who, forced into factory work, pined for their ancestral lifestyles. In 2003, Australian philosopher Glenn Albrecht, identified another form of displacement-related psychic distress, and named it “solastalgia.” Much like nostalgia, solastalgia hinges on a sense of alienation from one’s own environment. But whereas nostalgia relates to the uprooting of an individual, sufferers of solastalgia typically stay put – it’s their environment that gradually disappears.
