The Null Device
The BBC News Magazine has an article about the shifting meaning of the adjective "bohemian", a word which used to started off describing vagabonds and those beyond the pale of respectable society, shifted via itinerant actors and musicians to refer to self-selected artistic outsiders who rejected bourgeois values and social norms, and now is increasingly used to refer to fashion-conscious types who engage in slightly more trendy modes of consumption (note the rise of "bobos", or "bourgeois bohemians", sometimes provocatively referred to as "White People").
In essence, bohemianism represented a personal, cultural and social reaction to the bourgeois life. And, once the latter was all but swept away by the maelstrom that was the 1960s, the former was doomed, too.Perhaps we need a word to refer to the "bohemians"-who-aren't-really-bohemians, in that, whilst engaging with culture outside of the feeding trough of the mainstream, they do live a comfortable bourgeois life, with respectable jobs, stable living arrangements and disposable income to spend on accoutrements such as limited-edition trainers, designer glasses, fancy bicycles and Apple products. How about the "avant-bourgeoisie"?
