While thinking about where hippies come from, I revisited Bohemianism, which seems like an odd name for a similar phenomenon:
Literary “Bohemians” were associated in the French imagination with roving Romani people (called Bohémiens because they were believed to have arrived from Bohemia), outsiders apart from conventional society and untroubled by its disapproval. The term carries a connotation of arcane enlightenment (the opposite of Philistines), and carries a less frequently intended, pejorative connotation of carelessness about personal hygiene and marital fidelity.
The title character in Carmen (1876), a French opera set in the Spanish city of Seville, is referred to as a “bohémienne” in Meilhac and Halévy’s libretto. Her signature aria declares love itself to be a “gypsy child” (enfant de Bohême), going where it pleases and obeying no laws.
The Beatniks of the previous generation were much more interesting than the Hippies. Many of the Beatniks actually produced serious art and literature. The Hippies were unproductive of anything.
