"Bohemias. Alternative subcultures. They were a crucial aspect of industrial civilization in the two previous centuries. They were where industrial civilization went to dream. A sort of unconscious R&D, exploring alternate societal strategies. Each one would have a dress code, characteristic forms of artistic expression, a substance or substances of choice, and a set of sexual values at odds with those of the culture at large. And they did, frequently, have locales with which they became associated. But they became extinct."
