The Oxford English Dictionary's definition mentions someone "especially an artist, literary man, or actor, who leads a free, vagabond, or irregular life, not being particular as to the society he frequents, and despising conventionalities generally".
It is a contributing force in the foundation of the Romantic movement of the 19th century. As Andy Walker stated in his BBC news magazine article 'What is bohemian?' "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."
Real bohemians are individualistic. They are not driven by the ideals bestowed by society or interested in financial monetary gain to get ahead. The bohemian philosophy is about expressionism and freedom. Bohemians can be made up of a diverse background of mixed ethnicity and tend to bring rich experiences by offering artistic diversity. Society needs more bohemians as these individuals make a positive contribution to society by using their creative energy, style and vision to allow cultures to grow, flourish and thrive.
We love this inspiring TED Talk by Dr James Lough on why "we need more bohemians" and "how they they becoming an endangered species".
