Especially during the Tom Baker years.
The term Bohemians has two distinct meanings, having little to do with each other - one refers to the people of Bohemia, in the Czech Republic, the other can describe any person who lives an unconventional artistic life.
The Doctor traveled the universe. Rarely alone, always pulling along a rag tag group of companions. Some female, some male, some robotic. He had an outlook on life I think summed up best with this quote from "The Time Monster", "Brigadier, a straight line may be the shortest distance between two points, but it is by no means the most interesting." Wherever he went, there he was. Its was all cool. Usually for story reasons there was some evil that needed to be stopped and some problem to be solved. But the Doctor was always excited and always curious about where (and when) he was. Even when others were trying to kill him, he managed to befriend or sway someone (yeah I know for plot mechanics) to chill. The Doctor was well traveled, worldly, incredibly intelligent, agnostic, analytical and tolerant. He was an island of calm in a sea of fiery passion of his companions and his surroundings. He was an ideal. Something we, especially in these times, could learn from and there are worse to emulate.
