The old Bohemian definition was “a vagabond, a wayfarer”. Possibly that definition may, to a certain extent, be true of the present-day Bohemian, for he is a mental vagabond and mental wayfarer. The word comes from the French “Bon Homme” for surely the Bohemian is a good man.
In first place, the Bohemian is always a man with hobby. He may have more than one, but one must have, and that not a mare theoretic and speculative, but substantial, material, money-costing hobby.
Secondly, Bohemian is generous; free of his money when he has any, and sometimes when he has not.
Thirdly, the Bohemian has general inaptitude for business.
