A rousing defense of cosmopolitanism, told through the development of the public museum. It's a defense of travel for all of us unable to afford the rigors of international movement. The enlightenment, encyclopedic collections as a base upon which the rich cultures, ideas, movements of the world can be appreciated. It puts to shame those of us who visit art museums to see what we like: it's an education, possibly the most essential for maintaining comprehensive human relations. A shot's taken at the antithesis, the parochial, as advanced by thinkers like Burke in the eighteenth century through the never-ending growth of conservatism--all of which seems to prefer established power, nationalism, and religion to democracy, community, and conversation. 'Cosmopolitan' is my new favorite word (it used to be 'metropolitan', but let's aim higher shall we?).
