In my view, what an open city means is that peo­ple are exposed to one anoth­er. That’s my idea of the open city, that it’s a place where phys­i­cal pres­ence with the oth­er, and com­fort with the phys­i­cal pres­ence of the oth­er, does the work of allow­ing peo­ple to live togeth­er even if they are not engaged in the process of negat­ing their differences.
