When definitions of “us” and “them” begin to contract, there seems to be no limit to how narrow these definitions can become. As they shrink and narrow, they are increasingly inflamed, more dangerous and inhumane. They present themselves as movements toward truer and purer community, but, as I have said, they are the destruction of community. They insist that the imagination must stay within the boundaries they establish for it, that sympathy and identification are only allowable within certain limits. I am convinced that the broadest possible exercise of imagination is the thing most conducive to human health, individual and global.
