It can be argued that civilized society is founded not on the principle of loving thy neighbor but on the "pretense" of loving thy neighbor, a less demanding practice we call "civility."
Today, as we witness the decline of civility, and the erosive impact of that decline on society, we come to a realization -- that pretense is difficult to sustain, that truly loving thy neighbor, as the gospels preach, might always have been the easier path.
