Unless we can find a way to live with diversity without screaming at each other or shooting each other, it's all over. Rudeness is rampant in our culture and it may affect our children more than acknowledged. But, verbal violence may lead to physical violence, and nastiness seems an odd aspiration. There is a political, ideological aspect to some of this rudeness. Another angle is described by Ted Seigel, professor of humanities at Cooper Union in New York.
Cultural rudeness is unacknowledged shadow.
We are all born whole, but somehow the culture demands that we live out only part of our nature and refuse other parts of our inheritance. The religious process consists of restoring the wholeness of the personality. The word religion means to re-relate, to put back together again, to heal the wounds of separation. One must break from the Garden of Eden, but one must also restore the heavenly Jerusalem. Charm, as I am using the term, is a spiritual practice.
