In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence--- as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch（关键时刻）, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instinct remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learned that violence never solves a problem but makes it even acute. The sheer horror, the bloodshed（流血）, the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.

The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persuaded by their own kind because they advocate such apparently outrageous things as law enforcement（执行）. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.
