Racial PrejudiceIn some countries where racial prejucide is acute, violence has been taken for granted as a means of solving differences; and this is not even questioned. There are countries 1 the white man imposes his rude by brute (粗暴) force; there are countries where the black man protests by 2 fire to cities and by looting and pillaging (抢夺). Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in 3 of violence as if it were a legitimate (合法的) solution, 4 any other. What is really frightening, what really 5 you with despair, is the realization that when it comes to the crunch (关键时刻), we have made no actual 6 at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded 7 of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that 8 never solves a problem but makes it more acute. The sheer horror, the bloodshed and the suffering 9 nothing. No solution ever comes to 10 the morning after when we dismally (阴郁地) contemplate the smoking ruins and wonder what hit us.The truly reasonable men who 11 where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted 12 their own kind because they advocate such apparently outrageous things as low enforcement. If half the energy that goes into 13 acts were put to good use, if our efforts were directed at 14 up the slums and ghettos (贫民窟), at improving living-standards and providing education and employment for all, we would not have gone a long way to 15 at a solution.
