【正文】 ires than my old hike and seven gears. But it is greena brighter green bike. Still, I was a bit worried。 I was a lot older. I brought the bike home and put on my helmet I39。d never worn a helmet before. Then I got on the bike. After a difficult start, I felt exactly as I was on that longago day on Springfield Avenue: free. Soon I was riding along, watching the waves break. It seemed that everyone I passed smiled.

War is an ancient institution which has existed for at least six thousand years. It was always bad and usually foolish, but in the past111] the human race managed to live with it. Modem creativity has changed this. Either man will abolish war, or war will abolish man. For the present, it is nuclear weapons that cause the most serious danger, but bacteriological (使用細(xì)菌的 )or chemical weapons, may soon offer an even1111] greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international problems in a new way, not by contests of force, in which the victory goes to the side which is the most skillful in killing people, but by arbitration (仲裁 ) according to agreed principles of law. It is not easy to change very old mental habits, but this what must be attempted. There are those who say that the adoption of this or that thought would prevent war. I believe this to he a big error. All thoughts are based on statements which are, at best, doubtful, and at worst, totally false. Their followers believe in them that they are willing to go to war in support them. The movement of world opinion during the past few years has changed very largely such as we can wele. It is believed that nuclear war must be avoided. Of course very difficult problems remain in the world, hut the attitude towards them is a better one than it was several years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that people should reach agreements even if both sides do not find these agreements wholly satisfactory.
