Time spent in a bookshop can be most enjoyable, whether you are a book-lover or only there to buy a book as a present. You may even have entered the shop just to find a shelter from a sudden shower. Whatever the reason, you can soon totally unaware of your surroundings. You soon become interested in some books or others, and usually it is only much later that you realize you have spent too much time there and have to rush off to keep some forgotten appointment.

This chance to escape the realities of everyday life is the main attraction of a bookshop. A music shop is very much like a bookshop. You can walk around such a place to your heart's content. If it is a good shop, no assistant will come up to you with the greeting "Can I help you?" You needn't buy anything you don't want. In a bookshop an assistant should remain in the background until you have finished reading. Then, and only then, are his services necessary.

Once a medical student had to read a textbook which was far too expensive for him to buy. He couldn't borrow it from the library and the only copy he could find was in a certain bookshop. Every afternoon, therefore, he would go along to the shop and read a little of the book at a time. One day, however, he was disappointed to find the book missing from his usual place. He was about to leave, when he noticed the owner of the shop beckoning to him. Expecting to be told off, he went towards him. To his surprise, the owner pointed to the book which was tucked away in a corner. "I put it there in case anyone tries to buy it !"He said, and left the delighted student continuing his reading.

材料一：（19世纪中期）两个学说都发现了变化的原因在于斗争……生存竞争和阶级斗争。”

——沃纳姆著《新编剑桥世界近代史》

材料二：马克思在总结巴黎公社的经验时指出，工人阶级不能简单地掌握现成的国家机器，并运用它来达到自己的目的。……巴黎公社在实行无产阶级专政方面“过于老实”。当凡尔赛大肆屠杀革命人士的时候，公社寓于迂腐的仁慈而未对市内的反革命分子采取坚决措施。

——列宁《国家与革命》

材料三：当代学者罗燕明系统论述了《 * * 党宣言》与中国的三次结合。他指出第一次结合发生在建党前后，……第二次结合发生在建党以后的民主主义革命时期，……实现了马克思主义与中国革命实践相结合的第一次飞跃。第三次结合发生在社会主义建设时期，表现为生产力观点与社会主义现代化建设实际的结合，……实现了马克思主义在中国的第二次飞跃。

——李军林《〈 * * 党宣言〉在中国：十年研究述评》

卡尔·马克思认为，各工业化国家将先于其各自的殖民地爆发革命。他指出，西方资本家正不断将其剩余资金投向殖民地，而在那里可以获得更高的利润。与他那个时代的所有社会主义者一样，马克思认为这些投资将持续下去，并且这些殖民地将成为像其西欧母国那样的资本主义工业化国家……

马克思也曾预期，随着各殖民地走向工业化和繁荣昌盛，原先西方的制造业中心将会因此衰落，并造成工人失业。这反过来最终会迫使受苦的西方工人阶级起来反抗并建立社会主义社会。因此，马克思得出结论：革命将首先在西方爆发……

今天，一个多世纪过去了，我们看到实际发生的情况与马克思所担心的完全相反。革命的爆发不是在西方，而是在原先西方的殖民地，即现在的第三世界。这样，历史把马克思的结论整个颠倒了过来。
