Make up deficiency by the reputed dictionary of synonyms

The history of mankind is one of continuous development from the realm of necessity to the realm of freedom. This process is never-ending. In any society in which classes exist class struggle will never end. In classless society the struggle between the new and the old and between truth and falsehood will never end. In the fields of the struggle for production and scientific experiment, mankind makes constant progress and nature undergoes constant change, they never remain at the same level. Therefore, man has constantly to sum up experience and go on discovering, inventing, creating and advancing. Ideas of stagnation, pessimism, inertia and complacency are all wrong. They are wrong because they agree neither with the historical facts of social development over the past million years, nor with the historical facts of nature so far known to us (i.e., nature as revealed in the history of celestial bodies, the earth, life, and other natural phenomena).

Quoted in Premier Chou Enlai\'s Report on the Work of the Government to the First Session of the Third National People\'s Congress of the People\'s Republic of China (December 21-22, 1964).


毛主席曾说：“人类的历史，就是一个不断地从必然王国向自由王国发展的历史。这个历史永远不会完结。在有阶级存在的社会内，阶级斗争不会完结。在无阶级存在的社会内，新与旧、正确与错误之间的斗争永远不会完结。在生产斗争和科学试验范围内，人类总是不断发展的，自然界也总是不断发展的，永远不会停止在一个水平上。因此，人类总得不断地总结经验，有所发现，有所发明，有所创造，有所前进。停止的观点，悲观的观点，无所作为和骄傲自满的观点，都是错误的。其所以是错误，因为这些论点，不符合大约一百万年以来人类社会发展的历史事实，也不符合迄今为止我们所知道的自然界（例如天体史，地球史，生物史，其他各种自然科学史所反映的自然界）的历史事实。”（《毛主席语录》第174—175页）

Although Mao himself became a barrier of his words sometimes, this quote is thought provoking, my finding in the word analysis made me to recall this eloquent statement.
The book I\'ll make up some deficiency published almost three decade years ago with a team of specialists. As always, no one can exhaust the discovery of truth.
