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……在生产斗争和科学实验范围内,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。停止的论点,悲观的论点,无所作为和骄傲自满的论点,都是错误的。 Human history is a history of continuous development from a necessary kingdom to a free kingdom. This history will never come to an end. In the context of the struggle for production and scientific experiments, mankind always develops continuously. Nature has always evolved and will never stop at a level. Therefore, mankind always has to sum up his experience, find something, invent something, create something, and make progress. Arguments of cessation, pessimism, inaction and pride and complacency are all wrong.
