The state system, a joint dictatorship of all the revolutionary classes and the system of government, democratic centralism--these constitute the pol… - Mao Zedong

对于人民内部，则实行民主制度，人民有言论集会结社等项的自由权。选举权，只给人民，不给反动派。这两方面，对人民内部的民主方面和对反动派的专政方面，互相结合起来，就是人民民主专政。

按照唯物辩证法的观点，自然界的变化，主要地是由于自然界内部矛盾的发展。社会的变化，主要地是由于社会内部矛盾的发展，即生产力和生产关系的矛盾，阶级之间的矛盾，新旧之间的矛盾，由于这些矛盾的发展，推动了社会的前进，推动了新旧社会的代谢。唯物辩证法是否排除外部的原因呢？并不排除。唯物辩证法认为外因是变化的条件，内因是变化的根据，外因通过内因而起作用。鸡蛋因得适当的温度而变化为鸡子，但温度不能使石头变为鸡子，因为二者的根据是不同的。各国人民之间的互相影响是时常存在的。在资本主义时代，特别是在帝国主义和无产阶级革命的时代，各国在政治上、经济上和文化上的互相影响和互相激动，是极其巨大的。十月社会主义革命不只是开创了俄国历史的新纪元，而且开创了世界历史的新纪元，影响到世界各国内部的变化，同样地而且还特别深刻地影响到中国内部的变化，但是这种变化是通过了各国内部和中国内部自己的规律性而起的。两军相争，一胜一败，所以胜败，皆决于内因。

A dangerous tendency has shown itself of late among many of our personnel -- an unwillingness to share weal and woe with the masses, a concern for personal fame and gain. This is very bad. One way of overcoming it is to streamline our organizations in the course of our campaign to increase production and practice economy, and to transfer cadres to lower levels so that a considerable number will return to productive work. We must see to it that all our cadres and all our people constantly bear in mind that ours is a large socialist country but an economically backward and poor one, and that this is a very big contradiction. To make China prosperous and strong needs several decades of hard struggle, which means, among other things, pursuing the policy of building up our country through diligence and thrift, that is, practicing strict economy and fighting waste.
