It is the basic requirement of dialectical materialism to look at the problem from the perspective of connection. Looking at a problem from the perspective of connection means that when we examine a specific thing, we must analyze it in connection with everything related to it, so as to accurately grasp its nature, characteristics and the law of its emergence, movement, development and change. The reason why we should look at the problem from the perspective of connection is because there is a universal connection between things in the world itself. There is nothing absolutely isolated in the world. They are always connected in one way or another. The independence of things is relative, and the connection is absolute. The only difference is the way and degree of contact. There are some direct and indirect connections between them. Have a plenty of primary contact and have a plenty of secondary contact; Some are closely linked, while others are loosely linked; Some are vertical and some are horizontal. It is also the basic requirement of dialectical materialism to look at problems from a contradictory point of view. The world is universally connected, and universally connected things are interdependent and influential; At the same time, because of their different nature, they are contradictory and struggle with each other, thus promoting the development of things. Because of the different nature of things, it determines the different nature and way of contact between things, and also determines the different contradictory nature between one thing and other things, and the different characteristics and ways of contradictory struggle. Such as principal contradiction and secondary contradiction, principal and secondary aspects of contradiction, antagonistic contradiction and non-antagonistic contradiction; Direct struggle, indirect struggle, violent struggle, non-violent struggle, positive struggle, negative struggle, fierce struggle, moderate struggle and so on. Without the contradiction principle of things, it is impossible to examine how specific things should or will develop and move. According to Marx's principle of scientific socialism, it is not a moral choice to investigate whether China should take the capitalist road or the socialist road. We can only find the answer from the universal social contact and its contradictory movement in the world today. First of all, let's take a look at the main tasks faced after the liberation of China, that is, after the victory of the new-democratic revolution, and the surrounding world environment. What are the main tasks facing China? That is to develop productive forces as soon as possible and make yourself strong, otherwise it will be difficult to fundamentally get rid of the fate of being bullied and oppressed by imperialism. What is the surrounding environment like? Is that China has been surrounded by advanced capitalist countries and imperialism. Then look at your own situation, productivity is so backward, everything is in ruins after the war. To make China strong as soon as possible and get rid of this situation and fate, we must choose a basic system that can develop productive forces as soon as possible and make China strong. To establish such a system, we must have the following functions and effects: first, we must be able to mobilize all positive factors to the maximum extent and apply productivity to the extreme; Second, we must be able to develop productive forces at the fastest speed; Third, we should be able to maximize the role of productive forces for a long time and develop them at the fastest speed for a long time. To achieve this, this system must be for the benefit of the vast majority of people, and it must not be a system in which a few people oppress the majority. If the exploitation system in which a few people oppress the majority remains, firstly, it is impossible to arouse the enthusiasm of the overwhelming majority, and secondly, even if temporary development is achieved, with the emergence of polarization between the rich and the poor, social unrest and uneasiness will inevitably begin. In order to maintain order and class interests, the rulers in power will inevitably use state machines to suppress and even violently subdue. If the social contradictions are fierce, it may even eventually lead the rulers to seek assistance from foreign forces, and the country will be torn apart again, thus failing to continuously ensure the maximum development of productive forces; To do this, we must be able to complete the original accumulation needed to embark on the road of industrialization at the fastest speed. This is only the best choice to implement public ownership. Imagine how many industries were there in China before liberation. Even matches are called matches, let alone agriculture. Even in the rural areas I saw in the 1960s and 1970s, many farmers still lived in thatched huts, and the previous generation of farmers said to us from time to time, "You are really enjoying yourself being born in a new society. You have a house to live in, books to read, food to eat and clothes to wear. " This shows what the countryside was like in the old society. On this basis, if we still proceed from free capitalism, when can we get it? Capitalism in western countries took hundreds of years to complete its primitive accumulation. As we all know, "miser" is the process of primitive accumulation. Maybe you will be eaten again before this process is over! The choice of public ownership must be the people's democratic dictatorship, giving the broad masses of people the right to be masters of their own affairs and full and powerful supervision over the staff of general state organs; On the other hand, it will exercise dictatorship over those who destroy public property and this public system, otherwise, public property will inevitably be occupied by a few people. Public ownership and people's democratic dictatorship, that is, the proletariat and the broad masses of the people are masters of their own affairs and exercise dictatorship over a few hostile elements and saboteurs, is a brand-new system in China, which is the socialist system. Only by choosing this system can we meet the development laws and requirements of China society, because only in this way can China get rid of poverty and backwardness as soon as possible and finally overcome the encirclement and oppression of capitalist countries that have developed to the imperialist stage. This is also why it is difficult for other countries that have got rid of colonies to continue to engage in capitalism. This truth can also analyze why the social system of some countries or regions has advanced by leaps and bounds. Everything is related to its specific historical conditions and is the result of the whole social contradictory movement. Don't believe it? Makeup theorists can try. Mao Zedong said that it is actually the truth to think that China's society is underdeveloped and its productive forces are backward, and that the viewpoint of advocating the capitalist period is mechanical materialism. Mechanical materialists often don't know how to look at problems from the perspective of connection and contradiction, so they don't know that connection is a contradictory connection and contradiction is a contradiction of connection; I don't know how to find the answer from the contradictory movement between specific interrelated things; It is believed that the movement of the world is a kind of mechanical movement, and at the same time, in terms of the regularity of movement, only the universality of the movement law of things is paid attention to, while the particularity of the movement law of things and the complexity of the movement mode and characteristics are ignored, so that the concrete analysis of specific problems is not understood, and all social movements are viewed with this kind of movement. It seems that every country or region has to make a gradual transition from one society to another, without one.
