The world is yours, as well as ours, but in the last analysis, it is yours. You young people, full of vigour and vitality, are in the bloom of life, … - Mao Zedong

There are a lot of things we can learn from the Soviet Union. Naturally, we should learn from its advanced and not its backward experience. The slogan we have advocated all along is to draw on the advanced Soviet experience. Who told you to pick up its backward experience? Some people are so undiscriminating that they say a Russian fart is fragrant. That too is subjectivism. The Russians themselves say it stinks. Therefore, we should be analytical. As we have indicated elsewhere, the assessment of Stalin should be 70 per cent for achievements and 30 per cent for mistakes. In the case of the Soviet Union what is good and useful makes up the essential and larger part and what is wrong only a small part. We too have things that are not good, and far from letting other countries pick them up, we should dump them. In a way, bad things are also some kind of experience and can serve a useful purpose. We have had people like Chen Tu-hsiu, Li Li-san, Wang Ming, Chang Kuo-tao, Kao Kang and Jao Shu-shih, who have served as our teachers. In addition, we have other teachers. Within the country the best among them has been Chiang Kai-shek. Those whom we couldn't convince were convinced right away when Chiang Kai-shek came along to give them a lesson. How did Chiang Kai-shek teach his lessons? He taught with machine-guns, cannon and planes. Imperialism is another teacher that has given our 600 million people an education. For over a century we were oppressed by several imperialist powers, and this has been an education. Therefore, bad things can serve an educational purpose and open our eyes.

According to materialist dialectics, changes in nature are due chiefly to the development of the internal contradictions in nature. Changes in society are due chiefly to the development of the internal contradictions in society, that is, the contradiction between the productive forces and the relations of production, the contradiction between classes and the contradiction between the old and the new; it is the development of these contradictions that pushes society forward and gives the impetus for the supersession of the old society by the new. Does materialist dialectics exclude external causes? Not at all. It holds that external causes are the condition of change and internal causes are the basis of change, and that external causes become operative through internal causes. In a suitable temperature an egg changes into a chicken, but no temperature can change a stone into a chicken, because each has a different basis. There is constant interaction between the peoples of different countries. In the era of capitalism, and especially in the era of imperialism and proletarian revolution, the interaction and mutual impact of different countries in the political, economic and cultural spheres are extremely great. The October Socialist Revolution ushered in a new epoch in world history as well as in Russian history. It exerted influence on internal changes in the other countries in the world and, similarly and in a particularly profound way, on internal changes in China. These changes, however, were effected through the inner laws of development of these countries, China included. In battle, one army is victorious and the other is defeated, both the victory and the defeat are determined by internal causes.
