As opposed to the metaphysical world outlook, the world outlook of materialist dialectics holds that in order to understand the development of a thin… - Mao Zedong

As we have said, one must not treat all the contradictions in a process as being equal but must distinguish between the principal and the secondary contradictions, and pay special attention to grasping the principal one. But, in any given contradiction, whether principal or secondary, should the two contradictory aspects be treated as equal? Again, no. In any contradiction the development of the contradictory aspects is uneven. Sometimes they seem to be in equilibrium, which is however only temporary and relative, while unevenness is basic. Of the two contradictory aspects, one must be principal and the other secondary. The principal aspect is the one playing the leading role in the contradiction. The nature of a thing is determined mainly by the principal aspect of a contradiction, the aspect which has gained the dominant position.

Being a bourgeoisie in a colonial and semi-colonial country and oppressed by imperialism, the Chinese national bourgeoisie retains a certain revolutionary quality at certain periods and to a certain degree--even in the era of imperialism--in its opposition to the foreign imperialists and the domestic governments of bureaucrats and warlords (instances of opposition to the latter can be found in the periods of the Revolution of 1911 and the Northern Expedition), and it may ally itself with the proletariat and the petty bourgeoisie against such enemies as it is ready to oppose. In this respect the Chinese bourgeoisie differs from the bourgeoisie of old tsarist Russia. Since tsarist Russia was a military-feudal imperialism which carried on aggression against other countries, the Russian bourgeoisie was entirely lacking in revolutionary quality. There, the task of the proletariat was to oppose the bourgeoisie, not to unite with it. But China's national bourgeoisie has a revolutionary quality at certain periods and to a certain degree, because China is a colonial and semi-colonial country which is a victim of aggression. Here, the task of the proletariat is to form a united front with the national bourgeoisie against imperialism and the bureaucrat and warlord governments without overlooking its revolutionary quality. At the same time, however, being a bourgeois class in a colonial and semi-colonial country and so being extremely flabby economically and politically, the Chinese national bourgeoisie also has another quality, namely, a proneness to conciliation with the enemies of the revolution. Even when it takes part in the revolution, it is unwilling to break with imperialism completely and, moreover, it is closely associated with the exploitation of the rural areas through land rent; thus it is neither willing nor able to overthrow imperialism, and much less the feudal forces, in a thorough way. So neither of the two basic problems or tasks of China's bourgeois-democratic revolution can be solved or accomplished by the national bourgeoisie. As for China's big bourgeoisie, which is represented by the Kuomintang, all through the long period from 1927 to 1937 it nestled in the arms of the imperialists and formed an alliance with the feudal forces against the revolutionary people. In 1927 and for some time afterwards, the Chinese national bourgeoisie also followed the counter-revolution. During the present anti-Japanese war, the section of the big bourgeoisie represented by Wang Ching-wei has capitulated to the enemy, which constitutes a fresh betrayal on the part of the big bourgeoisie. In this respect, then, the bourgeoisie in China differs from the earlier bourgeoisie of the European and American countries, and especially of France. When the bourgeoisie in those countries, and especially in France, was still in its revolutionary era, the bourgeois revolution was comparatively thorough, whereas the bourgeoisie in China lacks even this degree of thoroughness.
