So that this point may be clearly understood, we again utilize as examples the relationship between life and death, and the relationship between labour and capital: within an organism, the death of old cells is the precondition for the production of new cells, and is the precondition for the process of life. The two contradictory aspects of life and death are united within an organism, and also change into each other, live cells change into dead cells, and dead cells change into live cells (live cells are regenerated
The proletariat produces surplus value for the bourgeoisie, and the bourgeoisie exploits the proletariat’s labour power. This is a unified process which determines the survival of capitalism. Labour and capital are each a condition for the other’s existence. However, this condition has a given limit, and capitalist development must remain within this given limit; if it is exceeded, ruptures emerge in the unified process, and a socialist revolution appears. These ruptures emerge abruptly, but also emerge gradually in that preparations for their emergence commence from the day the two classes come into existence; the struggle of both sides is continual, and it is this which lays the ground for a sudden change. From this it can be seen that the coexistence of the two classes is preserved as a result of given conditions; this coexistence under given conditions produces a unity or identity between the two classes. Under given conditions the two classes also change from one to the other, such that the exploiters change into the exploited and the exploited change into the exploiters, and capitalist society is transformed into a socialist society. The two contradictory entities have an identity under given conditions. This is one problem. The two sides are in constant struggle. There is struggle within an entity, and especially the struggle of revolution. This unavoidable condition is unconditional, absolute, and inevitable. This is the other problem.[4-616]
In identity there is struggle.[4-617]To quote Lenin, “…there is an absolute in the relative”. Because of this, the unity of opposites is itself a manifestation or an element of the struggle of contradictions. This is our conclusion with regard to this problem.
According to this conclusion, it is perfectly evident whether or not the so-called theories of class harmony and the unity of ideology still have any standing. The theory of international class harmony becomes the opportunism of the workers’ movements in every country, and they have no other function than to simply serve as the running dogs of the bourgeoisie. China too has a so-called theory of class harmony, but this is a tune sung by bourgeois reformism. It has no other purpose than specifically to swindle the proletariat so that it will remain forever the slave of the bourgeoisie. The meaningless cliches of the so-called theory of the unity of ideology, directly or indirectly depend on the nonsense spewed out by officialdom that it is “the learned opinion of the scholars”. Its purpose is nothing but the suppression of the truth, and the obstruction of the progress of the revolution. True scientific theory is the law of the unity of opposites of materialist dialectics, and not these other melodies.
