Why is there identity here, too?

Why is there identity here, too? You see, by means of revolution the proletariat, at one time the ruled, is transformed into the ruler, while the bourgeoisie, the erstwhile ruler, is transformed into the ruled and changes its position to that originally occupied by its opposite. This has already taken place in the Soviet Union, as it will take place throughout the world. If there were no interconnection and identity of opposites in given conditions, how could such a change take place?

The Kuomintang, which played a certain positive role at a certain stage in modern Chinese history, became a counter-revolutionary party after 1927 because of its inherent class nature and because of imperialist blandishments (these being the conditions); but it has been compelled to agree to resist Japan because of the sharpening of the contradiction between China and Japan and because of the Communist Party's policy of the united front (these being the conditions). Things in contradiction change into one another, and herein lies a definite identity.

Our agrarian revolution has been a process in which the landlord class owning the land is transformed into a class that has lost its land, while the peasants who once lost their land are transformed into small holders who have acquired land, and it will be such a process once again. In given conditions having and not having, acquiring and losing, are interconnected; there is identity of the two sides. Under socialism, private peasant ownership is transformed into the public ownership of socialist agriculture; this has already taken place in the Soviet Union, as it will take place everywhere else. There is a bridge leading from private property to public property, which in philosophy is called identity, or transformation into each other, or interpenetration.
