Two-point theory: in the process of studying the contradiction development of complex things, we should study both the main contradiction and the secondary contradiction; To study a contradiction, we should not only study its main aspects, but also its secondary aspects. Both should not be neglected. Emphasis theory is a dialectical way of thinking, which is opposite to equilibrium theory. It means that when studying the development process of complex things, we should focus on grasping their main contradictions. Expand the dialectical relationship between the main contradiction and the secondary contradiction of data.

The principal contradiction and the secondary contradiction are interdependent.

First of all, the principal contradiction and the secondary contradiction are mutually conditional. The main contradiction is the main contradiction because it is the main contradiction relative to the secondary contradiction. Without minor contradictions, there is no major contradiction. Similarly, small contradictions are small contradictions because there is no big contradiction, so there is no big contradiction.

Secondly, the principal contradiction and the secondary contradiction influence each other. The solution of the principal contradiction provides for the solution of the secondary contradiction. When the principal contradiction is solved, the secondary contradiction will be easily solved. On the contrary, the resolution of minor contradictions affects the resolution of major contradictions, and the resolution of minor contradictions is conducive to the resolution of major contradictions.

Under certain conditions, the status of the principal contradiction and the secondary contradiction is not static, but can be transformed under certain conditions, that is, the principal contradiction is transformed into the secondary contradiction under certain conditions, and the secondary contradiction rises to the principal contradiction under certain conditions. Methodological significance The principle of dialectical relationship between principal contradiction and secondary contradiction requires us to learn to distinguish between principal contradiction and secondary contradiction, and learn to distinguish between principal and secondary aspects of contradiction in practice.
