p Lenin called the law of the unity and conflict of opposites the essence, the core of dialectics. This law reveals the sources, the real causes of the eternal motion and development of the material world. Knowledge of this law is of fundamental importance for understanding the dialectics of development of nature, society and thought, for science and revolutionary practice.

An analysis of the contradictions in objective reality and disclosure of their nature are a major requisite for Marxist scientific study and practical action.
