Abstract: Historical stage is not equal to era.In Marx's view,only the historical stage with major historical themes and typical social contradictions can be called an era.An era is not only the process of giving full play to the power of man as the subject,but also the process of using the object as the power of the object,which is essentially a major revolutionary process.From the era of universal excitement,that is,the era of unlimited revolutionary enthusiasm,the proletariat stepped into the capitalist era of simplified class opposition to obtain the material conditions for political liberation.Only by entering the era of "revolutionary socialism" can we open the curtain of real human liberation;and only by understanding that the philosophical revolution is the forerunner of the social revolution of era can we grasp the quintessence of the ideological line of promoting social revolution with self-revolution.The new era of socialism with Chinese characteristics is the era of the unity of self-revolution and social revolution,so we need to absorb the revolutionary consciousness,grasp the pulse of the era,listen to the voice of the era and adhere to the practical logic from the concept of the era in The Communist Manifesto,responding to the needs of the era and answering the questions of the era.

Key words: The Communist Manifesto, view of the era, revolutionary consciousness, practical logic
