The essential feature of Marxist philosophy is also the essential feature of Marxism as a whole.

The essential feature of Marxism is the high unity of scientificity and revolution based on practicality.

1. The practicality of Marxism is that it is based on social practice and aims at transforming the world; It comes from practice and develops with the development of practice. The unity of theory and practice is the basic principle of Marxism.

Marx's famous saying is engraved on the Marx Monument at Highgate Cemetery in London: "Philosophers only explain the world in different ways, but the problem is to change the world." MNX1-19

2. The scientific nature of Marxism is truth, and Marxism is a correct reflection of the general laws of nature, society and human spiritual movement.

3. The revolutionary performance of Marxism lies in revolutionizing the existing world and guiding the proletariat and working people to overthrow all exploitation systems, build socialism and realize * * * capitalism through social revolution.

"... in fact, for practical materialists, that is, * * * producers, the whole problem lies in revolutionizing the existing world and actually opposing and changing the status quo of things." Mq1-48

"* * * producers disdain to conceal their views and intentions. They publicly announced that their goal can only be achieved by overthrowing all the existing social systems by violence. Let the ruling class tremble in the face of the * * * proletarian revolution. What the proletarians lost in this revolution was only chains. They will get the whole world. " Manifesto of the * * * Productive Party X1-286
