Research On "Never......before" Of Marx's The Preface To A Contribution To The Critique Of Political Economy

"Never......Before", presented in the Preface of A Contribution to the Critique of Political Economy, is Marx's consistent thought principle rather germination. Materialist conception of history should contain "Never......Before", which also forms one of the law groups of it. Marx and Engels have emphasized and elaborated it repeatedly in different occasions in different expressions in the Introduction to A Contribution to the Critique of Hegel's Philosophy of Right, The Poverty of Philosophy, Critique of Hegel's Philosophy of Right and other works. "Never......Before" probes into the requirement of social pattern replacement, the essence of the thought, and the requirement of human history mission by generalizing the principle meanwhile. Therefore, we regard "Never......Before" as one thought principle existing in the logic thinking of materialist conception of history rather than the supplement of "the Two Necessities". Herein, when dealing with the relationship between "Never......Before" and "the Two Necessities", the thesis insists that the former is not the supplement and development of the latter and both are included in Materialist conception of history. What's more, sticking to them is sticking to Marxism and either should be neglectedThe thesis is divided into four parts:The first part is introduction consisting of the cause and significance of the thesis, the research at home and abroad, research methodology and the innovation and difficulty of the thesis.The second part is the historical conditions of "Never......Before" including the historical background, the theoretical basisThe third part is the basic definition and the essence of "Never......Before". In the light of the classics of Marxism, this part observes and clarifies the basic definition of "Never......Before" and then grasps the essence of the thought and gives a new analysis on the relationship between "Never......Before" and "the Two Necessities".The fourth part is the contemporary connotation of "Never......Before".
