These are the basic laws of materialist dialectics. Apart from the naive materialism of ancient Greece which simply and unsystematically pointed out some of the significance of these laws, and Hegel who developed these laws in an idealist manner, they have been repudiated by all metaphysical philosophies (the so-called metaphysical philosophies are theories opposed to the theory of development). It was only with Marx and Engels who transformed these laws of Hegel in a material way, that they became the most fundamental part of the Marxist world view [p. 237] and methodology.
Besides the basic laws outlined above and related to these laws are the following categories of materialist dialectics:
Essence and Appearance
(p. 301) Form and Content
Cause and Effect
Basis and Condition
Possibility and Reality
Chance and Necessity
Necessity and Freedom[2-281]
Chain and Link, and so on.
Of these categories, some were previously studied in depth by metaphysical philosophies and idealist dialectics, some were studied only one-sidedly by philosophy, and some were put forward for the first time by Marxism. In the hands of Marxist revolutionary theorists and practitioners, these categories have stripped away the idealist and metaphysical husk of former philosophies, overcome their one-sidedness, and discovered their authentic form; moreover, as the era progressed, they greatly enriched their content to become an important component of revolutionary scientific methodology. The combination of these categories and the basic categories mentioned above forms a complete and profound system of materialist dialectics.
None of these laws and categories is created by human thought itself; they are the actual laws of the objective world. All idealisms assert [p. 238] spirit creates matter, and from this perspective, the tenets of philosophy, its principles, laws, and categories, are naturally created by mind. Hegel, who developed the system of dialectics, perceived dialectics in this manner. He saw the laws of dialectics not as being abstracted from the history of nature and society, but as a logical system in pure thought. After human thought has created this system, it imposes it on nature and society. Marx and Engels stripped away Hegel’s mystical shell, discarded his idealism, and placed his dialectics on a material basis. Engels stated (p. 302): “It is, therefore, from the history of nature and humankind that the laws of dialectics are abstracted. For they are nothing but the most general laws of these two aspects of historical development. And indeed they can be reduced to three fundamental laws: the transformation of quality into quantity and vice versa, the unity of contradictions, and the negation of the negation”.[2-282] While being laws of the objective world, the laws of dialectics are also laws of subjective thought, and that is because the laws of human thought are none other than the laws of the objective world reflected in the brains of humans through practice. As was discussed previously, dialectics, epistemology, and logic are one and the same.
Why do we study dialectics? We study it for no other reason than to change this world, to change the age-old relationships in this world between humans, and humans and matter. The lives of the vast majority of this world’s humanity are filled with misery and suffering as a result of the oppression of the political and economic systems dominated by a minority. The people who live in China suffer a twofold cruel and inhuman oppression – national and social oppression. We must change these age-old relationships and strive for national and social liberation.
Why is it necessary to study dialectics to achieve the objective of changing China and the world? It is because dialectics is made up of the most general laws of development of nature and society; when we comprehend dialectics, we have gained a scientific weapon, and in the revolutionary practice of changing nature and society possess a theory and method suited to this practice. Materialist dialectics is itself a science (a philosophical science); it is the starting point for all sciences, and it is also a methodology. Our revolutionary practice[2-283] is itself also a science, called social or political science. If we don’t understand dialectics, our [p. 239] affairs will be badly handled; mistakes made within the revolution are those that violate dialectics. However, if dialectics is understood, immense results can be achieved; and if all things done correctly are investigated, it will be found they conform with dialectics.
Consequently, all revolutionary comrades, and above all cadres, should diligently study dialectics.
