The core of Marxist materialist dialectics lies in contradictions, and this theoretical cornerstone reveals to us the internal source of power for the development of things. Contradiction, as the driving force behind the development of things, not only reveals the unity of opposites within things, but also reflects the internal laws of the development of things.
The basic attributes of contradictions, identity and struggle, are the key to understanding and grasping contradictions. Identity is embodied in the close relationship between the two sides of the contradiction that is interdependent, interpenetrating and containing each other. Just as the two poles of yin and yang, although opposite, they are interdependent, and together they constitute a complete world. This identity, which reveals the intrinsic connection and common nature between the two sides of the contradiction, provides us with an important perspective for understanding the complexity of things.
Struggle, on the other hand, refers to the mutual exclusion and antagonism of the two sides of a contradiction. In the struggle, the two sides of the contradiction are both opposed to each other and interdependent, which constitutes the internal tension of the development of things. This kind of fighting not only promotes the development of things, but also maintains the relative stability of things. In the struggle, new things are born and old things are extinguished, pushing the wheels of history forward.
Therefore, the identity and struggle of contradictions are the internal source of power for the development of things. Only by deeply understanding and grasping this core idea can we better understand things, reveal the internal laws of their development, and provide scientific theoretical guidance for promoting the development and progress of society.
When delving into the universality and particularity of contradictions, we can't help but sigh at the magical charm of contradictions everywhere. This charm comes from the universality of contradictions, which permeate every corner of the world like an invisible force, whether it is the vast natural world, the complex and changeable human society, or even the profound and abstract field of thought, contradictions are everywhere.
The universality of contradiction, the eternal theme, is not empty, but has a real expression. In the natural world, the alternation of day and night, the cycle of the four seasons, and the birth and death of life are all vivid manifestations of the universality of contradictions. In human society, the gap between the rich and the poor, the conflict between power and rights, and the struggle between freedom and bondage are all concrete manifestations of the universality of contradictions. Even in the realm of human thinking, the opposition between reason and sensibility, the collision between intuition and logic, is a profound manifestation of the universality of contradictions.
However, the universality of contradictions does not imply the homogenization of contradictions. On the contrary, each contradiction has its own unique personality, that is, the particularity of the contradiction. This peculiarity is reflected in the specific nature, status and role of both sides of the contradiction, making each contradiction unique. For example, in the social field, there is an essential difference between the nature, status, and role of the contradictions of capitalist society and the contradictions of socialist society.
This dialectical relationship between universality and particularity is precisely the essence of the problem of contradiction. It tells us that contradictions are both universal and specific. We need to understand the universality of contradiction without forgetting its particularity; In order to grasp the particularity of contradictions, it is also necessary to understand their universality. Only in this way can we comprehensively and deeply recognize and understand the contradictions, so that we can better deal with and resolve them.
When looking at problems, applying the viewpoint of unity of opposites means that we should gain insight into the inner nature and evolution of things from the interconnection and mutual constraints of the two sides of the contradiction. Every contradiction contains a major contradiction and a secondary contradiction, and similarly, every contradiction has its dominant and secondary aspects. This complexity requires us to analyze the problem in a comprehensive and focused manner. This is like a delicate painting, with both the harmony and beauty of the whole and the delicate portrayal of the parts. We can't just look at a corner of the scroll and ignore the beauty of the whole; In the same way, we cannot see only one aspect of the contradiction and ignore the totality of the contradiction. We need to uphold the unity of the two-point theory and the key theory, and we must not only see the relationship between the two sides of the contradiction in opposition and unity, but also grasp the main aspects of the contradiction and grasp the main contradiction of things and the main aspect of the contradiction, so as to find the key to solving the problem. In practical life, this kind of opposing and unified viewpoint and method has a wide range of application value. Whether it is the choice and decision-making in personal life, or the macro planning of social development, it is full of various contradictions. These contradictions are both universal and particular. Only through in-depth analysis and research can we grasp the internal logic of contradictions, so that we can better cope with challenges and promote the development of things. Therefore, we need to deeply study and understand the core ideas of Marxist materialist dialectics, and constantly improve our ability to analyze contradictions and solve problems. Only in this way can we find the right direction in this world full of contradictions and contribute to the development and progress of society.
